Digital Text Based Activity: Teaching Geometrical Entities at the Kindergarten
Plane and solid geometry are important disciplines for mathematics, computer graphics and physics. In this article, different issues concerning geometry concepts are raised and discussed. First, it was observed that there is a lack of knowledge of geometrical concepts and entities among math teachers at the level of middle school, among college students and among middle school students. Second, in order to quantify the level of knowledge about basic geometrical entities, a questionnaire made of nine items was distributed and data was collected from 15 math teachers, 90 college students and 180 elementary (6 grade) and middle school students (7 and 8 grades). Third, an action plan which aims to teach some geometrical entities is suggested. It is recommended in this article to start teaching geometry at the kindergarten using different types of real objects and tools. Among the many possible tools, digital text (multimedia) is considered to be very important due to its several natural inputs to the human sensory system.
