Chairmen at 38 state and land-grant institutions were found to be involved in three major roles: academic, administrative, and leadership. The academic role consists of duties of student involvement and research activities. Chairmen enjoy this role and report high emphasis on concurrent goals but feel frustrated in terms of time to pursue commensurate activities. The administrative role requires the majority of time and also contains some of the less desirable duties. In addition, administrative goals are seen as over-emphasized. The leadership role involves tasks related to academic personnel and program development. It is a major satisfaction realized by accepting the position of chairman. Developing abilities of faculty members and maintaining academic freedom are the two most important goals in this role. The respondents also made suggestions on changes and development programs which would improve their effectiveness.  相似文献

This paper attempts a theoretically based articulation of the concept of legitimacy and applies the elements of the concept to concrete problems in university governance. Legitimacy is measured by the assessment of several elements of governance by constituents. It is a function of constituents' value systems, of the decision-making issue, and of the level at which decisions are made. The components of legitimacy are developed, and illustrative applications are provided. Through operational application of the idea of political legitimacy, it is contended that more realistic and workable solutions to governance can be approximated and that crisis oriented governance tactics can be reserved for situations which genuinely require them.  相似文献

Abstract

Experiential learning theory places experience at the center of learning. Kolb’s four-stage cycle of experiential learning suggests that effective learners must engage fully in each stage of the cycle – feeling, reflection, thinking, and action. This research assesses the alignment of Kolb’s experiential learning cycle with the week-long Summer Institute of Assisting, Collaborating, and Training ESL Secondary Content Teachers (ACT-ESL), the first stage of a professional development model designed to train content teachers of English Language Learners (ELLs). Qualitative and quantitative data analysis from pre- and post-surveys determined positive changes in participants’ understanding of key ELL concepts, knowledge, and understanding of instructional strategies and practices. Analysis indicated that the Summer Institute had a large effect (d > 2.00 for each scale), regardless of previous training in ELL instructional strategies. Findings show that the Summer Institute incorporated the cycle of learning and tenets of Kolb’s experiential learning theory and evidenced teacher learning.  相似文献

In consideration of the potential of drawing and writing as assessment and learning tools, we explored how early primary students used these modes to communicate their science understandings. The context for this study was a curricular unit that incorporated multiple modes of representation in both the presentation of information and production of student understanding with a focus on the structure and function of carnivorous plants (CPs). Two science teacher educators and two first-grade teachers in the United States co-planned and co-taught a multimodal science unit on CP structure and function that included multiple representations of Venus flytraps (VFTs): physical specimens, photographs, videos, text, and discussions. Pre- and post-assessment student drawings and writings were statistically compared to note significant changes, and pre- and post-assessment writings were qualitatively analysed to note themes in student ideas. Results indicate that students increased their knowledge of VFT structure and function and synthesised information from multiple modes. While students included more structures of the VFT in their drawings, they were better able to describe the functions of structures in their writings. These results suggest the benefits for student learning and assessment of having early primary students represent their science understandings in multiple modes.  相似文献

Members of this research team are investigating the use of multipoint desktop video conferencing (MDVC) technology in Singapore to enhance the National Institute of Education's schools practicum partnership model. The project builds on the Singapore ONE ATM island-wide network and the high-speed ADSL line access provided by Singtel Magix. This infrastructure provides state-of-the-art support for the White Pine CU-SeeMe Meeting Point server and client software that enables students on teaching practice to conference with each other and their university-based supervisors. A typical conference involves four of five students at different schools and one staff member at the National Institute of Education in Singapore. These conferences provide opportunities for professional sharing between staff and students without the limits of time and space which are traditional constraints on conventional teaching practice.  相似文献

Three substudies of effects of different formats on student ratings of faculty teaching effectiveness were conducted. One substudy, Kinds of Keys, investigated three main kinds of keys: Agreement, Evaluation, and Needs Improvement. The second, NO TUP, investigated numbers of positive rating categories. The third, Item Wording Direction, investigated the same items worded positively, negatively, and neutrally, respectively. Practically important differences in level of ratings obtained in Kinds of Keys and practically and statistically significant differences obtained in NO TUP and Item Wording Direction. It was concluded that additional research is necessary to determine if apparent differences in teaching effectiveness are actually differences in teaching effectiveness or differences due to the methods of measurement.  相似文献

This study examined the feeling state content of 3- and 4-year-olds' narratives. Four times throughout the school year, each child was paired with a familiar adult and provided an opportunity to talk with the adult about his/her day. Children's narratives were then coded for their feeling state content. Results revealed that children talk a great deal about affiliation, that sex differences emerge only in the context of interactive talk between adults and children, and that older children talk more about emotions than younger children when speaking spontaneously, but that these differences disappear when adults are able to provide “scaffolding” to the younger, less experienced, children.  相似文献

OBJECTIVE: To determine factors influencing outpatient mental health service use by children in foster care. METHOD: Detailed survey and administrative data were collected on 480 children who entered long-term foster care in San Diego County from May 1990 through October 1991. These data were linked with claims data from Medicaid and San Diego County Mental Health Services information systems. A Poisson regression model was used to determine whether the following factors influenced outpatient mental health service use: age, race/ethnicity, gender, maltreatment history, placement pattern, and behavioral problems as measured by the Achenbach Child Behavior Checklist (CBCL). RESULTS: Except for maltreatment history, all independent variables included in the multivariate regression model were statistically significant. The total number of outpatient mental health visits increased with age, male gender, and non-relative foster placements. Relative to Caucasians, visits were lower for Latinos, and Asian/Others, but comparable for African-Americans. Concerning maltreatment history, differences were only found in one category; children experiencing caretaker absence received fewer visits compared to children who did not experience caretaker absence. Children with CBCL Total Problem Scale T-scores of 60 or greater had significantly more visits than those with a score less than 60. CONCLUSIONS: Both clinical and non-clinical factors influence outpatient mental health service use by foster children. Limitations imposed by gender, race/ethnicity, and placement setting need to be addressed by child welfare policies. These finding suggest that guidelines are needed to systematically link children in foster care with behavioral problems to appropriate services.  相似文献

This study compares the impact of Anglican voluntary aided and voluntary controlled schools on a range of indices of local church life throughout the diocese of Chelmsford. After controlling for the influence of population size, the church electoral roll, the age of the priest in charge of the benefice, the number of churches in the benefice, and the number of stipendiary clergy employed in the benefice, the data lead to two conclusions. Voluntary controlled primary schools have no significant impact on any of the indices of local church life included in the study. Voluntary aided primary schools are associated with a significantly higher level of pre-teenage confirmands, but they have no influence on the number of older confirmands, the number of baptisms, the usual Sunday church attendance, or the number of festival communicants.  相似文献
