This paper explores some of the processes through which an educational policy agenda can be generated in the media sphere. It casts light on the roles of journalists and various types of expert in these processes as they pertain to critical literacy. I argue for the usefulness of cross-field performance as a concept which helps to illuminate the special place of individuals who position themselves across journalistic, academic and political fields. The analysis is supported by examination of patterns in newspaper reporting and academic publication, which suggests that contestation of critical literacy serves as a staging device for a team of policy entrepreneurs, whose performances work to discredit and exclude other players. 相似文献

Despite the impact of genetics on daily life, biology undergraduates understand some key genetics concepts poorly. One concept requiring attention is dominance, which many students understand as a fixed property of an allele or trait and regularly conflate with frequency in a population or selective advantage. We present the Dominance Concept Inventory (DCI), an instrument to gather data on selected alternative conceptions about dominance. During development of the 16-item test, we used expert surveys (n = 12), student interviews (n = 42), and field tests (n = 1763) from introductory and advanced biology undergraduates at public and private, majority- and minority-serving, 2- and 4-yr institutions in the United States. In the final field test across all subject populations (n = 709), item difficulty ranged from 0.08 to 0.84 (0.51 ± 0.049 SEM), while item discrimination ranged from 0.11 to 0.82 (0.50 ± 0.048 SEM). Internal reliability (Cronbach''s alpha) was 0.77, while test–retest reliability values were 0.74 (product moment correlation) and 0.77 (intraclass correlation). The prevalence of alternative conceptions in the field tests shows that introductory and advanced students retain confusion about dominance after instruction. All measures support the DCI as a useful instrument for measuring undergraduate biology student understanding and alternative conceptions about dominance. 相似文献

This paper proposes that Kelly's Personal Construct Psychology deserves examination as a constructivist basis for science
teaching and learning. It argues that because of the explicit nature of the psychology, the clear definition of learning and
meaning and the integration of affective, psychomotor and cognitive dimensions of learning, the psychology has much to offer
science education. 相似文献

Believe that the findings and recommendations of the Elton Committee have much to offer schools for children with emotional and behavioural difficulties, as well as mainstream schools. They outline the way they have introduced 'assertive discipline' into behaviour management policy of the school. 相似文献
