1 Narrowing the Digital Generation Gap e-learning Program for Teachers on Water Environment Education Hsin-Yu Shan Department of Civil Engineering, National Chiao Tung University Jen-Gaw Lee National Center for High-Performance Computing Frances Su Microelectronics and Information Systems Research Center, National Chiao Tung University Abstract This paper describes the lessons learned from a very large scale e-learning program for on-the-job training of school teachers on water environment. School teachers are not as familiar with e-learning as their students due to the generation gap created by the rapidly growing information and communication technology. This program tapped into the potential of using e-learning for continued education of more than 2, teachers who are required by the Ministry of Education to take 2 hours of courses each year. Up to date, thousands of teachers have completed the e-learning program. Valuable information is obtained on the behavior and feedback of the trainees. It shows that younger teachers and those with a background in natural science are much more willing to take part in the e-learning program. In addition, teachers interact very little with each other and the instructors. Nevertheless, the quality and the convenience of the water environment training program inspired most of the participants to accept e-learning as the better way for continued education and to join similar e-learning programs in the future. 1 Introduction Environmental awareness and knowledge is considered as an important aspect to be incorporated into the learning of all subjects in all levels of schools in Taiwan since the Earth Summit in As the school education reform which integrate various aspects into traditional subjects such as language and mathematics for the entire 9-year period of compulsory education, school teachers has to obtain additional knowledge and skills on topics such as water environment. On the other hand, school teachers are required by the Ministry of Education to take 2 hours of courses as on-the-job continued education. As a result, it creates an excellent opportunity for the government to educate the teachers on water environment and sustainable development as the first step toward nurturing a new generation of citizens of high environmental awareness and capability to act. However, the training more than 2, school teachers in the entire nation with good instructors and high quality course contents is a formidable task through traditional face to face learning. Obviously, the delivery of high quality water education training courses to thousands of teachers all over the island in a short time can rely on no other method than distance learning. Under the leadership of Taiwan International Institute for Water Education (TIIWE), a plan for the comprehensive water education training program was devised and the project team is formed. The team consists of TIIWE, Graduate Institute of Environmental Engineering of National Taiwan University, Environment Conservation Center of National Taiwan Normal University, ITS EduMedia Studio of Microelectronics and Information Systems Research Center of National Chiao Tung University (NCTU), China-Times Cultural and Educational Foundation, and National Center for High-Performance Computing (NCHC). The training program is co-sponsored by the Ministry of Education, the Environmental Protection Agency, and the Water Resources Agency. The target participants of the water education training

2 program described in this paper are the 2, teachers from elementary schools, junior and senior high schools, and vocational schools. During 24, 25, 26, a total of 5,617 people registered to participate and 3,94 participants finished at least one of the modules. The total number of modules taken by the participants was more than 15,. The participants were awarded certificate for the modules and hours they completed. 2 The e-learning Program For the first two years of the project, a total of hours of on-line courses were produced. In addition to the on-line courses, the participants could take the optional one day face-to-face course which includes half day of classroom discussion and half day of field trip to enhance their learning. The instructors include university professors and senior officials of government agencies. The overall course structure and classes are listed in Table 1.

The learning management system (LMS) is developed by ITS EduMedia Studio and fully conforms to SCORM standards. The courses were produced using Microsoft Producer [1] to display video of lecturing and Powerpoint presentation at the same time. Figure 1 is a screen shot from the on-line lecture on Earth Environment and Sustainable Development. According to the course content, each 1.5-hour course was divided into sections of about 15 to 2 minutes which is the time span the participants can maintain highly concentrated. This short time section also allowed the participants to fully utilize fragmented time between their classes and other activities in schools or at home. All videos

Microsoft media servers were deployed to provide video 15 Kbps course video streaming [3] to participants computers which is connected through TANet (Taiwan Academic Network) or ADSL. Figure 1 Sample Screen of the On-Line Course Table 2 Number of Participants of the elearning Program Registered Completed Dropout Rate 46.2% 26.9% 29.1% 19.9% In order to enhance the achievement of learning, the following policies are designed and applied: 4 courses are organized into 4 modules, each module contains 1 courses. Each student has to enroll for at least 1 module. The certificate is only awarded to the participants after completion of modules. For each category Each week two new courses were put on-line. Each course is open for 2 weeks. Furthermore, the participants were required to complete a course evaluation survey before their course hours was recorded officially. 3 Result of the Training Program A total of 4 terms of e-learning were delivered from 24 through 26. The numbers of participants registered and completed at least one module are listed in Table 2. From the age distribution of participants shown in Fig. 2, it is obvious that this program attracts much higher percentage of younger teachers [4]. About 8% participants are between 2 and 4. 45% 4% 35% 3% 25% 2% 15% 1% 5% % Participant Whole nation < >5 Figure 2 Comparison of Age Distribution of the Participants and All Teachers in Taiwan 6% 5% 4% 3% 2% 1% % 52.2% 5.8% Elementary school 18.7% 24.4% Junior high school 6.4% Senior high school 17.% 3.% 7.8% Vocational school 1.5% University.4% Kindergarten Participant Whole nation 3.4% Intern teacher Figure 3 Distribution of Participants Background 14.5% Others

4 The distribution of the backgrounds of the participants is shown in Fig. 3. Among the participants, 52.2% are elementary school teachers, 18.7% are junior high school teachers, 6.4% are senior high school teachers, 3.% are vocational school teachers. About 14.5% of the participants were public servants, students, and general public. It is interesting to compare variation of the participants specialized area with their purpose. As shown in Fig. 4, initially most participants are teachers in natural science, but as time went on, more and more teachers in other specialized area join the program. It is also important to note that approximately 82% of the participants never participated in any education or training programs on water environment and 68% had no previous e-learning experience. However, most of the participants are already frequent computer users before the program where more than 8% of the participants use computers at least 5 hours per week (Fig. 5). 9% 8% 7% 6% 5% 4% 3% 2% 1% % Language Math Natural Science Social Science General Education Applied Technology Art Business Other Figure 4 Distribution of Participants Specialized Area Intensive (>2 hr@week) Frequent (1-2 hr@week) Often (5-1 hr@week) Little (< 3 hr@week) Seldom (< 1 hr@week) Figure 5 % 5% 1% 15% 2% 25% 3% 35% 4% Intensity of Computer Usage of Participants Excellent Good Fair Rather unsatisfactory Very poor Interaction Model AV Quality Web Site Design e Learning model % 1% 2% 3% 4% 5% 6% Figure 6 Rating of the elearning Program and the LMS Platform The effectiveness of learning was assessed by results of (1) pretest and post test and (2) after course quiz. The test results showed that the improvement of participants understanding of important concepts varies but the highest percentage is close to 2%. On the other hand, the results of the after course quizzes showed an average correct rate ranged from 51% to 88% as the breadth and depth of the courses and the difficulty of quiz questions vary. Furthermore, the design, organization and management of the program were evaluated with compulsory participant survey. As shown in Fig. 6, the participants give the e-learning program and the LMS very good rating. However, currently the quality of video is as satisfactory due to the limitation of the bandwidth on the users end and can be easily enhanced in the future. The most critical issue is that the interaction among the participants and/or with instructor is significantly

5 less satisfactory. The limitation comes from the nature of asynchronous on-line course and the browser. The participants interacted with the instructor and among each other through discussion board and file sharing, which is far from spontaneous as face to face discussion. This particular result points out a very specific aspect for future improvement. About 97% of the participant expressed they would like to join on-line learning program on other subjects. In general, although about 68% of participants had their first experience in e-learning by joining this program and become supporters of e-learning. Considering the difficulties of many of the participants had with the software, operating systems, hardware, and internet connections at the start of the courses, the quick acceptance and preference of e-learning programs are quite encouraging. 5 Lessons Learned There are several important lessons learned form the user behavior and their responses to the program: (1) User habit is not easy to change The participants simply shut down the computer without clicking and closing the on-line course window such that the system could not record the logout time. There are a lot of requests by the participants asking servicing staff let them pass courses claiming that they ve done watching it but not getting the LMS to show valid records. Good habits are not easy to establish. (2) Service manpower loading can be heavy The on-line course had a rough start since most of the participants did not have any experiences such that they run into problems with their computer operating systems, Internet browsers, or internet connections. The participants report their difficulties with the error report function, and the technical support team helped them solve their problems through instructions over the phone or . For 24 project period, 384 error reports were received, among which 16 reports were posted in the first week. Two LMS engineers were responsible to solve all the technical problems. Almost all of the technical difficulties were resolved quickly and some of them become the content of the website s FAQ. As time went on, technical problems such as internet, operating system, and browser decreased. However, the loading of two staff members who served as teaching assistants remained as heavy as the start. Participants have all sorts of problems regarding asking register after closing date, how the course hours was recorded, how the certificate can be awarded, requesting for make up classes, and questions of the content of the courses or quizzes. The program allows the participants to login even after they had finished the courses in order to let them interact with each other and form a community among themselves. However, this requires the staff constantly monitored the website and answered questions. Not surprisingly, there is a distinct shift of user behavior over time. Those who join earliest and most interested in water environment are most active all through the term including Saturdays and Sundays (Fig. 7). More over, they logged in the system weeks after the end of the term for discussion (Fig. 8). The later participants were much less interested and much less active, which in a way relieved some pressure on the staff. Login Count.

The knowledge transfer and time management is significantly better than interaction. The statistics shows even worse. There were only 266 discussion subjects posted by the participants on the discussion board. The project manager and teaching assistants spent a lot of effort in responding the messages and keeping the discussion alive. These messages only got 1,211 responding posted messages and were read 45,219 times. In other words, most participants never actively interact with any fellow participants. Figure 1 shows the categories of discussion subjects posted. Most of them are related to the courses or environmental issues. (4) Expanded use of the program is limitless A lot of participants login the LMS and play back the on-line course in the geography, earth science, and social science class they are teaching and directly let the students watch the on-line course. Moreover, the courses have been rearranged to become formal on-line courses delivered in the universities and community colleges. Government agencies also requested the project team to reorganize the courses to establish training programs for public servants and volunteer workers. 6 Conclusion The water education innovative project is the

7 pioneering in Taiwan. Vital experiences regarding the design and management of the program, the LMS, the on-line courses, and behavior of the learners were obtained. The final phase of the projects will be carried out in 28. Fifteen new on-line courses will be developed and delivered, including 5 delivered in English to establish a module on Asian water environment. In addition, experiment with co-life on-line conferencing system to facilitate interaction will be incorporated into the program. The system will be used for case history discussion host by the instructors for experimental purpose. This system developed by NCHC allows 6 people to joint a discussion session simultaneously with full video and file presentation/exchange capacity. Application of new technologies will continued to be explored with the support from NCHC and other partners.
