There have been many efforts to conceptualise literacy, both in terms of its essence and component parts, but it has proved difficult to define. This paper considers work that is undertaken with children and older learners with sensory needs in order to promote the early stages of literacy. Recent government initiatives aimed at fostering literacy development have caused teachers of children with sensory needs to re-examine their practice. The paper discusses early literacy as part of children's attempts to communicate and describes children with sensory needs engaging in a range of activities that are termed 'literacy' by those working with them. By taking into account these activities, the authors endeavour to throw light on the broader questions around concepts of literacy. 相似文献

This study investigated how emerging adult women perceive, role model, and wishfully identify with female television news personalities (TVNPs) in the contemporary climate of social media celebrity where a male-dominated newsroom persists. Participants (n = 138, M = 19.58 years) selected TVNPs and completed survey measures of exposure, personal work values, perceived TVNP work values, and wishful identification. Participants’ perceived extrinsic and intrinsic work values of TVNPs correlated with their own work values, extrinsically and intrinsically. Exposure to TVNPs predicted greater wishful identification. The discussion explores women’s perceptions of TVNPs as they formulate career plans. 相似文献

In Ontario, Canada, there is a demand for psychometrically robust screening tools capable of efficiently identifying students with specific learning disabilities (SLD), such as dyslexia. The present study investigated the ability of the Dyslexia Adult Screening Test (DAST) to discriminate between 117 post‐secondary students with carefully diagnosed SLDs and 121 comparison students. Results indicated that the DAST correctly identified only 74% of the students with SLDs as ‘highly at risk’ for dyslexia. Although employing the cutoff for ‘mildly at risk’ correctly identified 85% of the students with SLDs, this also increased the percentage of students with no major history of learning problems identified as ‘at risk’ for dyslexia from 16% to 26%. These findings suggest that the DAST in its present form is limited in its ability to screen for SLDs. Implications for future research are discussed. 相似文献

Parameters pertaining to information processing by human beings have, in the past, been determined by learning and memory experiments with nonsense syllables, number sequences, etc. However, in the real world we are concerned with the processing of meaningful information, not senselles texts. Therefore, the determination of subjective information directly from meaningful material becomes extremely important in the instruction-learning process.This study derives an equation for predicting the subjective textual information contained in a text of material written in the English language. Specifically, this investigation describes, by a mathematical equation, the relationship between the subjective information content of written textual material and the relative number of errors committed by a learner when asked to predict, letter by letter, the content of given textual material. This relationship shows that the subjective information of a given text for a specific learner is directly proportional to the number of wrongly guessed signs made by that learner. This is expressed mathematically by% MathType!MTEF!2!1!+- % feaafeart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn % hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr % 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq-Jc9 % vqaqpepm0xbba9pwe9Q8fs0-yqaqpepae9pg0FirpepeKkFr0xfr-x % fr-xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaamysaiabg2 % da9iaaiodacaGGUaGaaGymaiaabccacaWGfbaaaa!3B57! \[ I = 3.1{\rm{ }}E \] 0935 0212 VWhere: I = Information in bits E = Number of wrongly guessed signsThe application of Shannon's guessing procedure (1951) in this study permits the measurement of the subjective information of a given text for a specific learner. Unlike senseless texts, the subjective information of a meaningful text varies from learner to learner. Therefore, the derived equation permits the measurement of information in terms of a value that is dependent not only upon the inherent qualities of the subject matter, but also upon the internal state of the learner.The derived equation for the English language is then compared to an equation derived by Weltner (1967) for the German language and found to be remarkably similar.This work was, in part, supported by United States Air Force Contract F41609-71-C-0027 entitled Flying Training Research on Airborne and Ground Training Systems, and a research grant from Arizona State University. 相似文献

This paper explores selective literatures in the two fields of action learning and innovation, and seeks insights into the processes of, and connections between, innovation, engagement and implementation. We searched the action learning articles for references to innovation, beginning with the work of Revans, who highlights the innovation paradox, which becomes a key theme of this paper. We searched the very large innovation literature for references to innovation as a learning process and as a factor in organisational learning. The paper surveys the factors said to enable innovation, and briefly outlines some inhibitors, before considering Revans’ contribution to thinking about innovation. This is followed by a consideration of developments in action learning and innovation since Revans. The findings suggest that paradox theory is a useful way of thinking about innovation, conceived of as a practical problem involving resistances and frequent failures of implementation and adoption, and also propose action learning as a means of working with and addressing paradox. A limitation of this study is its lack of empirical data. Further research could usefully interrogate examples of innovation practices and ask such questions as to why innovation remains so elusive, and how innovative capacities and capabilities can be developed and enhanced. 相似文献

Factors that prevent learning in electrochemistry 总被引:1,自引:0,他引:1
Electrochemistry plays an important role in curricula, textbooks, and in everyday life. The purpose of the present study was to identify and understand secondary‐school students' problems in learning electrochemistry at an introductory chemistry level. The investigation covered four areas: (a) electrolytes, (b) transport of electric charges in electrolyte solutions, (c) the anode and the cathode, and (d) the minus and plus poles. Written tests were given to high‐school students in five cycles. The population from which random samples were drawn totalled 15,700 subjects. Students were asked to select the correct answers and to justify their choices. It was found that students based their reasoning on four alternative concepts: (a) During electrolysis, the electric current produces ions; (b) electrons migrate through the solution from one electrode to the other; (c) the cathode is always the minus pole, the anode the plus pole; and (d) the plus and minus poles carry charges. The results suggest a teaching strategy in which students first experience and learn about electrochemistry concepts. In the second step, appropriate concept terms are added, and students then are confronted with the alternative concepts described in this article. © 2006 Wiley Periodicals, Inc.
