Predictors of academic success in medical school

This study was designed to determine the predictive validity of selected admissions variables used by the University of Kentucky College of Medicine. Data for the study were collected from 586 students admitted to the M.D. program from 1961 to 1968. These students were categorized into one of three groups (Successful [SUCC], Successful with Extended Study [SWES], and Lost to Medicine [LTM]) based upon their performance in medical school. A two-way analysis of variance and the use of a post hoc Scheffé method of multiple comparisons indicated significant differences between the SUCC group and the combined SWES and LTM groups. Therefore, the data revealed the predictive ability of two admissions variables and suggested the need for additional research into the subjective variables used in the admissions process.     

DEVELOPING AND USING INTERDISCIPLINARY CASE STUDIES IN TEACHING GERIATRICS TO PRACTICING HEALTH CARE PROFESSIONALS

Continuing education programs for health care professionals who practice in geriatrics are an important part of improving the health care provided to older adults. Programs utilizing active forms of learning that mimic the clinical environment are more successful at changing the behavior of health care professionals than traditional didactic styles of teaching. Problem-based learning methods allow learners to identify their own areas of strength and weakness and to work toward improvement in a manner best suited to their needs. This article describes an interdisciplinary team of educator-clinicians in geriatrics who developed clinical case studies embodying these approaches as one method of improving the learning process for adult health care providers. An actual sample case study is presented as an illustration of the principles embodied in this process. Lessons learned from the development and use of these case studies are summarized in the context of improving the quality of continuing education programs for health care professionals in geriatric practice.     

Using National Education Longitudinal Data Sets in School Counseling Research

National longitudinal databases hold much promise for school counseling researchers. Several of the more frequently used data sets, possible professional implications, and strategies for acquiring training in the use of large‐scale national data sets are described. A 6‐step process for conducting research with the data sets is explicated: determining research questions, accessing the data set, understanding the study's sample design, determining an analytic sample, considering pertinent data analysis issues, and understanding the limitations of using the data sets. Suggestions for preparing school counseling researchers and potential themes for future research are outlined.     

Examining the capacity of a sport for development programme to create social capital

Robert Putnam’s conceptualization of social capital has been commonly associated with, and used to analyse, sport-for-development programmes. This paper bucks this trend and uses James Coleman’s rational strain of social capital to examine the use of sport as a component part of a programme to support male adults in addressing connected problems of substance misuse, homelessness and other forms of social exclusion. Using a qualitative research strategy, in-depth and longitudinal data were collected using individual interviews and focus groups with programme participants and key stakeholders over a three-year period. The results suggest the importance of unintentionality for the formation and use value of social capital; indicating that social capital created through this programme was individual, contingent on interactional context and benefited individuals in line with Coleman’s six aspects of social capital.     

Preparing beginning teachers for inclusion: designing and assessing supplementary fieldwork experiences

Inclusive education requires restructuring educational provision so that mainstream schools are able to provide for the needs of all students in their communities. To help realise this goal, initial teacher education programmes need to better prepare new graduates for teaching students with complex special education needs, including students with intellectual disability. Concerns about the capacity of current school-based placements to prepare new teachers for inclusive classrooms have led some teacher education institutions to develop supplementary fieldwork experiences. The current study involved an investigation into such an experience and looked at the benefits to pre-service teachers (PSTs) of tutoring a young adult with intellectual disability. The findings indicate that PSTs learned effective strategies for differentiating a programme of work and, in their first year of study, were developing a teacher identity. The importance of aligning experiences with coursework units is highlighted and the need for valid assessments of how well initial teacher education programmes are preparing beginning teachers for inclusion, and what these assessments may look like, is discussed.     

Validation of a single-stage submaximal treadmill walking test

Abstract

The single-stage treadmill walking test of Ebbeling et al. is commonly used to predict maximal oxygen consumption ([Vdot]O_2max) from a submaximal effort between 50% and 70% of the participant's age-predicted maximum heart rate. The purpose of this study was to determine if this submaximal test correctly predicts [Vdot]O_2max at the low (50% of maximum heart rate) and high (70% of maximum heart rate) ends of the specified heart rate range for males and females aged 18 – 55 years. Each of the 34 participants completed one low-intensity and one high-intensity trial. The two trials resulted in significantly different estimates of [Vdot]O_2max (low-intensity trial: mean 40.5 ml · kg^?1 · min^?1, s = 9.3; high-intensity trial: 47.5 ml · kg^?1 · min^?1, s = 8.8; P < 0.01). A subset of 22 participants concluded their second trial with a [Vdot]O_2max test (mean 47.9 ml · kg^?1 · min^?1, s = 8.9). The low-intensity trial underestimated (mean difference = ?3.5 ml · kg^?1 · min^?1; 95% CI = ?6.4 to ?0.6 ml · kg^?1 · min^?1; P = 0.02) and the high-intensity trial overestimated (mean difference = 3.5 ml · kg^?1 · min^?1; 95% CI = 1.1 to 6.0 ml · kg^?1 · min^?1; P = 0.01) the measured [Vdot]O_2max. The predictive validity of Ebbeling and colleagues' single-stage submaximal treadmill walking test is diminished when performed at the extremes of the specified heart rate range.     

Creativity, Mathematizing, and Didactizing: Leen Streefland's work continues

This reaction to the papers in this PME Special Issue of Educational Studies in Mathematics draws a wider perspective on the issues addressed and some of the constructs used in research in Realistic Mathematics Education (RME). In particular, it tries to show that while the problems addressed existed within the world-wide arena of mathematics education and were not unique to the Dutch educational system, the methods used at the Freudenthal Institute to address them were uniquely adapted to that system yet foreshadowed developments in the wider field of mathematics education. The predictive aspects of mathematizing, didactizing, and guided reinvention, in which models-of become models-for on various levels, resonate with trends in mathematics education in recent years, including those promoted by the National Council of Teachers of Mathematics in the USA. Research methodologies, too, have broadened to include more humanistic qualitative methods. Developmental research as epitomized in the RME tradition makes the distinction between quantitative and qualitative research obsolete, because there is no restriction on research methods that may be useful in investigating how to improve the teaching and learning of mathematics, and in the designing of mathematics curricula. Thus some aspects of this research resonate with what have come to be known as multitiered teaching experiments. However, in RME there is also a special content-oriented didactical approach that harmonizes with an emphasis on didactics (rather than pedagogy)in several other European countries. Some implications are drawn for future research directions. This revised version was published online in August 2006 with corrections to the Cover Date.     

The relative impact of violation type and lie severity on judgments of message deceitfulness

This paper is part of a larger program of research assessing variables that underlie quantitative deceptiveness ratings. Several recent theoretical approaches, including Information Manipulation Theory (IMT), propose that deceptive messages are best understood as varying along two or more dimensions. At the same time, researchers have increasingly moved from dichotomous deception judgments to continuous deception ratings. This paper questions the validity of scaling degrees of deceptiveness along a single dimension, and argues that gradations in perceived deceptiveness reflect both the type of information manipulated and the severity of the consequences of the deception. This reasoning was tested with alxl experiment (N = 236) in which both the type of information manipulated and the severity of the consequences were systematically varied. As predicted, the results suggest that false messages (i.e., quality violations) are rated as more deceptive than lies of omission (i.e., quantity violations) when lie severity is low, but this difference diminishes as lie severity increases. In other words, false messages were rated as deceptive regardless of severity, but messages omitting information were rated as deceptive as false messages only when the consequences were serious. The implications for measuring deception are discussed.
