Outline | Participant Pages

1. GOALS ADDRESSED

Participants will:

2. IMPROVEMENT PRACTICES

Participants will gain knowledge and practice in developing instructional activities and strategies for teaching number concepts in the middle school classroom in order to positively affect student achievement. Participants will also improve their own mathematical competencies in the area of arithmetic.

3. COMPETENCIES

Participants will be able to:

4. PERFORMANCE INDICATORS

As a result of this course, participants will demonstrate their ability to:

5. PREPARATION PHASE

Dates: Fall 2002
Instructor: Dr. Wilson/Dr. Gootman
Location: UGA campus
Strategies: Internet exploration, electronic and classroom discussions, lectures, exploration of mathematical investigations, investigation write-ups, collaborative brainstorming, lesson planning, presentations

6. ASSESSMENT

Participants will be assessed on the content and quality of their online portfolios. Feedback and suggested modifications for a select number of write-ups will be provided throughout the workshop. Assessment will be based on use of representation, analysis, appropriate selection and use of technological tools, creation of extensions, and accuracy of mathematics. In addition to the investigation write-ups, the participants will also create a mathematics lesson that integrates technology and number concepts for use in their own classroom. An end-of-course exam will be given to assess students on their mastery of mathematical abilities in the area of number concepts.
