Korea's e-Campus Vision 2007: a New Learning Environment for Linear Algebra Sang-Gu Lee with Yoonmee Ham Sungkyunkwan Univ., KOREA sglee@skku.edu Kyonggi univ., KOREA ymham@kyonggi.ac.kr |
Abstract
We are introducing a new learning environment for linear algebra at my university, and this is changing our teaching methods. Korea's e-Campus Vision 2007 is a program begun in 2003. At Sungkyunkwan University, most of our lecture rooms are now equipped with beam projector, Viewcam, tablet PC and internet D-base. This provides a modern learning environment for our linear algebra classes. Computer demonstrations are easy, and lectures can easily be recorded so that students can review them right after class. We will discuss some of the positive effects that we have experienced.
Key words : learning environment, e-Campus Vision, blended learning (Model)

1. What is e-Campus Vision 2007 ?
In December 2002, the Korean government established ¡¸e-Campus Vision 2007(2003¢¦2007)¡¹. This comprehensive measure for university information utilization is a long-term plan to improve the education and research facilities of Korean universities. Department of Education (DOE) of South Korea decided to invest KRW 700,000,000,000-Won (690Million US$, KRW 1,020=US$ 1) over 5 years to innovate educational environment at colleges of Korea. This e-Campus Vision 2007 indicated the following 5 goals:
¨ç Effective IT use in research and education
¨è Clear and productive college administrative service
¨é Facilitate usage of IT environment at college with an emphasis on education
¨ê Improve security of cyber space with law and facility
¨ë Domestic and international service through advanced IT environment [MOE-Korea (2002)].
In order to achieve the goals, three directions were suggested:
¨ç Quality motivation from quantity expansion
¨è Cooperative alliance management from individual college management
¨é Lead policy from Catch-up policy with member¡¯s own and alliance¡¯ own motivation.
The government supports all the above efforts with Pumping Policy.
DOE classified new lecture rooms in the following category:

Before we start, we may note that Educational Broadcasting Service(EBS) of Korea have given Internet broadcasting service of K-12 lectures. Recently most of the best classical lectures of high school teachers for National SAT exam has been added on it through internet since 2004, this service was intended to fill the gap of opportunity between urban, rural and island region students. But this system still are using video recording of traditional lectures with the help of cameraman. At Sungkyunkwan University, we did want to overcome the limit of this old system from the beginning. So our new system do not require any extra technicians to do all the above and the quality of recorded lectures are as good as original one. In addition, we were thinking about improvement of our regular off-line lectures not cyber lectures, but we also wanted to add all the advantage of on-line resources to our off-line classroom. It is called as ¡®Blended-Learning¡¯.
With US$3.5million (KRW 3,600,000,000-) of the financial support from DOE and its own resources, the Sungkyunkwan University utilized its own committee. As a member of the committee, the author and members designed e-Learning and Blended-Learning capable our own e-lecture rooms that meet the most of the above DOE criteria. Our goal was indicated as 4A (Anyway, Anywhere, Anytime, Anyone) learning environment. The significance of our model is we only use our new lecture table and internet resources to meet all of the suggested needs. This means it did not cost much. We named this classroom model to ¡¸e+ lecture room¡¹. We introduce this system and how this learning environment altered our teaching method.
With the limited budget, we were trying to use minimum amount of hardware and use more of virtual resources that we could utilize. In order to do so, we did try to use our own regular classroom and university¡¯s internet resources only.
At the first stage, we wanted to be able to visualize the concepts in Linear Algebra. Also we wanted to have our classroom that we can
We did design them in the spring semester of 2003 and remodeled 8 rooms for e+ lecture room over the summer break.
First, we needed an updated internet system and software and also needed a new instructor¡¯s table that have all required hardware with enough security. We got help from a designer to make a right one. We heard that he now have a patent for the desk in the figure. We did use them for regular undergraduate classes of Fall 2003. Even though there were several difficulties on the full use of this new system, the effect was very positive. Students started to love most of the features and their performance was much better than before. The test scores at the final were far better than other classes of same title. During the winter vacation, another 20 rooms were remodeled and about 260 regular lectures were given from this new lecture rooms over the first year. Since then it is now a usual classes. The university just finished the 3rd stage of remodeling at Mar 29, 2005. By Mar 29th, 2005, 100% of classrooms (161 rooms) except very small (less than 29 person capacity) seminar rooms in the university are now e-lecture room with projection equipment and electronic lecture table, tablet PC with internet connection. We now show how the system looks like at e+ lecture room that I am using.
Internet Connected Tablet PC for instructor, Beam Projector and Speakers,
[View of new regular e-lecture room and e+ lecture room]
Now every 2-4 departments group of size 30-40 tenure track professors have at least one e+ lecture room with projection equipment, Viewcam, tablet PC and internet D-base (24 e+ lecture rooms). Since we can record most of our class activities, these rooms are used for Blended-learning. And four extra large classrooms for distance learning are better equipped with more viewcams, one professor can give a lecture for several different classrooms at the same time in this classroom.

[System of new lecture table equipments]
(With our lecture note, we can write on tablet monitor, the viewcam transmit instructor¡¯s activity and PC transmits everything on the Tablet PC with writing and sound. And same lecture can be viewed in real time, everywhere through the internet. Furthermore all are saved and can be reviewed right after the lecture over and over again.)

3. What is our new Learning Environment?
We now use tablet PC and white board. That is the only differences. But we can explain, write, read, go, find, see, do, hear, discuss and furthermore students can review the lectures not only text but also real lectures with sound and movie clips of their own instructor right after the class, even can enjoy real time class activity from remote places.
Beside these alternatives, there has been cyber space (i-campus) for reading materials, hand in homework and questions on every classes of the university. After we did set up the facility, we used the new system for our own linear algebra class. We tried to put up more teaching materials on the web before the class, and brought some Word, PDF or PPT file of each lecture. Then we precede our lecture on the lecture file, we did fill the gap and write proofs on it. We could show and use every possible resource for the lecture. And all of our activities in the class were saved for students. Students could review the parts that they did not fully understand in the class over and over again after the class. We gave some incentive for good questions and answers from students for raised questions. After two weeks of teacher¡¯s help, students were getting involved to answer for the most ofquestions.

Questions and answers, Whiteboard, PDF file with marks in a classroom
Visualization materials, JAVA tools to be used
(PC program to save and review lectures)
4. How it changed our Linear Algebra class?
This way of learning process and facility may not work well with some math courses, but our linear algebra course was quite well matched with this new learning environment. Because we could visualize concepts of linear algebra and use tools to calculate determinant and eigenvalues of large-sized matrices in the class just after the hand calculation of small-sized matrices. Students asked more questions, and were actively involved in this learning process, and students were eventually being able to answer most of questions each other. We finalized those answers in the class. Some good questions of their own were used for the midterm exams problems as well. This activity finally made big changes on the performance of students. They began to make active participation during the class. As a consequence, student¡¯s satisfaction and their performance in the final exam were far better than any other classes. But we all know this new system don¡¯t do all works on behalf of us. We have to design the whole lectures first, and then we must be able to manage each lectures and extra works of students.

Analysis :
We wrote our lecture note for each class, and then we made some of multimedia contents of it and put it on the web (i-campus of Sungkyunkwan University http://gingko.icampus.ac.kr/ Icampus ). So students can study before the class and ask any possible questions each other. We checked those activities before the class, and give some answers to finish up the discussions on the web. Then we go to the classroom and turn on the system, and explain some important ideas from those discussions, then start the lecture with PDF or PPT file of our lecture note. We could write and mark on it. And whenever we need, we could use every possible internet resources to help student¡¯s understanding and show any references needed. After the class, any part of our lectures that students should know are saved on the web, so students can review any part that they want to review. Obviously, students cannot miss any part of class work, and almost all questions that were raised through the class could be answered by each other or by teacher. They learned by themselves, so they did not forget. We found that students could not find anyone to blame in any case. The verification was appeared at the course evaluation after the semester. Since then, it was known among students that this course is much harder than other similar classes, but they can learn more. So more students are trying to get into the class even though their grade can be lower because of the competition. And the course evaluations of these classes were the best in the whole university a couple of times. The following was an example of the Teaching evaluation that showed the change. Since then, most of the student evaluation on our type of linear algebra class was higher than 90. That gave our appreciation on our students as well..

In Jan. 2005, government also announced that they would like to make Korea to be a Hub of e-learning. In order to do so, they decided to invest KRW417,100,000,000 – in the year 2005 for IT industry and schools. This investment will also effect on our educational environment at college as well. We believe our new educational environment of college will be effectively used over all level of education without much cost.
6. Conclusion
What we did try in our new lecture
room environment was not ¡°lecture - memorization – tests¡±, but it was
¡°visualization (intuition) - trial - error - speculation –
explanation¡±.
From the first, our goal was to improve the
quality of our college education. We did put our course materials
on the web before the class as much as we could, so students knew what to do in
the earlier stage, and asked questions before the classes and discussed them as
well. When we met the class, we cleared up those questions first, and did
precede regular off-line lectures on white and black board type tablet PC. We
could go anywhere when we need, for more on line information. We could visualize
any possible mathematical concepts, and do large-size calculation to verify
facts and get new conjectures. And all these activity on tablet monitor were
recorded as clear as original lectures with sound. So students could review any
parts that they missed whenever they need right after the
class. Finally we made them to explain
by themselves what they could do. http://matrix.skku.ac.kr/WebLA/index.html .
In our learning process, students found professor¡¯s roles as not only a teacher but also an Innovator, Mentor, Facilitator, Coordinator, Director and Producer. We found that student¡¯s satisfaction and their performance were much better than before. We finally found we now lives in future educational environment already.
Thank you!
