| Sumario: | The evaluative framework of statistics textbooks developed by George W. Cobb is extended to six online instructional materials. These materials are typical of the diversity of introductory statistics resources available on the Internet and range from electronic textbooks and courseware that make considerable use of interactive learning objects and environments to course web sites with limited interactive capabilities. The instructional materials are examined in light of recent cognitive research that highlights the value of learning from examples, the importance of authentic problem solving in enhancing knowledge in use and skill acquisition, and the use of feedback to maximize learning opportunities.
