Abstract

Critical thinking skills are needed in chemistry learning, because some chemistry is contextual and in Indonesia is still relatively low. This study aims to stimulate students critical thinking skills on the topic of voltaic cells by developing the Selvo E-module apparatus. Research and development is carried out by adapting and modifying the development model through the preliminary study phase and development with limited trials. The sample in this study were students of class XI MIPA Academic Year 2018/2019. The instruments used were valid and reliable essay test questions and questionnaire sheets. Based on the findings obtained, it can be seen that the application of the Selvo E-module can stimulate students to think critically. It is seen from the average value of students pretest at 20.14 and the average posttest value of students is 85.07.

Abstract

The colloid system is a difficult material with the Minimum Completeness Criteria (KKM) value that is not exceeded at 92.41%. The tendency of memorized material to make students less active in the learning process. Educational games can be an effort to maximize the use of smartphones in education. This study aims to produce a product, determine the feasibility, and describe the student's response to the Android-based Kolopoly educational game learning media on the colloid system material. Development research with the ADDIE model used research subjects, namely 10 class XII students of SMAN 2 Rangkasbitung in the 2020/2021 school year. The results showed that Kolopoli was very feasible in the material sector with a percentage of 88.19% and the media sector with a percentage of 87.73%. Meanwhile, the results of student responses to the Kolopoli educational game as a learning medium got very feasible criteria with a percentage of 85.01%.

Abstract

AbstractThe ability to think critically is a 21st century ability that someone needs to have to assess information that spreads uncontrollably and solves problems with the knowledge they have. However, there are still many students who do not have the ability to think critically so they have not been able to solve problems that require critical thinking skills. The purpose of this study was to determine the differences in students' critical thinking skills before and after the application of the Argument Driven Inquiry and to find out how to increase students' critical thinking skills after the application of the Argument Driven Inquiry in buffer solution topic. research design was used one-group pretest-posttest. The sample used was 37 students of class XI IPA. The sample selection used purposive sampling. The research instrument used is the multiple choice reasoned test instrument, the lesson plan, student worksheets and observation sheets. The data analysis technique used is the paired sample t-test. The result of the calculation of the paired sample t-test is 0.000 so that there are differences in students' critical thinking skills before and after the application of the ADI learning model on the topic of buffer solutions. Through the value of N-Gain can be seen the increase of each indicator. The value obtained is that there is an increase in 6 KBK indicators. The N-gain score of each indicator has high and medium criteria.Keywords: ADI learning model; Critical Thinking; Buffer.AbstrakKemampuan berpikir kritis merupakan kemampuan abad 21 yang perlu dimiliki oleh seseorang untuk menilai informasi yang menyebar tak terkendali dan menyelesaikan masalah dengan pengetahuan yang dimiliki. Namun masih banyak peserta didik yang belum memiliki kemampuan berpikir kritis sehingga belum dapat menyelesaikan soal yang membutuhkan kemampuan berpikir kritis. Tujuan penelitian ini adalah untuk mengetahui perbedaan kemampuan berpikir kritis peserta didik sebelum dan sesudah penerapan model model pembelajaran Argumen Driven Inquiry dan mengetahui bagaimana peningkatan kemampuan berpikir kritis peserta didik setelah penerapan model pembelajaran Argument Drivent Inquiry pada topik larutan penyangga. Pada penelitian ini menggunakan desain penelitian One-Group Pretest-Posttest. Sampel yang digunakan sebanyak 37 orang peserta didik kelas XI IPA. Pemilihan sampel menggunakan teknik purposive sampling. Instrumen penelitian yang digunakan yaitu instrumen tes pilihan ganda beralasan, rencana pelaksanaan pembelajaran, lembar kerja peserta didik dan lembar observasi. Teknik analisis data yang digunakan adalah uji paired sample t-test. Hasil perhitungan uji paired sample t-test sebesar 0,000 sehingga terdapat perbedaan kemampuan berpikir kritis pada peserta didik sebelum dan sesudah penerapan model pembelajaran ADI pada topik larutan penyangga. Melalui nilai N-Gain dapat terlihat peningkatan dari masing-masing indikator. Nilai yang diperoleh bahwa terdapat peningkatan 6 indikator KBK. Skor N-gain setiap indikator memiliki kriteria tinggi dan sedang.Kata kunci: model pembelajaran ADI, berpikir kritis, larutan penyangga.

Abstract

This research aims to stimulate the understanding of Class XI MIPA 5 students at SMAN 1 Cikeusal through practical work on making a simple calorimeter. This activity was carried out at SMAN 1 Cikeusal. Through this research, it is hoped that students' perception of chemistry subjects as difficult, boring, scary and so on can slowly be reduced so that students' understanding of chemistry subjects can increase. The research method carried out was through a series of activities at SMAN 1 Cikeusal, namely carrying out practical work on making a simple calorimeter using simple tools and materials that are easily found in the surrounding environment and comparing the simple calorimeter tool with the real tool. This activity was held on Wednesday 11 October 2023, which was attended by students of SMAN I Cikeusal Kab. Serang consisting of representatives from class XI Mipa 5 with a total of 40 participants. In carrying out this activity, students showed an enthusiastic and enthusiastic attitude in participating in the learning process, especially during simple practical activities so that the chemical material being studied, namely simple calorimeters, could be understood well. Thus, the aim of the research at SMA 1 Cikeusal can be said to have been achieved because the learning outcomes of students in class XI MIPA 5 SMAN 1 Cikeusal experienced a significant increase after carrying out practicum activities. This is proven by the results of the pretest average score of 87 increasing to 93.5.
