Abstract:
This research aims to create and develop an educational website on global warming and to find out its learning effectiveness, the number of learners of each chapter, and their degree of satisfaction. Research procedures began with the construction of the website by utilizing the program Visual Studio.NET. Its quality was then improved by 5 experts on the area inspecting its content appropriateness and the aspect of its educational technology. The site was tried out with a group of 30 people selected by means of purposive sampling, using pre- and post-testing. The research tool was composed of 20 questions with 4 multiple choices, assessing the knowledge on the issue, the data of which were analyzed by the t-test, and 11 satisfaction-evaluating questions with a rating scale of 4 levels, the results of which were illustrated in the form of percentage, mode and tabulation. The tables showed the number of visitors for each topic during 14-27 February 2005. The total number of the visitors used for data analysis was 70, derived from random sampling, presented in percentage. This research found that the respondents in the sampled group achieve significantly effective learning after their studying the webpage at .05, the satisfaction rate is in the high and highest level, the topic of the cause of global warming gains highest attention, and 14.29 per cent of all the visitors are interested in every topic. Therefore, a conclusion can be reached that web-based learning providing the knowledge on global warming is appropriate for rendering Internet users' understanding of global warming. Recommendations for ultimate benefits in the future are that a section of a nature conservation club should be added to the web board in order to increase awareness and participation in solving environmental problems, and a relevant governmental unit should involve the publicizing of environmental issues for long-term advantage.
