From a larger longitudinal study of 610 fourth graders in 17 inner city schools, 40 students were randomly selected from 10
classrooms rated high (i.e., top quartile) or low (i.e., bottom quartile) in quality of writing instruction in grades 3 and
4. The written compositions of these students were scored in three ways: (1) according to a rating scale within a reliable
scoring rubric, (2) according to countable surface features such as words correctly sequenced, and (3) according to the frequency
of specific phonological, morphosyntactic, and orthographic errors in the children’s writing. A multivariate analysis of variance
was conducted to examine whether quality of writing instruction in grades 3 and 4 predicted students’ writing performance
at the end of grade 4. Students who received high quality instruction in fourth grade wrote longer compositions with more
correctly spelled words than those who had poor quality writing instruction. There was a tendency for two years of quality
instruction to be better than one, and, among students who had poor quality instruction in grade 3, compositions were longer
in grade 4 when they received quality instruction in fourth grade. Foundational problems of language formulation, production
and representation, however, were ubiquitous across the sample. Although these students were within the average range on standardized
reading tests, spelling and writing were not developing at average levels. The study confirms the urgent need for more and
better writing instruction for high risk, minority children. 相似文献

This study takes a relatively new direction in researching virtual learning communities (VLCs) as it explores the ways in which VLC membership can support lifelong learning and impact on individual learning careers and professional identities beyond the life of the community. The case study spans 4 years. The findings suggest that through the process of engaging in a VLC, individuals may change their ‘horizons of action’ leading to new learning and career trajectories. In particular, the study demonstrates how membership of a VLC supported and enabled some individuals to transform their learning careers and to make significant life changes. Other members developed their learning careers in an incremental manner that led to increased innovation and professional expertise. The findings suggest that VLCs are successful in supporting individual change and career development when they provide the ‘comfort zone’ of a secure and supportive virtual environment. 相似文献

The study identified social, educational, and demographic characteristics of deaf postsecondary students who demonstrated strong reading and writing skills. Questionnaire information, information from institutional databases, and in-depth personal interviews were used to identify factors and characteristics that positively influenced the attainment of strong academic literacy skills. Among the areas investigated were school experiences, reading and writing experiences, study habits and attitudes, communication preferences, personality traits, and home and family background. Results of the study generally support previous work conducted with talented hearing youth. Several primary themes emerged from the study: heavy parental involvement in early education and educational decisions, differing modes of communication but extensive family communication, early exposure to and intensive experiences with reading and writing, an enjoyment of reading, a relatively limited social life, high parental and secondary school expectations, the importance of television, and positive self-image. 相似文献

Summary Prejudice and discrimination can be both subtle and blatant. It offends and affects both young and old. If our goal as teacher
or caregiver is to guide children to grow up in a world that celebrates diversity and strives to reduce and eventually eliminate
destructive forces such as racism and sexism, then we must analyze our homes and clssrooms through a wide-angled lens that
allows us to see the presence of ageism and its manifestations. In a society that seems to be increasingly segregated by age,
we have a tremendous responsibility to examine ways in which we endorse and teach values regarding the worth and dignity of
each human being. We must begin to direct the experiences children have toward the development of positive attitudes toward
all people including the elderly.
When young children digest behaviors, images, and perceptions, they will begin to form attitudes that have a powerful influence
on their present and future behavior. It is only as young and old alike are able to understand and develop healthy attitudes
toward their own aging process and cultivate the positive attitudes that allow them to develop intergenerational relationships
that they will be able to realize their own full potential. 相似文献

Attitudes to science develop early in life. In early childhood, the almost exclusively female staff members lack confidence
in the area of science, and are therefore unable to develop an adequate science program for their children. In an action research
project involving one third of the adults staffing a playcentre, during one term, the science programme in the centre was
considerably improved, on measures of dialogues with the children, and of planning activities specifically for science. The
staff members, mothers in the playcentre, reported increased confidence in talking with children about science topics, and
a significant change in their interaction patterns both with their own families and with other children in the playcentre
science programme. The action research method was found to be particularly helpful in supporting the group of parents in improving
their centre's science program.

ABSTRACTIt is widely known that there is a discrepancy between educational policy on the one side, and teaching and learning practices on the other. Most studies have been focusing on the sociocultural and micropolitical frames that shape teachers’ understandings and enactments of teaching, and that cause the vast diversity of classroom practices around the world. This article wants to draw attention to the ‘politics of use’ in teachers’ work: how teachers mobilize larger political narratives when implementing curriculum reform. Arguably, these narratives provide a shortcut between the central government and street-level actors, thus circumventing the logics of these actors’ immediate institutional environments.In order to showcase the politics of use, the article uses the case of education for creativity as it is designed for and practiced at Chinese schools. The case reveals how education for creativity is compromised by requirements emanating from larger political programs when implemented in Chinese classrooms. The article challenges the view that educational policy necessarily moves through a trickle-down process, from higher to medium to lower-level actors. In cases of strong ideological alignment between street-level actors and central state actors, educational policy may in fact sidestep and hence neutralize important institutional actors. 相似文献

Faculty Views of Student Evaluation of College Teaching 总被引:1,自引:1,他引:1
The literature abounds with psychometric studies of course evaluation measures and articles debating the merits of student ratings of instruction, but little research has focused on faculty perceptions of this procedure. In the present study faculty perceptions are explored at a teachers' college where evaluation is carried out annually on a sample of courses. The sample includes 101 instructors who completed the research questionnaire. Faculty attitudes reflected a broad range of responses towards validity of student ratings, and their usefulness for improving instruction. Although overall attitudes were mildly positive, few instructors reported changing instruction as a result of student ratings. Moreover, few supported sending evaluation results directly to college administrators or publishing them for student consumption. 相似文献

Risk taking is a multidimensional construct. It is currently unclear which aspects of risk‐taking change most during adolescence and if/how sex hormones contribute to risk‐taking tendencies. This study applied a longitudinal design with three time‐points, separated by 2 years, in participants aged 8–29 years (670 observations). The Balloon Analogue Risk Task, a delay discounting task, and various self‐report questionnaires were administered, to measure aspects of risk taking. Longitudinal analyses demonstrated mostly nonlinear age‐related patterns in risk‐taking behavior and approach‐related personality characteristics (peaking in late adolescence). Increased testosterone and estradiol were found to increase risk‐taking behavior and impulsive personality, but decrease avoidance‐like personality. This study demonstrates that risk taking is most pronounced in mid‐to‐late adolescence and suggests that sex hormones accelerate this maturational process. 相似文献

This investigation examined the extent to whichcurricular choice and incorporation of phonemicawareness (PA) into the kindergarten curriculumaffects growth in kindergarten literacy skillsand first-grade reading and spelling outcomesin 114 classrooms in 32 Title 1 schools for4,872 children (85% African American). Literacy curricula were described as havingmore or less teacher choice and more or less PAand were implemented with ongoing professionaldevelopment. Observations of curriculumfidelities and ratings of student behavior werealso obtained. Alphabetic instruction withoutPA was not as effective as alphabeticinstruction with PA. However, effectiveinstruction in PA and alphabetic codingappeared to be as much a consequence of ongoingprofessional development as it was a functionof prescribed PA activities. Results providelarge-scale classroom support for findings onPA reported by the National Reading Panel[(2000).

The long term aim of this study is to document changes in the nature and level of conceptual understanding revealed by a cohort
of undergraduate nursing students. The outcome of such a study may be used in future review and redesign processes by curriculum
planners. Conceptual understanding of physiology and pharmacology, areas which are central to nursing studies depends, in
turn, on an understanding of certain chemical concepts. This paper describes the group cognitive structure of 60 first year
preservice nursing students, with respect to 21 basic chemistry concepts. Group cognitive structure is represented by non-metric
multidimensional scaling of data obtained from individual concept maps prepared by students. The impact of prior studies in
chemistry on the level of understanding revealed is discussed.
