Abstract

A misconception is a problem that is often encountered in the world of education caused by several things, including students' initial prejudices, incompetent teachers, unclear textbooks, different contexts of the student experience, and teaching methods that only contain lectures. This study is intended to answer the problem regarding the effectiveness of cognitive conflict-based chemistry learning in reducing students' misconceptions about acid-base material. This research is quasi-experimental research with One group Pre-test and Post-test Design. The population in this study was all class XI IPA. The sample in this study was class XI IPA I. The instrument used in this study was a student's concept understanding test. The data collection method used is a multiple-choice reasoned test method. Changes in misconceptions were analyzed descriptively and statistically. A descriptive analysis was conducted to see changes in students' concepts. Statistical analysis using the T-test. Based on the research, it was found that the indicators of questions that experienced misconceptions were: Arrhenius acid-base theory (32.05%), Arrhenius acid-base classification (56.40%), Bronsted Lowry theory (43.59%), writing down the acid-base reaction equation according to Bronsted Lowry and Lewis acid-base theory (59.00%), distinguish between Arrhenius, Bronsted Lowry and Lewis acid-base theories (49.00%), the nature of acidic and basic solutions (47.00), degree of acidity/pH (79.00%), determination of strong acid (79.00%), determination of strong base (46.00%), degree of ionization in acid and base determination (46.00%) and application of the concept of pH in pollution (66.00%). Understanding of students' initial conceptions, namely students who are classified as knowing the concept of 23.18%, misconceptions of 53.95%, and not knowing the concept of 22.87%, while the understanding of the final conception of students is students who are classified as knowing concepts of 76, 20%, a misconception of 15.49% and not knowing the concept of 8.31%. Based on these data, it can be concluded that the cognitive conflict learning method is effective in reducing students' misconceptions

Abstract

The inculcation of Islamic character values for students is an important thing to be taught to students. One way of planting is to integrate learning material with the values of Islamic characters of students. This research was carried out through exploring the values of Islamic characters in hydrocarbon material taught in vocational high schools. The purpose of this study is to integrate the values of Islamic characters that are reinforced in the hydrocarbon material in schools. This research is a literature study with qualitative descriptive methods using content analysis techniques, analysis with a philosophical approach, analysis with triadic models, and analysis with confirmation models. The results obtained in this study are the study of the integration of hydrocarbon material chemistry lessons and Islamic character values that can be taught to intermediate level students. The results of the integration are as follows (1) The conversion of a less useful item into a more useful item, (2) Preserving nature as the human task as a Khalifah on earth, (3) Utilizing one of the reactions that occur in hydrocarbon compounds in daily life, (4) Utilizing petroleum as an example of a hydrocarbon product that is very beneficial to humans, (5) The benefits of carbon atoms in the carbon cycle, (6) The benefits of hydrocarbons in photosynthesis to increase our gratitude to Allah SWT, (7 ) The benefits of the special carbon atom in the concept of pairing in life, and (8) Grateful for the greatness of God who has created everything in nature

Abstract

Tantangan di dunia pendidikan pada abad 21 pendidik dituntut untuk mengembangkan model pembelajaran dalam kelas yang menarik dan menuntut peserta didik untuk memiliki keterampilan 4C salah satunya yaitu communication, dimana kemampuan ini berperan penting dalam pembelajaran sains yaitu berargumentasi ilmiah. Penelitian ini bertujuan untuk menganalisis pengaruh implementasi model pembelajaran Auditory, Intellectually, Repetition (AIR) berbantuan Talking Stick terhadap kemampuan argumentasi peserta didik pada materi larutan penyangga. Jenis penelitian ini adalah penelitian kuantitatif dengan desain penelitian pre test-post test non equivalen control group design. Teknik pengambilan sampel yang digunakan adalah cluster random sampling. Teknik pengumpulan data menggunakan instrumen soal tes, observasi, dokumentasi, dan wawancara. Berdasarkan hasil penelitian menunjukkan bahwa implementasi model pembelajaran AIR berbantuan talking stick berpengaruh terhadap kemampuan argumentasi peserta didik. Hal ini dibuktikan melalui data hasil uji N-gain kelas eksperimen (0,77) lebih tinggi daripada kelas kontrol (0,68) serta hasil uji hipotesis independent sample t-test dengan nilai sig. 2-tailed sebesar 0,012. Artinya, Ha diterima atau implementasi model pembelajaran AIR berbantuan talking stick berpengaruh terhadap kemampuan berargumentasi peserta didik.
