Multiple-pair training enhances transposition in pigeons

We studied transposition in pigeons by training them to select the smaller (or the larger) of a pair of circles. In training, different groups of pigeons were given one pair, two pairs, or three pairs of circles along the size dimension. Testing included two stimulus pairs for which, according to theoretical postdiscrimination generalization gradients, transposition should decrease from one-pair to two-pair to three-pair training. On the basis of the results of our earlier study (Lazareva, Wasserman, & Young, 2005) and contrary to these predictions, we expected that transposition should increase from one-pair to two-pair to three-pair training. We found that multiple-pair discrimination training enhanced transposition, which, on average, rose from 47% (one-pair training) to 52% (two-pair training) to 64% (three-pair training). In addition, we found that the overall similarity of the testing pair to the training pair(s) modulated the strength of relational responding. These results demonstrate that encountering multiple instances of a rule leads to stronger relational learning, even when reinforcement history predicts the opposite trend. These results also provide strong evidence against stimulus generalization as the sole determinant of relational responding in transposition.     

The protective effects of religiousness and parent involvement on the development of conduct problems among youth exposed to violence

This study examined the protective effects of religiousness and parent involvement for the development of conduct problems beyond the effects of risk factors. Measures of violence exposure, conduct problems, parent involvement, and religiousness, from the longitudinal Social and Health Assessment survey, were completed by 1,703 high-risk urban adolescents (12.5 +/- 1.7 years; 53% female). Witnessing of and victimization by community violence appeared to be significant risk factors for an increase in conduct problems over a 1-year period. Religiousness and parental involvement were each uniquely associated with a decrease in conduct problems. Moreover, several dimensions of religiousness moderated the relationship between violence exposure and conduct problems, buffering the negative effects of violence exposure. Implications of these findings for prevention efforts are discussed.     

Academic Administrators’ Beliefs About Diversity

As our nation and society becomes more racially and ethnically diverse, college campuses are experiencing a dynamic shift in the student demographic on campus as well. Purposes of the study were to: (a) analyze the beliefs of kinesiology academic unit leaders (i.e., chairs, directors, heads) regarding faculty and student diversity within their programs and departments and (b) inquire about strategic goals for faculty and student diversification within their programs and departments. The participants were 68 administrators (43 men, 25 women) and all current members of the American Kinesiology Association (AKA) as of 2015. Thematic content data analysis of the open-ended probes exposed the recurrent themes: (a) advocacy, motives, and actions; (b) diversity identified, but rarely defined; and (c) history, status, and outlook. Implications of the findings are that issues associated with diversity in kinesiology programs and departments should be addressed with vigor and progressive actions.     

Gender balance in teaching awards: evidence from 18 years of national data

Gender implications of nationally competitive teaching awards were examined to determine whether women receive sufficient accolades, given their dominant position in university teaching. Quantitative methods and secondary data provided objective analysis of teaching awards for Australian universities, for an 18-year data set with 2046 units of analysis. Results indicate that women were over-represented in lower-level citations and under-represented in higher-level awards. Women did not dominate, particularly the highly prestigious Prime Minister’s award, where men constituted 65%. Policy and management implications include that universities could review the gender balance in their teaching award processes and set goals as internal support is a springboard to national awards. Groups of the same gender could be encouraged to work together at the highest levels to overcome individualistic, competitive barriers. National teaching award applications could be gender blind, at least for the higher levels. There are no clear trends towards a better gender balance, possibly because there has been a very limited gender spotlight on the awards at any level of policy and management.     

Activity theory in empirical higher education research: choices,uses and values

This paper contributes to discussion of theory application in higher education research. We examine 59 empirical research papers from specialist journals that use a particular theory: activity theory. We scrutinise stated reasons for choosing the theory, functions played by the theory, and how the theory is valorised. We find that the theory is usually chosen for its direct empirical applicability; used for abstraction, explanation and contextualisation; and valorised for apprehending complex situational dynamics. It is rarely chosen to challenge conceptualisation of the research object; used to establish investigative paradigms; or valorised in ways that implicate wider bodies of knowledge or potential theory development. We argue that higher education researchers should reconsider how their application of activity theory is interwoven with interpretative processes, how the theory might frame research design rather than simply data analysis, and how they account for the range of roles that the theory actually plays across research endeavours.     

Social mapping and environmental education: dialogues from participatory mapping in the Pantanal,Mato Grosso,Brazil

Abstract

This article illustrates the steps taken to enact a new methodology for participatory social mapping by the Environmental Education, Communications and the Arts (GPEA) Research Group of the Federal University of Mato Grosso (UFMT). The aim of Social Mapping is to record the identities, territories and socio-environmental conflicts experienced by social groups, based on their own namings and narratives, rather than relying on those more typically generated or provided by researchers or theorists. As such, it offers an important dialogical pathway for environmental education practices, in that it highlights the intrinsic relationship between culture and nature, and reinforces the understanding that the loss of one implies the disappearance of the other.     

物质,反物质,万物之源

Scientists in Europe made an incredible announcement:they had produced not one,but tens of thousands of“anti-atoms,”atoms made entirely of antimatter.Thisresult rightly generated a good amount of publicity,butI was amused at the media’s reaction to the news.Whenever Isaw it mentioned,either on television or in papers,there al-ways seemed to be a picture of the starship Enterprise or someother science fiction-type image.     

Australian teachers voice their perceptions of the influences of stereotypes,mindsets and school structure on teachers’ expectations of Indigenous students

Research demonstrates that teachers’ expectations of students have long-term effects on students’ educational, occupational, health and well-being outcomes. In this Australian-based study, teachers were invited to explore the questions Do teachers have different expectations of Aboriginal and Torres Strait Islander students? Why/why not? The findings provide insight into how teachers perceive the expectations of other teachers in relation to Indigenous learners and highlight the underlying assumptions of those perceptions. Teachers also provide valuable insight into what they feel is needed to address these issues. Recommendations are made to enhance pre-service teacher education and professional development to better support those working with Indigenous learners.     

Connected and culturally embedded beliefs: Chinese and US teachers talk about how their students best learn mathematics

This study compares US and Chinese elementary mathematics teachers' beliefs about how students learn mathematics. Interviews with teachers in each country revealed that Chinese and US teachers have distinct ways of thinking about how mathematics should be taught and how students learn. Many Chinese teachers talked about developing students’ interest in mathematics and relating the content of mathematics lessons to real-life situations. The US teachers talked about students' learning styles and using hands-on approaches to learning mathematics. Furthermore, these beliefs may be widespread and persistent within each country because the set of ideas among teachers appear to be internally consistent. Implications for teacher change and the study of teachers' beliefs are discussed.
