Abstract

Tulisan ini merupakan bagian dari penelitian yang dimaksudkan untuk mendapatkan gambaran tentang profil argumentasi mahasiswa Matematika FKIP Unram dalam melakukan pembuktian matematik. Tulisan ini hanya fokus pada data responden dalam mengembangkan argumen pembuktian pada topik Analisis Kompleks. Hasil analisis menunjukkan bahwa mahasiswa masih mengalami kesulitan dalam menyajikan argumen pembuktian yang valid. Dari 62 responden dalam membuktikan dua pernyataan matematik, diketahui bahwa hanya 24.2% argumen valid, sedangkan sisanya tidak valid, bahkan 14.5% diantaranya tidak menjawab. Kelemahan argumen yang dikembangkan diakibatkan oleh kombinasi antara tidak tepatnya Data maupun Warrant yang digunakan.

Abstract

The purpose of this study was to determine the criteria for a mathematics learning media reference book that is needed for junior high school mathematics teachers in the city of Mataram. The research begins with a survey on whether learning mathematics requires media, then identifies the frequency with which teachers use media in learning mathematics, as well as the reasons teachers never or rarely use media in learning mathematics. Based on the survey, it was found that teachers need reference books to develop mathematics learning media, so it is necessary to develop the criteria for the required reference books. Furthermore, a literature review was conducted to compare the needs (ideal conditions) for Learning Media reference books with the current state (real conditions). Conclusion The results of the study show that the materials that require media are: arithmetic operations Integers and fractions, Linear Equations, Sets and Venn Diagrams, geometry, Function values, function graph sketches, slopes of lines, Pythagoras, circles, tangents, inner circles and the outer circle of a triangle, the properties of geometric figures, similarity, congruence, cylinders, cones, and spheres. In addition, the media needed are Concept Maps, Informative Power Points, Interactive Power Points, Student Worksheets, Learning Videos, Teaching Aids, and GeoGebra. Furthermore, the criteria for a valid book were developed based on the results of the study which included 4 aspects, namely material aspects, language, presentation of material, and graphics
