The analysis of application of learning materials based on inquiry based learning and its effect on critical thinking skills of students in solving fractions problems

Abstract

Abstract Critical thinking skills are needed to improve mathematical abilities in 21st century. However, with the current learning model, showing students' critical thinking skills did not increase significantly. This study aims to analyze usage inquiry-based learning and find out their effects on students' critical thinking skills in solving fractions problems. Research design using research a mixed methods that is a combination of quantitative research and qualitative research. Research respondents from class 3 were divided into a control class of 22 students and an experimental class of 20 students. Data collection is done through observation sheets, tests, documentation and interviews. The results showed that after the implementation of inquiry-based learning, the percentage of students' critical thinking for the control class was a very critical of 0%, critical 9%, 45% for quite critical, and 46% for less critical and not critical. Starting while for the experimental class the results were very critical 25%, critical 50%, quite critical 15%, less critical 10%, not critical 0%.. The t-test score of the independent samples from the post-test showed that there was a significant difference between the control class and the experimental class with a sig (2-tailed) value of 0.001 (p = <0.05). It can be concluded that the application of inquiry-based learning can influences students' critical thinking skills in solving fractions problems.
