The goals of this study were to investigate the timing and the mechanism by which two types of model-centered instruction
(MCI)—expert modeling (EM) and self-guided modeling (SGM)—might be made increasingly effective, efficient, and engaging for
learners with different levels of expertise. The 62 pre-service and in-service evaluators who participated in the study were
randomly assigned to one of these two types of MCI. The participants in the EM group were provided with the conceptual models
used by experts to solve ethical conflicts within program evaluation. The participants in SGM group received no guidance in
developing their own mental models. Regarding instructional effectiveness measures, there were no significant differences
between the two types of MCI. However, inexperienced learners in the EM group invested less instructional effort and time
than did those in the SGM group. In addition, inexperienced learners in the EM group also exhibited more engagement than did
those in the SGM group. Therefore, EM is likely to be the more appropriate instructional design for inexperienced learners.
Expert modeling required experienced learners to invest more mental effort, because if the conceptual model of the expert
was redundant, it required them to integrate the previous schema with resulting overload of their working memory. Regardless
of the types of MCI employed, the inexperienced participants showed significantly higher levels of attention and satisfaction
than did the experienced participants. 相似文献

The present exploratory investigation is an extension of a 1985 study that evaluated a Scholastic Aptitude Test preparation program involving black urban students. The present study was conducted to determine if there are identifiable characteristics of quantitative items associated with a susceptibility to coaching. Items showing p-value improvements of. 10 after coaching were compared with items not showing such improvements; comparisons were made in terms of the content, type. format, level of cognitive requirement, and position of the items. Items showing improvement were found across content areas, formats, and type. Findings are discussed in relation to the usefulness and improvement of well-designed supplemental instructional programs that have the potential to affect criterion performance in mathematics 相似文献

Two years after the end of a two-year intervention program intended to promote formal operational thinking, the achievement of students initially 12 years of age was tested by their results in British National examinations, taken at age 16. The intervention methodology was set within the context of science learning, so the difference between experimental and control classes was examined first in terms of their science results. The boys achieved an average of 40% more grades of C or above than the controls. This grade is the minimum criterion for higher education in Britain. The achievement was not found equally in all students: About 40% of the boys and 25% of the girls showed effect sizes of two standard deviations in relation to comparable controls, whereas the others did not differ from the controls. Both boys and girls showed significantly higher achievement in English than comparable controls, with an effect size about half that for science. The boys—but not the girls—also showed higher achievement in mathematics. It is argued that this evidence supports the interpretation that the students' increased science achievement was caused by increased general intellectual capacity, and not just by improved domain-specific skills. 相似文献

This article departures from the understanding of environmental sustainable education (ESE) as a political project that consists of dissonant and conflicting voices. The aim of the article is to understand how affection, i.e. bodily sensations, transform into political emotions in teaching and learning settings. The article offers a philosophical and empirically based model called the ‘political moment model’ for analyzing bodily anchored political emotions in teaching and learning of the political dimension. The model was developed in response to an empirical case study where the data were somewhat confusing. In order understand the empirical data, we used parts of Mouffe’s theory of the political and various scholars’ work on political emotions and placed these aspects in a pragmatist standpoint of experience, emotions and meaning making. The model helped to investigate students’ experiences of the political dimension in situations where they experienced affection, i.e. bodily sensation, and emotions in connection with reflections and discussions about how to handle public issues of sustainable development. The article ends with a theoretical discussion of the findings in order to understand the political dimension in teaching and learning activities and to discern possible directions for future research on political moments in ESE. 相似文献
