Fourth and fifth grade students (N=171) participated in three reading tasks to assess time needed for learning, time spent in learning, and time allocated for learning. Results indicated that spending and/or allocating insufficient learning time have a direct negative effect on achievement. (BS)

The Learning for Mastery approach is clearly more effective than traditional instruction, but individualized programs are better than group-based ones. Students master more objectives with mastery learning because their level of participation is higher. (Author)

The causal effects of time spent in learning (TSL) and time needed for learning (TTL) on the reading and spelling achievement of 171 fourth and fifth grade students were investigated. TTL contributed significantly to achievement, and its direct effect was greater than TSL. Results also support a Carroll's learning model. (Author/BS)

This study examined differences in time needed for learning for three types of learning tasks from Bloom's taxonomy: knowledge, comprehension, and application. Seventh and eighth graders (N=88) were given five repeated trials to master three simulated classroom tasks. Large differences were found between tasks in mastery rates, information…
