The investigation evaluates the effectiveness of six instructional programmes with Bahraini secondary students in the age range 13‐17. Each programme was concerned with a different aspect of a spatial task in relation to diagrams of three‐dimensional structures. Pre‐tests for each of these different tasks revealed that performance increased significantly with chronological age. All programmes brought about a significant degree of learning over all the age‐groups. However, the pre‐existing differences between the age groups remained after instruction. For the programme concerned with visualising rotations, the 17‐year olds improved their scores significantly more than the 13‐ and 15‐year olds. 相似文献
