Abstract

This study aims to: (1) find out the misconceptions experienced by students in the material of similarity and congruence by using three-tier diagnostic tests based on open-ended questions. (2) find out the large percentage of students' misconceptions on the similarity and congruence material using a three-tier diagnostic test based on open-ended questions. The research method used was descriptive qualitative. The data collection instruments used were clinical interviews and three-tier diagnostic tests based on open-ended questions. This study was conducted in the SMP Negeri 2 Palimanan. The research subjects were selected using purposive sampling techniques so that 33 students were selected from 330 students. The results of the analysis of the three-tier diagnostic test based on open-ended questions showed that (1) the misconceptions that occurred in the material of similarity and congruence of 2D shapes included pure misconceptions, false positives, and false negatives. (2) the percentage of misconceptions experienced in the material of similarity and congruence 2D shapes as a whole was 50.2% with a large percentage of pure misconceptions 32.4%, false-positive 15.6%, and false-negative 2.2%

基于开放性问题的三层诊断试验分析

本研究的目的是:(1)通过开放式问题的三层诊断测试，找出学生对相似性和一致性材料的误解。(2)采用基于开放式问题的三层诊断测试，发现学生对相似性和一致性材料的误解比例较大。本研究采用描述性定性方法。使用的数据收集工具是临床访谈和基于开放式问题的三级诊断测试。这项研究是在SMP Negeri 2 Palimanan进行的。研究对象的选择采用有目的的抽样方法，从330名学生中选出33名学生。基于开放式问题的三层诊断测试分析结果表明:(1)二维形状相似性和一致性材料中出现的误解包括纯粹的误解、假阳性和假阴性。(2)二维形状相似性和一致性材料的整体误读率为50.2%，其中纯误读率为32.4%，假阳性15.6%，假阴性2.2%
