While much is known about faculty time allocation, we know very little about how traditional managerial factors influence faculty time allocation behaviors. We know even less about the possible downsides associated with relying on these traditional managerial factors. Using survey data from the National Science Foundation/Department of Energy Survey of Academic Researchers, our study predicts faculty time allocations to grant writing as a function of pressure from administrative superiors. We then examine how pressure from administrative superiors influences faculty job satisfaction and the likelihood to pursue uninteresting research grants. Our findings indicate that faculty time spent pursuing grants increases in response to pressure from administrative superiors but that this same pressure is associated also associated with increases in pursuit of uninteresting research grants as well as decreases in work satisfaction. Our study contributes to better understanding of the merits and limitations of traditional, hierarchical approaches to managing university faculty behavior.  相似文献

To This is a 1 test per thousand learn more about normal language development in deaf children, we have developed the MacArthur Communicative Development Inventory for American Sign Language (ASL-CDI), a parent report that measures early sign production. The ASL-CDI is an inventory of sign glosses organized into semantic categories targeted to assess sign language skills in children ages 8 to 36 months. The ASL-CDI uses a recognition format in which parents check off signs that their child produces. The form has demonstrated excellent reliability and validity. To date, normative data have been collected from 69 deaf children with deaf parents who are learning sign language as a first language. We discuss the development of the ASl-CDI and preliminary cross-sectional and longitudinal findings from this early data collection with particular focus on parallels with spoken language acquisition. We also discuss the acquisition of first signs, negation, wh-questions, and fingerspelling with developmental patterns provided based on age, as well as vocabulary size.  相似文献

Abstract

We identified 48 barriers to teaching environmental education reported by teachers in global literature and compared frequency to empirical data we collected from rural Ecuador, part of an understudied region and continent. We utilized Q methodology and interviews with 25 (78%) teachers at 6 schools to identify and categorize barriers. Perceptions of barriers ranked by Ecuadorian teachers were statistically classified into three factors: logistical (associated with fieldtrips, time, and money); training and lack of government support; and attitudinal (associated with student disinterest). In contrast, barriers related to student testing and controversial topics were only reported in more developed countries. Results enable region-specific recommendations.  相似文献

Portfolios can serve as a means of collecting information that can be seen as evidence for evaluating the achievement of students in classrooms. The use of portfolios has a long history although their general use in classroom assessment is a recent phenomenon. Portfolios are not widely used in large‐scale assessments; they are a classroom‐based phenomenon in Canadian schools. In this paper, we explore three themes related to portfolio use in the Canadian context. First, we consider examples of policies and procedures as recommended by Ministries of Education to illustrate the range of statements provided. Next, we review surveys of portfolio use and acceptance by teachers and, to a lesser degree, administrators. Finally, we describe and discuss three studies that have begun to investigate the use and interpretation of portfolios.  相似文献

As instructional design professionals are being asked more frequently to develop interventions for global environments, they must account for many complex intercultural communication and corporate globalization strategy variables. Simple rules of etiquette and stereotypes about particular cultures are tempting but dangerous assumptions upon which to base the design and delivery of training for multicultural learners. On the other hand, a full understanding of the subtle cultural differences that could impact global training is beyond the expectations to which instructional designers could reasonably be held. A more sensible approach than trying to know all the answers is knowing what questions to ask in the needs analysis and assessment phases. Based on a synthesis of literature and instantiated by several short examples, a framework for identifying important issues for instructional design and delivery in global settings is presented.  相似文献

Two theories of assessing function knowledge were compared for intuitive physics. The choice assessment theory, derived from Piaget, presents subjects with two physical situations, each specified by the values of two physical variables; subjects choose the situation which will yield the greater value of a dependent variable. Functional measurement presents subjects with a single physical situation; subjects make a quantitative estimate of the dependent variable. Forty subjects made both choice and functional measurement responses for two situations of intuitive physics. The choice theory showed substantial frequencies of stepwise rules, implying that subjects failed to integrate the two given physical variables. Functional measurement, in contrast, showed that most subjects integrated the two variables, following exact addition or multiplication rules. It is concluded that functional measurement gives a more correct assessment of function knowledge and should be useful in science instruction. J Res Sci Teach 34: 359–376, 1997.  相似文献

Abstract James Perry Wilson transformed the subjective methodology of diorama background painting into a more objective practice by replacing an emotional and interpretive model with one based on the science of optics and other supportable references. He also succeeded in creating an overall mood in each of his diorama paintings. This article documents the step by step process of Wilson's methods. Wilson's two methods for documenting the site chosen for the diorama were: a plein air field painting, and panoramic photographs. At the museum, he created a complete scale model of the diorama and its background, accurate in all aspects, though miniature. On the full‐scale diorama background, a charcoal underdrawing preceded the painting. The sky was painted first, next the horizon, then the mid‐range distances, and finally the foreground. Each stage increased in colorvalue contrast and in resolution of detail. Wilson's mastery is most evident in the “tie‐up,” where the painted background meets the three‐dimensional foreground.  相似文献

This case study illustrates instruction in an urban 6th‐grade classroom in which students were learning about mass, volume, and density by attempting to layer (stack) three miscible solutions with differing densities atop one another. The study examines classroom discourse and interaction on the basis of four teaching goals: (a) reaching consensus about which stacks were possible, (b) developing persuasive arguments that separated data from noise, (c) establishing social norms for collective inquiry, and (d) appreciating the epistemological status of scientific knowledge. The study traces the fate of three stacks that students claimed were possible after initial investigations with the solutions. These claims underwent a process of collective validation in which consensus without coercion was the goal, which illustrates emergent standards for backing claims with evidence, as well as for replicability, among the students. Students were successful in achieving three of the four goals, with some qualifications. In relation to Goal 3, which required generalization to other situations, somewhat less success is reported. Limitations in the current standards, difficulties of time allotment in current curricula, and establishing classroom cultures of inquiry are discussed. © 1999 John Wiley & Sons, Inc.
