A device called the Dex Frame has recently been marketed as an aid for children with specific learning difficulties. Using a test of reading speed and a test of reading accuracy we have attempted to evaluate the device. Two groups of children with learning difficulties were used, one having sole use of the device and being allowed to carry it with them and a second group who only used the device when attending for remedial tuition and assessment. The results show that no significant improvement occurred in reading performance of the groups with learning difficulties using the Dex Frame as compared with a control group. The teachers of the groups did, however, feel that on an individual basis some children (< 10%) expressed that they felt more comfortable using the device.
一种名为“德克斯框架”的设备最近作为一种辅助工具推向市场，用于帮助有特定学习困难的儿童。我们通过一项阅读速度测试和一项阅读准确性测试来尝试评估该设备。我们选取了两组有学习困难的儿童，一组单独使用该设备并允许随身携带，另一组仅在接受辅导和评估时使用该设备。结果表明，与对照组相比，使用“德克斯框架”的有学习困难的儿童组在阅读表现上没有显著改善。然而，这些组的教师确实感觉，个别儿童（不到10%）表示使用该设备时感觉更自在。
