Enhancing College Algebra with Interactive Software
Having taught MAT151 (College Algebra) in both Fall 2011 and Spring 2012, I noticed that a fair number of students were having difficulty understanding the concept of a function. Many failed to recognize how a function's output value varies in a predictable way based on changes to its input value, and most had a hard time connecting the geometric, tabular, verbal and equation representations of a function. Developing this understanding is critical to student success in MAT151 and subsequent math classes.
