Blocking of conditioned suppression with 1 or 10 compound trials     

Julian L. Azorlosa  George A. Cicala 《Learning & behavior》1986,14(2):163-167

It is generally agreed that the Kamin blocking effect provides a differential test of the model of classical conditioning proposed by Rescorla and Wagner (1972), on the one hand, and the models proposed by Mackintosh (1975) and Pearce and Hall (1980), on the other. Specifically, if the blocking effect occurs with 1 compound trial, Rescorla and Wagner are supported. Experiment 1 showed that prior training with one element of a simultaneous compound stimulus prevented the added element from becoming conditioned with 10 compound trials when compared with a nonpretrained (Kamin) control. A pseudoconditioning control, which received no compound training, showed substantial suppression only on the first trial. A contextual conditioning control, which received unsignaled shock prior to compound training, was suppressed, suggesting a failure of conditioning to contextual cues. Experiment 2 demonstrated 1-compound-trial blocking using a simultaneous presentation of the compound elements. The importance of this support for the Rescorla-Wagner model is discussed in the light of other supportive studies and those which support alternative models of classical conditioning.  相似文献   

Notes on Classroom Practice and the Ownership and Use of Personal Computers Amongst Egyptian Science and Mathematics Teachers     

Martin Monk  Julian Swain  Mary Ghrist  Wendy Riddle 《Education and Information Technologies》2003,8(1):83-95

This paper reports a study of the acquisition and use of personal computers by Egyptian science and mathematics teachers. Self-report data was collected from the same teachers on how they had changed their classroom activities and professional practice since their return to Egypt following a twelve-week in-service course in the United Kingdom. The data from this sample of teachers is compared with that from a second sample, who also attended the same in-service programme, but did not report the purchase of a personal computer. Analysis indicates that the Egyptian teachers with personal computers have tended to concentrate on improving the quality of current practice, through better preparation and student testing, rather than introducing major, paradigmatic, changes to their teaching.  相似文献   

The Real-Time Case Method: Description and Analysis of the First Implementation     

Clare Kilbane  James Theroux  Julian Sulej  Barry Bisson  David Hay  Dennis Boyer 《Innovative Higher Education》2004,29(2):121-135

This article describes the first implementation of the Real-time Case Method (RTCM)—a new instructional practice that makes use of various technologies to create a new type of case study. Data obtained from five instructors at four business schools in the U.S. and Canada were analyzed using analytic induction. Analysis suggests RTCM was successfully implemented at both the graduate and undergraduate levels, in traditional face-to-face as well as online learning environments, with students of varying levels of experience and backgrounds, and by instructors with differing professional backgrounds and teaching styles. The instructors were highly satisfied with the method. They observed that students were engaged by RTCM, that it motivated them to work harder and longer on assignments, and that it allowed them to have experiences that were qualitatively different from those available from textbooks and traditional cases.  相似文献   

A guide to establishing hybrid learning courses: Employing information technology to create a new learning experience, and a case study   总被引：2，自引：1，他引：2  

Kamolbhan Olapiriyakul  Julian M. Scher   《The Internet and Higher Education》2006,9(4):287-301

Hybrid learning, or blended learning, has become an interesting learning delivery method in recent years. Many universities have sought to develop their own hybrid learning courses as another option for students and instructors who prefer to replace some portion of traditional face-to-face meeting time with online instruction. This paper provides some pragmatic guidance for establishing hybrid learning courses in universities. The authors focus on the use of information technology, as well as the development and the design of the course content. The paper also illustrates a case study of hybrid learning courses at NJIT. The research results showed no significant difference between the performance of the students who took a course in hybrid mode versus the performance of those who took the identical course in distance learning mode. Some positive feedback in terms of perceived benefit from the hybrid course instruction and course materials was obtained from the students. The student learning styles were also investigated. The results demonstrated that the majority of students who participated in the hybrid learning course are active/sensing/sequential/visual learners. Most of them preferred visual presentations to verbal explanations. The research results also revealed the difference between learning styles of students with high performance, and those with low performance.  相似文献   

Mind the Gap: Why do people act environmentally and what are the barriers to pro-environmental behavior?   总被引：3，自引：6，他引：3  

Anja Kollmuss  Julian Agyeman 《Environmental Education Research》2002,8(3):239-260

Numerous theoretical frameworks have been developed to explain the gap between the possession of environmental knowledge and environmental awareness, and displaying pro-environmental behavior. Although many hundreds of studies have been undertaken, no definitive explanation has yet been found. Our article describes a few of the most influential and commonly used analytical frameworks: early US linear progression models; altruism, empathy and prosocial behavior models; and finally, sociological models. All of the models we discuss (and many of the ones we do not such as economic models, psychological models that look at behavior in general, social marketing models and that have become known as deliberative and inclusionary processes or procedures (DIPS)) have some validity in certain circumstances. This indicates that the question of what shapes pro-environmental behavior is such a complex one that it cannot be visualized through one single framework or diagram. We then analyze the factors that have been found to have some influence, positive or negative, on pro-environmental behavior such as demographic factors, external factors (e.g. institutional, economic, social and cultural) and internal factors (e.g. motivation, pro-environmental knowledge, awareness, values, attitudes, emotion, locus of control, responsibilities and priorities). Although we point out that developing a model that tries to incorporate all factors might neither be feasible nor useful, we feel that it can help illuminate this complex field. Accordingly, we propose our own model based on the work of Fliegenschnee and Schelakovsky (1998) who were influenced by Fietkau and Kessel (1981).  相似文献

Encouraging the development of higher-level study skills using an experiential learning framework     

Mark Groves  Kathryn Leflay  Julian Smith  Belinda Bowd  Alison Barber 《Teaching in Higher Education》2013,18(5):545-556

Teachers have only recently considered how study skills support in higher education (HE) can be delivered in a way that encourages experiential learning. This paper aims to substantiate, or otherwise, the idea that a carefully developed initiative can encourage the experiential learning of study skills. In addition, it considers whether such an approach might also allow student access to some of the higher-level study skills required for successful university study. Focus group data were used to evaluate a module delivered to sports students at a post-1992 university in the UK. This data suggested that the module facilitated learning in each stage of Kolb's experiential learning cycle. Moreover, there was evidence that the module encouraged students to undertake an ‘epistemological shift’ in which they moved from seeing knowledge as a set of uncontested facts to seeing it as something that they are expected to question and contribute to themselves.  相似文献

Progressive Education,After-School Programs and their Impact on the Lives of African American Males: An Introduction     

Carter Julian Savage 《Peabody Journal of Education》2013,88(4):407-420

This edition of the Peabody Journal of Education analyzes the historical and contemporary role of after-school programs in the development of African American males. In this introduction, the author places after-school programs within an historical context of progressivism, progressive education and social change in 19th-century America. As these new ideas of children and childhood were conceptualized, four significant social changes in America—industrialization, urbanization, immigration, and an “American reformation”—sparked the implementation of remedies for social ills within urban settings. This article suggests that the early 20th-century focus on after-school programs for African Americans were the results of lessons learned from early “remedies” targeting “new” immigrants. Moreover, the later desire to assist African American youth through these national and local youth development organizations was spurred by the rapid migration of African Americans to the urban northeast and Midwest during the first quarter of the 20th century. Moreover, the failed efforts of African Americans to acquire decent housing, the resulting crowding into segregated neighborhoods, and the deteriorating conditions of these urban, African American neighborhoods drew the attention of progressives, both African American and White, who were knowledgeable of and/or serving immigrant communities to provide similar services in urban, African American communities. ¹ This statement does not suggest that the African American community lacked interest in the development of organizations to serve their youth; however, these conditions did spark the interest of the larger community to act.

The Integrating and Segregating Effects of School Choice   总被引：1，自引：1，他引：0

We evaluate the integrating and segregating effects of three distinct school choice programs in San Diego. We go beyond the traditional question of racial integration and examine the integration of students by test scores, parental education levels, and language status. In addition to measuring the net integrative effects of school choice, we also examine the underlying motives behind student participation in school choice programs and the limiting influence of supply-side constraints. Two of the programs that we consider are rooted in 1970s integration-based reforms that provide public transportation for program participants. The third program is a state-mandated, open-enrollment program that requires participants to find their own transportation to and from their choice schools. We find that the two programs with underlying integrative objectives do indeed integrate the district, but the open-enrollment program segregates the district along most dimensions. Provision of busing and geographic preferences appear to be important factors in promoting integration.  相似文献
