Developing a Situated Learning Website for Learning Spectrum Analyzer and its Instructional Effectiveness Analysis
The purpose of this research was to investigate the learning effectiveness of situated environment based e-Learning system for studying Spectrum Analyzer both on cognitive and psychomotor learning among different prior knowledge students. A website of learning Spectrum Analyzer was developed to apply on experimental instruction and a test was given to evaluate learning effectiveness and a questionnaire was given to test learning satisfaction. Thirty-one students were selected from Department of Applied Electronic Technology, National Taiwan Normal University as sample. The research method was used one-group pretest-posttest quasi-experimental research due to the limit of sample objects and devices. The results of statistical analysis with SPSS 19 for pretest, posttest of cognitive learning, operational performance and learning satisfaction were found as the following key points: 1.The situated based Spectrum Analyzer learning website can promote the learner effectiveness of cognitive learning. 2.The situated based Spectrum Analyzer learning website can guide learner's operation on Spectrum Analyzer correctly and decrease learning time. 3.The advancement of cognitive learning achievement of low prior knowledge group is better than high prior knowledge group on Spectrum Analyzer e-Learning, but the average score of high prior knowledge group is higher than low prior knowledge group. However, the difference of skill learning achievement between these two groups is insignificant, but the average score of low prior knowledge group is slightly better than those of high prior knowledge group. 4.The website interface design, content design, scenario design and overall impression were to the satisfaction of students.
