Constructing interactive web apps has become more accessible for instructors, for example, by using the R package Shiny. Here we explored learners' preferences and the efficiency of interactive simulations versus static pictures in acquiring statistics knowledge of Cohen's d and standard normal distribution. Results revealed that students' spontaneous interaction with pictures was infrequent (pilot study, N = 26). While prompts (Exp. 1, N = 152) effectively ensured the manipulation of simulations, student exposure to interactive simulations led to longer learning times though similar test performance compared with student exposure to static pictures. Multiple interactive representations led to lower test performance than single interactive and static representations (Exp. 2, N = 117). Though no advantage was gained regarding learning outcomes, participants preferred the interactive variant (Exp. 3, N = 119). Taken together, this study demonstrates that the superiority of interactive pictures cannot be assumed to hold in general. Further work should evaluate how mental model construction can be effectively scaffolded by interactive simulations. 相似文献

Numerous studies have confirmed direct health effects of interventions with a physical activity component on students without providing sufficient information on the contents or the degree to which the programs have been carried out. The empirical evidence of the indirect health effects of physical education is weaker. In this article the focus is placed on the evaluation of the indirect health effects, such as the enhancement of physical activity and its psychological determinants (e.g. motivation, attitudes, self-efficacy and knowledge) of the health promotion program HealthyPEP, using a quasi-experimental design with 516 sixth grade students. When taking into account the contents of HealthyPEP and the degree of implementation, it was clear that the program had different effects on the two genders whereby girls evaluated HealthyPEP in a more positive way compared to boys. In girls, positive tendencies were observed on rational cognitive determinants (e.g. knowledge and attitudes towards sports). The contents of HealthyPEP must be further optimized in the future to achieve positive indirect health effects also on boys. 相似文献

Can we train people to detect deception? It is the contention of this article that communication scholars should learn how to train law enforcement professionals on how to detect high stake lies, like those faced by police, judges, customs officials, immigration officials, and so forth. It is proposed that in order to know whether we can train or should bother to train people to detect deception, each training study must meet 6 challenges: (1) relevance, (2) high stakes, (3) proper training, (4) proper testing, (5) generalizability across situations, and (6) generalizability over time. Our quantitative review of the literature suggests that training does significantly raise lie detection accuracy rates. Meta-analytic findings indicate a mean effect size of r = .20 across 20 (11 published studies) paired comparisons of lie detection training versus the control group (i.e., those without some type of training). It should be noted that the majority of the studies that attempt to train lie detectors fall short on many of the above challenges. Current research in lie detection training may actually underestimate the ability to train lie detectors due to the stimulus materials employed in most experiments. 相似文献

It has become increasingly common for tasks traditionally carried out by engineers to be undertaken by technicians and technologist with access to sophisticated computers and software that can often perform complex calculations that were previously the responsibility of engineers. Not surprisingly, this development raises serious questions about the future role of engineers and the education needed to address these changes in technology as well as emerging priorities from societal to environmental challenges. In response to these challenges, a new design module was created for undergraduate engineering students to design and build temporary shelters for a wide variety of end users from refugees, to the homeless and children. Even though the module provided guidance on principles of design thinking and methods for observing users needs through field studies, the students found it difficult to respond to needs of specific end users but instead focused more on purely technical issues. 相似文献

Exploring the theory-practice gap in initial teacher education: moving beyond questions of relevance to issues of power and authority 总被引:1,自引:0,他引:1
The ‘theory-practice divide’ in teacher education can be viewed not simply as an acceptance of a body of knowledge but instead an acceptance of the teacher educator’s authority to determine what is relevant educational theory. This research aimed to explore student teachers’ views of ‘educational theory’ and how it was discursively positioned relative to their practice in an attempt to examine whether their acceptance or rejection of it was also related to accepting the authority of the teacher educator. Using one-to-one interviews with 23 student teachers and employing a discourse analysis, four categories of students emerged. The paper describes these four categories and discusses the implications of these findings for initial teacher education and our understanding of the ‘theory-practice’ gap. 相似文献

Through comparative statistical data of public investment trends in higher education, the institution of higher education in the US is contemporarily contextualized within the growing milieu of disparity. Specifically, this study focuses on the period from 1992 to 2007 to see if a mitigation of the growing economic disparity projected per the Kuznets curve was reflected in the prioritization of higher education support needed to preserve the social mobility of the workforce. Through the analysis of higher educational expenditure within the budgetary priorities of the 50 states from 1992 to roughly the present, this paper reveals that, in absolute terms or by disproportional emphasis, the institutional repositioning of higher education necessary for a Kuznets curve readjustment of disparity has not occurred. 相似文献

Assessment of the personalities of medical students could enable medical educators to formulate strategies for the best development of academic and clinical competencies. In this article, we focus on the experience of students in the anatomy dissecting room. While there have been many attempts to evaluate the emotional responses of medical students to human cadaveric dissection, there has been no investigation into how different personality traits affect the responses. The main hypothesis tested was that there is a relationship between personality traits and attitudes toward the dissection room. For the present study, a group of French medical students (n = 403; mean age 21.3 ± 1.6; 65.3% female) completed a "Big Five" personality inventory and a questionnaire to assess their attitudes in regard to human dissection. The findings are consistent with our hypothesis, in that we found a relationship between reporting anxiety and four of the "Big Five" dimensions (all except openness). The rated level of anxiety was positively correlated with negative affectivity, more strongly at the beginning than at the end of the course. There were significant gender differences in attitudes toward dissection. The findings are discussed in relation to the possibility of preparing students for the dissecting room experience and also in relation to the students' understanding of mortality issues. 相似文献
