Students who struggle with learning mathematics often have difficulties with geometry problem solving, which requires strong visual imagery skills. These difficulties have been correlated with deficiencies in visual working memory. Cognitive psychology has shown that chunking of visual items accommodates students’ working memory deficits. This study investigated the effects of visual‐chunking representation as a testing accommodation for improving students’ geometry problem‐solving performance. Participants were four third‐graders with difficulties in mathematics. An adapted reversal design was employed to examine the students’ performance changes during standard testing conditions and accommodated testing conditions. During the accommodated condition, students were presented with visual‐chunking images. Results suggested that the visual‐chunking representation accommodation improved students’ performance on geometry problem‐solving tasks, and an interview confirmed students’ preference for the visual‐chunking representation approach. 相似文献

这个故事发生在很久很久以前，离现在大约有一千五六百年了吧。那时，国王的地位最高，如果开会，国王总是独自坐在一个宽大舒适的位子上，其他的人要么离他远远地坐着，要么干脆只能站着。国于显得非常威严，别的人轻易不敢说话。有一个英国国王叫亚瑟，他有一帮能干的骑士，帮助他治理国家。 相似文献
