Table 4-2 lists the World Wide Web sites you can visit to learn more about these projects. The Curry School of Education has a frog dissection tutorial that shows how the World Wide Web can host highly interactive educational activities over the Internet. In one part of the tutorial, for example, the student clicks places on a picture of a frog to mark the beginning and ending of an incision. If the student is wrong, feedback is provided. When the student gets the answer right, the incision is made, and another picture shows the results.
Students can also formulate hypotheses and conduct statistical tests.
As illustrated below, there is a teacher's lounge where you can discuss the latest trends with other biology teachers. The search engine lets you perform keyword searches of all the documents in the NABT site. In a textbook, students are limited to a static photo that shows only one position. On the Web, using active technologies such as Sun's Java, Macromedia's Shockwave, and Microsoft's ActiveX, students can rotate chemical models by clicking and dragging with a mouse. For example, figure 4-13 shows different stages in the rotation of a model of a benzene molecule on a Java Web page.
