Abstract

The teaching and learning process in the classroom has not been able to arouse students 'learning motivation so that the learning motivation of students is not maximal, students' learning motivation is not maximized, seen from the learning process there are still students who have not been able to focus their attention and concentration on learning, so that only a few participants students who are active in learning. In addition, there are still many students who are not confident, do not dare to ask questions and when doing group presentations not all students dare to speak, only rely on other friends. The research approach used is quantitative with the type of quasi-experimental research, the research design used is Pretest-Posttest Non-Equivalent Control Group Design. The study population was all students of class 10th Senior High School 1 Peusangan and Senior High School 2 Peusangan, amounting to 252 people. The sampling technique used was purposive sampling, the sample in this study consisted of 140 students. Instruments to measure motivation using a questionnaire in the form of pretest and posttest questions. Data analysis consisted of normality test, homogeneity test, N-gain test, paired sample t-test and independent sample t-test, at a significant level of 0.05. The results showed that there were differences in the learning motivation of students in the experimental class and the control class on environmental pollution material in class 10th Negeri Bireuen district.

Abstract

The learning process only focuses on the material by memorizing concepts, students do not use LKPD to do practical work optimally, so the biology learning process in schools does not encourage students to practice critical thinking skills. This study aims to improve students' critical thinking skills by using the PBL learning model combined with STEM-based worksheets on environmental pollution conceptin class 10th SMA Negeri Bireuen district. The approach used is experimental design, the method used is quasi-experimental, with a pretest-posttest design non-equivalent control group design. Population in class 10th IPA SMAN 1 and SMAN 2 Peusangan designed 252 people. The sampling technique used was purposive sampling technique. The research sample was 140 students. The number of samples in the experimental class was 71 people and 69 people in the control class. The instrument used was a reasoned multiple choice question accompanied by a rubric. The data analysis used was n-gain and independent t-test. The results showed that the critical thinking skills obtained was 0.93, with an increase in class critical thinking skills including the high category. The results of the independent sample t-test obtained Sig. (0,000) α (0.05) then Ha is accepted, so it is suggested that there are differences in the critical thinking skills of students between the experimental class and the control class on environmental pollution material in class X SMAN Bireuen. The implementation of PBL learning model combined with STEM-based LKPD can improve students' critical thinking skills on environmental pollution material in class 10th SMA Negeri Bireuen Regency.
