Abstract

The aims of this study are: (1) to investigate the level students’ critical thinking skill on living things and environmental sustainability theme, (2) to examine the critical thinking difference among different gender, learning styles, and students’ motivation, and (3) to investigate the correlation between students’ critical thinking and students’ motivation. This research was conducted due to the importance of critical thinking evaluation or measurement to get current skill description as the basic information to improve critical thinking in junior high school. The method of this study was descriptive research method. 110 students from three junior high school in Kuningan was tested with Science Virtual Test on Living Things and Environmental Sustainability Theme for 9th Grade as the measurement tool of critical thinking based on Inch critical thinking elements, and are given learning style questionnaire and science motivation questionnaire. Generally, the mean scores on six elements and overall critical thinking score from descriptive statistics shows a moderate critical thinking attainments level, with the range 43.33  score 69.75, while other two elements shows low critical thinking attainments level (score  43.33). At significant level 0.05 there is no significant difference between male and female, and also there is no significant difference among visual, aural, read/write, and kinesthetic learning style in critical thinking, while significant difference is founded on three different students’ motivation (Low, Moderate, High) groups on four critical thinking element skills. Hence to support the tendency, the correlation test is conducted. The correlation test shows there is no correlation between critical thinking and students’ motivation (r = 0.155, p = 0.81).

Abstract

An efficient way to improve the quality of education in critical thinking is developing the better tests. The test has been shifted towards the use of computer-based procedures. Lack of specific topic of critical thinking tests in science and the advanced of technology made the researcher intended to develop and validate a test to measure students’ critical thinking in the matter and heat topic based on computer for seventh grade junior high school. Generally, the process of developing and validating the test consists of 5 steps: (1) content analysis; (2) constructing multiple choice items; (3) readability test and expert validation; (4) limited tryout; and (5) larger application. Based on larger application, it is obtained the reliability value, difficulty level, discriminating power and distractor quality. The method that used in this research was descriptive. The subject was 117 students of public Junior High School in Kabupaten Bandung. The instrument validation resulted 30 items that represent 8 elements and 21 sub-elements to measure students’ critical thinking based on Inch in matter and heat topic. The instrument is further called as Science Virtual Test Matter and Heat (SVT-MH). The alpha Cronbach (α) is 0.642 which means that the instrument is sufficient to measure students’ critical thinking matter and heat topic. The result also shows the profile of students in critical thinking is 73% categorized as ‘moderate’, while students respond the positive impression towards the use of SVT-MH.KeywordsScience virtual test, critical thinking, matter and heat, readability test, validity, reliability, students’ impression
