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.

Abstract

Algebraic Thinking has become a research trend to be developed in secondary and elementary schools. Algebraic Thinking, according to Kieran (2004), includes generational ability, transformational ability, and global meta ability. Permendikbud No. 58 of 2014 indirectly states mathematics is being taught to hone the algebraic thinking ability. The SAVI learning model (Somatic, Auditory, Visual, Intellectual) combines physical movement, five senses, intellectual activity. The purpose of this study was to analyze the classical mastery of algebraic thinking ability of VIIth grade students, one of junior high school in Ungaran in the SAVI learning model, to analyze the algebraic thinking ability of VIIth grade students in the SAVI learning model and PBL (Problem Based Learning), to describe the algebraic thinking ability of VIIth Grade students in the SAVI learning model. The results showed that (1) Algebraic thinking ability of VIIth Grade students in SAVI learning did not achieve classical mastery; (2) The algebraic thinking ability in SAVI learning was better than in PBL; (3) Algebraic thinking ability of VIIth in SAVI learning showed that generational ability reached 47.84%; transformational ability reached 51%, and global meta ability reached 33.8%.

Abstract

This research was carried out with the aim of analyzing the effectiveness of the MURDER learning model assisted by animated videos on students' mathematical problem solving abilities and describing mathematical problem solving abilities in terms of student learning motivation through the MURDER learning model assisted by animated videos. This research employed a mixed-method research approach with a sequential explanatory design model. The study population consisted of students from all Class VIII of SMP Negeri 6 Semarang for the academic year 2022/2023, comprising eight classes. The research sample was class VIII G, with 32 students, and class VIII F, with 32 students. The results of this research indicate that the MURDER learning model assisted by animated videos is effective for mathematical problem solving abilities. In addition, a description of students' mathematical problem solving abilities was obtained in terms of learning motivation. Students with high learning motivation meet all indicators of mathematical problem solving abilities. Students with moderate learning motivation tend to be able to meet the indicators of mathematical problem solving ability. Students with low learning motivation tend to be unable to meet indicators of mathematical problem solving ability.
