The study described in this article takes the view that distance education programs are dynamic systems with multiple constituencies.
Literature on distance education programs as complex systems and on the critical constituency approach to program evaluation
was used to guide the development of a questionnaire designed to assess the components of a distance education program. Instrument
development was conducted in four phases using both quantitative and qualitative methods. The data from this study suggest
that there are four major components of effectiveness in distance education programs: instruction, management, telecommuting,
and support. Within each of these components there are from two to five subcomponents, 14 components in all, which can be
used to assess distance education programs. The assessment scale which was developed measures these four components and their
subcomponents. 相似文献

This study investigated classroom practices of 38 teachers enrolled in university masters' degree programs in educational technology and in other areas of education. The classroom practices related to five key concepts associated with educational technology: (a) learner-centered instruction, (b) instructional design, (c) media and technology, (d) assessment, and (e) instructional alignment. Teachers rated their frequency of use of desirable practices in these five areas on a 30-item Likert type survey. In addition, one class of students per teacher rated its own teacher's frequency of use of the practices on 20 items parallel to items on the teacher survey. The mean overall rating across all teachers for the classroom practice items was very close to Often, or 4.0, on the 5-point scale. There were few reported differences between the teachers enrolled in educational technology programs and those enrolled in other education programs. Student ratings indicated less frequent teacher use of the desirable practices on 16 of the 20 common items, with significantly lower student ratings on 8 of these items. However, there was strong teacher-student agreement on several other comparisons.The study reported in this article was conducted as a doctoral dissertation at Arizona State University. 相似文献

The study investigated school psychologists' continuing professional development (CPD) needs and their relationship to selected demographic factors, preservice training, incentives, and typical engagement in various CPD activities. A survey questionnaire was mailed to 500 randomly selected National Association of School Psychologists (NASP) members, and responses were received from 235. Respondents reported their greatest CPD needs to be in the areas of direct service and consultation. No demographic variables were related to respondents' CPD needs. Few preservice training or incentive factors were related to CPD needs. Respondents' perceived value of preservice training in CPD management was related to their CPD needs, but few respondents reported that they had received this type of preservice training. Several personal incentives for CPD, including self‐assessment of CPD needs, opportunity to practice new skills and receive feedback during CPD training, and opportunity to evaluate the effectiveness of CPD training and CPD goal attainment were related to CPD needs. Respondents' CPD needs in each specific skill area, including direct service, consultation, assessment, program planning and evaluation, supervision, and research, had significant but low correlations with the amount of actual CPD activity in the respective skill area. © 2001 John Wiley & Sons, Inc. 相似文献

AbstractMaternal dietary habits influence maternal and foetal health, representing a pathway for intervention to maximise pregnancy outcomes. Advice on energy intake is provided on a trimester basis, with no additional calories required in the first trimester and an additional 340?kcal?d?1 and 452?kcal?d?1 needed for the second and third trimesters. Energy intake depends on pre-gravid body mass index (BMI); underweight women are recommended an increase of 150, 200 and 300?kcal?d?1 during the first, second and third trimester, normal weight women an increase of 0, 350 and 500?kcal?d?1 and obese women an increase of 0, 450 and 350?kcal?day?1. The recommendations for carbohydrate and protein intake are 175?g?d?1 and 0.88–1.1?g?kgBM?d?1, with no change to fat intake. The number of pre-gravid obese women is rising; therefore, we need to regulate weight in women of childbearing age and limit gestational weight gain to within the recommended ranges [overweight women 6.8–11.3?kg and obese women 5.0–9.1?kg]. This can be achieved using nutritional interventions, as dietary changes have been shown to help with gestational weight management. As pregnancy has been identified as a risk factor for the development of obesity, normal weight women should gain 11.5–16.0?kg during pregnancy. While some research has shown that dietary interventions help to regulate gestational weight gain and promote postpartum weight loss to some extent, future research is needed to provide safe and effective guidelines to maximise these effects, while benefitting maternal and foetal health. 相似文献

Joyce Harrison, an educational psychologist in Hampshire, argues that there are many more children with autistic spectrum disorders in mainstream schools than is realised, and suggests that recent research can be used to help class teachers to devise strategies to improve learning opportunities for their pupils. 相似文献

Thepractice of evidence-based health care requires that information on methodology be identifiedfrom databases such as MEDLINE. Up until this year there have been no designated medicalsubject headings (MeSH) for evidence-based health care. ‘EVIDENCE-BASEDMEDICINE’ appears as a MeSH term from 1997. The absence of designated MeSH forthis concept prior to 1997 provides a challenge to the searcher. This paper describes the creationof a MEDLINE search strategy to retrieve articles on the methods of evidence-based health carepublished prior to the introduction of the new term, where an optimal combination of free-textand MeSH terms is required to identify relevant material. The study examines both free-text andsubject heading searching and attempts an optimal balance of sensitivity and specificity. It beginsby examining separate free-text and subject heading searches. Sensitivity of the subject headingsearch was 33% and specificity 80%, while the free-text search produced asensitivity of 50% and a specificity of 67%. The final strategy, combining bothapproaches, was more successful with sensitivity reaching between 82 and 90% andspecificity 83%. It is therefore possible to devise a search strategy to retrieve articles on themethods of evidence-based health care with relatively successful rates of sensitivity andspecificity. The limitations of MEDLINE, however, necessitate the use of additional approachesin identifying articles on the methods of evidence-based health care. 相似文献

Difficulty processing sensory information may impede progress in school for students with autism spectrum disorder (ASD). We explore the relationship between sensory processing and school performance in 26 high‐functioning youths with ASD and 26 controls (age 8–14) using measures of sensory, social, cognitive, and academic functioning. In the ASD group, bivariate Pearson correlations indicated a significant positive relationship between intelligence quotient (IQ) and the School Competence Scale (SCS) of the Child Behavior Checklist (CBCL), and a significant negative relationship between Dunn's Sensory Processing Framework and SCS scores. Final hierarchical multiple linear regression model accounting for SCS scores in ASD included IQ, ADHD symptoms, and sensory features. An interaction between increased sensory sensitivity with reduced sensory avoidance behaviors explained the greatest amount of variance in SCS, meaning school performance is lowest for children with greater hypersensitivity and fewer avoidance behaviors. Results indicate a strong impact of sensory processing on school performance in ASD. 相似文献

Challenging discourses of aspiration: The role of expectations and attainment in access to higher education 下载免费PDF全文
Raising the proportion of young people from disadvantaged backgrounds progressing to higher education has been a key policy objective for successive governments in the UK since the late 1990s. Often this has been conceptualised as a problem with their ‘aspirations’, with the solution being seen as the provision of ‘aspiration‐raising’ activities to promote higher education to those thought to have the potential to progress. Recent large‐scale studies cast strong doubt on this hypothesis by demonstrating that aspirations are not generally low, that different social groups have similar levels of aspiration and that school attainment accounts for nearly all the differences in participation rates between social groups. This article draws on data from a national project exploring efforts to widen participation across two generations of practitioner‐managers in England, focusing on their conceptualisations of the field and their constructions of ‘successful’ activities. It uses the lens of ‘possible selves’ (Markus & Nurius, 1986 ) to argue that too much policy emphasis has been placed on the aspirations of young people, rather than either their academic attainment or their expectations, which are shaped by the normative expectations of the adults surrounding them. In addition, the more expansive concepts of widening participation that were present a decade ago have become less common, with a shift towards activities with a clear role in institutional recruitment rather than social transformation. The article concludes with alternative suggestions for policy and practice. 相似文献
