Principles of Software Engineering (SEP521), KAIST- Fall 2009, Teaching Assistant,
Computer Science Project (CS408), KAIST- As a teaching assistant, I had the opportunity to mentor the senior undergraduate computer science major students for developing a software. In the fall course of 2009, Qualcomm donated $5,000 to this class, and mentors decided to give this prize money to the team that produced the best software. This prompted the students to work really hard on the projects. I took charge of two teams and met each team two times a week to help them select a software and the specific scope to be developed by considering the limited time and the number of men power. I also supported them to perform requirement analysis and software design such as drawing the architectural diagram, structural models, and behavioral models. For the final demo presentation, I helped them to make the clear and understandable presentation materials. Finally, one of the teams that I mentored was
chosen as the best team, and later, based on the ideas, theyfounded a new start-up company, Weclay Inc. They launched the video/voice call application,Seed, whichranked #1 most downloaded apps from the App Store in 2012.

- Spring 2008, Mentoring the high school student participating in the Intel International Science and Engineering Fair (ISEF), helping him win the
Grand Awardin the area of Computer Science- I had the privilege to mentor the high school student who had participated the ISEF 2008 with the project titled
Real-Time Water Wave Simulation with Surface Advection. During the summer vacation, I helped him find the uniqueness in his ideas and led him to focus on developing it. At the competition, he won the prize, the best of category award in computer science for top first place winner, and received the invitation to the Nobel Prize ceremonies in Stockholm. I was delighted to see him succeed in the honorable conference as a student who is from outside the U.S. and a non-native English speaker.

Introduction to Programming (CS101)using JAVA, KAIST- I had the chance to take part in teaching
Programming in Javafor non-computer science major students. The undergraduate students in the first year at Korea Advanced Institute of Science and Technology (KAIST), where I studied for graduates, do not belong to any departments but they experience their desired major beforehand to decide the right major in the second year. The “Programming in Java” was one of the mandatory courses to be taken for all freshmen students, and it was a great challenge to teach the students who do not want to learn programming. By applying several different teaching methods, I found the following ways to teach students to engage in interest rather than boring them: (i) Students are able to better understand complex concepts in real-life examples. For example, I used the vehicle examples frequently to understand the object-oriented concept—classes, objects, encapsulation, inheritance, and polymorphism, which was very effective. (ii) Students are more receptive when explaining with graphical notations rather than codes, and I used the abstract and intuitive diagrams such as UML. (iii) Students learn more quickly by having hands-on experience in the classroom with a small example. Non-computer science major students often feel very difficult to install the JDK or Java IDE and sometimes abandon learning from the beginning. When showing students step-by-step examples and giving them the opportunity to practice on their own, I noticed that understanding increased and participation in the class became more active.
