This study investigates the experience of teaching of 19 teachers who are teaching on university courses involving face-to-face and on-line learning. The teachers are asked about how they think about learning technologies and how they approach the design and teaching of their courses across these two contexts. Results show that there are qualitatively different ways of thinking about learning technologies that relate logically and positively to qualitatively different ways of designing and teaching using learning technologies. The results have implications for teachers and those interested in maximising the likelihood of learning for university students when teachers teach with learning technologies. 相似文献

The purposes of this study were to (a) determine how three generations of females from the same families perceived the grandmothers, (b) identify strengths and learning needs of the grandmothers, and (c) recommend guidelines and curriculum themes to assist the grandmothers in adjusting to change. The 348 Taiwanese subjects included grandmothers (n = 116), mothers (n = 116), and teenage granddaughters (n = 116). Subjects completed a Mandarin version of the Grandparent Strengths and Needs Inventory. Each generation reported favorable ratings for grandmothers on the frustration, difficulty, information needs, and satisfaction scales. Unfavorable ratings were given for the teaching and success scales. 相似文献

A new perspective is needed on the great debate in literacy instruction. Rather than the current dichotomy between whole language and phonics, we propose an approach that integrates comprehension and decoding into a system designed around the principles of student-centered, authentic instruction in a socially engaging context. This approach reflects the research on meta-cognitive and social-constructive literacy. We discuss concepts and practices for realizing these principles in programs for students in US schools whose native language is English and those for whom Spanish is the language of the home. We consider the advantages of bilingual programs that promote awareness of the function of print codes within and across languages. 相似文献

Delivering public services through the SMS channel is popular in developed and developing countries, and it has demonstrated its benefits. However, citizens' acceptance of the services is still an issue. This paper presents a study on user acceptance of SMS-based e-government services. Constructs of the proposed model were derived from a survey on citizens' motivations for using SMS-based e-government services (142 respondents from 25 countries), prominent theories on individual acceptance of technologies, and current studies on user acceptance of SMS and e-government services. The model was validated using data from 589 citizens in three cities in Indonesia, who are non-adopters. The relationships between the factors then were compared with data from 80 adopters of SMS-based e-government services in Australia. The proposed model explains what factors influence non-adopters to accept SMS-based e-government services, and the comparison explains the relative importance of the factors for the adopters. The findings are promising for governments who wish to evaluate a new SMS-based e-government system very early in its development in order to assess potential acceptability and for governments who would like to diagnose the reasons why an existing SMS-based e-government service is not fully acceptable to citizens and to take corrective action to increase the acceptability of the service. 相似文献

ABSTRACTUser feedback told the story of the largest and busiest campus library being dated in both physical form and programmatic function. Under the framework of a newly-developed strategic plan, library leadership initiated a comprehensive and inclusive assessment program to understand fully user needs by engaging users, campus partners, and, importantly, library personnel. Simultaneously, they embarked on a review of change management literature for guidance on implementing the required transformation. Informed by the change management philosophy of John Kotter, the library utilized the findings of the assessment program to craft and implement a sustainable transformation of its services, staffing, and spaces. 相似文献

This study describes pre-kindergarten teachers’ use of kindergarten transition practices and examined the extent to which these practices were associated with kindergarten teachers’ judgments of children's social, self-regulatory, and academic skills upon their entry into kindergarten. Participants were 722 children from 214 pre-kindergarten classrooms participating in the National Center for Early Development and Learning's (NCEDL) Multi-State Pre-kindergarten Study. Of nine transition practices intended to promote children's adaptation to kindergarten, pre-kindergarten teachers reported implementing, on average, six transition practices, with notable variation across pre-kindergarten classrooms. Children were judged by their kindergarten teachers to have more positive social competencies and fewer problem behaviors when they attended pre-kindergarten classrooms in which more transition activities were implemented and, specifically, in which teachers discussed curricula or specific children with kindergarten teachers. In addition, positive associations between kindergarten teachers’ perceptions of children's social competence and pre-kindergarten transition activities (total number of activities and activities that children experience directly) were stronger for children who experienced social and economic risks. Implications of these findings related to alignment across the pre-kindergarten to kindergarten settings to improve children's school readiness are discussed. 相似文献

AbstractIn two experiments, participants performed visual detection, visual discrimination and decision-making tasks, in which a binary (left/right) response was required. In all experimental conditions, a spoken word (“left”/“right”) was presented monaurally (left or right ear) at the onset of the visual stimulus. In Experiment 1, 26 non-athletes located a target amongst an array of distractors as quickly as possible, in both the presence and absence of spoken cues. Participants performed superiorly in the presence of valid cues, relative to invalid-cue and control conditions. In Experiment 2, 42 skilled netballers completed three tasks, in randomised order: a visual detection task, a visual discrimination task and a netball decision-making task – all in the presence of spoken cues. Our data showed that spoken auditory cues affected not only target detection, but also performance on more complex decision-making tasks: cues that were either spatially or semantically invalid slowed target detection time; spatially invalid cues impaired discrimination task accuracy; and cues that were either spatially or semantically valid improved accuracy and speeded decision-making time in the netball task. When studying visual perception and attention in sport, the impact of concomitant auditory information should be taken into account in order to achieve a more representative task design. 相似文献

This article examines the effect that postsecondary education has on earnings and the duration of time spent in the Social Security disability programs for young persons who are deaf or hard of hearing. Our hypothesis is that investments in postsecondary training increase the likelihood of employment for persons who are deaf or hard of hearing and thus reduce dependency on disability-related income support programs. A longitudinal data set based upon records from the National Technical Institute for the Deaf and Social Security administrative records is used for this analysis. We find that those who graduate, even those who graduate with vocational degrees, experience significant earnings benefits and reductions in the duration of time spent on federal disability programs when compared with those who do not graduate with a degree. This finding suggests that reductions in the duration of time spent on Social Security programs are not limited to those with the highest level of scholastic aptitude and that investments in post-secondary education can benefit a broad group of deaf and hard-of-hearing persons. In addition, the data show that individuals who attend college, but withdraw before graduation, fair no better economically than individuals who never attended college. 相似文献
