Human Performance Technology: An Examination of Definitions through Dependent and Independent Variables

This definitional paper provides a chronological perspective of human performance technology (HPT) definitions and an evaluation of them in terms of independent and dependent variables. The intent is to compare the definitions with the goals that have been articulated for HPT over the years and to provide one source for past definitions as researchers move forward to continue their study of HPT. The search for definitions extended back to Gilbert in the late 1970s, who provided a foundation; the search revealed an evolution of definitions from the late 1970s to the present day, with the definition currently on the Website of the International Society for Performance Improvement (ISPI). The analysis depicts a brief chronology of the field, the breadth of HPT through the definitions, and how the definitions changed as the field matured (with the increased knowledge and applications of several theory disciplines).     

Diversity and inclusivity at university: a survey of the experiences of lesbian,gay, bisexual and trans (LGBT) students in the UK

The extent to which UK universities are ‘gay friendly’ has received some attention in the press. Whilst there are a number of published studies exploring campus climate for lesbian, gay, bisexual and trans (LGBT) students and/or staff, these are primarily localised studies undertaken in State Universities and Baccalaureate Colleges in the US. The present study is a nationwide UK study of campus climate, based on survey data collected from a sample of 291 LGBT students from 42 universities across the UK. The findings show that despite the increased implementation of an equality agenda (e.g. equal access; widening participation) in UK Higher Education, homophobia on campus is still a significant problem and therefore universities are not perceived nor experienced by LGBT students as ‘safe spaces’ in which to be open about sexual orientation/gender identity. The implications of the findings for university policy and practice in relation to LGBT (and indeed all) students is also explored.     

Gendered perceptions of typical engineers across specialties for engineering majors

Young women do not choose to be engineers nearly as often as young men, and they tend to cluster in particular specialties when they do. We examine these patterns and the role of gender schemas as applied to perceptions of typical engineers in understanding the choices that women make in terms of engineering specialties. We use Part 1 of two waves of survey data collected from first-year engineering students at a large Midwestern university in the fall of 2014. Respondents scored typical engineers on 60 items from the Bem Sex-Role Inventory [Bem, S. L. 1974. “The Measurement of Psychological Androgyny.” Journal of Consulting and Clinical Psychology 42: 155–162]. Preliminary results show that women consider the typical engineer to be more masculine compared to the impressions gathered from men. Additionally, engineering gender schemas predict some specialty areas but not all, suggesting that gendered perceptions may not affect choice of specialty. Our results provide insight into the decisions that women make once entering engineering.     

Using an R shiny to enhance the learning experience of confidence intervals

Many students find understanding confidence intervals difficult, especially because of the amalgamation of concepts such as confidence levels, standard error, point estimates and sample sizes. An R Shiny application was created to assist the learning process of confidence intervals using graphics and data from the US National Basketball Association.     

A Comparison of Knowledge Obsolescence of Graduating Seniors and Practitioners in the Field of Physical Education

Abstract

The issue of defining and measuring professional obsolescence among physical educators is examined through a comparison of the current knowledge base of graduating physical education seniors and physical education practitioners in Pennsylvania. In a previous study, the “Inventory of Recent Knowledge in Physical Education,” a 260-item sample of current knowledge as defined by content experts was developed by the authors and administered by mail to the population of 2,737 male professional members of the public school districts' departments of physical education in Pennsylvania. In the present study, results from the first study were compared with those from an administration of the same instrument to 462 female and male physical education majors graduating from nine Pennsylvania higher education institutions. Both studies employed multiple-matrix procedures for item-person sampling and data analysis. An analysis of the results for both groups showed essentially similar performance profiles on the Inventory. Average scores of the two groups tended to be low and neither met preestablished minimum standards for defining up-to-date or nonobsolete performance. These results point to a clear conflict between what experts think up-to-date persons in the field of physical education should know and the knowledge performance of practitioners and students.     

Cardiovascular fitness and haemodynamic responses to maximal cycle ergometer exercise test in children 6–8 years of age

Abstract

We investigated cardiovascular fitness and haemodynamic responses to maximal cycle ergometer exercise test in children. The participants were a population sample of 425 children (204 girls, 221 boys) aged 6–8 years. Heart rate (HR) and systolic blood pressure (SBP) were measured from the beginning of pre-exercise rest to the end of recovery period. We provided reference values for peak workload and changes in HR and SBP during and after maximal exercise test in girls and boys. Girls had a lower cardiovascular fitness, indicated by peak workload per body weight [mean (2 s) 2.7 (0.9) vs. 3.1 (1.0) W · kg^–1, P < 0.001] and lean mass [mean (2 s) 3.5 (0.9) vs. 3.8 (1.0) W· kg^–1, P < 0.001] than boys. Plateau or decline in SBP close to the end of the test was found in about third of children and was considered a normal SBP response. Girls had a slower HR decrease within 2 min after the test than boys [mean (2 s) 53 (18) vs. 59 (22) beats · min^–1, P < 0.001]. The results are useful for physicians and exercise physiologists to evaluate cardiovascular fitness and haemodynamic responses to exercise in children and to detect children with low exercise tolerance or abnormal haemodynamic responses to exercise.     

Accuracy of a Perspective Control Lens

Abstract

The contextual interference (CI) effect has been replicated many times since its first demonstration by Shea and Morgan (1979) in the motor learning domain (see Brady, 1998; Magill&;Hall, 1990). The CI effect is characterized by the observation that experiencing greater interference during acquisition is detrimental to immediate performance but enhances delayed performance as measured on retention or transfer tests. High CI is most often created by random practice in which the learning of multiple tasks occurs in a single training. In contrast, low CI is frequently created by using a blocked practice format in which all the practice trials of one task are completed before another task is introduced. One theoretical account that has been forwarded to account for the CI effect is labeled the action plan reconstruction hypothesis (Lee&;Magill, 1983, 1985). This position intimates that before a movement occurs an “action plan” must be prepared. In blocked practice, a previously prepared “action plan” is readily available from trial to trial, but it suffers from lack of attention on trials following initial retrieval from working memory. In random practice, however, each time a task must be executed a “reconstruction” of the action plan must be processed, because the interchange of information from trial to trial never allows the same information to remain in working memory for an extended amount of time. Presumably, the additional trial-to-trial preparation used by the random practice participant during practice results in a more resilient memory representation that better supports long-term recall efforts compared to their blocked practice counterparts.     

The Use of Television in Public Examinations

This paper analyses the use of a television film, David Leland's Flying into the Wind, in O Level English Literature examinations in 1986. This is the first use of television material in an examination of this kind. After studying the video as part of a two‐year course, candidates were shown part of the television film during the examination and asked to comment upon it. An analysis of candidates' responses suggests television is a suitable medium for use in public examinations, as well as a popular choice with the candidates themselves. Certain aspects of the candidates' responses suggest the importance of visual imagery, and this in turn may have implications for theories concerning how we understand television. Finally, the subsequent use of Flying into the Wind and the current use of Gregory's Girl in GCSE examinations, and the place of television in the new National Curriculum orders are briefly considered.
