碩士 === 中原大學 === 教育研究所 === 103 === The purpose of this study is to illustrate the process of applying instructional representation in Science and Technology and explore its effect on the learning for the eighth-grade students. At the end of the study, the study is going to discuss the problems and the solutions. This study was conducted through the action research method. Thirty eighth-graders were taught by using a variety of instructional representations in the Science and Technology teaching.The study was carried out during the first semester in 2014 (from September to December, 2014).The curriculum mainly focused on the following five topics: experiment and measuring, substances, waves, sounds and optics. Qualitative data, like teaching videotapes, teaching reflection notes, interviews and meeting minutes were collected and analyzed. Through the interviews, the study found out the process of students’ knowledge reconstruction. Students connected the content of the videos they watched in class with the scientific terms. Students could infer the whole concepts from recalling the video. Thus, pictures played an important role in recording key events; texts helped students to understand precisely. The main results of the study are as follows. 1. Massive videos were employed to build the microcosmic concept of substances and to present the features of sounds. Schematic diagrams and actual pictures were demonstrated in the unit of optics. Texts, pictures and videos were even integrated in PowerPoint in the unit of temperature. 2.Students are deeply impressed by the usage of videos. Asking questions could help them to decode the information of the pictures. Texts could be illustrated by pictures and videos. 3.A variety of instructional representations could be presented by PowerPoint.The usage of graphs and texts gave students a clear concept for number calculation. It is suggested that teachers may use different teaching methods to present instructional representations. The action research can be used in other subjects of science area. Finally, the instructional representations used in the study can also be applied to other classes to enrich the samples.
