News media,social media,and hyperlink networks: An examination of integrated media effects

Research typically focuses on one medium. But in today's digital media environment, people use and are influenced by their experience with multiple systems. Building on media ecology research, we introduce the notion of integrated media effects. We draw on resource dependence and homophily theories to analyze the mechanisms that connect media systems. To test the integrated media effects, we examine the relationships between news media visibility and social media visibility and hyperlinking patterns among 410 nongovernmental organization (NGO) websites in China. NGOs with greater news media visibility and more social media followers receive significantly more hyperlinks. Further, NGOs with a similar number of social media followers prefer to hyperlink to each other. The results suggest that both news media and social media systems are related to the configuration of hyperlink networks, providing support for the integrated media effects described. Implications for the study of hyperlink networks, online behaviors of organizations, and public relations are drawn from the results.     

Evaluating Teacher-Leaders for Careers as Administrators: Effects of Job Attributes, Teacher Leader Role, and Teaching Assignment Area

Recruitment of public school administrators is an important issue due to the shortage of qualified job applicants nationwide. The shortage of applicants requires school districts to evaluate their internal pools of potential applicants for administrative vacancies. This evaluation research addressed the recruitment of teacher-leaders to serve as assistant principals (APs) using a recruitment simulation technique. The participants were secondary school teacher-leaders who were counselors, school council members, department chairs, or resource teachers. The evaluation technique used involved an innovative experimental design approach. Teacher-leaders, whose current or past primary teaching assignment was in the core content areas (e.g., English/language arts, mathematics, science, social studies), rated the job of AP highest. Resource teachers rated the job significantly higher when the AP job emphasized instruction than when the job emphasized discipline. Implications for recruitment practice and future research are discussed.     

亲爱的木木，我们开始认真了

春天总是过得异常快，刚下过几场雨。就已经快三月了。雨还在吧嗒吧嗒地下着，不过再也不用叫醒木木了。毕竟快高考了，谁还会再在课堂上睡觉呢？木木，也许再陪你听过几场雨，就会到那个绵长绵长的六月了吧？     

Infusing Culturally Responsive Instruction to Improve Mathematics Performance of Latino Students with Specific Learning Disabilities

Culturally responsive instruction has the advantage of helping diverse students make academic gains. The purpose of this study was to investigate the effects of culturally infused mathematics lessons on the academic achievement of five middle school Latino students with specific learning disabilities in a resource classroom. We used an ABACACA multiple treatment reversal design, in which two forms of culturally responsive instruction (B) and its modification (C) were compared with the traditional instruction (A). The results of the study indicated that the modified culturally responsive mathematics instruction (C) was associated with increases in positive gains in participants' daily mathematics quizzes. Limitations and implications are discussed in relation to culturally responsive instruction for middle school Latino students with specific learning disabilities.     

The Effects of the Number of Scale Points and Non-Normality on the Generalizability Coefficient: A Monte Carlo Study

Increasingly, assessment practitioners use generalizability coefficients to estimate the reliability of scores from performance tasks. Little research, however, examines the relation between the estimation of generalizability coefficients and the number of rubric scale points and score distributions. The purpose of the present research is to inform assessment practitioners of (a) the optimum number of scale points necessary to achieve the best estimates of generalizability coefficients and (b) the possible biases of generalizability coefficients when the distribution of scores is non-normal. Results from this study indicate that the number of scale points substantially affects the generalizability estimates. Generalizability estimates increase as scale points increase, with little bias after scales reach 12 points. Score distributions had little effect on generalizability estimates.
