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.     

What Do We Teach When We Teach the Learning Sciences? A Document Analysis of 75 Graduate Programs

The learning sciences, as an academic community investigating human learning, emerged more than 30 years ago. Since then, graduate learning sciences programs have been established worldwide. Little is currently known, however, about their disciplinary backgrounds and the topics and research methods they address. In this document analysis of the websites of 75 international graduate learning sciences programs, we examine central concepts and research methods across institutions, compare the programs, and assess the homogeneity of different subgroups. Results reveal that the concepts addressed most frequently were real-world learning in formal and informal contexts, designing learning environments, cognition and metacognition, and using technology to support learning. Among research methods, design-based research (DBR), discourse and dialog analyses, and basic statistics stand out. Results show substantial differences between programs, yet programs focusing on DBR show the greatest similarity regarding the other concepts and methods they teach. Interpreting the similarity of the graduate programs using a community of practice perspective, there is a set of relatively coherent programs at the core of the learning sciences, pointing to the emergence of a discipline, and a variety of multidisciplinary and more heterogeneous programs “orbiting” the core in the periphery, shaping and innovating the field.     

Dialogic education as an approach to multiculturalism for social cohesion in Namibia

The paper explores approaches to cultural diversity and its relation to the concept of social cohesion in the context of a multicultural school community. It uses insights from an empirical research on multicultural education conducted in Namibia as context for a discussion on tools in educational practice that would support diversity while working towards a greater integration of a pluralistic society. Looking into the African concept of Ubuntu and the corresponding teachings of the philosophers of dialogue, this theoretical paper suggests dialogic learning as an approach to multiculturalism that can enhance tolerance among peoples and produce a society united through understanding.     

A study regarding the spontaneous use of geometric shapes in young children’s drawings

The studies regarding how the comprehension of geometric shapes evolves in childhood are largely based on the assessment of children's responses during the course of tasks linked to the recognition, classification or explanation of prototypes and models. Little attention has been granted to the issue as to what extent the geometric shape turns out to be an expressive tool that young children spontaneously use in their pictorial productions and also, whether or not methodological research approaches aimed at the examination of unprompted usage of geometric shapes in childhood may be useful regarding the study of the development of geometric thinking. This evidence provided by this study is coherent with the assumption that before starting primary education, internal representation of closed curves, quadrilaterals and triangles should have been developed by a significant number of children and, more interestingly, that young children’s graphical expressivity appears liaised to their skill to depict two-dimensional geometric shapes.     

‘They want more of everything’: what university middle managers’ attitudes reveal about support for off-campus doctoral students

Advances in technology and a shifting demographic of post-graduate students have resulted in a larger than ever number of off-campus PhD students. These students tend to be less satisfied than their on-campus counterparts with their candidature experience. Improving the current situation requires effort from multiple university stakeholders, including academic middle managers, who play a role in allocating resources and setting research training agenda. However, with the intensification of academic workload, academic managers might not view the support of off-campus PhD students as a high priority. This study investigates the attitudes of middle managers in a large Australian university concerning the provision of training and support to off-campus PhD students. The findings reveal that a complex interplay of discourses hinder the provision of support to off-campus PhD students. Implications for practice are discussed.     

A Model Food Entrepreneur Assistance and Education Program: The Northeast Center for Food Entrepreneurship

ABSTRACT: The Northeast Center for Food Entrepreneurship (NECFE) is a collaborative effort between Cornell Univ. and the Univ. of Vermont. NECFE uses a multi-institutional and regional collaboration approach, with specific expertise and necessary facilities and resources, to provide technical assistance and education for businesses in the food industry. The overall goals of NECFE are to support and sustain rural businesses and promote sustainable economic development of rural communities. Through process evaluation techniques, the evaluators of NECFE identified 5 essential components of a model food entrepreneurship assistance and education center, based on NECFE's experience: (1) multi-institutional and regional collaboration, (2) expertise, (3) facilities and resources, (4) services, and (5) evaluation of the center. These components build on each other and enable NECFE to provide clients with access to current food processing technology, technical information, and education that are directly applicable to a real business. Through replication of this model, other organizations and academic institutions may establish a regional food entrepreneurship assistance and education center.

Three-dimensional kinematic analysis and power output of elite flat-water kayakers

The purpose was to examine power output and three-dimensional (3D) kinematic variables in the upper limbs, lower limbs and trunk in elite flat-water kayakers during kayak ergometer paddling. An additional purpose was to analyse possible changes in kinematics with increased intensity and differences between body sides. Six male and four female international level flat-water kayakers participated. Kinematic and kinetic data were collected during three tasks; low (Int_L), high (Int_H) and maximal (Int_M) intensities. No differences were observed in any joint angles between body sides, except for shoulder abduction. Significantly greater range of motion (RoM) values were observed for Int_H compared to Int_L and for Int_M compared to Int_L in trunk and pelvis rotation, and in hip, knee and ankle flexion. The mean maximal power output was 610 ± 65 and 359 ± 33 W for the male and female athletes, respectively. The stroke frequencies were significantly different between all intensities (Int_L 59.3 ± 6.3; Int_H 108.0 ± 6.8; Int_M 141.7 ± 18.4 strokes/min). The results showed that after a certain intensity level, the power output must be increased by other factors than increasing the joint angular RoM. This information may assist coaches and athletes to understand the relationship between the movement of the kayaker and the paddling power output.     

How does innovative continuous professional development (CPD) operate in the ECEC sector? Insights from a cross-analysis of cases in Denmark,Italy and Poland

This article offers insights into what characterises innovative continuous professional development (CPD) in the field of early childhood education and care (ECEC) by analysing similarities and differences from case studies of exemplary approaches to innovative CPD in Denmark, Italy and Poland. The comparative analysis focuses on four features that are particularly relevant for innovation in CPD in the field of ECEC: the social dimension of innovation as a strengthening component; the benefit of dynamic learning processes aimed at integrating theory and practice; the role of key figures in the quality of CPD; and measurements of CPD impact, outcomes and sustainability. This analysis sheds light on the effects of dynamic factors (e.g., regular team-based reflection sessions based on documentation and observation), the importance of work conditions (e.g., contractual obligations to provide time for reflection), the critical role of pedagogical leaders (coordinators, principals and head teachers, supervisors), the importance of inter-organisational networking at a local level and the facilitating role of collaboration with research institutes.
