本研究的重点是双重的：一，以确定学生是否可以增加他们的物理内容的知识，通过完成一个在线的动手微机为基础的实验室（MBL）单元的运动;和两个，以确定所展示的学习收益是否相当于那些学生完成相同的MBL活动在一个更传统的课堂设置与他们的老师。来自五所不同高中的150名高中物理学生参加了这项研究。其中95人在课堂组，55人在在线组。从前测到后测，在线组的理解能力有了显著的提高。与课堂组相比，两组之间的增益分数没有显著差异。这表明，进一步的研究可能会导致开发在线，动手物理课程，可以提供给学生的学校不提供物理由于缺乏资源或物理教师。高中生应该利用学习物理的机会。那些抓住这个机会的学生应该接触到优秀的教学方法，因为学生对物理的概念理解非常低。利用建构主义原则的方法，使学生积极参与学习过程，特别有效地诱导学生的概念转变。互联网可以提供一个媒介，通过它可以维护甚至加强建构主义教学原则。
The focus of this study was twofold: one, to determine if students could increase their physics content knowledge through the completion of an online hands-on MicrocomputerBased Laboratory (MBL) unit on motion; and two to determine if the demonstrated learning gains were equivalent to those of students who completed the same MBL activities in a more traditional classroom setting with their teacher. One hundred and fifty high school physics students from five diverse high schools participated in the study. Ninety-five were in the classroom group and 55 were in the online group. The online group showed significant comprehension gains from pre-test to post-test. When compared to the classroom group, there was not a significant difference in the gain scores between the two groups. This suggests that further study could lead to the development of online, hands-on physics classes that could be offered to students whose schools do not offer physics due to the lack of resources or physics teachers. High school students should take advantage of the opportunity to learn physics. Those students who do seize this opportunity deserve to be exposed to the preeminent teaching methods available because the conceptual understanding of physics by students is extremely low. Methodologies utilizing constructivist principles whereby students actively participate in the learning process have been especially effective at inducing conceptual change in students. The Internet can provide a medium through which constructivist teaching principles can be preserved and even enhanced.
