Dynamic task selection: Effects of feedback and learner control on efficiency and motivation

Structural features of learning tasks are relevant for problem solving but not salient for novice learners. Feedback in the form of Knowledge of Correct Response (KCR) during practice is expected to help learners recognize the structural features and to profit from learner control over the selection of learning tasks. A 2 × 2 factorial experiment (N = 118) was conducted to study the effects of the KCR feedback (present and absent) and control over the selection of learning tasks (learner control and program control). The presence of the KCR feedback yielded higher efficiency on a near-transfer test as well as higher learner motivation. An interaction between feedback and control, indicating extra beneficial effects of feedback when learners control the selection of learning tasks, was not found. Theoretical and practical implications are discussed.     

The relationship between teaching practices and student achievement in first year classes

This study investigated the links between the teaching practices of primary school teachers (n = 200) who were observed while presenting a new text to their first year classes, and the student achievement levels in those classes. The teaching practices are specifically concerned with the way the teachers supported and encouraged students’ activities during verbal interactions. Two different populations were observed: classes of first year students with a reduced teacher–student ratio (about ten students per class) and classes with a normal teacher–student ratio (between 20 and 25 students per class). We found that the average level of student achievement in the reduced size classes was higher than in the standard size classes but that teaching practices differed only at precise periods of group or individual introduction to new reading texts. In these periods, we found links between teaching practices and student achievement.

实验教材对初中生体质状况的分析

本文对福建省罗源县第一中学初中学生1998-2001年三年时间里,使用《全国体育实验教材》后,在形态、机能、身体素质、健康状况等方面的变化,发现三年来学生的身体素质、肺活量、克托莱指数等有显著提高,营养不良率明显下降,男生的超重与肥胖率有所上升,近视率明显提高。今后应加强学校体育卫生工作,提高学生锻炼身体的兴趣,指导学生科学用餐,平衡膳食,培养吃苦耐劳的意志和品质等。
