本研究探讨了一系列基于网络的，多媒体教程的人体成分分析方法的有效性。Turemos是围绕四个身体组成主题开发的：水密度测定法（水下称重），双能X射线吸收法，生物电阻抗分析和全身电导率。32名参加该课程的学生被随机分配通过仅基于网络的教程（“计算机”），传统的讲座形式（“讲座”）或补充基于网络的教程（“两者”）的讲座来学习材料。所有学生在随机分组前进行了有效的前测，在课程结束时进行了相同的后测。检验的信度为0.84。从测试前到测试后的平均分数变化在各组之间没有显著差异（计算机组、两者组和演讲组分别为65.4 +/- 17.31、78.82 +/- 21.50和76 +/- 21.22）。此外，Likert类型的评估发现，对所有三种格式的态度同样积极。结果表明，基于网络的教程是有效的传统的讲座形式教授这些主题。
This study examined the effectiveness of a series of Web-based, multimedia tutorials on methods of human body composition analysis. Tutorials were developed around four body composition topics: hydrodensitometry (underwater weighing), dual-energy X-ray absorptiometry, bioelectrical impedance analysis, and total body electrical conductivity. Thirty-two students enrolled in the course were randomly assigned to learn the material through either the Web-based tutorials only ("Computer"), a traditional lecture format ("Lecture"), or lectures supplemented with Web-based tutorials ("Both"). All students were administered a validated pretest before randomization and an identical posttest at the completion of the course. The reliability of the test was 0.84. The mean score changes from pretest to posttest were not significantly different among the groups (65.4 +/- 17.31, 78.82 +/- 21.50, and 76 +/- 21.22 for the Computer, Both, and Lecture groups, respectively). Additionally, a Likert-type assessment found equally positive attitudes toward all three formats. The results indicate that Web-based tutorials are as effective as the traditional lecture format for teaching these topics.
