The central purposes of this study were to review the development and evolution of the Scientific Attitude Inventory (SAI) and then reevaluate the psychometric properties of the revised form of the SAI, the Scientific Attitude Inventory II (SAI‐II). The SAI‐II was administered to a convenience sample of 543 middle and high school students from five teachers in four schools in four school districts in San Antonio, Texas, at the beginning of the 2004–2005 school year. Confirmatory factor analysis on the full data set failed to support the existence of a 12‐factor structure (as proposed by the scale developers) or a one‐factor structure. The data were then randomly divided into exploratory [exploratory factor analysis (EFA)] validation and confirmatory [confirmatory factor analysis (CFA)] cross‐validation sets. Exploratory and confirmatory models yielded a three‐factor solution that did not fit the data well [χ² (321) = 646, p < .001; RMSEA = .061 (.90 CI = .054–.068); and CFI = .81]. The three factors were labeled “Science is About Understanding and Explaining” (13 items), “Science is Rigid” (6 items), and “I Want to Be a Scientist” (8 items). The α‐coefficients for these three factors ranged from 0.59 to 0.85. Whether these identified subscales are valid will require independent investigation. In this sample, and consistent with prior publications, the SAI‐II in its current form did not have satisfactory psychometric properties and cannot be recommended for further use. © 2008 Wiley Periodicals, Inc.

Toward an Expanded Concept of Rhetorical Delivery: The Uses of Reports in Public Policy Debates     

Carolyn D. Rude 《Technical Communication Quarterly》2004,13(3):271-288

Preparing students for civic engagement requires new knowledge about the uses of documents for advocacy and social change. Substantial social change results from repeated rather than from single rhetorical acts. Reconsideration of the rhetorical canon of delivery suggests expanding the concept beyond its present connection to publication (visual design, medium) to a rhetorical situation comprehensively defined. Delivery may take place over time and embrace a web of activities including field work, updates, and interconnections with other publications.  相似文献

DNA microarray wet lab simulation brings genomics into the high school curriculum   总被引：1，自引：1，他引：0  

Campbell AM  Zanta CA  Heyer LJ  Kittinger B  Gabric KM  Adler L  Schulz B 《CBE life sciences education》2006,5(4):332-339

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula.  相似文献   

Evaluation of a University‐Based Mentoring Program: Mentors’ Perspectives on a Service‐Learning Experience     

Carolyn Hughes  Elizabeth Boyd  Sara J. Dykstra 《Mentoring & Tutoring: Partnership in Learning》2013,21(4):361-382

Researchers in the educational field have investigated how a caring adult can best provide mentoring support to youth placed at risk and what functions a mentoring program should serve to promote healthy mentoring relationships. However, the perspective of mentors rarely has been sought to elicit their evaluation of a mentoring program or recommendations for programmatic change. The purpose of this article was to investigate the views of university students serving as mentors in high‐need high schools or community centers. We asked 49 students, primarily undergraduates across a range of liberal arts disciplines, who were participating in a university‐based service‐learning mentoring program for youth attending high‐poverty high schools: (a) what activities they engaged in with mentees, (b) how they benefited from the mentoring program, and (c) how they perceived the program and what recommendations they had for change. Findings revealed specific suggestions that mentoring program coordinators can adopt to address mentors’ concerns and promote sustained, durable mentoring relationships for youth.  相似文献   

The effect of music therapy services on classroom behaviours of newly arrived refugee students in Australia—a pilot study     

Felicity Baker  Carolyn Jones 《Emotional and Behavioural Difficulties》2013,18(4):249-260

This pilot study examined the effects of a short‐term music therapy program on the classroom behaviours of newly arrived refugee students who were attending an intensive ‘English as a Second Language’ secondary school. A cross‐over design with two five‐week intervention periods was employed with group music therapy sessions conducted one or two times per week. Data from the Behaviour Assessment Scale for Children were used to evaluate a range of positive and negative school behaviours. A significant decrease in externalising behaviours was found with particular reference to hyperactivity and aggression. No significant differences were found in other behaviours. Explanations and implications of these findings are discussed.  相似文献   

Incompatible Rhetorical Expectations: Julia W. Carpenter's Medical Society Papers, 1895–1899     

Carolyn Skinner 《Technical Communication Quarterly》2013,22(4):307-324

This article examines 3 papers presented before the Cincinnati Academy of Medicine by 19th-century physician Julia W. Carpenter. The article identifies 3 strategies Carpenter used to negotiate the incompatible rhetorical expectations for women and for physicians. The published records of academy discussions provide evidence for Carpenter's colleagues' reactions to each strategy, revealing the complexity of her rhetorical situation and demonstrating the complex links among rhetorical practice, professional identity, and a communicator's social position.  相似文献   

How Can Community Colleges Better Serve Low-Income Single-Mother Students? Lessons From the For-Profit Sector     

Carolyn Arcand 《Community College Journal of Research & Practice》2013,37(12):1187-1191

Low-income single-mother students are disproportionately choosing to attend for-profit schools over community colleges when pursuing associate’s degrees and subbaccalaureate certificates. For-profit schools offer single mothers juggling school, employment, and family the benefits of accelerated degree programs along with enhanced convenience and streamlined student services. Community colleges can become a more appealing and feasible option for low-income single-mother students by adopting some of these characteristics while concurrently advertising their relative affordability and high level of academic rigor.  相似文献
