Institutions of higher education place high priority on ensuring that their faculties are adequately paid. Since gauging the adequacy of compensation is a problem of relative measure, this assessment is usually performed by comparing university-level average salaries for a group of peer institutions. Often the potential distortions caused by differences in the rank mix of the faculty are forestalled by comparing average salaries for each of the four ranks. However, few if any institutions take similar steps to prevent the skewing of averages owing to differences in cost of living, differences in distribution of faculty in academic year and twelve-month appointments, and differences in the configuration of the faculty over disciplines. This paper shows that salary comparisons that do not compensate for these variation in staff mix are seriously flawed. A recommended methodology is demonstrated. 相似文献
High levels of student absenteeism, low SES home environments, and a general lack of experienced teachers to service the school curriculum all contribute to difficulties in insuring the delivery of apriori school district defined instructional programs. The importance of urban school site educational evaluation is underscored by recent studies which show that the effectiveness of instructional delivery is an important predictor of student antisocial behavior such as drug abuse, gang activity, vandalism. This study examines some of the problems associated with instructional evaluation in urban school settings using signal-receptor assessment theory analysis and a new type of test scoring procedure called Modified Confidence Weighted-Admissible Probability Measurement (MCW-APM). With MCW-APM, school administrative personnel can simultaneously evaluate and obtain policy relevant information for instructional leadership concerning the signal (instruction as delivered), the reception (student learning as received), and the assessment instrumentation itself (sensitivity of the test). Additionally, this method of scoring permits individual student performance on school district developed CRTs to be referenced to an information based standard (informed, partially informed, uninformed, and misinformed) of mastery as a selection standard instead of a percent correct score. 相似文献
Weanling rats were tested for retention of an aversion to a novel flavor (chocolate milk) that had been conditioned as a single-element conditioned stimulus (CS) or in compound with a novel ambient odor (banana). The presence of the ambient odor during conditioning had no effect on flavor aversion shortly thereafter, confirming previous results. The flavor aversion observed 21 days after conditioning, however, was significantly stronger for pups conditioned with the single-element CS than for those given the flavor-odor compound as the CS. This retention effect was due to a surprisingincrease in the conditioned aversion observed 21 days after conditioning with the single-element CS. A second experiment confirmed this paradoxical increase in retention of the aversion to chocolate milk. This experiment also verified that no such increase occurred in retention of the conditioned aversion to a different flavor (saccharin), whether the initial aversion was strong or weak. The results may be explained in terms of generalized latent inhibition from consumption of mother’s milk. 相似文献
Pigeons were trained to match-to-sample with several new methodologies: a large number of stimuli, computer-drawn color picture stimuli, responses monitored by a computer touch screen, stimuli presented horizontally from the floor, and grain reinforcement delivered onto the picture stimuli. Following acquisition, matching-to-sample concept learning was assessed by transfer to novel stimuli on the first exposure to pairs of novel stimuli. One group (trial-unique), trained with 152 different pictures presented once daily, showed excellent transfer (80% correct). Transfer and baseline performances were equivalent, indicating that the matching-to-sample concept had been learned. A second group (2-stimulus), trained with only two different pictures, showed no evidence of transfer. These results are discussed in terms of the effect of numbers of exemplars on previous failures to find concept learning in pigeons, and the implications of the positive finding from this experiment on abstract concept learning and evolutionary cognitive development. 相似文献
The first part of the article provides a historical account of the broad phases of development that educational television has passed through as a result of social and technological influences:
its beginnings in broadcasting in the fifties and sixties;
its development through the video age in the seventies and eighties, with widening scope and opportunity as a result of developments in production and reception/recording equipment and an expansion of communication channels;
its present potential, at the dawn of the interactive age, as a result of the influences of new technology.
The article then examines the problems of integrating new television‐related technologies into the educational system and draws attention to:
the frequent past failures of the educational system to fully exploit new technologies, resulting in superficial integration and ineffectual use;
the current tensions between the traditional educational technology approach and the drives behind much new technology;
the need for appropriate systems and structures to ensure that the evaluation of such new technologies is properly resourced and effectively carried out.
