Investigation of 7th grade students' spatial thinking ability in a learning environment designed according to brain-based learning theory

The aim of this study is investigation of students' spatial thinking ability in a learning environment designed according to BBL theory. Besides this, within the scope of this study, it is aimed to achieve teachers and students' opinions regarding to the learning environment of BBL theory. In this study, both quantitative and qualitative research techniques were used. In the quantitative part of the study, an experimental model control group with pre-test and post-test was applied. The sample consists of 7th grade students of the secondary educational school. In the learning environment, the experimental group was designed in accordance with and the lessons carried out based on BBL theory applications; while the control group was left with current mathematics curriculum course. For the experimental and control groups, the MGMP Spatial Abilithy Test, were applied with both pre-test and post-test, and the data were analyzed by SPSS23. Also, in the experimental students were defined interviewed groups, And intervies were complated with 4 open-ended questions regarding to their spatial skills and with before and after applications proces. The obtained data were discussed in details according to the students' structure of SOLO taxonomy. In order to achieve the perceptions about the BBL theory, diaries were kept by the experimental group. In addition to the students and the teachers were interviewed at the end of pratice. Results of this study; it was determined that there was a significant difference between the control group and experimental group, in favour of experimental group students compared with others. Experimental groupstudents applications were also been raised in the level of SOLO AS( Associated Structure), but it was determined that the mental rotation ability was not developed as the same level of realization. Students and teachers also reached a positive opinion on the BBL theory. Keywords : Brain-Based Learning, Spatial Skills, Solo Taxonomy
