This study aimed at investigating the effect of the Model “Predict, observe, explain” in raising the student’s achievement and remedy for the alternative concepts acquired by the seventh-graders for the concepts contained in the unit entitled "substance its characteristics and uses." The study sample consisted of 201 male and female seventh graders who study in Ar-Razi School in Jaljulia in the scholastic year 2012-2013. The sample was divided into two groups: The experimental group (100) male and female students and the control group (101) male and female students. The control group was taught traditionally whereas the experimental group was taught by the model “predict - observe – explain”. The researcher has prepared the following research tools: Exam to determine students' prior knowledge, the teacher’s guide according to the model “predicted - observe - explain.” The results showed the existence of alternative concepts perceived by the seventh graders about some of the concepts such as the concept of mass, size, transparency, process of changing the state of matter, body, material, density, hardness, thermal conductivity, the process of equilibrium, the process of measuring size, the use of carbon dioxide in the breath photosynthesis and the distinctive character of the season. The results also showed that there are significant statistical differences between the two approaches in favor of the model “predicted -observe- explained” in reducing the number of alternative concepts being perceived by seventh graders. The results also showed that there are significant statistical differences between the achievement of the student due to the gender with favor of the female , and the results showed that there is no significant statistical differences between the number of the alternative concept due to the gender .
