The study used a pretest-intervention-posttest experimental design. Results showed that students who did not have computers at home initially had lower geometry scores. However, these differences were minimised with an appropriate intervention containing computer-based Tangram puzzles. This suggests that at schools, it seems more effective to integrate mathematical content and technology in a manner that enables students to do playful mathematical discoveries.eninfo:eu-repo/semantics/closedAccessArticle36231732610.1111/j.1467-8535.2005.00460.x2-s2.0-33745196421Q1WOS:000227248300014Q2
