Abstract

This research is based on understanding of mathematical concept and the lack of individual student’s responsibility. It refers to the result 8th grade from SMP N 3 Sijunjung, Year of study 2013/2014. The purpose of this research is to know understanding of student mathematical concept that apply “talking stick” with “everyone is a teacher here” is better than understanding concept of mathematical that apply conventional learning at class VIII SMP N 3 Sijunjung. This kind of research is experimental type, subject is selected randomly. This research populution is student of VIII SMP N 3 Sijunjung, year of study 2013/2014 which is consisted of five classes. to definite experiment class and control class is executed randomly. That’s how class VIII.C chosen as experiment class and VIII.B as control class. Instrumen used in this research is about understanding of mathematical concept. Type of test used is essay with test of realibility 0,718. Analysis technic used is T-test one side with MINITAB software. Based on analysis result is recognized that both class sample have normal distribution and homogeneous. Result of test is recognized as P-value < α, so hypotheses for this research is accepted. it can be concluded that understanding of student mathematical concept that apply learning model “talking stick” with “everyone is a teacher here” is better than understanding concept of mathematical that apply conventional learning at class VIII SMP N 3 Sijunjung

Abstract

Penelitian ini bertujuan untuk mengetahui praktikalitas Lembar Kerja Perserta Didik berbasis penemuan terbimbing pada materi teorema Pythagoras. Aspek-aspek praktikalitas dalam penelitian ini meliputi aspek kemudahan penggunaan LKPD, kepraktisan penyajian LKPD, keterbacaan atau bahasa, dan waktu yang digunakan. Instrument yang digunakan adalah angket praktikalitas LKPD yang telah di validasi oleh pakar matematika dan pakar bahasa. Metode penelitian yang digunakan adalah memberikan angket praktikalitas LKPD kepada guru dan peserta didik setelah field test (uji lapangan). Hasil praktikalitas LKPD menurut respon guru dari semua aspek praktikalitas adalah 85.52% dengan kategori sangat praktis dan hasil praktikalitas LKPD menurut respon peserta didik dari semua aspek praktikalitas adalah 82.7% dengan kategori praktis.
