Japanese student activism in the 1970s

Student movements in Japan have, during the 1970s, tended to move from cooperation between various radical sects to bloody conflict among them, from participation by students generally to involvement by only a limited core of committed activists and from a struggle against the universityand society to one against society alone. The end of the war in Vietnam, the economic crisis, and other societal factors have contributed to these changes. The future of the student movement in Japan cannot be accurately predicted but it is unlikely that a powerful and politically effective movement, such as that of the 1960s, will re-emerge in the near future.     

A Case Study of Elementary Science Teaching as Mediated Action: Transformations of Context,Meaning, and Action

The research described in this article is a case study of a fifth grade teacher's (Melissa) efforts to construct a teaching and learning environment within her science teaching. Qualitative research methods were used to examine and analyze Melissa's science teaching practice. Drawing from socio-cultural theories, I argue that her teaching and learning environment was constructed as a form of mediated action through which she articulated and transformed the context, meaning, and action of her science teaching. In particular, she forged links between a number of factors, such as historically recognizable forms of pedagogy, perceptions of her students' socio-economic positions, knowledge of appropriate science teaching, and her experiences in a preservice teacher education program. Through her pedagogical work, the teaching and learning environment was articulated into a complex network of meanings, physical spaces, and concrete actions in which each element transformed the other. I suggest that mediated action is a form of transformation that constitutes context, meaning, and action into a dynamic and constantly-shifting teaching and learning environment.

A Practical Introduction to Authoring for Computer-Assisted Instruction. Part 7: Graphic support

Images provide a useful method of presenting information to an audience. In a learning situation the use of pictorial forms can offer a high-bandwidth mechanism for the transfer of information between an instructor and a student. This paper discusses some ways of providing graphic support in a computer-based learning environment and describes some approaches to the provision of authoring facilities that utilize this technique.     

Becoming a physician: The influence of the undergraduate experience

This study employed a national sample of college students who initially aspired to be, or later became, physicians to determine the influence of precollege characteristics, college origins, and the academic and social experience of college on the likelihood of becoming a physician. Estimates of a 14-variable causal model indicated that the major direct effects on attainment were attributable to college characteristics and the academic experience of college. Net of other causes, the selectivity/prestige of the undergraduate institution attended, collegiate academic achievement, and majoring in the physical or life sciences each had significant direct effects on becoming a physician. The direct positive influence of college quality, however, was partially counterbalanced by its negative indirect effect. Moreover, the greatest advantage in attending an elite institution accrued to those students with relatively high levels of academic performance. As academic performance declined, so did the positive effect of college quality. The effects of precollege characteristics on becoming a physician were largely indirect, mediated by the student's college experience. Net of other factors, women were no less likely than men to become physicians, but being female had a significant negative indirect effect. Conversely, secondary school achievement did not directly influence attainment but did have a large positive indirect influence.An earlier version of this paper was presented at the annual meeting of the Association for the Study of Higher Education, San Diego, February, 1987.     

Vocational Interests and Career Efficacy Expectations in Relation to Occupational Sex-Typing Beliefs for Eighth Grade Students

Following the recommendations of Lent, Brown and Hackett's Social Cognitive Career Theory (2000), we measured eighth grade boys' and girls' perception of the proportion of men and women employed in occupations and their level of interest and self-efficacy for those occupations. Results indicated that eighth grade boys and girls expressed stronger career interest in and higher self-efficacy for those occupations that they rated as employing more of their own gender. The study highlights how career practitioners can work with adolescents to widen their perceived range of occupational choices.     

Science related attitudes amongst Victorian catholic primary school teachers

Conclusion This study is preliminary in nature, and the instrument will require some modification to reduce its length and to further increase the reliability of the attitude scale. None-the-less, in addition to replicating some important aspects of previous studies, and introducing a measurement of primary school teachers' science related attitudes, it does provide valuable data prior to the introduction of the new course guides. When used in conjunction with the findings of a similar survey which is to be conducted in 1983, these data will help to assess the impact of the introductory phase of the course in Victorian Schools.     

A fresh approach to child protection practice and legislation in Australia

This paper outlines some of the findings and approaches of the Victorian Review. It assesses a stylized "orthodox model" of child welfare law and practice, a model which remains in many Australian jurisdictions and which has its popularity in Britain, Canada, and the United States. It concludes that serious consideration should be given to rebuilding and strengthening these arrangements. This entails emphasis on utilizing laws to serve an educative function and facilitating access by children and families to preventive and support services. It argues that a broad concept of neglect should be adopted and that the "welfare orientation" of the Children's Court requires reconsideration, because the capacity of courts to resolve entrenched structural problems of society has been overrated. Welfare practice, and specifically a community approach to welfare, should shape the primary response to protection of children; judicial involvement should be a last resort.     

Transfer of facilitation in the rat

In two experiments, rats solved two concurrent discrimination problems in which one stimulus (i.e., a facilitator) signaled the reinforcement of another stimulus (i.e., a target). Then a transfer test assessed the capacity of facilitators trained in one problem to promote responding to targets trained in the other. Experiment 1 found that a facilitator promoted as much responding to such a transfer target as to the target with which it was originally trained. Transfer was not obtained with a pseudofacilitator that was uninformative, in training, about the reinforcement of its target. Experiment 2 manipulated the stimulus modality of the targets and facilitators. Its results indicated that transfer performance was not due to generalization between training and transfer targets or facilitators. These results parallel those from comparable autoshaping paradigms with pigeons, and they agree with the view that facilitators promote responding by lowering the threshold for activation of the US representation.
