Development of STEM Animation Learning Media with Feedback to Facilitate Students’ Critical Thinking Ability on Global Warming Materials

Penelitian ini dilakukan untuk mengetahui peningkatan kemampuan berpikir kritis siswa pada mata pelajaran Termokimia melalui penerapan strategi Process Oriented Guided Inquiry Learning (POGIL) (POGIL) di kelas 11 SMAN 8 Pekanbaru. Penelitian ini menggunakan One Group Pretest-Posttest Design yang diadakan di SMAN 8 Pekanbaru pada tahun akademik 2017/2018. Objek penelitian adalah XI MIA 1 yang terdiri dari 32 siswa. Pengumpulan data siswa menggunakan teknik tes pretest dan posttest. Keberhasilan pembelajaran dalam meningkatkan kemampuan berpikir kritis siswa ditunjukkan oleh peningkatan kriteria berpikir kritis dari hasil pretest dan posttest yang menganalisis persentase skor berpikir kritis. Hasil penelitian menunjukkan bahwa ada peningkatan kemampuan berpikir kritis siswa. Siswa mengalami peningkatan dari kategori berpikir kritis sangat rendah ke kategori sangat tinggi dengan persentase 15,625%, dari kategori rendah ke kategori sangat tinggi adalah 40,625%, dari kategori rata-rata ke kategori sangat tinggi adalah 9,375%, dari kategori sangat rendah hingga kategori tinggi adalah 12,5%, dan dari kategori rendah ke kategori tinggi adalah 21,875%. Berdasarkan analisis data, dapat disimpulkan bahwa penerapan strategi Process Oriented Guided Inquiry Learning (POGIL) mampu meningkatkan kemampuan berpikir kritis siswa pada mata pelajaran Termokimia di SMAN 8 Pekanbaru. The research was held to determine the improvement of student’s critical thinking ability on Thermochemistry subject through implementation of Process Oriented Guided Inquiry Learning (POGIL) strategy at 11th Grade of SMAN 8 Pekanbaru. This research used One Group Pretest-Posttest Design which held in SMAN 8 Pekanbaru at academic year of 2017/2018. The object of research is XI MIA 1 that consist of 32 students. The data collection of students used test technique which are pretest and posttest. The success of learning in improvement of student’s critical thinking ability is showed by improvement of criteria of critical thinking from pretest and posttest results that analyzed the score percentage of critical thinking. The result of research showed that there was an improvement of student’s critical thinking ability. The students have an increase from the very low category of critical thinking to very high category with percentage of 15,625%, from low category to very high category is 40,625%, from average category to very high category is 9,375%, from very low category to high category is 12,5%, and from low category to high category is 21,875%. Based on data analyze, it can be concluded that implementation of Process Oriented Guided Inquiry Learning (POGIL) strategy is able to improve student’s critical thinking ability on Thermochemistry subject at SMAN 8 Pekanbaru.

Mathematical Critical thinking is one of mathematical abilities that must be obtained by students. Critical thinking is one of the high order thinking processes that can make concepts in student knowledge. Students with critical thinking in mathematics learning mostly do rational activities such as interpreting information based on a particular theoretical framework, linking theory with practice, making claims and justifying it, utilizing data in support of argumentation, making relations or relationships between various ideas, asking questions, evaluating knowledge, predict, describe something, analyze, synthesize, and categorize. This study aims to analyze the effect of the Concept-Based Learning Model on the critical thingking mathematical abilities.The purpose of this research is to analyze the effect of Concept-Based Learning Model toward mathematics critical thinking ability. The method used in this research is quasi experiment by Randomize Control Group Post Test Only Design with cluster random sampling technique. Indicators of mathematics critical thinking skills measured in this study include providing simple explanations, building basic skills, concluding, making more explanations, and deciding an action. The results showed that the mathematics critical thinking ability of students in the experimental class for the five indicators that being analyze was higher than the ability of students in the control class. A fairly high difference in the indicator showed in give a simple explanation and concluding. and it means that the application of Concept-Based Learning Model significantly influences the abilities of students' mathematics critical thinking.

This research is conducted by the low mathematics critical thinking ability of students in junior high schools, especially in VII grade .Students of VII grade commonly are transitioning from elementary school to junior high school could be a reason how low students of VII grade on mathematic critical thingking ability. The low ability mathematics critical thingking one of caused by mathematics anxiety. This study aims to find a relationship between math anxiety and mathematics critical thinking ability of VII grade at SMPN 5 Serang City. The method of this research is quantitative descriptive by making 110 students from VII grade as a sample. The data were collected using questionnaire and test. The result of this study indicate that 1) the ammount of correlation between math anxiety with critical thingking ability is -0,5991> rs table 0,1695, which means there is a significant and negative relationship between anxiety and critical thingking ability 2) the average of students’s mathematics critical thingking ability is different where score between students with low anxiety have a better score than student with mid anxiety and low anxiety,and students with mid anxiety have a better score than students with high anxiety, and students with mid anxiety have a better score than students with high anxiety.
