Evaluating the relevance of the content of the experimental science textbooks of the primary schools with different orientations of the basic sciences

The general purpose of this study was to analyze the content of elementary science textbooks in terms of relation with different orientations in basic sciences. The research method is descriptive and of content analysis type. The statistical society consisted of all science textbooks in the first and second primary courses and the entire statistical society was considered as an example. In this research, addition to analyzing the data at the descriptive statistics level, Shannon entropy content analysis method was used to evaluate four fundamental sciences trends including physics, chemistry, biology and geology. The unit of text analysis is visual and written subjects and the reliability of the research tool has been confirmed. The results of the Shannon analysis show that of a total of 1,628 units recorded for visual subjects, the highest information load related to biology (0.99) and of 5940 recorded items for written subjects, the highest information load was on biology and geology tendencies (0.96).
