Today, science is a major part of western culture. Discussions about the need for members of the public to access and understand scientific information are therefore well established, citing the importance of such information to responsible citizenship, democracy, socially accountable scientific research and public funding (National Research Council [2009] Learning science in informal environments: People, places, and pursuits. National Academies Press). In recent years there has been an increased interest in investigating not just what visitors to informal environments have learnt after a visit, but also how visitors interact and engage with exhibits during the visit (Davidsson & Jakobsson [2012] Understanding interactions at science centers and museums: Approaching sociocultural perspectives. Rotterdam: Sense Publishers). Within the field of school visits to science museums, however, interactions between students and museum educators (MEs) remain relatively unexplored. In our study of such school visits, we are mainly interested in the interactions that take place between three agents—the students, the museum educator and the physical setting of the exhibit. Using moment-to-moment fine grain analysis of multiple interactions allowed us to identify recurring patterns between students and the museum educators around exhibits, and to examine the MEs’ mediational role during the interactions, and the practices they employ to engage students with exhibits. Our study revealed that most interactions between MEs and students consist of technical explanations of how to operate the exhibits. The interactions that do move past this stage often include two main practices, which the MEs use to promote students’ engagement with the exhibits: physical instruction and engaging the students emotionally. Understanding what is actually happening in the learning process that occurs during students’ interactions with exhibits can help museum educators and exhibit designers improve the experiences of students on school visits. 相似文献

The effect of quantity and quality of reinforcement on performance change following a shift to uniform high reward was studied in four groups of rats. Twenty or 200 licks of a 5% or 20% sucrose solution constituted the four incentive conditions. Two additional subject groups were run in the high (20%–200 licks) and low (5%-20 licks) reward conditions to determine how amobarbital sodium, an emotional depressant, influences incentive shift performance. All six groups received 60 preshift runway trials (6/day), followed by 30 high reward trials. Twenty-four extinction trials contrasted drugged and normal performance relating to high and low reward Postshift positive contrast appeared in all nondrugged groups. An emotional base for positive contrast is considered. 相似文献

ABSTRACTBased on an in-depth qualitative content analysis of post-election discourse in three online creative communities (Scratch, Archive of Our Own, and hitRECord), we examine the significance of youth political expression in non-political online spaces, and its implications for civic education. We find that these spaces offer a valuable window into the main concerns experienced by youth around the election, which they voice through unique modes of expression. Online spaces facilitate connections between the personal and the political, while highlighting the social aspects of youth participation and learning in regard to civic issues. At the same time, participants exhibit uncertainty regarding the limits of online expression and the potential consequences of speaking out. We argue that online spaces should be acknowledged as a significant channel for youth political expression and socialization, and consider how the practices encountered there could shape our approach to civic education. 相似文献

AbstractIn this study, we suggest combining the monitoring of actual examination time used with grades in order to assess examination time extensions in terms of access provision and expected outcome. Using naturally-occurring data collected from a large sample (N?=?2315) of undergraduate engineering students, we argue that extended examination time may be regarded as providing equal access when a disabled student actually utilizes more examination time than a normally achieving student, regardless of the grade obtained. We further argue that extended examination time may be regarded as resulting in the expected outcome when a disabled student either (a) utilizes less or equal examination time and achieve grades that are lower than a normally achieving student, or (b) utilizes more examination time and achieve grades that are equal to a normally achieving student. In our data, equal access was provided in all courses (i.e. disabled students utilized more time than normal achievers), but the expected outcome (i.e. equal grades) was not observed in software and English examinations. The results of this study emphasize the importance of monitoring actual time usage in addition to performance measures when assessing examination time extensions. 相似文献

This laboratory activity was designed to strengthen our Food and Nutritional Science students’ knowledge of biochemistry concepts and the relationship between these concepts and food science. The result was a laboratory experience in which biochemistry concepts are taught using yogurt as a model, in order to link those concepts to food safety, an important area of food science. The students employed a colorimetric method to measure the lactase activity of bacterial strains found in commercial yogurts and were encouraged to relate the activity to bacterial lactic acid production, fermentation, and food safety. Students were assessed with pre‐ and post‐test exams, laboratory reports, class performance rubrics, and the Intrinsic Motivation Inventory (IMI). The result demonstrated that the students successfully completed the learning objectives and were motivated during the activity. This exercise could be used as a template for a simplified and engaging way to introduce food science majors, as well as other students, to complex biochemistry and molecular biology concepts using food, particularly yogurt, as a model. 相似文献
