While instructional objectives have provided a cornerstone for the practice and science of instruction, they have also locked us into a lexically based conceptual system. In order to realize the interactive potential of computer-based instructional systems, we need a new way of representing performance. This paper presents the concept of a work model which is a unit of practice which allows replication of both information and interaction. In addition, the work model idea also addresses some of the fundamental problems with objectives such as their inability to capture the richness of terminal behavior or how to relate objectives to content. 相似文献

A mother's question of whether to believe her child's disclosure of intrafamily child sexual abuse is complex, with many factors influencing her conclusion. Variables related to the abuse and to the family's functioning are examined to determine if particular circumstances are too threatening to mothers, resulting in their disbelief. The findings indicate that the age of the victim, nature of the abuse, presence of the mother in the home during the abuse, relationship of the victim to the offender, prior physical abuse of the child, and alcohol abuse by the offender all contribute to mother's conclusion regarding the reported abuse. The majority of mothers do believe their child, with difficult situations and other family stressors occasionally detracting from a mother's willingness to accept the report. 相似文献

This paper reports on the professional development of a small group of newly qualified teachers (NQTs) who began their careers in four rural schools in Eritrea. These teachers were monitored over a period of four years from 2001 to 2004. Their development as primary practitioners was recorded by videoing and observing their classes and by interviews and informal discussions held over the period. The ways in which they developed and the factors involved in this development are analysed and discussed.It is hoped that this research offers an insight into the challenges faced by newly qualified teachers in small rural communities, often very much dependant on their own resources and those of the local community. This indicates ways in which the current programme and on-going in-service provision may be targeted in future. An important point is made that in spite of the unusual circumstances of education in Eritrea this research provides insights that are relevant to other sociocultural contexts. 相似文献

College students completed a questionnaire that assessed their attitudes toward the level of male responsibility in abortion decisions. Overall, both men and women thought that men should have some degree of involvement in the abortion decision. However, as expected by the first hypothesis, men indicated a desire for more responsibility in the abortion decision than women thought the men should have. A second hypothesis predicted women would feel more strongly than men that abortion was strictly a woman's issue. Contrary to the hypothesis, women tended to disagree that abortion was strictly a women's issue. Implications of the findings are discussed. 相似文献
