The effect of subadditive pretraining on blocking: limits on generalization     

Wheeler DS  Beckers T  Miller RR 《Learning & behavior》2008,36(4):341-351

Recent evidence indicates that prior learning about a set of cues may determine how new cues are processed. If subjects are taught that two reliable predictors of an outcome do not summate when the cues are presented together (i.e., subadditive pretraining), the subjects will tend to show a less profound blocking effect when trained with different cues. Three experiments investigated the conditions necessary for subadditive pretraining to generalize to new cues. Experiment 1 demonstrated that subadditive pretraining is less effective in reducing blocking when it is experienced in a context other than that in which the blocking training is experienced. In Experiment 2, the effectiveness of subadditive pretraining waned with time. Experiment 3 showed that subadditive pretraining is more effective when the temporal characteristics of pretraining cues are similar to those of the cues used in blocking training. These results provide information concerning the conditions under which learning will generalize from one set of cues to another.  相似文献

The interplay between subjective abilities and subjective demands and its relationship with academic success. An application of the person–environment fit theory     

Carla Bohndick  Tom Rosman  Susanne Kohlmeyer  Heike M. Buhl 《Higher Education》2018,75(5):839-854

In this study, we draw on person–environment fit theory to analyze whether academic success is best explained by individual abilities subjectively exceeding situational demands or by abilities matching the demands. Moreover, we disentangled effects of perceived abilities and subjective person–environment (P-E) fit on academic success. All in all, 693 teacher education students participated in an online questionnaire. Students were asked to rate general requirements of their academic programs (e.g., self-discipline) on a 5-point scale in terms of (1) their own abilities and (2) the perceived relevance for their studies. P-E fit was determined by difference scores between abilities and relevance ratings. Academic success was assessed by grades, perceived performance, and study satisfaction. Data were analyzed through structural equation modeling and suggest that academic success is best explained by a match between abilities and demands. Moreover, all three criteria for academic success were more strongly related to subjective fit than to subjective abilities.  相似文献   

Reviews of research on the attitude–behavior relationship and their implications for future environmental education research     

Tom Marcinkowski  Alan Reid 《Environmental Education Research》2019,25(4):459-471

Since the early days of the field, attitude–behavior (A–B) relationships have received sustained attention in the evaluation and researching of environmental education (EE). This level of interest extends beyond the field’s scope though, in part due to a certain reliance on theoretical and empirical assertions which claim that attitudes serve as a strong precursor and/or predictor of behavior. In this paper, we consider reviews of studies on the A–B relationship in EE and other fields that routinely challenge such assumptions, leading to the questioning of corresponding foci and commitments for research, evaluation, practice, and development. With key findings from these studies hand, we highlight several insights that may be useful for dispelling some of the folklore about what matters in, and what can be argued with, A–B studies, if we are to develop the design, conduct, reporting, and critique of studies and practices of EE reliant on such relationships.  相似文献

Political conversations on Twitter in a disruptive scenario: The role of “party evangelists” during the 2015 Spanish general elections     

Tomás Baviera  Agnese Sampietro  Francisco J. García-Ull 《The Communication Review》2019,22(2):117-138

During election campaigns, candidates, parties, and media share their relevance on Twitter with a group of especially active users, aligned with a particular party. This paper introduces the profile of “party evangelists,” and explores the activity and effects these users had on the general political conversation during the 2015 Spanish general election. On that occasion, the electoral expectations were uncertain for the two major parties (PP and PSOE) because of the rise of two emerging parties that were disrupting the political status quo (Podemos and Ciudadanos). This was an ideal situation to assess the differences between the evangelists of established and emerging parties. The paper evaluates two aspects of the political conversation based on a corpus of 8.9 million tweets: the retweeting effectiveness, and the sentiment analysis of the overall conversation. We found that one of the emerging party’s evangelists dominated message dissemination to a much greater extent.  相似文献   

Effects of instructional objectives on learning and retention     

Tom E. Lawson 《Instructional Science》1974,3(1):1-21

A synthesis is presented of the various rationales which predict the facilitative influence of instructional objectives on learning and retention. Facets which are particularly relevant to the analysis of instructional objectives in learning situations include the dimensional character of attending behavior, the optimal degree of specificity to be incorporated in specifying instructional outcomes, effects of the placement or position of objectives during instruction, and a discussion of investigations concerned with an incidental or unspecified learning criterion. The conclusion is that, on each of these issues, various instructional conditions determine the efficacy of utilizing objectives to promote learning and retention.  相似文献   

The Actor–Partner Interdependence Model for Longitudinal Dyadic Data: An Implementation in the SEM Framework     

Fien Gistelinck  Tom Loeys 《Structural equation modeling》2019,26(3):329-347

In dyadic research, the actor–partner interdependence model (APIM) is widely used to model the effect of a predictor measured across dyad members on one’s own and one’s partner outcome. When such dyadic data are measured repeatedly over time, both the non-independence within couples and the non-independence over time need to be accounted for. In this paper, we present a longitudinal extension of the APIM, the L-APIM, that allows for both stable and time-varying sources of non-independence. Its implementation is readily available in multilevel software, such as proc mixed in SAS, but is lacking in the structural equation modeling (SEM) framework. We tackle the computational challenges associated with its SEM-implementation and propose a user-friendly free application for the L-APIM, which can be found at http://fgisteli.shinyapps.io/Shiny_LDD. As an illustration, we explore the actor and partner effects of positive relationship feelings on next day’s intimacy using 3-week diary data of 66 heterosexual couples.  相似文献   

Is outdoor education a discipline? Insights,gaps and future directions     

Tom G. Potter  Janet E. Dyment 《Journal of Adventure Education & Outdoor Learning》2016,16(2):146-159

This article critically explores ‘if’ and ‘how’ outdoor education (OE) is a discipline. This exploration stems from our experiences that OE is often undervalued, and from the belief that if OE is considered a discipline, then it would have greater acceptance, enhanced academic standing, importance, resourcing and prestige. Our analysis is rooted in a six-component discipline model which provides a framework for examining OE in relation to commonly understood attributes of stand-alone disciplines. In this article, we examine the final three components of the model. First, we explore the reference disciplines, such as education, psychology and sociology, which inform the OE field. Second, we examine the principles and practices of risk and reflection to chart how OE’s principles and practices have evolved over time. Finally, we report on the structures that support the OE field, such as academic programmes, journals, textbooks and curriculum. We draw on a range of historical and contemporary evidence to provocate on if and how OE is a discipline. We conclude the article with a discussion of the implications of these analyses juxtaposed alongside a discipline model and the challenges and opportunities that lie ahead for OE in the context of being a discipline.  相似文献   

Drawing Pedagogies in Higher Education: the Learning Impact of a Collaborative Cross‐disciplinary Drawing Course          下载免费PDF全文

Philippa Lyon  Patrick Letschka  Tom Ainsworth  Inam Haq 《The International Journal of Art & Design Education》2018,37(2):221-232

Drawing is taught in higher education across art and design but also, increasingly, in medical education, with a variety of aims and approaches. It is argued that there is a need, in both these disciplinary domains, to make more explicit the underpinning pedagogical approach to drawing and the impact that different approaches have on learning. The research described in this article focuses on an optional drawing course for undergraduate craft students and medical students. The course is run by the College of Arts and Humanities at a UK university and has a thematic focus on the human body. This qualitative case study sets out, in the context of selected theory about the teaching and learning of drawing, to explore what the learning impact of a particular collaborative model of teaching drawing was on a cross‐disciplinary student group. Findings included, with reference to Riley's framework of drawing pedagogies, that a range of philosophical and pedagogical ideas about drawing were blended from the teaching perspective in a way that enabled students from distinct disciplinary backgrounds to engage and learn. A shift was observed in students’ perceptions of drawing, with both sets of students questioning previously held assumptions about the use and value of drawing within their learning. Life drawing and anatomy laboratory drawing, in particular, provoked deep and challenging reflections about different cultural conceptions of the human body and the practice of collaborative drawing, with dialogic reflection, enabling insights to be developed into different disciplinary epistemologies.  相似文献
