Observing Student Reasoning and Proof
  Introduction | Inscribed Triangles | Problem Reflection #1 | Inscribed Triangle Continued | Problem Reflection #2 | Classroom Practice | Observe a Classroom | Your Journal


We've just observed a problem that involves teaching and learning about making conjectures, and finding proof relating to a triangle inscribed in a semi-circle. Now we would like to you to reflect on and answer at least one of the following questions in your journal.

Questions to write and reflect about:
  • In the content areas you teach, how do you use the concept of proof and develop an appreciation of that concept in your students?
  • How can you make reasoning and proof an integral part of mathematics instruction in your classroom? Be specific.
  • How can you help your students gain skill in reasoning systematically about a problem and building a case for their answers?
Three ways to write and reflect:
  • Use pen and paper.
  • Use a word processor.
  • Use the form below.
Be sure to save what you have written before you navigate out of the journal section.


Your work will be displayed in a printer-friendly format to enable you to print.

Thank you for writing in your journal. Please keep your entries in whatever format you choose -- you will find them useful for reference later.
