Designed as a survey research, it involved 50 respondents consisting of 3 experts/lectures, 5 teacher and 42 students who were selected by stratified sampling technique and random chance. Data were analyzed using SPSS Version 23.00 for Windows to test internal concistency using Cronbach Alpha. The results showed that all items in the questionnaire were valid and reliable, withan average high Cronbach’s Alpha realibility score (0.897 > 0.6) and each statement had a high score (0.784 to 0.890).

Abstract

According to Purwanto (2018), research instruments are tools used to collect data in research. The purpose of this study was to test a valid, consistent and reliable critical thinking instrument. In this study, critical thinking consists of five constructs, namely: (1) giving a simple explanation; (2) developing basic skills; (3) summarizing; (4) giving a more detailed explanation; and (5) deciding on the next strategy. The study was designed as a survey research with 50 respondents, consisting of 3 experts/lecturers, 5 teachers and 42 students selected through stratified and random sampling techniques. Data were analyzed using SPSS Version 23.00 for Windows to test internal consistency using Cronbach Alpha. The results showed that all items in the questionnaire were valid and reliable. The average Cronbach alpha reliability score is high (0.897 > 0.6) and each statement has a high score (0.784 to 0.890). Therefore, these figures indicate that this study has developed a critical thinking instrument.
