The purpose of this research is to know the effect size of cooperatif learning model to critical thinking skills students at physics learning Class 8th grade Junior High School 24 Bandar Lampung. The type of this research was a quasi experimental with pretest - posttest control group design. The research involved two groups of students who accounted for 34 students for experiment class and 36 students for control class. The collection of data obtained using a test instrument shaped essay at critical thinking skills level. The results show that cooperative learning model type NHT have effect to critical thinking skills on effect size index 0,7. The effect size index 0,7 show that NHT to outcome critical thinking skills of students i.e 62 % better than control class.  Experiment class is better than control class at random sampling are 0,58 it means each one of 100 random sampling  give effect for 58 sampling to improve critical thinking skills of students at learning physics.Penelitian ini bertujuan untuk mengetahui effect size dari model pembelajaran kooperatif tipe numbered heads together (NHT) terhadap kemampuan berpikir kritis siswa pada pembelajaran fisika  kelas VIII SMP Negeri 24 Bandar Lampung. Jenis penelitian ini adalah quasi eksperimen dengan pretest - posttest control group design. Penelitian ini melibatkan 2 kelompok belajar siswa yang berjumlah 34 siswa untuk kelas Eksperimen dan 36 siswa untuk kelas kontrol. Pengumpulan data diperoleh dengan menggunakan instrumen tes berbentuk essay pada level kognitif kemampuan berpikir kritis. Diperoleh hasil penelitian bahwa model pembelajaran kooperatif tipe NHT mempunyai pengaruh terhadap kemampuan berpikir kritis pada pembelajaran fisika dengan indeks effect size sebesar 0,3.

Nowadays the development of thinking skills has become the main focus in educational research. Standard of graduate competency mandate that graduates of schools to universities in Indonesia must have thinking skills.  Related to this, the goal of this quasi-experimental study was to describe the effectivity of Project-Based Learning (PjBL) student worksheets to improve students' critical thinking skills (CTS) in the topic of mixtures separation. This study was carried out in the SMPN 1 Pugung by using the Non-Equivalent (Pretest-Posttest) Control Group Design. The effectivity of PjBL student worksheets measured based on the n-gain and the effect size values. Statistically, the n-gain value of the experimental class was higher than the control class. The effect size value was in medium categorized.  These results indicated that the PjBL student worksheets were effective to improve students' CTS in the topic of mixtures separation. Keywords: student worksheets, project-based learning, critical thinking skills, mixtures separation

This research aims to determine the effect of Problem Based Learning using puzzle media on students' critical thinking. The study population was all grade VII students at SMP Muhammadiyah 3 Bandar Lampung totaling 192 people. The research sample was students from 2 classes, namely class VII D and VII F who were selected from the population by using purposive sampling technique. The research instrument used a pretest-posttest sheet. The design used is the nonequivalent control group design. The data analysis used t-test with a significance of 5%. The results showed a sig significance value. (2-tailed) 0.13 <0.05, which means that the n-Gain mean of critical thinking learning outcomes of students between the experimental class and the control class is significantly different. Thus, it is known that the problem-based learning model using puzzle media can affect the critical thinking skills of students.

This research is a quasi-experimental research with a nonequivalent control group design. This research also involved two research subjects, namely the experimental class and the control class. The population of this research was the tenth-grade students of SMA Gajah Mada Bandar Lampung. The samples were determined using the cluster random sampling technique. In collecting the data, the researchers employed a critical thinking test and a Likert scale questionnaire. The research data were analyzed using the ANOVA test. The results showed that the experimental class’s average score on the pretest experienced an improvement, from  64.96 to 84.24. The PjBL model with the STEM approach improved students' critical thinking skills and self-efficacy. The improvement was marked by the average pre-test and post-test scores improvement for each indicator, from 60.86 to 81.22. The improvement of pretest and posttest scores determined by the N-gain test was 0.55 or 31%. Furthermore, the average self-efficacy score obtained by the experimental class was 135.04, or 93% within the excellent category. Therefore, it can be concluded that the PjBL model with the STEM approach influenced the tenth-grade students' critical thinking skills and self-efficacy on ecosystem learning materials.

<p class="Abstrak"><strong>Abstract:</strong> This study aims to determine the differences in the ability to think critic of elementary school students by applying the model of Problem Based Learning (PBL) and Conventional. This type of research that is a quasi-experimental design Nonequivalent Control Group Design. Number of respondents 72 students, 36 students in grade control (conventional) and the experimental class of 36 students (PBL). Instruments used the descriptions written tests. Based on research results using the Independent Sample T-Test results obtained 0.000 &lt;0.05. This means that there are difference significant between critical thinking skills in the classroom with the conventional model and PBL. These results are supported by the acquisition of the average yield of critical thinking skills acquisition experimental class with a mean = 14.2, while the control class to get mean = 12.4. So it could be concluded that there were significant differences of critical thinking skills class with PBL and conventional models.</p><strong>Abstrak:</strong> Penelitian ini bertujuan guna mengetahui perbedaan kemampuan berpikir ktitis siswa SD dengan menerapakan model <em>Problem Baased Learning</em> (<em>PBL</em>) dan <em>Konvensional</em>.
