Blocking between landmarks during 2-D (touchscreen) and 3-D (ARENA) search tasks with pigeons

Many studies investigating cue competition have focused on the blocking effect. We investigated the blocking effect with pigeons using a landmark-based spatial search task in both a touchscreen preparation (Exp. 1a) and an automated remote environmental navigation apparatus (Exp. 1b). In Phase 1, two landmarks (LMs: A and Z) appeared on separate trials as colored circles among a row of eight (touchscreen) or six (ARENA) identical response units. Subjects were rewarded for pecking at a target response unit to the right of LM A and to the left of an extraneous LM, Z. During the blocking trials in Phase 2, LM X was presented in compound with a second LM (A) that had been previously trained. On control trials, LM Y was presented in compound with LM B and a target in the same manner as in the trials of AX, except that neither landmark had previously been trained with the target. All subjects were then tested with separate trials of A, X, B, and Y. Testing revealed poor spatial control by X relative to A and Y. We report the first evidence for a spatial-blocking effect in pigeons and additional support for associative effects (e.g., blocking) occurring under similar conditions (e.g., training sessions, spatial relationships, etc.) in 3-D and 2-D search tasks.     

Where is it? How deaf adolescents complete fact-based internet search tasks

An exploratory study was designed to describe Internet search behaviors of deaf adolescents who used Internet search engines to complete fact-based search tasks. The study examined search behaviors of deaf high school students such as query formation, query modification, Web site identification, and Web site selection. Consisting of two fact-based search tasks, the study was done in four regional day school programs for the deaf. As students conducted two search tasks, they completed task analyses of the selected Web sites and gave reasons for their selections. The research also identified the processes used by deaf students to compensate for limited English reading abilities while navigating search engines results that were typically written well above deaf students' average reading level. The results demonstrated that deaf adolescents were unable to initiate, conduct, analyze, or validate effective Internet searches in response to fact-based search tasks.     

Non-traditional students in tertiary education: inter-disciplinary collaboration in curriculum and pedagogy in community services education in Australia

Education policy in Australia has accelerated its aim to increase participation of under-represented groups in tertiary education including students who are culturally and linguistically diverse and have low socio-economic status. These students generally have not had prior access to privileged academic discourse, which can further disadvantage them in their participation and progress in tertiary education. In this article, we outline a cross-discipline curriculum initiative and pedagogy that draws on critical literacy and the metaphor of discourse community to integrate language and academic skills into community services qualifications. We argue that this – supports the genuine participation of under-represented (non-traditional) students. It aspires to not only support students’ entry into the new academic terrain, but to enable students to adopt a critical stance to the discourses in which they are learning to participate. This we argue is crucial, when expertise is not just a way of meeting its ostensible purposes, but is also a way of exercising power. Although we report on the application of this initiative to entry level curricula (Diploma), we suggest that it has relevance and application to Bachelor levels in a range of disciplines, both in supporting pedagogy and for transition to Bachelor level study.     

Supporting new school leaders: findings from a university‐based leadership coaching program for new administrators

Administrators need intense support in their early years in their jobs to master the demands of the position and to emerge as effective leaders for their schools. This article reports on a leadership coaching program offered by a university to support graduates as they transition to new school leadership roles. First year research results of the Program for New Principals indicate that all of the program participants felt that the coaching program was a positive addition to the induction experience for new administrators. New principals viewed coaching positively and emphasized that it is both a valuable and unique form of professional development. Both coaches and new principals cited personalized support as one of the coaching model's most significant assets. The results should inform the development of a model of leadership coaching for new administrators.     

Using Gestalt theory to teach document design and graphics

Gestalt psychology principles of figure‐ground segregation, symmetry, closure, proximity, good continuation, and similarity provide a simple yet powerful analytic vocabulary for discussing page layout and graphics. The six principles apply readily to typography, white space, data tables and maps, the relation between graphics and text, and other facets of textual design. The principles explain many difficulties that readers have in processing texts and graphics, and they explain why well‐designed pages and graphics are effective.
