Social media use in the career development of graduate students: the mediating role of internship effectiveness and the moderating role of Zhongyong

This paper proves that social media use can contribute in important ways to employability outcomes. Specifically, results from a survey of 196 recent graduate students in China indicate that social media use is positively related to employability skills. Internship effectiveness serve as a mediating mechanism through which social media use affects employability skills. Zhongyong has a moderating effect on the social media use-internship effectiveness relationship. In addition to the direct moderating effect, Zhongyong is found to moderate the indirect relationship between social media use and employability skills. We discuss implications of these results for research and practice.     

Teacher Beliefs in Action: A Cross-Sectional,Longitudinal Follow-Up Study of Teachers' Personal Practical Theories

Based on a cross-sectional, longitudinal follow-up study of graduates from our master's-level elementary education program, in this article we examined changes in espoused beliefs elicited in the form of personal practical theories (PPTs) of three graduates with 2, 4, and 6 years of experience teaching in the same partnership school where they did their student teaching. We compared their original PPTs collected during their teacher education program with their current PPTs elicited in follow-up interviews, and then observed their classroom practices. Case summaries of these teachers are presented, and analysis and implications focus on changes in their PPTs, how their PPTs played out in their classrooms, and perceived barriers and supports to enacting their beliefs.
