The study investigated elementary school pupils' ideas concerning the concept of electricity and the effect of school instruction on the pupil's views. Pupils of different cultural backgrounds were assessed to ascertain their knowledge in four areas: Relation of certain natural phenomena to electricity; Mental models (images) of direct current in a circuit; Images possessed regarding electricity and electric current. Pupils' ideas were investigated before and after instruction, thus providing information about the effect of instruction on the views of pupils. In construct to the previous findings, certain phenomena (lightning and thunder among them) were related by the pupils to electricity even before those were taught. Evidently, the instruction changed the mental models and images of electricity and electric current.KEY WORDS: introductory instruction, mental models, direct current, scheme-of-knowledge, cultural background Electricity is introduced as a subject of teaching at the fourth grade of elementary school. The topic is presented in a very descriptive and concrete form at this stage. The educator's aspiration is to encourage pupils to construct knowledge which: (1) allows correct practical use of simple electrical devices, (2) implants very basic ideas (such as closed circuit, electrical flow, electrical source) regarding the nature of electricity in its scientific though simplified form of continues flow, (3) introduces the fundamental notions of circuit, battery, current, electricity consumers, even without their precise definitions, and (4) encourages the construction of concepts (mental models) of electricity (such as electricity flow), which albeit being simplified, can serve as a basis for further learning and refinement at higher levels of education.The present understanding of learning was agreed on to be known as constructivism educational theory (e.g., Tobin, 1993) recognizing the central role of learners' own spontaneous ideas on the subject of instruction (as well as regarding the nature of science and its epistemology). These strongly interact with the presented knowledge and determine the results of the process of learning. Addressing learners' ideas about the topic being taught, thus stipulates success of the process. In this study
