Abstract

This study aims to produce valid, practical, and effective mathematics learning tools. The development of the device in this study uses the ADDIE development model, that is Analysis, Design, Development, Implementation, and Evaluation. The data collection instruments used were in the form of validation sheets, respon questionnaire, and question grid. Data collection techniques were carried out by collecting validation and respon questionnaire that had been filled out by validator and pretest with posttest questions addressed to students. The data analysis technique used is validation, practicality, and effectiveness data analysis. The results of the analysis of device validation data on the data obtained from the three validators obtained an average syllabus validation score of 83,33% which is included in the fairly valid category which can be used but needs minor revisions. An average RPP and LKPD validation score is 82,77% and 83,44% which is included in the fairly valid category which can be used but needs minor revisions. The results of the practicality data analysis show that an average teacher respon questionnaire, that is 80% and students respon questionnaire is 80% which is included in practical. Then, the results of the effectiveness data analysis on the LKPD obtained an average, that is 77,57% which is included in effective. Furthermore, the learning devices were revised according to the validator’s suggestion, so that a mathematics learning devices with the open ended problem approach assisted by software geogebra was produced on valid, practical, and effective system linear equation of two variables material, which the device was feasible and could be used in the mathematics learning.
