Successive reversals of a discriminated preference for signaled tailshock     

Ralph R. Miller  David Daniel  Alvin M. Berk 《Learning & behavior》1974,2(4):271-274

Three rats received unmodifiable tailshock at random intervals in a shuttlebox. In a continuous-choice situation, Ss could choose between an auditory signal immediately preceding or immediately following the tailshock. Over repeated daily 3-h sessions, each S acquired a spatial discrimination indicating a strong preference for the signal preceding tailshock. This preference continued undiminished through two successive reversals of the position associated with signaled shock. This demonstration precludes explanations of the preference-for-signaled-shock phenomenon based upon primary reinforcement value or acquired value of the signal, position preferences, and overt modification of the aversiveness of the reinforcer through such means as postural adjustments. An explanation of recent failures to obtain the preference-for-signaled-shock effect is offered.  相似文献

Depth of processing and the quality of learning outcomes     

David Watkins 《Instructional Science》1983,12(1):49-58

Problems associated with earlier research on the relationship between depth of processing and quality of learning outcomes are first discussed. Then I present an interview study with 60 second year tertiary students which supports the hypothesis that depth of processing is related to the quality of learning outcomes.  相似文献   

The effects of isolation and handling on reactivity to footshock and tactile dorsal stimulation     

Richard J. Viken  Danny L. Moore  John F. Knutson  David J. Fordyce 《Learning & behavior》1982,10(2):135-140

The effects of isolation and handling on the reactivity of rats to two tactile stimuli were assessed in two experiments. In the first experiment, reactivity to more intense footshock was increased in rats raised in isolation but was not affected by handling by an experimenter. In the second experiment, increased reactivity to airpuff stimuli presented to the dorsal surface of isolation-reared rats was reduced by handling. The data suggest that the effects of handling on shock-motivated behaviors are not due to altered reactivity to shock and that the effect of housing or handling must be considered in behavioral tests in which reactivity to tactile stimulation might play a role as dependent or independent variables.  相似文献   

Secondary science teachers' knowledge base when teaching science courses in and out of their area of certification     

Linda R. Sanders  Hilda Borko  J. David Lockard 《科学教学研究杂志》1993,30(7):723-736

This study examined the similarities and differences in experienced secondary science teachers' planning, teaching, and reflecting on their teaching, when teaching in their science area of certification and when teaching in another science area. The study also focused on the influence of these teachers' content knowledge, pedagogical knowledge, and pedagogical content knowledge on their planning, teaching, and reflecting. Experienced teachers were observed and interviewed while teaching classes in their science area of certification, and in another science area they were teaching for the first or second time. Both similarities and differences in teaching were found in the two areas for all three teachers. For example, their planning and postlesson reflections were similar in both areas. In the interactive phase of teaching more differences were observed. Many aspects of their teaching resembled that of expert teachers in other studies. In the unfamiliar science area, the teachers sometimes acted like novice teachers. However, they were able to draw upon their pedagogical knowledge to provide a framework for their teaching in both science areas. Their wealth of pedagogical knowledge, and pedagogical content knowledge for general science topics, seemed to sustain them in whatever content they were teaching. Recommendations for further study and implications for teacher education are discussed.  相似文献

The engagement agenda,multimedia learning and the use of images in higher education lecturing: or,how to end death by PowerPoint     

David Roberts 《Journal of Further & Higher Education》2018,42(7):969-985

This article is concerned with student engagement and understanding in large group teaching in Higher Education (HE). Specifically, it is concerned with the application of Multimedia Learning (MML) methods in Politics, History, International Relations, Sociology, Social Work, and Business and Economics teaching that privilege the use of images to complement text in lecture presentations. This ‘visual’ method, it is claimed in the literature, generates engagement and understanding better than text alone. This article develops, applies and empirically tests with students, MML methods across a range of Higher Education disciplines over three years. The research deploys Participatory Action Research (PAR) methods engaging students as active agents of investigation and change. It finds evidence to support the hypothesis that apposite images combined with reduced text increases students’ engagement and understanding with academic content, but that much formal research needs to expand on the range of demographics tested.  相似文献
