Improving Students Spatial Reasoning With Course Lab

Abstract

Geometry flat side material is crucial subject for students in senior high school. As the development of technology that increases very rapidly, it provides a chance to develop Media Interactive Learning (MPI) such as Course Lab MPI 2.4. This study was conducted to create a valid interactive multimedia teaching material, practical, and effective. Since there are correlated between spatial reasoning and student learning achievements, the influence of Course lab on the improvement of spatial reasoning is also seen. Spatial reasoning has three aspects that are mental rotation, spatial orientation, and spatial visualization. This study is a development model consisting plomp as design composed of three phases. The results obtained through this research interactive multimedia teaching material course lab based on geometry flat side were valid, practical, and effective. Students’ test scores average changed at 25 with a standard deviation of 7.07. The test results statistically demonstrated the value which means there were some differences in the average score of the initial test and final test. Course lab also led to improving students’ spatial reasoning. The multimedia developed was effective in improving both student learning achievements and spatial reasoning.

The Effect of Coding on Students’ Visual-spatial Reasoning Skills

“…According to this result, it can be said that the curriculum of the technology and design course revised with Scratch coding program was efficient in improving the experimental group students' visual-spatial reasoning skills in dimensions rotating in mind, depth perception, spatial discernment and analysis. These results show similarity with other studies in literature: in the research on middle school students by Dere (2017), significant differences in favour of students from the experimental group were determined in spatial visualization skills, imagination in mind, intersecting surfaces of the objects and skills of rotating the forms in mind; Septia et al (2018) found out that their interactive multimedia instruction was effective on mental rotation, spatial orientation and spatial visualization; in another research it was concluded that activities based on geometrical and mechanical games were efficient in improving spatial thinking skills of students of middle schools (Demirkaya & Masal, 2017). Jones and Burnett (2008) found out that there was a correlation between mental rotation ability and computer programming.…”

Students' Positioning and Emotions in Learning Geometric Definition

“…In the present research, we examine how technology affects students' positioning and emotions. In addition to the previous potentialities of technology, it can provide opportunities for students to collaborate in learning mathematics, where students' collaboration in groups has attracted the attention of researchers in mathematics education (Hoyles & Sutherland, 1989;Noss & Hoyles, 1996, Septia, et al 2018.…”

Identifying the Factor of Mathematical Reasoning That Affects the Ability to Programming Algorithm

“…Tourniaire and Pulos in 1985 argued that proportional reasoning is reasoning about the equality of two ratios (Johar, Yusniarti, & Saminan, 2018). However, according to Septia, Prahmana, Pebrianto, and Wahyu (2018), logical ability can be enhanced with continuous training. Based on these facts, mathematical reasoning training is needed for Informatics Engineering study students whose majority of students has low mathematical abilities.…”
