The purpose of this study is to determine the critical thinking skills of students in class VIII B of SMP Negeri 2 Ciamis, Indonesia which emerged through a controversial issue model in social studies learning. This study used a qualitative and quantitative approach. 33 students in class VIII B were taken as the subject of this study. The four stages of classroom action research were planning, action, observation, and reflection which carried out in two cycles, and each cycle consists of two meetings. The data collection techniques used tests, observations, documentation, and field notes. The data analysis techniques used qualitative and quantitative descriptive analysis. The results of the study were: 1) social studies learning by means of a controversial issue model includes four steps, namely: (a) the teacher or student presented a case or issue related to the learning to be carried out, (b) the teacher made a group of students so that they were able to discuss problems or issues that had been presented. (c) the group representatives either as the defenders or the attackers of an opinion on a controversial issue, (d) then the teacher and students concluded and gave suggestions from the activity. 2) the implementation of the controversial Issue model in social studies learning could improve students' critical thinking skills. This can be seen from the average ability developed by each action reached 12.8 which was enough categories in cycle I, then changed to 16.8 which was good categories in cycle II. Keywords: Critical Thinking, Controversial Issues, Social Studies LearningABSTRAKTujuan dari penelitian ini adalah untuk mengetahui kemampuan berpikir kritis siswa kelas VIII B SMP Negeri 2 Ciamis yang muncul melalui model controversial issues dalam pembelajaran IPS.

Data Collection Technique

The present research aims to analyze the need for the Probing Prompting model in social studies learning to improve students' critical thinking skills during the Covid-19 pandemic. This study employs qualitative research with a descriptive analysis approach (Moleong, 2014). The data collection technique used is documentation that involves the study of some books, journals, and the regulation that is issued by the Minister of Education and Culture regarding learning policies during the Covid-19 pandemic. The results in the study show that there are various problems experienced during the social studies learning process during the Covid-19 pandemic. The problems found are (1) The social studies learning during the Covid-19 pandemic still employs conventional models, (2) Teachers assign tasks to students without providing learning materials, and (3) The social studies learning only focuses on completing materials and learning outcomes in the cognitive aspects. Therefore, the Probing Prompting model can be used as a solution and reference for teachers in the social studies learning process. The reason is that Probing Prompting model is proven to be able to improve the quality of social studies learning and improve students' critical thinking skills that are undeniably required in dealing with the Covid-19 pandemic in Indonesia.

This study aims to analyze the improvement of students’ critical thinking skills in the features of focus, supporting reasons, reasoning, organization, conventions and integration through the implementation of argument mapping-based guided inquiry learning models. Type of this research is classroom action research, a systematic inquiry with the goal of informing practice in particular situation which adopted Kemmis and McTaggart’s models which follows the cycle of planning, action, observation and reflection. It was conducted in class XI-Avenzoar of SMA Unggulan CT Foundation Deli Serdang in the academic year 2019/2020. The sampling technique was done by total sampling consisting of 24 students with a composition of 6 boys and 18 girls. The instrument used the essay tests adapted from Finken based on Illinois Critical Thinking Essay Test and argument mapping based on van Gelder on the concept of human excretory system. The data collection methods were included the interview, observation and documentation. The whole data was employed by descriptive analysis developed by Miles and Huberman which includes three concurrent activities, data reduction, data presentation and conclusion drawing. The results showed that the features of focus and reasoning from critical thinking skills tests in Cycle I obtained the highest score of all, while the features of supporting reasons and conventions obtained the lowest score and showed no improvement at all. Meanwhile in Cycle II, the features of focus and reasoning increased significantly and obtained the highest score as well. However, the feature of supporting reasons increased simultaneously but conventions still remained. It definitely showed that there was a significant improvement between groups in Cycle I (65.42) and Cycle II (80.21) from the average score of students’ critical thinking skills through their argument mapping grading. The aspects of argument mapping, such as claims, reasons, objections, rebuttals and debates improved well between these cycles. It was strongly suggested that argument mapping could enhance students’ critical thinking skills in Biology. From the results and discussion, it could be concluded that the implementation of the argument mapping-based guided inquiry learning models on the concept of human excretory system had a very positive and significant improvement on students’ critical thinking skills. The students’ critical thinking skills were in the high category.

AbstrakMata kuliah IPA Terpadu di IAIN Bengkulu merupakan mata kuliah baru bagi mahasiswa Tadris IPA. Hal ini dikarenakan pada tahun 2017/2018 baru ada tiga angkatan. Sehingga, hasil belajar mata kuliah ini tidak terlalu baik. Menurut wawancara dengan salah satu mahasiswa, salah satu penyebabnya adalah kesulitan mengintegrasikan komponen kimia, fisika, biologi secara bersamaan pada satu materi tertentu. Lebih spesifiknya, mahasiswa kesulitan untuk menjelaskan satu materi tertentu yang penjabarannya harus dijelaskan secara komprehensif baik dari segi mata kuliah kimia, fisika, biologi.  Oleh karena itu, penelitian ini bertujuan untuk melakukan perbaikan pembelajaran dan meningkatkan kemampuan berfikir kritis mahasiswa melalui pendekatan saintifik pada mata kuliah IPA Terpadu. Metode penelitian ini menggunakan penelitan tindakan kelas. Pembelajarannya terdiri dari dua siklus. Setiap siklus terdiri dari beberapa tahapan, yaitu; perencanaan, tindakan, observasi dan refleksi. Teknik pengumpulan data yang digunakan adalah observasi dan tes hasil belajar. Waktu dilakukan pada semester genap tahun akademik 2017/2018. Subjek penelitian adalah mahasiswa program studi Tadris IPA semester dua tahun akademik 2017/2018 yang sedang menempuh matakuliah IPA Terpadu. Hasil penelitian menunjukkan bahwa hasil belajar siswa yang dilakukan selama 2 siklus pembelajaran telah meningkat pada siklus yang ke-dua. Selain itu juga kemampuan berpikir kritis mahasiswa dalam pelaksanaan pembelajaran di matakuliah IPA Terpadu melalui pendekatan saintifik dapat terukur dan telah berhasil berdasarkan indikator keberhasilan. Increasing the Critical Thinking Ability of Tadris IPA Students through a Scientific Approach in Integrated Science Courses AbstractThe Integrated Science course at IAIN Bengkulu is a new subject for Tadris IPA students. This is because in 2017/2018 there were only three generations. So, the learning outcomes of this course are not very good. According to an interview with one of the students, one of the reasons is the difficulty of integrating chemical, physical, biological components simultaneously on one particular material. More specifically, students find it difficult to explain one particular material whose translation must be explained comprehensively both in terms of chemistry, physics, biology courses. Therefore, this study aims to improve learning and improve students' critical thinking skills through a scientific approach to Integrated Science courses. This research method uses classroom action research. Learning consists of two cycles. Each cycle consists of several stages, namely; planning, action, observation and reflection. Data collection techniques used are observation and learning outcomes tests. Time is carried out in the even semester of the 2017/2018 academic year. The research subjects were students of the 2017/2018 academic year Tadris IPA study program who were taking the Integrated Science course. The results showed that student learning outcomes carried out during the 2 learning cycles had increased in the second cycle. In addition, students' critical thinking skills in the implementation of learning in the Integrated Science course through a scientific approach can be measured and have been successful based on indicators of success.
