The notion of general cognitive ability (or ‘intelligence’) is explored and why the time might now be ripe for educators to re-consider the power offered by a general intellectual capacity which is itself amenable to educational influence. We review existing knowledge concerning general intelligence, including the cohabitation of general and special abilities, cognitive modules, development, and evidence for plasticity of the general processor. We examine why this knowledge is generally absent from educational practice and present a number of models that attempt to synthesise the main aspects of current psychological theories. We explore how the models might be used in educational applications and look at examples of effective cognitive stimulation considering both practicalities and theoretical notions of what in our cognitive models is affected by stimulation. We discuss finally the possible political, cultural and social barriers to the inclusion of general ability as central to educational aims. 相似文献

This Monograph aims to contribute to the information processing, the differential, and the developmental modeling of the mind, and to work these into an integrated theory. Toward this aim, a longitudinal study is presented that investigates the relations between processing efficiency, working memory, and problem solving from the age of 8 years to to the age of 16 years. The study involved 113 participants, about equally drawn among 8-, 10-, 12-, and 14-year-olds at the first testing; these participants were tested two more times spaced one year apart. Participants were tested with a large array of tasks addressed to processing efficiency (i.e., speed of processing and inhibition), working memory (in terms of Baddeley's model, phonological storage, visual storage, and the central executive of working memory), and problem solving (quantitative, spatial, and verbal reasoning). Confirmatory factor analysis validated the presence of each of the above dimensions and indicated that they are organized in a three-stratum hierarchy. The first stratum includes all of the individual dimensions mentioned above. These dimensions are organized, at the second stratum, in three constructs: processing efficiency, working memory, and problem solving. Finally, all second-order constructs are strongly related to a third-order general factor. This structure was stable in time. Structural equation modeling indicated that the various dimensions are interrelated in a cascade fashion so that more fundamental dimensions are part of more complex dimensions. That is, speed of processing is the most important aspect of processing efficiency, and it perfectly relates to the condition of inhibition, indicating that the more efficient one is in stimulus encoding and identification, the more efficient one is in inhibition. In turn, processing efficiency is strongly related to the condition of executive processes in working memory, which, in turn, is related to the condition of the two modality-specific stores (phonological and visual). Finally, problem solving is related to processing efficiency and working memory, the central executive in particular. All dimensions appear to change systematically with time. Growth modeling suggested that there are significant individual differences in attainment in each of the three aspects of the mind investigated. Moreover, each of the three aspects of the mind as well as their interrelations change differently during development. Mixture growth modeling suggested that there are four types of developing persons, each defined by a different combination of performance in these aspects of the mind. Some types are more efficient and stable developers than others. These analyses indicated that processing efficiency is a factor closely associated with developmental differences in problem solving, whereas working memory is associated with individual differences. Modeling by logistic equations uncovered the rates and form of change in the various dimensions and their reciprocal interactions during development. These findings are discussed from the point of view of information processing, differential, and developmental models of thinking, and an integrative model is proposed. 相似文献

Introducing a Teacher Evaluation System Based on Teacher Effectiveness Research: An Investigation of Stakeholders’ Perceptions 总被引：1，自引：0，他引：1
Leonidas Kyriakides Demetris Demetriou 《Educational Assessment, Evaluation and Accountability》2007,20(1-2):43-64
Teacher Effectiveness Research (TER) could be a foundation upon which a valid teacher evaluation system could be built. However, even a technically exceptional evaluation system may be doomed to fail if the political dynamics that influence its implementation are not examined. This study examines the extent to which a proposed teacher evaluation system based on TER is possible to gain acceptance from the main stakeholders of the Cypriot educational system. The extent to which stakeholders’ reactions to the proposed system are associated with their personal interests and concerns is also investigated. Both groups recognized that TER could be a foundation upon which a valid teacher evaluation system could be built but were critical of suggestions that might reduce their professional power. In order to reach consensus, policy makers should establish procedures to ensure a clear understanding among stakeholders of both the theoretical assumptions of the proposed system and the type of concerns that stakeholders might have against change. 相似文献

The development of two observational tools for assessing metacognition and self-regulated learning in young children 总被引：1，自引：1，他引：0

This paper reports on observational approaches developed within a UK study to the identification and assessment of metacognition
and self-regulation in young children in the 3–5 year age range. It is argued that the development of observational tools,
although containing methodological difficulties, allows us to make more valid assessments of children’s metacognitive and
self-regulatory abilities in this age group. The analysis of 582 metacognitive or self-regulatory videotaped ‘events’ is described,
including the development of a coding framework identifying verbal and non-verbal indicators. The construction of an observational
instrument, the Children’s Independent Learning Development (CHILD 3–5) checklist, is also reported together with evidence
of the reliability with which it can be used by classroom teachers and early indications of its external validity as a measure
of metacognition and self-regulation in young children. Given the educational significance of children’s development of metacognitive
and self-regulatory skills, it is argued that the development of such an instrument is potentially highly beneficial. The
establishment of the metacognitive and self-regulatory capabilities of young children by means of the kinds of observational
tools developed within this study also has clear and significant implications for models and theories of metacognition and
self-regulation. The paper concludes with a discussion of these implications.

The reactions of students to forensic dissection encompass psychologico-emotional and physical components. This exploratory study aimed to determine risk factors for students' adverse physical and psychological reactions to forensic dissection. All sixth-year medical students (n = 304) attending the compulsory practical course in forensic medicine in the 2005-2006 academic year were asked to complete a questionnaire at the conclusion of the five-day course. The questionnaire surveyed physical and psychological reactions (outcomes) and 47 student traits, beliefs, and behaviors (risk factors) that might predispose to adverse reactions. Multivariate ordinal logistic regression yielded five independent risk factors for negative psychological reactions: female gender, stereotypic beliefs about forensic pathologists, a less cognitive and more emotional frame of mind relative to forensic dissection, more passive coping strategies, and greater fear of death. The sole independent risk factor for physical symptoms was a less cognitive/more emotional approach to dissection. Students' reactions to forensic dissection integrate a host of inherent and dissection-related risk factors, and future interventions to improve this aspect of medical education will need to take into account the complexities underlying students' experiences with dissection. 相似文献

In Greece, there is no officially organized training in clinical chemistry for scientists. The Greek Society of Clinical Chemistry-Clinical Biochemistry decided to organize an intensive educational program of 18 seminars on clinical chemistry content as it is described in the EC4 Syllabus. The duration of each seminar was about 6 hours and consisted of 6 to 9 lectures. At the end of each seminar there was a voluntary written examination, comprised of 24 multiple choice questions. Successful completion of the Educational program was leading to a Certificate of Competence. Two cycles of the 18 seminars were performed: 1st cycle from October 2003 to December 2005 and 2nd cycle from March 2005 to October 2007. One hundred eighty nine colleagues was the mean attendance per seminar for the seminars of the 1st cycle and 38 colleagues for the seminars of the 2nd cycle. The mean participation to the examination for each seminar was almost 80% for the 1st cycle and 68% for the 2nd cycle. More than 80% of the participants performed Good or Very good in the examination in both cycles. It is estimated that more than 40% of the scientists who practice Clinical Chemistry in Greece, participated to this educational activity. This program is now provided as an e-learning application, and it is open for all scientists who want to follow the discipline of clinical chemistry. 相似文献

Although lots of studies have investigated collaborative knowledge construction in online courses, the factors influencing this process are yet to be fully determined. This study provides quantitative and qualitative types of evidence on how (naturally emerged) student facilitation and quality of initial postings influence collaborative knowledge construction in online discussions. We analyzed the discourse of nine student groups (N = 34) working on a case problem in an online discussion forum. We found that student facilitation was an important contributor to the process. In contrast, the contribution of low-quality postings in early stages of the discussion can jeopardize the process. This work is an attempt to address quality in online learning by helping instructors decide on encouraging student facilitation in online discussions as well as structuring and carefully monitoring the content of initial discussion postings. 相似文献

This paper investigates the impact of three different approaches to establishing School Self Evaluation (SSE) mechanisms upon student achievement. Using group randomisation, four groups of schools were created. Different types of support were provided to the first three groups of schools in order to help them establish SSE mechanisms, whereas no SSE mechanism was established in any of the schools of the fourth group. In the first group, school stakeholders were offered the opportunity to develop their own SSE mechanisms and design their own improvement strategies. The second group followed the same process in designing SSE mechanisms as the first, but before introducing this approach support was offered to the stakeholders in order to address and reduce their concerns about SSE. The third group was asked to develop SSE mechanisms and take decisions for their improvement strategies which were in line with the knowledge base of educational effectiveness research. All three experimental groups had better results than the control group, but the impact of the third approach on student achievement was higher than the impact of the other two approaches to SSE. Implications for research on SSE are drawn. 相似文献
