| Summary: | 碩士 === 國立臺中教育大學 === 科學應用與推廣學系科學教育碩士班 === 98 === We employ the content analysis method and 5E learning cycle to analyze the differences of electromagnetics unit activity design contained in four published versions of textbooks of Nature Science and Life Technologies. We utilized the Presentation Analysis Table of Units Related to Electromagnetics Concept, the Process Skill Item Analysis Table of Unit activities Related to Electromagnetics Concept, and the 5E Learning Cycle Item Analysis Table of Unit activities Related to Electromagnetics Concept. We analyze the differences in the distributions of electromagnetics concepts and electromagnetics unit activity design contained in the textbooks. The main results of the study are listed as follows. Each version contains an equal amount of electromagnetics concept units. By the order of the used percentage of the process skill classifications, the induction and deduction skills are the highest. The second to fifth order are the communication, the organization and correlation, the observation concepts, and the comparison and classification skills, respectively. The layouts of the electromagnetics activity units of the surveyed four versions are consistently organized with the 5E learning cycle.
