We investigate the nature of protests by students (age 18 and older) in Algeria, Jordan, Morocco, and Yemen by using subsamples of students from nationally representative and acclaimed public opinion data (the 2006–07 Arab Barometer). We find between 22.1% (Jordan) and 54.7% (Yemen) participated in either the signing of petitions, or marching in street protests, or both between the years 2003–07. To explain student protest participation, we draw from the political economy literature to test four grievance-based hypotheses that link protest to student perceptions on the performance of the economy, personal family socioeconomic status, political exclusion, and preference for democracy. Ordered probit regression analyses indicate that students protest for different reasons in the four countries. We find statistical evidence that student protests are associated with grievances about the economy (Algeria and Morocco) and lack of democracy (Algeria only). Joint hypothesis tests reveal that the four grievances jointly matter in Algeria, Morocco, and Yemen but not Jordan.  相似文献

This paper puts forward the proposition that in times of fiscal stringency adult educators have relied on two basic responses: either align programs to suit current political imperatives or bring pressure to bear to maintain the status quo. However, neither of these may be adequate to cope with what now appears to be a more fundamental change in our economy resulting in permanently high unemployment and the increasing importance of work in the informal economy. These two factors emphasise the difficulty of continuing to accept the current work‐leisure dichotomy that underlies much of our thinking and presage a dramatic change in the ways some people may have to gain their livelihood. Adult educators have had a significant role to play in individual and community economies but this is largely unrecognised due to the fact that adult education practitioners have tended to justify their work on quality‐of‐life or numbers grounds. Such justifications may no longer be adequate. If adult educators wish to maintain their programs in hard financial times they certainly have the capacity to do so but they will have to rethink their rationale, reject outmoded beliefs and patterns and justify their work through the outcomes of their programs and not just the outputs.  相似文献

This investigation examined changes in children's perceptions of the elderly following an intervention in the frequency of contact that school‐aged children had with old people. Elderly persons served as tutors in a reading tutorial program for a period of two months. Pre‐and postintervention measures of attitudes and reading skills were taken from the children; measures of morale were obtained among the elderly sample. Evaluations of the program were also provided by the elderly, the children, school principals, and teachers. An analysis of variance revealed a significant interaction effect of group by test, suggesting that even a relatively brief intervention can modify children's perceptions of the aged. Although there were no significant changes in the responses of the elderly subjects as measured by objective questionnaires, the majority of the tutors reported that they were happier and felt more involved in the community while working in the program.  相似文献

The perceptual and cognitive processing demands involved in comprehending complex animations can pose considerable challenges to learners. There is a tendency for learners to extract information that is highly perceptually salient but neglect less conspicuous information of crucial relevance to the building of a quality mental model. This study investigated the effectiveness of self-generated drawing for learning from an animation illustrating a scientific phenomenon, the so-called “Newton’s Cradle.” Participants were 199 students in grade seven, randomly assigned to three experimental conditions: self-generated drawing, traced/copied drawing, and no drawing. All participants were asked to produce an explanation of the animation for both immediate and delayed posttests. The results revealed the superiority of self-generated drawing in supporting animation comprehension at both testing times compared to the other two conditions, which did not differ from each other. In addition, comprehension of the animation was related to the quality of self-generated drawings. Specifically, the depiction of information characterized by low perceptual salience but high conceptual relevance to the phenomenon predicted comprehension and retention over time.  相似文献

The question of theory change is crucial in knowledge construction, particularly in the process of conceptual change. This study was designed to investigate two factors that, in addition to initial theory preference, may play a crucial role in the process of theory change, that is, students’ interpretation of anomalous data on two controversial topics (the dinosaur extinction and the construction of the Giza pyramids in Egypt) and their epistemological beliefs about the nature of knowledge. Canonical correlation analyses suggested for both topics an association, stronger for the dinosaur extinction topic, between (a) acceptance of anomalous data (rated both as valid and inconsistent with the held theory), initial theory preference, epistemological belief in Certain Knowledge and (b) theory change. Data obtained from structure coefficients in canonical correlation analyses indicate that acceptance of anomalous data significantly contributed the most to theory change whereas the epistemological belief contributed the least. Finally, educational implications are drawn.  相似文献
