Abstract

This research aims to determine the effectiveness of the PQ4R learning strategy on students' critical thinking skills and learning motivation. This research uses quasi-experimental research with a nonequivalent control group design. The population in this study was part of class XI MIPA at MA Negeri Kendal. Sampling was carried out using the cluster random sampling technique. The sample used in this research was 36 students of class XI MIPA 4 as the experimental class and 32 students of class XI MIPA 3 as the control class. The research results showed that the critical thinking skills t-test obtained a significance value (Sig.) 0.000 < 0.05, meaning there were differences in critical thinking skills between the experimental and control classes. Based on the results of the N-Gain test, critical thinking skills for the experimental class were 0.4418, and for the control class were 0.1483. The results of the t-test research on learning motivation obtained a significance value (Sig.) 0.001 < 0.05, meaning there is a difference in learning motivation for the experimental and control classes. Based on the results of the N-Gain test, the learning motivation for the experimental class was 0.3315, and the control class was 0.1529.  This research concludes that the effect of the effectiveness of using the PQ4R learning strategy on critical thinking skills and learning motivation in the experimental class is higher than in the control class.

Abstract

IMPLICATION OF MINI PROJECT ORGANIC CHEMISTRY EXPERIMENTS FOR IMPROVING ORGANIC CHEMISTRY CONCEPTAbstractOrganic Chemistry Practice is one of the courses in the chemical education department that must be taken by pre-service teacher of chemistry, still lack of mastery of students on organic chemistry concepts, requiring lecturers to be able to design the experiment in such a way so as to increase mastery of the concept of organic chemistry students in Organic Chemistry Practice. This study aims to apply the mini project model to the Organic Chemistry Practice so that it is expected to increase students' mastery of concepts in organic chemistry. The research was conducted using quantitative methods, its measuring conceptual change from the students from N-gain score. The results showed that there was an increase in students' mastery of concepts based on the% N-gain obtained. The majority of students are at a high criterion with% N-Gain> 70. The t test shows the significance of the implementation of the mini project model to increase students' mastery of concept concepts.AbstrakRendahnya penguasaan mahasiswa terhadap konsep-konsep  kimia organik, menuntut pengajar untuk dapat mendesain praktikum sedemikian rupa, sehingga dapat meningkatkan penguasaan konsep kimia organik mahasiswa pada Praktikum Kimia Organik. Penelitian ini bertujuan untuk menerapkan model mini project pada Praktikum Kimia Organik sehingga diharapkan dapat meningkatkan penguasaan konsep mahasiswa pada materi kimia organik. Penelitian dilakukan dengan metode kuantitatif, yakni mengukur hasil tes penguasaan konsep mahasiswa. Hasil penelitian menunjukkan bahwa terjadi peningkatan penguasaan konsep mahasiswa berdasarkan hasil %N-Gain yang diperoleh. Mayoritas mahasiswa berada pada kriteria tinggi dengan %N-Gain > dari 70. Uji t menunjukkan signifikansi pelaksanaan model mini project terhadap peningkatan penguasaan konsep mahasiswa.
