摘要

學習障礙的理論源自於醫學，但教育研究中，大多卻只能從學生表現出來的末端結果加以探討、推論學生心理歷程，鮮少從其初端的大腦運作做研究。本研究旨在比較國小高年級數學學習障礙學生及一般學生在除法解題時之腦波差異。研究對象為6位數學學習障礙學生，及7位一般學生。研究者依照受試學生學習過的除法課程，從數學課本例題中挑選編撰本實驗使用的除法測驗題本，受試者在寫題本的同時記錄其腦波。本研究題本有低於程度計算題、當下程度計算題、低於程度應用題、當下程度應用題四種不同題型及難度，依此討論數學學障組受試學生及一般組受試學生，在θ、α、β三種腦波的差異。結果顯示，在所有題型題目中，數學學障組的θ波均顯著高於一般組學生，可見相同題目下，學習障礙學生大腦負擔的工作記憶較大，但作答的正確率卻是顯著低下。在當下程度應用題部分，一般組學生的α波顯著高於數學學障組學生，顯現一般組學生能快速調整並適應不同的數學計算，但數學學障學生卻沒辦法。

Learning disability theories are originally derived from medical science. However, most educational papers focused on student behavior and their mental activities, instead of physical brain activities. This study is to compare EEG between higher grade pupils with and without mathematical learning disabilities. There were 6 mathematical learning disable students belonging to experiment group, and there were 7 normal students belonging to control group. Division problems were selected from mathematical textbooks. EEG of the subjects was recorded when they were answering the mathematical problems. We designed four types of problems to let students calculate including easier division problems, normal division problems, easier division practical problems and normal division practical problems, The θ, α, and β waves of EGG were analyzed. The results show that the θ waves of mathematical learning disable students are significantly higher than normal ones on all types of problems. It shows that learning disable students’ brains have higher working memory loadings, but their calculating correct rates are lower. Moreover, α wave of normal students are significantly higher than learning disable students for the normal division practical problems trial. That is, normal students could quickly adapt the different typical mathematical problems but learning disable students could not.
