Abstract
The aim of the research is to know the effect. of a teaching strategy according to the Needham constructivist model in scientifically achievement in mathematics for fourth-grade students . It was adopted on Experimental mothed with the post test for achievement test to achieve the aim. The research community that represents the preparatory and secondary schools for boys has been identified within the General Directorate of Education in Baghdad / Karkh II, the research sample was selected (65) students from the fourth scientific grade from the Al-Hakim Preparatory School for Boys at random, and the sample was distributed into two groups, an experimental group and a control group :the experimental group (33) students was studied according to the Needham constructivist model. The control group of (32) students was studied according to the traditional method.The researchers made balance between. the two research. groups in some variables such as (time age, previous achievement, previous information, intelligence level), The achievement. test was built on the basis of the test map that was prepared after the content was analyzed according to the knowledge included and set (150) behavioral purposes according to the results of the analysis that was concluded, and the test is in its final form of (40) test items of two types, the objective and the number of paragraphs ( 35) The subjective and the number of its paragraphs (5). The experiment. was applied in the. first semester of the academic year (2019-2020) with (5) lessons weekly. Its plans were prepared after presenting samples of them.
