Anne Harris Cohn 《Child abuse & neglect》1979,3(2):491-496
Not all child abuse is preventable. Society faces an ongoing need to support programs that treat the members of families in which abuse occurs. There is little systeamatically generated knowledge on the most efficient and effective ways to assist parents and children faced with abuse. The purpose of our 40-month study of eleven child abuse and neglect demonstration service programs in the United States was to expand the knowledge base in this area by determining, through evaluative research, the essential elements of successful treatment programs. This paper highlights our findings that pertain to more effective delivery of services to abusive and neglectful parents. 相似文献

In the light of challenges arising from contemporary issues such as inclusivity, sustainability and justice, the connections between art, design and caring appears to be pertinent. What role can artists and designers play in the ecology of care? How can we lead art and design students to connect and lend their creative skills to care needs? Drawing on the ethics of care and a relational view on health this article highlights the various teaching approaches and initiatives introduced at Nanyang Technological University, Singapore, to support and guide students to realise various art and design for health and wellbeing projects that provide opportunities for students to part take in ecology of care using their creative skills. Although creative explorations at the intersection of art, design and caring is still at an early stage, outcomes from this ongoing effort have been encouraging in response to the shifting social needs to create a more inclusive and flourishing society in Singapore. 相似文献

A synthesis of the commentaries to our leadoff paper is presented, along with our replies to some of the specific comments offered. When the original analysis and the commentaries are combined, an exceptionally thorough summary of issues that should be considered by intervention researchers emerges. We hope this set of issues will be useful to the educational research community.A draft of this synthesis was circulated among the commentators in this special issue, with a request to determine whether their views were represented fairly. There were few reservations expressed, and in every case when a concern was expressed, we concluded on review that slight adjustment was required to present the commentator's perspective more clearly and/or fairly, and we attempted to do so. 相似文献

In the course of a decade of research on learning in technology‐centered classrooms, my research group has gained considerable understanding of why and how students learn science by designing technology. In this article I briefly review two dimensions in which science and technology share fundamental similarities: (a) the production and transformation of representations and (b∥ the action‐oriented language describing the two domains. Because it is fundamentally problematic to derive what ought to happen in science classrooms from other dimensions, I provide three episodes to illustrate what and how students know and learn science during technological design activities. Episodes and analyses embody the two dimensions previously outlined. Because these episodes are representative of the database established during an extensive research program, I suggest there is sufficient ground for using and investigating science‐through‐technology curricula. © 2001 John Wiley & Sons, Inc.

Conclusion The Strategic Impact Model is distinctive in its portrayal of the integration of instructional and non-instructional interventions
and its suggestion that all performance interventions undergo an analysis-design-development-production cycle, just as instruction
does. It also differs from other similar models in its use of evaluative activities at each stage to assure alignment with
strategic needs as well as quality control, and its suggestions for improving the chances of successful implementation by
carrying out change management activities at each phase of the development process.
He has special interests in distance education, historical and philosophical foundations of instructional technology and instructional
development processes.
He has special interests in planning and evaluating performance improvement initiatives, including training.

The learning cycle is a method of teaching—it is also a curriculum organization principle and is derived directly from the mental functioning model invented by Piaget. Although Jean Piaget contributed to the formation of the learning cycle (Piaget, 1973), its present structure has to be attributed to Dr. Robert Karplus and the persons who developed the materials of the Science Curriculum Improvement Study (SCIS). It was through the SCIS activities that many of us learned how to develop curricula and teach with the learning cycle. The learning cycle is built upon the premise that three distinct phases are necessary in developing understanding of a concept, that those phases have a definite sequence, and each phase has a definite structure or form. The research done in testing the form variable has already been reported in this journal (Renner, Abraham, & Birnie, 1985). This report explores whether or not each learning-cycle phase is necessary in learning a concept. 相似文献

This study focuses on an industrial, commercial and community experience programme within a full time, one year postgraduate teacher training course. Acknowledging the heterogeneous experiences brought to this course by the students, an attempt was made to detect links between the students’ prior experience and their experience of the industrial, commercial and community programme. The students completed questionnaires before and after a placement and the findings are described. These findings contribute to an evaluation of the programme and suggest a number of important questions for those responsible for designing teacher education courses. 相似文献

Theories of adolescent connectedness suggest that adolescents strive to become connected by engaging with and valuing the
people, activities, and worlds in their social ecology. The purpose of this study was to examine the psychometric properties
of a measure designed to assess these worlds of connectedness among 320 junior high school students in Taiwan. The subscales
and composite scales evidenced satisfactory reliability and concurrent validity. A hypothesized three-factor, higher order
structural model of connectedness was cross-validated. Girls were generally more connected than boys. Both connectedness to
school and to friends explained more variance in connectedness to self than did family connectedness. There was mixed support
for separation-individuation processes. The measure appears promising in terms of future research on adolescent social development
in the Asia Pacific. 相似文献

Caption rate and text reduction are factors that appear to affect the comprehension of captions by people who are deaf or hard of hearing. These 2 factors are confounded in everyday captioning; rate (in words per minute) is slowed by text reduction. In this study, caption rate and text reduction were manipulated independently in 2 experiments to assess any differential effects and possible benefits for comprehension by deaf and hard-of-hearing adults. Volunteers for the study included adults with a range of reading levels, self-reported hearing status, and different communication and language preferences. Results indicate that caption rate (at 130, 180, 230 words per minute) and text reduction (at 84%, 92%, and 100% original text) have different effects for different adult users, depending on hearing status, age, and reading level. In particular, reading level emerges as a dominant factor: more proficient readers show better comprehension than poor readers and are better able to benefit from caption rate and, to some extent, text reduction modifications. 相似文献
