A Review of the Health System Development Components in the Science Curriculum in Primary Schools: Shannon's Entropy Technique

The Health System Development document is one of the leading documents in the field of health planning that will guide the activities of country's health care until 1404. Health education is among the important areas that are considered in the development of the health system. This study aimed to analyze the content of the science books of the elementary schools based on the components related to education in the documents of health system development. It will help to determine the level of attention to these components in elementary textbooks. This descriptive study was performed by content analysis method using Shannon entropy technique. In this technique, first, the frequency of each component was determined in the desired content. In the second step, the frequencies converted into normal data and frequency and importance coefficient were calculated for each of the indicators and components including health, accidents, prevention and nutrition. The importance coefficient for nutritional health component (0.308) was more than other components and preventive component had the least value of importance coefficient (0.114).
Among the other indicators, the nutritional health (0.191), physical health had the highest importance coefficient (0.189) while the importance coefficient for the prevention of high-risk behavior was computed zero. The results of this study showed that among all the pages of the experimental sciences books, the elementary school has focused on the components of nutrition and health (physical, family, psychological, and environment) more than others. Preventive component had the lowest attention.
