Learning to play: A review and theoretical investigation of the developmental mechanisms and functions of cetacean play

Play is a behavioral phenomenon most commonly observed in the young of both solitary and social species. Documentation of play in cetaceans varies across species and settings. Cetacean play behavioral repertoires include a broad range of actions, such as the manipulation of diverse objects, blowing bubbles, chasing conspecifics, and swimming in spirals through the water. As is common in research on animal play, cetacean play has been grouped into categories by its form, including locomotor play, object play, and different variations of social play, such as affiliative games, play fighting, and socio-sexual play. Research has primarily focused on recording the topography of cetacean play and the demographics of the individuals engaging in play. However, these classifications are insufficient to address the possible developmental and societal functions of cetacean play behaviors, or the mechanisms with which play behaviors are spread between conspecifics and acquired by young members of cetacean populations. This article applies several developmental and social learning theories in order to organize current knowledge and guide future research.     

Oral traditions,changing rural landscapes,and science education

This forum response extends the argument made by Avery and Hains that oral traditions can be useful for including the cultures and contexts of rural areas within science instruction. To buttress the oral expressions presented in Avery and Hains, I compare oral expressions of a second rural area, 600 miles to the South, in Eastern North Carolina. I explore similarities and differences in expressions from the two areas and consider the changing rural context within Eastern North Carolina. I add a consideration of larger demographic shifts impacting many rural areas—particularly in the US South—and close with a discussion of implications for science education.     

Hemoglobin, growth, and attention of infants in southern Ethiopia

Male and female infants from rural Ethiopia were tested to investigate relations among hemoglobin (Hb), anthropometry, and attention. A longitudinal design was used to examine differences in attention performance from 6 (M = 24.9 weeks, n = 89) to 9 months of age (M = 40.6 weeks, n = 85), differences hypothesized to be related to changes in iron status and growth delays. Stunting (length‐for‐age z scores < ?2.0) and attention performance, t(30) = ?2.42, p = .022, worsened over time. Growth and Hb predicted attention at 9 months, R² = .15, p < .05, but not at 6. The study contributes to the knowledge base concerning the relations among Hb, early growth, and attention.     

Almost thinking counterfactually: children's understanding of close counterfactuals

Saying something "almost happened" indicates that one is considering a close counterfactual world. Previous evidence suggested that children start to consider these close counterfactuals at around 2 years of age (P. L. Harris, 1997), substantially earlier than they pass other tests of counterfactual thinking. However, this success appears to result from false positives. In Experiment 1 (N = 41), 3- and 4-year-olds could identify a character who almost completed an action when the comparison did not complete it. However, in Experiments 1 and 2 (N = 98), children performed poorly when the comparison character completed the action. In Experiment 3 (N = 28), 5- and 6-year-olds consistently passed the task, indicating that they made appropriate counterfactual interpretations of the "almost" statements. This understanding of close counterfactuals proved more difficult than standard counterfactuals.     

Career development influences of international students who pursue permanent immigration to Canada

This research focused on the career decision and planning needs of a unique group of migrants: international students who are completing their studies as temporary immigrants and who are embarking on the career journey of employment and permanent immigration. A semi-structured interview employing a Critical Incident Technique was used to assess the career influences of 19 undergraduate and graduate international students at a Canadian university. Data were analyzed using a constant comparison method and critical incident protocol. Students were motivated to remain in Canada due to enhanced job opportunities and high standard of living. Barriers to migration included the fear of not securing employment and cultural and linguistic barriers. International students would like to see campus and career services specified to the needs of international and graduate students to help them realize their goal of pursuing employment as the key to permanent immigration.

A Community College Instructor’s Reflective Journey Toward Developing Pedagogical Content Knowledge for Nature of Science in a Non-majors Undergraduate Biology Course

Research supports an explicit-reflective approach to teaching about nature of science (NOS), but little is reported on teachers’ journeys as they attempt to integrate NOS into everyday lessons. This participatory action research paper reports the challenges and successes encountered by an in-service teacher, Sarah, implementing NOS for the first time throughout four units of a community college biology course (genetics, molecular biology, evolution, and ecology). Through the action research cycles of planning, implementing, and reflecting, Sarah identified areas of challenge and success. This paper reports emergent themes that assisted her in successfully embedding NOS within the science content. Data include weekly lesson plans and pre/post reflective journaling before and after each lesson of this lecture/lab combination class that met twice a week. This course was taught back to back semesters, and this study is based on the results of a year-long process. Developing pedagogical content knowledge (PCK) for NOS involves coming to understand the overlaps and connections between NOS, other science subject matter, pedagogical strategies, and student learning. Sarah found that through action research she was able to grow and assimilate her understanding of NOS within the biology content she was teaching. A shift in orientation toward teaching products of science to teaching science processes was a necessary shift for NOS pedagogical success. This process enabled Sarah’s development of PCK for NOS. As a practical example of putting research-based instructional recommendations into practice, this study may be very useful for other teachers who are learning to teach NOS.     

A Behind‐the‐Scenes Guide to School‐Based Research

Schools are an important context for both basic and applied scientific research. Unlike the laboratory, however, the physical and social conditions of schools are not under the exclusive control of scientists. In this article, we liken collecting data in schools to putting on a theatrical production. We begin by describing the large cast of characters whose collaborative efforts make school‐based research possible. Next, we address the critics, including the university Institutional Review Board (IRB) and school administrators, whose feedback often improves the final study design. We then turn our attention to set building, stage directions, and rehearsals—key steps in the iterative process of refining study procedures. We end with a discussion of the day of data collection itself and activities that take place after the curtain drops. Throughout, we make recommendations based on our recent experience collecting data at several high schools.     

Access to Research: the experience of implementing a pilot in public libraries

The Access to Research project is a collaboration between scholarly publishers and librarians to provide free licensed access to research journals via terminals in public libraries. The project is an element of the ‘balanced package’ proposed by the Finch Working Group on how to expand access to published research in the UK, which reported its recommendations to the UK government in June 2012. We describe the setting up of the project and the findings from a three‐month technical pilot prior to the launch of a two‐year national pilot in February 2014. The project has already attracted support from the major scholarly publishers, with about 8,400 journal titles now available. The access platform has been shown to be usable by public librarians and library patrons. We are now addressing the challenge of understanding how the public will make use of the system and exploring how best to provide training and education for librarians and users.
