Despite a persistent belief to the contrary, most Canadian universities prior to the 1960s did not operate collegially. They were run autocratically. Collective bargaining arose as a means of ensuring true collegiality through negotiations between equals, legally entrenching due process and academic freedom, and providing a clearer and stronger mechanism for dealing with salaries and benefits. This was a revolution from below in the governance of universities. Although the sixties are widely regarded as the age of student revolt, in Canada it was the faculty, not the students, who secured a dramatic change in the power structure of the university through collective bargaining. 相似文献

Rats were trained in a two-lever operant chamber to discriminate the presence versus the absence of a drug. During drug sessions, the training procedure involved reinforcing presses on lever 1 with saccharin-sweetened water but not reinforcing presses on lever 2. During no-drug sessions, only presses on lever 2 were reinforced. After this discrimination was learned, each rat was trained to discriminate presence versus absence of a second drug. All rats learned this second discrimination. Finally, the rats were tested to determine whether they could still discriminate the first drug, as well as other pharmacologically related compounds; most rats could. Training drugs were phenobarbital 30–35, nicotine 0.4, amphetamine 0.4, cyproheptadine 7, phencyclidine 4, cyclazocine 1.5, fentanyl 0.04, and scopolamine 0.2 mg/kg. The results indicate that drug versus no-drug discrimination training does not disrupt discriminative control previously established with a different drug. When considered in combination with the results obtained during substitution tests conducted after drug-versus-no-drug training, the data suggest that, instead of discriminating drug cues versus no-drug cues, rats discriminate presence versus absence of particular drug cues. 相似文献

The authors used a pretest-posttest control group design with random assignment to evaluate whether early reading failure decreases children's motivation to practice reading. First, they investigated whether 60 first-grade children would report substantially different levels of interest in reading as a function of their relative success or failure in learning to read. Second, they evaluated whether increasing the word reading ability of 15 at-risk children would lead to gains in their motivation to read. Multivariate analyses of variance suggest marked differences in both motivation and reading practice between skilled and unskilled readers. However, bolstering at-risk children's word reading ability did not yield evidence of a causal relationship between early reading failure and decreased motivation to engage in reading activities. Instead, hierarchical regression analyses indicate a covarying relationship among early reading failure, poor motivation, and avoidance of reading. 相似文献

In the latest in a series of articles on experimental courses at Kent State University, the authors study how students perceive such classes in terms of a liberal arts cultural education versus a values oriented education. The results determine that subject matter interest was the prime motivation for students to enroll in experimental classes. The results also suggest an openness and variety of student interest that seems unaware of a liberal arts core of the best that has been thought. 相似文献

Indonesia, like many developing countries, has problems of increasing numbers of students, shortage of qualified teachers, limited resources and strong support for traditional schooling. Educational technology has been introduced to help alleviate some of the problems and has been relatively successful over the past 15 years. A planned effort to use educational technology in appropriate ways began in the mid-1970s and is still growing. Such success does not come easily. The lessons learned from this effort are explicitly stated in four categories: (1) cultural affairs (2) personnel and training (3) organisation and management and (4) leadership. Each 'lesson' is stated as a principle or guideline. Conclusions emphasise the importance of leadership, commitment, local control, long-range planning and the presence of a communications satellite. 相似文献

What are students expected to learn in physics courses? Eight expert physics teachers and researchers, two from the University of Western Ontario in Canada, Cambridge University in the United Kingdom, Stanford University in the United States of America, and Monash University in Australia, described their perceptions of learning in their courses. Students from the courses were then interviewed for their perceptions of learning in physics courses. In their courses, professors focused on the development of intellectual skills, assuming that students had a specific physics vocabulary. Students, however, were aware of their own limitations and suggested that professors should take nothing for granted. Students considered that to be a good teacher, a professor should know the perspective of the students and should start at the students' level. The results suggested that the intellectual challenge of learning physics merits early explanation. 相似文献
