The Research Of Junior High School Mathematics Learning Disabilities Students’Visual-spatial Working Memory

In the research area of Education Psychology, mathematics learning disability has an important status. As the research of learning disability gradually going deeply, mathematics learning disability was becoming the hot spot of study. According to the definition of mathematics learning disability was disunited, the researchers tend to separate it to relative learning disability and absolute learning disability, in this research, we chosen the relative learning disability, so the identification of mathematics was:the students who have normal IQ but mathematics achievement is below20%of the whole grade, and except for conceptual disability, learning motor and emotional disability.The research use the nine-block task and corsi block task as the study method, chosen113students who are recruited from grade1(63) and grade2(60) in junior school as subjects, there were61persons were mathematics learning disability (MLD) and62persons were mathematics learning excellent (MLE), then, investigated the subjects’visuo-spatial working memory(VSWM). At last, the researcher use the N-back task to training two subjects’ VSWM for20days.The study content:in order to investigate static VSWM, study one use nine-block task, to compared the performance of MLD and MLE; in order to investigate dynamic VSWM, study two use corsi block taping task, to compare the performance of MLD and MLE; in order to investigate the effect of training, study three use N-back task to train VSWM of two subjects, then compared their performance on VSWM and IQ.Conclusion:1, the performance of MLD were significantly worse than MLE on nine-block task, and the performance of nine-block would be good as growing up;2, the performance of MLD were significantly worse than MLE on corsi-block tapping task, but the performance didn’t change with age;3, after short training on VSWM, the two students’s performance on nine-block task were getting well, but there were no significant change on corsi-block task and IQ.
