摘要

Teaching and learning in 21SUPth/SUP Century is recommended to achieve higher order thinking skills (HOTS), such as critical thinking skills. However, the availability of instruments of critical thinking skills at senior high school level is very limited. This paper discusses the development of a critical thinking skills instrument on the topic of electricity, dynamic electricity and static electricity for senior high school students. The development procedure consisted of seven stages. The subjects in present study consisted of three experts for content, construct, and language assessment, three students for readability test, and 70 high school students for validity and reliability tests. From the results of Pearson correlation coefficient and Cronbach alpha value, there were 4 indicators (out of 6 indicators) with 32 items were valid and reliable. Thus, the critical thinking instrument of electricity topic may be used to measure students' critical thinking skills at senior high school level.
