The Effectiveness of using the (K.W.L.H) Strategy for Teaching Mathematics in Acquiring Mathematical Concepts and Developing Mathematical Thinking Skills among First-Grade Intermediate Students

Abstract

The current Study aimed to reveal the effectiveness of the strategy (K.W.L.H) for teaching mathematics in acquiring mathematical concepts and developing mathematical thinking skills among first-grade intermediate students. The experimental approach was followed, through the experimental design, with a measurement: pre- and post-by two groups, one of which was an experimental number of (34) students who studied the unit using the strategy (K.W.L.H)), and another control numbered (34) students who studied in the usual way, and they were randomly selected and appointed, and the Study materials and tools were applied, as the Study materials were: preparing the teacher's guide, and an activity booklet according to the strategy (K.W.L.H), and the tools were: testing mathematical concepts and testing mathematical thinking skills. Among the most important findings of the Study are as follows:

1. There are statistically significant differences at the level of (0.05) between the average scores of the experimental group students and the control group students in the mathematical concept acquisition test in favor of the experimental group in the dimensional application.


2. The existence of a great effectiveness of the independent variable (K.W.L.H) in acquiring mathematical concepts at the level of remembering, understanding and application and in the total degree of testing mathematical concepts among students of the experimental group compared to the control group in the post-application.


3. There are statistically significant differences at the level of (0.05) between the average scores of the experimental group students and the control group students in the mathematical thinking skills development test for the benefit of the experimental group in the dimensional application.


4. The existence of a great effectiveness of the independent variable (K.W.L.H) in the development of mathematical thinking skills, namely: (induction, generalization, conclusion, expression with symbols, modeling, reasoning and causality, criticism and evaluation) and in the total degree of testing the mathematical thinking skills of the experimental group students compared to the control group in the dimensional application.
