ActivChemistry™ Website: http://heg-school.awl.com/bc/companion/actchem/ac.htm. Available on CD-ROM, this interactive software-now with twelve tutorial lessons on major chemistry topics-allows students to easily conduct simulations at both the bulk and atomic level, see relationships between the macroscopic and microscopic worlds, and have fun while tackling often difficult content. Students are initially guided through the main concepts of the general chemistry course via lessons based on engaging, real-life situations. With this understanding of basic concepts, they are then encouraged to explore more freely in the Work Bench area. Tutorial lessons were written by expert general chemistry instructors. A Lesson Author’s Guide is built into the program, and illustrates how, with simple word processing ability, anyone can easily customize or write their own lessons. For use with any general chemistry textbook, ActivChemistry™ is an ideal complement to lecture or lab and an excellent study tool for students.
