Alignment of Chemistry Textbooks for the Ninth and Tenth Grades in Jordan with Scientific and Engineering Practices (SEPs)

This study aimed to investigate the extent to which chemistry textbooks for the ninth and tenth grades in Jordan align with scientific and engineering practices in light of the Next Generation Science Standards (NGSS).The study followed a descriptive-analytical approach and developed a content analysis tool based on the dimension of scientific and engineering practices according to the original NGSS document, and its psychometric properties were verified.The sample consisted of the chemistry textbooks for the ninth and tenth grades, in both parts (first and second).The results revealed that the inclusion of the dimension of scientific and engineering practices in the content of chemistry textbooks was low across all practices, except for the practice of "analyzing and interpreting data," which was moderately represented in both the ninth and tenth grades.The study recommended reconsidering the questions and scientific activities included in the chemistry textbooks for the ninth and tenth grades in Jordan to ensure a balanced and diversified inclusion of scientific and engineering practices.
