The Effectiveness of an Augmented Reality Head-Mounted Display in Learning Skull Anatomy at a Community College

Despite an increase in the use of technology in undergraduate anatomy education, and the rising popularity of online anatomy courses at community colleges in the United States, there have been no reports on the efficacy of augmented reality on anatomy education in this population. The purpose of this study was to test the hypothesis that augmented reality is an effective and engaging tool for learning anatomy in community college students. Participants recruited from Cuyahoga Community College (Cleveland, OH) studied skull anatomy using either traditional tools (i.e., textbook and plastic skull model) or an augmented reality head-mounted display with an interactive virtual skull application. Comparison of knowledge before and following the study period revealed that augmented reality was an effective tool for learning skull anatomy: pre-quiz = 32.7% (± 25.2); mean (± SD), post-quiz = 61.8% (± 19.5); n = 15; t₍₂₈₎ = 3.53; P = 0.001. The traditional tools were equally effective: pre-quiz = 44.9 % (± 18.6), post-quiz = 67.9 % (± 17.3); n = 17; t₍₃₂₎ = 3.73; P = 0.0007. Students rated the augmented reality device as 9.6 (± 1.0); mean (± SD) when asked if it fit the statement “fun to use” on a semantic differential scale from 1 (poor) to 10 (excellent). In conclusion, this study found that augmented reality is an effective and engaging tool for the instruction of skull anatomy at a community college.     

Open access megajournals: The publisher perspective (Part 1: Motivations)

This paper is the first of two Learned Publishing articles in which we report the results of a series of interviews with senior publishers and editors exploring open access megajournals (OAMJs). Megajournals (of which PLoS One is the best known example) represent a relatively new approach to scholarly communication and can be characterized as large, broad‐scope, open access journals that take an innovative approach to peer review, basing acceptance decisions solely on the technical or scientific soundness of the article. This model is often said to support the broader goals of the open science movement. Based on in‐depth interviews with 31 publishers and editors representing 16 different organizations (10 of which publish a megajournal), this paper reports how the term ‘megajournal’ is understood and publishers’ rationale and motivations for launching (or not launching) an OAMJ. We find that while there is general agreement on the common characteristics of megajournals, there is not yet a consensus on their relative importance. We also find seven motivating factors that were said to drive the launch of an OAMJ and link each of these factors to potential societal and business benefits. These results suggest that the often polarized debate surrounding OAMJs is a consequence of the extent to which observers perceive publishers to be motivated by these societal or business benefits.

Sex differences in the etiology of aggressive and nonaggressive antisocial behavior: results from two twin studies

Recent theory and results from twin and adoption studies of children and adolescents suggest greater genetic influence on aggressive as compared to nonaggressive antisocial behavior. In addition, quantitative or qualitative differences in the etiology of these behaviors in males and females have been indicated in the literature. The Child Behavior Checklist was completed by the parents of 1022 Swedish twin pairs aged 7-9 years and of 501 British twin pairs aged 8-16 years. Genetic factors influenced aggressive antisocial behavior to a far greater extent than nonaggressive antisocial behavior, which was also significantly influenced by the shared environment. There was a significant sex difference in the etiology of nonaggressive antisocial behavior. Bivariate analyses supported the conclusion that the etiologies of aggressive and nonaggressive antisocial behavior differ for males and females.     

Aesthetic experiences in the Cerrado (Brazilian savanna): contributions to environmental education practice and research

In this paper, we reflect on a study in Brazil’s Cerrado that attempts to address a lack of attention to an aesthetic dimension in environmental education practice and research. We start by tracing this lack to the overvaluing of the cognitive sphere in the educational process, noting its echo in the low aesthetic value attributed to the Cerrado biome. Then, through reflecting on an empirical, interview based study of sensations, perceptions and feelings evoked by aesthetic experiences in the Cerrado, we draw on insights from a hermeneutic phenomenological approach to identify key themes for environmental education research and practice in this regard. These include: recognising the singularity of experience; attending to the qualities of experience; acknowledging the value/s of ‘lighter’ and ‘darker’ experiences; and deepening emotions and verbal communication. In our final considerations, we discuss the limitations of the study, alongside new directions in studies of perception, experience, aesthetics and pedagogy that may also advance attention to an aesthetic dimension in environmental education practice and research.     

Sustaining education for sustainability in turbulent times

A study of two schools in northern Australia demonstrated the impact on Education for Sustainability (EfS) initiatives of a disruptive policy environment set in motion by neoliberal reforms focused on standards, accountability, and international competitiveness. In one of the schools, a culture characterized by trust and an emphasis on cultivating teacher and student strengths and interests contributed to the resilience of these initiatives in the face of outside pressures. In the other, administrators preoccupied with the need to implement state mandates with fidelity failed to nurture and develop a collection of remarkable EfS projects and activities.     

Sustainable development as a driver for educational innovation in engineering school: the case of UniLaSalle

ABSTRACT

The potential relationships between innovation and sustainability processes, in engineering education, is neither obvious nor simple, especially when innovation, generally speaking, is promoted regardless of sustainability. We used UniLaSalle (In January 2016, the ‘Institut Polytechnique LaSalle Beauvais’, a French engineering school, merged with another higher education engineering school (ESITPA, Rouen). Both campuses (Beauvais and Rouen) have a common name: UniLaSalle (www.unilasalle.fr). As the interview began during 2015, this article only describes the situation of the Beauvais campus.) as a ‘living Lab’ to identify and analyse the reasons for the integration of innovation and Sustainable Development (SD) in training programmes. The aim is to explore, in a perception and reflective approach, how SD can be understood as a driver for specific innovation attitudes in higher education engineering school. This paper adopts an empirical approach based on a qualitative study, using NVivo 9 software to analyse non-numerical data. Our research suggests that SD can be a structural driver for innovation if it is integrated in a transdisciplinarity approach and not just as a discipline per se.     

Identifying sex differences in reading disability

The issue of sex differences in reading disability has been of recent interest in relation to sex ratios in families with reading disabled children and to possible sex biases in referred populations. Data from a study of 570 twins are used to develop alternative definitions of reading disability that vary in the manner to which sex effects are taken into account. These definitions include discrepancies between reading quotients and IQ, the use of the regression of reading onto IQ and chronological age/reading age differences. In each case the reading and spelling disability was defined either separately for the sexes or based upon the data for the sexes combined and with and without an IQ>90 exclusion criterion. The consequences of using the alternative definitions for prevalence, sex ratio and heritability are examined. The results demonstrate that the characteristics of reading disabled children vary with the way disability is defined. The excess of males seems to be a robust finding. Definitions that take into account differences in mean score for males and females reduce but do not eradicate the sex ratio. From the genetic analysis, there is no support for the suggestion that the genetic effect on reading is greater for females than males. It is concluded that the use of regression based procedures for identifying reading disability is desirable but that at present there is insufficient evidence to justify the adoption of separate regression procedures for the two sexes.     

Genetic etiology of spelling deficits in the Colorado and London twin studies of reading disability

The basic multiple regression model for the analysis of selected twin data (DeFries and Fulker 1985, 1988) was fitted to spelling data from 100 pairs of MZ twins and 71 pairs of same-sex DZ twins tested in the Colorado Reading Project (DeFries, Olson, Pennington and Smith 1991), and to data from 12 pairs of MZ twins and 15 pairs of same-sex DZ twins tested in the London twin study of reading disability (Stevenson, Graham, Fredman and McLoughlin 1984, 1987). Estimates of h _g ² obtained from analyses of these data suggest that about 60% of the deficit of probands is due to heritable influences in both samples. When a regression model was fitted separately to data from males and females in the combined Colorado and London samples, resulting estimates of h _g ² were 0.66±0.18 and 0.56±0.19, respectively, a nonsignificant difference. Collaborative analyses of data from additional twin studies of reading disability would facilitate more rigorous tests of hypotheses of differential genetic etiology as a function of group membership.
