One of the most common technology-enhanced items used in large-scale K-12 testing programs is the drag-and-drop response interaction. The main research questions in this study are: (a) Does adding a drag-and-drop interface to an online test affect the accuracy of student performance? (b) Does adding a drag-and-drop interface to an online test affect the speed of student performance? In three different experiments involving fourth, sixth, and eighth graders, respectively; students answered reading comprehension questions presented in conventional (i.e., paper-based design) or drag-and-drop formats. The tests consisted of four-sentence ordering items in Experiment 1, four graphic organizer items in Experiment 2, and two cloze tests and two graphic organizer items in Experiment 3. The conventional and drag & drop groups were compared on test performance (i.e., accuracy) and efficiency (i.e., response time and number of mouse clicks). Across the three experiments, the conventional and drag & drop groups did not differ in mean performance, but the drag & drop group responded more efficiently than the conventional group (faster response time, d = 0.62, and fewer mouse clicks, d = 1.13).

大型K-12测试程序中使用的最常见的技术增强项之一是拖放响应交互。本研究的主要研究问题是：（a）在在线考试中添加拖放界面是否会影响学生成绩的准确性？（b）在在线考试中添加拖放界面是否会影响学生表现的速度？在分别涉及四年级，六年级和八年级学生的三个不同实验中；学生回答了以常规（即基于纸张的设计）或拖放形式提出的阅读理解问题。这些测试包括实验1中的四个句子排序项，实验2中的四个图形组织者项以及实验3中的两个完形填空测试和两个图形组织者项。比较各组的测试性能（即准确性）和效率（即响应时间和鼠标单击次数）。在这三个实验中，常规组和拖放组的平均性能没有差异，但是拖放组的响应效率高于常规组（响应时间更快，d  = 0.62，鼠标点击次数更少，d  = 1.13）。
