As they explore and discover, children learn about numbers, shapes, sizes, patterns, and problem-solving. As students analyze real world events in scientific and mathematical terms, the principles of physics become more meaningful and relevant. Because of the difficult terrain, students must figure out optimal combinations of using a truck, ultralight aircraft, and hiking, taking into consideration fuel, payload, weight, and different starting points. The students use a combination of the random-access videodisk, maps, and computers to generate alternative solutions. Fifth-grade students of average ability have been fascinated with the task, and have been motivated to solve it with solutions that require over 15 steps.
Students learn to collect, analyze, and report data that is used by the scientists.
And in the MicroObservatory project at Harvard University, secondary school students are using remote computer-controlled optical telescopes to do their own research projects in astronomy. Increasing numbers of multimedia software programs are focused on developing the critical and creative thinking skills of students. The program assesses individual strengths and weaknesses in cognition and offers strategies to strengthen intellectual powers. It is appropriate for students at all ability levels. A number of recreational games also have much to offer in the way of new intellectual challenges.
