AC 2007-1216: EMPHASIZING TEAMWORK AND COMMUNICATION SKILLS IN INTRODUCTORY CALCULUS COURSES

It is widely recognized that teamwork and communication skills are important outcomes in undergraduate engineering curricula. At our institution, the program goals in the mathematics department, which apply to our pre-engineering majors, also reflect the necessity of these skills. Student course exit surveys analyzed by the department indicated that communication skills, both written and oral, were not integrated into the introductory courses. In an effort to achieve our program goals, we have implemented team-based as well as individual activities that foster communication skills in our introductory calculus courses. In addition, these activities encourage the students to become active learners and to assume greater responsibility for their learning of mathematics. We have created both in-class and out-of-class activities to encourage the development of mathematical speaking and writing. Examples of team activities include group problem solving and assessment, assigning groups by related content so that determining the members of the group is itself a team activity, and team take-home exams with oral presentations. These activities promote students’ ability to contribute meaningfully to the functionality of a team. Further, team-based activities serve to deepen mathematical understanding. Individual activities such as differentiation/integration bees, one-minute papers, journals and essays are also utilized in class. The journal and essay topics cultivate student understanding of major content concepts and alert the instructors when student understanding is lacking. In this paper, we describe in detail the team-based and individual activities used. We will discuss class time-management, student attitudes, motivation challenges, and initial observations of student responses to these activities. We will also include preliminary assessment and reporting of the improvement in students’ mathematical communication skills and teamwork. Finally, we will outline our plans for further investigation of questions raised as a result of teaching with innovative activities designed to encourage teamwork and communication skills while allowing students to take a more active role in the learning of calculus.
