Although textbooks on educational research give only scant attention to survey research methodology, its extensive use in education provides a strong rationale for improving the preparation of educational researchers in effectively applying survey methods. This study reviews methods for dealing with nonresponse bias, the primary problem presented by survey methods. It also provides an updated review of the literature of studies investigating the effectiveness of incentives to increase survey response rates. We hypothesized that a reanalysis of reviewed studies, using a linear trend test, would resolve the inconsistencies found regarding the effectiveness of incentives to increase response rates. The results of the reanalysis and guidelines for educational researchers in systematically selecting and applying incentives to increase response rates are discussed. 相似文献
This study built on prior research regarding the effectiveness of the National Center for Research in Early Childhood Education (NCRECE) course by exploring the individual course components. Core aspects of course engagement and performance were described and examined in relation to improvements in the observed quality of teacher–child interactions. Teacher characteristics were also examined as predictors of course engagement and performance. A sample of 150 preschool teachers participated in a semester-long, credit-bearing, college course designed to improve the quality of their emotional, organizational, and instructional interactions with children. Teachers’ participation and performance in the course were high on average. Teachers’ skill level in accurately and specifically explaining other teachers’ instances of effective teacher–child interactions was related to improvements in their own observed teacher–child interactions. Finally, teachers with an early childhood major and those endorsing child-centered beliefs displayed better skills in detecting other teachers’ high-quality interactions with children. Results are discussed in relation to designing more effective early childhood professional development programs. 相似文献
This clinical treatise discusses this author's concept of “professorial melancholia,” a progressive emotional process characterized by the negating of a university professor's professional motivation, positive attitudinal focus, and adequate personal self-esteem. 相似文献
An eight-item instrument was constructed to measure the skills represented by four of Carkhuff's dimensions (scales) of facilitative interpersonal functioning. These items consisted of stimulus statements on a color videocassette, introduced by a narrator and performed by actors. Subjects responded by writing what their verbal and nonverbal responses would be in the situation presented. Reliability coefficients (.77 and .80), concurrent validity (.75) and construct validity via factor analysis are presented. Results demonstrate the feasibility of this approach to measuring Carkhuff's dimensions. Suggestions for further research are included. 相似文献
The temporal processing capabilities of 15 children with dyslexia versus 15 age-matched and 15 reading-matched controls in a word identification task were examined. The hypothesis underlying the present experiment was that word recognition would be inferior in children with dyslexia, relative to controls, when the task demanded the temporal integration (sequencing) of two-syllable words. Such a hypothesis must predict that one-syllable word recognition does not distinguish between these two populations and that these effects cannot be accounted for in terms of eye movement differences. To test this hypothesis, one- and two-syllable words displayed for 100, 300, and 3,000 msec were required to be identified. The results yielded evidence of decreased accuracy of word identification by the children with dyslexia in the two-syllable, 300-msec condition, as predicted. A second experiment was unable to uncover any differences in eye movement behaviors that could account for the effects observed in the first experiment. The results are discussed in terms of potential sequential processing deficits in individuals with dyslexia. 相似文献
The first part of the article provides a historical account of the broad phases of development that educational television has passed through as a result of social and technological influences:
its beginnings in broadcasting in the fifties and sixties;
its development through the video age in the seventies and eighties, with widening scope and opportunity as a result of developments in production and reception/recording equipment and an expansion of communication channels;
its present potential, at the dawn of the interactive age, as a result of the influences of new technology.
The article then examines the problems of integrating new television‐related technologies into the educational system and draws attention to:
the frequent past failures of the educational system to fully exploit new technologies, resulting in superficial integration and ineffectual use;
the current tensions between the traditional educational technology approach and the drives behind much new technology;
the need for appropriate systems and structures to ensure that the evaluation of such new technologies is properly resourced and effectively carried out.
Using a Black Feminist Thought framework, this phenomenological study focused on lived experiences with mentoring relationships among 38 Black women in doctoral programs in multiple disciplines across universities in the United States. Although emerging studies on Black women in academia acknowledge the significance of mentorship and the reality of discrimination at the intersection of race and gender, the literature lacks empirical support pertaining to the formation and outcomes of mentoring relationships, specifically for Black women in doctoral education. Findings from this study suggested four central themes in the mentoring relationships among Black women in doctoral programs: (a) organic evolvement, (b) shared identity/mutual interest, (c) personal transformation and (d) increase in access and opportunity. Implications for future research, policy, practice and education across disciplines are offered. 相似文献
Five pigeons pecked lighted keys for food reinforcers delivered by several multiple variable interval 2-min variable interval 2-min schedules. At different times, the components of the multiple schedule both supplied food reinforcers, both supplied water, or one supplied food and the other supplied water. Rates of responding during the water component of the food-water schedule were lower than the rates during comparable components of the water-water schedules (negative contrast). But, the rates of responding during the food component of the food-water schedule were not greater than the rates of responding during comparable components of the food-food schedules (absence of positive contrast) at two different levels of water deprivation. These results raise questions about several theories of behavioral contrast, and they may restrict the scope of any theory that attributes positive and negative contrast to symmetrical factors. 相似文献
