The effect of using Needham's structural model on achievement and And Mathematical Interconnectivity skills Of The Second Grade Students

Abstract

The study aimed to find out the effect of using Needham's structural model on achievement and mathematical correlation skills of second-grade intermediate students. To achieve the goal, the following two hypotheses were developed:

1. There are no statistically significant differences at a significance level (0.05) between the mean scores of the experimental group students who will study according to the Needham structural model and the scores of the control group students who will study according to the usual method of achievement test.
2. There are no statistically significant differences at the level of significance (0.05) between the mean scores of the experimental group students who will study according to the Structural Needham Model and the scores of the control group students who will study according to the usual method for mathematical correlation skills. Tetouan Secondary School for Boys affiliated to the General Directorate for Education Al-Karkh II in Baghdad for the second semester (second cycle) for the year 2017-2018. The control group by (30) students. The two groups were rewarded in some variables. (44) teaching plans were prepared, including (22) according to the Needham Structural Model: for students of the experimental group and the same number according to the usual method for students of the control group, and for the purpose of measuring student achievement (20) paragraphs of the type of multiple choice were prepared as well as The mathematical correlation skills test consisting of (15) questions was applied, of which (4) objective paragraphs and (11) essay paragraphs. To process the data, the statistical package (SPSS) was used.

The results showed the following: -

1- There is a statistically significant difference at the level of significance (0.05) between the mean scores of the students of the experimental group who studied according to the Structural Needham Model and the scores of the students of the control group who studied according to the usual method in the achievement test, and in favor of the students of the experimental group.

2- There is a statistically significant difference at the level of significance (0.05) between the mean scores of the students of the experimental group who studied according to the Structural Needham model and the scores of the students of the control group who studied according to the usual method in mathematical correlation skills for the benefit of the students of the experimental group.

The researcher presented a number of conclusions, including: Needham's constructive model must be adopted when teaching mathematics subjects to second-grade students, as it has a positive effect in raising their achievement and increasing their possession of mathematical correlation skills. A number of recommendations were formulated, including: - The need to train mathematics teachers and open courses To introduce modern models when teaching students, including the Needham model, because it has a positive effect in raising their achievement and possession of mathematical correlation skills. A number of proposals were presented, including: - Conducting similar studies according to Needham's structural model for other stages of study and for other variables such as types of thinking and multiple intelligences.
