Teacher Evaluation, Leadership and Learning Organizations

This article presents the argument that meaningful teacher evaluation in schools can be an important catalyst for organizational learning and school improvement when it is linked to broader conceptions of leadership in schools. A state-of-the-art teacher evaluation, assessment and professional growth system is described and the manner in which this system is linked to leadership density, organizational learning, and school improvement is detailed. Findings from two contrasting case studies of schools implementing this new system are presented and implications of the findings for linking teacher evaluation systems, newer conceptions of school leadership, and school improvement are described.     

Developing cultural competency in higher education: an agenda for practice

As a result of changing national values and unrest, demographic and population shifts, and ever-changing admissions practices and policies, implementing a diversity and cultural-competency agenda within university settings has become a priority across the UK, Europe, and US. Furthermore, public institutions across the UK, EU, and US are now more racially and ethnically diverse than ever [Snyder, T. D., C. Debray, and S. A. Dillow. 2016. ‘Digest of Education Statistics 2016.’ NCES 2016-006. National Centre for Education Statistics; Sursock, Andree. 2015. Trends 2015: Learning and Teaching in European Universities. European University Association. Accessed October 28 2017. www.eua.be/Libraries/publicationshomepage-list/EUA_Trends_2015_web.]. Yet, cultural competency efforts on campuses remain largely under theorized [Bezrukova, K., K. A. Jehn, and C. S. Spell. 2012. “Reviewing Diversity Training: Where We Have Been and Where We Should Go.” Academy of Management Learning and Education 11 (2): 207–227] and diffuse [Sue, S., D. C. Fujino, L. T. Hu, D. T. Takeuchi, and N. W. Zane. 1991. ‘Community Mental Health Services for Ethnic Minority Groups: A Test of the Cultural Responsiveness Hypothesis.’ Journal of Consulting and Clinical Psychology 59 (4): 533–540]. This article seeks to outline an agenda for this work, highlighting outcomes of cultural competency learning and underscoring the role of campus leadership in the development of supportive characteristics. These characteristics include attention to shared knowledge, professional learning at all levels of the organization, inclusive instructional methods, integration with other campus initiatives, and inclusivity of diversity foci. Posited are six supportive conditions for successful implementation.     

用改进的元胞自动化模型模拟不同信号灯控制策略下的交通流

Traffic flows controlled by traffic light strategies were investigated via a cellular automaton model with anticipation, which is suitable for describing urban traffic. Three kinds of strategies, i. e., synchronized, green-wave and random switching lights, were designed, simulated and compared with each other. It is shown that the green-wave strategy is only valid at lower density and there is not an effective way with the three strategies to improve the efficiency of traffic flow at high density.     

The linguistic construction of expert identity in professor–student discussions of science

This study examines how participation in a verbal exchange during an inquiry-based classroom activity allows three college students and their science instructor to use linguistic signs (choices of words, grammatical structures, discursive structures, prosody and poetic discourse) to construct authority and expertise. Our work explores linguistic and interactional processes of identification (the dynamic construction and transaction of expert identity) and examines how discursive strategies adopted by the professor at different moments of the verbal exchange influence the students’ subsequent discursive practices and perceptions of authority. We adopt a dialogic, socio-constructivist perspective on identity, viewing personal identities as being partially constructed via interactional positioning. Our findings reveal that the attainment of expertise involves two different types of language-mediated processes: the transmission of a professional vision or intension and the emergence of a perception of agency among students. The former is centered on referential-denotative meanings of speech (elicitation of standard account and operational definition) while the latter requires effective use of pragmatic–performative functions of speech (non-evaluative and more than minimal recipient practices). Consideration is given to the need for science instructors to be able to utilize pragmatic functions of language strategically to encourage students to position themselves within the identity of science expertise.     

Reward and ideational fluency in preschool children

This study examined the effects of rewards on the ideational fluency of 75 preschool children. Assigned to a reward or nonreward condition, the children were administered two ideational fluency tasks, Unusual Uses and Pattern Meanings. Analyses revealed a significant main effect for reward on the ideational fluency components of originality, total fluency, and flexibility. In all cases the rewarded subjects scored lower than the nonrewarded group. These findings support the growing body of evidence that rewards are detrimental to creative functioning.     

Curious sex ratios and cytoplasmic genes

Evolutionary theory predicts that most populations should consist of roughly as many males as females. Recently, a variety of populations have been described which show very different proportions of the two sexes, especially in invertebrate species that contain individuals whose offspring are almost all female. Some of these instances can now be explained by the diverse actions of various ‘selfish’ elements residing in the cytoplasm of the individuals, which are transmitted exclusively through the female line. These instances of curious sex ratios exemplify an important principle: the fitness of genes, rather than of individuals, is the primary currency of evolution.     

Engaging by design: How engagement strategies in popular computer and video games can inform instructional design

Computer and video games are a prevalent form of entertainment in which the purpose of the design is to engage players. Game designers incorporate a number of strategies and tactics for engaging players in “gameplay.” These strategies and tactics may provide instructional designers with new methods for engaging learners. This investigation presents a review of game design strategies and the implications of appropriating these strategies for instructional design. Specifically, this study presents an overview of the trajectory of player positioning or point of view, the role of narrative, and methods of interactive design. A comparison of engagement strategies in popular games and characteristics of engaged learning is also presented to examine how strategies of game design might be integrated into the existing framework of engaged learning.

The relation of parenting style to adolescent school performance

This article develops and tests a reformation of Baumrind's typology of authoritarian, permissive, and authoritative parenting styles in the context of adolescent school performance. Using a large and diverse sample of San Francisco Bay Area high school students (N = 7,836), we found that both authoritarian and permissive parenting styles were negatively associated with grades, and authoritative parenting was positively associated with grades. Parenting styles generally showed the expected relation to grades across gender, age, parental education, ethnic, and family structure categories. Authoritarian parenting tended to have a stronger association with grades than did the other 2 parenting styles, except among Hispanic males. The full typology best predicted grades among white students. Pure authoritative families (high on authoritative but not high on the other 2 indices) had the highest mean grades, while inconsistent families that combine authoritarian parenting with other parenting styles had the lowest grades.
