Abstract:
According to global assessment indicators, such as PISA and TIMSS, the performance of Greek students (Hellenic and Cypriot) in Mathematics is below the average of the countries participating in these assessments. Given these evaluations, this research presents the results from the application of RhodeScript Theory in the teaching of mathematics in Elementary School, with the aim of strengthening and improving mathematical literacy. In particular, this paper examines the difficulties faced by 5th grade students in Geometry subjects and seeks to reduce the cognitive barriers that appear in these concepts, according to the relevant literature, through teaching interventions using the mathematical tools of RhodeScript Theory. The research findings showed that students who participated in activities in which RhodeScript Theory was applied scored high on assessment projects and developed a positive attitude towards geometry. In addition, students abandoned their misconception that a triangle is the shape that has equal sides and angles.
