This paper describes the use of learning-hierarchy analysis in studies of expertise. A hierarchical analysis was carried out on expertise in language-arts teacher planning for a short story. The resulting hierarchy depicted a complex pattern of prerequisite intellectual skills integrating knowledge of students, reading difficulty, strategies/activities, and the author (Stephen Crane). Of particular interest was that each branch of the hierarchy included “fuzzy sets,” that is, complex conceptual knowledge that experts were usually unable to explain. All elements in the hierarchy were capabilities learned from experience as opposed to direct instruction. It was recommended that advice-strategies developed from hierarchical analysis could be used to facilitate the development of expertise. These strategies do not teach expertise directly but encourage the learner to glean the most from task-relevant experience.  相似文献

This article discusses an empirical study on the use of history as a goal. A historical module is designed and implemented in a Danish upper secondary class in order to study the students’ capabilities at engaging in meta-issue discussions and reflections on mathematics and its history. Based on videos of the implementation, students’ hand-in essay assignments, questionnaires, and follow-up interviews, the conditions, sense, and extent to which the students are able to perform such discussions and reflections are analyzed using a described theoretical framework.  相似文献

The purpose of this study was to further examine the factor structure of the Huber Inventory of Trainee Self‐Efficacy (HITS), a measure of school psychology trainee self‐efficacy. Lockwood et al. (2017, Psychol. Sch., Vol. 54, pp. 655–670) extant data set, collected from 520 school psychology trainees, was utilized. Four measurement models were examined for model fit and factor loadings. Of the four models, a bifactor model with a single latent general self‐efficacy (GSE) and latent domain‐specific factors (i.e., Multidimensional Assessment Skills, Counseling Skills, Professional Interpersonal Skills, and Research Skills) was the most parsimonious. However, standardized loadings indicated that all practice‐related items loaded more significantly onto GSE than their domain‐specific factors, indicating the utility of GSE for practice‐related skills. Of note, the Research Skills factor displayed greater domain‐specific loadings than general loadings. These findings suggest that GSE may be the best indicator of trainee self‐efficacy, though a two‐factor model that represents practical skills versus research skills may also be appropriate. Additionally, reliability scores indicate that subscale interpretation may also be reasonable. Limitations, implications for trainers of school psychologists, and for future research directions are discussed.  相似文献

Business students taking data mining classes are often introduced to artificial neural networks (ANN) through point and click navigation exercises in application software. Even if correct outcomes are obtained, students frequently do not obtain a thorough understanding of ANN processes. This spreadsheet model was created to illuminate the roles of the following ANN parameters: weights, learning rates, threshold functions, and transformation functions. The spreadsheet ANN model project is given early in the semester, just after ANN is introduced. Students can see effects of ANN parameters as they make changes to spreadsheet model inputs, greatly enhancing discussion of ANN processes. After working with the spreadsheet model, students have expressed an appreciation for decisions based on patterns of historic data, and they like the ability to peek “behind the curtain” at processes of predictive software packages.  相似文献

By maintaining that moral functioning depends upon four components (sensitivity, judgment, motivation, and character), the Neo-Kohlbergian account of moral functioning allows for uneven moral development within individuals. However, I argue that the four-component model does not go far enough. I offer a more accurate account of moral functioning and uneven moral development. My proposal retains the account of sensitivity, divides the judgment component into a theorizing component and a reasoning component, and eliminates the motivation and character components.  相似文献

Knowledge management (KM) in the U.S. Navy is championed as a strategic initiative to improve shipboard maintenance and troubleshooting at a distance. The approach requires capturing, coordinating, and distributing domain expertise in electronics and computer engineering via advanced information and communication technologies. Coordination must be achieved to ensure ship readiness. A potential challenge for human performance technologists is to develop robust theoretical frameworks to analyze and explain existing practice within this context. To illustrate, we present the case of U.S. naval sailors and civilian subject‐matter experts (SMEs) collaboratively troubleshooting complex shipboard radar systems across ship and shore. Adapting perspectives from organizational theory, information science, and educational psychology, we conduct a multi‐level analysis of the context of distributed knowledge and work. Findings suggest that regulative and normative restrictions, boundary spanners and objects, and disruption of coordination across system components influence practice substantively. Implications for research and practice, including a readdressing of the existing cannon of analytical frameworks are offered.  相似文献
