The primary school teacher encouraged her 24 students (half kindergarten, half first grade) to do a wide variety of projects based on their choosing.

Classroom infrastructure. The classroom had 2 Macintosh IIsi computers with access to the Internet through the university via T1 connection. During the entire semester, there was an undergraduate student assisting the teacher in the classroom. Both the teacher and the university student attended the training day.

Sample activities. The students sliced hard-boiled eggs to see how the MRI system would "slice" the egg. During MR image acquisitions, students worked in groups of six to eight students per group. So, while a group acquired an image on one computer, another group viewed the just acquired image on the second computer. The remaining groups worked on other activities, such as a writing exercise where they identified the three views (front, top, side) on the images that were previously acquired by their class. Figure 2 illustrates sample classroom activities.
