Instant qualitative feedback system on the basis of text data: Its use and future possibility

This paper demonstrates the future possibility to integrate "Instant Quantitative Feedback System” into any educational or other relevant settings. Our study concerns how the instant feedback system on text data collected from the audience had an effect on learner's ore presenter's attitude, comparing the effects of the two types of the instant feedback system: the "clicker" type quantitative feedback and the qualitative feedback based on the text data. Our study was carried out in two different types of English classes of the Japanese national university. One class is a high-level class and the other is a low level class. Our study suggests that the proposed qualitative feedback system is useful in two ways: For low-level learners, the system encourages them to express their ideas and opinions better in free text style and to understand how the audience felt about their presentation. For high-level learners, the qualitative feedback system seems to provide them with the opportunities to summarize their ideas and opinions more deeply.
