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

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

Whereas research in MicroSystems Technology (MST) has grown rapidly over the last twenty years, the education of engineers at postgraduate level is still in its infancy. The number of dedicated MST research institutions, companies and university laboratories worldwide has grown at a dramatic rate and all require trained individuals who can be immediately operational in the workplace. With the possible exceptions of Germany and Switzerland, the authors of this article believe that the training requirements for such scientists, engineers and technicians have not been satisfactorily addressed as yet. Realising the need for adequate training in MST, the British funding agency for research in science and engineering, the EPSRC (Engineering and Physical Sciences Research Council) awarded a substantial grant to Heriot-Watt University in order to set up a Masters Training Package (MTP). The context of this grant, the syllabus developed for this Master of Science as well as its implementation are presented in this article. Advantages and drawbacks of block-based delivery of the course are presented from a pedagogical point of view for the different categories of students (full-time students, part-time students and company delegates). 相似文献

Contemporary discourses of social justice in education, disability, mental health, social policy and feminist studies are refracted increasingly through concerns about psychological and structural vulnerabilities created by the crises of late capitalism. Focusing on developments in British social policy generally and educational research specifically, this paper uses the authors' contrasting perspectives on two discernible discourses of vulnerability emerging in these contexts. One elevates the recognition of collective vulnerability as a springboard for new conceptualisations of resistance that disrupt materialist narratives of the human subject as a coherent, unified and rational agent of history. A second discourse offers a materialist understanding that locates vulnerability as both driver and product of a ‘therapeutic culture’, arguing that a psycho-emotional focus for vulnerability offers a diminished and ineffective subjectivity that belies rhetorics of resistance. These contrasting perspectives generate and emerge simultaneously from new understandings of the human subject. The paper evaluates the implications of using vulnerability to frame expectations of human subjects for everyday educational practices and relationships. It concludes by suggesting empirical questions that need exploring. 相似文献

Despite the importance of sign language interpreting for many deaf students, there is surprisingly little research concerning its effectiveness in the classroom. The limited research in this area is reviewed, and a new study is presented that included 23 interpreters, 105 deaf students, and 22 hearing students. Students saw two interpreted university-level lectures, each preceded by a test of prior content knowledge and followed by a post-lecture assessment of learning. A variety of demographic and qualitative data also were collected. Variables of primary interest included the effects of a match or mismatch between student interpreting preferences (interpreting vs. transliteration) and the actual mode of interpreting, student-interpreter familiarity, and interpreter experience. Results clarify previous contradictory findings concerning the importance of student interpreting preferences and extend earlier studies indicating that deaf students acquire less than hearing peers from interpreted college-level lectures. Issues relating to access and success in integrated academic settings are discussed as they relate to relations among student characteristics, interpreter characteristics, and educational settings. 相似文献

In this article, we explore the meaning potentials of teacher education in terms of the significance of a research-based approach and the different pedagogic identities that such an approach implies. The study’s aim is to examine the important factors for education to be considered research-based and to identify and analyse the research base of teacher education in Sweden. The results from the analysis of a large number of course documents and from a survey administered to teachers and students in four teacher education programmes indicate that the emerging potential meaning is that teacher education is generally a strongly framed professional education with a relatively weak and adapted research base. The analysis of the classification and framing of disciplinary content and pedagogy in the Swedish teacher education curriculum points at different pedagogic identities emerging from the different meaning potentials that are made available to the students. We argue that a thorough understanding of research-based teacher education needs to be grounded in both course content and its research base as well as other possible pedagogical aspects of research-based education; the education as a whole must be included in the concept of research-based education. 相似文献

Accountability-oriented reforms demand immediate and continual gains on achievement test, for all students, and without diminishing other outcomes or undermining instruction. This paper describes a framework for aligning classroom assessment and external testing with the aim of negotiating these seemingly contradictory goals. The framework varies the sensitivity to instruction and the representations of knowledge across approaches to assessment. Cycles of design- based studies successively refine relationships between a curriculum and the frame that each assessment provides. Doing so, we argue, leverages the unique formative and summative balance across assessments in order to scaffold learning and demonstrate the “consequential” validity of our strategy without compromising curricula, instruction, or the “evidential” validity that warrants their continued use. 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
