Abstract

This study focused on the differences between experienced and inexperienced physical education teachers' approaches to planning, low inference indicators of teaching behavior during instruction, and global variables from the Beginning Teacher Evaluation Study. It was found experienced teachers asked many more questions before they began planning than did inexperienced teachers. Experienced teachers' plans reflected a concern about contingencies that might arise during instruction, whereas inexperienced teachers' plans did not. Interaction analysis and codings of student engagement showed marked differences between experienced and inexperienced teachers. Judging the qualities of experienced and inexperienced teachers also showed important differences. These sources of data are interrelated and give a vivid picture of how experienced and inexperienced teachers differ in accomplishment of instruction. The findings are discussed in terms of what they may mean for teacher development programs.  相似文献

Abstract

The contextual interference (CI) effect has been replicated many times since its first demonstration by Shea and Morgan (1979) in the motor learning domain (see Brady, 1998; Magill&;Hall, 1990). The CI effect is characterized by the observation that experiencing greater interference during acquisition is detrimental to immediate performance but enhances delayed performance as measured on retention or transfer tests. High CI is most often created by random practice in which the learning of multiple tasks occurs in a single training. In contrast, low CI is frequently created by using a blocked practice format in which all the practice trials of one task are completed before another task is introduced. One theoretical account that has been forwarded to account for the CI effect is labeled the action plan reconstruction hypothesis (Lee&;Magill, 1983, 1985). This position intimates that before a movement occurs an “action plan” must be prepared. In blocked practice, a previously prepared “action plan” is readily available from trial to trial, but it suffers from lack of attention on trials following initial retrieval from working memory. In random practice, however, each time a task must be executed a “reconstruction” of the action plan must be processed, because the interchange of information from trial to trial never allows the same information to remain in working memory for an extended amount of time. Presumably, the additional trial-to-trial preparation used by the random practice participant during practice results in a more resilient memory representation that better supports long-term recall efforts compared to their blocked practice counterparts.  相似文献

Testing a component model of reading comprehension in a randomized controlled trial, we evaluated the efficacy of 4 interventions that were designed to target components of language and metacognition that predict children’s reading comprehension: vocabulary, listening comprehension, comprehension of literate language, academic knowledge, and comprehension monitoring. Third- and 4th-graders with language skills falling below age expectations participated (N = 645). Overall, the component interventions were only somewhat effective in improving the targeted skills, compared to a business-as-usual control (g ranged from ?.14 to .33), and no main effects were significant after correcting for multiple comparisons. Effects did not generalize to other language skills or to students’ reading comprehension. Moreover, there were Child Characteristic × Treatment interaction effects. For example, the intervention designed to build sensorimotor mental representations was more effective for children with weaker vocabulary skills. Implications for component models of reading and interventions for children at risk of reading comprehension difficulties are discussed.  相似文献

This study investigates the effect of word study instruction on the orthographic knowledge of college students enrolled in a developmental reading course. Results revealed significantly greater improvement in orthographic knowledge in students who received word study instruction when compared with those in a control group, suggesting that the word study approach was effective for these students. Because of the influence of orthographic knowledge on spelling, writing and reading, additional research is merited to examine how word study intervention impacts the reading behaviours and academic achievement of college students enrolled in developmental education courses.  相似文献

This paper raises some questions about academic authorial honesty under the headings of Plagiarism (including self‐plagiarism), Theft, and Collusion. Compared with the medical sciences, the social sciences in general and education specifically, lag behind in terms of critical attention being paid to the problem of plagiarism, the peer review process and academic authorial ethics. The ubiquity of the Internet, the ever intensifying demand to publish or perish, and maybe, a general shift in perceptions of what constitutes ‘bad’ plagiarism and collusion which challenge traditional notions of what constitutes authorial honesty, mean that the time may be ripe for a consideration by academic writers and journal editors of how they regard and deal with the whole area. This paper makes an early contribution to the discussion.  相似文献

New York University's (NYU) Data Service Studio has recently launched the NYU Survey Service, whose ultimate aim is to support the development and administration of surveys of all types. For the Web-based component, the service utilizes a product called Qualtrics, which allows university affiliates to develop and administer Web-based surveys. This article describes the process by which NYU came to offer the service during a time when concerns abound about the ability of libraries to support and expand offerings while still meeting institutional imperatives such as robust data services. While many considerations went into the evaluation and ultimate conclusion to pilot the service, this article considers those most related to library collaborations, undergraduate instruction, data and information literacy, learning and research, and application administration and support.  相似文献
