Abstract

The importance of developing critical thinking skills (CTS) is claimed as a major education purpose.  Recently, enhanced learning has been conducted to promote students' CTS through study on certain topics (specific domains). Based on the numerous studies on CTS, there is a need for an assessment instrument to test students' CTS.  This research aims to develop an instrument of CTC on mechanical wave topics for senior high school students. The instrument consists of seven essay items and one forced-choice item, tested to 45 students of class XI high school in Malang. The validity test obtained an excellent Cronbach alpha coefficient of ? = 0.717. There was also an inter-rater test for the scoring guideline reliability using the intraclass correlation coefficient (ICC) with high reliability results (? = 0.909). The results of this study indicate that the instrument is qualified to be used to measure students' CTS on mechanical wave topics.

Abstract

The weakness in students’ scientific argumentation, particularly in providing evidence-based arguments, has become a significant concern in education. This study aims to assess students’ scientific argumentation skills specifically on the topic of static fluids. The survey was conducted with 78 twelfth-grade students from private high schools in East Java, Indonesia, who had previously studied this topic. A scientific argumentation test instrument, consisting of an essay format with five questions, was employed to collect data. The data were analyzed using descriptive statistics, followed by a classification based on static fluid subtopics and the level of scientific argumentation skill. The results indicated that the average student score was 10.60, which falls within a low category. Additionally, the findings revealed that a substantial number of students failed to sufficiently use evidence to support their arguments. These outcomes highlight the need for instructional strategies that better develop students’ scientific argumentation skills.DOI: 10.17977/jps.v12i32024p104
