Workshop Recap

Emu spent a ridiculous amount of time putting together this video highlighting our experiences teaching at Yeomyung School in Seoul. I think it’s absolutely wonderful and surprisingly effective considering that we weren’t allowed to show students’ faces. Please watch the video!

Final Thoughts

That’s All Folks!

It’s only been five days since our STEM camp ended and already I miss my students, my team, and Seoul. I’m proud of my team for putting together a successful workshop, and I’m proud of my students for working so hard during these past two weeks.

Two of our students made us a thank you poster!

For my final blog post, I thought I would highlight some of the most memorable parts of this trip for me. Obviously, if you want more details, you should just read the rest of the blog 🙂

Projects

During the afternoons of Days 7 through 9, we had the students choose and work on their own final project. We wanted to give students the opportunity to explore their favorite workshop activity in greater depth.

There were some concerns with regard to how successful an open-ended project would be with this particular group of students, considering that many of them were accustomed to following step-by-step instructions. However, we were pleasantly surprised by how easy it was for students to come up with their own projects. I was in charge of the students who wanted to code using Scratch or Turtle. They all churned out beautiful projects if I must say so myself.

Other students focused on learning more suturing techniques, adding additional commands to the Google Voice Kit, building models of bridges, revamping the Raspberry Pi robots, and using the Pi Camera to create stop motion animation.

On Day 10, the students made posters for the projects and gave poster presentations in front of the class. They all presented in Korean, so I had no idea what exactly they said, but based on body language, the students seemed proud of their work.

After seeing how diverse the projects were, I felt especially proud of my team for putting together the workshop. So much planning went into the workshop, but it definitely paid off in the end. Never underestimate how much time and effort it takes to acquire supplies for hands-on activities. I probably missed a lot of major attractions in Seoul, but at the very least, I got to spend a lot of time at Daiso, Yongsan Electronics Market, and Emart 😛

Learning about Korea

Teaching an intensive two-week STEM workshop in a foreign country is hard work, but lucky for me, having amazing teammates made it that much easier. Emily and Emu were both Yeomyung School veterans, so they had a good idea of what challenges we would be up against. Before we even started teaching, they knew which questions to ask the science teacher, as well as what sort of curriculum and teaching styles would work best with our students.

Outside of the classroom, I also had the opportunity to learn about the Korean culture and language. I’ve traveled abroad several times in the past, but to be honest, this was the first time I actually felt like I truly learned something about the country’s culture. It had everything to do with having Shine around all the time. Shine was an endless source of information about Korean history and traditions, and she was patient enough to teach me some phrases in Korean even though I “slapped” the pronunciation. (Note: “Slapping” is a step up from “butchering” the pronunciation.)

Needless to say, I’m going to miss my team dearly, but as they say, all good things must come to an end.

Connecting with Students

I mentioned in my first blog post that my biggest concern was overcoming the language barrier with the students. As it turns out, all those years going to Chinese school paid off because I was able to communicate with nearly half of the students with my broken Mandarin! For the students who didn’t speak Chinese, a combination of using Naver Translate and Shine’s brain usually did the trick.

Also, remember the Sonic Pi fiasco? Well, turns out that the students really appreciated the program I wrote to play Yiruma’s River Flows In You. I’m not sure if it actually made them more interested in computer programming, but at least it showed them that I cared about them and that I honestly wanted them to have a good time with the workshop. As corny as it sounds, sometimes we just want to be cared for, and students at Yeomyung are no different.

Teaching at Yeomyung these past two weeks has been an incredible journey of ups and downs. Although I may never see my students again, I am grateful for our shared experiences of laughter and frustration, and I wish them all the best during the upcoming school year and beyond. To my students: if any of you are reading this, remember: “Mistakes are okay. Just try again!”

 

Internet, VR, Dry Ice, and More

During the next two mornings, we covered a variety of topics including the internet, virtual reality, and dry ice.

My first internet simulation activity (adapted from Code.org) was based on the game Battleship. However, rather than have multiple ships and only one opponent, this version allowed a single player to place one battleship for each of three opponents. Because this was an internet simulation, students had to communicate their intent to attack a particular board space by passing notes with To/From fields and the board coordinates. The message recipient would then indicate whether the chosen board coordinate was a hit or a miss. Once the students got the hang of the game, some actually got really into it.

Three students were absent, so Emily kindly stepped in and played as all three of them.

For the second internet simulation, I put together a mini network complete with clients, servers, and routers. The activity went something like this:

  1. Each of three servers served a different type of candy, and the students acting as clients needed to consult a Domain Name Server table to look up the IP address of the desired candy server.
  2. Student clients wrote the candy server IP address on a Ziploc packet and passed the packet to the nearest router.
  3. Each router had their own routing table, which told them the next destination of the packet (e.g. another router, client, or server) based on the destination IP address.
  4. Candy servers placed candy into each packet they received and revealed the client (source) IP address.
  5. The packet would make its way back through the network and arrive back at the original client.

Internet simulation

I’m actually not sure how much the students understood from the activity, but based on the number of candies students were accumulating, I think it’s safe to assume they at least understood how my internet abstraction worked.

The next day, we introduced the students to virtual reality using Google Cardboard. My original plan was to use Google Expeditions to lead virtual class field trips to places in America and Europe and to explore human anatomy from the inside. Unfortunately, the school’s poor wifi connection forced us to ditch this plan. Instead, the students chose their own virtual reality apps from the Play Store/App Store and explored their own interests individually.

Afterward, Emu led dry ice experiments using dry ice that Baskin Robbins gave us with our ice cream cake purchase. Dry ice was a hit, as was the ice cream cake 🙂

The final Raspberry Pi activity was actually a leftover activity from the first week. Students were supposed to make an ultrasonic theremin by building a simple circuit and connecting it to the Raspberry Pi. By connecting an ultrasonic distance sensor to the Raspberry Pi, Sonic Pi can play different sounds based on how close or far your hand (or any object) is to the sensor. For reasons still unknown to us, we couldn’t get the Raspberry Pis to output meaningful values from the ultrasonic distance sensors. We even stayed in during lunch time to debug but to no avail.

IMG_3266
Debugging sensors during lunch

Although the theremins ended up not working, we were very proud of the progress the students had made since day one when they were first introduced to Raspberry Pi. By week 2, students knew how to connect all the computer peripherals as well as navigate Terminal and Python IDLE windows with relative ease. Even though some students might not be huge fans of using the Raspberry Pis, at least they are better equipped to work with computers in the future if they ever need to do so.

Biology Day

Week 2 started off with a morning dedicated to biology activities. Emily whipped out her signature microscope lab, which has been a hit for three consecutive years. The students had a blast competing against each other to locate specific objects on various bills and coins.

For the next activity, students learned about viruses and built their own models of the HIV and Zika viruses.

Paper models of viruses

The students also tried their hand at performing surgery…on bananas. Practicing interrupted and continuous stitches on bananas was definitely a crowd-favorite. Some students loved the activity so much that they wanted to know exactly when they could suture bananas again.

We were fortunate enough to eat lunch with the Principal of Yeomyung School. Over lunch, we learned more about his professional background in education and more about Yeomyung. After lunch, he had a meeting with someone from Germany, which made a lot more sense after Shine explained to us Korea’s relationship with Germany after the Korean War.

In the afternoon, Emily taught the students how to use the Raspberry Pi camera. With just a few lines of code, the students were able to create their very own photo booth complete with assorted filters.

Biology day was a huge success, and I know for a fact that our students who were less technology-inclined really enjoyed the break from computer-related activities.

After class, the team enjoyed fried chicken at BHC (Better & Happier Choice) for dinner. Emu underwent some harsh criticism for ordering orange juice, though I heard it tasted delicious.

To end the day, Shine introduced us to coin karaoke. It’s just like normal karaoke/norebang, except you pay by song rather than by the hour. It’s perfect for smaller groups and youth.

Oh, how I wish coin karaoke existed in the US… Anyway, that’s a wrap for week 2 day 1!

Spontaneous Sunday Excursions

On Sunday of Week 2, Emu and I originally planned on visiting Gyeongbokgung Palace for an hour or two before returning back to the apartment to work. Instead, we ended up staying out for more than five hours because we kept finding new attractions to explore in the area.

 

After leaving the palace, we crossed the street to visit the statue of King Sejong the Great, the creator of Hangul. We noticed there was an entrance to something called King Sejong Story at the base of the statue, so we decided to check it out. We expected to see a single room showcase highlighting his life accomplishments, but instead, we discovered an entire exhibition with 9 different sections covering 3,200 square meters.

The exhibition also linked to the KT building and the Sejong Center for Performing Arts. I’m not sure exactly where we were at the time, but Emu and I found an activity where we wrote our names in Hangul using the fancy calligraphy brushes.

 

We also enjoyed some bulgogi hot pot at one of the restaurants nearby. I’m proud to say that we got by even though Shine wasn’t there to translate for us.

 

In the morning, when we were back at Gyeongbokgung Palace, Emu and I noticed a really pretty-looking pagoda but realized it was disconnected from the palace grounds. It turned out to be part of the National Folk Museum of Korea, which we finally visited after lunch. I don’t think we actually visited the permanent exhibition halls, but we really enjoyed exploring the street from the past.

On our way back to the subway station, Emu and I stopped by the National Museum of Modern and Contemporary Art. We didn’t have time to enter the museum, which was unfortunate because Emu is actually really into art. However, we did stop by the nearby Osulloc Tea House, where Emu enjoyed a lovely green tea latte.

IMG_9264
Emu and her green tea latte

In the evening, we split up and did our own thing. I had dinner with my cousin-in-law in Gangnam followed by green tea ice cream from Baskin Robbins.

All in all, I’d say it was a pretty productive Sunday. Stay tuned for updates from week 2!

Making things move

On Friday, Shine started off the day with mousetrap cars. The students seemed to enjoy putting all the pieces together, and we just so happened to have duct tape that matched the colors of each time (i.e. pink, yellow, green, and blue). Emily sacrificed a pen to show the students what would happen if someone’s finger got caught in the mousetrap. I think that demonstration sufficiently scared the students and made them work more cautiously.

Once everyone had a working mousetrap car, we raced them. I even drew a makeshift checkered flag, green flag, and a diagonally divided black-and-white flag. In case anyone is interested, a diagonally divided black-and-white flag is used to indicate a penalty for unsportsmanlike conduct, at least according to Wikipedia. I felt super cool waving around my flag, but I think Emu and Emily carried their flags just to appease me.

The next activity was nail art. We passed out cork boards, nails, and thread to all the students and let them make whatever they wanted. It was a nice laid back activity for a Friday, and most of the students seemed to enjoy it. Some people even drew their design on a white piece of paper, cut out the design, and used it as a template for their nail art.

After lunch, we revisited the robot activity from the day before, except instead of running a hard-coded robot dance, we had the students write a program that allowed them to remote control their robots using their phones. The library is called BlueDot, and it’s actually super easy to use. I definitely encourage you to check it out if you ever want to control your Raspberry Pi using Bluetooth. The biggest struggle we faced with this project was making sure that all the students connected to the correct phone because many of them had the same name (e.g. Nexus 5). Emu got around this by renaming people’s phones.

Fun fact: Emily’s phone is now called “Sophia,” and my phone is now called “Billy and Daniel.”

After this activity, Emu asked one of our students who originally wasn’t a fan of our programming projects if he liked computers now, and he said “yes,” although begrudgingly. I still consider that a success.

To celebrate completing our first week of teaching, Emu, Emily, and I went out and ate a lot of delicious food. Shine is Miss Popular and has plans with other friends this weekend, so, unfortunately, she didn’t join us.

We also did a quick Daiso and Artbox run, and I made some purchases to add to my growing collection of Boss the Shark items. No shame.

That’s all for now folks. I’m about to leave for a pottery excursion with Emu and Emily, so stay tuned for updates.

Day 3

In the morning, Emu taught a module on circuits, which included an activity where students deconstructed a flashlight, made their own flashlights, played a game to learn how to read resistors, and built simple circuits using a breadboard. The flashlight activity was a big hit with all the students, though, for some reason, none of them actually wanted to keep their flashlights after they made them.

Some students were more interested in circuits than others, and some students also came in with much more experience building circuits than others. The group that I worked with got pretty frustrated with all the wires, but when we finally got the button to turn on the LED light, I could see how surprised (but happy) they were that it actually worked. Also, it was neat for them to see the Raspberry Pi being used as a power source.

In the afternoon, my original plan was to have the students make their own speakers and then use that for audio output for the ultrasonic theremin and music box Raspberry Pi projects. Unfortunately, that plan didn’t work out. Here’s why.

The speaker activity involves cutting up the audio jack portion of a set of earphones and connecting the phone plug wires to the two ends of a copper wire coil.

The electric current going through the copper wire loop creates a magnetic field, and based on the direction of the electric current, the magnet will either attract or repel the copper wire loop. The copper wire coil is taped to the styrofoam cup, so when the coil moves, the cup also moves, which creates vibrations in the air and makes a sound.

The speaker activity wasn’t as successful as we would have liked. Whether it was the result of buying super cheap earphones with flimsy phone plug wires (10 for $20, whoop whoop) or the result of having imperfectly shaped copper wire loops, we aren’t quite sure. On the bright side, one of our students seemed super intrigued by the debugging process and was determined to make his speaker work even though the supplies were not ideal. Not everyone got their speakers to work, but enough of them worked that the students hopefully didn’t think I was crazy.

Remember how I said that I had planned to use the speakers for the next two Raspberry Pi activities? Well, now we ran into the issue of the speakers not working, but the only earphones we had were cut up to make the speakers. You might be thinking to yourself, “Wow, Kelsey sure can’t plan ahead.” Those were my thoughts exactly.

Fortunately for us, we had access to the computer lab downstairs, so we ditched the Raspberry Pi projects and showed the students how to program using Scratch. We only had about 40 minutes of class left, so we were pretty lenient with what the students actually did. Some students started going through the Scratch tutorials in Korean, and the others played games that other Scratchers had made. We figured that as long as the students were doing something related to Scratch, we would allow it because, at the very least, the people playing games would realize that it was possible to make fun games using the Scratch platform.

On the way home, we stopped for dinner at a place that served pig’s feet.

We still had to do a lot of preparation for day 4, so the moment we got home, we opened up shop. We had to solder 8 Motor HATs for the robots, so we set up some sketchy soldering stations in our apartment.

It was fortunate that we had bought two extra Motor HATs because someone—I’m not naming any names—accidentally soldered the header onto the wrong side of a Motor HAT board, and another Motor HAT was missing the header part. Afterward, I stayed up until 1 AM again flashing SD cards and downloading all the libraries necessary to make the robot move. As it turns out, all the preparation was totally worth it.

Day 4

Shine led the morning activities, which included a marshmallow tower challenge, a straw bridge challenge, an egg drop challenge, and finally a word search challenge. I think out of all the activities we’ve done so far, these were the ones with the highest participation rate. Usually, we would have a few students who were super tired and who would just put their heads down and sleep. Because these activities were all team-based, however, team members would pressure each other to work instead of sleep. As Emily so eloquently explained, “Even the most controlling one realizes that the others can be employed as labor.” Students would actually wake up their teammates and tell them what to do, which I found entertaining. Emu took some awesome photos, so hopefully, she’ll post some more in the near future. In the meantime, enjoy some photos I took on my phone.

In the afternoon, Shine and I had the students assemble robots. I gave them a handout with all the instructions, but some students still ran into difficulties. Emu and I ended up setting up a debugging station in the back of the room. We spent thirty minutes swapping out different parts for one problem robot before realizing that the students had just put the batteries in backward. We were so relieved when we finally got it working, but we were also slightly embarrassed that it took us so long to discover the problem.

We ate dak-galbi in Myeongdong for dinner. It was delicious but spicy.

To be honest, I fell asleep pretty soon after getting home, so that’s that for my day 4 update.

Murphy’s Law Strikes

In preparing for battle I have always found that plans are useless, but planning is indispensable.

–Dwight D. Eisenhower

We’ve officially made it through the first two days of camp! It has been an exhausting two days, but I’ve really enjoyed getting to know our students, and we’ve accomplished a lot already.

IMG_5107
Classroom all set-up and ready to go!

On day 1, Emily spent the morning teaching the students basic English words like “help” and “repeat.” Most of the students were already familiar with the words, but they seemed to enjoy playing our word games anyway. We played a modified version of tag that transfers the role of “it” to different players when various vocabulary words are said aloud.

I also got a chance to practice the four sentences of Korean that I knew! Apparently, the question “Do you need help?” sounds pretty similar to “Do you need money?” because the students gave me confused looks when I tried to ask them if they needed help. On the bright side, I quickly learned how to say, “I need money,” which could be useful in the future 😛

For lunch, we had soondubu (tofu soup) at a nearby restaurant.

IMG_5110
Soondubu for lunch

In the afternoon, we whipped out the Raspberry Pi computers, and Emu walked the students through an activity using the Google Voice Kits. Although we had some issues with slow wifi, it was cool to see how excited the students were when they finally got their Voice Kit working. The Voice Kit mimics Google Assistant and can answer questions preceded by the phrase, “Ok, Google.” If only we could get Google Assistant to work in Korean without too much hassle… that could be a task for the team next year 🙂

IMG_5109
Classroom after the Voice Kit activity

As soon as class let out and the students left, our team started preparing for the next day’s activities. There was a slight blip in our supplies ordering process, so we were short on Raspberry Pi cameras. Shine and I dashed to Leocom (part of Yongsan Electronics Market) and bought their last Pi camera in stock. We made it to the store fifteen minutes before closing time, so we were very proud of our accomplishment. I think this was our fifth consecutive day in Yongsan. We’re so familiar with the area at this point that we could give tours of the place.

IMG_5111

On the way back from Yongsan, I used my expert skills at spotting the word 약 to find a pharmacy for Shine. I was very proud of myself. We also picked up fried chicken for dinner from BHC, which was delicious.

The rest of the evening consisted of heavy-duty preparation for day 2. We had a detailed day 1 debrief where we discussed each of our students and assessed their English and STEM abilities. I was dead tired at this point and lying on the ground, but for what it’s worth, I think we did a pretty good job of evaluating our students’ strengths and weaknesses based on a day’s worth of interactions with them.

The objective of day 2 was to introduce the students to computer programming. I was in charge of both the morning and the afternoon, so I was pretty stressed out all day. The morning went better than I imagined. I taught the students how to play hangman, and they seemed to really enjoy it.

We then moved down to the computer lab, and I had the students work on drawing pictures using a block-based programming language that could be set to English, Korean, or Chinese. I wanted the students to focus on computational thinking instead of getting caught up in programming language syntax or the language barrier, so the Turtle Blockly-based game worked perfectly. I was super happy to see how much a lot of the students enjoyed it. Some of our students who weren’t as engaged yesterday actually showed interest in programming, which was wonderful to see. After the block-based programming language, I switched the students over to some basic Turtle programming with Python. Many students picked it up quickly, though to be completely honest, the programming was still very basic.

Sitting in front of a computer for a long time is very energy-consuming. When it was clear that the students had checked out and were having trouble concentrating, we moved back to the first floor and held a hangman competition. It was awesome to see students who participated less frequently actually volunteer to choose words for their team. Some even used dictionaries and the Internet to find new words that they thought would be difficult. For a game that we introduced somewhat by chance, it certainly helped us achieve many of our objectives.

They ran out of lunch for me and Shine, so we ended up grabbing katsu from the restaurant next door. Apparently, the restaurant had been featurd on television in the past and was visited by numerous celebrities.

IMG_5114
Katsu for lunch

Murphy’s Law struck during the afternoon. Everything that could have gone wrong went wrong, but I did my best to alleviate any problems that arose.

As part of the Voice Kit activity from Day 1, we had flashed the Raspberry Pi SD cards with a special Voice Kit image. This specific operating system was based on Raspbian but had some additional scripts pre-written for the Voice Kit activity. Because it looked so similar to the default Raspbian distribution on the official Raspberry Pi website, I assumed everything would work fine if we reused the Voice Kit image for the remainder of our activities.

I was wrong. The official distribution of Raspbian has an application called Sonic Pi pre-installed. However, as it turns out, the Voice Kit image does not have Sonic Pi installed. The entire afternoon was dedicated to working with Sonic Pi, which is obviously impossible without the software. We had all the kids open up a terminal window to download Sonic Pi from the internet, but because of the unreliable wifi, it took a really long time for the software to download.

Somewhat fortunately, I had an extra activity from the morning that did not rely on Sonic Pi. It involved playing a game that is meant to familiarize people with basic terminal commands. It was definitely not a crowd favorite, but at the very least, it probably made the terminal seem less daunting to the students. I don’t expect any of them to actually remember the commands, but next time they use the actual terminal on the Raspberry Pi, they will have some idea of what each command does.

Terminal

The problems didn’t stop after Sonic Pi finished installing. Sonic Pi is a programming environment that allows users to create music by writing lines of code. Obviously, it would be nice to hear the music that you create, but (not so) lucky for us, the audio jacks on the Raspberry Pis were not working. I ended up telling everyone to reuse the Voice Kit hat from yesterday, which sent audio output to a speaker.

Speaker from the Voice Kit

At that point, I was pretty stressed out because of issues with downloading Sonic Pi and getting audio playback to work, but I think the students who got it working, in the end, had a fun time. When I got back home, I wrote the code to play Yiruma’s River Flows in You using Sonic Pi; I plan on showing it to the class today to convince them that programming using Sonic Pi is pretty cool after all.

After our team debrief, I spent the rest of the evening trying to troubleshoot the audio situation on the Raspberry Pi. Apparently, the Voice Kit image not only had additional scripts pre-written, but it also had special audio settings to make the Voice Kit Hat + speaker combination work. Those audio settings redirected the audio output to somewhere other than the audio jack. Instead of fiddling with the Voice Kit image, I decided to flash all the Raspberry Pi SD cards with the official Raspbian image with all the default settings.

Easy enough, right? No. It took me 3.5 hours to simply download the Raspbian image (1.7 GB) from the internet. It also didn’t help that I accidentally put my laptop to sleep halfway through the first attempt, which meant that I actually spent 5 or so hours waiting for the download to finish. By the time I finally got around to flashing SD cards, it was already past midnight. I am so grateful, though, that everything after that went smoothly.

All in all, I think our preparation has been super useful. We’ve had to deal with unexpected problems—I guess that’s what you get when you have unit tests but no integration tests—but we resolved them with as much grace as we could muster. We continue to spend our evenings frantically preparing for the next day’s activities, and I’m confident that the additional preparation will pay off even if things don’t go as planned.

Evening preparations

Efficiency and the Honor System

Our team split up in the morning so that we could purchase supplies from different stores in parallel. Shine and I were in charge of electronics, so we made another trip to Yongsan Electronics Market to buy extension cords. We’re starting to become usual customers…

IMG_4980
Day 2 Breakfast at Paris Baguette

On the way to the market, Shine shared more of her Korean culture knowledge with me. Here are a few selected tidbits:

Hanja: Chinese characters in the Korean language. Before Sejong the Great created Hangul, most Korean documents were written in Hanja. When Shine was growing up, students learned how to read Chinese characters starting in the first grade. Learning Hanja is useful for understanding the etymology of Korean words that are based on Chinese words. Also, Hanja is sometimes used instead of Hangul when it is more convenient. For instance, sometimes 男 (“boy” in Hanja) is used in place of 소년 (“boy” in Hangul) because it is assumed that most Koreans can read the Chinese character. There is a many-to-one mapping of Chinese characters to Hangul (because Korean lacks a tonal system), so Hanja is often added to clarify meaning. There are also instances in which Hanja is always used. For example, when 故 (“dead” in Hanja) is used to precede the names of deceased individuals, Hanja is always used to show respect to them.

Lightly chilled subway cars. Some subway cars have signs that indicate that they are lightly chilled (as opposed to fully chilled), which I thought was really interesting. Part of the reason is to save energy, and part of the reason is that some people prefer not to have air conditioning on full blast during summer months.

Couple rings. A girl was sitting across from us on the subway when a guy walked in front of her and started touching one of her hands. At first, I was confused because I didn’t realize the two people knew each other, but Shine explained everything to me afterward. In Korea, when a couple starts dating, the boyfriend will buy the girlfriend a ring. The girl and guy we saw had just broken up, so the guy was trying to take the ring off her finger. Eventually, the girl just took the ring off herself and gave it to him. He got off the train at the next station. Everything happened in silence because in Korea, making a scene in public is frowned upon.

Honor system for trains. The newer turnstiles in the subway stations don’t have a physical barrier. In other words, you technically don’t have to swipe your T money card in order to board the train, but the collective society expects that people will swipe their cards anyway. The honor system works pretty well in Korea.


Our next stop was emart. We were greeted by an employee who bowed to us as we entered the store. Apparently, that is his sole job: to greet every single customer. It must be tiring, but at least he had a standing mat.

In order to use a shopping cart, you need to insert 100 won into the panel on the handle. This is the brilliant part: when you return the shopping cart back in line and re-attach the chain, you get your deposit of 100 won back. It incentivizes people to return their shopping carts in an orderly fashion. What a concept. Whoever came up with this idea is a genius.

Also, emart has a bunch of sloped sliding platforms for the shopping carts. The best part is that the wheels automatically lock once they’re on the moving platform. Again, genius.

We managed to find a lot of items we needed, which was great. I also noticed they were selling batches of plastic fake bananas and was equally confused and amused.

Afterward, I learned that emart has packing stations, where you can pick up free cardboard boxes and use them to carry your purchased goods. They even provide clear tape and packaging ribbon for you to use! Now, this is what I call effective recycling and reusing, not to mention the machines are pretty fun to use.

Shine and I lugged our morning’s purchases all the way to the school where we met up with Emily and Emu. We were pretty sweaty by the time we made it up the hill, but at least we were rewarded with a filling lunch at the school. I think I have a new favorite dish: dakgangjeong (닭강정). It’s a deep-fried crispy chicken dish with sweet potatoes, and it tasted delicious. 10 out of 10 would recommend.

Graduation was that day, so we got to see a bunch of students and teachers throughout the building. Some students who had participated in the workshop last January stopped by to say hi to Emily and Emu. It was great to hear that a lot of them were going on to attend university. Some are even planning on studying STEM subjects!

Our reunited team spent the afternoon setting up supply kits for the students. Everything is packed to perfection.

IMG_5009
All packed up and ready to go for Monday

We celebrated by eating manju at the Myeongdong station. Yum!

 

In the evening, we had a wonderful mixer with another MIT GTL Korea team. We ate at a restaurant near Gangnam, and I ordered rice cake and dumpling soup (tteok-manduguk). It was cool to hear about the other team’s challenges with their schools, especially because MIT has never worked with their schools before.

Shine and I went back to the apartment pretty soon after dinner, but Emily or Emu might post about their adventures post-dinner 🙂 Stay tuned!

Touchdown in Korea

As of yesterday, our entire team has landed safely in Seoul and moved into our Airbnb apartment! For our first team dinner, we had garlic fried chicken—more flavor than generic fried chicken but not too spicy either—and complimentary corn pops (unofficial name).

Day 0 Dinner: Garlic fried chicken and corn pops

Today was our first full day together in Korea, and I’m super proud of how productive we were. We left the apartment around 9 AM and grabbed breakfast on the way to the train station.

Day 1 Breakfast: Paris Baguette

Up until today, our biggest concern was purchasing 9 sets of computer monitors, keyboards, and mice for under $900. A significant portion of our curriculum involves working with Raspberry Pis, which meant that finding or not finding these monitors would make or break our workshop. After browsing online, we quickly realized that computer monitors under $100 are pretty difficult to come by, so we weren’t sure how successful we would be. In hindsight, we could have done a better job with risk assessment…

Fortunately, we learned about the Yongsan Electronics Market and took the subway there first thing after breakfast. This place is like paradise for any computer geek. There are thousands of shops that sell various electronics, including computer hard drives, GPUs, and gaming keyboards, all at wholesale prices.

Not only did we find great deals for wireless keyboards and mice, but we also found some ridiculously cheap used monitors, which were perfect for our use case.

We managed to purchase all 9 monitors for 250,000 won total. If that’s not a great deal, then I don’t know what is. Rest assured, every one of the monitors works perfectly (we checked).

The best part of the trip to the electronics store besides getting awesome deals on everything was probably seeing the confused looks on the shopkeepers’ faces. We were the only females shopping at the electronics market, so I guess people took notice. I must say we did look pretty badass lugging around boxes and a suitcase full of electronics, though.

We didn’t have much time for lunch before our meeting with the science teacher, so we enjoyed some Korean pizza while lounging on the bedroom floor.

Day 1 Lunch: Korean pizza

Shine was our main channel of communication with the science teacher during the semester, and both Emily and Emu taught at the school in previous years, which meant that I was the only person who had never spoken to the science teacher. Although I don’t speak a word of Korean, and the science teacher has limited English ability, I could tell by the way he talked about his students—thanks to Shine’s amazing translations—that he knows a lot about and cares a lot about his students.

I got to see the inside of the classroom and the computer lab for the first time, and it was all very exciting. This was the first school I’ve been to that requires people to take off their shoes and wear indoor slippers. We learned that our students are a bit older than we expected (between the ages of 17 and 30) and that their English ability is limited to the alphabet and basic words. I have a decent amount of experience teaching different audiences, but I’ve never had to teach a group of students who didn’t speak English, so that’s probably going to be my biggest challenge. Let’s hope that my carefully crafted slides with lots of animated pictures will help me get the main ideas across. In the worst case scenario, we have Naver translations.

Quick side story: I learned yesterday that even Google Translate can be a bit rough. Shine was looking through my slides and laughing at some of the improperly translated Korean, which I copied from Google Translate. She was kind enough to help me fix everything, though 🙂

My team and I have put a lot of time and effort into prepping all our activities for our STEM workshop. After talking with the science teacher, I’m even more excited to meet our students on Monday. We’re going to have a blast during these next few weeks!

Shopping for supplies resumed immediately after our meeting. Our next stop was the eight-story Daiso in Myungdong. Yes, that’s right. I said eight stories.

We spent a few hours at Daiso and bought more than 150,000 won worth of stuff. The lady at the cashier definitely gave us some weird looks, but according to Emu, they spent even more money at Daiso last year.

After bringing all the supplies back to the apartment, I decided to do a test run of the Expeditions virtual reality app for Google Cardboard with Emu and Shine. They seemed to get a real kick out of it, so I think the students will enjoy it, too. The nice thing is that you don’t have to know English in order to enjoy VR.

Emu and Emily were craving chicken and cheese, so we ended up going to 내가찜한닭 동국대점 for jjimdak.

The food was delicious (probably my favorite meal in Korea so far) but also spicier than anticipated. We went through at least 4 jugs of water, which got us some confused looks from the waitress. Perhaps it was because we had ordered one spicy jjimdak (for Shine and me) and one non-spicy jjimdak (for Emily and Emu), yet we were all low key dying from the hotness level. The waitresses’ facial expression was priceless when she told Shine that the non-spicy jjimdak had nothing but soy sauce and thus should not be spicy at all. My favorite quote from the night was from Emu: “We’re all eating food that we think is spicy.” Indeed, there has never been a truer statement. I cannot imagine how spicy the extra hot jjimdak would have been…

I’m super happy with how much we accomplished today. I think we’re definitely coming together as a team, and sharing personal stories about each other while chugging water has definitely added to our growing collection of shared team memories.

Tidbits

Conflict of interest in levels of formality. During our meeting with the science teacher, we learned that a decent number of our students are older than we are. In many cultures, this wouldn’t be a huge issue, but when speaking a language like Korean, which has different politeness levels, sometimes there are conflicts of interest in determining which level of formality to use. In general, the older person is higher in the hierarchy, which means the younger person should speak to the older person with greater formality. However, students must also speak to their teachers with greater formality, which makes this situation more complicated. Here the student is older than the teacher. Shine mentioned that a similar conflict of interest occurs with army rank versus age, which is why men are encouraged to join the army at the same age as everyone else to avoid frustrations of reporting to a higher official who is also younger.

Recycling. My family dropped me off at the apartment yesterday, and Shine picked us up from outside the building. As we were walking in, however, the security guard stopped us and lectured Shine for a solid 3 minutes or so. I thought it was an issue of bringing in outside people into the apartment, but apparently, the security guard was just concerned about making sure that all the guests recycled properly. Foreigners don’t have a great track record of recycling, and as an American, I can see why. Korea, unlike America, is big on recycling, and people can actually get in trouble for doing a poor job of recycling. Apparently, our apartment building has been called out for it in the past, so we’re all trying our best to recycle properly.

Black dogs. Our apartment is located near a street full of pet stores selling puppies. We saw two adorable black dogs (sorry, I’m bad with dog breeds) from outside the window, but Shine explained that they would probably never get adopted by Koreans because there is a stigma against black dogs in Korea. She mentioned, however, that South Korea’s new president actually adopted a black rescue dog, which was a departure from the tradition of adopting a pure-bred white Jindo dog to be the “First Pet.” Times are a-changin’.
