The Effectiveness of Teaching Using Concept Maps on the Academic Achievement and Information Retention in Physics Among Fourth-Grade Science Students

Abstract

This research represents a serious scientific attempt to diagnose defects within the traditional educational system. The researcher identifies a core problem: the prevalence of "rote learning," which prevents students from constructing a genuine cognitive structure. To address this issue, the research population was defined as all fourth-grade scientific stream students in daytime schools under the General Directorate of Education in Al-Qadisiyah. From this population, a purposive sample was selected from "Al-Diwaniyah High School for Boys" to serve as the practical field for the study. The sample consisted of 90 students, carefully divided into two groups: an experimental group (45 students) taught using the concept mapping strategy, and a control group (45 students) taught via conventional methods.

To ensure the integrity of the experimental design, the researcher conducted a precise statistical equalization process between the two groups. This process accounted for variables such as chronological age (in months), intelligence, and prior academic achievement in physics, ensuring that any subsequent differences could be attributed solely to the independent variable (concept mapping).

Regarding the results and statistics, the students underwent an achievement test consisting of 40 objective items designed to measure levels of knowledge, comprehension, and application. Statistical treatments using the T-test for two independent samples revealed significant differences at the 0.05 level in favor of the experimental group. This group recorded a mean score in both academic achievement and information retention that clearly outperformed the control group. This statistical superiority proves that concept maps functioned as a visual tool, enabling students to organize scientific material and store it in long-term memory, thereby reducing the "interference-driven forgetting" that plagues traditional methods.

In terms of conclusions and recommendations, the study found that concept mapping reduces mental effort and time while transforming physics into an engaging subject based on discovery rather than indoctrination. Based on these findings, the researcher provided specific, practical recommendations, including the necessity of conducting intensive training courses for physics teachers in Al-Qadisiyah to master concept map construction. Furthermore, the study recommended integrating these maps into textbooks as visual summaries at the end of each chapter. The researcher also suggested conducting similar studies to measure the impact of these maps on other variables, such as creative thinking or student attitudes toward the subject, to broaden the benefit and develop the educational landscape in a comprehensive and sustainable manner
