We conducted a teaching experiment to examine the learning conditions and problem-solving performance of students and understand their misconceptions and difficulties in different areas of learning. Teacher journals review teaching techniques and effective teaching methods to assist students in forming complete and systematic concepts of circles and in solving problems. The subjects in this study comprised a sixth-grade class of students at a public elementary school in Central Taiwan and their homeroom teacher. The course content focused on the concepts of determining the area of complex figures with circles, as introduced in sixth-grade mathematics in the Grade 1-9 Curriculum Guidelines. We referred to math teaching materials and guidelines to design the course. The collected and analyzed data included: (1) teacher-student interactions during class, (2) the math worksheet performance of students, and (3) after-class interview records. We verified teaching effectiveness by using the worksheet scores and qualitatively analyzed the misconceptions of students. The findings of this study indicate the following: (1) the teaching materials designed using learning trajectories include the Basic Composing Elements of Circles, Understanding the Circle Area Formula, Cutting and Shifting Techniques to Calculate Area, Understanding the Distributive Law and Marking Areas with Symbols, and Filling in and Other Strategies, (2) students with different levels of cognition displayed varying performance on the area worksheets, and (3) after retrospective reflections on the teaching experiment, the teacher’s behavior changed with regard to understanding the conceptions of the students, teaching methods, and curricular design. en_US dc.identifier 174C7BB0-9B55-28B3-48F3-DB8507DF64D3 dc.identifier.uri http://rportal.lib.ntnu.edu.tw:80/handle/20.500.12235/84032 dc.language 中文 dc.publisher 國立臺灣師範大學 zh_tw dc.publisher National Taiwan Normal University en_US dc.relation 61(1)，1-41 dc.relation.ispartof 教育科學研究期刊 zh_tw dc.subject.other 面積 zh_tw dc.subject.other 圓形 zh_tw dc.subject.other 複合圖形 zh_tw dc.subject.other 學習軌道 zh_tw dc.subject.other area en_US dc.subject.other circle en_US dc.subject.other complex figure en_US dc.subject.other learning trajectories en_US dc.title 圓形複合圖形面積解題學習軌道之教學實驗研究 zh-tw dc.title.alternative Teaching Students How to Calculate the Area of Complex Figures With Circles by Using Learning Trajectories zh_tw
