Manipulative Media Technology for Addition and Subtraction of Integers in Elementary Schools

Abstract

The purpose of this study was to produce manipulative media to understand the concept of addition and subtraction of integers in grade VI students. This research method refers to Borg and Gall's theory in ten research steps including information gathering, research planning, initial product development, initial field trials, revision of trial results, main product field testing, revision of field product test results, large-scale field trials. final product revision. Data collection techniques were carried out through observation, interviews, and questionnaires. Data analysis used qualitative and quantitative analysis techniques including learning observations, and validation of manipulative media products. Sources of data in this study were teachers and students of grade VI SDN Sumbangrejo and SDN Segoromulyo. The results of this development research indicate that the media developed in the form of manipulative media made of wood can be said to be suitable for use in learning. Based on the validation from the expert, it was noted that the product was in the good category with an average score of 87%. whereas from the results of student responses the average percentage of responses to the media reached 90%. So that learning integers about addition and subtraction with manipulative media runs effectively.
