This study explores the evolution, diffusion and application of audience research in public television from its origins through the 1970s, the formative period for the system. Shifts in funding structures for public TV and the rise of cable and satellite competition are reflected in the changing practice of such research.  相似文献

This paper describes the model of internationally supported self-study developed at the Kathmandu International Study Centre in Nepal. The Centre aims to provide for the varied home country needs of the secondary aged expatriate children resident in Nepal through a balanced programme of group tutorials and self-study activities. The various facets of the model and their rationale are discussed under the headings of Structure, Physical environment and People. Based upon the experience gained, recommendations for practice are made. The creation of an environment conducive to learning is discussed, with reference to the contribution made to this environment by the physical surroundings, tutors, and the students themselves.  相似文献

This article reports the results of a positive youth development (PYD) intervention for adolescents in alternative high schools (209 African American and Hispanic American adolescents, aged 14–18; 118 females and 91 males). The intervention was guided by a self‐transformative model of PYD (Eichas, Meca, Montgomery, & Kurtines, 2014). This model proposes that the actions youth take to define themselves function as active ingredients in positive development over the life course. Consistent with the self‐transformative model, results provided support for direct or mediated intervention effects on the self‐transformative processes of self‐construction and self‐discovery, life goal development, identity synthesis, and internalizing problems. The findings illustrate the utility of using a self‐transformative approach to PYD in work with marginalized youth populations.  相似文献

Concept inventories, consisting of multiple-choice questions designed around common student misconceptions, are designed to reveal student thinking. However, students often have complex, heterogeneous ideas about scientific concepts. Constructed-response assessments, in which students must create their own answer, may better reveal students' thinking, but are time- and resource-intensive to evaluate. This report describes the initial meeting of a National Science Foundation-funded cross-institutional collaboration of interdisciplinary science, technology, engineering, and mathematics (STEM) education researchers interested in exploring the use of automated text analysis to evaluate constructed-response assessments. Participants at the meeting shared existing work on lexical analysis and concept inventories, participated in technology demonstrations and workshops, and discussed research goals. We are seeking interested collaborators to join our research community.  相似文献
