Student evaluations of teaching are ubiquitous and impactful on the careers of college teachers. However, there is limited empirical research documenting the accuracy of people’s efforts in interpreting teaching evaluations. The current research consisted of three studies documenting the effect of small mean differences in teaching evaluations on judgements about teachers. Differences in means small enough to be within the margin of error significantly impacted faculty members’ assignment of merit-based rewards (Study 1), department heads’ evaluation of teaching techniques (Study 2) and faculty members’ evaluation of specific teaching skills (Study 3). The results suggest that faculty and administrators do not apply appropriate statistical principles when evaluating teaching evaluations and instead use a general heuristic that higher evaluations are better. 相似文献

In Northern Costa Rica, agricultural production conditions change very rapidly due to public policies that encourage the exportation of new crops according to the liberalization process imposed by the international context. For many years, farmers' organizations at the local, regional and national levels have taken initiatives to respond to this new context and develop relationships with institutions (the Ministry of Agriculture, national universities, NGOs, international agencies, the private sector) promoting innovations and attaining better access to information, training and financial resources. An action-research program, ‘Aid to Farmer's Organization of Northern Costa Rica’, contributes to the strengthening of farmers' organizations and tries to induce change dynamics through the elaboration of a shared vision of peasant agriculture implying the production of safe food, the protection of natural resources, the development of qualified local employment and the defense of the rural culture. The present paper will analyze the dynamics of such a collective action. Action is structured around various activities such as the exchange of experiences between farmers' organizations, the elaboration of a common vision on the future of family agriculture between different actors, the training of the members and leaders of organizations and the design and implementation of innovative project. This collective action induces the construction of new and useful knowledge, changes in the relationships between the actors, the implementation of new institutional mechanisms and the development of new rules inside and outside the organizations. 相似文献

EXPANDING YOUNG PEOPLE'S CAPACITY TO LEARN 总被引:1,自引:1,他引:1
Abstract: Though it is being widely argued that expanding young people's capacity to learn is a viable and desirable goal of education, it it not always clear what this means, how it is to be achieved, and how the effectiveness of interventions is to be assessed. It is argued that the capacity to learn should be interpreted as a portmanteau term that comprises a varied set of positive learning dispositions. These are illustrated, and the idea of 'expansion' is glossed in terms of broadening, strengthening and deepening these dispositions. 相似文献

A new lighting and enlargement on phase spectrogram (PS) and frequency spectrogram (FS) is presented in this paper. These representations result from the coupling of power spectrogram and short time Fourier transform (STFT). The main contribution is the construction of the 3D phase spectrogram (3DPS) and the 3D frequency spectrogram (3DFS). These new tools allow such specific test signals as small slope linear chirp, phase jump case of musical signal analysis is reported. The main objective is to and small frequency jump to be analyzed. An application detect small frequency and phase variations in order to characterize each type of sound attack without losing the amplitude information given by power spectrogram 相似文献

In this paper we demonstrate a new method for concentrating the set of key-words of a thesaurus. This method is based on a mathematical study that we have carried out into the distribution of characters in a defined natural language.We have built a function f of concentration which generates only a few synonyms. In applying this function to the set of key-words of a thesaurus, we reduce each key-word to four characters without synonymity. (For three characters we have a rate of synonymity of approx. 1/1000th.)A new structure of binary files allows the thesaurus to be contained in a table of less than 700 bytes. 相似文献

This article deconstructs the online and offline experience to show its complexities and idiosyncratic nature. It proposes a theoretical framework designed to conceptualise aspects of meaning-making across on- and offline contexts. In arguing for the ‘(im)materiality’ of literacy, it makes four propositions which highlight the complex and diverse relationships between the immaterial and material associated with meaning-making. Complementing existing sociocultural perspectives on literacy, the article draws attention to the significance of relationships between space, mediation, materiality and embodiment to literacy practices. This in turn emphasises the importance of the subjective in understanding how different locations, experiences and so forth inflect literacy practice. The article concludes by drawing on the Deleuzian concept of the ‘baroque’ to suggest that this focus on articulations between the material and immaterial helps us to see literacy as multiply and flexibly situated. 相似文献

Verstaen, Humphreys, Olson and D'Ydewalle [(1995) Journal of Memory and Language, 34, 335–356] reported null phonemic masking effectswith homophone targets under conditionsdiscouraging reliance on phonology. Theyattributed these null effects to the absence ofreliance on phonology, concluding that relianceon phonology may be strategically controlled. Two studies using Verstaen et al.'s methodoccasionally replicate these null phonemicmasking effects, but challenge theirinterpretation. The emergence of null phonemicmasking effects was unrelated to the strategymanipulation. Conversely, evidence forphonology emerged in homophone errorsregardless of the strategy manipulation anddespite null phonemic masking effects. Ourfindings reflect an inherent instability in theperception of homophones. We demonstrate thatthis instability is directly due to reliance onphonology, rather than to its control. 相似文献

Klenowski (1995) identifies three aspects of ‘self‐assessment’. The present commentary examines these from the point of view of the development of learning‐to‐learn or ‘learning acumen’, which, it is proposed, comprises resilience, resourcefulness, reflectivity and responsibility. The minimal sense of self‐evaluation, in which students merely learn to monitor their performance in terms of externally specified criteria, may raise attainment without improving learning acumen, and may even damage it. What constitutes ‘good work’ is, in many domains, not reducible to the application of predetermined criteria. Self‐evaluation is essentially an intuitive process. Learning to see self‐evaluation as ‘marking one's own work’ by applying a checklist of criteria prevents the development of this intuitive ability. 相似文献
