This study reports on an investigation of students' understanding of the concept of weightlessness among intermediate, high
school and college students. It appears possible to interpret this knowledge as being highly influenced by the confusion between
two basic physics concepts, weight and gravitational force, which are often equated in a standard physics curriculum. The
proposed causal structure of students' knowledge presents a platform for interpreting a cluster of students' alternative ideas
about weight and related physical concepts. This platform could guide physics educators in their considerations of appropriate
strategies for presenting weight and gravity topics in the classroom. 相似文献

Feedback is a key concern for higher education practitioners, yet there is little evidence concerning the aspects of assessment feedback information that higher education students prioritise when their lecturers’ time and resources are stretched. One recent study found that, in such circumstances, students actually perceive feedback information itself as a luxury rather than a necessity. We first re-examined that finding by asking undergraduates to ‘purchase’ characteristics to create the ideal lecturer, using budgets of differing sizes to distinguish necessities from luxuries. Contrary to the earlier research, students in fact considered good feedback information the single biggest necessity for lecturers to demonstrate. In a second study, we used the same method to examine the characteristics of feedback information that students value most. Here, the most important perceived necessity was guidance on improvement of skills. In both studies, students’ priorities were influenced by their individual approaches to learning. These findings permit a more pragmatic approach to building student satisfaction in spite of growing expectations and demands. 相似文献

Superintendents and school board presidents from the 100 largest school districts in the nation were surveyed to determine the major problems confronting these education leaders. Both superintendents and school board presidents were in agreement on most concerns, including the top three major problems. They are in complete agreement that finance and related worries are the most important problems they face. The survey identified several critical variables, including the superintendents' age, gender, and experience; the school board presidents' gender and experience; and the school districts' size, geographical region, metropolitan setting, and ethnic student profile. 相似文献

One of the main goals of science education is the development of scientific investigation skills (Bryce & Robertson, 1985;
Woolnough & Allsop, 1985). This paper describes a practical test instrument developed to assess students’ attainment of skills
associated with problem analysis and planning experiments, collecting information, organizing and interpreting information,
and concluding. During administration of the test, students verbalized their thoughts as they worked on the task and their
performance was videotaped for analysis. Preliminary results reveal important areas of student weakness and lead to recommendations
for curriculum reform.

In the fall of 1969, a program to expand educational opportunities (EEO) for economically disadvantaged students was initiated at Macalester College. During the first three years of the program, the percentage of non-white students at the College rose from 3% to approximately 15%.Average grades for the EEO students were approximately one standard deviation below those of a random non-EEO sample, similar to the differences in high school grades between the two groups. However, the EEO students persisted at Macalester College at a slightly higher rate than non-EEO students. The EEO students also were more likely than non-EEO students to major in the behavioral/social sciences and less likely to major in the fine arts, humanities, and physical sciences. 相似文献

Visual displays such as graphs have played an instrumental role in psychology. One discipline relies almost exclusively on graphs in both applied and basic settings, behavior analysis. The most common graphic used in behavior analysis falls under the category of time series. The line graph represents the most frequently used display for visual analysis and subsequent interpretation and communication of experimental findings. Behavior analysis, like the rest of psychology, has opted to use non-standard line graphs. Therefore, the degree to which graphical quality occurs remains unknown. The current article surveys the essential structure and quality features of line graphs in behavioral journals. Four thousand three hundred and thirteen graphs from 11 journals served as the sample. Results of the survey indicate a high degree of deviation from standards of graph construction and proper labeling. A discussion of the problems associated with graphing errors, future directions for graphing in the field of behavior analysis, and the need for standards adopted for line graphs follows. 相似文献

Concern is increasingly being expressed about the teaching of higher order thinking skills in schools and the levels of understanding
of scientific concepts by students. Metaphors for the improvement of science education have included science as exploration
and science as process skills for experimentation. As a result of a series of studies on how children relate evidence to their
theories or beliefs, Kuhn (1993a) has suggested that changing the metaphor to science as argument may be a fruitful way to
increase the development of higher order thinking skills and understanding in science instruction. This report is of a case
study into the coordination of evidence and theories by a grade 7 primary school student. This student was not able to coordinate
these elements in a way that would enable her to rationally consider evidence in relation to her theories. It appeared that
the thinking skills associated with science as argument were similar for her in different domains of knowledge and context.

The demand for higher education facing an individual institution 总被引:1,自引:0,他引:1
The purpose of this paper is to provide an estimate of the elasticity and cros-selasticities of demand for higher education facing an individual institution. The utility which a high school graduate derives from each educational option open to him is assumed to be a stochastic function of the attributes of that option. For certain types of utility functions the maximization of utility results in the logit probability model. This model is used to analyze the choices made by a sample of high school graduates in Hawaii. Estimates of the price elasticity and the cross-price elasticities of demand for enrollment at the University of Hawaii are obtained. It is found that the demand is quite inelastic with respect to both tuition and total cost of education. These estimates imply that changes in tuition will not affect enrollment appreciably.The authors wish to express their appreciation to Arthur S. Goldberger, H. Laurence Miller, and Pan A. Yotopoulos for their comments on earlier drafts of the paper. 相似文献
