This study was designed to assess the impact of taking a high quality picture book home from school daily on the at-home reading behaviors of young children and/or family members from middle and low SES backgrounds. Eighty children representing two study groups (treatment & no-treatment comparison) and two socioeconomic groups (Head Start & middle-class) composed the study sample. Treatment children selected picture books at school daily to take home over a 12-week period. Child and family picture book reading behaviors were assessed by weekly random telephone surveys. Findings indicate that taking a picture book home daily more than doubled the number of books read at home for both middle-class and Head Start treatment children over their no-treatment comparison counterparts and significantly increased the amount of time Head Start treatment children were involved in reading each day. The practicality of making high quality picture books available for preschool children to take home and the implications of increased at-home reading behaviors are discussed.  相似文献

This paper outlines the work of the Basildon Marital/Family Violence Project set up as a result of two studies undertaken by the National Society for the Prevention of Cruelty to Children (N.S.P.C.C.) School of Social Work, which looked at the effect of marital violence upon the children involved. These effects were classified under the following headings: (1) the children were scapegoated; (2) used as pawns in the marital battles; (3) turned agression against themselves; (4) had relationship problems at school; (5) were physically assaulted by the parents in 25% of the cases. The project, which is now in its 4th year, has offered social work services, consultation, training courses and research. Work with the families, and particularly with the children, has further emphasised the severe emotional damage that marital violence can have upon the children. The paper optimistically reports that after intensive work using a five-point treatment programme, and direct work with the children, there has been considerable diminution of violence in many of the cases and in some cases no repetition of such violence at all. The worker's approach, it is suggested, should be characterised by optimism combined with indestructible calm, genuine empathy combined with 24-hour access, persistence in the face of lack of progress, enhancement of parents' low self-esteem, regular contact and an ability to contain destructiveness.  相似文献

Nonverbal learning disabilities and remedial interventions   总被引:1,自引:0,他引:1  
Adolescents with nonverbal learning disabilities who enroll in private, special secondary schools consistently present a pattern of behaviors which prevents achievement of their potentials in academic areas and impedes their abilities to interact effectively with others. With weaknesses in the fine graphomotor skills for writing and poor organization at all levels, they produce limited written output and often fail to complete academic assignments. Their response to pressure to produce is to become less productive. These students perceive social situations inaccurately; they are not successful in their interactions, especially with peers. They have learned to resolve difficult situations by employing their relatively strong verbal skills to enlist parents and other adults in intervening for them. They have not developed the skills to intervene for themselves. Effective remedial interventions include training the students in skills for planning and organizing, for studying, for written expression, and in social cognition and interpersonal communication. Students gain positive feelings of personal effectiveness through a process—at first verbally mediated, ultimately verbally self-directed—in which they are encouraged to plan, risk, and act on their own behalfs to resolve matters of personal concern.  相似文献

This article describes a case study of six girls' experiences with the Phoenix Quest computer game. In addition to the case study, a supplementary large-scale study of the reactions of both boys and girls to the same computer game was conducted for comparative analysis. Phoenix Quest (PQ) was designed not only to encourage children to explore language and mathematics, but also to offer game features that would especially appeal to girls. Participants in the case study were given opportunities to become acquainted with PQ for several months before being observed and interviewed. Four issues that emerged as being important to the participants were (a) presentation of the story in a non-linear format, (b) appreciation for the problem-solving elements of PQ, (c) identification with the main character (female), and (d) lack of awareness of the mathematics embedded within the game. The findings provided evidence that PQ appealed to girls because the protagonist was of their age and gender, and because the puzzles and searches were engaging throughout the game. Some aspects of the game, however, were less successful; for instance, the non-linear story format was disconcerting to all but one of the participants, and only one student identified the mathematics in the game structure. The large-scale study involved 41 boys and 57 girls, aged 8-12, from four junior school classes (Grades 4, 5 and 6). The aggregate data collected showed that more girls than boys used the postcard-writing feature of PQ and appreciated following the adventures of a female protagonist. More boys than girls were reported to offer advice to other students, discuss the game during their free time, and observe others playing the game. Some boys even formed groups to exchange information and game-playing strategies. Also, more boys than girls recognised the mathematics embedded within the game. Although these studies did not focus on teacher-student interaction, the finding that more than 25% of participating students were not able to identify the mathematics embedded in PQ, supports supplementary instruction on the part of a teacher as a requirement for making the mathematics more salient. Further research to address this issue is strongly recommended. Both the case study and the large-scale study revealed that among computer games, PQ's uncommon approach of celebrating and challenging a female protagonist is important to girls. This does not suggest that the presentation of a female protagonist will discourage boys from playing and enjoying the game. On the contrary, our findings showed that boys were also engaged by PQ, a game that encourages cooperative play and group problem-solving. In the realm of computer games, gender identification plays a key role, in first capturing the attention of girls, and then sustaining their interest, enjoyment and participation.  相似文献

The rodents, especially voles, evolved very rapidly during the Quaternary era. Their remains, particularly the teeth, were fossilised by the thousand in prehistoric deposits. The sites can be dated from the degree of evolution attained by the teeth. Since rodents are closely adapted to their biotopes and live under well defined climatic conditions, they are extremely valuable for reconstructing the landscapes and climates of prehistory. In many cases, a single rodent tooth can be used to assess the age of a human skull or a prehistoric settlement, and throw light on the environment and climate of the time.  相似文献

The R. R. Bowker Company has been compiling and publishing statistics on the book industry for more than a century. The history of this effort is reported, with details on how the collection, classification, and publication of data have evolved. Bowker provides statistics on book title output, booksellers (retail and wholesale), and libraries. Jean Peters is the librarian at the Frederic G. Melcher Library, Cahners Publishing Company, formerly the library of the R. R. Bowker Company.  相似文献
