Abstract. The progressive nature of the simulation industry requires advanced training techniques, the strategic core
of which is the management of learning. A systematic approach to learning is further reliant on the development and
implementation of effective evaluation strategies. Leaders in the field have identified the need for the re-development
of evaluation methods including outcome measures, system assessment, and the widespread acceptance and
incorporation of evaluation techniques. The current need for training evaluation extends beyond the well established
validation of simulators as training tools. Effective evaluation structures increase the effective use of training systems
and the application of skills acquired during the training program, further enabling the scientific validation of all facets
of the training process. The development of effective training evaluation processes grounded in psychometrics and
cognitive science is essential for the continuation of advanced training within the simulation community. This paper
presents an external evaluation of an industry developed evaluation process of a reality training centre utilising
immersive simulation within the rail transport industry. The evaluation related to a recent round of a safety
management system training program delivered across all levels of the rail workforce within an Australian State Rail
Corporation. The measure was not found to provide an accurate assessment of identified program objectives.
However, valuable insights into workforce perceptions of the training process, programs, and facilities were
established. Discussion highlights the identification and evaluation of the learning components of the training task, the
effective and efficient use of the training facility, the enhancement of the training process, and the re-development of
an effective training evaluation system. Evaluation essentially represents the ability to understand the multifaceted
training process and the learning outcomes produced, allowing application of this knowledge for further advancement
of simulation use and effective training techniques.

  • 1. Towards Managing the Learning Process: Evaluation of Simulation Training Rebecca J. Atkins1; Malcolm R. Smith1; Anthony R. Mildred2; & H. Peter Pfister1 1 School of Behavioural Sciences, The University of Newcastle 2 NSW RailCorp Rebecca.Atkins@newcastle.edu.au Abstract. The progressive nature of the simulation industry requires advanced training techniques, the strategic core of which is the management of learning. A systematic approach to learning is further reliant on the development and implementation of effective evaluation strategies. Leaders in the field have identified the need for the re-development of evaluation methods including outcome measures, system assessment, and the widespread acceptance and incorporation of evaluation techniques. The current need for training evaluation extends beyond the well established validation of simulators as training tools. Effective evaluation structures increase the effective use of training systems and the application of skills acquired during the training program, further enabling the scientific validation of all facets of the training process. The development of effective training evaluation processes grounded in psychometrics and cognitive science is essential for the continuation of advanced training within the simulation community. This paper presents an external evaluation of an industry developed evaluation process of a reality training centre utilising immersive simulation within the rail transport industry. The evaluation related to a recent round of a safety management system training program delivered across all levels of the rail workforce within an Australian State Rail Corporation. The measure was not found to provide an accurate assessment of identified program objectives. However, valuable insights into workforce perceptions of the training process, programs, and facilities were established. Discussion highlights the identification and evaluation of the learning components of the training task, the effective and efficient use of the training facility, the enhancement of the training process, and the re-development of an effective training evaluation system. Evaluation essentially represents the ability to understand the multifaceted training process and the learning outcomes produced, allowing application of this knowledge for further advancement of simulation use and effective training techniques. within the field of simulation training and the limited 1. INTRODUCTION acceptance and incorporation of evaluation techniques The progressive nature of the simulation industry is requires persistent intervention [6],[8]. The need for the reliant upon advanced training techniques centring on re-development of evaluation strategies has been the cognitive concepts of human learning. identified by industry personnel, highlighted as a means Internationally, the emerging role of the behavioural of continued advancement [6]. This need extends sciences and the increasing presence of Human Factors beyond assessment of technology and the well (HF) within the cross-disciplinary industry of simulation established validation of simulators as training tools [9], are reenergising the pursuit of advancement through a [10] to psychometrics and cognitive science with the focus on human and system performance [1],[2],[3]. The ongoing evaluation of all facets of the training process strategic core of this approach is the management of with particular emphasis on the role of learning learning. Research has identified the progressive need [11],[12],[13]. Evaluation is an essential adjunct to within the simulation industry to extend training simulation training aimed at optimising the effective use practices beyond the current technological focus to of technology and maximising performance outcomes. intensify the learning aspect of training [4],[5].

Early theories of training physiological and behavioural limits of human operators present evaluation as an essential and final phase of the maximising efficiency and effectiveness and improving training process that serves as the measure from which safety [3]. learning is examined and training effectiveness derived [12]. Kirkpatrick’s [12] model of training evaluation remains dominant within industrial/organisational psychology [8],[15]. The model presents four levels of training evaluation, each increasing in depth. The four levels (presented in Figure 1) are: (1) how trainees feel about the program, (2) quantity of learning in the form of increased knowledge and understanding, (3) changes in behaviour, and (4) effects of behavioural change on the attainment of learning objectives. These can be Figure 2: The ‘training cycle’ model [11]. further simplified as: (1) reactions and feelings, (2) learning, (3) behaviour, and (4) results. The higher levels of evaluation refer to changes in learning and 1.2 Training and Evaluation in Rail Transportation behaviour where learning is represented by the Human error is well documented as the leading acquisition of skills and knowledge and adoption of new contributor to in excess of 80% of all transportation behaviours [16]. The attainment of desired learning accidents [1],[5],[19]. HF investigations into complex outcomes is vital to the effectiveness of training modern transport systems have revealed the ability for [8],[11],[13],[17]. The Kirkpatrick model highlights the dramatic reduction of error rates through effective fundamental aim of training programs to achieve change training [1],[19]. Research has further shown effective and/or development in the cognitive knowledge, skills, training to be a cost-effective method for the reduction and/or attitudes of trainees indicating the achievement of HF related transportation accidents [4]. Accurate of learning outcomes [18]. Essentially training statements as to training effectiveness within the effectiveness is determined by measuring how well Australian rail industry cannot be made to date, as no programs meet learning outcomes set for training and publicly available/published scientific evaluation has ultimately the level of behavioural transfer into the taken place. Without an effective evaluation process workplace [11],[13],[18]. there is no evidence to suggest the presented concepts or learning objectives of a training program will be transferred into behaviour [11]. This is cause for concern particularly when training is used as an organisational strategy for the reduction of human error as a causal factor of accidents, as is the case with immersive simulation (IS) training within the Australian rail transport industry. The unquestionable importance of evaluation was stressed in the inquiry into the Glenbrook rail disaster. Employees who participated in safety training (which has not been evaluated) failed to exhibit key cognitive reasoning skills resulting in failure Figure 1: Four level model of evaluation [12]. to take appropriate action to avert the collision. The inquiry findings suggest effective evaluation of the A best practice model of training has been proposed by training program may have averted the disaster [20]. Bramley [11] extending the Kirkpatrick model and Developing effective measurement tools to evaluate rail emphasising the integral role of evaluation in the wider safety training is paramount and is a strong contributor training process. According to the ‘training cycle’ model to the rationale of the current study.

However, for Factors 3 and 4 participant perceptions, opinions, and views toward comparative CAs could not be calculated as only one previous and current IS training. Within the SMS 2.4 item loaded on each, while the single item loadings on EQ design, response scales for these Factors differed. Factor 3 (alpha = .86) and Factor 4 (alpha = .88) were To allow for statistical comparison, item responses were strong. Construction of the questionnaire made it recoded into a two-point scale of either a positive or difficult to compare items. Several questions require the negative response. Results indicate a positivity rating of choice of one of three options that are unique 75% towards previous IS scenarios (Factor 2) and 85% categorical responses to the particular question, toward SMS 2.4 (current) scenarios (Factor 3). resulting in a lack of comparative power.

Further PCA examination revealed many scenarios are improving from previous rounds of questions loaded on more than one Factor indicating training.
