Contextualizing Nature of Science Instruction in Socioscientific Issues

The purpose of this study was to investigate the effects of two learning contexts for explicit-reflective nature of science (NOS) instruction, socioscientific issues (SSI) driven and content driven, on student NOS conceptions. Four classes of 11th and 12th grade anatomy and physiology students participated. Two classes experienced a curricular sequence organized around SSI (the SSI group), and two classes experienced a content-based sequence (the Content group). An open-ended NOS questionnaire was administered to both groups at the beginning and end of the school year and analyzed to generate student profiles. Quantitative analyses were performed to compare pre-instruction NOS conceptions between groups as well as pre to post changes within groups and between groups. Both SSI and Content groups showed significant gains in most NOS themes, but between-group gains were not significantly different. Qualitative analysis of post-instruction responses, however, revealed that students in the SSI group tended to use examples to describe their views of the social/cultural NOS. The findings support SSI contexts as effective for promoting gains in students’ NOS understanding and suggest that these contexts facilitate nuanced conceptions that should be further explored.     

Indigenous Political Difference,Colonial Perspectives and the Challenge of Diplomatic Relations: Toward a Decolonial Diplomacy in Multicultural Educational Theory

This article considers how diplomacy can be refined and amplified within the field of multicultural education. Focusing on Native American peoples in particular, I argue that the multiculturalist emphasis on cultural diplomacy overlooks the political difference of First Nations peoples. In contrast to a multiculturalist cultural diplomacy, the article develops diplomacy according to a decolonial framework that seeks to dismantle colonial perspectives of Native American political difference. Drawing upon theorists and historians of diplomacy, as well as Indigenous and decolonial writers, the article seeks to provide the terms through which teacher identifications as decolonial diplomats can be fostered toward Native Americans.     

DETERMINING THE SUCCESS OF GRANDPARENT EDUCATION

The purpose of this study was to evaluate the outcomes of a course for grandparents. A sample of 87 consanguineous subjects included 29 grandparents, 29 grandchildren, and 29 of the grandchildren's parents. Twelve class sessions explored how the experiences of growing up and raising children differ from the recent past and attempted to identify corresponding changes required for the older relatives. Each generation was administered the Grandparent Strengths and Needs Inventory before and after grandparents attended the course. The participants reported perceptions regarding six dimensions of grandparent attitudes and behaviors. Changes in the performance of grandparents were compared using t‐tests. According to the grandparents, the course resulted in increased satisfaction (p < .05), greater success (p < .05) and more effective teaching (p < .05) in family relationships. They reported making gains for 58 out of 60 items. Parents and grandchildren corroborated most of these gains by higher posttest scores. MANOVA identified significant differences in generational perceptions of grandparent potentials (p < .05) and concerns (p < .01). The findings confirm that family development goals can be supported by making education for grandparents available and encouraging them to remain influential in their families through continued learning.     

Students’ Participation in an Interdisciplinary, Socioscientific Issues Based Undergraduate Human Biology Major and Their Understanding of Scientific Inquiry

The purpose of this study was to examine whether Socioscientific Issues (SSI) based learning environments affect university students’ epistemological understanding of scientific inquiry differently from traditional science educational contexts. We identify and compare conceptions of scientific inquiry of students participating in an interdisciplinary, SSI-focused undergraduate human biology major (SSI) and those participating in a traditional biology major (BIO). Forty-five SSI students and 50 BIO students completed an open-ended questionnaire examining their understanding of scientific inquiry. Eight general themes including approximately 60 subthemes emerged from questionnaire responses, and the numbers of students including each subtheme in their responses were statistically compared between groups. A subset of students participated in interviews, which were used to validate and triangulate questionnaire data and probe students’ understanding of scientific inquiry in relation to their majors. We found that both groups provided very similar responses, differing significantly in only five subthemes. Results indicated that both groups held generally adequate understandings of inquiry, but also a number of misconceptions. Small differences between groups supported by both questionnaires and interviews suggest that the SSI context contributed to nuanced understandings, such as a more interdisciplinary and problem-centered conception of scientific inquiry. Implications for teaching and research are discussed.     

Teachers’ Concerns About Biotechnology Education

The impacts of biotechnology are found in nearly all sectors of society from health care and food products to environmental issues and energy sources. Despite the significance of biotechnology within the sciences, it has not become a prominent trend in science education. In this study, we seek to more fully identify biology teachers’ concerns about biotechnology instruction and their reported practices. Consistent with the Stages of Concern framework as modified by Hord et al., we investigated teachers’ awareness, informational, personal, management, consequences, collaboration, and refocusing concerns about biotechnology teaching by employing a qualitative design that allowed for the emergence of teachers’ ideas. Twenty high school life science teachers attending a biotechnology institute were interviewed using an interview protocol specifically designed to target various Stages of Concern. Although the Stages of Concern framework guided the development of interview questions in order to target a wide range of concerns, data analysis employed a grounded theory approach wherein patterns emerged from teachers’ own words and were constantly compared with each other to generate larger themes. Our results have potential to provide guidance for professional development providers and curriculum developers committed to supporting initial implementation of biotechnology education. Recommendations include supporting teacher development of biotechnology content knowledge; promoting strategies for obtaining, storing and managing biotechnology equipment and materials; providing opportunities for peer teaching as a means of building teacher confidence; and highlighting career opportunities in biotechnology and the intersections of biotechnology and everyday life.     

The influence of golf shaft torque on clubhead kinematics and ball flight

ABSTRACT

The purpose of this study was to investigate the influence of shaft torque (torsional rigidity) on clubhead kinematics and the resulting flight of the ball. Two driver shafts with disparate levels of torque, but otherwise very similar properties, were tested by 40 right-handed golfers representing a range of abilities. Shaft deflection data as well as grip and clubhead kinematics were collected from 14 swings, with each shaft, for each golfer using an optical motion capture system. Ball flight and additional clubhead kinematics were collected using a Doppler radar launch monitor. At impact, the high torque shaft (HT) was associated with increased delivered loft (P = .028) and a more open face (P < .001) relative to the low torque shaft (LT). This resulted in the HT shaft being associated with a ball finishing position that was further right (P = .002). At the individual level, the change in face angle due solely to shaft deformation was significantly higher for the HT shaft for 25/40 participants. Although shaft twist was not directly measured, it was logically deduced using the collected data that these outcomes were the result of the HT being twisted more open relative to the LT shaft at impact.     

The labelling approach to deviance

Editor's note. In the 1970s Professor Nicholas Hobbs directed a comprehensive study on child classification while Provost at Vanderbilt University in the USA. Though neglected in recent years his 1975 edited text, 'Issues in the Classification of Children', remains a relevant and important source of thinking about categorisation. Given the current policy interest in categories of special educational need it seems appropriate to reconsider some of these ideas. The following article originally appeared as Chapter 4 from Volume One of the Hobbs text. It is reprinted here with the kind permission of the Hobbs family.
