Twenty questions about student errors

Errors in science learning (errors in expression of organized, purposeful thought within the domain of science) provide a window through which glimpses of mental functioning can be obtained. Errors are valuable and normal occurrences in the process of learning science. A student can use his/her errors to develop a deeper understanding of a concept as long as the error can be recognized and appropriate, informative feedback can be obtained. A safe, non-threatening, and nonpunitive environment which encourages dialogue helps students to express their conceptions and to risk making errors. Pedagogical methods that systematically address common student errors produce significant gains in student learning. Just as the nature-nurture interaction is integral to the development of living things, so the individual-environment interaction is basic to thought processes. At a minimum, four systems interact: (1) the individual problem solver (who has a worldview, relatively stable cognitive characteristics, relatively malleable mental states and conditions, and aims or intentions), (2) task to be performed (including relative importance and nature of the task), (3) knowledge domain in which task is contained, and (4) the environment (including orienting conditions and the social and physical context). Several basic assumptions underlie research on errors and alternative conceptions. Among these are: Knowledge and thought involve active, constructive processes; there are many ways to acquire, organize, store, retrieve, and think about a given concept or event; and understanding is achieved by successive approximations. Application of these ideas will require a fundamental change in how science is taught.     

Openness and reciprocity: Indigenous community requirements for hosting university students*

ABSTRACT

Although there is a substantial literature critical of the colonising discourses of higher education in both teaching and learning and research, there has been relatively little commentary about work integrated learning (WIL) from an Indigenous perspective. Currently, the higher education discourse of WIL is dominated by a teaching and learning perspective, which focuses almost entirely on the benefits to the student and/or the educational institution. This leaves the Indigenous community experience invisible and continues to reinforce a neo-colonial relationship between higher education providers and Indigenous people. This article reports the findings of a study undertaken in partnership with the Aboriginal community of Cherbourg in Queensland, Australia, which sought to understand the community experience of students undertaking WIL within Cherbourg. Twenty yarns, undertaken by a research assistant employed from the community, provided the basis for identifying key meanings and requirements of the community in their hosting of higher education students. The recent experience of students by the community was found to be positive with reciprocity, openness and practical benefit over time being central concerns. The study concludes that WIL with Indigenous agencies and communities requires decolonising, temporal and relational frames to be employed in the process of negotiating the purpose and processes of higher education student engagement.     

Contemporary induction to teaching in Australian universities

Australia has 42 universities. In 2015/16, 30 of 40 universities reviewed provided one or more days of teaching induction for their staff, while 10 did not. Twenty-six of the 30 teaching induction program directors were surveyed and 24 of those were interviewed to provide a snapshot of professional development for new teaching staff in Australian universities. The key findings of that research showed that almost two thirds of universities did not pay sessional staff to attend a teaching induction program; just over half the programs included peer observation of teaching; only one in five programs offered mentoring opportunities; three quarters of programs included assessment; and approximately a third of programs provided credit towards an award course. We conclude that all universities need to provide new teaching staff with a longer teaching induction program, which will support them to develop student-centred, scholarly behaviours and attitudes.     

Early Predictors of Attachment in Infants with Cleft Lip and/or Palate

Previous studies have found that children with cleft lip and palate (CLP) and isolated cleft palate (CP) have elevated risk for a variety of psychosocial problems, but the origins of such problems are unclear, We excted that early medical and other stressors during infancy—including feeding problems and facial disfigurement—would have adverse effects on the infant, his or her caregivers, and the family environment, leading to a higher than expected rate of insecure attachments among infants with clefts. Twelve-month attachment classifications of CLP, CP, and comparision group infants were examined. No significant group differences in attachment status were found. When 3-month infant, maternal, and social/family characteristics were examined as potential predictors of insecure attachment, predictors interacted with diagnostic status. For the cleft group, infant and maternal characteristics, but not family characteristics, significantly predicted insecure attachment. For the comparison group, maternal and family characteristics, but not factors associated with the infant, were predictive. Infants with clefts despite their special needs and caregiving requirements, seem not to have elevated risk for insecure attachments at the end of their first year. Contrary to social-psychological formulations, the facial appearance of infants with CLP had no adverse effect on the quality of their maternal attachment.     

Gender Gaps in North American Research Productivity: Examining Faculty Publication Rates in Mexico,Canada, and the U.S.

The present study addresses gender gaps in North American research productivity, which may be influenced by personal and family variables, as well as professional and work-related variables. The study was conducted as part of the Changing Academic Profession (CAP) International Survey, conducted in 2007–08. Using articles as indicator of research productivity, we analyzed the gender gap in publication rates among full-time higher education faculty in our combined sample (Canada, Mexico, and the United States). This analysis has implications for higher education policy. In terms of research productivity, the relative productivity rates of male and female academics have been a policy priority for many years to increase the cumulative rates of research activity. We found that the variables related to research intensity varied by country, providing a more nuanced understanding of the gender gap between male and female faculty.     

Pejorative phrases or innocent idioms? Exploring terms used by tomorrow’s doctors in relation to older people

ABSTRACT

Older people are the “core business” for 21st century hospitals. Of concern, therefore, is negative stereotyping of older people by medical students. Through a bespoke teaching session for final-year medical students, we aimed to deconstruct the phraseology they employed in relation to older people and to drive attitudinal change among students. This study also aimed to discern whether there was a detectable difference in attitudes toward older people after the session. Forty-seven medical students participated. Students recorded in a “word-cloud” terms they associated with older people in hospital before and after the session. The University of California Los Angeles Geriatrics Attitude Scale (UCLA-GAS) was administered for pre-session. The intervention students, along with a control group, completed this instrument at the end of their placement. Content analysis of word cloud data was performed—an iterative, transparent, structured approach to analysis, along with external critique of findings and collaborative triangulation ensured rigor of analysis. Qualitative analysis demonstrated the use of pejorative and sometimes nihilistic terms. There were evidence of growing appreciation of the inherent complexity of caring for older people and increasing awareness of how healthcare systems can be challenging for older people. Quantitative analysis revealed that there is no statistical difference neither between the UCLA-GAS pre- and post-teaching nor the intervention and control groups. In conclusion, a bespoke educational intervention, designed to promote student reflection on their views toward older people in hospital, can be a catalyst to challenging superficial and stereotypical views.     

Partially plastic thick-walled tubes

A theory is presented for the partial plastic yielding of thick-walled cylindrical tubes acted upon by any combination of internal pressure, external pressure and end load when the material follows an arbitrary stress-strain law. The solution combines (a) the distortion energy theory of plastic flow and (b) the effects of elastic compressibility of the plastic material.Numerical values for stresses and strains are given for certain special cases of internal pressure in thick-walled open-ended tubes for an idealized stress-strain law, and the results are compared with earlier approximate theories.
