Abstract This study aims to describe physics students’ understanding of the concept of electric fields through a multi-representation review in a qualitative way. This research is a qualitative research using test and interview techniques to obtain the data. The research subjects consisted of 6 students from Physics Education department. The test used is an essay test which includes indicators of translation, interpretation and extrapolation on the concept of an electric field. The more in-depth interviews with respondents related to the concept of the electric field were carried out in this study. Based on data analysis, it can be concluded that students’ conceptual understanding is in the moderate category. The highest scores obtained are in translation, interpretation, and extrapolation respectively, which show that the level of indicator complexity affects student achievement. This research implies that the poor conceptual understanding of students on extrapolation indicators caused by the lack of creativity in students’ thinking in exploring the whole information presented on a particular issue. Thus, a learning method that priorities high-level critical thinking skills is extremely needed.

Thinking Disposition

The present study aimed at describing the dispositions of students around a coffee plantation in solving algebraic problems, especially those pertaining to fraction and comparison. Critical thinking disposition denotes the initial milestone to developing students’ critical thinking skills. The study investigated four components of critical thinking dispositions, comprising of truth-seeking, open-mindedness, self-confidence, and inquisitiveness. The subjects under investigation were 45 students at the second grade of a junior high school situated around Garahan coffee plantation in Jember district, East Java, Indonesia. The study covered several phases, inter alia, (1) describing problems on Algebra to the students, (2) recording any activities of the research subjects when doing tasks given, (3) analyzing the students’ answer sheets based on four components of critical thinking dispositions, (4) conducting method triangulation projected to confirm the preliminary findings on the students critical thinking dispositions, and (5) determining the students’ critical thinking dispositions based on the results of direct observation, video recording, and interview. The study gained several findings related to the students’ dispositions. First, the students’ tendency in truth-seeking was characterized by their analysis on the problems given on themes regarding coffee. This prevented them from making mistakes as they checked some information, be it known or unknown, as the bases for problem solving. However, not every student was aware of what was unknown about the problem or what was required to solve the problem. Second, their tendency in open-mindedness was evinced by the fact that they were assured of their answer as they related it to their experience in planting coffee. Nevertheless, some students tended to ask their parent when they had to determine the amount of diameter comparison between two logs to be connected. Third, they tended to be confident in solving problems given as they had experienced the activities described in the problem when they assisted their parents in planting coffee, but still some students had yet to be sure of their answers as they lacked the experience in planting coffee. Lastly, they tended to possess sound inquisitiveness concerning various issues pertinent to solving algebraic problems, especially themed on coffee. They acquired the inquisitiveness by observing the actual activity in their environment. Nonetheless, their inquisitiveness could not be generalized to algebraic lessons at school.

This article explores the skills and difficulties in critical thinking of junior Indonesian high school students in mathematics learning. Fifty students of grade IX who were purposive randomly selected from state junior secondary schools in Yogyakarta City were involved as the research subjects. The data were obtained from the test of mathematical critical thinking on the material of geometry. The test consisted of four items that describe each aspect of critical thinking skills, namely interpretation, analysis, evaluation, and inference. The analysis was done by showing the steps of the students ‘answers. The result indicated that the average of the aspects of mathematical critical thinking of students were on the high criteria with students’ greatest difficulties being in the analysis standard. Meanwhile,the average student success in the interpretation standard was 82%, the standard of the analysis was 46.25%, the evaluation standard was 78.25%, and the inference standard was 77%. Furthermore, from the results of the sample students’ exploration answers, it is expected that future teaching should not only focus on fluency in calculation but also on training the students in how to explain the solution steps of the problem solving process as this is important part in critical thinking.

AbstrakMata kuliah IPA Terpadu di IAIN Bengkulu merupakan mata kuliah baru bagi mahasiswa Tadris IPA. Hal ini dikarenakan pada tahun 2017/2018 baru ada tiga angkatan. Sehingga, hasil belajar mata kuliah ini tidak terlalu baik. Menurut wawancara dengan salah satu mahasiswa, salah satu penyebabnya adalah kesulitan mengintegrasikan komponen kimia, fisika, biologi secara bersamaan pada satu materi tertentu. Lebih spesifiknya, mahasiswa kesulitan untuk menjelaskan satu materi tertentu yang penjabarannya harus dijelaskan secara komprehensif baik dari segi mata kuliah kimia, fisika, biologi.  Oleh karena itu, penelitian ini bertujuan untuk melakukan perbaikan pembelajaran dan meningkatkan kemampuan berfikir kritis mahasiswa melalui pendekatan saintifik pada mata kuliah IPA Terpadu. Metode penelitian ini menggunakan penelitan tindakan kelas. Pembelajarannya terdiri dari dua siklus. Setiap siklus terdiri dari beberapa tahapan, yaitu; perencanaan, tindakan, observasi dan refleksi. Teknik pengumpulan data yang digunakan adalah observasi dan tes hasil belajar. Waktu dilakukan pada semester genap tahun akademik 2017/2018. Subjek penelitian adalah mahasiswa program studi Tadris IPA semester dua tahun akademik 2017/2018 yang sedang menempuh matakuliah IPA Terpadu. Hasil penelitian menunjukkan bahwa hasil belajar siswa yang dilakukan selama 2 siklus pembelajaran telah meningkat pada siklus yang ke-dua. Selain itu juga kemampuan berpikir kritis mahasiswa dalam pelaksanaan pembelajaran di matakuliah IPA Terpadu melalui pendekatan saintifik dapat terukur dan telah berhasil berdasarkan indikator keberhasilan. Increasing the Critical Thinking Ability of Tadris IPA Students through a Scientific Approach in Integrated Science Courses AbstractThe Integrated Science course at IAIN Bengkulu is a new subject for Tadris IPA students. This is because in 2017/2018 there were only three generations. So, the learning outcomes of this course are not very good. According to an interview with one of the students, one of the reasons is the difficulty of integrating chemical, physical, biological components simultaneously on one particular material. More specifically, students find it difficult to explain one particular material whose translation must be explained comprehensively both in terms of chemistry, physics, biology courses. Therefore, this study aims to improve learning and improve students' critical thinking skills through a scientific approach to Integrated Science courses. This research method uses classroom action research. Learning consists of two cycles. Each cycle consists of several stages, namely; planning, action, observation and reflection. Data collection techniques used are observation and learning outcomes tests. Time is carried out in the even semester of the 2017/2018 academic year. The research subjects were students of the 2017/2018 academic year Tadris IPA study program who were taking the Integrated Science course. The results showed that student learning outcomes carried out during the 2 learning cycles had increased in the second cycle. In addition, students' critical thinking skills in the implementation of learning in the Integrated Science course through a scientific approach can be measured and have been successful based on indicators of success.
