| Summary: | 碩士 === 國立屏東教育大學 === 資訊科學系 === 97 === This research constructs an auto-reply system of questions and answers of mathematic speed unit for elementary schools. This system offers auto-reply functions which can solve students the questions of the speed unit and immediately obtain accurate answers. The major findings and conclusions are as follows.
1.According to Robert Mills Gagne''s study stratum theory, the researcher develops the study stratum of the mathematic speed unit. Then, the question documents, keywords, and answers of six levels are developed for the auto-reply system of questions and answers.
2.This research utilizes the term-weighting approach and the cosine similarity measure method, which can find the questions that are similar to the keywords the user keys in. The development tool of the internet system, asp.net, is used to develop an auto-reply system of questions and answers.
3.The auto-reply system includes mainly three modules, which are “keywords input mechanism”, “similar questions auto-reply mechanism”, and “question-answers mechanism”.
4.This auto-reply system can effectively solve the questions of the speed unit and improve student''s learning effects and confidence.
5.Teachers should train student''s ability for independent study and encourage students to find answers of questions.
6.The teacher should not be only an onlooker, but also get involved and deal with the problems, when students use this system.
7.The future research is to apply the auto-reply system in other units or subjects, and to combine with digital textbooks and an assessment system to be a complete teaching system.
