Abstract

The purposes of this study was to know wether the student’s problem solving ability on SSCS and PBL learning models achive the mastery learning ; to compare the the student’s problem solving ability on SSCS  and PBL learning models; to describe the problem solving ability student on SSCS learning model viewed from geometry thinking levels, and to know the quality of SSCS learning models. The method used was a mixed method. The population of this study was all students of SMP N 10 Semarang. The sample was chooseb by simple random sampling technique  and class VII D as control class and VII G as experiment class.The quantitative data was analyzed by z-test to and the equivalence of two means.  The qualitative data was analyzed  through the validity test, data display, data reduction, and conclusion .  Results indicated that either SSCS and PBL learning models have achieve the mastery learning of poblem solving ability test but there was no difference between students' problem solving abilitiy in the  SSCS and PBL  learning models. Students with PreRecognition and Visual  can’t fully identify the properties of figure so it makes difficulty in solving problem. Students with Analysis level solve  problem  using the properties of certain figures.

从几何思维层次看七年级学生搜索解决问题的能力创造共享学习模式
本研究的目的是了解学生在ssc和PBL学习模式下的问题解决能力是否达到了掌握学习;比较SSCS与PBL学习模式下学生的问题解决能力;从几何思维层面描述学生在SSCS学习模式下的问题解决能力,了解SSCS学习模式的质量。使用的方法是混合方法。本研究的人群为三宝垄SMP n10的所有学生。样本采用简单随机抽样技术,以VII D类为对照类,VII G类为实验类。定量数据采用z检验和两均值等价性进行分析。对定性数据进行效度检验、数据显示、数据约简、结论分析。结果表明,SSCS和PBL学习模式均实现了问题解决能力测试的掌握性学习,但SSCS和PBL学习模式下学生的问题解决能力没有差异。具有预认知和视觉的学生不能完全识别图形的属性,给解题带来困难。具有分析能力的学生利用某些数字的性质来解决问题。
