The problem that arises in this study is “How to analyze children’s thinking skills in solving a problem of introducing the function of the clock and the concept of time with Schoenfels’s theory”. In detail, the problem of how student’s critical thinking skills will be discussed in accordance with the five steps of problem solving according to Schoenfeld, namely Reading, Analysis, Exploration, Implementation, and Verification. Data collection through the method of tests, interviews, and documentation with the subject is three people selected with the criteria of one high- ability student, one medium- ability student, and one low- ability student. This research is qualitative, because the type of data in this study is qualitative in the form if description of words or sentences in the form of a picture. The result of the study concluded that of the three subjects who had high, medium, and low abilities there were differences in critical thinking abilities. In short, the subject with high ability is able to master 12 indicators of critical thinking well, while the subject with moderae ability is able to master 7 of the 12 existing indicators of critical thinking, and the subject with low ability is only able to master 5 of the 12 existing indicators of critical thinking. Abstrak Masalah yang muncul dalam penelitian ini yaitu “ Bagaimana analisa kemampuan berfikir anak dalam menyelesaikan suatu masalah pengenalan fungsi jam dan konsep waktu dengan teori Schoenfeld”. Secara rinci permasalahan bagaimana kemampuan berfikir kritis siswa yang akan dibahas sesuai dengan  lima langkah pemecahan masalah menurut Schoenfeld yaitu Reading, Analysis, Exploration, Implementation, dan Verification. Pengumpulan data melalui metode tes,  wawancara, dan dokumentasi dengan subjek adalah tiga orang yang dipilih dengan kriteria satu orang siswa berkemampuan tinggi, satu orang siswa berkemampuan sedang, dan satu orang siswa berkemampuan rendah. Penelitian Ini termasuk kualitatif , karena jenis data dalam penelitian ini bersifat kualitatif berupa deskripsi kata- kata ataupun kalimat dalam bentuk gamber. Hasil penelitian disimpulkan bahwa dari tiga subjek yang mempunyai kemampuan tinggi, sedang, dan rendah ada perbedaan dalam kemampuan berfikir kritis. Secara singkat yaitu subjek yang memiliki kemampuan tinggi mampu menguasai 12 indikator- indikator berfikir kritis dengan baik, sedangkan subjek berkemampuan sedang mampu mneguasai 7 dari 12 indikator berfikir kritis yang ada, dan subjek berkemampuan rendah hanya mampu mnguasai 5 dari 12 indikator berfikir kritis yang ada.

Each student has different abilities in problem solving, especially in story problems. Haji (1994: 13) suggests that questions that can be used to determine students' abilities in the field of mathematics study can take the form of story problems. The purpose of this research is to describe the ability of students to solve mathematical problems in solving comparative story problems based on Polya's steps. This research is a descriptive study using a qualitative approach. Three (3) subjects were taken from students of class VIIA at SMP Negeri 1 Wamena consisting of one high ability student, one medium ability student, and one low ability student. Retrieval of data taken by the test and interview methods. The test used was in the form of a description test of three (3) questions. Based on the research results obtained: the ability to solve mathematical problems in High Ability Students (SKT) can do all the problem solving comparative story problems based on Polya steps, while the Medium Ability Students (SKS) there are two questions that have not fully taken Polya's steps specifically implementing the completion plan and check again. For Low Ability Students (SKR) almost all the questions given cannot be solved using Polya steps.Keywords: Problem solving, Polya steps, comparison problems.

This study aimed to investigate the relationships between teachers' knowledge, beliefs and activities about critical thinking. . The study followed the descriptive approach. This research was based on a questionnaire designed to investigate English teachers' points of view about critical thinking for primary and secondary schools in Qasabet Al Mafraq which is a city in the north of Jordan The population of the study is 280 female and male teachers distributed through 160 primary and secondary school. The study sample was randomly selected and it represents 46% of all English teachers in Qasbet Al Mafraq. They are 40 male and 88 female teachers during the second semester 2018/2019. The results of the study indicate that most of the teachers know the higher and lower –order of critical thinking skills. Also, they are inclined to use the critical thinking strategy to achieve certain outcomes in the curriculum. According to the teachers' beliefs, they think critical thinking is an important and effective strategy for problem solving and decision making. On one hand, there is a positive correlation between teacher's knowledge, teachers' belief and critical thinking activitie such as role- playing, asking questions, problem- solving, conceptual maps, debate and game playing. But on the other hand, there are no statistically significant differences at (a= 0.05) due to the variables of gender, experience, number of students, and the stage they are teaching. The researcher recommends that more research should be done on the effect of critical thinking on the four skills reading, writing, speaking and listening.

The Indonesian National Qualification Framework in higher education requires universities to develop a curriculum that makes students have superior competence with a variety of skills that are in line with the demands of the 21st century, including Critical thinking skills. The main objective of this research is to analyze the practicality of the OR-IPA learning model, which has been developed by design to improve the critical thinking skill of prospective physics teachers on the fundamentals of physics courses. The subject of practical observations was a physics lecturer who used the OR-IPA learning model. The observation sheet of the OR-IPA learning model practicality has been declared valid and reliable by the validators. The data analysis technique uses descriptive qualitative. The results showed that the OR-IPA learning model to improve the critical thinking skill of prospective physics teachers was considered practical (3.69). Lecturers and students can use the OR-IPA learning model without significant obstacles. This research implies that the OR-IPA learning model can be an alternative to improve the critical thinking skill of prospective physics teachers in the fundamentals of physics courses.

The wetland learning system is still conventional and lecturer-centered so that students are not accustomed to doing problem solving activities that have an impact on the lack of students' critical thinking skills. This study aims to develop multimedia learning of problem solving based peat swamp forest concepts to determine the validity of multimedia to train students' critical thinking skills. The stages carried out following the ADDIE instructional design flow include analysis, design, development, implementation and evaluation. Data collection techniques used a validation sheet instrument for two material experts from Lambung Mangkurat University and one multimedia expert from Politeknik Hasnur. Readability test was conducted on three active students who had taken a course to introduce the wetland environment in FMIPA ULM. The results showed that the multimedia learning concept of problem solving peat swamp forest to train critical thinking skills of chemistry students of FMIPA ULM Banjarbaru is very valid.AbstrakSistem pembelajaran lahan basah masih bersifat konvensional dan berpusat pada dosen sehingga mahasiswa tidak terbiasa melakukan kegiatan pemecahan masalah yang berdampak pada kurangnya keterampilan berpikir kritis mahasiswa. Penelitian ini bertujuan untuk mengembangkan  multimedia pembelajaran konsep hutan rawa gambut berbasis problem solving untuk mengetahui bagaimana validitas multimedia untuk melatihkan keterampilan berpikir kritis mahasiswa. Tahapan yang dilakukan mengikuti alur desain instruksional ADDIE meliputi analisis, desain, pengembangan, implementasi dan evaluasi. Teknik pengumpulan data menggunakan instrumen lembar validasi terhadap dua ahli materi dari Universitas Lambung Mangkurat dan satu ahli multimedia dari Politeknik Hasnur. Uji keterbacaan dilakukan terhadap tiga mahasiswa aktif yang pernah mengambil mata kuliah pengenalan lingkungan lahan basah di FMIPA ULM. Hasil penelitian menunjukkan bahwa multimedia pembelajaran konsep hutan rawa gambut berbasis problem solving untuk melatihkan keterampilan berpikir kritis mahasiswa kimia FMIPA ULM Banjarbaru sangat valid.
