Range effects using instrumental choice procedures

Pigeons were trained to discriminate visual flicker-rate stimuli using two types of instrumental choice procedures. One experiment used a free-operant concurrent schedule with multiple schedule components. Two additional experiments used a two-alternative, discrete-trial procedure. In all experiments, the range of training stimuli was manipulated across conditions. Results from all three experiments showed typical range effects on discrimination performance. That is, performance declined with increases in the overall range of variation of training stimuli. These range effects occurred with either continuous response rate measures or discrete choice measures. Moreover, range effects appeared with relatively high or low levels of overall discrimination accuracy and with either symmetrical or asymmetrical extensions of stimulus range. The results of these experiments suggest that increasing stimulus range influences both perceptual sensitivity and bias to response alternatives.     

Metacognition and EFL/ESL reading

Several distinct research streams are converging in the field of foreign or second language reading in the U.S. Separate research streams in metacognition, in reading strategies, and in the training of reading strategies are converging in the field of English as a foreign or second language. This confluence of research is dramatically impacting the teaching of English to adult non-native speakers for academic purposes. In this article we will briefly review these distinct research streams for their relevance to the population in question, and will then describe the research design for an empirical study we are currently conducting to further investigate the efficacy of metacognitive strategy training for adult EFL/ESL reading.     

STUDENT ATTITUDES TOWARD AFFIRMATIVE ACTION IN COLLEGE ADMISSIONS

Using a national sample of over 277,850 collegefreshmen, this study examines attitudes towardaffirmative action in college admissions separately forfour racial/ethnic groups: whites/Caucasians,African-Americans, Asian-Americans, and Mexican-Americans. Foreach group, analyses address the extent to whichopposition to affirmative action is driven by factorssuch as self-interest, political ideology, and attitudes about race/ethnicity. Findings suggest somedifferences in how these factors operate acrossdifferent racial/ethnic groups.     

Best practices in gifted identification and assessment: Lessons from the WISC-V

School psychologists in today's schools have the unique opportunity—and responsibility—to guide identification for gifted programs. “Who is gifted?” remains a perennial question in the gifted education literature, not answered by group intelligence screeners that purportedly level the playing field for all. As the student body grows more diverse, there is increasing necessity to ensure that all students have equal access to gifted programs. Failure to identify and develop the advanced abilities of gifted children who are culturally diverse, economically deprived, highly gifted, or twice exceptional is justifiably viewed as a civil rights violation. The National Association for Gifted Children's 2018 position statement, “Use of the WISC-V for Gifted and Twice Exceptional Identification,” offers important considerations for identifying the gifted. Based on a national research study of 390 gifted children on the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V), the statement recommends that the traditional practice of mandating Full Scale intelligence quotient scores be abandoned. Instead, it embraces the use of any one of six expanded index scores that are better measures of abstract reasoning for selecting students for gifted provisions. As gifted children are oftentimes asynchronous, alternate index scores are less biased and better able to document the strengths of all gifted children. What is learned from the WISC-V can be applied by school psychologists to improve the choice of comprehensive individual intelligence tests, brief intelligence tests, and the body of evidence gifted children must exhibit.     

Adopting a toolkit to manage time,resources, and expectations in the systematic review process: a case report

Background:The proliferation of systematic reviews has impacted library operations and activities as librarians support, collaborate, and perform more tasks in the systematic review process. This case report describes a toolkit that librarians with extensive experience in supporting multiple review teams use to manage time, resources, and expectations in the systematic review process.Case Presentation:The toolkit is a compilation of documents that we use to effectively communicate with and help review teams understand and navigate each stage of the systematic review process. Elements included in the toolkit and discussed in this case report are intake forms, communication templates and memoranda, a process flow diagram, library guides on tools for retrieval and data appraisal, and established standards for guidance during the write-up stage. We describe the use of the toolkit for both education and project management, with a focus on its use in helping manage team time, resources, and expectations.Discussion:The systematic review toolkit helps librarians connect systematic review steps and tasks to actionable items. The content facilitates and supports discussion and learning by both librarians and team members. This toolkit helps librarians share important information and resources for each stage of the process.     

Blood Pressure,Fitness, and Lipid Profiles of Rural Women in the Wellness for Women Project

Purpose: This study examined whether rural women, who had a high prevalence of prehypertension and hypertension upon enrollment in a wellness program, would also have a high prevalence of other cardiovascular disease risk factors such as low fitness and/or dyslipidemia. Methods: Data were analyzed from 225 rural women, ages 50-69, enrolled in a healthy eating and activity clinical trial. Cardiovascular health histories, fitness measures, blood pressure, and fasting blood serum samples were collected following standardized protocols at rural research offices. Chi-square and MANOVA were performed to examine differences in health characteristics, lipids, and fitness across blood pressure categories. Results: Fitness indicators of estimated VO_2max, 1-mile walk time, and resting heart rate differed between the blood pressure groups, with those in the prehypertensive and hypertensive groups having less desirable profiles than those in the normotensive group. Triglyceride levels of 150 mg/dL or greater, were observed in 36%, 32%, and 16.7% of women who had hypertensive, prehypertensive, and normal blood pressures, respectively. Conclusions: The need for routine blood pressure screenings by practitioners is reinforced by finding that rural women screened via PAR-Q and/or physician clearance had a high prevalence of prehypertensive and hypertensive blood pressures, in addition to low fitness and nonoptimal triglycerides. Practitioners need to provide counselling based on results and refer to other providers as appropriate.Key Words: blood pressure, lipids, fitness, rural women     

Re-conceptualizing partnerships across the teacher education continuum

This research, funded by the Economic and Social Research Council–Teaching and Learning Research Programme (ESRC–TLRP), explored student and beginning teachers' experiences of teacher education in Northern Ireland. Within a situation of teacher over-supply, many newly qualified teachers have little or no induction. This paper focuses on the views of key induction providers on the effectiveness of partnership arrangements. These stakeholders believed that an improved model of partnership was needed, particularly for induction, and a more collegial model could offer a positive reconceptualisation of early teaching experience enabling reciprocal professional learning.     

A framework for conducting research on collaborative teacher education

The purpose of this paper is to propose a framework for conducting research on teacher education programmes that practise collaboration between special and general education faculty to advance inclusion. Such a framework can establish a common language for collaborative teacher education and provide a structure for conducting research on individual programmes as well as cross-site comparisons. It is based on the assumption that collaboration represents a robust, systematic integration of special and general education across all aspects of the preservice curriculum. The proposed framework includes three collaborative program models and five programme dimensions.     

Bridging the Gap Between the Language of Science and the Language of School Science Through the Use of Adapted Primary Literature

In this paper we make the case that the language of school science and the language of science are widely divergent. We trace the divergence to a simple view of reading that prevails not only in science education but in most of schooling. Based upon the importance of language in science and the role of language in capturing the essential nature of scientific reasoning, we conclude that conceiving of reading as a form of inquiry could assist in bringing the two languages more into alignment. We recommend the use of adapted primary literature as one curriculum and instruction innovation that can be useful in illustrating the nature of reading as inquiry.
