Teacher motivation to implement an educational innovation: factors differentiating users and non-users of cooperative learning     

Philip C. Abrami  Catherine Poulsen  Bette Chambers 《教育心理学》2004,24(2):201-216

This study applied expectancy theory to integrate the numerous and disparate explanations that researchers and educators have proposed to account for teacher resistance to implementing cooperative learning as an educational innovation. The cooperative learning implementation questionnaire (CLIQ) contained 48 items grouped under three broad motivational categories: perceived value of the innovation, expectancy of success, and perceived cost. These items accounted for 42.3% of the total variance in self-reported use of cooperative learning among 933 teachers. Expectancy of success issues were most important in differentiating users and non-users, suggesting that increased emphasis on professional development should be used to enhance teachers' beliefs that they can succeed in implementing an innovation in their own context. This may require both follow-up support and adaptation of the innovation.  相似文献   

What Is Right About Special Education     

Cynthia R. Chambers  Michael L. Wehmeyer  Yumiko Saito  Kerry M. Lida  Youngsun Lee  Vandana Singh 《Exceptionality》2013,21(1):3-15

Abstract

Promoting self-determination has become an important aspect of the educational programs of students with disabilities. There is now a sufficient literature base to support some syntheses that enable researchers to judge their progress in this area to date and to provide direction for future research and practice. For this study, we conducted a literature review of studies that measured or examined global self-determination.  相似文献   

Emission of electrons from cold metal surfaces     

Carl C. Chambers 《Journal of The Franklin Institute》1934,218(4):463-484

The results of Del Rosario on cold emission are shown to result from the fact that, through the attainment of specially good vacuum conditions and freedom from contamination, the cold electron current from the wire was suppressed up to field strengths greater than those at which measurable current was obtained in the work of previous observers. It was in fact suppressed beyond the point at which discharge started from points on the welding of the support. The results of Del Rosario are thus probably characteristic of conditions other than those pertaining to the wire, a conclusion which accounts for his current voltage curves. The formula of Fowler and Nordheim is found to apply in the measurable regions in form directly and in magnitude only if irregularities of the surface are such as to raise the field at the surface to a sufficiently high value. Breakdowns after intense heat treatment are studied and found to be caused by immeasurably small currents of electrons knocking ions from the anode. The erratic original curves obtained by previous investigators are found to be caused by successive breakdowns similar to those found after intense heating.  相似文献   

Vaginal lacerations from consensual intercourse in adolescents     

Frioux SM  Blinman T  Christian CW 《Child abuse & neglect》2011,35(1):69-73

Objective

(1) To describe lacerations of the vaginal fornices, an injury known to be associated with consensual sexual intercourse, including known complications and treatment course, (2) to contrast these injuries with injuries sustained during sexual assault, and (3) to discuss the assessment of adolescent patients for sexual injuries.

Methods

We present a case series of 4 female adolescent patients seen at a children's hospital over a period of 6 months. Each patient developed significant vaginal bleeding after sexual intercourse, and 3 of the patients presented to the emergency department with vital signs consistent with compensated shock.

Results

Each patient was evaluated by pediatric surgery, and found to have a laceration of the vagina. Three of the patients described consensual intercourse prior to the onset of bleeding, and had lacerations of the vaginal fornices; these patients were determined to have injuries resulting from consensual sexual intercourse. The fourth patient reported sexual assault as the cause of her injuries, and was treated for longitudinal lacerations of the vaginal wall.

Conclusions

Lacerations of the upper vagina are not frequently reported in forced vaginal intercourse, but are occasionally reported as injuries sustained during consensual coitus. In the absence of reported sexual assault, a severe vaginal fornix laceration is consistent with the diagnosis of coital injury from consensual intercourse. Diagnosis and treatment of this injury can be delayed due to the sensitive nature of these injuries. Bleeding can be profuse, leading to hemorrhagic shock, and these injuries may require transfusion of blood products and surgical repair in some cases. Complications may include hemoperitoneum, pneumoperitoneum, or retroperitoneal hematoma, even in the absence of complete vaginal perforation.

Practice implications

Knowledge of the consensual sexual injuries that may occur in adolescent patients can guide diagnosis, treatment, and counseling for the patient and her family, preventing long-term medical complications and legal consequences.  相似文献   

Theo Jansen project in engineering design course and a design example     

Yucheng Liu  Aaron Artigue  Jeremy Sommers  Terence Chambers 《European Journal of Engineering Education》2011,36(2):187-198

Objectives of a project-oriented mechanical engineering course, Engineering Design, were achieved through a design project, where students designed, built and demonstrated an extreme version of a basic Theo Jansen device. Through this project, junior students in the University of Louisiana fully developed the capability of applying mathematic and kinematic knowledge in the analysis and design of mechanisms. Students also developed oral and written communication skills, which would be used in design environments, through the presentation of results in both oral and written forms. An assessment of the design project indicated that effective teaching and learning spread through the semester, with the junior students acting as project managers and experiencing design practices. An example of a student-designed Theo Jansen device is presented in this paper to show the study results achieved by the students.  相似文献   

Challenging the premises of international policy reviews: an introduction to the review symposium     

Noah Weeth Feinstein  Jeppe Læssøe  Nicole Blum  Dianne Chambers 《Environmental Education Research》2013,19(2):198-205

In 2009, a think tank called the International Alliance of Leading Education Institutes (IALEI) announced the results of a study entitled Climate Change and Sustainable Development: The Response from Education. Intended for a policy audience, the study offered a glimpse into the status of Education for Sustainable Development (ESD) and an early look at the emergence of Climate Change Education (CCE), in 10 different nations. As with most international reports, the IALEI report provoked many questions, some of which are more broadly relevant to scholarship and practice. This paper introduces a review symposium that addresses three such questions: (1) How coherent is the concept of ESD across national contexts and what conceptual tensions continue to surround ESD and CCE? (2) Can nation-level analyses tell us anything useful about countries where education is not centrally governed? and (3) In light of the evolving relationship between educational research and policy, how should researchers engage with ongoing policy debates?  相似文献   

Interactive Video: a genuine or imagined potential     

J Chambers 《British journal of educational technology : journal of the Council for Educational Technology》1987,18(1):21-24

A combination of high production and hardware costs, limited programme demands and cheap and easy videotape alternatives are likely to restrict severely the progress of interactive videodisc in schools and possibly elsewhere. These reservations are discussed.  相似文献   

Working with the new generation of interactive media technologies in schools: CD-I and CDTV     

Lydia Plowman  Philip Chambers 《British journal of educational technology : journal of the Council for Educational Technology》1994,25(2):125-134

A preliminary evaluation of classroom use of CD-I and CDTV in five schools is described. Information is provided on the pedagogical, operational, and logistical characteristics of these interactive media technologies compared to interactive video. A number of benefits are described, but it is suggested that poorly designed or inappropriate software and technology fatigue amongst teachers contribute to the low take-up of these systems in the classroom.  相似文献
