Gender gaps in STEM fields have been studied for a long time, and the primary focus has been on the relationship among social support (parents and teachers), STEM beliefs (STEM interest belief, self‐efficacy belief, and value belief), and STEM career expectations. Framed in Expectancy‐Value Models, this article aimed to explore how social support affects students' STEM career expectations directly and indirectly through STEM beliefs. Further, a gender study was conducted to examine the differences in structural relations between male and female student groups using multiple‐group structural equation modeling. A total of 798 10th grade students were surveyed in mainland China. The results showed that (1) male students performed better than female students in STEM career expectations, STEM value beliefs, STEM self‐efficacy beliefs, as well as parents' and teachers' support; (2) female students' STEM career expectations could be predicted by parental support, STEM value beliefs, and STEM interest beliefs, while male students' STEM career expectations were positively influenced by parental support, STEM self‐efficacy, and STEM interest beliefs. Hence, there were apparent gender differences regarding STEM interest beliefs, STEM self‐efficacy and their relationship toward future career expectations. Specifically, STEM interest beliefs were positively correlated with STEM career expectations of female students, whereas STEM self‐efficacy could only significantly influence male students' STEM career expectations.
The content of physics textbooks has always been an important part of physics education research. This chapter systematically reviewed the empirical studies on the contents of physics textbooks from the 1940s to 2022. The brief history and development of research was outlined, and representative research was identified. This chapter reviewed the contents from conceptual, epistemic and cultural levels and the representations of contents in physics textbooks. This chapter also investigates how different content analysis methods contribute to the issues of physics textbooks within the science education community from the methodology perspective. The findings show the researchers' continuous efforts on improving the validity of concepts and readability of texts, growing attentions on nature of science, argumentation and equal issues of hot topics in science educational research. The implications for future research are provided, including the use of new technologies to examine the content of physics textbooks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
