Benefits of sign language interpreting and text alternatives for deaf students' classroom learning

Four experiments examined the utility of real-time text in supporting deaf students' learning from lectures in postsecondary (Experiments 1 and 2) and secondary classrooms (Experiments 3 and 4). Experiment 1 compared the effects on learning of sign language interpreting, real-time text (C-Print), and both. Real-time text alone led to significantly higher performance by deaf students than the other two conditions, but performance by deaf students in all conditions was significantly below that of hearing peers who saw lectures without any support services. Experiment 2 compared interpreting and two forms of real-time text, C-Print and Communication Access Real-Time Translation, at immediate testing and after a 1-week delay (with study notes). No significant differences among support services were obtained at either testing. Experiment 3 also failed to reveal significant effects at immediate or delayed testing in a comparison of real-time text, direct (signed) instruction, and both. Experiment 4 found no significant differences between interpreting and interpreting plus real-time text on the learning of either new words or the content of television programs. Alternative accounts of the observed pattern of results are considered, but it is concluded that neither sign language interpreting nor real-time text have any inherent, generalized advantage over the other in supporting deaf students in secondary or postsecondary settings. Providing deaf students with both services simultaneously does not appear to provide any generalized benefit, at least for the kinds of materials utilized here.     

OTseeker helps library and allied health professionals to find quality evidence efficiently

Background: Research is essential for evidence‐based practice yet many health professionals do not have enough time to find research. Studies relevant to occupational therapists can be particularly difficult to find. Most search engines are broad and return a large number of irrelevant articles. Occupational Therapy Systematic Evaluation of Evidence (OTseeker) is an occupational therapy database available at http://www.otseeker.com . Developed by Australian occupational therapists, the resource aims to increase access to research and support clinical decision making. This discipline‐specific database contains pre‐appraised information from a variety of sources and decreases the time required to locate best evidence. Objectives: The aims of this paper are to: (i) describe how health librarians can use OTseeker to help allied health students, researchers and practitioners, particularly in occupational therapy, to find quality evidence; (ii) provide a teaching resource for health librarians based around the OTseeker evidence database; and (iii) highlight new features contained on the OTseeker database. Methods: A case study is provided which focuses on searching for evidence on the effectiveness of upper limb rehabilitation after stroke using OTseeker. Conclusion: This paper may increase the knowledge, skills and competencies of health librarians, helping them to access evidence‐based databases, and educate other professionals.     

Differences in community colleges’ missions: Evidence from California

Using data for 108 colleges in the California Community College System, this paper poses two questions. First, do California community colleges differ in their missions? Second, if they do, can inter-college differences in missions be explained? We address the first question by developing college-specific measures of curriculum mix, which we use to characterize colleges as to their curriculum emphases and specializations. We find that colleges differ in the extent to which they offer a transfer specialization or a nontransferable voc-ed specialization. Turning to the second question, we attempt to explain inter-college differences in curriculum emphasis and specialization with institutional variables including student demographics, labor market characteristics, and community characteristics. While not strong, we view our results as suggesting that curriculum emphases and specializations are related to student demographics and community needs.     

Exploring the relationship between K-8 prospective teachers’ algebraic thinking proficiency and the questions they pose during diagnostic algebraic thinking interviews

In this study, we explored the relationship between prospective teachers’ algebraic thinking and the questions they posed during one-on-one diagnostic interviews that focused on investigating the algebraic thinking of middle school students. To do so, we evaluated prospective teachers’ algebraic thinking proficiency across 125 algebra-based tasks and we analyzed the characteristics of questions they posed during the interviews. We found that prospective teachers with lower algebraic thinking proficiency did not ask any probing questions. Instead, they either posed questions that simply accepted and affirmed student responses or posed questions that guided the students toward an answer without probing student thinking. In contrast, prospective teachers with higher algebraic thinking proficiency were able to pose probing questions to investigate student thinking or help students clarify their thinking. However, less than half of their questions were of this probing type. These results suggest that prospective teachers’ algebraic thinking proficiency is related to the types of questions they ask to explore the algebraic thinking of students. Implications for mathematics teacher education are discussed.     

The Relationships Among Generativity,Values, Individual Differences,and Commitment to an Ideal Vision

Kaufman ( 2006a , 2011 ) defines Ideal Visions as measurable statements of the kind of world an organization, as well as its associates and external stakeholders, commits to help create for the future. This study investigated the relationships among several research‐supported variables regarding personality aspects and individual characteristics with indicators of individuals’ motivation to achieve goals aimed at adding value to external clients and society. Indicators of generative beliefs, values, individual differences, and commitment to an Ideal Vision were examined in this study. Generativity (the concern in establishing and guiding the next generation), membership and activity in a formal civic organization, and gender, each demonstrated a statistically significant relationship with commitment to an Ideal Vision. In addition, various values were ranked differentially by those with relatively high versus low commitment to an Ideal Vision. A discussion of how these variables warrant the ongoing investigation into these variables is provided.     

Mind the gap! Students’ use of exemplars and detailed rubrics as formative assessment

The current study examined efficient modes for providing standardized feedback to improve performance on an assignment for a second year college class involving writing a brief research proposal. Two forms of standardized feedback (detailed rubric and proposal exemplars) were utilized is an experimental design with undergraduate students (N = 100) at three urban college campuses. Students completed a draft of a proposal as part of their course requirements and were then randomly assigned to receive a detailed rubric, proposal exemplars, or a rubric and proposal exemplars for use in revising their work. Analyses of students’ writing from first draft to second draft indicated that all three conditions led to improvements in writing that were significant and strong in terms of effect size, with the stand-alone detailed rubric leading to the greatest improvement. Follow-up focus groups with students indicated that a stand-alone rubric potentially engages greater mindfulness on the part of the student. Practical implications are discussed.

The weather was perfect that July day in the San Juan Islands of Washington-warm sunshine, blue skies, and water like glass. I was working as a naturalist on a whale-watch boat, describing behaviors of the orcas we were following.     

Mental health services for people who are deaf

The issue of mental health services available to adults and children in the United States who are deaf is addressed. Included is a historical perspective on the changes in these services over the last 50 years. Within this scope, the current status of services is described in some detail. Psychological research on children who are deaf is reviewed, and current issues faced by school psychology and psychologists who evaluate deaf children in school settings are examined. The disturbing current trend toward the criminalization of people with mental illness, which affects both hearing and deaf adults with psychiatric diagnoses, is covered. Suggestions are made for improving mental health services for children and adults who are deaf.     

The geometric module in the rat: independence of shape and feature learning in a food finding task

Rats found food in a rectangular enclosure in three experiments testing how learning about a distinctive feature near a goal interacts with learning based on the geometry of an enclosure. Rats trained to follow a feature in square and triangular enclosures and to use geometry in the rectangle followed the feature when it was in the rectangle (Experiment 1). Rats trained with the feature in a geometrically consistent corner of the rectangle learned about both geometry and the feature (Experiment 2). Training with the feature in the square did not block learning of geometry when both predicted the location of food in the rectangle (Experiment 3). The “geometric module” (Cheng, 1986) may have a special status in spatial learning.     

Cognitive complexity,the first year of teaching,and mentoring

Drawing on data from a US study of nine mentors and mentees, including mentee scores on the Reasoning about Current Issues (RCI) Test, which offers a measure of cognitive complexity, the authors explore how differences in cognitive complexity were related to role expectations, conceptions of teaching problems, and the use of evidence for justifying beliefs. Growing out of the Reflective Judgment Model developed by King and Kitchner [(2002). The reflective judgment model: Twenty years of research on epistemic cognition. In B. Hofer, & P. Pintrich (Eds.), Personal epistemology: The psychology of beliefs about knowledge and knowing (pp. 37–61). Mahwah, NJ: Lawrence Erlbaum Associates] the RCI defines cognitive complexity in terms of how individuals reason—make judgments and use evidence—about ill-structured, controversial, problems. The authors argue that differences in how individuals reason when problem solving may help explain some aspects of how relationships between mentees and mentors form and suggest that greater attention needs to be given to cognitive complexity when designing induction and mentor programs.
