Abstract
A new teaching method, Logo-Based Instruction (LBI), was applied for teaching basic geometric concepts: points, rays, lines, and line segments. The aim of LBI is to enable teachers and students to investigate and explore Logo integration into the geometry curriculum. Logo computer language was used for developing class activities and tutorial programs. The students used Logo to solve problems. The sample consisted of sixty-seven seventh and eighth graders (31 females and 36 males; 51 blacks and 16 whites). The regular classroom teacher taught both the experimental and the control groups using the treatment plan designed by the researcher. The results of the statistical analyses (applied to the scores of achievement tests, Likert Scales, Semantic Differential Scales, Interview Sheets; and the gain in van Hiele levels) were significant in favor of the experimental group at 0.05 level. These results are encouraging and support the use of LBI for teaching geometry.
