Determine the Extent to Which the Next Generation Science Standards (NGSS) Are Incorporated into the Tenth-Grade Chemistry Textbook Used in Secondary Schools in the Republic of Yemen

Abstract

The current study aims to determine the extent to which the Next Generation Science Standards (NGSS) are incorporated into the tenth-grade chemistry textbook used in secondary schools in the Republic of Yemen. The study followed the descriptive and analytical approach, because it is the approach that suits the nature of the study and its second objective. The study population consisted of a chemistry textbook and a booklet of activities and laboratory experiments for the tenth grade of secondary school in the Republic of Yemen. The study sample included (100%) ) of the study population, and the study tool at this stage was the content analysis tool.

The study yielded the following results:

1. The list of science standards for the second generation NGSS, and their proposed indicators, for the field of matter and its interactions, consisted of (8) standards, (24) dimensions, (29) axes, (32) criteria, and (409) indicators.


2. It was found that the overall average extent to which the second generation science standards (NGSS) include the field of matter and its interactions in the content of the chemistry book, and the booklet of laboratory activities and experiments; For the tenth grade of secondary school in the Republic of Yemen, it is equal to (0.83), with a low degree of inclusion.

In light of the limitations of the problem of the study, its questions, importance and results; The study recommends examining the experiences of countries that preceded us, especially the American experience. Because it summarized the experiences of 25 years of work with educational standards In light of the limitations of the problem of the study, its questions, importance and results; The study recommends examining the experiences of countries that preceded us, especially the American experience. Because it summarized the experiences of 25 years of work with educational standards. It also can be suggested that several studies be conducted; To complement aspects of the current study.
