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.     

Competition Out of Bounds: Sport in American Life

The 1992 NIH Research Planning Conference on Prosthetic and Orthotic Research for the 21st Century (Childress, 1992) recognized that the field of prosthetics lacks theoretical understanding and empirical studies on learning to control an upper-extremity prosthesis. We have addressed this problem using a novel approach in which persons without amputations are required to perform or learn basic motor tasks using a prosthetic simulator. The findings so far have three important implications for rehabilitation: (a) learning prosthetic control can be facilitated by general principles that have been shown to promote motor learning; (b) bilateral transfer can be used to enhance prosthetic limb control and minimize rejection; and (c) a voluntary closing terminal device has some advantages relative to a voluntary opening device     

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.     

An Examination of Changes to State Civic Education Requirements, 2004–2016

Across the country, states are considering policies that support civic learning among youth. Recent initiatives at the state level have changed graduation requirements and state assessments around high school civics. These initiatives can be grouped into three types: coursework, assessments, and accountability. The first type, coursework, refers to whether a state’s graduation requirements include a course in civics. The second, assessments, encompasses state requirements that students be assessed on civics or citizenship education. The third type, accountability, refers to whether a state’s accountability system includes state assessments in civics or citizenship education. The purpose of this study is threefold: (1) to describe state policies in civics education and the variation in them among the American states, (2) to document the changes in state policies between 2004 and 2016, and (3) to help unpack the reasons behind changes to civics education policy among the American states. We find considerable variation in civics education policies across states, as well as substantial changes within states over time. Using event history analysis, we exploit the variation to examine the extent to which political, economic, and demographic factors inside a state as well as the actions of neighboring or regional states condition adoption of assessment policies. We find evidence that the proportion of Hispanic and black populations in a state are positively associated with adoption and discuss implications and areas for future research.     

Approaches to Studying: age,gender and academic performance

A total of 245 business studies students (115 females and 130 males) responded to the Revised Approaches to Studying Inventory (RASI). Consistent with earlier studies, the purposes of the present study were (i) to examine some of the psychometric properties of the RASI; (ii) to investigate whether the RASI was predictive of academic success; and (iii) to investigate the effects of gender, age and programme of study on approaches to studying. The data were analysed using principal components factor analysis. The resulting fit of the RASI subscales to the hypothesised structure was good, thus providing support for the notions of deep, surface and strategic approaches and the lack of direction and academic self‐confidence orientations. The reliability of the ‘lack of direction’ subscale was low. The RASI's ability to predict academic performance investigated using a range of learning performance measures. These data were further analysed in terms of degree programme. Subjects’ mean scores on each of the scales were analysed in terms of age and gender. This revealed a number of significant effects. These findings, and the use of the RASI, are discussed in terms of their implications for the requirements for increased learner autonomy in further and higher education.
