- 中文摘要: The purpose of this 1-year study was to investigate the improvements in problem-solving ability and cognitive learning achievement or technological literacy, with regard to the issue of waste disposal, using a problem-solving approach guided by classroom and web-based instruction. The important technological and social issues for different educational levels were identified in a previous study. Waste disposal was chosen as the topic for this study. A nine-step problem-solving strategy was used for the development of instructional materials for elementary (5th grade) and junior high school (8th grade) levels, both in classroom and website environments. A pre-test/posttest design was adopted to evaluate the effectiveness of and differences between the two conditions. The results showed that overall problem-solving skills improved in the elementary school classroom instruction group, and that waste-disposal knowledge improved in the junior high classroom instruction group. No significant change was found in either the overall problem-solving skills or waste-disposal knowledge of web-based instruction groups at the two educational levels. This study encourages efforts to integrate problem-solving training and technological literacy education, but repeated practice with different topics (or issues) is required for significant results. The web-based instructions designed for this study were unsuccessful. Student's limited competency in word processing and unfamiliarity with interactive computer instructions may have been the key reasons for this failure.
