This study was designed to obtain the perceptions of regular class teachers who taught children who had been in EMR programs, but had been decertified (D) and returned to regular classes in response to court cases and recent legislation. A cohort of regular class (RC) students were selected for comparative purposes. It was found that D students were placed into low ability classes; yet, teachers perceived D subjects to be significantly lower than RC students in both academic achievement and social acceptance. Only a small proportion of teachers indicated that the enrollment of D students had much impact on the regular class instructional program. However, the teachers were rather critical of the services received under the auspices of a transitional program, indicating in large part that the services were either not apparent or ineffective.  相似文献

The WISC-R scores for groups of children identified by school personnel as needing special education services were factor analyzed according to type of classification. WISC-R factor loadings were obtained for the scores of children labeled Learning Disabled, Educable Mentally Impaired, and Emotionally Impaired, as well as groups labeled Other and None. Overall, results show the WISC-R to be factorially similar for all groups, with two principal factors emerging which correspond to the Verbal-Performance structure of the test. Significance tests among mean scale scores and IQ scores yielded few meaningful differences across groups.  相似文献

The Odd Couple…” is a narrative presentation of the successful joint programming efforts of a public school system and community centers for mental health in providing comprehensive educational services to emotionally disturbed students. Problems and resolutions in regard to control, coordination, and philosophy issues are discussed. This article describes a simple yet effective model for cost effective and successful joint programs between non-administratively related agencies.  相似文献

Educators are expressing concern over the wide and growing gap which they perceive to exist between research and practice in our nation's schools. A review of the literature reveals that this important, long-standing concern is well founded. It is proposed that the school psychologist with his/her specialized training in research theory and methodology and unique role as a practitioner in the school setting is the ideal professional to effect a linking of formal knowledge to educational practice. Presumably, the provision of such a vitally needed function will serve to enhance school psychologists' often less than favorable image with their educator colleagues. A paradigm is offered for effecting research into practice utilizing the school psychologist in the role of knowledge-linker.  相似文献

Biodiversity science in China has seen rapid growth over recent decades, ranging from baseline biodiversity studies to understanding the processes behind evolution across dynamic regions such as the Qinghai-Tibetan Plateau. We review research, including species catalogues; biodiversity monitoring; the origins, distributions, maintenance and threats to biodiversity; biodiversity-related ecosystem function and services; and species and ecosystems’ responses to global change. Next, we identify priority topics and offer suggestions and priorities for future biodiversity research in China. These priorities include (i) the ecology and biogeography of the Qinghai-Tibetan Plateau and surrounding mountains, and that of subtropical and tropical forests across China; (ii) marine and inland aquatic biodiversity; and (iii) effective conservation and management to identify and maintain synergies between biodiversity and socio-economic development to fulfil China''s vision for becoming an ecological civilization. In addition, we propose three future strategies: (i) translate advanced biodiversity science into practice for biodiversity conservation; (ii) strengthen capacity building and application of advanced technologies, including high-throughput sequencing, genomics and remote sensing; and (iii) strengthen and expand international collaborations. Based on the recent rapid progress of biodiversity research, China is well positioned to become a global leader in biodiversity research in the near future.  相似文献

Though there is a long tradition of band members quitting the group or taking a hiatus, the rock group as an organization to produce music continues to be both popular and economically viable. The research question addressed in this paper is whether or not it is a good idea to quit or take a hiatus from the group. We begin with a discussion of the framework for understanding why groups are formed and why they may be difficult to keep together. We then discuss differences between groups in the decade of the 1960s versus today. We argue that there is something unique about the output of the group even with the changes in the structure of contracts, compensation, and consumer focus on the artist that explain the resilience of the rock band as an organizational form within which to create music. We compare the charting success of bands that have members leave the group with the charting success of the members who left the group. We identified the groups in five representative years: 1965, 1975, 1985, 1995, and 2005. We then analyzed the entire Billboard Hot 100 charting careers of those groups and the artists who quit those groups. Our main finding is that when charting success is divided equally among members, going solo pays off—there is a clear economic rationale because solo acts have greater average charting success than the original bands they started in. The other ensuing side projects: duos, collaborations, and other groups are not as lucrative as the original bands. These findings are valid for members of charting groups from each of the 5 years examined. Despite the difficulties in keeping a rock band together, there are fewer band breakups today and remaining with the group generally results in a longer and more productive charting career. Thus, the rock group remains an important organization for producing contemporary music. However, there remains a compelling incentive to go solo. Superstars may benefit from solo projects, but for the average, non-superstar group member, in many circumstances it is better for the band to stay together if the income is divided equally.  相似文献

This study investigated the combined role of instructor communication variables (nonverbal immediacy and self-disclosure), instructor credibility (competence, caring, and trustworthiness), and student personality traits (extraversion, neuroticism, agreeableness, conscientiousness, and openness) in predicting students’ uncivil behaviors in class. A total of 406 students completed online questionnaires regarding the instructor of the class they attended prior to the one in which the study was administered. Personality and instructor behavior variables contributed approximately equally to explaining variance in student incivility. Students’ conscientiousness and agreeableness had direct negative relationships with incivility, whereas instructors’ amount and negativity of self-disclosure had direct positive relationships with incivility.  相似文献
