Abstract

Abstrak: Tujuan penelitian adalah mengembangkan dan menerapkan tes diagnostik pilihan ganda tiga tingkat untuk mengukur pemahaman representasi grafik mahasiswa terkait esensi inkuiri sains dan materi optika geometri. Penelitian menggunakan metode campuran melibatkan 83 mahasiswa calon guru fisika di satu LPTK Sumatera Utara. Instrumen tes diagnostik terlebih dahulu didesain kemudian disempurnakan selama proses, direvisi, dan digunakan untuk mendeteksi dan menilai pemahaman representasi grafik mahasiswa calon guru fisika. Instrumen tes telah dikembangkan untuk dapat mendiagnosis dan memperbaiki kesalahan-kesalahan yang dilakukan calon guru fisika terkait dengan keterampilan mengonstruk grafik, menemukan kesulitan-kesulitan dalam membaca dan menginterpretasi grafik. Analisis data dilakukan secara kualitatif dan kuantitatif. Hasil studi menunjukkan pembacaan grafik dan keterampilan menginterpretasi grafik calon guru fisika masih belum memadai dan juga kemahiran dalam menganalisis grafik bergantung pada jenis grafik dan level atau tipe pertanyaan yang dikembangkan. Kata Kunci: representasi grafik, optik geometri, diagnostik tes ASSESSING OF UNDERSTANDING GRAPHICAL REPRESENTATION CONTENT GEOMETRICAL OPTIC USING DIAGNOSTIC TEST Abstract: The purpose of this study is to develop and apply three tier multiple choice diagnostic test to measure student’s understanding of graphical representation about essential features of inquiry and content geometrical optic. The study was conducted using mixed methods and carried out with 83 prephysics teachers at a University of Teachers Education in North Sumatera. The diagnostic instrument was designed and then progressively refined, revised, and implemented to detect and assess student’s understanding of graphical representation. Test instrument was developed to diagnose and correct the mistakes made by pre-service physics teachers about construction graphic skills, difficulties in the reading and interpretation graphical representation. The results of this study showed that graph reading and interpretation skills of pre service teachers were inadequate and also their graphing analysis varies depending on the type of graph and level type of question was developed. Keywords: graphical representation, geometrical optic, diagnostic test

Abstract

Indonesian students' competence in solving PISA literacy-based science questions is still relatively low compared to ASIA countries and even ASEAN countries. The research aims to develop wave material teaching materials based on PISA literacy for basic Physics courses in the Unimed Physics Study Program in the first semester of 2019/2020. This type of research is a research development using the stages of Analyze Design Develop Implement Evaluate (ADDIE). PISA-based competencies include competency in explaining science phenomena, competence in evaluating and designing science experiments and competence in interpreting the data from science experiments. In the analysis phase it was found that the available wave teaching materials did not fully support the demands of PISA competence. At the design stage, wave teaching materials are arranged by emphasizing the achievement of PISA competencies. At the development stage of the teaching material is validated by the material expert and revised according to expert input. At the implementation stage, teaching materials were tested on a small group of students and revisions were made to the material aspects of the competence of scientific inquiry and data interpretation in accordance with the difficulties found in the field. At the evaluation stage teaching materials are applied to undergraduate students in Physical Education. Results obtained: there was an increase in student responses and PISA-based competencies after using the developed wave teaching materials

Abstract

Critical thinking skills is one way to be able to understand the scientific concepts that exist in physics content as a whole in this case represented by motion content. The aim of the research is to find critical thinking skills behind success and failure in understanding the motion concepts of prospective science teachers. The concept of mechanical motion is expressed in verbal, formal, graphical, and numerical representations. The concept of motion is the subject of the problem in the first tier of the test item. The second tier of the test item measures one of the four critical thinking skills that are relevant to the subject matter. The critical thinking skills studied are reasoning effectively, using systems of thinking, making judgments and decisions, and solving problem. The results of the study show coherence between the ability to understand concepts and critical thinking skills expressed by the correlation index. The magnitude of the correlation index shows the level of coherence between understanding the concept and the underlying critical thinking skills. Empirical data shows a high correlation value between verbal representation and reasoning effectively, formal representation with using system thinking, graph representation with making judgments and decision, and numerical representation with the solving problem skills
