Home and Motivational Factors Related to Science-Career Pursuit: Gender differences and gender similarities

The purpose of the study was to examine whether gender differences exist in the mean levels of and relations between adolescents’ home environments (parents’ view of science, socio-economic status (SES)), motivations (intrinsic and instrumental motivations, self-beliefs), and pursuit of science careers. For the purpose, the Programmed for International Student Assessment 2006 data of Korean 15-year-old students were analysed. The results of the study showed that girls had lower levels of science intrinsic and instrumental motivations, self-beliefs, and science-career pursuit (SCP) as well as their parents’ values in science less than boys. Gender similarities, rather than gender differences, existed in patterns of causal relationship among home environments, motivations, and SCP. The results showed positive effects for parents’ higher value in science and SES on motivations, SCP, and for intrinsic and instrumental motivations on SCP for girls and boys. These results provide implications for educational interventions to decrease gender differences in science motivations and SCP, and to decrease adolescents’ gender stereotypes.     

Understanding Student Attempts to Find a Line of Fit

The least squares method of fitting a line is not one that naturally occurs to students. We present three tasks to understand student views on how lines may be fit.     

Education and labor market risk: Understanding the role of data cleaning

This paper examines whether conclusions about the relationship between education and labor market risk depend on the use of commonly applied procedures to clean data of extreme values. The analysis uses fifteen years of data from the Panel Study of Income Dynamics to demonstrate that conclusions about the relationship between education and labor market risk are sensitive to how extreme values of labor income are treated. The untrimmed estimates imply that college graduates experience 75% less transitory labor market risk than high school dropouts. However, applying commonly used trimming procedures results in estimates of a one standard deviation transitory labor market shock for high school dropouts being reduced by between $2700 and $4500, or 14% and 24% of annual earnings. The results demonstrate that seemingly innocuous sample selection procedures can have substantive implications.     

Making citizens of the world: the political socialization of youth in formal mass education systems

Unique cross-national data on adolescents’ civic skills, knowledge, and political attitudes are used to examine the democratic processes of modern mass schooling, effects of national political systems, and patterns of youth political socialization in 27 nations. Compared to the generally weak reported effects on mathematics and reading achievement, we find robust effects of schooling on youths’ civics knowledge, skills, and attitudes. Secondly, there is empirical support for the importance of a supra-national political culture, beyond that of unique national cultures, in the political socialization of youth. Lastly, there is evidence of an emerging common polity among youth across nations. The results extend notions of the institutional influence of mass public schooling on the political socialization of youth.     

An Investigation of the Contingent Relationships Between Learning Community Participation and Student Engagement

This study examined the contingent relationships between learning community participation and student engagement in educational activities inside and outside the classroom using data from the 2004 administration of the National Survey of Student Engagement (NSSE). Results indicated that learning community participation was positively and significantly related to student engagement, both for first-year students and seniors. For some types of engagement, relationships were significantly stronger for seniors than for first-year students. Analyses also revealed there was substantial variability across institutions in the magnitude of the relationships between learning community participation and first-year students’ levels of engagement. Although institutional characteristics accounted for some of the variability across institutions, a substantial amount of the variability in engagement–learning community relationships remained unexplained.     

Linguistic and pedagogical considerations for teaching Portuguese to Spanish speakers

This research study examines the pedagogical considerations and linguistic challenges regarding teaching Portuguese to speakers of Spanish. That the Portuguese language is similar to Spanish presents a unique set of advantages and challenges to students and instructors. The study of this population of students has grown considerably since the 1980s, and most notably since the 2000s. Two unique and growing populations of Portuguese learners come into focus during this study—both native and heritage Spanish speakers. Their specific learning goals are analyzed in detail, particularly regarding what types of innovative linguistic methods and assessment strategies are relevant for these learners.
