Gaze behavior among experts and trainees during optic disc examination : does how we look affect what we see?

Purpose. The authors compared the visual gaze behaviors of glaucoma subspecialists with those of ophthalmology trainees during optic disc and retinal nerve fiber layer (RNFL) examination.

Methods. Seven glaucoma subspecialists and 23 ophthalmology trainees participated in the project. Participants were shown eight glaucomatous optic disc images with varied morphology. Eye movements during examination of the optic disc photographs were tracked. For each disc image, graders were asked to assign a presumptive diagnosis for probability of glaucoma. There was no time restriction.

Results. Overall, trainees spent more time looking at disc images than glaucoma subspecialists (21.3 [13.9–37.7] vs. 16.6 [12.7–19.7]) seconds; median [interquartile range (IQR)], respectively; P < 0.01) and had no systematic patterns of gaze behavior, and gaze behavior was unaltered by disc morphology or topographic cues of pathology. Experienced viewers demonstrated more systematic and ordered gaze behavior patterns and spent longer times observing areas with the greatest likelihood of pathology (superior and inferior poles of the optic nerve head and adjacent RNFL) compared with the trainees. For discs with focal pathology, the proportion of total time spent examining definite areas of pathology was 28.9% (22.4%–33.6%) for glaucoma subspecialists and 13.5% (12.2%–19.2%) for trainees (median [IQR]; P < 0.05). Furthermore, experts adapted their viewing habits according to disc morphology.

Conclusions. Glaucoma subspecialists adopt systematic gaze behavior when examining the optic nerve and RNFL, whereas trainees do not. It remains to be elucidated whether incorporating systematic viewing behavior of the optic disc and RNFL into teaching programs for trainees may expedite their acquisition of accurate and efficient glaucoma diagnosis skills.

Augmented optometry training simulator with multi-point haptics

Training of optometrists is traditionally achieved under close supervision of peers and superiors. With the rapid advancement in technology, medical procedures are performed more efficiently and effectively, resulting in faster recovery times and less trauma to the patient. However, application of this technology has made it difficult to effectively demonstrate and teach these manual skills as the education is now a combination of not only the medical procedure but also the use of the technology. In this paper we propose to increase the training capabilities of optometry students through haptically-enabled single-point and multi-point training tools as well as augmented reality techniques. Haptics technology allows a human to touch and feel virtual computer models as though they are real. Through physical connection to the operator, haptic devices are considered to be personal robots that are capable of improving the human-computer interaction with a virtual environment. These devices have played an increasing role in developing expertise, reducing instances of medical error and reducing training costs. A haptically-enabled virtual training environment, integrated with an optometry slit lamp instrument can be used to teach cognitive and manual skills while the system tracks the performance of each individual. These interactions would ideally replicate every aspect of the real procedure, consequently preparing the trainee for every possible scenario, without risking the health of a real patient.

Enhancing audio-haptic enabled novel dental training platform performance

Existing haptic and non-haptic dental simulators do not eliminate the problem of hand instability while using the haptic devices for training purpose. This paper reports an audio-haptic dental training platform, which uses a Hand Stability System to reduce the effect of nervousness and hand instability for trainee dental students. Maintaining the ease of implementation, application customizability and the cost factor, the proposed platform increases the training efficiency by enhancing the immersive haptic experience with hand stability. This haptic platform includes multiple angle viewing techniques, audio feedback and session recording for after action review. Trials using this preliminary platform reduced the effect of human nervousness and hand instability due to the customized design.

The association between investigative interviewers' knowledge of question type and adherence to best-practice interviewing

It is well established that not all investigative interviewers adhere to ‘best-practice’ interview guidelines (i.e., the use of open-ended questions) when interviewing child witnesses about abuse. However, little research has examined the sub skills associated with open question usage. In this article, we examined the association between investigative interviewers' ability to identify various types of questions and adherence to open-ended questions in a standardized mock interview. Study 1, incorporating 27 trainee police interviewers, revealed positive associations between open-ended question usage and two tasks; a recognition task where trainees used a structured protocol to guide their response and a recall task where they generated examples of open-ended questions from memory. In Study 2, incorporating a more heterogeneous sample of 40 professionals and a different training format and range of tests, positive relationships between interviewers' identification of questions and adherence to best-practice interviewing was consistently revealed. A measure of interviewer knowledge about what constitutes best-practice investigative (as opposed to knowledge of question types) showed no association with interviewer performance. The implications of these findings for interviewer training programs are discussed.

Common variants of the resistance mechanism in the Smith Machine: analysis of mechanical loading characteristics and application to strength-oriented and hypertrophy-oriented training

The Smith machine is a pervasive weight-training apparatus, used extensively by a wide population of weight trainers, from novices to high-level athletes. The advantages of using a Smith machine over free-weight resistance are disputed, with conflicting findings reported in the literature. In this study, we are interested in practical differences between 3 types of loading mechanisms found in modern Smith machines. In addition to the basic design comprising a constrained weighted barbell, alterations with a counterweight and a viscous resistance component are examined. The approach taken is that of employing a recently proposed representation of force characteristics that may be exhibited by a trainee and a predictive model of thus effected adaptation. A computer simulation is used to predict the effects of the 3 linear Smith machine designs in the framework of different exercise protocols. Our results demonstrate that each resistance component, vertically constrained load, counterweight, and viscous, can be matched with a particular training context, in which it should be preferred. Thus, a number of practical guidelines for weight-training practitioners are recommended. In summary, (a) at low intensities (55–75% of 1 repetition maximum [1RM]) used in strength-endurance training, a viscous resistance containing the Smith machine was found to offer advantages over both a constrained load only and counterweighted designs; (b) at medium intensities (75–85% of 1RM) typically employed in hypertrophy-specific training, the counterweighted Smith machine design was found to offer the best choice in terms of high-force development and total external work performed; finally, (c) at high training intensity (90–100% of 1RM), the optimal prescription was found to be more dependent on the specific athlete’s weaknesses, highlighting the need for continual monitoring of the athlete’s force production capabilities. To ensure that appropriate adjustments are made to the athlete’s training regimen, the practitioner should consider the full set of findings of this article and the accompanying discussion.

Errors in the identification of question types in investigative interviews of children

This study examined the incidence and nature of the errors made by trainee coders during their coding of question types in interviews in which children disclosed abuse. Three groups of trainees (online, postgraduate and police) studied the coding manual before practising their question coding. After this practice, participants were given two-page field transcripts to code in which children disclosed abuse. Their coding was assessed for accuracy; any errors were analysed thematically. The overall error rate was low, and police participants made the fewest errors. Analysis of the errors revealed four common misunderstandings: (1) the use of a ‘wh’ question always denotes a specific cued-recall question; (2) ‘Tell me’ always constitutes an open-ended question; (3) open-ended questions cannot include specific detail; and (4) specific questions cannot elicit elaborate responses. An analysis of coding accuracy in the one group who were able to practise question coding over time revealed that practice was essential for trainees to maintain their accuracy. Those who did not practise decreased in coding accuracy. This research shows that trainees need more than a coding manual; they must demonstrate their understanding of question codes through practice training tasks. Misunderstandings about questions need to be elicited and corrected so that accurate codes are used in future tasks.

The influence of organisational commitment, job involvement and utility perceptions on trainees’ motivation to improve work through learning

Workplace training is a key strategy often used by organisations to optimise performance. Further, trainee motivation is a key determinant of the degree to which the material learned in a training programme will be transferred to the workplace, enhancing the performance of the trainee. This study investigates the relationship between several components of the Revised Human Resource Development (HRD) Evaluation and Research Model. This model provides a framework for diagnosing and understanding the causal influences of HRD intervention outcomes on training effectiveness. Data were obtained from an online questionnaire completed by 105 employees of various organisations. Findings revealed that affective organisational commitment, job involvement and utility perceptions are predictors of motivation to learn and transfer learning. An interaction effect was found, with increased affective organisational commitment predicting greater motivation to learn when training was of lower perceived utility. These findings suggest that the design and delivery of training should emphasise the relevance and utility of the programme in order to encourage greater trainee motivation and maximise return on investment. Additionally, implementing strategies aimed at promoting organisational commitment would appear beneficial.

Facilitating the highly bonded cohort : should more be done to anticipate and reduce the potential for hyper-cohesiveness and deindividuation in therapy training cohorts in universities?

Successfully facilitating learning for small therapy training programmes requires a special understanding of the psychological work of group processes. Students in therapy training spend almost every class together over two or more years. In these student groups, or cohorts, individuals manage themselves within a unique interpersonal and intragroup dynamic. Course instructors must develop their capacity to work effectively with this specific learning milieu. At the same time, the particular dynamics of the cohort context might not be understood by university management where increasingly few cohort contexts exist for students. Consequently, phenomena arising from the specialised nature of the group environment may not be well understood outside of the expertise of the course. In the first part of the paper, the international literature about learning in cohorts is reviewed. In the second part, this reflection is further developed to explore facilitation of a group that has some features of what might be described as negative cohesiveness, or what is described in family theory as enmeshment. Some consideration as to how to anticipate and off-set potential difficulties for groups in therapy training courses is also contributed.

The limitations of front-end loading in undergraduate university programs

This paper shows how Mead’s theory of emergence can prove explanatory in how the theory-practice gap is co-created and sustained in front-end loading university programs. Taking teacher education as an exemplar, we argue that the trainee teacher encounters different and oft-times conflicting environmental, social and cultural conditions in the two “fields of interaction” of the training program, namely, on-campus work and in-school experience. The argument draws on interview and focus group data collected via a study of first-year graduate teachers of an Australian teacher education program. We conclude that role taking and self-regulated behaviour within the two environmental fields of interaction in front-end loading programs inhibit the trainee professional from exercising the power of agency to implement theory learned at university in practice in the workplace. Further, we propose that Mead’s theory of emergence proves effective in explaining a major limitation of front-end-loaded university programs.

Using Mead's Theory of Emergence as a framework for sociological inquiry into pre-service teacher education

In this paper we take up Chang's (2004) challenge to apply Mead's theory of emergence in sociological inquiry. Largely overlooked by scholars, this theory is shown to prove explanatory in one field where limited solutions have been found to date. Specifically, the theory sheds light on how the theory-practice gap is created and sustained in pre-service teacher education. The argument is that under current institutional arrangements the trainee/beginning teacher encounters different and oft-times conflicting environmental, social and cultural conditions in the two 'fields of interaction' (Mead, 1934: 249) of their training program, namely, the on-campus pre-service program and the school. The argument draws on interview and focus group data collected via a study of first-year graduate teachers of an Australian pre-service teacher education program. We conclude that the Meadian mechanisms of role taking and self-regulated behaviour within the two environmental fields of interaction inhibit the trainee/beginning teacher from exercising the power of agency to implement theory learned at university in practice in the classroom. In this sense Mead's theory of emergence predicts the obduracy of the gap between theory and practice in teacher education.

A Meadian analysis of pre-service and beginning teacher practice

This paper uses Mead’s theory of emergence to examine the theory-practice gap in pre-service teacher education. The paper argues that the theory-practice gap in pre-service teacher education under present institutional arrangements is axiomatic in the process of emergence from pre-service to graduate teachers. The argument draws on interview and focus group data collected via a study of first-year graduate teachers of an Australian pre-service teacher education programme. An interpretation of the data using Mead’s theory of emergence demonstrates that role taking and self-regulated behaviour inhibit the trainee teacher from exercising the power of agency to implement theory learned at university into practice in the classroom. Thus, Mead’s theory of emergence explains the obduracy of the gap between theory and practice in teacher education.

The "theory-practice gap": Turning theory into practice in a pre-service teacher education program

his thesis investigates the theory-practice gap using the exemplar of teacher education. The research is situated in a pre-service teacher education program that explicitly seeks to bridge the theory-practice gap so that it produces “learning managers” who can negotiate the contemporary knowledge society in ways different to those of their predecessors. The empirical work reported in this thesis describes and interprets the experiences of preservice and beginning teachers in turning theory into practice. In order to accomplish this outcome, the thesis draws on Mead’s theory of emergence and symbolic interactionism to provide a theoretical perspective for meaning-making in social situations. Data for the study were collected through interviews and focus groups involving a sample of first-year graduate teachers of an Australian pre-service teacher education program. The main finding of this thesis is that the theory-practice gap in pre-service teacher education under present institutional arrangements is an inevitable phenomenon arising as individuals undergo the process of emergence from pre-service to graduate and then beginning teachers. The study shows that despite the efforts of the program developers, environmental, social and cultural conditions in teacher education processes and structures and in schools inhibit the trainee and novitiate teacher from exercising agency to effect change in traditional classroom practices. Thus, the gap between theory and practice is co-produced and sustained in the model that characterises contemporary preservice teacher education in the perspectives of lecturers, teachers and administrators.

Learning theory for VET teachers

 Teaching in the VET sector is a complex and highly rewarding vocation. This book provides the reader with an in depth exploration of both the theory and the practice of teaching in this sector. Each chapter invites the reader to reflect on their own practice and offers practical examples and case stories to assist the teacher to develop their own professional expertise. The chapters have been written by highly acknowledged VET researchers and teachers and all the chapters have been reviewed by people with high levels of respect and credibility in the field.

This book provides the new teacher or trainee teacher with an overview of the VET sector in Australia and introduces the reader to some of the issues that are part of our VET environment. The book explores some of the dimensions of teaching and the diverse range of learners that are characteristic of any VET classroom, workshop or enterprise setting where teaching is taking place. The book also introduces the reader to some of the major learning theories that are relevant in VET and provides practical guidance on the implications of theory for VET practice.

High quality assessment is critical to the credibility of VET and the book includes a chapter where this controversial area is made accessible to the reader. Language Literacy and Numeracy are now an embedded feature of VET teaching and the chapter on this topic discusses different views of LLN and encourages the reader to interrogate their own skills and apply their learning to the their teaching. eLearning is increasingly part of VET teaching and this is discussed in detail. Similarly engaging with industry is fast becoming a significant part of the role of the VET teacher and the rationale and the practical and day to day implications for this development are explored.The act of teaching is investigated and this chapter brings together many of the themes raised elsewhere. Finally the reader is introduced to the benefits of reflective practice through an exploration of some of the ways that teachers can evaluate the effectiveness of their own teaching.

This book is a must for new teachers and a refreshing read for those already engaged in the field

Knowledge-based automatic performance evaluation for medical training debriefing

 Manikin-based medical simulation has been shown to benefit the knowledge, skills and attitudes of the learner, and to impart favourable patient effects. A vital component of any training simulation is the after-session discussion with trainees to debrief their performance. In this study we develop a rule-based debriefing tool for improving the efficacy of medical training sessions. Unlike most existing de-briefing tools, the tool presented here has been designed to reduce medical trainer assessment time and to improve evaluation accuracy through a largely automated evaluation of trainee performance. The developed tool is acknowledged by the School of Medicine of Deakin University as an important advancement in assisting medical trainers carry out the debriefing process effectively and efficiently.
