Supporting classroom discussion with technology: A case study in environmental science

This paper describes the fruits of a partnership between two academic departments: offerings of environmental science and resource management courses technologically enhanced with a classroom interaction system developed in the computer science department. The system allowed the instructors to adopt a style of teaching - by engaging the vast majority of students during lecture - that would have been difficult without the electronic support. The main contributions of this work lie in the novel techniques and teaching philosophy used in creating materials, especially in-class student activities, to take advantage of the system´s capabilities, and in the new usage model employed in these courses. Specifically, emphasis was placed upon using the system to encourage all students to directly participate in classroom discussions; in previous deployments it was used to support other pedagogical goals. Feedback data confirms that we were successful in devising classroom activities to engage students, create an atmosphere of participation, and accomplish some additional pedagogical goals of the instructors. In this paper, we describe the technology and pedagogy used in the courses, and evaluate the courses based upon the body of collected data, including in-class observation notes, digital ink artifacts created by students and instructors, instructor analyses, and student surveys.
