指向武术核心素养的中小学武术有效教学策略与方法设计     

柴广新  孙有平 《武汉体育学院学报》2020,54(4):87-92

为了有效促进学生武术核心素养的培育,针对我国武术教学中存在套路内容“繁难”、教法单一、重“形”轻“击”、重知识灌输,轻自主性培养、重教师的“教”,轻学生的“学”“学生不喜欢武术课”等一系列问题,提出了有效促进武术认知、武术运动能力、武术人格培育的原则,基于此原则,对“化难为易”策略、“化浅为深”策略、“化无趣为有趣”策略、“化技术为实践”策略、“知新温故”等策略进行了具体探索性设计,并对上述策略的具体实施方法进行了阐述,为中小学武术教学改革提供现实指导。  相似文献   

Priming urban learners' attitudes toward the relevancy of science: A mixed-methods study testing the importance of context     

Phillip A. Boda  Bryan Brown 《科学教学研究杂志》2020,57(4):567-596

The development of three-dimensional learning among all K-12 student demographics remains a prominent goal for the field of science education. However, substantial research in science teacher education for urban populations showcases hurdles to overcome in order to achieve this goal, particularly for elementary teachers. Research shows that urban elementary teachers are often ill-prepared to develop a type of science pedagogy responsive to students' learning needs. The fidelity of such pedagogies that these teachers adhere to when trying to implement such a requested content–relationality between these populations and how their local contexts can be used as sites to learn science in relevant ways are often not fully realized, as well. Given that science achievement gaps exhibit racial disparities starting in primary grades and attitudes toward science have been shown to affect academic achievement and motivation, we argue that one way to ameliorate, in at least an incremental way, this disparity is to design novel learning experiences to prime students to see the relevancy of science in their local contexts before such three-dimensional designed learning is set to occur. In this research, we leveraged the immersive nature of Virtual Reality 360 videos and present a design-based research iteration testing how this novel technologically enhanced learning experience may have influenced close to 400 urban elementary students' attitudes toward science around those attitudes labeled as “behavioral beliefs” by the field. Using a concurrent, convergent mixed-methods design with a two-way multivariate analysis of covariance quantitative data set triangulated with students' qualitative self-reports that were transformed into quantitative preponderances in graphic form, the data support that our design iteration emphasizing the importance of context as a design focus can prime students who struggle to see science as relevant to change their attitudes. Implications are discussed around relationality, novel technological affordances, and the use of local contexts as learning resources.  相似文献   

Developing higher-order reading skills in mainstream primary schools: A metacognitive and self-regulatory approach     

Taryn Moir  James Boyle  Lisa M. Woolfson 《British Educational Research Journal》2020,46(2):399-420

The ability to read relies upon not just decoding, but also comprehending text. Being a good comprehender requires strategic reading and implies the use of comprehension strategies. Research indicates that readers who are taught several reading comprehension strategies have better reading skills than those only taught a single strategy. One multiple strategy reading comprehension intervention was evaluated using a mixed-model quasi-experimental design. Intervention and control conditions groups were assessed at pre- and post-test points with standardised reading comprehension abilities, measured as the primary outcome measure. Implementation science principles were observed and evaluated. The schools all served areas of low socio-economic status. 74 pupils (aged 9–10) in five classes in four primary-level mainstream schools in a Scottish local authority were recruited as participants. Training was provided to participating schools by the first author and the programme was delivered in four sessions of 45 minutes per week for 8 weeks. An ANCOVA revealed a statistically significant effect of condition. Statistically significant scores were also evident in the secondary outcome measures of decoding of target word skills, children’s self-reports of their reading strategy use and recreational reading frequency. Implementation tools indicated that the intervention was acceptable and feasible to implement. Implications of introducing this multiple strategy reading comprehension programme and of the evaluation of implementation are discussed.  相似文献   

Sum of squares of deviations     

Josef Bukac  Jakub Sulc 《Teaching Statistics》2020,42(1):30-31

The question is whether or not we or any student are allowed to define a measure of variability in some other way that is not written in textbooks and officially approved. We compare the sum of squares of all deviations against the usual sum of squares of deviations from the mean.  相似文献   

The impact of student misconceptions on student persistence in a MOOC     

Chen Chen  Gerhard Sonnert  Philip M. Sadler  Dimitar Sasselov  Colin Fredericks 《科学教学研究杂志》2020,57(6):879-910

Massive Online Open Courses (MOOCs) provide opportunities to learn a vast range of subjects. Because MOOCs are open to anyone with computer access and rarely have prerequisite requirements, the range of student backgrounds can be far more varied than in conventional classroom-based courses. Prior studies have shown that misconceptions have a huge impact on students' learning performance; however, no study has empirically examined the relationship between misconceptions and learning persistence. This study of 12,913 MOOC-takers examines how students' misconceptions about the upcoming course material affect course completion. Using a survival analysis approach, we found that, controlling for the score in a pre-course test, students holding more misconceptions had a higher dropout rate at the start of the course, an effect that diminished over time. Other student variables were found to have a positive impact on survival that persisted throughout the entire course: U.S. location, higher age, an intention to complete, better English skills, prior familiarity with the subject, motivation to earn a certificate, and score and time spent on the previous problem set (homework). By contrast, student gender, education level, number of previous MOOCs completed, and motivation to participate in online discussion forums did not affect survival.  相似文献

Do private schools improve public school quality or increase stratification?     

《International Journal of Educational Development》2020

Utilizing a 4-year longitudinal dataset (2007−08 to 2010−11) of 212 public secondary schools from two districts in Nepal, I conduct panel regression analyses to determine the association between public school high stakes examination outcomes and measures of private sector competition. I find that there does not seem to be a significant positive or negative association between public school outcomes and the extent of private competition in recent years. However, there is evidence to suggest that the gap between public and private school outcomes is higher in localities with higher private sector growth, providing suggestive evidence of stratification.  相似文献   

University reform and the development of social sciences in Indonesia     

《International Journal of Educational Development》2020

Much has been studied regarding university reforms and their impacts on scientific development worldwide. This paper aims to enrich current perspectives on university reform by developing a distinct concept of social science development in the context of the emergence of academic social sciences in Indonesia. Using a bibliometric method, this paper finds a significant increase in the volume of international scientific publications focusing on socio-economic and political issues. However, two issues that presently color the landscape of social scientific publications are the bifurcation of academic dependencies and limited extension of Western social theories. The future of the social sciences in Indonesia will be determined by interrelationships between the state, universities, and networks of academics who can address the former issue and ensure that academics publish in mainstream international journals emphasizing the prominence of the latter. In doing so, the social sciences will have the potential to improve future university teaching and engagement in public policymaking in Indonesia.  相似文献   

动态助词“来”的历时发展及其衰落动因考察     

《信阳师范学院学报(哲学社会科学版)》2021,(5):124-130

古代汉语中,"来"的用法异常复杂,仅其助词属性下就又可以细分出六七种不同的用法,但这些用法大多并未能沿用到现代汉语共同语中,这也包括用作动态助词的"来"。从历时发展来看,动态助词"来"产生之后,在唐五代、宋元、明清三个阶段的使用并未呈现出持续上升的态势,而是在共同语中逐渐衰落了,今天仅在偏南方的一些方言中还有所使用。作为动态助词,"来"的衰落动因是多方面的,既有"来"自身功能负担过重,以及在使用中受限制过多的内因作用,也有系统内部成员竞争的外因作用。  相似文献
