Implementation of test instruments to measure students’ critical thinking skills on sound wave

Abstract

This research aims to determine the implementation of test instruments that measure students' critical thinking skills on sound wave subject. The test instrument which is used in form of essay questions consisting of 12 questions containing 4 indicators and 9 sub-indicators of critical thinking skills proposed by Ennis. The instrument used has been declared valid and reliable so that it can be used for implementation testing. The instrument testing stage was carried out involving 249 high school students from 4 schools in Bandung city with quantitative method. The results of the hypothesis test with a difference of 2 average values show that the instrument used can differentiate between learning processes that train and do not train critical thinking skills, where the zcount value of 10.17 is greater than the zvalue of 0.05 so it can be concluded that the research hypothesis is accepted. To measure the identification of similarities in learning models that train critical thinking skills using the results of the one-way Anova test, where the significance value of 0.35 is greater than 0.05, so it can be concluded that the research hypothesis is accepted. Next, to assess the relationship between critical thinking skills and understanding of teaching material, use the Pearson Product Moment correlation test, where the degree of closeness of the relationship between critical thinking skills and understanding of teaching material is shown by the correlation coefficient value, namely 0.51. This means that the degree of relationship between critical thinking skills and understanding of teaching material is included in the high criteria.
