This article addresses problems facing universities because of external pressures for changes in their teaching, research, and governance and management policies and practices to align them with public policies. The view is put that governments are introducing public policies in times of economic recession to achieve rationalisation of human, physical and financial resources in higher education and to foster initiatives that shape university teaching and research to serve the needs of society and assist in national economic recovery. Examples of these external pressures, which have resulted in intrusions into the autonomy of university governance and management, are provided in the context of general system theory. It is assumed that the pressure of public policies on universities will continue and that each university should have a development plan for its present and future teaching and research activities, which has the endorsement of the government higher education advisory agency so that university management can function on a secure basis. The effectiveness and efficiency of functioning at the various levels of the university system should be assessed by periodic evaluative reviews. The quality of management by academic leaders should be fostered by the establishment of national centres for the study of higher education management and policy. The relationship between government higher education advisory agencies and universities should be renegotiated so that, as interdependent and interrelated parts of the higher education system, they work in joint co-operation to ensure the most effective and appropriate development of each institution. Nevertheless, a state of equilibrium between the university system and the supra (social) system within which it exists will never fully be achieved. The fundamental role and functions of a university require that it be concerned with teaching and researching both ageless and current phenomena. Hence, a perfect equilibrium state cannot exist if external social pressures are for the main weight of university activities to be shifted to providing service for the current needs of society. 相似文献

In an exploratory study, education majors in a physical science course were given a set of tasks analogous to a given, solved prototype-task to see how transfer items were handled. Some students were given a conceptual model along with the solved prototype. Others were given a general procedure for applying the conceptual model to the transfer items. The procedure helped considerably for the transfer items least like the prototype item. The model alone was also effective for certain items. In the absence of both model and procedure, students' problem solving was usually incoherent or self-contradictory. Presenting additional solved items helped marginally on an exceptionally novel item. Students' main source of difficulty, given the model and procedure, was that they were distracted by prior, concrete experience and thus failed to follow the procedure. For most students, this difficulty could readily be overcome. A small proportion (10–15%) of students had more profound difficulties. 相似文献

This study examined children's motivation in elementary physical education within an expectancy-value model developed by Eccles and her colleagues. Four hundred fourteen students in second and fourth grades completed questionnaires assessing their expectancy-related beliefs, subjective task values, and intention for future participation in physical education. Results indicated that expectancy-related beliefs and subjective task values were clearly distinguishable from one another across physical education and throwing. The two constructs were related to each other positively. Children's intention for future participation in physical education was positively associated with their subjective task values and/or expectancy-related beliefs. Younger children had higher motivation for learning in physical education than older children. Gender differences emerged and the findings provided empirical evidence supporting the validity of the expectancy-value model in elementary physical education. 相似文献

Achievement goal theory and the expectancy-value model of achievement choice were used to examine fourth-grade students' motivational changes in an elementary physical education running program. In fall and spring of the school year, participants (N = 113; 66 boys, 47 girls) completed questionnaires assessing achievement goals, expectancy beliefs, subjective task values, and intention for future running participation. They also completed a timed 1-mile (1.6 km) run. The number of laps they ran/walked during the school year was used to assess students' persistence/effort. Results indicated the students improved their run but became less motivated about running while participating in a year-long running program. Children's beliefs about how good they were in the running program (i.e., expectancy beliefs) and their perceptions of how interesting and fun it was (i.e., interest) emerged as the strongest positive predictors of their motivation for running over time. These findings provide strong empirical evidence that expectancy beliefs and interest are essential to children's motivation in elementary physical education. 相似文献

A content analysis of children’s television examined the frequency with which behaviors were (a) driven by altruistic versus egoistic motivations, (b) performed by affable/surly characters, (c) rewarded/punished, and (d) present in content popular among different age groups (2–5, 6–11, and 12–17 years old). We found that portrayal patterns stressed the importance of egoistic motivations (particularly competence, autonomy, and relatedness) for older children. The findings are interpreted in line with logic underlying the model of intuitive morality and exemplars (MIME; Tamborini, 2013), suggesting that media representations can influence the motivations of their viewers. 相似文献

This study sought to determine if exposure to two communication-oriented activities, videotapes and public service announcements, accounts for changes in substance use among adolescents participating in the Drug Resistance Strategies Project's keepin' it REAL adolescent substance use prevention curriculum. Middle-school students (4,734, 72% Latino) responded to questionnaires related to these analyses. An analysis of covariance (ANCOVA) model was fit separately to six substance use outcomes. The results suggested that intervention students who saw four or five videos engaged in less substance use in the past month than did students who saw fewer videos. Having seen the PSAs one or more times did not predict the reported change in substance use. 相似文献
