Learning that takes place outside the formal classroom, called informal learning, has been a difficult parameter to assess due to the heterogeneous nature of the subjects and everyday learning situations. To date, no instrument has been developed to effectively examine the wide variety of informal experiences a child may encounter. Central to this study was the development and field testing of such an instrument, the Informal Learning Opportunities Assay (ILOA). The ILOA was administered to a total of 2128 middle and high school students and was found to be ethnically neutral, easily scored, and flexible in design to accommodate practitioners and researchers. The instrument was found to provide a reliable assessment of informal learning opportunities. 相似文献

Ann Lewis 《British Journal of Special Education》2004,31(1):3-9
The Gulliford Lecture 2003 was given by Professor Ann Lewis of the School of Education at the University of Birmingham. Professor Lewis's lecture, on which this article is based, focused on the process of listening to the views of children and, in particular, children with learning difficulties. Following the near-universal ratification of the United Nations (UN) Convention on the Rights of the Child, a plethora of recent initiatives, both in the UK and internationally, has encouraged professionals to access children's views about provision (educational, health-related, social and legal). A range of materials has been developed to support this process, often by, or in liaison with, children's charities. At the same time, research provides valuable insights into effective practice in exploring the views of children with learning difficulties. In this article, Ann Lewis reviews ten strategies for gathering the views of children and raises four challenges for the further development of policy and practice. She closes her argument with a call for greater rigour and critical evaluation in this crucial and demanding area. 相似文献

The effect on families and the changes that occur in relation to a child with disability or independently are considered through the life span. The recent advances in prenatal screening, special care baby units and genetic counselling may increase fear of disability and have not decreased the incidence. As the rest of the family grow older, the disabled child goes through school years, faces adult life, often with disappointments, and remains having special needs and specific vulnerability until old age. 相似文献

Findings on whether young infants look longer at incorrect addition and subtraction have been inconsistent or, as in our study, negative. We hypothesize that imprecise ordinal calculating with very small numbers of objects develops in late infancy and precise calculating in early childhood. 相似文献

This study employed a four-fold typology of opinion groups depictingthe relationships between minoritymajority status andaccurateinaccurate perception of the climate of opinionabout the 1990 prediction of a destructive earthquake for themid-United States New Madrid Seismic Zone. Data were collectedfrom 629 residents of the area where the earthquake was predictedto occur. Two frameworks were employed to define the climateof opinion to take into account two key variables that influencepublic response to earthquake predictions: the predication'sbelievability and its importance. Accurate perceptions of theclimate of opinion were differntiated from inaccurate perceptionsbased on more frequent media use and the confidence respondentsfelt about protecting themselves from potential earthquake damages.Inaccurate perceptions of the climate of opinion are differentiatednot by more extensive media use and discussions, but by thecrediability placed on the information from the news media anddiscussions, as well as the perceived influence of these informationsources. 相似文献

This paper examines how teachers responded when some organizational constraints on their work were loosened and why they responded as they did. It first reviews the sociological literature on teacher work to identify the main determinants studied. It then presents results of an ethnographic study of teachers in an urban school. The literature tends to portray teacher work as overly determined and may remove more responsibility from teachers for determining their own work than is warranted. 相似文献
