أثر أنموذج لاندا في تحصيل مادة الكيمياء عند طالبات الصف السابع الأساس

Abstract EN

This current research aims at identifying "The Effect of the Landa Model in Achievement to chemistry Subject in the Seventh Class basic of Female Pupils." To investigate, the aim of the major zero hypothesis has been formulated relating to the achievement (There is no significant difference in the value (0.05) between the mean scores of the experimental group studying chemistry according Landa model and the mean scores of the control group studying the same material according to the normal method) .The experimental design has been used, specifies the current research was selected (bafraw) basic mixed school among the day basic schools of the Directorate of Education canter province of Erbil for the academic year (2018-2019), where section (A) and (B) were chosen randomly the sample number mounted (58) female pupils , (29) female pupils in the section (B) of the experimental group studying according Landa model and (29) female pupils in the section (A) Of the controlled group, and the (age of female pupils is calculated by months , degree of achievement for the previous stage in science for all for the sixth grade basic , intelligence, general average for the sixth grade basic , previous information in chemistry subject , educational level of fathers , educational level of mothers) variables were equalized , and the facial validity and content validity and difficulty level , alternative effectiveness and item discrimination were checked out according to reliability coefficient by using (kuder Richardson-20) equation a recording (0.799) for the items subjected to the test.

The results showed a statistically significant difference in cognitive achievement among the pupils of the experimental group who studied the chemistry according to the Landa model on the control group studied according to the normal method, thus rejecting the null hypothesis and accepting the alternative hypothesis for the benefit of the experimental group.

Where concluded that the use of the Landa model in the teaching of chemistry leads to increased pupils achievement and recommends that the researcher use the model in teaching and suggest conducting further studies in other materials to identify the extent of their impact on achievement of pupils.
