To assess the impact of a holistic career and life planning course on college students, the authors asked 209 students in treatment and control groups to complete measures of career development. Results indicate that the course significantly increases vocational identity and career decision‐making self‐efficacy and decreases career indecision. 相似文献

In this study, the reading comprehension of deaf children and adolescents in the Netherlands is examined along with their
word identification. The reading comprehension of 464 deaf students and the word identification of 504 deaf students between
6 and 20 years of age was examined. The results show the reading comprehension scores of deaf children to be far below the
scores of hearing children. On average, the deaf subjects scored at a level equivalent to a hearing child in the first grade.
The word identification scores of the deaf children, however, were almost equivalent to the scores of hearing children. Although
reading comprehension and word identification appear to be related, this relation does not completely explain the comprehension
difficulties encountered by deaf children. Additional factors are required to explain deaf children’s difficulties with reading
comprehension. 相似文献

We present a curriculum that prepares students for supporting large Enterprise Information Systems (EIS). EIS is best explained
through the evolution of Enterprise Resource Planning (ERP). These systems evolved over the last years driven by (1) changing
business requirements and (2) new development capabilities provided by technologies evolution and software vendors’ innovation.
These developments led to a new discipline—Enterprise Information Systems, which deals with issues whose focus is on creating
and sustaining business benefits through the utilization of corporate IT infrastructure assets. Currently, EIS knowledge is
essentially acquired on the job after substantial time of experience building and longer career ladder scale. This paper presents
an experience of a curriculum implementation that prepares students for the pervasive EIS landscape in meeting today’s corporate
needs. Our IT-based educational approach is evaluated as an alternative to prevailing Business-based approaches to EIS instruction.
In this IT-rooted approach, the curriculum is divided into four sections: a Core IT block of courses followed by two progressive-levels
of advanced EIS-related specialized subjects, and an industry-oriented field-training experience. Initially, a Core IT background
provides a foundation for IT innovation in developing EIS components at sophomore-level. A junior-level of specialized instruction
introduces integrated modules which form EIS platforms. Finally, supporting technologies of EIS-related processes and workflows
are presented at senior-level of specialized EIS instruction. An assessment case study of the proposed Enterprise System programs
is carried out through which we discuss the results of the curriculum performance. 相似文献

The goal was to test a new dual identity perspective on gender identity by asking children (n = 467) in three grades (Mage = 5.7, 7.6, 9.5) to consider the relation of the self to both boys and girls. This change shifted the conceptualization of gender identity from one to two dimensions, provided insights into the meaning and measurement of gender identity, and allowed for revisiting ideas about the roles of gender identity in adjustment. Using a graphical measure to allow assessment of identity in young children and cluster analyses to determine types of identity, it was found that individual and developmental differences in how similar children feel to both genders, and these variations matter for many important personal and social outcomes. 相似文献

Meta-analysis was used to review the results of 25 studies that compared the classroom behavior of children and adolescents with learning disabilities (LD) to children without learning disabilities. The data were analyzed from several different methodological perspectives. Results showed that both methodologically strong and weak studies demonstrated significant behavioral deficits of children with learning disabilities compared to their nondisabled peers in each of five overall areas: on-task behavior, off-task behavior, conduct disorders, distractibility, and shy/withdrawn behavior. Both observational and teacher rating data demonstrated these differences. Effect sizes for both groups of studies seemed to cluster around 1 standard deviation, suggesting noticeable and educationally significant impairment in the behavior of children with disabilities. Analysis of grade-level effect sizes suggests some explanation for the large number of referrals often witnessed during the elementary school years. Educational implications of these behavioral differences in terms of implications for mainstreaming are discussed. 相似文献

The legal system is an important part of a society's response to child abuse and child neglect. Courts need to be guided in their deliberations by experts from many different professions. Consultation and in-court expert testimony is necessary from medicine, psychology, psychiatry, social work and other professions both to prove child abuse and neglect and establish the power of the court to act on behalf of a child but also to guide the court in the intervention strategy most suited to the needs of the child and his family. Non-lawyers often feel uncomfortable in the legal setting. The adversary process is foreign to their training and professional experience. Collaboration with a lawyer greatly improves their effectiveness in court. Lawyers, on the other hand, need to make maximum use of medical and social-psychological experts in the court process in the interests of their clients; but to do so lawyers need a basic understanding of the other professions. With an emphasis on a process of mutual education, the paper presents a framework for collaboration between lawyers and expert witnesses in child abuse and neglect cases. “Expert witness” is defined; informal consultation is encouraged; suggestions for selecting a collaborator are made; initial contracts between lawyer and expert, case conferencing and preparation for trial are discussed; specific advice on direct and cross examination is provided. 相似文献

This is a brief historical review of the key content and influence of the three predecessor publications to Learning, Media and Technology, the NECCTA Bulletin (1968–1975), the Journal of Educational Television (1975–1995), and the Journal of Educational Media (1996–2004). Study of these publications affords an overview of 40 years of using technology in the service of education. 相似文献
