Climate change is one of the most challenging problems facing today’s global society (e.g., IPCC 2013). While climate change is a widely covered topic in the media, and abundant information is made available through the internet, the causes and consequences of climate change in its full complexity are difficult for individuals, especially non-scientists, to grasp. Science education is a field which can play a crucial role in fostering meaningful education of students to become climate literate citizens (e.g., NOAA 2009; Schreiner et al., 41, 3–50, 2005). If students are, at some point, to participate in societal discussions about the sustainable development of our planet, their learning with respect to such issues needs to be supported. This includes the ability to think critically, to cope with complex scientific evidence, which is often subject to ongoing inquiry, and to reach informed decisions on the basis of factual information as well as values-based considerations. The study presented in this paper focused on efforts to advance students in (1) their conceptual understanding about climate change and (2) their socioscientific reasoning and decision making regarding socioscientific issues in general. Although there is evidence that “knowledge” does not guarantee pro-environmental behavior (e.g. Schreiner et al., 41, 3–50, 2005; Skamp et al., 97(2), 191–217, 2013), conceptual, interdisciplinary understanding of climate change is an important prerequisite to change individuals’ attitudes towards climate change and thus to eventually foster climate literate citizens (e.g., Clark et al. 2013). In order to foster conceptual understanding and socioscientific reasoning, a computer-based learning environment with an embedded concept mapping tool was utilized to support senior high school students’ learning about climate change and possible solution strategies. The evaluation of the effect of different concept mapping scaffolds focused on the quality of student-generated concept maps, as well as on students’ test performance with respect to conceptual knowledge as well as socioscientific reasoning and socioscientific decision making.  相似文献

The current four experiments investigated gaze following behavior in response to gaze and head turns in 4-month-olds and how reinforcement learning influences this behavior (N = 99). Using interactive eye tracking, infants’ gaze elicited an animation whenever infants followed a person’s head or gaze orientation (Experiment 1.1, 2.1 and 2.2) or looked at the opposite side (Experiment 1.2). Infants spontaneously followed the direction of a turning head with and without simultaneously shifted gaze direction (Cohen’s d: 0.93–1.05) but not the direction of isolated gaze shifts. We only found a weak effect of reinforcement on gaze following in one of the four experiments. Results will be discussed with regard to the impact of reinforcement on the maintenance of already existing gaze following behavior.  相似文献

Abstract

This paper examines the materials acquired during a consortial PDA pilot; which of the books are still being used, by which institutions, whether the size of a participating institution or the subject of a book have impact on the continued use of the books, and if there is a relationship between the schools that triggered a PDA purchase and the schools that have gone on to use a given title. Findings suggest that models involving some library mediation may be more effective in meeting the various needs of participating institutions.  相似文献

Cross-species comparison has long been regarded as a stepping-stone for medical research, enabling the discovery and testing of prospective treatments before they undergo clinical trial on humans. Post-genomic medicine has made cross-species comparison crucial in another respect: the 'community databases' developed to collect and disseminate data on model organisms are now often used as a template for the dissemination of data on humans and as a tool for comparing results of medical significance across the human-animal boundary. This paper identifies and discusses four key problems encountered by database curators when integrating human and non-human data within the same database: (1) picking criteria for what counts as reliable evidence, (2) selecting metadata, (3) standardising and describing research materials and (4) choosing nomenclature to classify data. An analysis of these hurdles reveals epistemic disagreement and controversies underlying cross-species comparisons, which in turn highlight important differences in the experimental cultures of biologists and clinicians trying to make sense of these data. By considering database development through the eyes of curators, this study casts new light on the complex conjunctions of biological and clinical practice, model organisms and human subjects, and material and virtual sources of evidence--thus emphasizing the fragmented, localized and inherently translational nature of biomedicine.  相似文献

In light of the growing role of social media in conflict management, the current study analyzes the interrelationship of online political participation of Israeli Jews, the frequency of their online contacts with Arabs, and Jews’ perceived social distances from Arabs. The research was conducted through an online survey of a representative sample of 458 Israeli Jews who use the social media at least 3 times a week. Overall, although causation cannot be inferred because of the correlational design of our study, results suggest that frequency of online contacts may positively affect closeness to Arabs in line with contact theory. In keeping with the socialization perspective of political engagement, the findings indicate that the impact of online political participation on social distances from Arabs was mediated by interactions between Jews and Arabs in the social media.  相似文献

In learning contexts, people need to make realistic confidence judgments about their memory performance. The present study investigated whether second-order judgments of first-order confidence judgments could help people improve their confidence judgments of semantic memory information. Furthermore, we assessed whether different personality and cognitive style constructs help explain differences in this ability. Participants answered 40 general knowledge questions and rated how confident they were that they had answered each question correctly. They were then asked to adjust the confidence judgments they believed to be most unrealistic, thus making second-order judgments of their first-order judgments. As a group, the participants did not increase the realism of their confidence judgments, but they did significantly increase their confidence for correct items. Furthermore, participants scoring high on an openness composite were more likely to display higher confidence after both the first- and second-order judgments. Moreover, participants scoring high on the openness and the extraversion composites were more likely to display higher levels of overconfidence after both the first- and second-order judgments. In general, however, personality and cognitive style factors showed only a weak relationship with the ability to modify the most unrealistic confidence judgments. Finally, the results showed no evidence that personality and cognitive style supported first- and second-order judgments differently.  相似文献

The objective of this study was to assess the prevalence of illicit drugs use among young adults, in particular elite athletes. This study considers the data obtained from anti-doping analyses performed on nearly 100,000 urine samples from 2000 to 2009 by the World Anti-Doping Agency accredited Italian Anti-Doping Laboratory. The percentage of adverse analytical findings varies on a yearly basis, but it is in the range 1.0-1.8% (not considering atypical findings, such as an altered endogenous steroid profile). Among positive results, there is a high prevalence of stimulants and drugs of abuse. The drug of abuse found most frequently is the tetrahydrocannabinol (cannabis) metabolite, accounting for 0.2-0.4% of the total samples analysed (18% of the positive results). The second most frequently encountered drug is cocaine, as detected from cocaine metabolites, accounting for 0.1% of the total samples analysed (7% of positive results). Other stimulants found included amphetamines, ephedrines, carphedon, modafinil, and anorexic compounds. No amphetamine-like designer drugs were detected. These data are indicative of the widespread prevalence of cocaine and cannabis use among the young adult population. However, due to the particular population studied, it must be considered an underestimation of the phenomenon among elite athletes with respect to the general population.  相似文献
