Expectations Table of Contents The webpage would not require supplemental software. The questions would be self-generating. The webpage would be interactive. To create a mathematical lesson on the internet. Students would have another method to learn.

Outcomes Table of Contents Calling external windows with JavaScript. Moving objects with Dynamic HTML. Writing a random number generator in JavaScript. I learned the following: Making a Power-Point presentation. Making a graph with Excel.

Successes Table of Contents Most of the students passed the quiz. Pages were dynamic, yet accessible from our library. Taught the topic with another method. Met California standards for Algebra 1 and Geometry. Completed CTAP 295. Became a CTAP mentor.

Shortcomings Table of Contents The library was the only connection at our school. We never got “Fetch” to work. The library was connected for approximately one month. My classroom was never connected. Not enough time. So many other things to do at the school.

Summary Table of Contents It was enjoyable to create the web page. CTAP forced me to sit down and learn more about JavaScript and Dynamic HTML. At our school, we have just finished the first year of reconstruction as a digital high school. For most of the classes, technology is something we talk about. We can occasionally arrange a trip to the library. But we really don’t know yet how well these web pages can be used to teach students.
