    Abstract: 近年來,擬題活動逐漸受到國際重視。出一個數學題目的歷程,即為數學擬題;其中又以自由擬題的出題形式最無限制。在台灣學童數學學習成就高、興致卻低落的情況之下,數學自由擬題可能是一改善的管道,也可能觸發更主動、深入的思考。





    ;Problem-posing and collaboration have been recently considered as two important issues by mathematics education researchers around the world. However, academic researchers address the benefits of collaborative learning while school teachers point out that the students’ widely varied abilities and teachers’ time constraints will have an influence on the quality of the collaborative effects. In addition, “high achievement but low interest” is still an unsolved problem in mathematics education in Taiwan. Therefore, the two research questions are: 1) To what extend do student’s problem-posing improve? 2) What collaborative effects do suggestions from peers and teachers have on the quality of students’ problems?

    The major characteristic of this problem-posing activity is “one problem, many revised versions”. There are two stages: the “peer-help” stage is from the first to the fourth version, and the “teacher-guide” stage is between the fourth and the fifth version. Each fifth grader is encouraged to give suggestions to his or her classmates and to help each other pose a mathematic problem. After the fourth version is completed, the teacher will provide guidance to problems that need further improvement.

    This study used a mixed method. Two sets of rubrics were generated to evaluate the quality of the problems by posers and suggestions by peers. The results were analyzed in a quantitative fashion. Problems between versions, interviews, and worksheets data were used to analyze qualitatively the progress they made.

    The result shows that: 1) The free problem-posing activity produced problems presented with wordiness, inconvenient numbers, and high relations with students’ life experience or other subjects. 2) The student-posed problems made significant progress throughout the five-version process. Each received different kinds of help from the “peer-help” stage and “teacher-guide” stage. In particular, the teacher had a significant influence on solvability and readability of the problems, while peers helped on the connection to their daily life, the refinement, and the concept level of the problems.

    Debates and implications for school teaching are provided. The free problem-posing has its virtues in engaging students in more active and deeper thoughts, but has its drawbacks in developing lengthy and context-rich problems which goes against the current practice among professional mathematicians. The different collaborative design and its effects on peer collaboration provide a promising picture for teacher practitioners. Future study can focus on the refinement of the two sets of rubrics. The potential of problem posing on student’s mathematics communication ability is also discussed.
