Developing Learning Instruments of Geometry Based on Van Hiele Theory to Improving Students’ Character
Year: 2018
Type: conference-paper
Abstract: This development research aims to produce learning instruments of mathematics material geometry based on Van Hiele learning theory to develop characters which are valid, practical and effective criteria. The product consists of four components, namely: Lesson Plan, Student Book, Student Worksheet, and Learning Result Test. The process of developing using 4-D model Thiagarajan consisting of 4 stages namely define, design, development and disseminate. The result of the research shows that the learning tools developed are valid, practical, and effective based on the validator and the results of the experiments evaluated. The validity was measured based on experts' validation which meet the criteria of validity, with each Content Validity greater than 75%. This indicates that the four components are in valid category. The practicality was measured by instructional management sheet shown by the fulfillment of every aspect that is in both good and excellent category. The effectiveness was indicated by the fulfillment of 3 of the 4 defined effectiveness indicators, among others: (1) The average percentage of classical completion of the learning result test is more than 85%, (2) the fulfillment of 7 of the 9 categories of student activities, (3) a positive response of 85% of each aspect being responded.
