Central Government Agencies and the Management of Vocational Educational and Training

The article considers current proposals for the contribution of central government departments towards the effective management of vocational education and training in The United Kingdom. Starting from some broad assumptions about the objectives of vocational education and training, an attempt is made to place discussions about what roles the Department of Education and Science and the Department of Employment/Manpower Services Commission should play in this field within the context of events that have occurred over the past forty years. Three alternative forms of management relationships are considered, two of which recommend the formation of a new department, either a Department of Education and Training or a Department of Employment and Vocational Training, while the third supports a refinement of present ad hoc inter‐departmental arrangements. After examining the perceived advantages and disadvantages of these proposals, it is suggested that a new central government management system is required in order to provide a more systematic response. The article concludes with the suggestions that such a system might have consequences for institutional change, individual freedom of choice and the improvement of opportunities for disadvantaged groups different from those that are usually predicted.     

Successful and unsuccessful problem solving in classical genetic pedigrees

Using the think-aloud interview technique, 16 undergraduates and 11 genetics graduate students and biology faculty members were asked to solve from 1 to 3 classical genetics problems which require pedigree analysis. Subjects were classified as either successful or unsuccessful and the performances of these groups were analyzed from videotaped recordings of the interviews. A number of previously reported findings were corroborated. Additional observations are discussed in terms of genetic knowledge, use of production rules, strategy selection, use of critical cues, hypothesis testing, use of logic, understanding of issues of probability, and the thinking process itself. Taken collectively, these findings evidence a remarkable similarity between the successful solution of pedigree problems and the processes of medical diagnosis and scientific investigation. This convergence of research findings suggests a qualitative advance in the understanding of problem solving. Based on this understanding, recommendations for classroom instruction are presented.     

Benefits of naturalistic methods in research in science education

The author argues that naturalistic (e.g., qualitative, ethnographic) research is appropriate for studying science education. Field methods such as indepth interviewing and observation are used, and the logic of the inquiry is inductive rather than hypothetico-deductive. The stages of naturalistic research are explained and illustrated with material from the NSF-sponsored Case Studies in Science Education. Problems in traditional research methods (construct validity, ecological generalization) are presented as justification for inductive models or models based on multiple methods, perspectives, and operations.     

The medical librarian and computer-assisted instruction

The requirements for a computer-assisted instruction (CAI) system in terms of hardware, communications, software, and personnel are discussed, and unique characteristics of CAI are reviewed. Current CAI applications in the medical field include programs in undergraduate medical and dental education, training of nurses and physical therapists, units for interns and residents, and continuing education for physicians. Certain problems exist in the current state of the art, however, including unsatisfactory aspects of each of the system components. The potential role of the medical librarian as a member of a CAI personnel team is explored, and contributions he can make in program development, monitoring, and evaluation are suggested. Medical librarians may themselves have opportunities in the future to use CAI to develop library skills and special subject knowledge. It is proposed that introduction of CAI may have the additional benefit of encouraging increased use of on-line bibliographic retrieval systems.     

The effect of low back pain on trunk muscle size/function and hip strength in elite football (soccer) players

ABSTRACT

Low back pain (LBP) is a common problem in football (soccer) players. The effect of LBP on the trunk and hip muscles in this group is unknown. The relationship between LBP and trunk muscle size and function in football players across the preseason was examined. A secondary aim was to assess hip muscle strength. Twenty-five elite soccer players participated in the study, with assessments conducted on 23 players at both the start and end of the preseason. LBP was assessed with questionnaires and ultrasound imaging was used to assess size and function of trunk muscles at the start and end of preseason. Dynamometry was used to assess hip muscle strength at the start of the preseason. At the start of the preseason, 28% of players reported the presence of LBP and this was associated with reduced size of the multifidus, increased contraction of the transversus abdominis and multifidus muscles. LBP decreased across the preseason, and size of the multifidus muscle improved over the preseason. Ability to contract the abdominal and multifidus muscles did not alter across the preseason. Asymmetry in hip adductor and abductor muscle strength was found between players with and without LBP. Identifying modifiable factors in players with LBP may allow development of more targeted preseason rehabilitation programmes.     

Effects of increasing and decreasing physiological arousal on anticipation timing performance during competition and practice

The aim of this study was to investigate if the effects of changes in physiological arousal on timing performance can be accurately predicted by the catastrophe model. Eighteen young adults (8 males, 10 females) volunteered to participate in the study following ethical approval. After familiarisation, coincidence anticipation was measured using the Bassin Anticipation Timer under four incremental exercise conditions: Increasing exercise intensity and low cognitive anxiety, increasing exercise intensity and high cognitive anxiety, decreasing exercise intensity and low cognitive anxiety and decreasing exercise intensity and high cognitive anxiety. Incremental exercise was performed on a treadmill at intensities of 30%, 50%, 70% and 90% heart rate reserve (HRR) respectively. Ratings of cognitive anxiety were taken at each intensity using the Mental Readiness Form 3 (MRF3) followed by performance of coincidence anticipation trials at speeds of 3 and 8 mph. Results indicated significant condition × intensity interactions for absolute error (AE; p = .0001) and MRF cognitive anxiety intensity scores (p = .05). Post hoc analysis indicated that there were no statistically significant differences in AE across exercise intensities in low–cognitive anxiety conditions. In high–cognitive anxiety conditions, timing performance AE was significantly poorer and cognitive anxiety higher at 90% HRR, compared to the other exercise intensities. There was no difference in timing responses at 90% HRR during competitive trials, irrespective of whether exercise intensity was increasing or decreasing. This study suggests that anticipation timing performance is negatively affected when physiological arousal and cognitive anxiety are high.     

Three-dimensional analysis of a lofted instep kick by male and female footballers

There is a paucity of data describing the lofted instep kick and little information on the kinematic differences between male and female footballers. This study provides a preliminary investigation into the differences in motion patterns between the sexes. A four-camera motion analysis system videoed 13 amateur footballers (7 female and 6 male) attempting a standardised task that represented a lofted instep kick of approximately 35 m. Footballers performed 20 kicks, with the three trials categorised closest to the standardised distance retained for statistical analysis. Three-dimensional motion patterns for kicks of 35 m illustrated that female footballers produced greater fluctuation in movement patterns for pelvic, hip joint and thoracolumbar spine motion in the frontal plane; thorax and hip joint transverse rotation; and ankle dorsiflexion/plantarflexion motion. Peak hip extension (P = 0.018), impact hip abduction (P = 0.032), impact ankle plantar flexion (P = 0.030) and resultant ball velocity (P = 0.004) differed significantly between sexes. Principle component analysis highlighted associations between kinematic variables related to ball velocity and sex including a reduced hip abduction and increased internal rotation approaching impact, and greater peak knee flexion, respectively. In summary, increased variation in direction of segment motion, increased backswing and formation of a tension arc by females compared to males, may be related to anthropometric, strength and muscle activation differences. Specifically, this exploratory study indicates future research would benefit from exploring trunk, pelvis and hip kinematics and kinetics, and whether training the trunk, pelvis and hip musculature assists female footballers.     

The Influence of Instructor-Student Rapport on Instructors’ Professional and Organizational Outcomes

Students and teachers have relational goals and needs, yet little research has examined the relational goals of instructors and how achieving those goals may affect instructor outcomes. This study examined instructors’ perspectives on instructor-student rapport. Results revealed that instructors who build rapport with students are likely to experience teaching satisfaction, affective commitment to the institution, and enhanced teaching efficacy. However, instructor-student rapport was not related to instructor morale. The findings in this study highlight the importance of positive instructor-student relationships in the classroom and the implications for both instructors and administrators.
