The Effect of Landa's Model on the Acquisition of Biological Concepts Among Fifth-Grade Students – Scientific Branch in Biology

Abstract

The goal of the current research is to identify the effect of Landa’s model on the acquisition of biological concepts in biology   for the fifth scientific grade students. For the purpose of verifying the aim of the research, the researcher has developed the following null hypothesis:    There is no statistically significant difference at the level (0.05) between the average grades of the students in the experimental group who study according to the Landa model and the average grades of the students in the control group who study according to the normal method according to acquire biological concepts, in addition to that, a test for acquiring biological concepts has been prepared, which consists of (45) items. The researcher has confirmed its apparent reliability by presenting it to the arbitrators. Then he has tried the test on two exploratory samples for the purpose of extracting the psychometric properties. The research experiment has been applied in the first semester for the academic year (2023-  2024), and after the end of the experiment, a test for acquiring biological concepts has been conducted, after which the students’ answers have been  corrected and processed statistically. The results have showed that the students of the experimental group who studied according to Landa's model outperformed the students of the control group who studied according to the usual method in the acquisition test of biological concepts.
