碩士 === 國立中央大學 === 網路學習科技研究所 === 102 === To improve science literacy, high school students’ science reading and writing has been highlighted. To facilitate high school students’ learning outcomes derived from science reading and writing, this study aimed to develop the Online Science Reading and Writing System (OSRWS). In the OSRWS, Student science reading and writing are integrated as the process of online inquiry. After the development of the OSRWS, this study also conducted system evaluations of the OSRWS. A total of 61 10th graders participated the system evaluation of the OSRWS. With a quasi-experimental design, 29 students were randomly assigned to the experimental group, while 32 students were assigned to the control group. Before the conduct of this study, both the students in the two groups were asked to write science-related essays. Then, the students in the experimental group were asked to write science-related essays with the OSRWS during two days (16 hours), while the students in the control group were asked to write essays freely during the two days. The students in the control group expressed satisfactory perceived usefulness and ease of use of the OSRWS. Also, they expressed high willingness to use the OSRWS. The students in the experimental group obtained significantly higher scores on their essays than those in the control group did. Besides, it was also found that the low achievers in the experimental group obtained significantly higher scores than their counterparts. Implications on educational practices and system refinement are also discussed in this study.
