Professional development design: Embedding educational reform in New Zealand

Teacher professional development variously supports ongoing skill development, new knowledge, and systems change. In New Zealand, the implementation of major assessment reforms in senior secondary schools provided opportunity to investigate teacher professional development as a function of the particular stage of an educational reform. Multi-method data sources including teacher surveys and school case studies were employed to evaluate professional development during the embedding stage of a standards-based assessment system, revealing a positive relationship between professional satisfaction and teacher involvement in setting priorities for the professional development. Other positive features were networking, personalized learning, and facilitator expertise. This research illustrates the importance of tailoring professional learning to implementation phase of an organizational change.     

A simple and inexpensive enteric-coated capsule for delivery of acid-labile macromolecules to the small intestine

Understanding the ecology of the gastrointestinal tract and the impact of the contents on the host mucosa is emerging as an important area for defining both wellness and susceptibility to disease. Targeted delivery of drugs to treat specific small intestinal disorders such as small bowel bacterial overgrowth and targeting molecules to interrogate or to deliver vaccines to the remote regions of the small intestine has proven difficult. There is an unmet need for methodologies to release probes/drugs to remote regions of the gastrointestinal tract in furthering our understanding of gut health and pathogenesis. In order to address this concern, we need to know how the regional delivery of a surrogate labeled test compound is handled and in turn, if delivered locally as a liquid or powder, the dynamics of its subsequent handling and metabolism. In the studies we report on in this paper, we chose ¹³C sodium acetate (¹³C-acetate), which is a stable isotope probe that once absorbed in the small intestine can be readily measured non-invasively by collection and analysis of ¹³CO₂ in the breath. This would provide information of gastric emptying rates and an indication of the site of release and absorptive capacity. In a series of in vitro and in vivo pig experiments, we assessed the enteric-protective properties of a commercially available polymer EUDRAGIT®L100-55 on gelatin capsules and also on DRcaps®. Test results demonstrated that DRcaps®coated with EUDRAGIT®L100-55 possessed enhanced enteric-protective properties, particularly in vivo. These studies add to the body of knowledge regarding gastric emptying in pigs and also begin the process of gathering specifications for the design of a simple and cost-effective enteric-coated capsule for delivery of acid-labile macromolecules to the small intestine.

Modeling the Interrelationships Among Pre-service Science Teachers’ Understanding and Acceptance of Evolution, Their Views on Nature of Science and Self-Efficacy Beliefs Regarding Teaching Evolution

This study proposed a path model of relationships among understanding and acceptance of evolution, views on nature of science, and self-efficacy beliefs regarding teaching evolution. A total of 415 pre-service science teachers completed a series of self-report instruments for the specified purpose. After the estimation of scale scores using unidimensional IRT models, path analysis suggested that sophisticated views on NOS were associated with higher levels of both understanding and acceptance of evolution, and the higher level of understanding of evolution was related to the higher level of acceptance of evolution. Besides, higher levels of both understanding and acceptance of the theory and na?ve views on NOS were found to be associated with stronger self-efficacy beliefs for teaching evolution effectively.     

Motivated Attention and Reward in Parenting

Parenting has a significant and lasting impact on child development. From birth, parents must sensitively and appropriately attend to their infant’s emotional expressions and vocalizations. Accumulating evidence indicates that these infant cues of emotion attract more attention than equivalent adult cues in parents as well as non-parents. We review this evidence and suggest that infant cues hold high incentive value and elicit motivated attention (i.e., enhanced processing of motivationally relevant stimuli), which in turn promotes approach motivation and thus caregiving responses. Further, we discuss data suggesting that infant cues are salient for non-parents, with increasing motivated attention to infant cues in the transition to parenthood. This increase may depend on interactions between the dopamine reward system and the neuropeptide oxytocin. Therefore, we also explore the human and non-human data that support this association and consider potential sources of variability in motivated attention in parents.     

Children's literacy environments and early word recognition subskills

First-grade children completed a battery of tasks that included standardized measures of word recognition and spelling, measures of phonological and orthographic processing skill, and a short indicator of exposure to print via home literacy experiences. Phonological and orthographic processing skill were separable components of variance in word recognition. Orthographic processing ability accounted for variance in word recognition ability even after the variance in three phonological processing measures had been partialed. Additionally, variance in orthographic processing ability not explained by phonological abilities was reliably linked to differences in print exposure. The print exposure measure was not, however, linked to the measures of phonological processing. This finding was unexpected but it is consistent with some previous research. The theoretical implications of this result are discussed.     

Building the College Library Collection to Support Curriculum Growth

Because the mission of smaller academic libraries serving fewer than 10,000 full-time enrolled students is mainly to serve the curriculum-based needs of students and faculty, collection management in these libraries needs to be directly related to changes in the curriculum of the parent institution. A look into applicable collection management literature, combined with one library's experience, offers insights about effective curriculum-based collection building in a smaller academic library setting. To achieve efficiency, collection managers must maintain up-to-date knowledge of changing instructional and research needs at their institutions, the needs new programs have for library materials, appropriate collection assessment tools, and the tasks involved in a focused expansion project. By optimizing consultations with faculty and evaluation procedures scaled to its needs, the library at North Georgia College & State University, a modestly sized academic institution, established a model for becoming an active participant in new course and program planning during the application stage, ensuring appropriate library support for new courses and programs of study.     

Experiences of a gifted and talented enrichment cluster for pupils aged five to seven

There has been an increased commitment to gifted and talented education in the UK in recent years, with a national strategy of grant-funded programmes. However, research into the effective-ness of gifted programmes is relatively limited. This paper, written by Anne Morgan of the Centre for Education and Inclusion Research at Sheffield Hallam University, investigates parents', teachers' and children's experiences and views of the impact of an enrichment programme for gifted and talented pupils aged five to seven. Methods included a survey of mainstream teachers (n = 15), interviews with parents (n = 17) and activities with pupils (between 16 and 24 children). Results showed that children and parents rated the cluster highly, particularly the varied teaching styles and interaction with other gifted children. There were few concerns regarding withdrawal of children from school in order to attend. All parents felt that their children had benefited from attending and around half said there had been an impact on their social and academic development. Similarly, around half of mainstream teachers said that attending the cluster had benefited children socially and academically.     

Cultural complexity, post-colonialism and educational change: Challenges for comparative educators

This study explores various elements in the struggle for a post-colonial refashioning of cultural identity through education. Drawing on experiences in Australia and the Caribbean, the author illustrates how educational systems undergoing decolonisation reflect socio-cultural tensions of race and power. The author discusses the complexities for comparative educators in engaging with suppressed knowledge, recognising the yearnings of the marginalised, challenging the conditions that lead to poverty, and refashioning education for social justice in an era when the achievement of justice seems increasingly difficult. She argues that comparative educators can benefit from using post-colonial thinking to understand cultural complexity and promote lifeaffirming practices in educational change.
