Supporting groups’ emotion and motivation regulation during collaborative learning     

《Learning and Instruction》2020

This study investigates when and how students activate co- and socially shared emotion and motivation regulation in collaborative learning and whether the S-REG mobile application tool can support this regulation. In a mathematics course, 44 higher education students worked with a collaborative assignment. The S-REG tool traced groups' emotional and motivational states in different sessions, and the occurrence of co-regulation and shared regulation of motivation and emotions were coded from video-recorded collaborative work (44 h). The groups activated more co-regulation than shared regulation of emotions and motivation, but the shared-regulation episodes were longer-lasting. The groups’ emotional and motivational states were associated with the occurrence of co-regulation in the beginning of the learning sessions. The results suggest that the S-REG tool balanced collaboration by prompting the groups to regulate emotions and motivation right in the beginning of the motivationally and emotionally challenging learning sessions.  相似文献   

我国高危险性体育项目的立法缺陷及其完善     

汪全胜  宋琳璘  张奇 《武汉体育学院学报》2020,54(6):46-53

高危险性体育项目相对一般体育项目而言，是具有危险性大、专业技术性强、安全保障要求高等特点的体育活动。我国对高危险性体育项目有一定的法律规制，但存在顶层设计缺失、法律制度之间的冲突与不一致、可操作性不足等问题。这些制度缺陷产生的根源在于对立法必要性的认识不足、立法不作为，缺乏有效的立法监督机制等，现有制度的缺陷与不足会影响我国高危险性体育项目的发展，难以满足人们体育文化活动的需要。鉴于此，我国应逐步完善高危险性体育项目的法律规制，包括完善高危险性体育项目的审定主体，明确经营高危险性体育项目的主体范围、完善高危险性体育项目的行政许可条件、强化高危险体育项目行政监管以及风险防范等。  相似文献

代谢工程研究的主要目的是通过改造菌株代谢网络,高效地合成目的产品。由于细胞代谢网络的复杂性,从数千个代谢反应及其调控回路中找到合适的改造靶点非常困难,往往要经过反复试差才能成功。通过对大规模代谢网络的计算分析,设计出特定生物产品的最优合成途径,可以帮助人们找出合适的代谢工程改造策略,减少改造过程的盲目性,更快更好地得到生物合成菌株。文章重点讨论两个问题:(1)如何设计代谢网络来合成原来不能合成的产品并提高产品得率,介绍了基于代谢网络计算分析的代谢工程设计方法;(2)如何设计菌株实现酶反应的精准调控,介绍了通过设计基因回路动态调控代谢途径流向的动态代谢工程研究新进展。  相似文献   

高强度的环境规制能够促进国内大气科技创新吗？——以〖SO〗_2排放控制技术为例          下载免费PDF全文

林玲  赵子健  曹聪丽 《科研管理》2018,39(12):45-52

从理论上来说，波特弱假说涉及双重外部性问题，即大气污染的负外部性和技术创新的正外部性，环境规制和知识产权保护合力才能予以切实彻底解决，而后者并没有得到普遍重视。本文认为，波特弱假说需要考虑知识产权保护强度。以SO_2排放控制技术为例，本文运采用2000-2013年省际省份面板数据，结合固定效应模型进行实证研究检验了知识产权保护对于波特弱假说的作用。结果发现，当知识产权保护较弱时，环境规制对大气科技创新具有呈现负向影响；。只有当知识产权保护较强时力度超过一定阈值时，环境规制才会对大气科技创新产生正向影响，波特弱假说成立。此外，环境规制和知识产权保护影响大气科技创新的交叉效应主要出现在企业，而非科研院所和个人，创新主体存在明显的差异性。  相似文献   

Students’ and teachers’ monitoring and regulation of students’ text comprehension: Effects of comprehension cue availability     

《Contemporary educational psychology》2019

For regulation of text learning to be effective, students need to accurately monitor their text comprehension. Similarly, to provide adaptive instruction, teachers need to accurately monitor and regulate students’ text comprehension. Performing generative activities prior to monitoring has been suggested to provide students with diagnostic cues, improving monitoring accuracy; an open question is whether this would also help teachers. We investigated whether two generative activities, diagram completion and diagram drawing, improved secondary education students’ (n = 248) monitoring and regulation accuracy of text comprehension (Experiment 1) and whether viewing students’ diagrams improved teachers’ (N = 18) monitoring and regulation of students’ text comprehension (Experiment 2). Students’ monitoring and teachers’ regulation accuracy was higher in the diagramming conditions than in the no-diagramming condition. Students and teachers used diagnostic cues when judging students’ text comprehension: Improving students’ monitoring and teachers’ regulation of students’ text comprehension relies on improving accessibility of diagnostic cues.  相似文献   

Exploring the effects of web-mediated socially-shared regulation of learning and experience-based learning on improving students’ learning     

Chia-Wen Tsai  Pei-Di Shen  I-Chun Chiang  Wen-Yu Chen  Yi-Fen Chen 《Interactive Learning Environments》2018,26(6):815-826

The application of online learning and educational technologies in higher education has changed teaching methods, the channels of delivering learning materials, and modes of communication between teachers and students. This study is aimed to improve learning effects and investigate, via quasi-experiments, the effects of web-mediated socially-shared regulation of learning (SSRL) and experience-based learning (ExBL) on improving students’ learning results. The experimental design in this study was a 2 (SSRL vs. non-SSRL)?×?2 (ExBL vs. non-ExBL) factorial pretest/post-test design. Four classes in a one-semester course titled “Applied Information Technology: Data Processing” at university level were chosen for this study. Based on the analysis carried out in this study, students who received the treatments of web-mediated SSRL and/or ExBL did not have significantly better computing skills in using Excel. The reasons for these insignificances and implications thereof are discussed in this paper. Nevertheless, students in the SSRL and non-ExBL class had significant increases in scores for their learning motivation at the end of semester compared with the beginning.  相似文献   

困境与出路：我国性侵运动员犯罪行为的刑事规制探究          下载免费PDF全文

王桢 《河北体育学院学报》2019,33(1):19-27

近年来，性侵运动员的犯罪行为频发，成为国际社会聚焦的热点。以此审视我国运动员性法益的保护，虽有强奸罪、强制猥亵罪的刑事立法，却缺乏对该犯罪行为特殊性的深入思考，既不能在惩治犯罪人方面达到理想效果，亦不能在预防犯罪方面发挥良好功能。同时，司法中的“以纪代法”、针对性缺乏、未回应被害人需求等诸多问题，亦使该犯罪行为的刑事规制效果大打折扣。所以，在该犯罪立法上应有针对性采用附属刑法进行修正，完善犯罪的特别预防与一般预防制度；司法上，积极回应被害人的诉求，努力克服刑事规制过程中的各种困境，让运动员的性法益得到全面而充分的保护。  相似文献   

Emotion regulation and motor performance: an integrated review and proposal of the Temporal Influence Model of Emotion Regulation (TIMER)     

Garrett F. Beatty  Christopher M. Janelle 《International review of sport and exercise psychology》2020,13(1):266-296

ABSTRACT

Adaptive regulation of emotions is imperative for successful sport performance. However, the lion’s share of mainstream emotion regulation (ER) literature is founded on perspectives prioritising mental health, not performance. Consequently, ER strategies are predominantly classified as adaptive or maladaptive based on effectiveness in achieving targeted mental health outcomes. These conventional mental health classifications can catalyse misapplication of ER strategies within sport and other motor performance contexts when (1) ER motives are instrumentally directed towards performance enhancement and (2) Minimal consideration is given to the consequences of ER on the coordination and execution of motor actions. Herein, we review the current state of relevant ER research within and outside of sport contexts. We also present a novel conceptual framework, the Temporal Influence Model of Emotion Regulation (TIMER). TIMER proposes that ER strategies exert distinct, temporally dependent demands upon perceptual-cognitive and motoric resources. These unique regulatory profiles influence subsequent motor performance outcomes. Critically, the degree to which regulatory strategies are appropriate or ideal varies given environmental constraints along with performers’ affective and performance goals. The model includes testable hypotheses to guide theoretical and applied research in the domain of ER within sport and other motor performance contexts.  相似文献   

挑战、困境与化解:数字环境下我国图书馆合理使用条款及其适用的再探讨     

王果  张立彬 《图书情报工作》2019,63(10):5-11

[目的/意义] 合理使用是维持著作权人个人利益与社会公共利益平衡的重要机制之一，对承担公共文化服务功能的图书馆尤为重要，但实践中图书馆的合理使用条款并未充分发挥利益平衡的作用，有必要对其存在问题及形成原因进行深入分析。[方法/过程] 通过与域外立法相比较，以及司法实践中的案例分析，可看出我国图书馆合理使用的主要问题在于现行法律规定滞后、规则不明晰，导致合理使用适用范围狭窄，还同时受到许可协议、技术措施的挤压。[结果/结论] 为化解图书馆合理使用条款的适用困境，可从增加原则性规定、明确其法律属性为强制性规定、扩大有关条款的适用范围等方面来完善立法。图书馆自身也应加强知识产权管理、提高知识产权素养，严格遵照法律规定以消除侵权隐患。  相似文献
