标题： Investigating the Effectiveness of the Tutorials in Introductory Physics in Multiple Instructional Settings

摘要： 本文研究了在五种不同的教学环境中实施“能量和动量的变化”内容对教育的影响。 这些环境包括（1）完全基于计算机的学习环境以及（2）使用不同水平教师支持的合作学习小组。 前测和后测的结果表明，基于计算机的实施方式明显不如那些包含合作学习小组和与教学助理互动的课堂教学方式。 其他发现揭示了教师培训某些要素的重要性以及如何恰当使用教程作为新概念的初步介绍。 显示英文摘要

摘要： This paper examines the educational impact of the implementation of "Changes in Energy and Momentum" from the Tutorials in Introductory Physics in five different instructional settings. These settings include (1) a completely computer-based learning environment and (2) use of cooperative learning groups with varying levels of instructor support. Pre- and post-tests provide evidence that a computer-based implementation falls significantly short of classroom implementations which involve both collaborative learning groups and interactions with a teaching assistance. Other findings provide insight into the importance of certain elements of instructor training and the appropriate use of the tutorial as an initial introduction to a new concept.
