Modifying Dynamic Worksheets

Dynamic worksheets created with GeoGebra can easily be modified at a later date. Recall that an html-file and a ggb-file were created when you exported your worksheet. The html file is the textual part of your worksheet, the ggb file is your dynamic figure.

Modifying the Dynamic Figure with GeoGebra

To edit the interactive figure of your dynamic worksheet you need to open the ggb file (e.g. "ShapeSlopeFunction_worksheet.ggb") in GeoGebra. For example, you may want to change certain properties of objects (e.g. color, line thickness,...) to enhance the appearance of an interactive applet or add new elements.

After saving the ggb file, you should open your worksheet again in a web browser to see your updated version of the dynamic figure. Note that you should not change the name of your ggb file when saving; otherwise the dynamic figure won't be displayed in your html page any more.

Modifying the Text

In order to edit the text of a dynamic worksheet, you need to open its html file (e.g. "ShapeSlopeFunction.html") with an editor like for example NVU. There, you can modify the text of the dynamic worksheet, for example to set the color of certain expressions so that they match their representation in the dynamic figure. This increases the readability of the tasks and makes it easier for your students to find corresponding objects in the text and the applet. If you have a series of worksheets, you may also want to create hyperlinks to navigate between them. After saving the html file you should open the updated version with your web browser to check your changes.
