Optimization of configurations of field problem grids using network models

Optimization of grid configurations decreases the discretization error in the numerical solution of field problems. In this paper, the theoretical and algorithmic aspects of optimizing configurations of grids used in equilibrium, potential-type field problems is presented. The criterion for establishing the optimum grid and the steps required to move to the optimum grid are given. Sensitivity network modelling is invoked to systematically form matrices required in the algorithm. One-dimensional examples are presented to illustrate the validity of the approach.     

Birth stories: a way of knowing in childbirth education

Birth stories have a lasting impact on expectant mothers. The purpose of this paper is to recognize the influence of birth stories as a key component of informal communication of knowledge about childbirth for expectant mothers. The review of literature and research is related to childbirth education, anthropological thinking, and applied learning theory with foundational concepts from Vygotsky, Bruner, and Bandura. Implications for childbirth educators are included.     

Name writing but not environmental print recognition is related to letter-sound knowledge and phonological awareness in pre-readers

This paper reports a study exploring the associations between measures of two levels of phonological representation: recognition (epi-linguistic) and production (meta-linguistic) tasks, and very early reading and writing skills. Thirty-eight pre-reading Ottawa-area children, aged 4–5 years, named environmental print (EP), wrote their own name, identified correct names and EP words amongst foils and detected foil letters within EP and names. Results showed that phonological awareness and letter-sound knowledge were not related to EP recognition. Name writing accuracy and name identification were related to both levels of phonological awareness. Furthermore, name writing showed a unique association with phonological awareness even after letter-sound knowledge was controlled statistically. Pre-readers may first use meta-linguistic phonological awareness in their name writing and identification prior to learning to read.     

Software to Promote Young Children’s Growth in Literacy: A Comparison of Online and Offline Formats

The primary goal of this research was to extend our understanding of the strengths and weaknesses inherent in online and offline early literacy software programs designed for young learners. A taxonomy of reading skills was used to contrast online software with offline closed system (compact disc) based programs with respect to number of skills taught, quality of instruction and scaffolding during instruction. Overall, online programs were more comprehensive and provided instruction for more skills than offline software at either the Kindergarten or Grade 1 level. However, offline programs demonstrated some developmentally appropriate selectivity in skills trained. Quality of instruction was variable within and across all programs. Scaffolding of instruction was also variable and surprisingly few programs, either online or offline, provided automatic movement across levels of difficulty. These outcomes have important implications for the selection of instructional materials by parents and educators involved in early literacy instruction and also for future software design.     

Lesbian,gay, bisexual,and transgender college students with disabilities: A look at multiple cultural minorities

College students with disabilities who are lesbian, gay, bisexual, or transgender (LGBT) represent diverse cultural minorities with multiple service needs involving disabilities, identities, and adjustment strategies. These students are usually accommodated in the college environment because of their disability while simultaneously marginalized based on their sexual orientation. This article discusses LGBT college students with disabilities as multiple cultural minorities with a focus on educational environments, institutional issues, and strategies for university personnel. © 2002 Wiley Periodicals, Inc.     

How and why the CAUT became involved in collective bargaining

Despite a persistent belief to the contrary, most Canadian universities prior to the 1960s did not operate collegially. They were run autocratically. Collective bargaining arose as a means of ensuring true collegiality through negotiations between equals, legally entrenching due process and academic freedom, and providing a clearer and stronger mechanism for dealing with salaries and benefits. This was a revolution from below in the governance of universities. Although the sixties are widely regarded as the age of student revolt, in Canada it was the faculty, not the students, who secured a dramatic change in the power structure of the university through collective bargaining.     

Who says we are not attracting the best and brightest? Teacher selection and the aspirations of Australian school students

Internationally, the quality of teachers is a growing focus of educational reform, with new policies attempting to ensure that only the ‘best and brightest’ are selected for the teaching profession. This article tests the assumption underpinning these developments that prospective teachers lack the desired academic and personal qualities. Drawing on data on the career aspirations of 6492 Australian school students in Years 3–12, we investigated who, among these students, expressed interest in teaching and their reasons for doing so. Using logistic regression, we found that interest in teaching was widespread and prior academic achievement was not a significant predictor. Thematic analysis of reasons expressed for interest in teaching indicated that working with children and/or in specific subject areas, altruism, and perceptions of personal suitability for the job dominated student responses. These data provide a counter-narrative to the primacy, in policies for teacher recruitment and selection, of needing to attract ‘better’ students. We argue that policies for improving teacher quality should also capitalise on the widespread interest in teaching among school students. Without such a discursive broadening, we caution that current attempts to attract the ‘best and brightest’ risk undermining the very goals espoused.     

Professional experience: learning from the past to build the future

The title of the 2014 Australian Teacher Education Association (ATEA) conference was Teacher Education, An Audit: Building a platform for future engagement. One of the conference themes was Professional Experience: What works? Why? I seized upon this theme and the title of the conference as it afforded me an opportunity to do an audit of my research in professional experience over the last 25 years. This article presents this evidence base and the messages I have taken from this evidence. I have done this in the hope that, by collating some of the insights gained from the past and the present, it will help to “build a platform for future engagement” in professional experience. In preparing this article I was asked by the Editors to reflect also on how I developed my distinctive line of inquiry and expertise in relation to the practicum across an extended period. These reflections are included. I hope they will support university-based teacher educators in enhancing their satisfaction and achievements from working in this stimulating and provocative field of study.     

The effects of rime‐ and phoneme‐based teaching delivered by Learning Support Assistants

This paper evaluates three word‐level teaching programmes delivered by trained Learning Support Assistants (LSAs) for Year 1 children ‘at risk’ of reading difficulties. Rime‐based, phoneme‐based, and ‘mixed’ (rime and phoneme‐based) interventions were contrasted with controls receiving only the National Literacy Strategy. Phonological onset‐rime and phoneme manipulation, spelling, and word and non‐word reading were measured before and after the nine‐week intervention. High rime neighbourhood (HRn) non‐words (e.g. ‘dat’– with many real word rime neighbours) and low rime neighbourhood (LRn) non‐words (e.g. ‘tav’ with few real word neighbours) were used to evaluate onset‐rime‐ or grapheme‐phoneme‐based decoding strategies. Results showed greater phonological onset‐rime skills, letter‐sound knowledge and non‐word reading skills in all LSA‐taught intervention groups. There was no difference between the HRn and LRn non‐words. The only reliable difference between the intervention groups was an advantage in phoneme blending for the rime‐taught group. It was concluded that LSAs can enhance literacy development for 6‐year‐old poor readers. There appears to be no simple association between rime‐ or phoneme‐based teaching intervention and changes in the size of unit used by children following interventions.
