| Summary: | 碩士 === 國立臺北教育大學 === 自然科學教育學系碩士班 === 97 === This study applies an on-line tutor curricular system with ADDIE(Analysis, Design, Develop, Implementation, Evaluation)model to design six learning units about heredity. The participant is a seventh grader of junior high school. The main research questions are : (1) What are the teaching content and teaching procedure during applying the on-line-tutoring curricular system for student’s learning?(2) when we apply this system, what’s the interaction between the teacher and the student? (3) What is the effect about the learner understanding the concept of heredity?
The data collections of the first and the second mentioned of the three research questions are about the teacher’s teaching diaries to describe the teaching process and the interaction between the teacher and the student. The third of the three data source are the diagnostic pre and post tests which are adapted from this research, and those data are quantitative collection.
