The currency, relevancy and changing nature of science makes it a natural topic of focus for mass media outlets. Science teachers
and students can capitalize on this wealth of scientific information to explore socio-scientific and sustainability issues;
however, without a lens on how those media are created and how representations of science are constructed through media, the
use of mass media in the science classroom may be risky. Limited research has explored how science teachers naturally use
mass media to explore scientific issues in the classroom or how mass media is used to address potential overlaps between socio-scientific-issue
based instruction and education for sustainability. This naturalistic study investigated the reported and actual classroom
uses of mass media by secondary science teachers’ to explore socio-scientific and sustainability issues as well as the extent
to which their instructional approaches did or did not overlap with frameworks for SSI-based instruction, education for sustainability,
and media literacy education. The results of this study suggest that secondary science teachers use mass media to explore
socio-scientific and sustainability issues, but their use of frameworks aligned with SSI-based, education for sustainability,
and media literacy education was limited. This paper provides suggestions for how we, as science educators and researchers,
can advance a teaching and learning agenda for encouraging instruction that more fully utilizes the potential of mass media
to explore socio-scientific issues in line with perspectives from education for sustainability. 相似文献

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. 相似文献

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. 相似文献

ABSTRACTThe 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. 相似文献

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. 相似文献

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. 相似文献

The purpose of this study is to explore the reliability of a potentially more practical approach to direct writing assessment in the context of ESL writing. Traditional rubric rating (RR) is a common yet resource-intensive evaluation practice when performed reliably. This study compared the traditional rubric model of ESL writing assessment and many-facet Rasch modeling (MFRM) to comparative judgment (CJ), the new approach, which shows promising results in terms of reliability. We employed two groups of raters—novice and experienced—and used essays that had been previously double-rated, analyzed with MFRM, and selected with fit statistics. We compared the results of the novice and experienced groups against the initial ratings using raw scores, MFRM, and a modern form of CJ—randomly distributed comparative judgment (RDCJ). Results showed that the CJ approach, though not appropriate for all contexts, can be as reliable as RR while showing promise as a more practical approach. Additionally, CJ is easily transferable to novel assessment tasks while still providing context-specific scores. Results from this study will not only inform future studies but can help guide ESL programs in selecting a rating model best suited to their specific needs. 相似文献
