Abstract:
Spatial thinking is an ability to mentally visualize and manipulate 3D objects, identify
patterns, and to describe relationships among objects in a setting. These skills are
highly predictive for success in engineering, architecture, graphic design, computer
science, and
other fields of education.
In our education system at school’s level teachers do not focus on development of
above-mentioned skills. Which pass on to the next cadre and even reflected in the
professional life of students. Most research on spatial thinking we found is at
undergraduate level or primary level. There is need to work on adolescents of middle
school, who are at stage of learning and manipulating abstract concepts. In this study,
we developed and evaluate a spatial thinking learning application based on AR
technology. Unity3D with AR foundation libraries are used to develop the application.
The augmented and immersive characteristics of AR technology helped adolescents
(12-13 years) to visualize objects in three dimensions and to make inferences about
them. This experience provided them opportunity to actively practice spatial
constructs, enhance their spatial reasoning skills, and boost their self-efficacy to use
these skills. One group pre and posttest pre-experimental research design was
followed. Statistically significant results obtained from comparison of pre and post
surveys, also improving performance in graphs of in-app calculations provide the
evidence of learning.
