The use of relative and absolute bearings by Clark’s nutcrackers,Nucifraga columbiana

Two groups of Clark’s nutcrackers were trained to find buried seeds whose location was defined by a constant angle from two landmarks whose interlandmark distance and position in the room varied across trials. The first group had a landmark array that was always placed in the same orientation with respect to the walls, allowing the animals to use both relative and absolute bearings. The second group had a landmark array that rotated across trials so that only relative bearings could be used to locate the seeds. The birds in each group learned the task and transferred to new interlandmark distances both within and beyond the range of training distances. Results from these experiments indicate that nutcrackers can learn a geometric relationship that relies exclusively on relative bearings even though the use of absolute bearing yields more efficient search.     

BEGINNING PREKINDERGARTEN AND KINDERGARTEN TEACHERS’ BELIEFS AND PRACTICES: SUPPORTS AND BARRIERS TO DEVELOPMENTALLY APPROPRIATE PRACTICES

This study explores the beliefs and practices of nine beginning prekindergarten and kindergarten public school teachers and identified the sources of supports and barriers to their teaching. The teachers were graduates from one university's early childhood education program. Data were gathered using surveys, observations, and interviews. Overall, teachers professed to believe in and to use developmentally appropriate practices; they were also observed using more developmentally appropriate practices than developmentally inappropriate practices. Teachers reported a variety of sources of support and barriers to their teaching. Sources that were both supports and barriers were administration, co‐workers, curriculum requirements, parents, resources, and other. Sources reported only as supports were previous experiences, self, and continued education. Sources of barriers were class composition and school duties. In addition, teachers provided information about their teacher education program and on their expectations about teaching. The teachers suggested that teacher education programs needed to provide more field experiences and courses on classroom management. Some of the expectations the teachers had about teaching were unrealistic.     

Enhancing Alphabet Knowledge Instruction: Research Implications and Practical Strategies for Early Childhood Educators

Alphabet knowledge is consistently recognized as the strongest, most durable predictor of later literacy achievement. Recent research offers practical implications for increased effectiveness of teaching alphabet knowledge to young children. In this article, we outline Enhanced Alphabet Knowledge instruction (EAK), a method of practical instruction that early childhood teachers can use to organize, plan, and teach the essential skills of alphabet knowledge. EAK emphasizes identifying the letter name and sound, recognizing the letter in text, and producing the letter form, through flexible, distributed cycles of review based on factors that influence acquisition of alphabet knowledge.     

Ebony in the Ivory Tower: Examining Trends in the Socioeconomic Status,Achievement, and Self-Concept of Black,Male Freshmen

Despite the educational challenges African American males face, there is a sizeable population successfully finishing high school and entering college. This study provides an overview of how a national sample of black male freshmen embodied the cognitive, social, and institutional factors related to college access between 1971 and 2004. Data reveal that black, male freshmen today have more affluent family backgrounds, better academic records, and greater confidence in their skills and abilities than their peers who entered college in earlier decades. Trends indicate that men with lower incomes, less confidence, and less ideal academic records are increasingly unlikely to be present on college campuses.     

Traditional governance structures ‐ current policy pressures: The academic senate and Canadian universities

Abstract

The objective of this paper is to identify current policy pressures in Canadian higher education and explore their implications for academic decision‐making bodies based on data we obtained in our national study on university senates. We describe two inter‐related sets of public policy pressures that have emerged in recent years in Canada including on‐going financial restraint and a renewed interest in university research. We conclude by reviewing a number of important implications for Canadian university governance in the context of contemporary policy pressures.
