Students from divorced and blended families

Nielsen summarizes the research on the impact of parents' divorce and remarriage on elementary- and secondary-school students. By pointing out the shortcomings and discrepancies in the existing research, the author dispels several stereotypes often held by school personnel about students whose parents are divorced or remarried. Specifically, this article addresses the following questions: What factors affect grades and behavior after a divorce? How are children's attitudes toward divorce and family members assessed? In what ways can schools facilitate students' adjustment and academic performance after their parents divorce or remarry?     

Teachers’ reflections of professional change during a literacy-reform initiative

Policymakers recently have targeted teacher quality, and school systems have increased their attention to instructional reform through professional development. The purpose of this study was to examine teachers’ views about the change process and professional development that supports change. Semi-structured focus-group data were gathered from 41 primary-grades teachers (students ages 5–9) across five schools in a high-poverty urban district that participated in a 2-year literacy-reform initiative. Results indicated that teachers viewed the change process from two stances: as learners and as change agents. Three conditions supported their professional growth: professional development embedded in school and classroom contexts, professional development focused on limited and clearly defined learning goals, and on-demand access to time and resources. Changes that occurred did so in three phases: movement from curriculum-centered to student-centered practices, increased collaboration, and requests for policy changes via teacher autonomy and advocacy for students.     

High intensity and reduced volume training attenuates stress and recovery levels in elite swimmers

This study investigated the effect of increased high-intensity interval training (HIT) at the expense of total training volume on the stress and recovery levels of elite swimmers. Forty-one elite swimmers participated in the study and were randomly assigned to either a HIT or a control group (CON). Eleven swimmers did not complete the questionnaires. For 12 weeks both groups trained ~12 h per week. The amount of HIT was ~5 h vs. 1 h, and total distance was ~17 km vs. ~35 km per week for HIT and CON, respectively. HIT was performed as 6–10 × 10–30 s maximal effort interspersed by 2–4 min of rest. The Recovery Stress Questionnaire – Sport was used to measure the swimmers’ stress and recovery levels. After the 12 week intervention, the general stress level was 16.6% (2.6–30.7%; mean and 95% CI) lower and the general recovery level was 6.5% (0.7–12.4%) higher in HIT compared to the CON, after adjusting for baseline values. No significant effects could be observed in sports-specific stress or sports-specific recovery. The results indicate that increasing training intensity and reducing training volume for 12 weeks can reduce general stress and increase general recovery levels in competitive swimmers.     

The Selfie Study: Archetypes and Motivations in Modern Self-Photography

Photographic self-portraits have existed since the mid-19th century, but the emergence of digital photography and social media as tools that facilitate rapid visual communication have contributed to a surge of self-photographs, or selfies, and the practice has become a ubiquitous part of today's culture. This exploratory research employed a Q-method analysis to quantitatively and qualitatively identify what archetypal motivations exist among individuals who take and share selfies. The findings largely validated past scholarship on the uses and gratifications of photography, new media, and visual rhetoric individually, but also identified that the motivation to take and share selfies is a complex balance of preservation, communication, and entertainment for most individuals who engage in the practice.     

Biology Education Research: Lessons and Future Directions

This feature draws on a 2012 National Research Council report to highlight some of the insights that discipline-based education research in general—and biology education research in particular—have provided into the challenges of undergraduate science education. It identifies strategies for overcoming those challenges and future directions for biology education research.Biologists have long been concerned about the quality of undergraduate biology education. Indeed, some biology education journals, such as the American Biology Teacher, have been in existence since the 1930s. Early contributors to these journals addressed broad questions about science learning, such as whether collaborative or individual learning was more effective and the value of conceptualization over memorization. Over time, however, biology faculty members have begun to study increasingly sophisticated questions about teaching and learning in the discipline. These scholars, often called biology education researchers, are part of a growing field of inquiry called discipline-based education research (DBER).DBER investigates both fundamental and applied aspects of teaching and learning in a given discipline; our emphasis here is on several science disciplines and engineering. The distinguishing feature of DBER is deep disciplinary knowledge of what constitutes expertise and expert-like understanding in a discipline. This knowledge has the potential to guide research focused on the most important concepts in a discipline and offers a framework for interpreting findings about students’ learning and understanding in that discipline. While DBER investigates teaching and learning in a given discipline, it is informed by and complementary to general research on human learning and cognition and can build on findings from K–12 science education research.DBER is emerging as a field of inquiry from programs of research that have developed somewhat independently in various disciplines in the sciences and engineering. Although biology education research (BER) has emerged more recently than similar efforts in physics, chemistry, or engineering education research, it is making contributions to the understanding of how students learn and gain expertise in biology. These contributions, together with those that DBER has made in physics and astronomy, chemistry, engineering, and the geosciences, are the focus of a 2012 report by the National Research Council (NRC, 2012 ).1 For biologists who are interested in education research, the report is a useful reference, because it offers the first comprehensive synthesis of the emerging body of BER and highlights the ways in which BER findings are similar to those in other disciplines. In this essay, we draw on the NRC report to highlight some of the insights that DBER in general and BER in particular have provided into effective instructional practices and undergraduate learning, and to point to some directions for the future. The views in this essay are ours as editors of the report and do not represent the official views of the Committee on the Status, Contributions, and Future Directions of Discipline-Based Education Research; the NRC; or the National Science Foundation (NSF).     

Scientific Communication and the Nature of Science

Communication is an important part of scientific practice and, arguably, may be seen as constitutive to scientific knowledge. Yet, often scientific communication gets cursory treatment in science studies as well as in science education. In Nature of Science (NOS), for example, communication is rarely mentioned explicitly, even though, as will be argued in this paper, scientific communication could be treated as a central component of NOS. Like other forms of communication, scientific communication is socially and symbolically differentiated. Among other things, it encompasses technical language and grammar, lab communications, and peer reviews, all of which will be treated in this paper in an attempt to engage on an empirical and theoretical level with science as communication. Seeing science as a form of communicative action supplements the epistemological view of science that is standard to both NOS and the philosophy of science. Additions to the seven NOS aspects on Lederman’s (Handbook of research on science education. Lawrence Erlbaum, Mahwah, pp. 831–879, 2007) list are put forward as well as preliminary thoughts on the inclusion of scientific communication into NOS instruction.     

A model for the development of university curricula in nanoelectronics

Nanotechnology is having an increasing impact on university curricula in electrical engineering and in physics. Major influencers affecting developments in university programmes related to nanoelectronics are discussed and a model for university programme development is described. The model takes into account that nanotechnology affects not only physics but also electrical engineering and computer engineering because of the advent of new nanoelectronics devices. The model suggests that curriculum development tends to follow one of three major tracks: physics; electrical engineering; computer engineering. Examples of European curricula following this framework are identified and described. These examples may serve as sources of inspiration for future developments and the model presented may provide guidelines for a systematic selection of topics in the university programmes.
