The I-Series leads the student through clear, error-free, and unambiguous steps to accomplish tasks that produce a finished document, worksheet or database table. But the approach is not simply results-oriented; teaching how to accomplish a task is not enough for complete understanding and mastery. Prior to introducing steps, the authors discuss why each step is important and what role all the steps play in the overall plan for creating a document, workbook or database. The I-Series Applications textbooks strongly emphasize that students learn and master applications skills being actively engaged-by doing.
