Schools are an important context for both basic and applied scientific research. Unlike the laboratory, however, the physical and social conditions of schools are not under the exclusive control of scientists. In this article, we liken collecting data in schools to putting on a theatrical production. We begin by describing the large cast of characters whose collaborative efforts make school‐based research possible. Next, we address the critics, including the university Institutional Review Board (IRB) and school administrators, whose feedback often improves the final study design. We then turn our attention to set building, stage directions, and rehearsals—key steps in the iterative process of refining study procedures. We end with a discussion of the day of data collection itself and activities that take place after the curtain drops. Throughout, we make recommendations based on our recent experience collecting data at several high schools.  相似文献

Videos can be used as didactic tools for self‐learning under several circumstances, including those cases in which students are responsible for the development of this resource as an audiovisual notebook. We compared students' and teachers' perceptions regarding the main features that an audiovisual notebook should include. Four questionnaires with items about information, images, text and music, and filmmaking were used to investigate students' (n = 115) and teachers' perceptions (n = 28) regarding the development of a video focused on a histological technique. The results show that both students and teachers significantly prioritize informative components, images and filmmaking more than text and music. The scores were significantly higher for teachers than for students for all four components analyzed. The highest scores were given to items related to practical and medically oriented elements, and the lowest values were given to theoretical and complementary elements. For most items, there were no differences between genders. A strong positive correlation was found between the scores given to each item by teachers and students. These results show that both students' and teachers' perceptions tend to coincide for most items, and suggest that audiovisual notebooks developed by students would emphasize the same items as those perceived by teachers to be the most relevant. Further, these findings suggest that the use of video as an audiovisual learning notebook would not only preserve the curricular objectives but would also offer the advantages of self‐learning processes.

In recent years, there has been a growing interest in white matter anatomy of the human brain. With advances in brain imaging techniques, the significance of white matter integrity for brain function has been demonstrated in various neurological and psychiatric disorders. As the demand for interpretation of clinical and imaging data on white matter increases, the needs for white matter anatomy education are changing. Because cross‐sectional images and formalin‐fixed brain specimens are often insufficient in visualizing the complexity of three‐dimensional (3D) white matter anatomy, obtaining a comprehensible conception of fiber tract morphology can be difficult. Fiber dissection is a technique that allows isolation of whole fiber pathways, revealing 3D structural and functional relationships of white matter in the human brain. In this study, we describe the use of fiber dissection in combination with plastination to obtain durable and easy to use 3D white matter specimens that do not require special care or conditions. The specimens can be used as a tool in teaching white matter anatomy and structural connectivity. We included four human brains and show a series of white matter specimens of both cerebrum and cerebellum focusing on the cerebellar nuclei and associated white matter tracts, as these are especially difficult to visualize in two‐dimensional specimens and demonstrate preservation of detailed human anatomy. Finally, we describe how the integration of white matter specimens with radiological information of new brain imaging techniques such as diffusion tensor imaging tractography can be used in teaching modern neuroanatomy with emphasis on structural connectivity.

This pilot study examined the relations among preschool teachers' attitudes towards the inclusion of children with autism and perceived self‐efficacy, as well as demographic characteristics such as teachers' work experience and educational background. The cohort consisted of 21 participants who had degrees in preschool education and worked with children with autism in general preschool/kindergarten settings in central Sweden. Data were collected using the Autism Attitude Scale for Teachers, the Teacher Efficacy Scale and a demographic survey. In general, findings revealed that preschool teachers held positive attitudes towards children with autism, and this was significantly related to the number of credits in special education taken during pre‐service education. However, teachers showed neutral attitudes towards the inclusion of children with autism into general preschool classrooms. No relations were found between teachers' perceived self‐efficacy and attitudes towards inclusion, although a relationship was found between participation in in‐service training and efficacy to make decisions. Implications concerning early childhood education professional development and supervision are discussed.  相似文献

Lean six sigma is a management methodology that firms can employ to achieve substantial improvement in supply chain performance. However, few pedagogical exercises facilitate students’ use of a comprehensive set of lean six sigma principles within a supply chain context. We describe the Airplane Supply Chain Simulation that helps students understand how lean six sigma concepts may be leveraged to improve supply chain performance. The basis of this simulation is a four‐tier supply chain, consisting of suppliers (two tiers), a manufacturer, and a customer, that produces three models of paper airplanes to meet randomly distributed customer demand. In the first of three successive runs, a highly structured simulation is executed in which supply chain roles are well defined, material flows are convoluted, and a “push” production strategy is followed. The first simulation as the “current state” and, for the second and third simulation runs, challenge competing student teams to leverage lean six sigma concepts to develop a “future state” that enables the fulfillment of all customer orders at the lowest cost. Results based on statistical analyses of survey response data from 194 MBA students show that the Airplane Supply Chain Simulation is an effective participative, team‐based learning tool.  相似文献

Open access (OA) literature is digital, online, free of charge, and free of most copyright and licensing restrictions. The lack of clarity of publisher permissions for archiving in OA repositories affects the adoption of the green OA route. This paper explores editorial policies and self‐archiving conditions in 1,615 Spanish scholarly journals. 48% are published by university and research institutions, 25% by associations/societies, and 17% by commercial publishers; social sciences and humanities (SSH) accounted for 67% of the journals (44.5% and 22.5%, respectively) followed by health sciences (20%); 71% offered gratis access immediately after publication, and 11% after an embargo; 31% provided some mention of author rights. Self‐archiving was specifically allowed by 65% of the journals; 52% were classified as ROMEO‐blue, 12% as green and 15% as white, and 21% could not be classified; 21%, mostly in SSH, used some type of Creative Commons license.  相似文献

As Colombia began to develop its Intangible Cultural Heritage (ICH) policy, it signed an agreement with the Smithsonian Center for Folklife and Cultural Heritage to collaborate on a Smithsonian Folklife Festival of Colombia's national living traditions, to be shown on the National Mall in 2011. This essay addresses the role of the Smithsonian Folklife Center in advocating for a cultural heritage policy grounded in cultural democracy and intercultural dialogue, as well as its collaboration with UNESCO in crafting the 2003 convention for the protection of intangible cultural heritage. We focus on the Center's signature collaborative program, the Smithsonian Folklife Festival, and on our experience with the 2011 Festival program, Colombia: The Nature of Culture. We examine the relationship between the Festival and Colombia's intangible cultural heritage communities, policies, and practices, through intercultural dialogues that contribute to shaping Intangible Cultural Heritage policy from the bottom up.  相似文献
