An action research project, managed by a graduate student, resulted in the development of an academic website as an effective internal and external communication tool. The main focus of the investigation was to uncover the tacit knowledge held by staff in the Department of Management Communication through a series of in-depth interviews, a focus group, and informal conversations to facilitate the development of a website which effectively captured this knowledge. The cyclical nature of the action research methodology provided the flexibility to ensure that issues could be addressed as they arose; although the relative unfamiliarity of staff with action research methodologies created other barriers to be overcome. The key outcome for the staff was that they became aware of the extent of the tacit knowledge and resources available in the department; they valued these, and they utilised them effectively. The research highlights the different learning outcomes experienced by the student researcher, supervisors and departmental colleagues.  相似文献

Internationally, considerable reform in science education is occurring which promotes constructivist philosophies and advocates constructivist-inspired pedagogical strategies that are new to many teachers. This paper reports on the supporting factors necessary for teacher professional growth and the issues of concern that were evident during one primary teacher's successful implementation of a unit of work based on a draft of a new state-wide science syllabus which proposes such approaches. One researcher (CEP) provided guidance during the writing and implementation of the unit through professional development workshops complemented by ongoing collegial support. The analysis of the teacher's practice reveals that professional growth required a willingness of the teacher to engage with change and modify his professional practice. The support factors for teacher growth consisted of an appropriate program of professional development, teacher understanding of the elements of the curriculum innovation, and successful experiences in implementing new approaches. In contrast, the issues of concern were: the adequacy of support for planning including the time required to understand the innovation and make changes to teaching practice; science equipment; teacher knowledge; classroom management strategies; and ways to cope with change. Understanding of these support factors and issues of concern is vital for the successful implementation of science curriculum innovations.  相似文献

A project designed to foster the full and fair participation of girls in high-school science classes addressed obstacles, both perceived and actual, to equal participation. In order to modify existing classroom techniques and environments, a Teacher Intervention Program was designed. By means of a workshop and periodic personal communications, teachers were sensitized to the importance of a stimulating, gender-free learning environment. In addition, they were presented with a variety of methods and materials which had been shown to encourage girls in science. Twelve teachers, who were selected randomly, taught in diverse communities throughout one Midwestern state. The subjects tested were students in 24 general biology classes taught by the 12 teachers. Although both qualitative and quantitative measures were used during the research, only the quantitative results are discussed in this paper. Using ANOVA's, treatment group by student sex, a comparison of the mean scores was made for all students, as well as for all females and for all males. The results indicated that the experimental group, compared to the control group, had significantly higher mean scores on tests of attitudes toward science, perceptions of science, extracurricular science activities, and interest in a science-related career.  相似文献

A modified Stroop Test (single-letter, letter-cluster, and whole-word colorinconsistent stimuli) showed greater interference for the more automatic orthographic coding unit—the word—than for the less automatic coding units—single letters and letter-clusters—in developing readers in second, fourth, and sixth grade (N=72, Study 1). A developmental trend was observed from relative skill in word-level orthographic-phonological correspondence in second graders to relative skill in subword level orthographic-phonological correspondences in sixth graders. A previous finding that whole word coding > letter coding > letter cluster coding in relative rate of development was replicated (N=300, Study 2). Multiple orthographic codes—for whole words, single letters, and letter clusters—were correlated with both reading and writing but patterns of correlations with the component reading and writing skills changed from first to third grade; by third grade whole word coding was not correlated with reading and writing skills but letter cluster coding was correlated with all reading and most writing skills. Cue validity —categorization of letters on the basis of differentiating rather than distinctive features—improved from second to sixth grade and may account for developmental gains in letter cluster coding. Level of cue validity was correlated with speed of sentence comprehension (N=60, Study 3). The theoretical and practical significance of multiple orthographic codes for orthographic-phonological connections in word recognition and for literacy acquisition in general is discussed.This research was supported, in part, by Grant No. 25858-01 awarded to the first author from the National Institute of Child Health and Human Development.Study 1 is based on a presentation at the 1990 meeting of the American Education Research Association.

This exploratory study sought to determine the strategies used by programs accredited by the Council for Accreditation of Counseling and Related Educational Programs (CACREP) to recruit and retain ethnic minority faculty. Seventy‐three CACREP liaisons were surveyed, and the results indicated that many programs have not developed specific strategies to recruit and retain ethnic minority faculty. Mentoring was the most frequently reported strategy for retaining ethnic minority faculty. Implications for counselor education are discussed.  相似文献

Conclusion While career plateauing is a major challenge facing contemporary organizations, possible solutions are available. The career development specialist possessing a variety of skills geared toward both proaction and reaction can be instrumental in designing interventions which minimize the negative impact of plateauing. While career plateauing can be a devastating problem for many high achieving, self-sacrificing baby boomers, for others it may present an opportunity to escape the internal pressures for success. Much of what happens to a plateaued employee is determined by the resources possessed by the employee as well as the organization's response to the employee. The activities of the career development specialist constitute much of what is considered the organization's response. A career plateau may mark the beginning of a period characterized by frustration and depression or it may present the opportunity for a new challenge or reappraisal of life direction and goals.  相似文献

In Greek mythology, the Chimera is a fire-breathing monster with three heads: one of a lion, one of a horned goat, and one of a powerful dragon. Of similar construction is the presence of three structures in US society, whiteness, patriarchy, and capitalism, which are overwhelmingly represented, valued, and espoused when examining areas of progress, i.e., family income, poverty rates, high school and college graduation rates, and home ownership. This modern American three-headed beast controls, manipulates, and permeates all aspects of US society irrespective of class, culture, or gender. Using critical race theory and critical whiteness studies, this critically interpretive parable draws from the ways in which whiteness, patriarchy, and capitalism function in social, cultural, economic, and educational spheres. The parable tells the story of Sue Libertad and analyzes how this metaphorical Chimera, despite its ubiquity, silently permeates all aspects of her life. Not until a tragic outbreak occurs, does the hegemony of this chimera erodes and Sue.  相似文献

Children's conflict management in three close relationships was studied longitudinally in 38 second born children, observed at home with their mothers and siblings at 33 months and at 47 months, and with friends at 47 months. Children used significantly more other-oriented argument with friends than with their mothers or siblings. Their use of reasoned argument with their siblings, but not their mothers, was related to their emotional understanding assessed formally at 40 months. The emotional context of conflict interactions was found to be important as an influence on children's use of reasoned argument, with less reasoning shown by children when they were upset at 33 months. The differences in patterns over time and in links with emotional understanding for these different relationships is discussed, and the significance of child-child interaction in the development of social understanding is highlighted.  相似文献

This study examined age differences in young people's understanding of evolution theory in secondary school. A second aim of this study was to propose a new coding scheme that more accurately described students’ conceptual understanding about evolutionary theory. We argue that coding schemes adopted in previous research may have overestimated students’ grasp of evolutionary concepts. A total of 106 students aged 12, 14, and 16 took part in individual interviews investigating their understanding of evolution. Using the new coding scheme, we found that while 16‐year olds were more likely than 12‐year olds to endorse scientific concepts when answering a question about finches, their understanding of natural selection, however, did not generalize to the other four questions. Furthermore, students began to incorporate relevant terminology (e.g., adapt, evolve, etc.) and structure their explanations using relevant language at around age 14. Students often used relevant terminology without having a more advanced understanding of evolutionary theory. Instead, they used the relevant terms in a colloquial rather than a scientific sense. Implications of the current findings for teaching and theory are discussed. © 2016 The Authors.

In Experiment 1, hungry rats received 30 rewarded runway trials and then either extinction trials followed by retention tests or just retention tests. Different groups were tested after retention intervals of 1 min, 1, 3, or 24 h, or 30 days. Retention of extinction training was a nonmonotonic, cubic function of time for the early portion of the response chain, with good retention at 1 min and 3 h and little retention at 1 h, 24 h, or 30 days. In the latter portions of the response chain, retention of extinction decreased monotonically with time. Retention following reward-only training varied little in time, though slight losses occurred after 30 days. Experiments 2–3 differed from Experiment 1 in imposing nonchoice discrimination training (reward vs. nonreward) instead of extinction following 30 rewarded trials. After different time intervals (.017, .75, 1.25, 3, and 24 h in Experiment 1; and .017, 1, and 3 h in Experiment 2), retention tests revealed poorest discrimination at intermediate intervals in the initial portion of the response chain, i.e., a Kamin effect appeared. The deficit seemed the result of a loss of response suppression to the cue that signaled nonreward. In latter segments of the response chain, a Kamin effect tended not to appear. Implications for a number of observations and theoretical views are noted.  相似文献
