The purpose of this research are to knowing the differences of critical thinking skills using interactive module photoelectric effects  with printed module, describe the improvement of students' critical thinking skills after the interactive module is applied, describe science process skills in students who use interactive module of photoelectric effects, and knowing student responses to the use interactive module of photoelectric effects. The study was conducted in Natar 1 Public High School, in the even semester 2018/2019 academic year with research design nonequivalent control group design.The research instrument used was a questionnaire (questionnaire), Student Worksheet (LKPD) along with observation sheets and test questions. Data collection techniques were carried out by test techniques, questionnaires and LKPD contents. The data analysis technique of critical thinking ability is done by normality test, homogeneity test and N-gain. The data analysis technique of science process skills is done by calculating the average grade of the class then adjusted to the index classification table of science processes. Hypothesis testing is done by Paired Sample T Test and Independent Sample T Test. The results of the study show that (1) the application of the photoelectric effect interactive module is able to improve students' critical thinking skills, this is seen from the N-gain value and paired sample t test results, 2) there are significant differences in critical thinking skills between students who use interactive modules with printed modules, this is seen from the differences in the n-gain values of both classes and the results of the independent sample t test, (3) the value of students' science process skills is 82.6 with a high category, and (4) students gave a positive response to the utilization of the photoelectric effect interactive module.

In learning mathematics, students are still found to have difficulty in understanding and developing critical thinking skills. Therefore, the purpose of this study is to determine the significant influence of the Problem Based Learning model assisted by concrete media on the ability to think critically mathematics in grade IV in elementary school. This research was a quasi-experimental study with a non-equivalent control group design. The population of class IV SD as many as 293 people. The sample was determined by cluster random sampling technique. The sample in the experimental group was 32 students and the control group was 30 students. Data used as a test method in the form of a subjective test (description). The data obtained were analyzed using the t-test analysis technique with the polled variance formula. The results of data analysis were obtained (t-count = 4.021> t-table = 2,000) at the significance level of 5% (dk = 32 + 30 - 2 = 67) which means that there was a significant difference in the ability to think critically mathematics between groups being taught with the model of Problem Based Learning with media aids Concretely with the group learned using conventional learning models in class IV elementary school. It can be concluded that the Problem Based Learning model assisted by concrete media influences the ability to think critically mathematics in class IV. The results of this study can be used as input for teachers to choose various learning models in teaching.

Pelaksanaan penelitian ini dimaksudkan untuk mengetahui apakah dalam mengaplikasikan model Problem Based Learning dapat meningkatkan keaktifan dan keterampilan berpikir kritis siswa. Subjek penelitian yang digunakan ialah siswa kelas IV SD Negeri 2 Bojong yang memiliki jumlah 23 siswa, terdiri dari 15 siswa laki-laki dan sisanya perempuan berjumlah 8 siswa. Jenis penelitian yang dipakai ialah Penelitian Tindakan Kelas jenis Classroom Research dengan menggunakan model Kemmis & McTaggart. Pelaksanaan tindakan kelas ini diterapkan sejumlah 2 siklus, yaitu pra siklus, siklus I, dan siklus II. Per-siklus terdiri dari 4 tahap, yakni perencanaan, pelaksanaan tindakan, pengamatan, dan refleksi. Penelitian dilakukan pada semester II tahun ajaran 2020/2021. Pelaksanaan teknik penghimpunan data menggunakan tes dan non tes, sedangkan instrumen penelitian memakai soal uraian, lembar observasi, dan rubrik. Teknik analisis data yang digunakan oleh peneliti yakni teknik deskriptif komparatif. Hasil penelitian pada kondisi mula-mula atau pra siklus, keaktifan yang dicapai siswa terhitung 37,93%. Siklus I terhitung 60,82% dan pada siklus II mengalami kenaikan menjadi sebanyak 76,02%. Sedangkan saat siklus I, KKM yang dicapai atau siswa yang sudah memenuhi syarat berpikir kritis diakumulasikan dengan rata-rata sejumlah 63,78 dan pada siklus II siswa yang telah berpikir kritis meningkat dengan rata-rata 82,30. Oleh sebab itu, dapat dicapai kesimpulan bahwa keaktifan dan keterampilan berpikir kritis bisa ditingkatkan dengan cara menerapkan model Problem Based Learning.

Implementation of learning in class 11th MAN 1 and MAN 2 Banda Aceh City Students only get information without going through discussion activities, students who are not brave enough to express ideas or ideas, so that students are not trained in using their critical thinking skills. This study aims to determine the improvement of students' critical thinking skills through the application of the STEM-based discovery learning model to the motion system concept. The research approach used is quantitative with the type of pre-experimental research. The research design used is the one-group pretest-postest design. The population was all of 11th grade students, amounting to 292 people. The sampling technique used was a total sampling. The sample in this study consisted of 292 students. The instruments in this research were pretest and posttest multiple choice questions with reasoned. Data analysis consisted of normality test, paired sample t-test at a significant level of 0.05 and n-gain. The results of the paired sample t-test obtained tcount 48 and value (ρ.001), so it was concluded that there were differences in critical thinking skills and learning outcomes of students before and after learning with the application of the STEM-based discovery learning model to the motion system concept. The results of the n-gain test using the Meltzer formula showed that the gain in critical thinking skills was 0.85, so there was an increase in critical thinking skills with a high category.

The study aims at developing a scientific-based pictorial storybook with PjBL method for improving the critical thinking skills of the elementary school students. The research and development initiative refer to the design of Borg & Gall with 10 stages of test. Then, during the conduct of the study the data were gathered by means of product assessment sheet, teacher response questionnaire, student response questionnaire and critical thinking skills test. For the data analysis, the data were analysed by means of paired t-test with significance rate 5%. The results of the study show that the scientific-based pictorial storybook with PjBL method has been feasible for improving the critical thinking skills of the elementary school students. Based on the paired t-test results with the significance rate 5% (sig. (2-tailed) = 0.000 < α = 0.05), after the implementation the critical thinking skills of the students increase significantly.

This study aims to analyze the effectiveness of science e-modules for class VII junior high schools based on socioscientific issues to improve students' critical thinking skills. The type of research used is Pre-Experimental with one group pretest-posttest design. This research was conducted at SMP Negeri 2 Seririt in class VII A with a total of 30 students. Data were collected with 12 items of critical thinking skills test on global warming material through pretest and posttest. Data were analyzed using Paired Sample T-Test and gain score test. The Paired Sample T-Test was used to calculate the significance of increasing students' critical thinking skills, but the gain scores were used to calculate the increase in students' critical thinking skills. The results of this research showed that there was a significant difference in students’ critical thinking skills before and after used science e-module in learning (sig. < 0.05). The normalized N-gain test also showed an increase in students' critical thinking skills with a value of 0.55 in the medium category. Based on the results of the Paired Sample T-test and the normalized gain score, it can be concluded that the e-module based on socioscientific issues is effectively used to improve students' critical thinking skills.
