Developing the Content of Science Books in the Preparatory Stage According to the Next Generation of Science Standards (NGSS) for the Dimension of Central ideas

Abstract

The primary purpose of the research was to develop material for science textbooks in accordance with the Next Generation Science Standards for the preparatory level. The researcher relied on the calculation of frequencies, percentages, and averages to include standards and indicators of the field of physical sciences in science books for the preparatory stage. This gave the researcher a way to figure out how much of the content of science books (like the parts on physics) was relevant to the field of physical sciences. The researcher analyzed the content of the books in the study sample for the two semesters that took place during the academic year 2021–2022, using the analytical descriptive research method. The collection and analysis of data relied on content analysis, which was prepared in light of the Next Generation Science Standards (NGSS). The scientific standards for the discipline of physical sciences included one main notion (physical sciences), four more specific concepts, and 11 indicators. The findings led researchers to the conclusion that the fundamental ideas of the standard for physical sciences achieved an average percentage of the sub-ideas, including 44%, motion, strong stability, and interactions 25%, energy 25%, and waves and their technological applications 6%; this indicates a low level of inclusion, which suggests that there is a need for improving the content of science books for the preparatory level.
