1. Examining Factors That Influence the STEM Career Choices of Secondary School Students: Using Data from TIMSS 2019 Daiki Nakamura (Hiroshima University)
2. Introduction: Demand for STEM Workforce 2 ⚫ U.S. Bureau of Labor Statistics employment projections for 2019-29 (Zilberman & Ice, 2021) STEM occupations : +8.0% All other occupations : +3.7% The demand for STEM workforce is increasing ⚫ The gap between supply and demand for STEM workforce ➢ EU • 40% EU employers said in 2013 that they have difficulty finding the right skills when recruiting (Cedefop, 2018). ➢ Japan • There is a shortage of STEM workforce to meet the demand of companies (METI, 2018). We need to increase the number of people choosing STEM careers to close these gaps.
3. STEM Career Choice Models: Self-Efficacy Model 3 ⚫ Self-Efficacy Model (Bandura, 1977; Hackett & Betz, 1981) Self-Efficacy Choice Goals Self-Efficacy: Confidence in job-related areas. Choice Goal: Aspirations of what career choice to make. ◆Lent et al. (1986) Self-efficacy predicts science and technology career aspirations. ◆Nauta et al. (1998) Self-efficacy influences higher-order science career aspirations. What are the psychological mechanisms by which young people choose their careers?
4. STEM Career Choice Models: Social Cognitive Career Theory (Choice Model) 4 ⚫ Social Cognitive Career Theory (SCCT: Lent et al., 1994, 2000) Self-Efficacy Interest Outcome Expectations Choice Goals Learning STEM will be useful in future careers. Supports & Barriers • Parents’ expectations • Parents' educational background • Socioeconomic status (SES) I am confident that I can understand the content of STEM fields.
5. STEM Career Choice Models: Social Cognitive Career Theory (Choice Model) 5 ⚫ Social Cognitive Career Theory (SCCT) Meta-analysis by Lent et al. (2018) Integrating 143 studies on STEM careers. # 84% of the data is from the US. Generalization possible?
6. Purpose and Method 6 This study aims to find how the SCCT fits in different countries. ⚫ Purpose ⚫ Method ➢ Data Data from 8th grade students in Japan, Korea, Taiwan, the United States, and the United Kingdom in the TIMSS 2019 survey. *Teenage career aspirations predict career attainment in adulthood (e.g., Schoon, 2001). ➢ Analysis • Path analysis for data from different countries. • Checking for goodness of fit. • Estimation of direct and indirect effects.

10. Discussion 10 ⚫ It is important to build confidence in students through science education that focuses on understandability. (i.e., Self-efficacy) ⚫ It might be important to show them how learning science can be useful in STEM careers. (i.e., Outcome expectations) ⚫ SCCT fit the data not only for the United States, but also for East Asian regions. ⚫ Self-efficacy (β=.203–270) and outcome expectations (β=.646–.857) influence STEM career choice.

11. Limitations and Future Challenges 11 ⚫ This study did not address the hierarchical nature of the TIMSS data. ➢ Multilevel model ⚫ Did not measure broad career aspirations in STEM fields. ➢ Increase the number of measurement items and improve the validity. ⚫ The effectiveness of the intervention on self-efficacy and outcome expectations is unknown. ➢ Longitudinal intervention studies

13. How Improve Outcome Expectations for STEM Careers? 13 ⚫ Reinhold et al. (2018), Drymiotou et al. (2021) • Introduce science topics that are relevant to everyday life. • Connect with scientists or experts. • Provide information about STEM careers and pathways. ⚫ Projects in Japanese High Schools ➢ High school students participate in conferences and interact with experts. ➢ Experts in STEM fields to lecture at high schools.
