Biology and Health Education     

Sheila Turner  Kristina Öberg  Gunilla Unnerstad 《欧洲师范教育杂志》1999,22(1):89-100

The Health Promoting Schools in Europe initiatives have highlighted the importance of health education in schools. Although health education is inter-disciplinary, biology teachers have an important role in teaching about health and in the formation of policy. Health education needs therefore to be part of initial teacher education programmes for those who are preparing to teach biology in secondary schools. Student teachers in England and Sweden have been involved in a pilot study that is investigating two aspects of teaching health education. The first element of the study has used questionnaires and small group discussions to explore biology student teachers’ perceptions of teaching about health as part of biology. In the second phase student teachers have been investigating secondary pupils’ understanding about aspects of health. In this paper we report on the initial findings and consider the implications of these results for the teaching of biology in secondary schools.  相似文献   

Modeling the Mediating Role of Volition in the Learning Process     

Teresa Garcia  Erin J. McCann  Jeannine E. Turner  Linda Roska 《Contemporary educational psychology》1998,23(4):392-418

According to action-control theory, volition plays a mediating role between the intention to learn (motivation) and goal-directed behavior (the use of learning strategies). Although extensive theoretical work has been done to document this flow of events, more empirical studies have been needed to identify the specific means by which volitional control protects the intention to learn and maintains the attempts to learn; our intention here was to address this gap in the literature. Using data from a sample of 487 college students in two different domains, we found that the positive effects of intrinsic goal orientation and self-efficacy on cognitive engagement were augmented by volitional control. We also found that the effects of volition differed by domain as well as by the type of learning strategy being considered. These results suggest that volitional control merits greater attention from those doing research in self-regulated learning.  相似文献   

Role Fulfillment Mediates the Association Between Daily Family Assistance and Cortisol Awakening Response in Adolescents

Family assistance (helping the family) is associated with both positive and negative psychological and biological outcomes during adolescence. However, the association between family assistance and the hypothalamic–pituitary–adrenal (HPA) axis remains unstudied. Thus, we assess how helping the family relates to adolescents’ diurnal cortisol, an index of HPA activity, and psychological outcomes. Three hundred and seventy ethnically diverse adolescents (ages 11–18) reported daily helping behaviors and psychological experiences for 14 days and provided four saliva samples per day for 4 days. Multilevel modeling revealed that cortisol awakening response was lower the day after adolescents helped their families more. This association was explained, in part, by perceived role fulfillment (feeling like a good son, daughter, and sibling). Results highlight a possible psychological and biological benefit of assisting the family during adolescence.  相似文献   

The NICE OECD countries' geographic search filters: Part 2—validation of the MEDLINE and Embase (Ovid) filters

Objective:We previously developed draft MEDLINE and Embase (Ovid) geographic search filters for Organisation for Economic Co-operation and Development (OECD) countries to assess their feasibility for finding evidence about the countries. Here, we describe the validation of these search filters.Methods:We identified OECD country references from thirty National Institute for Health and Care Excellence (NICE) guidelines to generate gold standard sets for MEDLINE (n=2,065) and Embase (n=2,023). We validated the filters by calculating their recall against these sets. We then applied the filters to existing search strategies for three OECD-focused NICE guideline reviews (NG103 on flu vaccination, NG140 on abortion care, and NG146 on workplace health) to calculate the filters'' impact on the number needed to read (NNR) of the searches.Results:The filters both achieved 99.95% recall against the gold standard sets. Both filters achieved 100% recall for the three NICE guideline reviews. The MEDLINE filter reduced NNR from 256 to 232 for the NG103 review, from 38 to 27 for the NG140 review, and from 631 to 591 for the NG146 review. The Embase filter reduced NNR from 373 to 341 for the NG103 review, from 101 to 76 for the NG140 review, and from 989 to 925 for the NG146 review.Conclusion:The NICE OECD countries'' search filters are the first validated filters for the countries. They can save time for research topics about OECD countries by finding the majority of evidence about OECD countries while reducing search result volumes in comparison to no filter use.  相似文献   

Team Shared Cognitive Constructs: A Meta‐Analysis Exploring the Effects of Shared Cognitive Constructs on Team Performance     

John R. Turner  Qi Chen  Shelby Danks 《Performance Improvement Quarterly》2014,27(1):83-117

Sharing similar cognitive structures among team members is one key element for the collective to solve problems and work more efficiently (DeChurch & Mesmer‐Magnus, 2010). Research has shown that team cognition is positively associated with team performance in both organizational and educational settings. Team shared cognition constructs are relatively new constructs and have been identified in the literature as team mental models, shared mental models, information sharing, transactive memory systems, cognitive congruence, and group learning. Cannon‐Bowers and Salas (2001) called for better measures of shared cognition to be developed, partially through the integration of shared cognition measures across disciplines. The purpose of this meta‐analysis is to look at these six team cognition constructs in an effort to help identify which measure, if any, results in predicting team performance best. Results indicated that information sharing was statistically significant compared to team mental memory and group learning, and marginally significant compared to transactive memory systems. Additionally, shared mental models and cognitive congruence showed higher associations with performance compared to team mental models, group learning, and transactive memory systems.  相似文献
