Researchers and practitioners have suggested that the use of social networking sites in formal education may be a worthwhile endeavor. Toward this goal, emerging learning platforms have included social networking features. Nevertheless, empirical literature examining user experiences, and more specifically instructor experiences, with these tools is limited. In this qualitative study, we address this gap in the literature by reporting the experiences of five instructors who used a social networking platform in their courses. We find that instructors (a) had expectations of Elgg that stemmed from numerous sources, (b) used Elgg in heterogeneous ways and for varied purposes, (c) compartmentalized Elgg and used it in familiar ways, and (d) faced frustrations stemming from numerous sources. We note that the ways Elgg came to be used “on the ground” is contested and contrasts starkly with the narrative of how social software might contribute benefits to educational practice. In addition, we note that learning management systems may frame the ways through which other tools, such as social media and Elgg, are understood, used, and experienced. 相似文献

Many of the concepts and principles used in cybernetics are helpful in examining and designing instructional systems. However, the operational utility of cybernetic models is dependent on the match between the phenomenon being modelled and the model itself. In this paper, the position is taken that except in those forms of learning where the criteria for success are independent, fixed, and few in number, the cybernetic paradigm cannot be applied to curriculum development without a modified interpretation of how evaluation criteria can act as system control variables. 相似文献

Three emotionally divergent strains of mice (SWR/J, A/HeJ, and SJL/J) were mated to produce three populations: a pure strain population (N = 90), an F1 population (N = 120), and an F2 population (N = 96). All Ss were tested on a battery of measures of emotionality. Each population was factored separately by principal components factoring with varimax and promax rotations. Factorial invariance was assessed quantitatively by congruence coefficients. Eight of the resultant factors were found to be replicable across populations. These were autonomic balance, motor discharge, territorial marking, acrophobia, tunneling-1, tunneling-2, underwater swimming, and audiogenic reactivity. Of the eight factors, motor discharge was most distinct in each population and tunneling-1 was least distinct. 相似文献

We report on a survey of K-12 teachers and teacher candidates wherein participants evaluated known models (e.g., TPACK, SAMR, RAT, TIP) and provided insight on what makes a model valuable for them in the classroom. Results indicated that: (1) technology integration should be coupled with good theory to be effective, (2) classroom experience did not generally influence teacher values and beliefs related to technology integration, (3) some models may be more useful to teachers than others, (4) the widespread use of a model does not necessarily reflect usefulness, (5) useful models for teachers should engender real-world, concrete application, and (6) visual appeal of a model is largely subjective, but some visual representations might convey notions of practicality. Conclusions should be used to help researchers and practitioners understand the practical application value of technology integration models in real-world settings. 相似文献

Abstract Fatigue curves for the forearm muscles, doing maximal static and dynamic work, were obtained under control conditions and under conditions of hyperaemia. The hyperaemia was evoked by subjecting the muscles of the forearm for a specific length of time to circulatory occlusion with a blood pressure cuff and then suddenly releasing the cuff pressure. The maximal increase in forearm volume, resulting from the postocclusion hyperaemia, followed a mathematical curve when it was expressed as a function of the occlusion time. A significant decrement in work capacity was found immediately after ten minutes of occlusion. This short-time negative influence did not affect the total output. 相似文献

This study utilizes public data mining to explore participation divides of all available K-12 institutional Twitter accounts in the U.S. (n?=?8275 accounts, n?=?9,216,853 tweets). Results indicated that U.S. schools used Twitter to broadcast information on a variety of topics in a unidirectional manner and that hashtags included a variety of intended purposes, including affinity spaces, education topics, emotive language, and events. Those schools in wealthier, more populated areas were more likely to use Twitter, with wealthy, suburban schools being the most likely to use it and poor, rural schools being the least likely. Furthermore, factors such as charter school status and urbanity influenced the content of school tweets on key issues, with schools in more populated areas tweeting more about coding and college than schools in less populated areas and charter schools tweeting more about college and the politicized educational issue of common core than non-charters. These results reveal participation differences between schools based upon demographics and provides a basis for conducting future large-scale work on publicly available artifacts, such as school tweets, that may be meaningfully used as education research data. 相似文献
