Error-Visualization by Error-Based Simulation and Its Management
Tsukasa Hirashima · 1998
: Behavior simulation is an effective method to visualize the meaning of mechanical concepts and has been applied in many computer-aided education systems to visualize the mechanical concepts. These simulations aren't useful, however, for a learner who has already formulated an erroneous equation. In order to help the learner to recognize and correct the error, simulating the erroneous equation is a promising method. In this paper, we propose Error-Based Simulation(EBS) which reflects an erroneous equation a learner made in solving a mechanical problem. We have developed a prototype system which generates EBS by changing the value of "velocity" or "acceleration" of an object by using an erroneous equation. In EBS, the object behaves in a strange manner. The differences between EBS and normal simulation illustrate the error clearly. EBS, however, isn't always effective for a learner to recognize and correct an error. The effect depends on how strange it behaves. Therefore, diagnosing be...
