Professional Portfolio Showing Growth in Geometric Understanding

Due February 25, 2008

The portfolio is to be used as a way to capture and document, as well as share, your personal growth in geometric understanding about two areas: 2-D geometry and 3-D geometry. One of the main goals of the portfolio is to demonstrate knowledge at level 2 of Van Hiele's geometric thinking for each area.

What Should Go Into Your Portfolio?

Each portfolio will be unique. It is up to you to decide what evidence to include that shows you are working and making progress toward a deeper understanding of geometry concepts, and appropriate ways to teach these ideas to your students. The items you include should be things that clearly demonstrate your understanding of transformations and spatial visualization. The items may show work you are particularly proud of or work that you have struggled to understand.

Items should be purposively selected—include 4 to 6- at least one per section.

Include a cover letter. The cover letter should be written from you to the reader. It should describe changes in your understandings, attitudes, or teaching practices in relationship to geometry, and identify some of your goals or needs for the future. You may also want to list and briefly describe the contents of the portfolio.

Each item in the portfolio should clearly state what it is and why it was selected. What does this item show or tell the reader about your teaching of mathematics or about your own learning of mathematics? You may want to include a separate reflection page for each item or just build the reflection into the item itself.

Evaluation of Your Portfolio

Your portfolio will be reviewed and evaluated on the following criteria.

•Captures “flavor” of teaching and learning geometry.

•Demonstrates professional growth.

•Cover letter that describes changes in understandings, attitudes, practices, and identifies goals.

• Includes 4 to 6 distinct items. Each clearly states what it is and why it was selected and describes impact on teaching and learning. Each section should demonstrate that you have knowledge at level 2 of Van Hiele's geometric thinking, even if your students are not working at this level.

• Well organized, appealing, clearly presented.
