Description
This study investigated the current state of the U.S. and Chinese urban middle school math teachers' pedagogical content knowledge (PCK) for the topic of functions. A comparative, descriptive case study was employed to capture the PCK of 23 teachers in Arizona and of 28 teachers in Beijing, regarding their instructional knowledge, understanding of student thinking and curricular knowledge--three key components based on Shulman's conceptualization of PCK--related to functions. Cross-case comparisons were used to analyze the PCK of teacher groups across countries and socio-economic statuses (SES), based on the questionnaire, lesson plan, and interview data.
This study finds that despite cultural differences, teachers are likely to share some commonalities with respect to their instructional decisions, understanding of student thinking and curricular knowledge. These similarities may reflect the convergence in teaching practice in the U.S. and China and the dedication the two countries make in improving math education. This study also finds the cross-country differences and cross-SES differences regarding teachers' PCK. On the one hand, the U.S. and Chinese math teachers of this study tend to diverge in valuing different forms of representations, explaining student misconceptions, and relating functions to other math topics. Teachers' own understanding of functions (and mathematics), standards, and high-stakes testing in each country significantly influence their PCK. On the other hand, teachers from the higher SES schools are more likely to show higher expectations for and stronger confidence in their students' mathematical skills compared to their counterparts from the lower SES schools. Teachers' differential beliefs in students' ability levels significantly contribute to their differences between socio-economic statuses.

ABSTRACT
The purpose of this study was to investigate several factors associated with cyberbullying and its victims; gender, age, and the time spent using various forms of computer-mediated communication (CMC). Because cross-national studies are so important to understanding the similarities and differences found in this global problem, the current study explored the connection between traditional bullying and cyberbullying in middle school students in both the United States (N = 111) and Germany (N = 279). Participants ranged in age from 12 to 15 years and were administered self-report questionnaires during the regular school day. It was predicted that German students would have higher mean rates of CMC use; Americans would have higher mean rates of participation in and being victims of cyberbullying; there would be no mean differences in American and German student outcomes as either victims or perpetrators of traditional bullying. Results indicated that German students did use CMC more often than American students did, but Americans used certain forms of CMC more often, such as texting, IM and email. Contrary to expectations, Germans were more likely to participate in cyber and traditional bullying behavior. Americans did have a greater number of victims compared to perpetrators for both traditional and cyberbullying behavior. Additional results found that the American sample had a pattern of decreasing then increasing behavior as student age increased, across participation in all forms of bullying behavior, and participation rates often depended on the age of the students involved. Future research suggestions might focus on the importance of distinguishing the varying thought processes that define cyberbullying within a culture, specifically within our own culture. Additional research might also address how online communities and their inherent social norms and interactions, may inadvertently contribute to increasing cyberbullying and victimization of others outside of those groups and communities. Finally, due to the constant updating and improvement of social media, a follow- up study utilizing updated online applications would add considerably to the current knowledge base.
