播客在高等教育中的应用 总被引:1,自引:0,他引:1
播客已经成为高等教育领域一种流行的教学形式,然而,目前关于播客有效性的经验研究却很少。本研究的目的在于考查,对于高校学生来说,播客是否是一种有效的学习工具。研究关注教学播客所呈现内容的类型,以及这些播客所使用的教学方法。此外,我们还调查了学生所认为的有效的教学播客的特征,以及他们认为应该将播客用于哪些内容。我们分析了内容分析的结果,以及对学生的问卷调查结果,了解到教学播客作为高等教育学习工具的有效性,并明确了播客的未来研究方向。 相似文献

In this article we problematize the purpose of teaching science in preschool and the competences preschool teachers need in order to conduct science activities in the classroom. The empirical data were collected through an action research project with five preschool and primary school teachers (K-6). In the first section of this paper we use one situation, a floating–sinking experiment, as an illustration of how two different epistemological perspectives generate different foci on which kind of science teaching competences can be fruitful in preschool settings. In the first perspective, the central goal of science teaching is the development of the children’s conceptual understanding. With this perspective, we found that the science activities with children were unsuccessful, because their thoughts about concepts did not develop as expected, the situation even enhanced a “misconception” concerning density. Moreover, the teacher was unsuccessful in supporting the children’s conceptual learning. The second perspective uses a feminist approach that scrutinizes science, where we investigate if the floating–sinking activity contributes to a feeling of participation in a scientific context for the children and if so how the teacher promotes this inclusion. This second perspective showed that the children’s scientific proficiency benefited from the situation; they had a positive experience with density which was reinforced by the teacher. The children discovered that they had power over their own learning by using an experimental approach. On the basis of these findings, we conclude that there are competences other than subject matter knowledge that are also important when preschool teachers engage children in scientific activities. Through process-oriented work with the teacher group, we identified four concrete skills: paying attention to and using children’s previous experiences; capturing unexpected things that happen at the moment they occur; asking questions that challenge the children and that stimulate further investigation; creating a situated presence, that is, “remaining” in the situation and listening to the children and their explanations. We discuss possible ways to move preschool teachers away from their feelings of inadequacy and poor self-confidence in teaching science by reinforcing this kind of pedagogical content knowledge. 相似文献

This research introduces a new construct, gender‐based relationship efficacy, which refers to beliefs about one's ability to relate to own‐ and other‐gender peers. Study 1 investigated 204 fourth graders (M age = 9.56) and confirmed that own‐gender and other‐gender relationship efficacy represent distinguishable aspects of preadolescents' social competency beliefs that are differentially related to outcomes with own‐ and other‐gender peers, including outcome expectancies and friendships with own‐ and other‐gender peers. Study 2 provided further evidence of the distinctiveness of relationship efficacy for own‐ and other‐gender peers among 403 seventh (M age = 12.48) and 453 eighth (M age = 13.50) graders and found gender and age differences. Developmental changes and implications for research on intergroup relationships are discussed. 相似文献

While several innovative pedagogical practices have been developed and implemented in anatomy education since the onset of the coronavirus disease 2019 (Covid-19) pandemic, considering the value of in-person undergraduate dissection remains crucial. In this commentary, a human dissection course at the University of Toronto is used as an example to highlight the value of dissection for undergraduate learners in non-professional programs. In-person dissection allows for real life, anatomical variation, and supports the advancement of students' conceptual knowledge of the human body and visual–spatial abilities. Direct involvement with dissection during undergraduate training also provides students with an opportunity to practice and refine non-technical skills, such as communication and collaboration, while simultaneously promoting the development of students' professional identity formation. Further, dissection is a practical, hands-on experience that can provide students with insight into potential career aspirations related to anatomy and the health professions. It is suggested that as institutions veer from traditional pedagogical practices and evaluate how to best move forward post-pandemic, it is imperative that the value of undergraduate dissection is considered among new innovations in the field of anatomy. 相似文献

Introduction
Previous studies have implicated a strong link between circulating plasma resistin and coronary artery disease (CAD). The aim of this study was to evaluate the differences in peripheral blood mononuclear cells (PBMC) resistin mRNA and its plasma protein concentrations between the patients with CAD of different clinical severity.Material and methods
This study included 33 healthy subjects as the control group (CG) and 77 patients requiring coronary angiography. Of the latter 30 was CAD negative whereas 47 were CAD positive [18 with stable angina pectoris (SAP) and 29 with acute coronary syndrome (ACS)]. Circulating resistin was measured by ELISA; PBMC resistin mRNA was determined by real-time PCR.Results
Resistin protein was significantly higher in the ACS group compared to the CG (P = 0.001) and the CAD negative group (P = 0.018). Resistin mRNA expression did not vary across the study groups, despite the positive correlation seen with plasma resistin (ρ = 0.305, P = 0.008). In patients, plasma resistin and PBMC resistin mRNA negatively correlated with HDL-C (ρ = -0.404, P < 0.001 and ρ = -0.257, P = 0.032, respectively). Furthermore, the highest plasma resistin tertile showed the lowest HDL-C (P = 0.006). Plasma resistin was positively associated with serum creatinine (ρ = 0.353, P = 0.002).Conclusion
Significant increase of plasma resistin in patients with ACS compared to CG and CAD negative patients was observed. Despite no change in PBMC resistin mRNA in different disease conditions a positive association between resistin mRNA and resistin plasma protein was evident. Both plasma resistin and PBMC resistin mRNA were negatively associated with plasma HDL-C, and plasma resistin positively with serum creatinine.Key words: resistin, human; gene expression; coronary artery disease; acute coronary syndrome 相似文献108.
This correlational study examined the relationship between perceived task complexity and task interest for individuals with varying levels of domain knowledge and/or individual interest. Forty-five college student participants (46% women) reported their knowledge and individual interest in biology before learning about the biology of fungus. Following the task, participants rated the complexity and their understanding of the material. Participants took a quiz on the material and reported their interest in fungus and willingness to return for another session. A significant Biology Knowledge × Perceived Complexity interaction emerged on task interest and willingness to return for another session, ps < .05. Perceived complexity predicted positive task outcomes for high-domain-knowledge individuals but negative task outcomes for low-domain-knowledge individuals, suggesting that domain knowledge and individual interest can help explain individuals' diverse responses to learning activities. 相似文献

AbstractRecent years have witnessed a surge in evidence on preschoolers’ emotional development as crucial for both concurrent and later well-being and mental health, and for learning and academic success. Given the importance of building such strengths, assessing emotional competence skills is important to aid early childhood educators in focusing programming for individuals and classrooms. Based on these assertions, this article is structured as follows: (1) outline important issues regarding developmentally appropriate early childhood assessment, particularly of emotional competence; (2) discuss use of culturally relevant standards of attainment of such skills in assessing student progress; (3) define the skills of emotional competence; (4) describe a model leading from developmentally appropriate emotional competence skills to assessment and programming; (5) suggest some possible tools for schools to use in assessing emotional competence of young children; (6) give guidance for new measurement development, and (7) suggest needed policy and practice in this area. 相似文献
