Effects of resource concentration on research performance

This paper reports the results of a study commissioned by the Australian National Board of Employment, Education and Training, which examines in detail the effect of resource concentration on research performance, and the basis for critical mass, economies of scale, critical time and risk strategy hypotheses. The widespread introduction of policies of resource concentration around the world are found to have been based on little examined assumptions, and in operation to be at times counter-productive. In general relationships between group size and productivity are found to be linear, though there does appear to be evidence for an optimal size of 5–8. Detailed results and policy implications of these findings are presented.     

What do we know about deaf clients after thirteen years of ambulatory mental health care? An analysis of the PsyDon database, 1987-1999

Little is known about demographic, deafness-related, and diagnostic characteristics of deaf and partially hearing people with psychosocial or psychiatric problems. A study was conducted derived from data from intake assessment interviews of people with hearing loss treated at a Dutch ambulatory mental health center for the deaf between 1987 and 1999. Both sexes were equally represented. People who were postlingually deaf, hard of hearing, below age 22 years, or above age 65 years were less likely to ask for help than other groups in the study. Men presented more psychiatric disorders, and women more psychosocial problems, especially partially hearing women. The authors recommend stronger emphasis on mental health care for postlingually deaf people, severely hard of hearing people, adolescents, and retirement-age people. They also recommend development of skills for rational and emotional self-expression in the education and rearing of children with hearing loss.     

Children's Moral Reasoning about Family and Peer Violence: The Role of Provocation and Retribution

Several theories assume that the approval of violence is related to deficits in moral reasoning. However, this assumption has rarely been empirically tested. This inquiry examined violent and nonviolent children's moral reasoning about violence in family and peer situations. 108 subjects (54 violent and 54 nonviolent, aged 8–1, 10–2, 12–2) selected from 2 inner city schools were asked to evaluate unprovoked and provoked violent situations. All the children condemned unprovoked violence using moral reasoning. With provoked situations, the violent group focused more on the immorality of the provocation and perceived "hitting back" as a form of reciprocal justice. The nonviolent group perceived "hitting" worse than the psychological harm of the provocation and condemned the violence. The results suggest that both the approval and disapproval of violence were justified by moral reasoning. It was proposed that the violent children's greater focus on psychological provocations may be due to experiences and self-perceptions of victimization.     

The impact of word processing on the preparation and submission of written essays in a tertiary course of study

This study investigated whether the use of word processing in the creation and submission of written essays by tertiary students, resulted in the achievement of higher grades compared with conventional methods. The study was conducted among 240 student teachers in the first year of a degree course and studying a pre-service unit in teacher education. Students' marks in an essay were gathered along with details of the submission method used; word processed, typed or hand-written. Initial statistical tests showed that students who used word processing as a method for essay submission scored significantly higher essay marks that students whose essays were typed or hand-written. Further tests, however, revealed than it was the level of revision carried out rather than the submission method that accounted for the differences in achieved scores.     

Human and machine diagnosis of scientific problem-solving abilities

Diagnosis of the problem-solving state of a novice student in science, by an accomplished teacher, is studied in order to build a computer system that will simulate the process. Although such “expert” systems have been successfully developed in medicine (MYCIN, INTERNIST/CADUCEUS), very little has been accomplished in science education, even though there is a reasonably close parallel between expert medical diagnosis of patients with physiological problems and expert instructional diagnosis of students with learning problems. The system described in this paper, DIPS: Diagnosis for Instruction in Problem Solving, involves a new line of research for science educators interested in interdisciplinary efforts and ways in which computer technology might be used to better understand how to improve science learning. The basic architecture of the DIPS system is outlined and explained in terms of instruction and research implications, and the role of such “intelligent” computer systems in science education of the future is considered.     

Didactic use of concept mapping in higher education: applications in medical education

This paper describes the use of concept mapping for didactic purposes in higher education at the university level, namely, in medical schools. The first study involved the use of concept mapping to evaluate students' self learned knowledge of subject matter during their clerkship in a department of surgery. The individually constructed cognitive maps facilitated learning by being used in group discussions with the tutor, to identify correct ideas as well as misconceptions, and to convey the tutor's view, and thereby facilitated learning. The second, unrelated study employed concept mapping to evaluate an inservice Orientation Workshop for medicine school faculty. The cognitive structure characteristics of the participants and their congruence with those of the workshop teachers were assessed. These provided evidence regarding the attainment of the workshop's objectives for different kinds of participant. For example, by using concept mapping in planning instruction or preparing materials for teaching, teachers become learners. Potential didactic uses in higher education are discussed in light of these studies.     

Physical Education Pre-service Teachers’ Understanding,Application, and Development of Critical Thinking

To better prepare physical education (PE) teachers, this study explored a group of pre-service teachers’ understanding, application, and development of critical thinking (CT) in a capstone methods course. Participants were 12 pre-service teachers from a PE teacher education (PETE) program at a large university in the southwestern United States. Data were collected through focus group interviews and post-lab assignments and were analyzed via content analysis. Findings showed that the PE pre-service teachers could define CT and recognize its importance to teaching and learning. Together with field-based teaching practices, course written assignments such as the encyclopedia article, curriculum project, lesson plans, and post assignments were identified as contributors to CT development. At the end of the semester, the PE pre-service teachers demonstrated an improvement in CT across three levels. Based on our findings, we recommend the integration of CT instruction into PETE programs.
