The Science and Mathematics Initiative for Learning Enhancement, or SMILE program, is a project of the Illinois Institute of Technology (IIT) Center and is funded by a grant from the Lucent Technologies Foundation. The program is "designed to enhance the elementary and high school learning of Science and Mathematics through the use of the phenomenological approach." On this website, the project posts the lesson plans developed by teacher participants at its summer sessions held between 1986 and 1997. The lessons, available free online, are also available in print or CD for purchase and include a list of the materials needed, suggested activities and expected outcomes. The Mathematics section includes lessons on Geometry and Measurement, Patterns and Logic, Probability and Statistics, Recreational and Creative Math, Practical and Applied Math, Graphs and Visuals, Algebra and Trigonometry, and Arithmetic. Submissions from participants after 1997 are less detailed, offering a brief single concept lesson or idea. More recent additions are posted in the Contributed Lessons section, which welcomes guest contributions from educators, parents and others interested in contributing concept lessons which use the phenomenological approach to learning. Visitors may also find some helpful resources in the Web-based resources section. Also posted are class notes from courses offered through the SMILE teacher training program.
