Statement of The problem :The problem of the present study is exemplified in that there are some alternative conceptions of some scientific concepts among elementary school pupils, the thing which is considered an obstacle in learning science. To face this problem, the present study will attempt to answer the following questions What are the alternative conceptions of some scientific concepts among elementary school pupils ؟.What is the form of the suggested strategy in modifying the alternative conceptions of some scientific concepts among elementary school pupils?3.What is the effectiveness of the suggested strategy in modifying the alternative concepts of some scientific concepts among elementary school pupils ؟Aims and significance of the study : Preparing a diagnostic test of alternative conceptions of some scientific concepts, the thing which may be useful for researchers in the field in preparing similar tests Preparing the teacher’s guide for illustrating how the suggested strategy car be applied, the thing which science teachers can make use of in modifying conceptions among their pupils. Preparing a suggested strategy in modifying the alternative conceptions of some scientific concepts, the thing which those who are responsible for teacher preparation can make use of in implying it in teacher preparation programs.Limitations of the study This study will be limited to the following : Some kinds of cognitive maps which suits the nature of the content and elementary school pupils’ level. The alternative conceptions related to the concepts of ”the structure of the living organism” unit . This unit includes many related concepts which the pilot study emphasized that there are alternative conceptions among pupils in this unit – gist one of the first term units. A group of sixth year elementary school pupils, as it is the end of the elementary stage and at the end of this stage, it is necessary to make sure that pupils have correct scientific conception, the thing which is the base of subsequent learning. Procedures of The study : The following procedures will be followed : Identifying the alternative conceptions of some scientific concepts among elementary school pupils through : a- Review of theoretical literature related to alternative conceptions ( its definition – nature – modification strategies – diagnosis techniques).(b) Preparing a diagnostic test ( Prepared by the researcher ) in the concepts of ” the structure of the living organism ” unit and applying it on a large group of sixth year elementary school pupils. (c) Preparing a list of alternative conceptions, submitting it to a jury and modifying and setting it in its final from according to their suggestions. (2) Preparing the suggested strategy through : (a) Review of theoretical literature related to cognitive maps ( its definition – kinds – characteristics )(b) Identifying the bases and principles upon which this strategy will be built in the light of the theoretical and procedural identification of some kinds of cognitive maps, the nature of the content, learners, maturity level and the nature of alternative conceptions that will be revealed.(c) preparing media, tools and equipments required for doing activities and experiments involved in ” the structure of the living organism” unit. (3) Identifying the effectiveness of the suggested strategy in modifying the alternative conceptions of some scientific concepts among elementary school pupils through.
