Real-time analysis of student comprehension: An assessment of electronic student response technology in an introductory earth science course

Electronic student response technologies (SRT) are capable of assessing teaching and learning methods in real time, and they offer an exceptional means of introducing active learning protocols in classes with large enrollments. These wireless systems allow students to key in responses with remote control units to questions posed by an instructor in the classroom. Student responses then are displayed in real time, allowing both students and instructors to gauge student comprehension instantaneously. From Spring 2002 to Spring 2003, we utilized SRT in 4 sections of a high-enrollment introductory Earth Science course (Geosc 020: Planet Earth) at Penn State University. We conducted a multi-faceted assessment of the use of SRT in our course that included quantitative and qualitative perception data from students enrolled in the course and faculty/administrator visitors to our classroom. Our preliminary assessment of the pedagogical merits of SRT in our course suggests that this technology is an effective tool for introductory geoscience education.
