Teaching Topics of Biology for Second Intermediate Grade Using Adelson’s Model and its impact on developing their motivation to learn

Abstract

Abstract

     The current research aims to identify the effect of teaching biology topics for the second intermediate grade using the Adelson model  and its impact on  develop their motivation to learn. To achieve the goal of the research, the researcher adopted the experimental research method and the researcher developed tow null hypotheses To verify them, a sample of second-grade middle school students at Al-Zuhur Middle School for Boys in the city of Mosul was selected for the academic year (2023-2024) A D. It was chosen intentionally from the research community, and the total amount of its member was (88) students, (44) students for the experimental group and (44) students for the control group. The experimental group studied the topics according to the Adelson model, while the control group studied the same topics in the usual way. Then, the researcher conducted the process of equivalence between the two groups in a number of variables, (namely age in a period lasting months, general average for the first intermediate grade, academic achievement in science for the first intermediate grade, IQ score, measure of motivation to learn beforehand).it is a measure of motivation for learning prepared by the researcher. Also, the scale consists of (30) items, the answer to which is graded in three responses of agreement is to an extent  of (large/medium/slight). The scale was characterized by honesty and reliability, which was extracted using the Cronbach equation, and its reliability coefficient reached 0.85. Its discriminatory power was also extracted and two items were deleted from the scale; because, it was within the acceptable range, so the scale became (28)items in its final form. The experiment was conducted starting from the first semester of the academic year (2023/2024). The researcher took steps for equivalence between the experimental and control groups, After working on the partenership they measure of motivation to learn before starting to conduct the experiment. Then, the researcher taught biology to the experimental and control groups starting from the date of (10/17/2023) and the experiment continued until today, Tuesday, corresponding to (1/2/2024). The conduct of the experiment took (11) weeks, then  a  motivation to learn was conducted post-hoc for the experimental and control research groups on (1/4/2024). The data was collected and analyzed statistically, using statistical methods such as the T-test for two independent and correlated samples, and finding the effect size of the independent variable on the dependent and other equations to extract the coefficient of difficulty, stability, and discriminatory power. The results were as follows:

1. There is a statistically significant difference at the level of (0.05) between the average development scores of the students of the experimental group who studied according to the Adelson model and the students of the control group who studied according to the usual method in the measure of motivation to learn.
2. There is a statistically significant difference at the level of (0.05) between the average scores of motivation to learn (pre and post) for the students of the experimental group that studied biology according to the Adelson model.

In the light of the research, the researcher came to the following conclusions, The effectiveness of Adelson's model in developing motivation to learning among second-year intermediate students. The researcher  suggested  titles related to the variables of his research, such as the effect of using the Adelson model in imparting the average of other styles of thinking second-year to students at different stages.
