Abstract:
The goal of this research was to research, design, and develop a hypertext program for students who study biology. The Ecology Hypertext Program was developed using Research and Development (R&D) methodology. The purpose of this study was to place the final “product”, a CD-ROM for learning biology concepts, in the hands of teachers and students to help them in learning and teaching process. The product was created through a cycle of literature review, needs assessment, development, and a cycle of field tests and revisions. I applied the ten steps of R&D process suggested by Borg and Gall (1989) which, consisted of: 1) Literature review, 2) Needs assessment, 3) Planning, 4) Develop preliminary product, 5) Preliminary field-testing, 6) Preliminary revision, 7) Main field-testing, 8) Main revision, 9) Final field-testing, and 10) Final product revision.
The literature review and needs assessment provided a support and foundation for designing the preliminary product – the Ecology Hypertext Program. Participants in the needs assessment joined a focus group discussion. They were a group of graduate students in education who suggested the importance for designing this product.
For the preliminary field test, the participants were a group of high school students studying biology. They were the potential user of the product. They reviewed the preliminary product and then filled out a questionnaire. Their feedback and suggestions were used to develop and improve the product in a step called preliminary revision.
The second round of field tasting was the main field test in which the participants joined a focus group discussion. They were the same group who participated in needs assessment task. They reviewed the revised product and then provided ideas and suggestions to improve the product. Their feedback were categorized and implemented to develop the product as in the main revision task.
Finally, a group of science teachers participated in this study by reviewing the product and then filling out the questionnaire. Their suggestions were used to conduct the final step in R&D methodology, the final product revision.
The primary result of this study was the Ecology Hypertext Program. It considered a small attempt to give students an opportunity to learn through an interactive hypertext program. In addition, using the R&D methodology was an ideal procedure for designing and developing new educational products and material.
