Geometry via Gestures: Learning 3D Geometry Using Gestures
Soumya Narayana, Prajish Prasad, T. G. Lakshmi, Sahana Murthy · 2016
Concepts of 3-dimensional (3D) Geometry are challenging to grasp for school students. The skill of manipulating 3D objects and interpreting their structure and properties are difficult. Traditionally to teach topics that have three dimensions, 3D artifacts have been used. However the opportunity of the learner to interact during the construction and manipulation of 3D objects is desirable. In this paper, we present an application - Geometry via Gestures (G-v-G), which enables learners to interact with 3D objects using their gestures. @@@@@@We report observation and analysis from an exploratory study that was performed to identify the different aspects of 3D geometry that students could learn in the process of using the application. We also examined the students' perception of learning with the application during the study. The analysis indicates that students learn about structure and property of 3D geometrical objects after using G-v-G. In addition, students participating in the study, expressed keen interest in learning additional topics of geometry using gestures.
