A Method for Supporting English Composition by Animations as a Trigger for Reflection

摘要

We present a method which generates animation from sentences in English composed by a learner in order to visualize errors in them. In our learning environment, a learner is given a story in English with animation. Then, he/she is required to remind the story and to write it in English. Then the learning environment generates animation from the learner's sentences. The difference between the original animation and the learner's animation makes the errors in the learner's sentences clear. The learning environment, first, analyzes learner's inputs. When the results of the analysis have ambiguity or the results do not have enough information for animation generation, the environment removes the ambiguity or completes the results by referring to information of the original story the learner received. If the learner's inputs have a kind of errors that what a learner writes is different from the original story, the error is visualized as the difference between animation generated from the learner's inputs and the animation generated from the original story. This visualization of error in English sentences is a promising method to help a learner to be aware of his/her mistakes and correct them.
