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

A proof is a connected sequence of assertions that includes a set of accepted statements, forms of reasoning and modes of representing arguments. Assuming reasoning to be central to proving and aiming to develop knowledge about how teacher actions may promote students’ mathematical reasoning, we conduct design research where whole-class mathematical discussions triggered by exploratory tasks play a key role. We take mathematical reasoning as making justified inferences and we consider generalizing and justifying central reasoning processes. Regarding teacher actions, we consider inviting, informing/suggesting, supporting/guiding and challenging actions can be identified in whole-class discussions. This paper presents design principles for an intervention geared to tackle such reasoning processes and focuses on a whole-class discussion on a grade 7 lesson about linear equations and functions. Data analysis concerns teacher actions in relation to design principles and to the sought mathematical reasoning processes. The conclusions highlight teacher actions that lead students to generalize and justify. Generalizations may arise from a central challenging action or from several guiding actions. Regarding justifications, a main challenging action seems to be essential, while follow-up guiding actions may promote a further development of this reasoning process. Thus, this paper provides a set of design principles and a characterization of teacher actions which enhance students’ mathematical reasoning processes such as generalization and justification. 相似文献

SCHOOL RACIAL CLIMATE AND THE ACADEMIC ACHIEVEMENT OF AFRICAN AMERICAN HIGH SCHOOL STUDENTS: THE MEDIATING ROLE OF SCHOOL ENGAGEMENT 下载免费PDF全文

This investigation utilized an integrative model of development for ethnic minority children and a process model of engagement to explore whether three dimensions of school engagement (behavioral, emotional, and cognitive) mediated relationships between school racial climate, academic performance, and educational aspirations. A total of 139 African American students were recruited from a high school in the southeastern United States. Findings revealed an indirect association between perceptions of racial fairness and academic achievement indicators through behavioral and cognitive engagement. Behavioral and cognitive engagement also mediated relationships between youths’ perceived peer discrimination and academic achievement indicators. No significant indirect associations between teacher discrimination and academic achievement through school engagement dimensions were found. Study limitations, future directions, and implications are discussed. 相似文献

In this article we discuss an action research experience that took place from 2002 to 2015. We analyze the inception and progress of several project-based learning-centered academic courses that were aimed at developing the project management skills of graduate and undergraduate students. The experience involved approximately 1800 students from two universities and 40 community partners. The students developed real-life projects on behalf of institutions and non-governmental organizations located in the area that help people in need; we refer to these agencies as ‘community partners.’ We analyze the development of the course from a systemic perspective, making use of causal loop diagrams in order to understand the main driving dynamics. We discuss the results achieved by these projects and the benefits brought to the community partners. We also present testimony from the community partners themselves. We conclude by presenting the lessons we learned over the years we have been running this course. 相似文献
