The effectiveness of virtual and augmented reality in health sciences and medical anatomy

Although cadavers constitute the gold standard for teaching anatomy to medical and health science students, there are substantial financial, ethical, and supervisory constraints on their use. In addition, although anatomy remains one of the fundamental areas of medical education, universities have decreased the hours allocated to teaching gross anatomy in favor of applied clinical work. The release of virtual (VR) and augmented reality (AR) devices allows learning to occur through hands‐on immersive experiences. The aim of this research was to assess whether learning structural anatomy utilizing VR or AR is as effective as tablet‐based (TB) applications, and whether these modes allowed enhanced student learning, engagement and performance. Participants (n = 59) were randomly allocated to one of the three learning modes: VR, AR, or TB and completed a lesson on skull anatomy, after which they completed an anatomical knowledge assessment. Student perceptions of each learning mode and any adverse effects experienced were recorded. No significant differences were found between mean assessment scores in VR, AR, or TB. During the lessons however, VR participants were more likely to exhibit adverse effects such as headaches (25% in VR P < 0.05), dizziness (40% in VR, P < 0.001), or blurred vision (35% in VR, P < 0.01). Both VR and AR are as valuable for teaching anatomy as tablet devices, but also promote intrinsic benefits such as increased learner immersion and engagement. These outcomes show great promise for the effective use of virtual and augmented reality as means to supplement lesson content in anatomical education.

Improving Conceptual Understanding and Representation Skills Through Excel-Based Modeling

The National Research Council framework for science education and the Next Generation Science Standards have developed a need for additional research and development of curricula that is both technologically model-based and includes engineering practices. This is especially the case for biology education. This paper describes a quasi-experimental design study to test the effectiveness of a model-based curriculum focused on the concepts of natural selection and population ecology that makes use of Excel modeling tools (Modeling Instruction in Biology with Excel, MBI-E). The curriculum revolves around the bio-engineering practice of controlling an invasive species. The study takes place in the Midwest within ten high schools teaching a regular-level introductory biology class. A post-test was designed that targeted a number of common misconceptions in both concept areas as well as representational usage. The results of a post-test demonstrate that the MBI-E students significantly outperformed the traditional classes in both natural selection and population ecology concepts, thus overcoming a number of misconceptions. In addition, implementing students made use of more multiple representations as well as demonstrating greater fascination for science.     

Spanglish,Bilingualism, Culture and Identity in Latino Children’s Literature

This paper examines the ways in which Latino children’s literature portrays cultural models of bilingualism and identity affiliations based on language and cultural practices. We focus attention the messages in seven children’s books about practices of and attitudes toward Spanglish, standard Spanish, and individual and societal bilingualism. In addition, we analyze how characters construct their cross-cultural identit(ies), based their language use and engagement in local and transnational cultural themes. Using assertions based on cultural model analyses, we show how portrayals evident in these books inform and are informed by larger cultural models of being bilingual and belonging to Latino bilingual communities in the U.S.     

Content-Related Interactions in Self-initiated Study Groups

The central goal of the present exploratory study was to investigate the nature of the content-related interactions in study groups independently organized by college organic chemistry students. We were particularly interested in the identification of the different factors that affected the emergence of opportunities for students to co-construct understanding and engage in higher levels of cognitive processing. Our results are based on the analysis of in situ observations of 34 self-initiated study sessions involving over a 100 students in three academic semesters. The investigation revealed three major types of social regulation processes, teaching, tutoring, and co-construction in the observed study sessions. However, the extent to which students engaged in each of them varied widely from one session to another. This variability was mostly determined by the specific composition of the study groups and the nature of the study tasks in which they were engaged. Decisions about how to organize the study session, the relative content knowledge and conceptual understanding expressed by the participants, as well as the cognitive level of the problems that guided group work had a strong impact on the nature of student interactions. Nevertheless, group talk in the observed study groups was mostly focused on low-level cognitive processes. The results of our work provide insights on how to better support students' productive engagement in study groups.     

Do you want your child to have a certified teacher?

This study examines how the teaching staff composition with respect to certification affects student achievement in compulsory Swedish schools. We apply an instrumental variable to estimate the effect of the share of non-certified teachers on student achievement (measured by grade point average, GPA). We find statistically significant negative effects on the GPA. The effect is stronger for students with highly educated parents. A one percentage point increase in the share of non-certified teachers is expected to decrease student's GPA by, on average, 1.8 standard deviations per year. This is a substantial effect considering the large differences in the shares of non-certified teachers across schools and municipalities.     

Profiles of cognitive precursors to reading acquisition. Contributions to a developmental perspective of adult literacy

This article discusses conceptual and empirical elements concerning the development of cognitive processes that function as precursors of reading, and their association with the acquisition of reading skills in an adult population participating in literacy courses. It connects emergent literacy research with historical–cultural and bioecological concepts. Subsequently, it focuses on the problem of the development of profiles of cognitive reading precursors. A sample of 63 Chilean adults was studied through a growth/learning curves approach. The study replicated previous results indicating the existence of three major profiles of these cognitive precursors. Together, these precursors are associated with significantly different learning curves beyond the effect of each precursor considered separately. In addition, it established a negative association between initial phonological awareness and the rate of reading acquisition during the course. It has been claimed that an individual's participation in specific cultural activities throughout his/her life influences the development of the precursors of reading. Based on a complementary biographical study of a subsample of participants, preliminary evidence is presented that supports this link.     

Informal workplace learning: An exploration of age differences in learning competence

Informal learning is becoming a standard format in companies' training and development (T&D) activities. It requires a specific learning competence comprising cognitive, metacognitive, and motivational dimensions. In the present study, it was investigated whether learning-competence variables predict success in informal learning. Given the ageing of the workforce, we also explored age differences in learning competence in an online survey of 470 workers in three age groups (17–35, 36–50, and 51–65 years old) at a German mail-order company. Learning competence predicted success in informal learning independent of worker age, but was partially mediated by memory self-efficacy, which might induce second-order age effects under unfavourable T&D conditions.     

School placement and classroom participation among children with disabilities in primary school in Norway: a longitudinal study

The purpose of this paper is to address changes in school placement and classroom participation with respect to children with disabilities of primary school age in Norway, as well as examining the factors which explain variation in school placement and classroom participation. School placement refers to whether children with disabilities attend regular school, while classroom participation refers to time spent in regular classrooms at regular schools. The analysis is based on longitudinal data drawn from surveys undertaken in 2003 and 2006, of parents of children with disabilities. Present findings suggest there are no major changes in school placement during primary school years, which is contrary to earlier findings. However, the amount of time children with disability are absent from regular classes does increase significantly as the children become older. Size of municipality population, type of disability and degree of impairment are the main factors which have an impact on school placement. In addition to these, the amount of special education also has an impact on classroom participation. There are small changes in mechanisms that lead children out of both regular schools and classrooms, during their primary school years. However, some of the identified factors strengthen in importance as the children become older. The apparent policy change for older children, from special school placement to an “out of class” practice, is discussed. It could be seen as regular schools’ adaptation to the tension between the prevailing ideology of inclusion and schools’ maintenance of existing practice.
