【 摘 要 】

Critical thinking is skill and ability to use of risk taking creativity to make a decision and knowledge as a result, analysis and synthesis that, evaluation, to acquire, information search, to develop thinking, as an individual aware of his or her own thinking. The aim of this study is to develop the science virtual test to measure students' critical thinking on living things and environmental sustainability theme. The research method that is used in this research was descriptive research. The development of science virtual test item consist of five steps: (1) content analysis; (2) constructing the instrument (multiple choice) based on the elements of critical thinking by Inch; (3) validity judgment of the instrument by the expert; (4) legibility test of the instrument; (5) conducting the large field test. On the large field test was gained the results of validity and reliability of the test, difficulty index, discriminating power, and quality of distractor. The subjects of research were 8th grade students at International Junior High School in Bandung with 125 total of respondents. The coefficient alpha (α;) was 0.747, the reliability of the test was categorized as 'high' and value of RXY correlation was 0.63 which mean that the validity of the test was categorized as 'high'. These means that science virtual test can be used to measure student's critical thinking with a good consistency. It is expected for other researcher to take this description as one of the basic information to be considered in developing science virtual test for improving students' critical thinking by various kind of topic.
