Distributed Learning System Design: A New Approach and an Agenda for Future Research

This article presents a theoretical framework designed to guide distributed learning design, with the goal of enhancing the effectiveness of distributed learning systems. The authors begin with a review of the extant research on distributed learning design, and themes embedded in this literature are extracted and discussed to identify critical gaps that should be addressed by future work in this area. A conceptual framework that integrates instructional objectives, targeted competencies, instructional design considerations, and technological features is then developed to address the most pressing gaps in current research and practice. The rationale and logic underlying this framework is explicated. The framework is designed to help guide trainers and instructional designers through critical stages of the distributed learning system design process. In addition, it is intended to help researchers identify critical issues that should serve as the focus of future research efforts. Recommendations and future research directions are presented and discussed

A Simulation-Based Teaching Strategy to Achieve Competence in Learners

Background: Simulation-based education has become the mainstay of clinical education in health sciences and medical education. A simulation-based education is a result of work hour restriction placed on graduate learners, increased number of students requiring clinical experience, decreased number of clinical sites and lack of the availability to perform certain procedures by learners. Research has demonstrated that integration of a simulation-based educational teaching strategy in a curriculum and throughout continued learning achieves competence in learners. Methods: The review of the literature highlighted the following topics: (a) history of medical simulation, (b) fidelity used in simulation training, devices and equipment, (c) learning theories associated with simulation-based education, (d) role of simulation training in medical and health sciences education, e) advantages and disadvantages of simulation training, f) competence in simulation-based education, g) debriefing/reflection in simulation. Results: An extensive review of the literature supports the use of a simulation-based teaching strategy in health sciences and medical education. Learning theories associated with simulation-based education allow educators to provide teaching strategies that align with learner’s ability to achieve competence in learning clinical and procedural skills required for their profession. Conclusion: A simulation-based education integrated in all stages of learner education that provides deliberate/repetitive practice and feedback achieves competence in learners throughout a life-time of learning

An intelligent tutoring system for the investigation of high performance skill acquisition

The issue of training high performance skills is of increasing concern. These skills include tasks such as driving a car, playing the piano, and flying an aircraft. Traditionally, the training of high performance skills has been accomplished through the use of expensive, high-fidelity, 3-D simulators, and/or on-the-job training using the actual equipment. Such an approach to training is quite expensive. The design, implementation, and deployment of an intelligent tutoring system developed for the purpose of studying the effectiveness of skill acquisition using lower-cost, lower-physical-fidelity, 2-D simulation. Preliminary experimental results are quite encouraging, indicating that intelligent tutoring systems are a cost-effective means of training high performance skills

A Framework for Delivering Contextually Appropriate Opportunities for Warfighter Practice

Computer-based modeling and simulation has been a training staple in the military domain since the first aircraft simulators were adopted. More recently, virtual environments based on modeling, simulation and serious games, have introduced relatively low-cost, yet high value additions to the learning environment. As these virtual environments have proliferated, many researchers have investigated the relationship between theoretical foundations of learning, learner development and content delivery, and applied their findings in an attempt to bolster learning, yet performance deficiencies continue to exist. This study asserts that performance deficiencies exist in part because of insufficient contextually appropriate opportunities to practice. This work is multi-disciplinary in nature. Its foundation is modeling and simulation engineering; the use of technology to deliver training. Educational psychology and human factors concepts explain the theoretical basis for modeling and simulation as an effective training delivery agent. The study\u27s thesis is that a framework for delivering contextually appropriate opportunities for warfighter practice can be applied to discover whether modeling, simulation and game-based virtual environments have the potential to improve individual performance for learners beyond the Novice Stage (e.g., Competent Stage) of skills acquisition. Furthermore, this conceptually appropriate practice (CAP) framework can be used to assess the potential of low fidelity virtual environments to provide targeted practice and to improve individual performance, not only during training in high-fidelity virtual environments (near transfer) but also in the live environment (far transfer). To evaluate the thesis, this study investigates the relationship of technology and learning science, and features an empirical evaluation of training effectiveness afforded by delivering additional training repetitions using both low-fidelity virtual environment simulator systems and high-fidelity aircraft simulators

he effects of the system of least prompts on teaching comprehension skills during a shared story to students with significant intellectual disabilities

he development of literacy skills is a crucial skill that all students are entitled to develop (Browder, Gibbs, Ahlgrim-Delzell, Courtade, Mraz, Flowers, in press). Currently limited research has been conducted on the acquisition of early literacy skills for students with significant disabilities (Browder, Mims, Spooner, Ahlgrim-Delzell, & Lee, 2008; Browder, Trela, & Jimenez, 2007; Zakas, Browder, & Spooner, 2009) and even more limited on the acquisition of text dependent comprehension (Mims, Browder, Baker, Lee, & Spooner, in press). The current study examined the effects of the system of least prompts to teach multiple types of text dependent listening comprehension question during a shared story to students with significant intellectual disabilities. In addition, maintenance, generalization, and social validity were also examined. A teacher and two paraprofessionals were trained to implement a prompt hierarchy involving three levels (reread, model, physical) during three different shared stories with four different students. Results indicated that all four students increased the number of correctly answered comprehension questions during all three shared stories. In addition, students were able to maintain comprehension after a two week maintenance period. One student was able to generalize the skills used to develop comprehension during a shared story to the third book as well as an additional book. Finally, the interventionists reported high levels of satisfaction with the teaching strategy as well as student outcomes

ENVISIONING BETTER POLICE PERFORMANCE WITH SELECTIVE-FIDELITY TRAINING: LESSONS FROM SIMULATIONS AND VIRTUAL REALITY IN AVIATION AND MEDICINE

This thesis explores how technology-based, selective-fidelity training methods found in aviation and medicine can improve law enforcement training and performance. Professionals in aviation, medicine, and law enforcement all encounter high-risk and unpredictable situations. Within aviation and medicine, research has shown that simulation and virtual reality (VR) can improve performance at all levels—from beginner to advanced. This thesis reviews Bloom’s taxonomy, state- and context-dependent learning, and law enforcement training practices; assesses the efficacy of selective-training methods across the aviation and medical fields; and reviews real-world applications of simulation and VR. This research determined that certain technology-based, selective-fidelity training methods found in aviation and medicine may improve law enforcement training and performance. To best leverage simulation and VR, the law enforcement community should match the device’s fidelity (high or low) to the underlying learning objective; utilize both high- and low-fidelity training methods confidently; and mimic the medical sector’s standard, policy, and procedure development for technology-based, selective-fidelity training methods. Also, high-fidelity training methods may improve performance in novel situations. Finally, law enforcement trainers should use certain devices to mitigate stress, treat post-traumatic stress disorder, teach checklist material, and promote confidence.Civilian, City of Tulsa, Tulsa Police DepartmentApproved for public release.

An Application of High Fidelity FTDs for Ab Initio Pilot Training: The Way Ahead

Decreases in simulation costs and increases in aircraft training costs led to the need for further investigation into the application of simulation-based training. Researchers conducted an eighteen-month study using ab initio student pilots as participants. This study applied a Federal Aviation Administration (FAA) approved, Part 142, flight-training curriculum that included 60% flight training device (FTD) use. Researchers identified five causal factors that warranted further investigation. The causal factors identified were visual fidelity, procedural similarity, dynamic flight environment, difficulty of task, and visual scanning and response. These causal factors have the potential to affect transfer of training (ToT) from simulated flight to aircraft flight. Steps are being taken to optimize training while considering the causal factors. --From the article
