This research aims to improve senior high school students’ physics problem-solving skills through learning used IBMR learning model. This research was a pre-an experimental study with a one-group pre-test and post-test design. The Methods of data collection used validation and test. The materials used to teach were valid category by two experts and can be used to practice physics problem-solving skills. The average post-test score physics problem-solving ability was 73.24 with an N-gain of 0.59 was classified as moderate. The success of IBMR learning model-based devices in practicing problem-solving abilities can be seen in the increase in the average score in each indicator of problem-solving abilities. The indicator of understanding the problem had the highest post-test average score of 94.58 with an N-gain of 0.89 in the high category. The problem-solving indicator had the lowest posttest average score was 58.22 with N-gain 0.39 and mean that it was the moderate category. Based on the results study, it can be concluded that the learning used by IBMR learning model can practice the ability to solve physics problems on heat material and its displacement. Learning with the IBMR learning model was expected to train students in solving physics problems. The stages in the IBMR learning model can help students

The main target of the current study is to explain the metacognition of junior high school students with Field Independent (FI) and Field Dependent (FD) cognitive styles in mathematics problem-solving. It should be noted that the statistical population of this study was all junior high school students in the Sragen regency in the 2018/2019 academic year. To reach the research purpose, different instruments such as the cognitive style tests, the problem-solving exercises, and the interview guidance were used. Data analysis was carried out by data collection, data reduction, data presentation, and conclusion. The results indicated that the students who have field-independent cognitive style had high self-confidence that they were able to solve the problem correctly, able to do planning steps, able to make important decisions for themselves, so they can solve the problem properly. Students with FD cognitive style are completely confident that their answer is correct, but they have not yet clarified the steps they need to solve their problems and have not yet focused on their shortcomings in mathematics problem solving, so their task results in mathematics problem-solving incorrectness answer.   Keywords: Cognitive style; Mathematics problem solving; Metacognition

Penelitian ini bertujuan untuk mendeskripsikan proses berpikir kritis siswa SMA dalam pengajuan soal matematika berdasarkan tingkat kemampuan matematika yang terdiri atas kemampuan matematika tinggi, sedang dan rendah. Subjek penelitian adalah siswa kelas X dan berjumlah lima orang. Adapun hasil penelitian yang menggambarkan proses berpikir kritis siswa SMA dalam pengajuan soal berdasarkan tingkat kemampuan matematika sebagai berikut. 1) Siswa berkemampuan matematika tinggi kategori baik dalam pengajuan soal matematika memahami petunjuk dan informasi, menggunakan pengetahuan yang telah diperoleh sebelumnya sebagai sumber ide dan memiliki beberapa kriteria untuk membuat soal. 2) Siswa berkemampuan matematika sedang dengan kategori baik dalam pengajuan soal matematika memahami petunjuk dan informasi pada masalah terkait pengajuan soal, mengenali perintah dan mengidentifikasi asumsi-asumsi mendasar berupa apa yang diketahui pada informasi yang diberikan. 3) Siswa berkemampuan matematika rendah kategori kurang baik dalam pengajuan soal matematika memahami petunjuk dan informasi yang pada masalah terkait pengajuan soal. Mengacu pada hasil penelitian terlihat bahwa proses berpikir kritis siswa SMA dalam pengajuan soal matematika berdasarkan tingkat kemampuan matematika berbeda-beda.This study aims to describe Senior High School students critical thinking process in mathematics problem posing based on their mathematics ability level that is consisted of high, medium and low ability level. The subjects of this study is are five grade X students. The data were collected through semi-structured interview. This research then illustrates senior high school students critical thinking process in mathematic problem posing based on their mathematic ability level as follows: 1) The student have high mathematic ability in mathematic problem posing that might be categorized baik could understand the instruction and information, use her previous knowledge as the source of idea and having some criteria to make problems. 2) The student have medium mathematics ability in mathematics problem posing that might be categorized baik could understand the instruction and information related to problem posing, identify the instruction basic assumptions due to the knowledge she attained form given information. 3) The student have low mathematics ability in mathematics problem posing that might be categorized kurang baik could understand the instruction and information in mathematics problem posing. Referring to the research findings, it is known that senior high school students critical thinking process in mathematics posing problem is different based on their mathematic ability level.

Mathematics Problem

This study describes the profile of vocational high school students' metacognitive abilities in mathematics problem solving based on their logical thinking abilities. This research was conducted using descriptive research methods with a qualitative approach. The data was collected using a logical thinking ability test and problem-solving test and. Three students were selected who met different logical thinking stages: the abstract operation stage, the transition stage, and the concrete operational stage. The results showed the subject of the abstract operation stage fulfilled the metacognition stage by re-describing the given problem, knowing the relationship between what was known and what was asked, working on the problem by writing down what was known and asked and entering into the formula and also checking the answer. Transition stage subjects fulfill the metacognition stage by describing initial information and instructions, performing problem-solving steps, and counting to check completed work. The subject of concrete operations fulfills the metacognition stage by stating information and instructions that are non-specific and detailed. The subject has not been able to state the proper steps to ensure the information's conformity with the problem, and the subject sees what is done by calculating.
