The cost of primary, secondary and higher education consumes large percentages of the incomes of families, states and even countries every year. In this paper, we describe how automation can not only greatly reduce the cost of education, but also create new learning paradigms that can increase the effectiveness of that education as compared to traditional classroom learning. Intelligent Tutoring Massively Open Online Courses (ITMOOCs) can seamlessly deliver entire curricula while ensuring that students achieve and maintain the required level of proficiency in every curriculum topic. This is achieved by organizing the curriculum into an ontology of interconnected topic nodes, and assessing the students' performance after he/she covers every node. The Intelligent Tutoring System (ITS) continuously adapts the course's delivery to the needs of each student by skipping over topics that the student demonstrates proficiency in, and reviewing topics that are determined to be the cause of assessment failures in downstream course nodes. The ITS can also ensure that students maintain the required level of proficiency in the topics they have learned throughout their educational and professional careers by assigning an expiration time to each curriculum node after which it is reassessed. The system allows each student to set unique educational goals by selecting the individual topics that he/she ultimately wants to learn. Copyright © 2013 by ASME. Source

The education sector is about to undergo a revolution in which automation of instruction delivery using Intelligent Tutoring Systems (ITSs) will vastly improve accessibility to learning at a fraction of what that education costs today. This will be achieved while obtaining better student outcomes, and a more individualized learning experience as compared to traditional learning using human teachers in classroom settings. In this paper, we will present a review of the current state of ITSs along with the characteristics of a new more innovative ITS. The potential and consequences of this new learning paradigm will also be explored. © American Society for Engineering Education, 2013. Source

In this paper we present the main features of a virtual-reality enhanced online learning environment that can be used to deliver fully automated online courses with an ultimate goal of substituting traditional classroom instruction for many science, technology, engineering and math courses. The learning environment incorporates a high level of interactivity that will make the student an active participant in the learning experience, rather than a passive spectator. Virtual-reality is seamlessly integrated in order to simulate lab experiments, scientific instruments and/or industrial equipment. This will help bridge the gap between real world experience and online learning. The learning environment is illustrated using recently developed online courses for freshman university Physics, welding, CNC machining, and centrifugal pump maintenance. © 2011 by ASME. Source

A flexible multibody dynamics explicit time-integration parallel solver suitable for real-time virtual-reality applications is presented. The hierarchical "scene-graph" representation of the model used for display and user-interaction with the model is also used in the solver. The multibody system includes rigid bodies, flexible bodies, joints, frictional contact constraints, actuators and prescribed motion constraints. The rigid bodies rotational equations of motion are written in a body-fixed frame with the total rigid body rotation matrix updated each time step using incremental rotations. Flexible bodies are modeled using total-Lagrangian spring, truss, beam and hexahedral finite elements. The motion of the elements is referred to a global inertial Cartesian reference frame. A penalty technique is used to impose joint/contact constraints. An asperity-based friction model is used to model joint/contact friction. A bounding box binary tree contact search algorithm is used to allow fast contact detection between finite elements and other elements as well as general triangular/quadrilateral rigid-body surfaces. The real-time solver is used to model virtual-reality based experiments (including mass-spring systems, pendulums, pulley-rope-mass systems, billiards, air-hockey and a solar system) for a freshman university physics e-learning course.

By fully automating all aspects of the learning experience for online courses, a large reduction of education costs can be achieved, while simultaneously matching or improving student performance as compared to human delivered online or traditional lectures. The main elements of an effective fully automated online course or lab are: fully automated content delivery using text-to-speech technology, highly visual course presentation using animated 2D and 3D illustrations that are synchronized with the course delivery, interactive 2D and 3D activities, and automated student assessments. A two semester undergraduate physics course that uses these elements to deliver a fully automated learning experience will be presented in this paper. The course can significantly decrease the cost of learning, while improving accessibility, quality, and uniformity of instruction. The course has a virtual reality physics lab with physics-based modeling of the relevant underlying principles and a variety of interactive physics experiments. © 2012 American Society for Engineering Education.
