Radio is migrating to digital transmission, expanding its offerings to include captioning for individuals with hearing loss. Text display radio requires a large amount of word throughput with minimal screen display area, making good user interface design crucial to its success. In two experiments, we presented hearing, hard-of-hearing, and deaf consumers with National Public Radio stories converted to text and examined their preferences for and reactions to midsized and small radio text displays. We focused on physical display attributes such as text color, font style, line length, and scrolling type as well as emergency alert messages and emergency prompts for drivers, announcer identification schemes, and synchronization of audio and text. Results suggest that midsized, Global Positioning System (GPS)-style displays were well liked, synchronization of audio and text was important to comprehension and retrieval of story details, identification of announcers was served best with a combination of name change in parenthesis and color change, and a mixture of color and flashing symbols was preferred for emergency alerting. 相似文献

This paper describes the ways that students’ problem-solving behaviors evolve when solving multi-faceted, context-rich problems
within a web-based learning environment. During the semester, groups of two or three students worked on five physics problems
that required drawing on more than one concept and, hence, could not be readily solved with simple “plug-and-chug” strategies.
The problems were presented to students in a data-rich, online problem-based learning environment that tracked which information
items were selected by students as they attempted to solve the problem. The students also completed a variety of tasks, like
entering an initial qualitative analysis of the problem into an online form. Students were not constrained to complete these
tasks in any specific order. As they gained more experience in solving context-rich physics problems, student groups showed
some progression towards expert-like behavior as they completed qualitative analysis earlier and were more selective in their
perusal of informational resources. However, there was room for more improvement as approximately half of the groups still
completed the qualitative analysis task towards the end of the problem-solving process rather than at the beginning of the
task when it would have been most useful to their work. 相似文献

Many residence hall staff have attempted to align the academic subculture of the faculty with the opposing extracurricular subculture of students by moving closer to the academic sector. Studies at Harvard University and at Hampshire College are summarized to indicate the failure of traditional house systems or residence hall programming to successfully bridge the gap between the academic and living subcultures. It is suggested that student personnel staff should focus on their unique contribution in higher education: the facilitation of students' personal development and interpersonal communication skills. 相似文献

This study investigated the hypothesis that prompting students to self-assess their interest and understanding of science concepts and activities would increase their motivation in science classes. Students were randomly assigned to an experimental condition that wrote self-assessments of their competence and interest in science lessons or a control condition that wrote summaries of those same lessons. Writing activities were 10?min long and were given approximately once a week for eighteen weeks. Student motivation was assessed via self-report surveys for achievement goals and interest in science before and after the intervention. Students in the experimental condition showed higher endorsement of mastery goals and reported greater situational interest in science topics after the intervention compared to students who summarised the lessons. Increases in situational interest predicted higher individual interest in the domain. Results indicate an instructional practice requiring just 3?hours out of a semester of instruction was sufficient to achieve these effects on motivation in science classes. 相似文献

This article presents a microanalysis of how a group of primary school teachers deals with research evidence in their work. Based on analysis of a group of Norwegian teachers’ interactions over issues of educational research and research-based knowledge, we find that teachers’ representations of educational research particularly center on the following issues: educational research being perceived as circular, ‘polyphonic’, and a matter of accommodation to their experience-based knowledge. These metaphors also shed light upon the dilemmas that arise when research evidence meets teachers’ more contextual knowledge. We conclude that teachers’ practice-based evidence may take new forms with an increased policy focus on research-based evidence, as well as bringing forth challenges for teacher work and professionalism. 相似文献

This study examines how participation in a verbal exchange during an inquiry-based classroom activity allows three college
students and their science instructor to use linguistic signs (choices of words, grammatical structures, discursive structures,
prosody and poetic discourse) to construct authority and expertise. Our work explores linguistic and interactional processes
of identification (the dynamic construction and transaction of expert identity) and examines how discursive strategies adopted
by the professor at different moments of the verbal exchange influence the students’ subsequent discursive practices and perceptions
of authority. We adopt a dialogic, socio-constructivist perspective on identity, viewing personal identities as being partially
constructed via interactional positioning. Our findings reveal that the attainment of expertise involves two different types
of language-mediated processes: the transmission of a professional vision or intension and the emergence of a perception of
agency among students. The former is centered on referential-denotative meanings of speech (elicitation of standard account
and operational definition) while the latter requires effective use of pragmatic–performative functions of speech (non-evaluative
and more than minimal recipient practices). Consideration is given to the need for science instructors to be able to utilize
pragmatic functions of language strategically to encourage students to position themselves within the identity of science
expertise. 相似文献

The localization,diagnostic, and monitoring functions of student ratings in a model for improving university teaching 总被引:1,自引:0,他引:1
Daniel S. Sheehan 《Instructional Science》1976,5(1):77-91
A diversity of student questionnaires are used by colleges and universities to provide data on faculty teaching performance. Yet the purposes for collecting this data are frequently unclear, and at times superficial. Rarely is student rating data used as a tool to improve faculty teaching. A more relevant approach incorporates a variety of types of student ratings into a model for improving university teaching. One type of student rating data is used to identify broad instructional problem areas. Another type pinpoints probable causes and solutions for the instructional problems. Instructional improvement procedures are designed on the basis of this data. A third type of student rating data evaluates the instructional improvement procedures and indicates when modifications are needed. In addition to these three types of student ratings, and the generation of appropriate questionnaires, this paper presents an overview of the teaching improvement model and discusses its effectiveness. 相似文献

The use of the Internet in the classroom has often been characterized as a practice that disconnects the teacher from traditional forms of externally imposed influence. This paper examines this assertion by mapping the emerging field of cybereducation and considering how endemic knowledge is contextualized by national curricular authorities. The field theories of Pierre Bourdieu and Basil Bernstein are employed in order to demonstrate the relationship between expert discourse and classroom pedagogy, using the National Grid for Learning (NGfL) as a case study. This attempt to capture the dynamics of cybereducation ultimately suggests how this emergent intellectual field’s fragmentation and decoupling from State education forces offers policymakers the capacity to influence use. Progress of the UK government in integrating knowledge from an emergent educational field with its incumbent priorities is gauged, demonstrating the way in which national education officials have attempted to constrain potential departures from unregulated, officially mandated curriculum. 相似文献

Three experiments have been devoted to the application of the methodology developped by Anderson, N. H. (1981, 1982) in the framework of the Information Integration Theory to the problem of the mastery by children (14 old) of the relations between the notions of mass, volume and volumic mass. It appears that, having to judge of the mass values of diverses objects from given values of volume and volumic mass, a majority of pupils are able to take account of the positive link between the mass on the one part and the volume and the volumic mass on the other part but apply an additive type integration rule. However, a minority of pupils are able to apply a normatively correct multiplicative rule. Concerning the judgements of volume values from given mass and volumic mass values, and the judgements of volumic mass values from given mass and volume values, a majority of pupils apply a soustractive integration rule. In these two cases however the integration patterns are extremely variegated. The relation between the algebraic level of analysis of the judgement data and an information processing level of analysis of the same data is discussed. The use by teachers of the paradigm presented in the study with the aim of improving upon the current evaluation methods is proposed. 相似文献
