Analysis Technique

This study aims to determine the effectiveness of the learning model Discovery Learning and Problem Based Learning in terms of the critical thinking skills of grade V elementary school students. This type of research is a meta analyst. The data analysis technique used is the Effect size analysis technique. The effect size formula is the effect formula with the eta squared (ή2) formula. The instrument used in this study was a coding sheet. The variables used to obtain coding information on the effect size of the meta-analysis study. The results showed that the Discovery Learning learning model was more effective than the Problem Based Learning learning model for improving students' critical thinking skills. Ancova test results show f count> f table of 0.009 and F count obtained is 6.12, namely 6.12> 0.65 and a significance of 0.001 <0.05 which indicates that there is an effectiveness of Discovery Learning and Problem Based Learning learning models in improving critical thinking skills of class students V SD.

Science Motivation

This study aims to determine the level of critical thinking skills and science motivation of students in learning science. The population in this study all students of class VIII SMP N 3 Pemalang were 10 classes with 317 students. The research sample was randomly selected with a sample of one class of 31 students. The study was conducted on January 4, 2020, data collection techniques in the form of tests and questionnaires. The test is used to determine students' critical thinking skills in learning science in simple plane materials. While the questionnaire is used to determine the level of science motivation of students in learning Natural Sciences. Descriptive quantitative data analysis and percentage. The results showed the level of critical thinking skills of Pemalang N 3 Middle School students was 35.48% from the high and medium category. While the level of science motivation of Pemalang N 3 Middle School students was 35.50% from the high and medium category. This shows that the ability to think critically and the level of science motivation of students is still quite low. So we need a learning model that can improve students' motivation and critical thinking skills.

This study intends to describe the effect of the Discovery Learning model on students' critical thinking skills in the 8th grade of junior high school. This type of research is quantitative with the method used is Quasi-Experiment. The subject of this research is 8-th grade Middle-School 2 Candi Sidoarjo consisting of an experimental grade and a control grade. Based on the results of data analysis and discussion shows that the activities of teachers in social studies learning meet the criteria both in the experimental group and better than the control class, student activity in improving students' critical thinking skills in the experimental group is better than the control class, student responses meet the positive categories, and there is a significant and influence/difference at a significant level of 5% (0.05) with a significant value or p-value of 0,000, so it can be concluded that the Discovery Learning learning model has a significant on students' critical thinking skills on material in the country's geographical conditions ASEAN countries through the atlas compared to conventional models. Characterized by the results of students 'critical thinking tests, 80.75% of students obtained an N-gain of 0.7 and the teacher's activities were carried out well and students' activities were actively and more enthusiastic in learning social studies.

The purpose of this study is to improve the critical thinking skills of Class VII Middle Scool students in social arithmetic material by applying problem posing learning. This type of research is Classroom Action Research (CAR) with Kemmis and Mc Taggart models with stages of planning, implementation, observation, and reflection. The instruments used in this study were validation sheets, observation sheets, and final cycle test sheets. The results showed that the application of problem posing learning with the following steps: the stage of apperception and motivation, the stage of conceptualization, the development and discussion stages, and the stage of correcting answers can improve the critical thinking skills of Class VII Middle School students in social arithmetic material. The average percentage of the test results of students' critical thinking skills in the first cycle was 55.2 percent and increased by 20.6 percent in the second cycle to 75.8 percent, so that this study could be said to be successful. Penelitian ini bertujuan untuk mendiskripsikan langkah-langkah pembelajaran problem posing yang dapat meningkatkan kemampuan berpikir kritis siswa SMP Kelas VII pada materi aritmetika sosial. Jenis penelitian ini adalah Penelitian Tindakan Kelas (PTK) dengan model Kemmis dan Mc Taggart dengan tahap perencanaan, pelaksanaan, pengamatan, dan refleksi. Instrumen yang digunakan dalam penelitian ini adalah lembar validasi, lembar observasi, dan lembar tes akhir siklus. Hasil penelitian menunjukan bahwa penerapan pembelajaran problem posing dengan langkah-langkah sebagai berikut : tahap apersepsi dan motivasi, tahap penyampaian konsep, tahap pengembangan dan diskusi, serta tahap mengoreksi jawaban dapat meningkatkan kemampuan berpikir kritis siswa SMP Kelas VII pada materi aritmetika sosial. Persentase rata-rata hasil tes kemampuan berpikir kritis siswa siklus I sebesar 55,2 persen dan meningkat 20,6 persen pada siklus II menjadi 75,8 persen, sehingga penelitian ini dapat dikatakan berhasil.

Guided Discovery

Discovery learning is a learning situation on wich the principle content of what is tobe learned is not give but must be independly discovered by student. The effectiveness of guided discovery learning model to improve students’ critical thinking skills uses 6 indicators, are: formulating problems, formulating hypotheses, analyzing date, providing alternatives, summing up, communicating and applying principle. The guided discovery learning model was included in the effective category in terms of: (a) Improvement (N-gain) of students’ critical thinking skills by 0.65 with moderate criteria and (b) Students respond positively to learning using guided discovery learning model and its learning tools on implementation.
