The current research aims to reveal the difference between the mean scores in the posterior measurement in the constructivist thinking variable and the detection of the difference between the mean scores in the post-measurement in the achievement of Arabic language and mathematics and the detection of the difference between the mean scores of the pre and post measurements in the constructivist thinking variable and the detection of the difference between the mean scores The pre and post measurements in the achievement of the Arabic language and mathematics, and after applying the diagnostic criteria for people with learning difficulties to the initial sample, the final sample was determined by (61) of them 31 students at Nasiriyah Primary School and they were used in the current research as an experimental group on which the activities of multiple intelligences were applied, 18 students At Uwaida Primary School, 12 students at Abd Aziz Ali Primary School. The pupils of these two schools were considered as a control group, to which no activities were applied. Raven’s colored successive matrices test and diagnostic assessment scales for reading, writing and mathematics difficulties and the constructivist thinking scale were applied: preparing the researchers and obtaining academic achievement scores, and building the activities of multiple intelligences: prepared by the researchers, using the (t) test to calculate the differences, and the square ETA coefficient to calculate the size of the family, The results concluded that there were statistically significant differences between the mean scores of the experimental group and the control group in the post application of the constructivist thinking scale and degrees of academic achievement in Arabic language and mathematics in favor of the experimental group, and the presence of statistically significant differences between the mean scores of the two applications before and after the experimental group on the list of constructivist thinking and scores Academic achievement in Arabic language and mathematics
