2015 AD -1436 H - STUDY PROBLEM The review of literature and the findings of the pilot study revealed that there is a weakness in the fourth-grade primary stage pupil's level in the acquisition of scientific concepts and their scientific attitude in science. Thus, the present study tries to investigate the effectiveness of using the constructive-based analytical model in teaching science for the acquisition of scientific concepts and the development of scientific attitudes among fourth-grade primary stage pupils. This problem will be answered in the light of the following main question: • What is the effectiveness of using the constructive-based analytical model in teaching science for the acquisition of scientific concepts and the development of scientific attitudes among fourth-grade primary stage pupils? It is sub-divided into the following two ones: 1) What is the effectiveness of using the constructive-based analytical model in teaching science for the acquisition of scientific concepts among fourth-grade primary stage pupils? 2) What is the effectiveness of using the constructive-based analytical model in teaching science for the development of scientific attitudes among fourth-grade primary stage pupils? 3) What is the relationship between the acquisition of scientific concepts and the development of scientific attitudes among fourth-grade primary stage pupils when using the constructive-based analytical model in teaching science?
