數學解題問答系統之建置與評估

Abstract

本研究旨在設計數學解題問答系統，讓學生對詳解中有問題的地方更直覺做記號方便提問，降低學生提問時的困難，並評估系統在操作上的易用性。

本研究參與者為台南市某公立國中八年級學生一班30人。學習活動需五節課的時間，分五天利用早自修完成。以八年級下學期數學第三章3-2「三角形的全等性質」為學習內容，整理國中該單元中的證明題形成題庫，並依照難易程度不同分為五類題庫，作為本次學習活動的教材內容。除探討系統滿意度外，亦蒐集前後測成績，探討透過本系統進行課外練習的學習活動是否能增加熟練度，是否能提升學習成就。學習活動結束後，讓學生填寫系統滿意度與幾何證明學習態度問卷。

研究結果顯示多數學生表示本系統容易操作。學生遇到難以表達的困難點，使用圖片模式提問的比例會上升。透過錄音模式提問則是喜好度最低的一種方式。整體來說，本數學解題問答系統操作上易用性高，學生對於利用問答系統進行幾何學習活動持正向的態度，並能提升幾何學習成效。

The purpose of this research was to design a questioning system for mathematical problem solving to allow students to explain their problem more intuitive and easy to do a question mark, reducing the difficulty of students asking questions, and to assess the system on the operating ease of use.

Participants are 30 eight grade students. Research instruments included a question pool database, a geometry learning attitude questionnaire, and an achievement test.

On the basis of data collected at this stage, following results were found. When the participating students encounter difficulties point difficult to express, use an image mode questioning proportion will rise. Through questioning the recording mode is the lowest degree of preference way. The research results indicate that the majority of participating students said our questioning system is easy to operate and hold a positive attitude toward the geometric learning activities. The achievement test showed that learning activities through the questioning system can enhance the effectiveness of learning geometry.
