Disabilities Among Norwegian Students Found Eligible for Special Education     

Karl J. Skårbrevik 《International Journal of Disability, Development & Education》2001,48(3):253-268

The prevalence of different disabilities in a sample of 780 students found eligible for special education in Norway is presented in this article. Each student was judged in relation to 10 different disabilities, and the frequencies of the different disabilities were reported. Almost all students had more than one problem or disability. It is argued that statistics related to students with disabilities that ascribe each student only to one category of disability do not provide a correct picture of the prevalence of different disabilities. The most common disabilities reported in this study were psychosocial problems, intellectual disability, and communication disorders that were found in about 40 to 50% of the students. About one third of the students were reported to have attention deficit disorder or physical disabilities, 25% experienced social stress outside school, and 20% had medical problems. Hearing and visual impairments are reported for about 5% and 6% of the sample respectively.  相似文献

Fostering house mice onto rats and deer mice: Effects on response to species odors     

Karl L. Wuensch 《Learning & behavior》1992,20(3):253-258

Newborn wild house mice (Mus musculus) were fostered upon maternal conspecifics, prairie deer mice (Peromyscus maniculatus bairdi) or laboratory rats (Rattus norvegicus). Male subjects were weaned into individual cages, in which they remained until testing commenced. At 35 days of age, subjects were given a four-choice test in which they had the opportunity to investigate tunnels scented with clean wood chips or with chips soiled by an adult male conspecific, deer mouse or rat. Compared to theMus-nursed andPeromyscus-nursed mice,Rattus-nursed mice were more active during the test and less reluctant to investigate theRattus-scented tunnel. These results were replicated in a two-choice test (Mus- vs.Rattus-scented tunnels) that included a group of mice fostered onto conspecifics, but withRattus scents present in the maternity cage throughout the nursing period. Early exposure to the scent ofRattus had no significant effects on the responses ofMus-nursed mice to the scent ofRattus.  相似文献

Using Research to Improve the Cost Effectiveness of Early Intervention Programs     

Karl R. White 《Early education and development》1993,4(4):346-358

Since the implementation of Public Law 99457, the number of children served by early intervention programs has increased substantially. This article describes the d e s of advocacy and science in contributing to that expansion. A biosocial systems model of early development is used to explain how comparative experimental research can help to improve the cost effectiveness of early intervention programs. Examples of the benefits of such research are taken from the other articles reported in this issue of Early Education and Development.  相似文献   

Teacher–student interaction in contemporary science classrooms: is participation still a question of gender?†     

Nina Eliasson  Helene Sørensen  Karl Göran Karlsson 《International Journal of Science Education》2016,38(10):1655-1672

We show that boys still have a greater access to the space for interaction in science classrooms, which is unexpected since in Sweden today girls perform better in these subjects than boys. Results from video-recorded verbal communication, referred to here as interaction, show that the distribution of teacher–student interaction in the final year of lower secondary school follows the same patterns as in the 1980s. The interaction space for all kinds of talk continues to be distributed according to the two-thirds rule for communication in science classrooms as described by previous research. We also show that the overall interaction space in science classrooms has increased for both boys and girls when talk about science alone is considered. Another finding which follows old patterns is that male teachers still address boys more often than girls. This holds true both for general talk and for talk about science. If a more even distribution of teacher–student interaction is desirable, these results once again need to be considered. More research needs to be undertaken before the association between girls’ attitudes and interest in science in terms of future career choice and the opportunity to participate in teacher–student interaction is more clearly understood.  相似文献   

Risk factors for the perpetration of child sexual abuse: a review and meta-analysis   总被引：1，自引：0，他引：1  

Whitaker DJ  Le B  Karl Hanson R  Baker CK  McMahon PM  Ryan G  Klein A  Rice DD 《Child abuse & neglect》2008,32(5):529-548

OBJECTIVES: Since the late 1980s, there has been a strong theoretical focus on psychological and social influences of perpetration of child sexual abuse. This paper presents the results of a review and meta-analysis of studies examining risk factors for perpetration of child sexual abuse published since 1990. METHOD: Eighty-nine studies published between 1990 and April of 2003 were reviewed. Risk factors were classified into one of the following six broad categories: family factors, externalizing behaviors, internalizing behaviors, social deficits, sexual problems, and attitudes/beliefs. Sex offenders against children (SOC) were compared to three comparison groups identified within the 89 studies: sex offenders who perpetrated against adults (SOA), non-sex offenders, and non-offenders with no history of criminal or sexual behavior problems. RESULTS: Results for the six major categories showed that SOC were not different from SOA (all d between -.02 and .14) other than showing lower externalizing behaviors (d=-.25). Sex offenders against children were somewhat different from non-sex offenders, especially with regard to sexual problems and attitudes (d=.83 and .51). Sex offenders against children showed substantial differences from non-offenders with medium sized effects in all six major categories (d's range from .39 to .58). CONCLUSION: Child sex offenders are different from non-sex offenders and non-offenders but not from sex offenders against adults. PRACTICE IMPLICATIONS: This study suggests that the presence of general risk factors may lead to a variety of negative behavioral outcomes, including the perpetration of child sexual offending. Family factors were strongly related to the perpetration of child sex offending (vs. non-sexual offending or non-offending) and may be valuable intervention points for interrupting the development of child sex offending, as well as other negative behaviors. Other potential points for intervention may focus on the development of appropriate social and emotional skills that contribute to sexual offending.  相似文献   

Exploring the boundaries: A study of multiple classroom learning environments     

Dr Stephen M. Ritchie  Kenneth Tobin  Karl S. Hook 《Research in Science Education》1995,25(3):307-322

The study of learning environments has developed into a productive field of research in science education. Initially, the design and application of classroom perceptual measures of particular dimensions of science classrooms attracted much attention. More recently, such instruments have been used alongside of qualitative techniques to provide a richer understanding of sub-environments. We continue this trend in the present interpretive study by exploring the nature of multiple environments within a middle school classroom from the different perspectives of teacher, student and participant observer. In particular, we examine the activity settings of lectures and group work, as well as the issues of learning and assessment. We conclude by arguing that teachers need to adopt procedures that enable them to identify and plan for multiple environments.  相似文献   

Cognitive Teaching Methods for Special Education: Development of Approaches for Intervention and Assessment in Germany     

Gerhard W. Lauth  Karl H. Wiedl 《International Journal of Disability, Development & Education》1989,36(3):187-202

FOLLOWING a short introduction to historical aspects of the development of cognitive teaching methods, four current areas of research are described: cognitive behaviour modification with a focus on problem solving and metacognitive abilities, comprising the methods of cognitive modelling and self‐instruction; intelligence training based on the theoretical propositions of inductive thinking; attempts at applying Piagetian concepts as a conceptual framework for education and training; dynamic testing, focussing on modifiability of performance and thus bridging the gap between diagnostic assessment and education. Basic theoretical assumptions, methods and applications are separately discussed for each of these fields. Empirical data are presented for evaluation of their level of development Summarizing the results, it seems, that promising effects of training and fruitful application of diagnostic procedures can be obtained; however, implementation of the respective methods in special education settings does not show great progress. It is, thus, concluded that research on implementation is indispensable.  相似文献
