Elementary Teachers’ Selection and Use of Visual Models     

Tammy D. Lee  M. Gail Jones 《Journal of Science Education and Technology》2018,27(1):1-29

As science grows in complexity, science teachers face an increasing challenge of helping students interpret models that represent complex science systems. Little is known about how teachers select and use models when planning lessons. This mixed methods study investigated the pedagogical approaches and visual models used by elementary in-service and preservice teachers in the development of a science lesson about a complex system (e.g., water cycle). Sixty-seven elementary in-service and 69 elementary preservice teachers completed a card sort task designed to document the types of visual models (e.g., images) that teachers choose when planning science instruction. Quantitative and qualitative analyses were conducted to analyze the card sort task. Semistructured interviews were conducted with a subsample of teachers to elicit the rationale for image selection. Results from this study showed that both experienced in-service teachers and novice preservice teachers tended to select similar models and use similar rationales for images to be used in lessons. Teachers tended to select models that were aesthetically pleasing and simple in design and illustrated specific elements of the water cycle. The results also showed that teachers were not likely to select images that represented the less obvious dimensions of the water cycle. Furthermore, teachers selected visual models more as a pedagogical tool to illustrate specific elements of the water cycle and less often as a tool to promote student learning related to complex systems.  相似文献   

Exploring undergraduates' understanding of photosynthesis using diagnostic question clusters     

Parker JM  Anderson CW  Heidemann M  Merrill J  Merritt B  Richmond G  Urban-Lurain M 《CBE life sciences education》2012,11(1):47-57

We present a diagnostic question cluster (DQC) that assesses undergraduates' thinking about photosynthesis. This assessment tool is not designed to identify individual misconceptions. Rather, it is focused on students' abilities to apply basic concepts about photosynthesis by reasoning with a coordinated set of practices based on a few scientific principles: conservation of matter, conservation of energy, and the hierarchical nature of biological systems. Data on students' responses to the cluster items and uses of some of the questions in multiple-choice, multiple-true/false, and essay formats are compared. A cross-over study indicates that the multiple-true/false format shows promise as a machine-gradable format that identifies students who have a mixture of accurate and inaccurate ideas. In addition, interviews with students about their choices on three multiple-choice questions reveal the fragility of students' understanding. Collectively, the data show that many undergraduates lack both a basic understanding of the role of photosynthesis in plant metabolism and the ability to reason with scientific principles when learning new content. Implications for instruction are discussed.  相似文献   

‘They have different information about what is going on’: emotion in the transition to university     

Wendy McMillan 《高等教育研究与发展》2014,33(6):1123-1135

Most new students experience school to university transition as challenging. Students from backgrounds with little or no experience of higher education are most vulnerable in this transition, and most at risk of academic failure. Emotion appears implicated in the differential way in which first-generation students and students with family familiarity of university experience the transition. This article draws on the voices of first-year dental and oral hygiene students at a South African dental faculty regarding university transition experiences. It draws on the construct of capital and Archer's [(2002). Realism and the problem of agency. Journal of Critical Realism Alethia, 5(1), 11–20] understanding of ‘competing concerns’ to examine how emotion shapes students' experiences of university transition and how they position themselves with regard to these experiences. The article explicates the ways in which emotional commentary and classed locations intersect, exploring the extent to which this intersection shapes young people's framing of their concerns of ‘being a student’ and ‘becoming a dentist’. The article identifies aspects of the university's material and cultural environments which shape students' emotional responses and which consequently are implicated in the perpetuation of class-based differential life chances.  相似文献   

How Moroccan mothers and fathers view child development and their role in their children's education     

Gail L. Zellman  Michal Perlman  Rita Karam 《International Journal of Early Years Education》2014,22(2):197-209

Despite the documented importance of parental engagement in early learning, little is known about how parents in the Middle East and North Africa understand child development. To inform the literature, a small-scale study involving four focus groups was conducted with parents of children aged six years and under living in Casablanca. The purpose of this study was to explore parents' understanding of and support for their children's early development. Results reveal that parents see a vital role for themselves in their children's upbringing as supporters and nurturers, but little role as teachers. Across different education and income levels, parents in this small-scale qualitative study believe that children's experiences in their first years of life do not affect their longer-term intellectual development or school success and see little value in early intellectual stimulation or formal preschool education. Our results suggest that parents need to understand their role as their child's first educators. Also, it is essential that parents are taught how to promote their children's early cognitive development without undermining their nurturing roles.  相似文献

Project Transfer: A Publisher's Perspective     

Ian Bannerman  Nancy Buckley  Jennifer McMillan 《期刊图书馆员》2013,64(3):411-418

The Transfer Code of Conduct is designed to improve the process of journal transfer between publishers. It was launched by the UKSG (United Kingdom Serials Group) in May 2007. Taylor & Francis is one of eight publishers to support the project. It is different from previous initiatives in that it was created by publishers, librarians, and intermediaries, and it aims to provide a firmer, more practical set of guidelines than those that have been published previously. Despite a strong initial take-up, the Code has not yet been endorsed by some of the larger publishers and trade bodies. These organizations are now working with Transfer to re-draft the Code of Conduct. Once this is in place, further measures are planned to track journal transfer and monitor compliance. Long-term governance of Transfer is also being considered.  相似文献   

Teachers’ Concepts of Spatial Scale: An international comparison     

M. Gail Jones  Manuela Paechter  Chiung-Fen Yen  Grant Gardner  Amy Taylor  Thomas Tretter 《International Journal of Science Education》2013,35(14):2462-2482

Metric scale is an important concept taught as part of science curricula across different countries. This study explored metric and relative (body-length) scale concepts of inservice (N?=?92) and preservice (N?=?134) teachers from Austria, and Taiwan, and their concepts were compared with those of teachers from the USA. Participants completed three assessments: the Scale Anchoring Objects (SAO), Scale of Objects Questionnaire (SOQ), and a subsample of participants were interviewed with the Learning Scale Interview. A Rasch analysis was conducted with the SAO and SOQ and results showed that the Rasch model held for these assessments, indicating that there is an underlying common dimension to understanding scale. Further analyses showed that accuracy of knowledge of scale measured by the SAO and SOQ was not related to professional experience. There were significant differences in teachers’ accuracy of scale concepts by nationality. This was true for both metric and body-length SAO assessments. Post hoc comparisons showed that the Austrian and Taiwanese participants were significantly more accurate than the US sample on the SAO and SOQ. The Austrian participants scored significantly higher than the US and the Taiwanese participants. The results of the interviews showed that the Taiwanese experienced teacher participants were more likely to report learning size and scale through in-school experiences than the Austrian or the US participants. US teachers reported learning size and scale most often through participating in hobbies and sports, Taiwanese teachers reported learning scale through sports and reading, and Austrian teachers most often noted that they learned about scale through travel.  相似文献
