The Impact of Challenge Strategy on Student Achievement of fourth-grade Students in Biology

The aim of the research is to identify the impact of the challenge strategy in the achievement of the fourth grade students of biology. To achieve the goal, the researcher put the zero hypothesis which states: There is no significant difference at the level of significance (0.05) between the average score of students of the experimental group who will study according to the challenge strategy and average The grades of the students of the control group who will study according to the normal method of testing the collection of biology. The study sample consisted of (70) students of the fourth grade in the university's junior high school. They were randomized to two groups of 35 students in each group. The two groups were rewarded with the following variables: age, IQ test, half-year biology. In the light of the relative importance of content and behavioral purposes, an achievement test consisting of (40) multiple choice types was constructed. The researcher investigated the characteristics of the cytometric test for testing. The experiment lasted 8 weeks. At the end of the experiment, The results were then analyzed and showed that the students of the experimental group who studied according to the challenge strategy.
