| Summary: | 碩士 === 國立屏東師範學院 === 數理教育研究所 === 90 === The study was aimed to explore 4th and 5th graders at elementary school on the concept of battery. The subjects consist of 4th and 5th graders. A paper and pencil test was composed with twelve main concepts on battery and was administered firstly to investigate students’ alternative conceptions. And interview with two-tier diagnostic assessment instrument to check student’s alternative conceptions. These concepts on battery are：what are the materials of battery, how to produce electricity, whether or not battery can be produce electricity , construction of battery, differences of battery, load of battery, series and parallel connections of battery, opened and closed circuits, brightness of light bulb and the duration of use, electrolyte of a solutions. The qualitative data is further transcribed and analyzed to find students’ alternative conceptions.
The study will be implemented into three parts, they are
1. the use of paper and pencil test to collect students’ conceptions on battery;
2. interviews with students;
3. development of a two-tier concept diagnostic to explore a large scale sample.
The results show that the common alternative conceptions of battery using the paper-and-pencil test with two-tier diagnostic assessment can be categorized into 12 types. The most troublesome of those are differences of battery, load of battery. Therefore, we suggest in the teaching process that teachers should try to strengthen and integrate the various concepts via small group discussions or via hands on experiments to build up better understanding of the science concepts.
