This article reports on how a small group of New York City adolescents interpreted audio‐visual expressions that were created by youth participating in the international VideoCulture Project. The New York City youth looked for explicit messages in the youth‐produced video films, but also appreciated features of content and form that prompted their curiosity about the youth producers’ intent, as well as experience of everyday life. This study suggests how American culture has influenced these youth's sensibilities about audio‐visual communication, and discusses the value and problems of engaging youth in projects of this nature  相似文献

Over the past decade, repeated calls have been made to incorporate more active teaching and learning in undergraduate biology courses. The emphasis on inquiry-based teaching is especially important in laboratory courses, as these are the courses in which students are applying the process of science. To determine the current state of research on inquiry-based teaching in undergraduate biology laboratory courses, we reviewed the recent published literature on inquiry-based exercises. The majority of studies in our data set were in the subdisciplines of biochemistry, cell biology, developmental biology, genetics, and molecular biology. In addition, most exercises were guided inquiry, rather than open ended or research based. Almost 75% of the studies included assessment data, with two-thirds of these studies including multiple types of assessment data. However, few exercises were assessed in multiple courses or at multiple institutions. Furthermore, assessments were rarely based on published instruments. Although the results of the studies in our data set show a positive effect of inquiry-based teaching in biology laboratory courses on student learning gains, research that uses the same instrument across a range of courses and institutions is needed to determine whether these results can be generalized.  相似文献

A dance programme for a class of students with special needs was evaluated using a multiple baseline across behaviours design where the behaviours were movements representing aspects of the elements of dance: Space, Body Awareness, Relationships, Levels, Effort, Speed and Shape. Observational data showed that the instructional dance programme was successful in extending the variety of movements performed by the students and that the observational methodology designed for the study was a useful strategy for evaluating teaching in dance.  相似文献

Abstract

The claim that students should determine their own curricula is examined. If granted, primacy would be given to the autonomy and self‐ascribed interests of the students. The case for student autonomy is discussed in the context of the theory of philosophical anarchism. The anarchist dichotomy of autonomy and authority is criticised. A brief examination of Kant's account of autonomy leads to a rejection of the strong individualism that characterises that dichotomy. It is argued that the curriculum should be the outcome of the shared autonomy of students and teachers; such would serve the interests of students by maximising the autonomy of all. The curriculum would meet the interests of all students, but would not, indeed could not, represent the self‐ascribed interests of each individual.  相似文献

This paper describes Dragoon, a simple intelligent tutoring system which teaches the construction of models of dynamic systems. Modelling is one of seven practices dictated in two new sets of educational standards in the U.S.A., and Dragoon is one of the first systems for teaching model construction for dynamic systems. Dragoon can be classified as a step-based tutoring system that uses example-tracing, an explicit pedagogical policy and an open learner model. Dragoon can also be used for computer-supported collaborative learning, and provides tools for classroom orchestration. This paper describes the features, user interfaces, and architecture of Dragoon; compares and contrasts Dragoon with other intelligent tutoring systems; and presents a brief overview of formative and summative evaluations of Dragoon in both high school and college classes. Of four summative evaluations, three found that students who used Dragoon learned more about the target system than students who did equivalent work without Dragoon.  相似文献

Abstract

Pedometers have been identified as a tool for health professionals to promote physical activity. This study, which aimed to evaluate the effectiveness of wearing a pedometer on general practitioners' attitudes to promoting physical activity, was a pragmatic, multi-centred, randomized controlled trial within a primary care trust in England. The participants were 102 general practitioners (GPs). Eighty-five (48 males, 37 females) of the GPs completed pre and post questionnaires, 43 of whom were in the intervention group. Statistical analysis revealed no significant changes between the control and intervention groups for attitude to engage in physical activity (t 83 = 1.13, CI ?0.362 to 0.099) or attitude to promote physical activity in their patients (t 83 = 1.7, CI ?0.593 to 0.045). A higher volume of walking was significantly correlated with a more positive attitude to engage in physical activity (r = 0.58, P < 0.01) but not with a more positive attitude to promoting physical activity. Wearing a pedometer had no significant effect on GPs' attitudes to engaging in physical activity or promoting physical activity in their patients.  相似文献

Black and White students who enrolled in college by age 20 were selected from a national probability sample, in order to estimate the prevalence of having children and the effect of having a child on probability of graduation with a bachelors degree. Black students reported significantly higher rates of having children than White students, but rates for Black students at historically Black universities were similar to those of Black students at predominantly White universities. After controlling for family background, achievement, and other student characteristics, having a child within 5 years of starting college generally reduced the probability of graduating with a bachelors degree for Black women and White women and men. The independent effect of attending a historically Black college was significantly positive for Black women but not statistically significant for Black men.  相似文献
