The purpose of this study was to examine the effectiveness of video-based mathematics instruction for seven middle school students with specific learning disability (SLD), using an augmented reality-based training package. The dependent variable was the percentage of steps students performed correctly to solve each type of mathematics problem. The independent variable was the augmented reality video-based intervention, which used video to model the individual steps for solving four types of multistep mathematics problems: (a) addition and subtraction of integers, (b) multiplication and division of integers, (c) using ratio reasoning to convert measurement units, and (d) using multiplication and division to calculate rate of change. Results indicated a functional relation between the video-based mathematics intervention and the percentage of steps completed correctly for each type of problem. All seven participants showed significant gains immediately after receiving the intervention and maintained improved problem-solving skills in at least three out of the four problem categories.
本研究的目的是使用基于增强现实的训练包,检验针对七名患有特定学习障碍(SLD)的中学生的视频数学教学效果。因变量是学生正确完成解决每种数学问题步骤的百分比。自变量是基于增强现实视频的干预措施,该措施使用视频对解决四种多步骤数学问题的各个步骤进行示范:(a)整数加减法,(b)整数乘除法,(c)使用比率推理转换计量单位,以及(d)使用乘除法计算变化率。结果表明,基于视频的数学干预措施与每种问题类型正确完成步骤的百分比之间存在函数关系。所有七名参与者在接受干预后立即都有显著进步,并且在四个问题类别中的至少三个类别中保持了提高的解题技能。
