الملخص EN

This study aimed to investigate the effect of the use of the computerized crocodile chemistry program in modifying the alternative chemical concepts among students of the elementary high school.

in order to achieve the objective of the study, the researcher prepared and designed educational activities using the computerized program of the chemical compounds unit from the seventh grade science book.

the researcher tested the alternative chemical concepts, consisting of (30) paragraphs of multiple choice questions, verified its validity and stability, and the stability coefficient was (0.82).

the sample of the study consisted of (68) students of the seventh grade in the primary school for boys in hewara during the second semester of the academic year 2016/2017, and the sample was randomly distributed to two groups : a control group consists of (34) students, studied using normal way.

an experimental group, studied using crocodile chemistry.

the researcher used the appropriate statistical methods to the nature of the study to analyze the results such as : arithmetical mean and standard deviation, and used the ANCOVA analysis to identify the differences in the modification of the alternative chemical concepts.

the results of the study showed that there was a statistically significant difference(α = 0.05) between the average scores of the two groups of study (experimental and control) due to the method of teaching and for the experimental.
