Addressing Challenges to Public Understanding of Science: Epistemic Cognition,Motivated Reasoning,and Conceptual Change     

Gale M. Sinatra  Dorothe Kienhues  Barbara K. Hofer 《教育心理学家》2014,49(2):123-138

Science is of critical importance to daily life in a knowledge society and has a significant influence on many everyday decisions. As scientific problems increase in their number and complexity, so do the challenges facing the public in understanding these issues. Our objective is to focus on 3 of those challenges: the challenge of reasoning about knowledge and the processes of knowing, the challenge of overcoming biases in that reasoning, and the challenge of overcoming misconceptions. We propose that research in epistemic cognition, motivated reasoning, and conceptual change can help to identify, understand, and address these obstacles for public understanding of science. We explain the contributions of each of these areas in providing insights into the public's understandings and misunderstandings about knowledge, the nature of science, and the content of science. We close with educational recommendations for promoting scientific literacy.  相似文献   

Metabolic Thresholds and Validated Accelerometer Cutoff Points for the Actigraph GT1M in Young Children Based on Measurements of Locomotion and Play Activities     

Gerda Jimmy  Alain Dössegger  Roland Seiler  Urs Mäder 《Measurement in physical education and exercise science》2013,17(1):23-40

The purpose of the current study was to determine metabolic thresholds and subsequent activity intensity cutoff points for the ActiGraph GT1M with various epochs spanning from 5 to 60 sec in young children. Twenty-two children, aged 4 to 9 years, performed 10 different activities including locomotion and play activities. Energy expenditure was measured with indirect calorimetry. Thresholds and cutoff points were determined through receiver operating characteristic curves. The lower metabolic threshold was 6.19 kcal·kg^?1·h^?1 for moderate and 9.28 kcal·kg^?1·h^?1 for vigorous intensity. The cutoff points for the GT1M accelerometer appear to be lower than those for the previous model (7164). For 5-sec epochs, a cutoff point of 143 counts resulted for moderate intensity and of 208 counts for vigorous intensity activity. Whether short or long epochs were chosen when collecting data to determine cutoff points, does not appear to have an influence on the resulting cutoff values. Similarly, comparable results are seen when analyses are based on locomotion only as opposed to a wide range of activities including children's play.  相似文献   

Design,technology, and science: Sites for learning,resistance, and social reproduction in urban schools     

Gale Seiler  Kenneth Tobin  Joseph Sokolic 《科学教学研究杂志》2001,38(7):746-767

The teaching of science through activities that emphasize design and technology has been advocated as a vehicle for accomplishing science for all students. This study was situated in an inner7‐city neighborhood school populated mainly by African American students from life worlds characterized by poverty. The article explores the discourse and practices of students and three coteachers as a curriculum was enacted to provide opportunities for students to learn about the physics of motion through designing, building, and testing a model car. Some students participated in ways that led to their building viable model cars and interacting with one another in ways that suggest design and technological competence. However, there also was evidence of resistance from students who participated sporadically and refused to cooperate with teachers as they endeavored to structure the environment in ways that would lead to a deeper understanding of science. Analysis of in‐class interactions reveals an untapped potential for the emergence of a sciencelike discourse and diverse outcomes. Among the challenges explored in this article is a struggle for respect that permeates the students' lives on the street and bleeds into the classroom environment. Whereas teachers enacted the curriculum as if learning was the chief goal for students, it is apparent that students used the class opportunistically to maintain and earn the respect of peers. © 2001 John Wiley & Sons, Inc.

Activist dispositions for social justice in advantaged and disadvantaged contexts of schooling     

Carmen Mills  Trevor Gale  Stephen Parker  Catherine Smith  Russell Cross 《British Journal of Sociology of Education》2019,40(5):614-630

This article advances current conceptions of teacher activism through an exploration of the social justice dispositions of teachers in advantaged and disadvantaged contexts of schooling. We interrogate the practices of teachers in a government school, with a high proportion of refugee students and students from low socio-economic backgrounds, in a high-fees, multi-campus independent school, and in a disadvantaged Systemic Catholic school to illustrate how Bourdieu’s notion of dispositions (which are constitutive of the habitus) and Fraser’s distinction between affirmative and transformative justice are together productive of four types of teacher activism. Specifically, we show that activist dispositions can be characterised as either affirmative or transformative in stance and as either internally or externally focused in relation to the education field. We argue that the social, cultural and material conditions of schools are linked to teachers’ activist dispositions and conclude with the challenge for redressing educational inequalities by fostering a transformative activism in teachers’ practices.  相似文献   

Ranking economists on the basis of many indicators: An alternative approach using RePEc data     

Christian Seiler  Klaus Wohlrabe 《Journal of Informetrics》2012,6(3):389-402

In economics the Research Papers in Economics (RePEc) network has become an essential source for the gathering and the spread of both existing and new economic research. Furthermore, it is currently the largest bibliometric database in economic sciences containing 33 different indicators for more than 30,000 economists. Based on this bibliographic information RePEc calculates well-known rankings for authors and academic institutions. We provide some cautionary remarks concerning the interpretation of some provided bibliometric measures in RePEc. Moreover, we show how individual and aggregated rankings can be biased due to the employed ranking methodology. In order to select key indicators describing and assessing research performance of scientist, we propose to apply principal component analysis in this data-rich environment. This approach allows us to assign weights to each indicator prior to aggregation. We illustrate the approach by providing a new overall ranking of economists based on RePEc data.  相似文献

Teacher preferences for collaborative relationships: Relationship to efficacy for teaching in prevention-related domains     

Gale M. Morrison  Phylis Wakefield  Dorlene Walker  Scott Solberg 《Psychology in the schools》1994,31(3):221-231

Recent movements in educational reform call for increased collaborative activities among school personnel. The present study examines student and practicing teacher preferences for modes of working on a variety of student-related concerns and relationships with personal and general efficacy for teaching in prevention-related areas. Elementary and secondary student teachers and practicing teachers were asked to rate their preference for working on student academic, behavioral, and self-esteem problems. The range of working preferences included working with other professionals (collaborative), letting other professionals handle the problem (expert), and working alone. These working preferences were found to vary according to teacher level of experience and grade level of teaching. Significant relationships were found between collaborative work preferences and personal teaching efficacy.  相似文献
