  Abstract: Students who struggle to solve problems often utilize a variety of creative solution strategies that go beyond mimicking previously worked examples. These strategies are sometimes incorrect generalizations of a particular example or invented based on superficial properties of the problem. Recently, advances in the open-source online homework system WeBWorK have allowed us to capture not only the final answer that students provide but also the work, including incorrect attempts, used to complete the problem. We will share how we have used the system to better understand and characterize how calculus students with weak understandings of function composition attempt to solve contextualized, e.g. extreme value and rate, problems in the course. In addition, we will share how we are using this information and technology to provide interactive interventions focused on these students' weaknesses.
