ABSTRACT

This article proposes that Catherine Elgin and Nelson Goodman’s work on exemplification is relevant for discussions within moral philosophy and moral education. Generalizing Elgin and Goodman’s account of exemplification to also cover ethics, the article develops a two-factor account of moral exemplarity. According to this account, instantiation and expressivity are individually necessary and jointly sufficient conditions for someone or something to function as a moral exemplar. Applying this two-factor account of exemplarity to discussions within the philosophy of moral education the article then argues that it is the expressive aspect of moral exemplars, which explains and justifies the educational significance of such exemplars. The article concludes by discussing the similarities and differences between the expressivity account and the transparency criterion formulated by Michel Croce and Maria Silvia Vaccarezza in a recent paper.  相似文献

The acquisition of discriminated avoidance and classically conditioned leg flexions in dogs and of discriminated avoidance leg flexion in cats was examined via a two-phase model of conditioning. Classically conditioned Ss uniformly required two operators during Phase 2, with the limit of the CR operator being greater than that of the CR operator. Not all avoidance-trained Ss required two operators during Phase 2, but those who did also had a higher CR than CR operator limit. The CR operator limit was higher for avoidance than for classical training, while the change rate was greater for classical training. The avoidance behavior of cats paralleled that of the dogs. It was concluded that the data generally conformed to views of Hilgard and Marquis and, more recently, of Bolles, but were contrary to what would be expected from two-factor theory.  相似文献

In Experiment 1, four groups of subjects (n = 16 each) were exposed to the situational stimuli of a shuttlebox apparatus for 4 h. Subsequently, 200 two-way avoidance trials were administered (100/day) with either .3- or 1.6-mA shock and with either small or large reward (presence or absence of visual stimuli following the response). Avoidance performance was directly related to shock intensity on both days and to magnitude of reward on the 2nd day. In Experiment 2, four groups of subjects (n = 24 each) were given 4 h of exposure either to the situational stimuli of the shuttlebox or to a neutral box. Then, 10 two-way avoidance trials were given with 1.6-mA shock. Subsequently, subjects were allowed to escape from one of the shuttlebox compartments to an adjacent safe box. Following preexposure to situational stimuli, avoidance performance was superior whereas escape-from-fear performance was inferior. This latter finding demonstrated that less fear of situational cues was present during avoidance training in the preexposed condition. All of these results support the effective reinforcement theory, an extension of two-factor theory, which emphasizes the importance for avoidance learning of the amount of fear of situational cues present following a response.  相似文献

The roles of CS fear and of context fear in signaled two-way avoidance learning were examined in two experiments in which shock intensity was manipulated either between or within subjects. For each subject, two discrete CSs, a light and a white noise, were used. For between-subjects comparisons, both CSs were paired with the same shock intensity, weak or strong. Under this condition, in which fear of the CSs and the context was greater with strong than with weak shock, avoidance performance varied inversely with shock intensity. For within-subjects comparisons, the light was paired with strong shock and the white noise with weak shock, or vice versa. In this case, context fear was constant during presentation of each CS, and avoidance performance varied directly with shock intensity. Additionally, intertrial responding was directly related to the amount of context fear. These results support effective reinforcement theory, an extension of two-factor theory, which acknowledges the contribution to avoidance learning both of CS fear and of context fear. The interchangeable effectiveness of visual and auditory stimuli as CSs is discussed with regard to stimulus specificity in avoidance learning.  相似文献

Needs assessments are traditionally based on an optimals-actuals deficiency model that is utilized before instruction is implemented. However, in some cases an existing training program may be reassessed to determine what training needs still exist. These situations could benefit from an excess-based model, where the assessment effort is designed to identify instructional excesses as well as deficiencies. This article explains the theory and procedures for an innovative needs reassessment approach, the CODE system. The article also provides some empirical data on the potential value of the CODE process for decisions about the reallocation of instructional resources in existing training programs. Two exploratory studies were conducted that provide evidence of the validity of the CODE system: (a) a needs reassessment of a corporate training program, and (b) a medical training program reassessment.  相似文献

This article is a tribute to Graham Nuthall's contribution to classroom research from his early experimental studies through to his recent work on theory integration. It also explains the potential of the methodology, findings and theory building in our collaborative work to make a substantial positive difference for diverse students. The article explains the significance of, and need for, research linking learning to teaching processes (a scientific realist approach to putting ‘process’, socio-cultural context and theory building into a new process–product paradigm). Findings of student outcomes contrary to educational goals (for example, teaching designed to enhance appreciation of cultural differences triggering racist abuse) signal the importance of research that explains the impact of teaching on learner outcomes. The article also foreshadows the implications of the work that Graham and I did for teaching, teacher education, research and educational policy. The article concludes with Graham's view that the most important contribution his work would make, would be to initial teacher education.  相似文献

The inability to develop, strengthen, and access associations in memory that allow for the rapid and accurate retrieval of answers to basic addition problems is a distinguishing characteristic of a mathematics learning difficulty. The ‘two-factor theory of math fact learning’ (Robinson, Menchetti, & Torgesen, 2002) proposes that a weakness in semantic or phonological processing relating to number underlies such difficulty. The empirical support for this theory has been limited. In this study the basic addition performance of five adolescent students still reliant on counting was examined. A regression analysis of reaction times to counting trials revealed counting-speed to be an important factor in helping to explain why practice had not led to retrieval. The findings are discussed in terms of advancing the two-factor theory of math fact learning and implications for instruction are considered.  相似文献

This article examines a physics course for pre-service primary teachers in which physics, crafts and drama were taught together by connecting the standpoints of crafts and drama. The study was carried out by three university educators from these disciplines during an advanced optional course for student-teachers at the University of Helsinki in Finland. This article discusses the impact of the multidisciplinary teaching approach on the participants’ learning outcomes. First, the article explains the multidisciplinary teaching model, an educational energy game that the student-teachers designed as part of the course. Second, it describes the learning that emerged from the student-teachers’ learning process, including (1) learning skills, (2) new pedagogic thinking and (3) a change of attitude towards integrative teaching. Finally, the analysis shows the strength of sociocultural animation, which is traced through a path of becoming animated.  相似文献

Chronic school refusal has traditionally been classified under broad categories such as school phobia and truancy. However, the need for improved recognition and treatment of school refusal has heightened efforts to identify subtypes of school refusal behavior. Recent efforts have focused on functional subtypes of school refusal. This article purposes to extend recent efforts by showing that the three basic subtypes of anxiety, avoidance, and malingering are not only functional, but consistent with refusal characteristics, empirical evidence from factor analysis and clinical diagnosis over the past decade, and treatment approaches. Such extension is intended to aid practitioners in further understanding and using functional subtypes. © 2000 John Wiley & Sons, Inc.  相似文献

This article explains how communities of pastoral care work. It presents an empirically forged theory in action. We examined theoretical and empirical work across the targeted area of personalization for students. We also completed what Hallinger (2012) refers to as “exhaustive review” of the field of school improvement writ large. We treated the literature as qualitative data, inductively developing macro-level constructs, mid-level elements, and micro-level practices. We find that pastoral care for students has important effects on student learning. We conclude that the impact is mediated through two critical variables, institutional affiliation and student engagement.  相似文献

This study aims to validate a teacher-report measure of children's task-avoidant behavior, namely the Behavioral Strategy Rating Scale (BSRS), in a sample of 352 Finnish children. In each of the four waves from Kindergarten to Grade 2, teachers rated children's task-avoidant behavior using the BSRS, children completed reading and mathematics tests, and trained testers rated children's task-avoidant and social-dependent behavior after the test situation. Mothers also rated children's task-avoidant behavior in the last two waves. The results showed that a two-factor model including one factor representing task avoidance and one method factor accounting for wording effects among the negatively phrased items fitted the data best. The scale demonstrated strict measurement invariance across all four waves and satisfactory convergent and discriminant validity. Teacher-reported task avoidance was negatively associated with performance in reading and mathematics. The results suggest that the BSRS is a reliable, valid, and developmentally suitable instrument.  相似文献

This paper develops the thesis that the educational semiotic described by Cunningham offers an interesting perspective from which to view educational issues, but it offers little in the way of practical approaches to educational problems. After agreeing with Cunningham's argument that knowledge is constructed rather than received, the paper goes on to state three concerns about an educational semiotic: (a) The theory has the wrong architecture, (b) the theory is too powerful, and (c) the theory has no practical use. The paper closes with the observation that an educational semiotic must become more specific and it must provide empirical demonstrations of practical utility if it is to pose a challenge to currently prevailing theories.  相似文献

Achievement Goals and the Hierarchical Model of Achievement Motivation   总被引：13，自引：0，他引：13  
The achievement goal approach has attained prominence in the achievement motivation literature and has produced a valuable empirical yield. However, the precise nature of the achievement goal construct is in need of scrutiny, as is the issue of how achievement goals and their antecedents combine to produce competence-based self-regulation. In this article, we address these important conceptual issues in the context of the hierarchical model of achievement motivation. The approach–avoidance distinction, which has been an integral part of the achievement motivation literature since its inception, is highlighted throughout.  相似文献

Research on student veterans is in an infant state. As veterans continue to enroll in institutions of higher education, researchers must explore new ways of knowing student veterans. It is not enough to only describe and model this growing demographic, researchers must also have a tool for criticism and question. The next in an important tradition of emancipatory paradigms, this article suggests a critical theory built on current critical conversations but adapted for the unique characteristics of the student veteran. The article defines the need for a critical theory (Veteran Critical Theory), explains 11 tenets for this new theory, and discusses how these tenets could be used by administrators, faculty, student affairs professionals, and students in the higher education community.  相似文献

In current conceptualizations teacher sense of self-efficacy relates mainly to teaching tasks, in particular within the classroom context. This article offers a new conceptualization of teacher self-efficacy based on a broader work spectrum, comprising classroom and school-organizational contexts, with empirical evidence to support its validity. Participants were 555 teachers who served as respondents, filling out a self-report questionnaire. In a factor analysis of the scores, a two-factor structure emerged which consisted of teacher self-efficacy in the classroom and in the school-organizational domain. Each factor possessed professional tasks and inter-relation elements. The study suggests a new definition of teacher self-efficacy.  相似文献

Within policy circles, graduate employability remains a problem. It is often understood as an individual phenomenon, overlooking the influence of the organisation of higher education on the competition for graduate jobs. This article explores and compares how graduate employability is socially constructed within Great Britain and the Netherlands. It provides an analysis of both Dutch and British systems of higher education and explains how they shape the positional competition for graduate jobs. In addition it shows how perceptions of employability of final year university students relate to these two educational systems. The article is based on an empirical study on graduate employability in both countries using both micro analysis as well as contextual analysis. The article shows a fit between educational structure and employability strategies. The educational context shapes graduates' understandings and expectations of the competition for graduate jobs.  相似文献

Schwitzgebel (1999) has proposed an account of theories that can be used in deciding whether children's cognitive development is like theory change in science. In this article we outline an account of conceptual learning in terms of the conceptions that people hold, the status they award to their conceptions, and the conceptual ecology containing the criteria they use in determining status. A comparison of our account with Schwitzgebel's shows an equivalence between Schwitzgebel's subscribing and one component of status (fruitfulness), but no counterpart to another (plausibility). In addition, Schwitzgebel's account predicts that people possess an explanation-seeking curiosity that is associated with patterns of arousal and affect when anomalous phenomena are encountered. We present the results of empirical work that demonstrates that students do exhibit strong affective reactions to awareness of experimental anomalies and their resolution.  相似文献
