Abstract

Penelitian ini merupakan penelitian tindakan kelas yang bertujuan untuk meningkatkan hasil belajar siswa pada materi larutan penyangga melalui penerapan model pembelajaran problem based learning (PBL) dengan pendekatan etnosains. Terdapat beberapa hal yang mendasari penelitian ini adalah rendahnya minat belajar siswa pada mata pelajaran kimia yang kemudian membuat hasil belajar siswa kurang memuaskan. Penelitian yang dilakukan merupakan penelitian tindakan kelas (PTK) yang berlangsung dalam dua siklus, pada siklus I dilaksanakan tiga kali pertemuan dan disiklus II dilaksnakan dua kali pertemuan. Masing-masing siklus pada penelitian ini terdiri dari: tahap perencanaan, pelaksanaan, observasi, dan refleksi. Teknik pengumpulan data dilakukan dengan menggunakan lembar observasi dan tes tertulis. Berdasarkan hasil penelitian yang diperoleh bahwa model pembelajaran PBL dengan pendekatan etnosains dapat meningkatkan hasil belajar siswa. Hal tersebut dapat dilihat dari presentase hasil belajar siswa yang meningkat dari 74% pada siklus I yang selanjutnya meningkat menjadi 96% pada siklus II.

Abstract

The purpose of this study was to determine the Effectiveness of the Implementation of the ICARE Learning Model on Student Chemistry Learning Outcomes in Acid-Base Material. This research was conducted in class XI MIA SMA Budi Luhur Kembang Mertha in the 2022/2023 academic year. A total of 24 students of class XI MIA were selected as the research sample. This research is a quantitative study using an experimental method with a one-group pretest-posttest design. The data collection technique uses a learning achievement test which is given a pretest before the learning process is carried out and a posttest after the learning process is carried out. From these results it can be concluded that the implementation of the ICARE learning model can effectively improve students' chemistry learning outcomes in the subject matter of class XI acids and bases at SMA Budi Luhur Kembang Mertha.

Abstract

This study aims to analyze the chritical thinking skill of university students. The sample of this study was 16 (sixteen) people taken by purposive sampling method. The study was took in Basic Chemistry class and the topic was chemical bonding. The reasearch method was qualitative descriptive reasearch. The instruments developed were test instrument and interview. The test instrument consists of four dimension such as interpretation, analysis, evaluation, and inferension. The result of this study prove that the chritical thinking skill of university students were moderate and the average percentage was 66,0625 The value of each dimensions were 62,75% for interpretation, 55,25% for analysis, 68,75% for evaluation, and the last was 77,5% for inferension.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui hasil belajar kimia siswa setelah penerapan Model Pembelajaran POGIL dengan Pendekatan Multiple Intelligence Terhadap Hasil Belajar Kimia Siswa. Penelitian ini adalah penelitian kuantitatif menggunakan metode pra eksperimen dengan desain one case study. Penelitian ini dilakukan pada kelas XI MIPA 3 SMA Negeri 1 Tompaso pada tahun ajaran 2022/2023 sebagai kelas eksperimen yang erjumlah 23 orang siswa. Pengumpulan data menggunakan tes hasil belajar yaitu posttest setelah melaksanakan proses pembelajaran. Data hasil penelitian yang diperoleh yaitu nilai rata-rata hasil belajar kimia siswa (posttest) adalah 81,89. Sebelum dilakukan uji one sample t test terlebih dahulu dilakukan uji normalitas dan didapatkan data berdistribusi normal. Hasil uji t yang diperoleh yaitu thitung = 2,138 > ttabel = 1,717, dengan taraf siginikan α = 0,05. Dengan demikian dapat disimpulkan bahwa terdapat perbedaan setelah diterapkannya model pembelajaran POGIL dengan Pendekatan Multiple Intelligence.

Abstract

Flipped classroom is a learning approach where subject matter and skills that are usually taught during class hours are delivered outside the classroom. This research aims to determine differences in student learning outcomes through the application of the flipped classroom learning model on basic chemistry material in mathematics education at Universitas Negeri Manado (Unima). This research is quantitative research using experimental methods with a one-group pretest-posttest design. The sample used in this research was class A mathematics education students with a low or no level of understanding of chemistry. The data collection technique uses a learning outcomes test where a pretest is given before the lecture process is carried out and a posttest after the lecture process is carried out. The research results showed that the average student learning outcomes in the pre-test were 37.71 and the average student learning outcomes in the post-test were 87.88. The N-Gain score test results show a score of 81% which is included in the effective and high category. Based on these results, it can be concluded that the application of the flipped classroom model improves student learning outcomes in chemical bond material in the general chemistry class at Unima’s mathematics education effectively and significantly.
