ABSTRACTThis research is aimed to know the differences increase critical thinking skills through learning group and individual problem solving in thermochemical material. This research uses a quasi-experimental design with nonequivalent control group design and study sample consisted of 103 students, divided into the first experimental (group problem solving) (35 students), the two group experimental (individual problem solving) (34 students). The collected through pretest-posttest. The analyzed with the Kruskal Wallis test, the results showed that the learning problem solving as a group or individually can improve students’ critical thinking skills. Statistical test there are significant differences in the students critical thinking skills thermochemical material between students who received group and individual problem solving. Critical thinking skills improvement with problem solving individual learning higher compared with group learning problem solving.Keywords: problem solving learning, critical thinking skillsABSTRAKPenelitian ini bertujuan untuk mengetahui perbedaan peningkatan keterampilan berpikir kritis siswa melalui pembelajaran group dan individual problem solving pada materi termokimia. Penelitian ini menggunakan metode quasi experimen dengan desain Nonequivalent Control Group Design dan sampel penelitian ini terdiri dari 103 siswa yang terbagi ke dalam kelompok eksperimen pertama (pembelajaran group problem solving) (35 siswa), kelompok eksperimen kedua (pembelajaran individual problem solving) (34 siswa).Pengumpulan data dilakukan melalui pretest-posttest.

This research is categorized as quasy Experimental Research, by using Randomized Control Group Only Design. After implementing the Problem Based Leaning, the student was directly given the test as the result showed that the score  of the student who belong to the experimental class in  problem solving recorded as 74,00 while those who were in the control class only refers to 72,30. The test average score on the experimental class in term of math connection ability was 68,73; while in the control class recorded as 62,43. The T- Test showed that T-Table equals to 1,64 with the degree of reliability 95% . This fact reveals that the students’ ability in solving the problem after being taught through Problem Based Learning is higher than in control class with T-count equals to 3,71; while their connection math ability through Problem Based Learning Model in the Experimental Class is higher than control with T-count 2.17.Keywords: Problem Based Learning, problem solving, mathematics connection

The aim of this study was to improve the learning achievement and activities of students through the implementation of the Problem Solving learning method in Mol Concept. This study was conducted by using two cycles of classroom action research. The subject of this research was 25 students of class X-2 MAN Rukoh Banda Aceh. The result of the implementation of learning Problem Solving method showed that there is improvement of student learning achievement from Cycle I to Cycle II. It could be seen from the results of research that showing about 64% of students had passed learning in Cycle I and about 88% in Cycle II. While the observation was conducted, the improvement of learning activities of students amounts 50%. Based the result of this study, it is can be concluded that the implementation of learning Problem Solving method can improve the learning achievement and activities of the student in Mol Concept.

Tujuan penelitian ini untuk mengetahui strategi implementasi model Problem Based Learning (PBL), meningkatkan problem solving dan sikap curiosity calon guru pada mata kuliah IPA 1. Jenis penelitian ini adalah penelitian tindakan kelas dengan tahap perencanaan, implementasi dan observasi serta refleksi. Penelitian ini dilakukan sebanyak tiga siklus dengan materi yang diajarkan meliputi faktor-faktor yang mempengaruhi pertumbuhan tanaman, pemisahan campuran, dan termoregulasi. Instrumen yang digunakan berupa tes problem solving dan lembar observasi problem solving, curiosity serta keterlaksanaan model PBL. Proses pembelajaran dilakukan sesuai dengan sintaks yang terdapat dalam model PBL. Hasil penelitian menunjukkan keterlaksanaan model PBL sudah baik dengan terlaksananya semua langkah pada siklus 3. Strategi perbaikan yang dilakukan berupa memfokuskan orientasi masalah yang disajikan, membimbing calon guru dalam berbagi tugas dalam kelompok dan mengatur waktu sehingga pembelajaran lebih optimal. Hasil tes menunjukkan peningkatan rerata nilai problem solvingcalon guru dari siklus ke siklus dan di dukung dengan hasil observasi dimana tiap aspek problem solving mencapai kategorisangat baik. Dengan demikian, dapat disimpulkan bahwa penerapan model PBL dapat meningkatkan problem solving dan curiosity calon guru dalam pembelajaran IPA.Kata Kunci: problem based learning, problem solving, curiosity

This article is based on my plenary talk at the joint conference of ProMath and the GDM working group on problem-solving in 2018. The aim of this article is to consider teaching and learning problem-solving from different perspectives taking into account the connection between 1) teacher’s actions and pupils’ solutions and 2) teacher’s actions and pupils’ affective reactions. Safe and supportive emotional atmosphere is base for students’ learning and attitudes towards mathematics. Teacher has a central role both in constructing emotional atmosphere and in offering cognitive support that pupils need in order to reach higher-level solutions. Teachers need to use activating guidance, i.e., ask good questions based on pupils’ solutions. Balancing between too much and too little guidance is not easy.

Learning Management

This research intends to study the conditions and problems of learning management in Mathematics for undergraduate students. The research problem is that students have low achievement and ability problem-solving in mathematics. The research method used is development through conducting preliminary studies and quantitative survey research, producing initial designs of integrative learning models. The results of this research were used to develop the mathematics learning model. The research was conducted over one year considering two groups. The first sample was collected from the group with 376 students studying mathematics in the academic year 2020. The second sample was collected from the group with 116 professors of public universities in Thailand. Questionnaires were used as a tool of the research. The data analysis was divided into two stages. The first stage was to analyze supporting factors with factor analysis. The second stage was to design the learning management of students and professors with regression analysis. The results have shown that the opinions of students and professors on conditions and problems of learning management can be summarized as follows: (1) The students’ arguments for corrections in the aspects were group learning and teamwork, steps of solving problems, a learning model that is real situations, and the problem-based learning, respectively. (2) The professors’ opinions for corrections in the aspects were student interaction, academic achievement, problem-based learning, and learning management model that is current situations, respectively. (3)The supporting factors for developing the learning management model that professors and students were consistent in solving problems. It was found that there were three main factors as follows; group learning, problem-based learning, and active learning. The learning management model should be developed by integrating group learning, problem-based learning, and mathematical problem-solving to enhance problem-solving and mathematics learning achievement.
