Enhancing Anatomical Instruction: Impact of a Virtual Canine Anatomy Program on Student Outcomes

Innovative reforms in medical education will require instructional tools to support these changes and to give students more flexibility in where and how they learn. At Colorado State University, the software program Virtual Canine Anatomy (VCA) was developed to assist student learning both inside and outside the anatomical laboratory. The program includes interactive anatomical photographs of dissected canine cadavers, dissection instructions with accompanying videos and diagrams, radiographs, and three-dimensional models. There is a need to evaluate the effectiveness of instructional tools like VCA so that decisions on pedagogical delivery can be evidence-based. To measure the impact of VCA on student outcomes in a dissection laboratory, this study compared student attitudes, quiz scores, dissection quality and accuracy, and instructor reliance between students with and without access to VCA. Students with VCA needed less time with teaching assistants (P < 0.01), asked teaching assistants fewer questions (P = 0.04), felt that the dissection was easier (P = 0.02), and were in stronger agreement that they had access to adequate resources (P = 0.02). No differences were found in the dissection quality or accuracy, quiz scores, or attitudes regarding overall enjoyment of the activity between the two groups. This study shows that VCA increases student independence and can be used to enhance anatomical instruction.     

How do students’ accounts of sociology change over the course of their undergraduate degrees?

In this article we examine how students’ accounts of the discipline of sociology change over the course of their undergraduate degrees. Based on a phenomenographic analysis of 86 interviews with 32 sociology and criminology students over the course of their undergraduate degrees, we constituted five different ways of accounting for sociology. These ranged from describing sociology as a form of personal development focused on developing the students’ opinion to describing sociology as a partial way of studying the relations between people and society. The majority of students expressed more inclusive accounts of sociology over the course of their degrees. However, some students’ accounts suggested they had become disengaged with sociology. We argue that the differences in the ways that students were disengaged were not captured by our phenomenographic categories. In conclusion, we argue that our analysis illustrates the crucial role that students’ relations to knowledge play in understanding the transformative nature of higher education.     

The promise of ritual: a lens for understanding persistent practices in mathematics classrooms

In this article, I propose ritual as an analytic lens for understanding the persistence of practices in contemporary mathematics classrooms. By foregrounding the cultural nature of the teaching and learning of mathematics in schools, ritual analysis can provide insight about the causes and effects of practices that persist through rounds of “reform.” I begin by considering the legacy of the notion of culture in mathematics education research. I then provide examples of ritual analysis in education research and in mathematics education research. I draw on the scholarship of Quantz (2011) as I articulate a working definition of ritual for use in mathematics education research, considering how this definition may help raise and answer distinct questions apart from more familiar constructs. I list some well-known problems and dilemmas in mathematics education that may be promising domains for a ritual analysis, and I conclude by positioning ritual alongside other constructs and methods that are in use in mathematics education research today.     

Drop-outs from Swiss Universities: an empirical analysis of data on all students between 1975 and 2008

This study presents in-depth empirical analyses of drop-outs from all Swiss universities for the entire student population between 1975 and 2008. The results show that most identifiable factors associated with a greater or lesser probability of dropping out are identical to those found in a recent Systematic Review (Larsen et al., 2013). The main findings are that: first, since the 1970s, there has been a marked trend towards falling drop-out rates which is largely due to female students who, today, have lower drop-out rates than their male counterparts; secondly, not only are there different drop-out rates for specific subjects of study, but there are also differences in baccalaureate profiles, which indicates that the skills acquired prior to entering university have a great impact on successful study; thirdly, students who change their first subject choice are at great risk of dropping out. No firm conclusions can yet be drawn about the Bologna reform but, based on the subjects which changed to the Bachelor/Master system between 2001 and 2003, no reduction in drop-out rates can be found as a result of the reform.     

Authentically assessing graduate teaching: outside and beyond neo-liberal constructs

In this paper, we challenge the current focus on ‘best practice’, graduate teacher tests, and student test scores as the panacea for ensuring teaching quality and argue for ways of thinking about evidence of quality beginning teaching outside and beyond the current neoliberal accountability discourses circulating in Australia and other countries. We suggest that teacher educators need to reinsert themselves as key players in the debates around quality beginning teaching, rather than being viewed as a source of the problem. To enable teacher educators to assume accountability for quality beginning teachers, we propose the framework of a capstone teacher performance assessment—a structured portfolio called the Authentic Teacher Assessment (ATA)—and examine examples of these assessments through the lens of critical discourse analysis. As a measure of ‘readiness to teach’, the ATA is compared with supervising teachers’ assessments of preservice teachers. We argue that structured portfolios that include artefacts derived from preservice teachers’ practice in classrooms along with graduate teacher self assessments provide a stronger accountability measure of effective beginning teaching and demonstrably address the current anxiety regarding ‘evidence’. We suggest that such an approach should be reliable enough to be ‘read’ by external assessors (and moderated across other teacher education institutions). Rigorous research on a national basis is called for in order to develop and implement a structured portfolio as rich evidence of graduates’ quality and readiness to teach.     

Engaging Faculty for Innovative STEM Bridge Programs

Bridge programs, in which underprepared students gain the academic and technical skills necessary for college level courses and entry-level employment, are a promising initiative for expanding access to, and success in, community college education. For career pathways related to science, technology, engineering, or mathematics (STEM), bridge programs are critical for enlarging the pool of students who are exposed to, and can aspire to, STEM preparation. This study, conducted with support from the National Science Foundation Advanced Technological Education program, followed four community colleges for a year to understand local factors that facilitated or impeded implementation of a bridge program in which basic skills were contextualized in biotechnology. The findings are that implementation of a contextualized curriculum requires substantial faculty learning. Implementation of these bridge programs was facilitated by instructional leadership by both administration and faculty. Administration assisted in creating the conditions that supported learning by coordinating faculty schedules and funding faculty time for initial and ongoing program development. Faculty benefitted by the support of experienced team members who could guide interdisciplinary learning. Implementation was facilitated when team members met frequently and when faculty worked collaboratively to implement the curriculum. Recommendations include planning for faculty development, both for faculty collaboration and contextualizing curriculum.     

They Said So on the News: Parsing Media Reports About Birth

In this column, the authors reprise recent selections from the Lamaze International research blog, Science & Sensibility. Each selection discusses shortcomings in the news media coverage of childbirth issues. The authors demonstrate how to identify misleading claims in the media and highlight how childbirth educators can apply a common-sense approach and careful fact checking to help women understand the whole story.     

The effects of computer-assisted instruction on number combination skill in at-risk first graders

The purpose of this pilot study was to assess the potential for computer-assisted instruction (CAI) to enhance number combination skill among children with concurrent risk for math disability and reading disability. A secondary purpose was to examine the effects of CAI on spelling. At-risk students were assigned randomly to math or spelling CAI, which they received in 50 sessions over 18 weeks. Acquisition and transfer effects were assessed. The results indicated that math CAI was effective in promoting addition but not subtraction number combination skill and that transfer to arithmetic story problems did not occur. Spelling CAI effects were reliable on acquisition and transfer spelling measures, with small to moderate effect sizes on transfer to reading measures. These results provide the basis for additional work with larger samples.
