Learning design using PMRI to teach central tendency materials

Abstract

This study aims to determine the role of activities in learning the central tendency materials (mean, median, and mode), which is expected to be able for helping students understanding the concept of statistical learning in grade VIII. The method used in this study is Validation Studies type Design Research involving students of MTs Negeri 1 Palembang. There are three stages in the design research type of validation studies, namely Preparing for the experiment; The design experiment in the form of a Preliminary Teaching Experiment (Pilot Experiment) and Teaching Experiment; and Retrospective analysis. In this study only that of preliminary teaching experiment is considered. The activity begins with questions about remind the presentation of data in the diagrams, then understanding the concept of the mean, the median, and mode, the question of associating the mean and median to determine the mode. The results of the learning experiment show that through the given questions can support students to understand the concept of the central tendency and know the relevance. Errors in doing activities because students are not careful in reading information on the questions, weak in the ability to count, and don't remember or not understand about the materials given.
