Abstract


Abstract: Structure of Problem Solving in Critical Thinking Problems of Inorganic Compounds and Their Reactions. Solving problems in chemistry sometimes cannot be separated from one another. There are lots of subject matters that are interrelated with each other, which will affect the understanding of advanced material if the basic material is not understood. Objectives: This study aims to analyze the level of critical thinking skills and examine the structure of students’ thinking when solving critical thinking questions on inorganic compounds and their reactions. Methods: This study uses a descriptive research method with a quantitative approach. This study involved 30 students who participated in general chemistry courses. The research data was obtained from the results of the analysis of critical thinking test answers on inorganic compounds and their reactions. The list of multiple-choice questions using a critical thinking level and an interview section were formulated to identify difficulties in understanding the material. Findings: From the data obtained, a summary of the category level of critical thinking 3% are deficient, 67% are moderate, 23% are good, and 7% are excellent. Based on the interview, the difficulties faced by students related to their ability to connect their understanding between the sub-micro level (particle models) and the symbolic level (chemical notation) and predict the results of the reaction, and the difficulty connecting with previous material, and Conclusion : The majority of students' critical thinking skills are still low. The ideal learner should rank from the macroscopic level and the technical terms used to describe chemical phenomena (symbolic) before they begin to discuss the explanation of the next micro (molecular) domain.

Keywords: Problem solving, critical thinking, inorganic compounds and their reactions

 

Abstrak: Struktur Penyelesaian Masalah dalam Soal-Soal Berpikir Kritis Senyawa Anorganik dan Reaksi-reaksinya. Menyelesaikan permasalahan-permasalahan dalam materi kimia kadangkali tidak bisa dilepas antara satu dengan yang lainnya. Banyak sekali materi pokok yang saling berkaitan satu dengan lainnya yang akan mempengaruhi pemahaman materi lanjutan bila materi dasarnya tidak dipahami. Tujuan: Penelitian ini bertujuan untuk menganalisis tingkat kemampuan berpikir kritis dan memeriksa struktur berpikir peserta didik pada pemecahan masalah soal berpikir kritis pada senyawa Anorganik dan reaksi-reaksinya. Metode: Penelitian ini menggunakan metode penelitian deskriptif dengan pendekatan kuantitatif. Studi ini melibatkan 30 mahasiswa yang berpartisipasi pada mata kuliah kimia umum. Data penelitian diperoleh dari hasil analisis jawaban tes berpikir kritis pada materi senyawa anorganik dan reaksi-reaksinya. Daftar pertanyaan pilihan ganda menggunakan level berpikir kritis dan bagian wawancara dirumuskan untuk mengidentifikasi kesulitan-kesulitan dalam memahami materi., Temuan: Dari data diperoleh rangkuman tentang kategori level berpikir kritis 3% defiecient, 67% moderate, 23% good, 7% excellent. Berdasarkan wawancara kesulitan yang dihadapi mahasiswa terkait kemampuan untuk menghubungkan pemahaman menghubungkan tingkat sub mikro (model-model partikel) dan tingkat simbolik (notasi kimia), memprediksi hasil reaksi, dan kesulitan menghubungkan dengan materi sebelumnya., dan Kesimpulan: Mayoritas kemampuan berpikir kritis peserta didik masih rendah. Pembelajaran yang ideal seharusnya mengurutkan dari level makroskopik dan istilah-istilah teknis yang digunakan untuk menggambarkan fenomena kimia (simbolik) sebelum mereka mulai membahas penjelasannya selanjutnya domain mikro (molekul).

 

Kata kunci: Problem solving, berpikir kritis, senyawa anorganik dan reaksi-reaksinya.
