Profile of logical reasoning ability of student in solving organic chemistry problems

Abstract

This study aimed to analyze the students' logical reasoning ability with their expertise works with organic problems. The explanatory research design was used in this study. This research was conducted on students in the Chemistry Education Study Program at one of the public universities in Papua. The research used TOLT and basic concept of Organic Test as the instrument. Data collected using a questionnaire and analyzed using the correlation statistic. Based on the results of the research, the proportional reasoning ability of Chemistry Education students has the largest percentage of 75% and the lowest is probability reasoning of 46.88%. For the logical reasoning category, it is known that the logical reasoning abilities of chemistry education students include three (3) categories of logical reasoning, namely formal thinking skills with the highest percentage of 75%, while concrete thinking skills and transitional thinking skills each are 12.5%. The results showed that the average solve problems of ability of the basic concepts of Organic Chemistry was 69.4% of students of Chemistry Education. It was concluded that Chemistry Education students had satisfactory performance in the test of the basic concepts of Organic Chemistry. Based on the results of the correlation test analysis, it is known that the correlation coefficient (r) between logical reasoning ability and the ability to solve problems of the basic concepts of Organic Chemistry is 0.833 (p = 0.000). The results of this study are recommended to be information for lecturers of organic chemistry to be able to make improvements in learning Organic Chemistry. In addition, for students to be able to develop their logical thinking skills to help them in solving an Organic Chemistry problems.
