This study is a qualitative case study focusing on the question “What are the processes of learning in a Computer Algebra System (CAS) environment for college students learning calculus?” The study is designed to research the impact on student learning of new and revolutionary software available for mathematics education. Research in CAS has focused on outcome-based studies and more philosophical work on the curriculum and assessment implications of CAS. Missing are studies which look at what exactly happens when students try to learn mathematics in a CAS environment: What does CAS learning look like on a day-to-day basis? and What does CAS learning look like across the period of a ten-week course? The importance of investigating these processes lies in understanding the impact of CAS on learning so that an appropriate balance can be found in the integration of technology into teaching ensuring that the merits of traditional methods are not lost and that the merits and demerits of CAS use are fully understood. The primary data for the study consists of audio and video of tape of a group of students in a college course learning calculus using CAS software. This data was supplemented by interviews with the students as well as analysis of the students’ homework and tests. Analysis of the data via Rotman Model of Mathematical Understanding provides a lens through which to view the place of technology in the CAS classroom and through which to view the journey of each student across the quarter. The Pirie-Kieren Model for the Growth of Mathematical Understanding is then mobilised as a lens through which to examine specific learning episodes as they occur in the classroom. As well as providing examples of student learning, the broader conclusions of the study are (i) that the framing and introduction of technology at the beginning of an instruction period impacts crucially on student behaviour and use of technology throughout that period and (ii) that while students will naturally experiment in a CAS environment intervention is probably required for them to develop sophistication in their experimental behaviour and strategies.
