Abstract

Abstract This study aims to determine the improvement of the ability of each aspect and the overall aspects of problem solving of students mathematics, with learning using IMPROVE method accompanied by embedded test to lead to the purpose of this study is to examine: (a) students' mathematical problem solving ability seen from each aspect and overall aspects before and after learning using IMPROVE method along with embedded test, and regular learning along with embedded test; (b) student activities and attitudes toward learning by IMPROVE method along with embedded test, (c) problems that arise during learning by applying IMPROVE method along with embedded test. This study is an experimental study in the form of pretest-postes control group design, with the subject of 81 students at AN-NIZAM Private High School in Medan. The instrument used to collect the data in this study consists of mathematical tests containing mathematical problems to measure students 'mathematical problem solving skills on the subject of Equation and Quadratic Inequality, student attitude questionnaire with Likert scale model to see students' attitudes toward learning by IMPROVE method accompanied by embedded test and observation sheet of student activity in learning Keywords: Problem Solving Abilities, Improve and Embedded Test Methods

Abstract

Abstract Problems that occur in learning circle one of them is the low ability of students in understanding the concept. Understanding broad concepts of circles can be helped by using teaching materials as learning media. The teaching material should be a didactic design that is designed with due regard to the concepts, principles, object of study, and characteristics of the students. The formulation of the problem in this research is how didactic design development to improve the ability to solve the problem of student circle in accordance with obstacle learning? Specific objectives to be achieved are wide circular didactic design and increasing ability to solve circle problems. This research is a research of didactic design development with 3-D model by Thiagarajan done through Define, Design, and Develop stage Keywords: Didaktis Design, Circle Learning

Abstract

Masalah dalam penelitian ini adalah rendahnya aktivitas pemecahan masalah pada pembelajaran matematika bagi siswa di sekolah dasar. Siswa cenderung bekerja prosedural sebagaimana contoh yang diberikan, sehingga siswa tidak mampu menyelesaikan persoalan matematika yang tidak rutin. Lembar aktivitas yang digunakan guru dalam pembelajaran juga lebih menekankan pada pengerjaan soal-soal matematika yang bersifat rutin dan menerapkan rumus yang ada. Persepsi guru yang keliru terhadap lembar aktivitas siswa ini dapat mengakibatkan kurangnya penalaran dan lemahnya aktivitas siswa dalam pemecahan masalah. Salah satu alternatif yang dapat digunakan untuk mengatasi permasalahan tersebut adalah menggunakan media Lembar Aktivitas Siswa (LAS) berbasis problem posing pada pembelajaran matematika. Dengan LAS berbasis problem posing memicu siswa melakukan aktivitas matematika secara bertahap melalui proses mengamati situasi, memahami konteks masalah, mengajukan permasalahan, dan menyelesaikannya. Penelitian ini merupakan penelitian pengembangan model Borg and Gall, melalui tahapan Define, Design, dan Develop. Model LAS yang didesain divalidasi (expert apprais) oleh 2 orang validator yang kompeten pada bidang pendidikan matematika dan pendidikan dasar. Berdasarkan hasil analisis kualitatif tersebut diperoleh LAS pembelajaran matematika berbasis problem posing sesuai kompetensi matematika dan karakteristik siswa SD, yang valid dan layak digunakan
