Abstract

Penelitian ini bertujuan untuk meningkatkan motivasi dan minat belajar matematika siswa melalui pendekatan kontekstual dalam pembelajaran matematika yang bermakna. Tujuan lain penelitian ini adalah untuk mengetahui keterlaksanaan pembelajaran dengan pendekatan kontekstual oleh guru matematika kelas VIII di SMP Negeri 7 Banjarmasin dan SMP Negeri 24 Banjarmasin. Penelitian dilaksanakan di kelas VIII B SMP Negeri 7 Banjarmasin dan kelas VIII F SMP Negeri 24 Banjarmasin. Subyek penelitian ini adalah siswa kelas VIII B SMP Negeri 7 Banjarmasin sebanyak 27 orang dan siswa kelas VIII F SMP Negeri 24 Banjarmasin tahun pelajaran 2016/2017 sebanyak 30 orang. Hasil penelitian di kelas VIII B SMP Negeri 7 Banjarmasin menunjukkan bahwa (1) keterlaksanaan pembelajaran pada siklus 1 dan 2 di SMP Negeri 7 Banjarmasin adalah 100%, (2) terjadi peningkatan motivasi dan minat belajar matematika siswa dari pra tindakan ke siklus 1 ke siklus 2. Sedangkan untuk hasil penelitian di kelas VIII F SMP Negeri 24 Banjarmasin menunjukkan bahwa (1) terjadi peningkatan persentase keterlaksanaan pembelajaran pada siklus 1 sebesar 28,7% pada pertemuan 1 dan 100% pada pertemuan 2 ke siklus 2 sebesar 100%; (2) terjadi peningkatan motivasi dan minat belajar matematika siswa dari pra tindakan ke siklus 1 ke siklus 2. Increased Motivation and Interest in Student Mathematics Learning Through Contextual Approach in Meaningful Mathematics Learning AbstractThis study aims to improve students' motivation and interest in learning mathematics through contextual approach in meaningful math learning. Another purpose of this research is to know the implementation of learning with contextual approach by teacher of math class VIII in SMP Negeri 7 Banjarmasin and SMP Negeri 24 Banjarmasin. The research was conducted in class VIII B SMP Negeri 7 Banjarmasin and class VIII F SMP Negeri 24 Banjarmasin. The subjects of this study are students of class VIII B SMP Negeri 7 Banjarmasin as many as 27 people and students of class VIII F SMP Negeri 24 Banjarmasin 2016/2017 lesson year as many as 30 people. The result of research in class VIII B SMP Negeri 7 Banjarmasin shows that (1) learning activity in cycle 1 and 2 in SMP Negeri 7 Banjarmasin is 100%; (2) there is an increase of motivation and interest in learning mathematics from pre-action to cycle 1 to cycle 2. As for the results of research in class VIII F SMP Negeri 24 Banjarmasin shows that (1) there is an increase in the percentage of learning implementation in cycle 1 of 28.7% at 1 and 100% meeting at the second meeting to cycle 2 by 100%; (2) there is an increase in motivation and interest in learning mathematics students from pre-action to cycle 1 to cycle 2.

Abstract

Penelitian ini bertujuan untuk menghasilkan bahan ajar matematika berdasarkan teori belajar Ausubel untuk siswa SMP berupa lembar kegiatan siswa (LKS), namun terlebih dahulu dikembangkan rencana pelaksanaan pembelajaran (RPP) dan tes prestasi belajar (TPB) dimana RPP dan LKS memenuhi kriteria valid, praktis, dan efektif serta TPB memenuhi kriteria valid, praktis, dan reliabel. Penelitian ini merupakan penelitian pengembangan yang diadaptasi dari model Borg & Gall yang terdiri dari tiga langkah utama yaitu studi pendahuluan, desain produk, dan pengembangan dan evaluasi. Kevalidan produk dilihat dari hasil validasi ahli dan mencapai kriteria valid untuk LKS dan sangat valid untuk RPP dan TPB. Kepraktisan produk mencapai kategori sangat praktis ditinjau dari lembar kepraktisan guru dan siswa serta observasi keterlaksanaan pembelajaran. Keefektifan produk ditinjau dari sikap, pengetahuan, dan keterampilan. Hasil uji coba lapangan menunjukkan lebih dari 70% siswa mencapai Kriteria Ketuntasan Minimum untuk pengetahuan dan keterampilan, serta mencapai kriteria baik dan sangat baik untuk ranah sikap.Kata kunci: pengembangan, bahan ajar, teori belajar ausubel Development of mathematics teaching material for junior high school students based on ausubel learning theory AbstractThis research is aimed to produce teaching material of mathematics based on Ausubel learning theory for Junior High School students in the form of student?s activity sheet, but at first the lesson plan is developed and the completeness of learning achievement test, that is the lesson plan and student activity sheet to meet the criteria for a valid, practical, and effective devices and the learning achievement test to meet the criteria for a valid, practical, and reliable devices. This research is the development of a model adapted from Borg & Gall which consists of three main steps such as the preliminary study stage, the stage of product design, and the development and evaluation stages. The validity of the products seen from the results of the validation experts stating that the products reach the valid criteria for student activity sheet and very valid for lesson plan and learning achievement test. The practicality of products seen from the practicality teachers sheet and practicality students sheet and study observation sheet. The effectiveness of the products obtained from attitudes, knowledge, and skills. The results of field trials showed more than 70 % of students achieving mastery Minimum Criteria for knowledge and skills , as well as achieving good and excellent criterion for the attitude sphere .Keywords: development, instructional materials, Ausubel learning theory
