Critical Thinking Embedded Essay Test

The purpose of the study was to determine the effectiveness of the Guided Inquiry-based Student Worksheet (LKPD). The method used was a quasi-experiment with the one group pretest and posttest design. The population in this study was the students of grade XII IPA at SMA Negeri 2 Painan for the academic year 2020/2021. The sample in this study was the students from class XII IPA 1 as the experimental class and XII IPA 4 as the control class chosen by using the purposive sampling technique. The instruments used were observation questionnaires, product validation sheets, teacher and student practice sheets, and evaluation questions based on the critical and creative thinking indicators. The results of the analysis of pretest and post-test evaluation questions obtained that the mean of N-gain was 0.4 for critical thinking and Ngain was 0.5 for creative thinking. These two thinking skills had moderate N-gain scores. The results of the critical thinking t test showed that t arithmetic (0.036) < t (0.05) and creative thinking skills t test showed that t arithmetic (0.000) < t (0.05). Thus, it indicates that guided inquiry-based LKPD are effective for improving the students’ critical and creative thinking skills.

This study aims to determine the effectiveness of PBL-based LKPD. The method used was a quasi experimental with a posttest only control design. The population in this study were the students of grade XI MIPA SMAN 6 Merangin for the 2020/2021 academic year. The sample in this study was the students from class XI MIPA 3 as the experimental class and XI MIPA 4 as the control class chosen by using the purposive sampling technique. The research instruments were observation questionnaires, product validation sheets, practicality sheets for teachers and students, and evaluation questions based on critical and creative thinking indicators. Results of the analysis of evaluation questions showed that the mean scores of the critical and creative thinking skills of the experimental class students were higher than the con trol class. The mean scores of critical and creative thinking skills in the experimental class were 73.21 and 73.79. Meanwhile the mean score in the control class were 54.06 and 58.94. The results of the t-test of students' critical thinking were (0.000) < t (0.05) and creative thinking skills were (0.001) < t (0.05). Thus, it indicates that PBL-based LKPD is effective for empowering students' critical and creative thinking skills.

“…Critical thinking skills are scored based on each assessment rubric, and the number of scores obtained is calculated. The rubric for scoring critical thinking according to Zubaidah (2015) is shown in Table II.  Some of the concepts are correct and clear  Some of the descriptions of the answers are correct and clear but the reasons and arguments are not clear  The flow of thinking is quite good, some are interrelated  Grammar is quite good, there are spelling errors  Most aspects that seem correct Source: (Zubaidah S. , 2015) Posttest results were analyzed by using the Ermayanti (2016) formula:…”
