Researching primary engineering education: UK perspectives,an exploratory study

This paper draws attention to the findings of an exploratory study that critically identified and analysed relevant perceptions of elementary level engineering education within the UK. Utilising an approach based upon grounded theory methodology, 30 participants including teachers, representatives of government bodies and non-profit providers of primary level engineering initiatives were interviewed. Three main concepts were identified during the analysis of findings, each relevant to primary engineering education. These were pedagogic issues, exposure to engineering within the curriculum and children's interest. The paper concludes that the opportunity to make a real difference to children's education by stimulating their engineering imagination suggests this subject area is of particular value.     

Facial feature tracking: a psychophysiological measure to assess exercise intensity?

The primary aim of this study was to determine whether facial feature tracking reliably measures changes in facial movement across varying exercise intensities. Fifteen cyclists completed three, incremental intensity, cycling trials to exhaustion while their faces were recorded with video cameras. Facial feature tracking was found to be a moderately reliable measure of facial movement during incremental intensity cycling (intra-class correlation coefficient = 0.65–0.68). Facial movement (whole face (WF), upper face (UF), lower face (LF) and head movement (HM)) increased with exercise intensity, from lactate threshold one (LT1) until attainment of maximal aerobic power (MAP) (WF 3464 ± 3364mm, P < 0.005; UF 1961 ± 1779mm, P = 0.002; LF 1608 ± 1404mm, P = 0.002; HM 849 ± 642mm, P < 0.001). UF movement was greater than LF movement at all exercise intensities (UF minus LF at: LT1, 1048 ± 383mm; LT2, 1208 ± 611mm; MAP, 1401 ± 712mm; P < 0.001). Significant medium to large non-linear relationships were found between facial movement and power output (r² = 0.24–0.31), HR (r² = 0.26–0.33), [La^?] (r² = 0.33–0.44) and RPE (r² = 0.38–0.45). The findings demonstrate the potential utility of facial feature tracking as a non-invasive, psychophysiological measure to potentially assess exercise intensity.     

A comparison of the capacity of ice hockey goaltender masks for the protection from puck impacts

Goaltenders in ice hockey are the only players that are on the ice for the entire game. Their position exposes them to impacts from collisions with other players, falls to the ice, and puck impacts. In competitive ice hockey leagues, head injuries resulting from puck impacts have been reported with some cases resulting in ending the player’s career. Considerable research has been conducted to assess the performance of hockey helmets; however, few have assessed the performance of goaltenders’ masks. The purpose of this study was to compare the capacity of four goaltenders’ masks for the protection from puck impact as measured by head acceleration and peak force. A Hybrid III headform was fitted with four different goaltender masks and impacted with a hockey puck in three locations at 25 m/s. The masks were found to vary in the level of protection they offered as the mask with the thickest liner resulted in lower forces than the thinnest mask for side impacts; however, the thinnest mask resulted in the lowest force for front impacts. Despite performance differences at specific locations, no one mask proved to be superior as peak acceleration and peak force values did not exceed the thresholds necessary for concussion.     

A Self‐Management Strategy for Increasing Implementation of Behavioural Procedures by Residential Staff

Two preliminary studies explored the use of a self‐management strategy as a component of a training program for residential Child and Family Workers. The self‐management strategy comprised the Correspondence Training procedures of Risley (1977) and the formulation of specific implementation plans (Sanders & Glynn, 1981). Experiment 1 found that prompting staff to formulate plans of how they would implement target behaviour management skills and providing individual feedback on their performance in accordance with their plans resulted in gains in implementation of target skills; no gains in implementation resulted from Instruction and Group Feedback conditions alone. This experiment examined pooled data from 18 staff collected by regular time sampled observations. Experiment 2 introduced similar procedures in a multiple baseline design to four volunteer staff, each of whom selected two target behavioural skills from the training manual. The self‐management strategy resulted in clear gains in implementation of these self‐selected target skills by all four staff. Results are discussed in terms of the potential of the correspondence training paradigm and the formulation of specific implementation plans as an approach to on‐the‐job training of residential staff.     

Letters

Conclusions One of the things particularly disturbing about managing our doctoral programs is the growing realization that our professionals must be more highly trained than those working in the traditional social or physical sciences. It takes longer (and I suspect it is more difficult) to produce the hybrid professional capable of and committed to contributing to educational practice. Our students must be as knowledgeable as the doctoral candidate in (for example) psychology and in addition must acquire a set of skills that deal with enhancing practice in a great variety of settings. It also is disturbing to realize that our doctoral students probably won’t acquire this capability unless faculty members begin to model the skills and approaches they expect their students to acquire. I have consciously ignored a number of areas (curriculum, focus for courses and assessment, and delineation of desirable competencies and performances). At the moment my concern is to communicate my strong belief that we must grow away from the training of people primarily concerned with technical skills in developing instruction, evaluating programs, managing resource centers, and producing films and television programs and focus on the training of people skilled in inquiring about problems and their solutions. Presumably these people would be able to arrive at some solutions that would be useful regardless of their career choices—research, development, production, and/or administration. All student activities involving the actual development of instruction should be conducted in an atmosphere of constant inquiry and critical discussion of the usefulness of the concepts being acquired and the process being employed.     

Infants parse dynamic action

As observers of human behavior, infants are faced with a complex flow of motion in which pauses are rare and only occasionally coincide with boundaries between intentional actions. Two studies investigated whether, despite such complexity, 10- to 11-month-old infants (N = 16 for each study) possess skills for parsing ongoing behavior along boundaries correlated with the initiation and completion of intentions. After being familiarized with digitized sequences of continuous everyday action, infants showed renewed interest in test versions in which motion paused in the midst of an actor's pursuit of intentions (interrupting test videos). In contrast, pauses that suspended motion at intention boundary points (completing test videos) sparked no such renewed interest on infants' part. Moreover, basic salience differences between the two types of test videos were not the source of infants' increased interest when intentions were interrupted (Study 2). These findings demonstrate that infants readily detect disruptions of the structure inherent in intentional action, and hence parse ongoing behavior with respect to such structure. Such parsing skill is likely a prerequisite to the development of genuine intentional understanding.     

The American mixture of higher education in perspective: four dimensions

Several nations are currently considering privatization of parts of their higher education systems. This paper, mainly based on the American experience, examines privatizing public institutions as an alternative to establishing solely private institutions.Institutions are analyzed along four dimensions: (1) ownership (public or private); (2) control (external or internal); (3) financing (public or private funds); and (4) mechanisms for public financing (who controls fund distribution and how). There are varying mixtures along these four dimensions both within countries and around the world, with the American system exhibiting the widest range of combinations. Six categories are described, including four common in the U.S.: I. Independent private, where institutions are independent in ownership, in control, and in basic financing; II. Dependent private, independent in ownership and financing but dependent in control; III. Independent public, dependent in ownership but independent in control and substantially independent in financing; IV. Semi-independent public (state/guild type), dependent in ownership, mixed in control, and heavily dependent in financing (less common in the U.S., but typical of Italy and Latin America); V. Semi-independent public (state/trustee/guild type), where control is shared among state, academic guilds and lay boards of trustees but with mainly state-controlled financing; and VI. Dependent public, the model in the Communist nations.Kerr traces the historical path that led to the mixed American system and examines some of its positive consequences, which include institutional autonomy, diversity, and flexibility. Negative results include possible over-responsiveness to short-term pressures, as from the labor market or student preferences for courses of study, and from supporting business or industry.The author concludes that the American experience with privatized public institutions may serve as a model for those elsewhere who now seek greater institutional differentiation, autonomy, and flexibility within national systems of higher education.     

Test-Taking Strategy as a Mediator between Race and Academic Performance

The issue of race differences in standardized test scores and academic achievement continues to be a vexing one for behavioral scientists and society at large. Ellis and Ryan (2003) suggested that a portion of the cognitive-ability test performance differences between White/Caucasian-American and Black/African-American college students could be attributed to the greater use of ineffective test-taking strategies by the latter group. We replicated and extended their findings by using three outcomes—exam scores in a single academic course, self-reported GPA, and a measure of verbal abilities. Ellis and Ryan reported that the variance in cognitive-ability test performance explained by race dropped by 48% (i.e., from 21% originally to 11%) when controlling for the mediator, ineffective test-taking strategies. Our results were less dramatic, but also indicated that ineffective test-taking strategies accounted for 19% to 25% of the variance originally explained by race. In addition, reminiscent of the disidentification effect, supplementary analyses showed that academic/intellectual self-perceptions correlated with the criterion measures but only for White participants. These results suggest that a portion of the race difference on test scores might be accounted for by test-taking strategies.
