Course Policies:

Attendance: Attendance is absolutely essential to success in this class.  You are expected to attend every class; please notify the instructor if you know you are going to be absent.


Spending Time outside of Class: You can not expect to accomplish what you should from this course without spending time with the material outside of class. The usual expectation of 2 hours of study outside of class for every hour in class is a minimum. Please communicate with me as soon as possible if you are having trouble managing time - I want to help you get the most out of this course that you can.



Participants will:


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.


Participants will be able to:


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


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 create two mathematics lessons that integrate technology for use in their own classroom.  Students will also maintain a reflective journal starting with the initial class meeting.

Electronic Journal: As a part of this course, you are expected to maintain a reflective journal (preferably online). This journal is a log of your experiences within the course. It should include thoughts about new skills and accomplishments that you acquire; critical incidents that occur; and your thoughts and feelings about content (mathematics/number sense investigations) and technology. If you are experiencing difficulty keeping a journal, discuss it with your instructor who can provide you with additional suggestions and assistance.

Electronic Portfolio of Write-ups: Each person will develop a personal Web Page for the course. There will be a set of "Write-up" projects. These are the "homework" for the course. Each Write-up will be prepared as an HTML document (i.e. a Web Page document) and linked to your personal web page.

What is a write-up?

The "write-ups" represent your synthesis and presentation of a mathematics investigation you have done --usually under the direction of one of the assignments. The major point is that it convincingly communicates what you have found to be important from the investigation. A write-up should communicate the essential material you have synthesized from your investigation. The format could be entirely in a word-processing document. After all, an HTML document is basically a word processing document with links. The HTML format, however, can combine narrative, pictures, and program applications in a dynamic document. Write-ups should be posted to your personal Web Page. If you work as a team on a write-up, post the write-up into each team member's Web Page but label collaborative effort. Criteria should include correct mathematics, use of technology, and how well you communicate. "Solution" might be another word for "Write-up."

Electronic Portfolio of Lesson Plans: Participants are required to create two mathematics lessons that integrate technology for use in their own classroom. The "lessons" are to be your creations of material to incorporate technology into classroom lessons. The material can be individual lessons or a unit of material. Your criteria should be on its usability in your classroom or in other peoples classroom and something you feel good enough about to share with colleagues over the web.


Final Exam:  This is a very short exam that should show some synthesis of material learned in this course.
