This study was conducted to determine if a planning and writing strategy would improve the essay writing of students with learning disabilities. Four participants were taught a strategy designed to facilitate the setting of product and process goals, generation and organization of notes, continued planning during writing, and evaluation of goal attainment. Training effects were investigated using a multiple probe design across subjects. Strategy instruction had a positive effect on students' essay writing performance and knowledge of the writing process, and effects were maintained over time. 相似文献

Kindergarten, third-grade, and sixth-grade children were told 2 stories about a group of children who made artwork that was subsequently sold at a craft fair. The characters in one story were described as friends, while the characters in the other story were described as strangers (relationship condition). 1 character in each story was presented as the oldest in the group, 1 as the most productive, and 1 as the poorest. Children were asked to allocate 9 dollars to the 3 characters under each relationship condition, provide rationales for those allocations, and rate the fairness of 4 different patterns of allocation. Older children allocated more money to needy friends than to needy strangers and more to productive strangers than to productive friends. Kindergartners' allocations and fairness ratings did not vary with relationship. Rationales for allocation judgements suggested that equality was the most salient principle for decisions at all ages, but the older children provided rationales based on benevolence more often than younger children when characters were presented as friends. 相似文献

This article examines the traditional assumption that higher education evaluation systems follow a similar global format. Comparative study examines institutional evaluation and assessment processes in two nation‐states that are geographically and economically remote but which, historically, share a common civic perspective. The main research question of the study is: What are the similarities and differences in the social functions of evaluation and assessment between these two countries, the models of evaluation of which originate from the same “homogeneous model of institutional evaluation”? The study demonstrates that Finnish and Argentine models of evaluation are nationally and contextually bound by general ideas rather than being applications of a global model. 相似文献

In 2001, for the first time in the history of the International Association for Counselling, International Conference was held in a developing Asian country–India, with the theme Families in Transition–Counselling in Transition–Meeting the Challenges Ahead. This special issue contains some of the presentations made by Indian participants during this conference which best reflect the challenges and diversities of counseling efforts with families in India. The first article was specially written for this issue in order to give an international relationship of this journal an in depth contextual understanding of Indian families in transition and the challenges they pose to the contemporary Indian counselor. Two articles are reflected to counseling families affected by socio-politial and economic changes. Five authors have written on counseling related to physical and mental disability/addiction and last two articles are reflected to authors experiences as family counselors. 相似文献

Kinetic knowledge is of great importance in achieving good control of the pyrolysis and gasification process and optimising
system design. An overall kinetic pyrolysis scheme is therefore addressed here. The kinetic modelling incorporates the following
basic steps: the degradation of the virgin biomass materials into primary products (tar, gas and semi-char), the decomposition
of primary tar into secondary products and the continuous interaction between primary gas and char. The last step is disregarded
completely by models in the literature. Analysis and comparison of predicted results from different kinetic schemes and experimental
data on our fixed bed pyrolyser yielded very positive evidence to support our kinetic scheme.
