Continuous Attitudinal Response Technology (CART) is an alternative approach to testing students' instantaneous response to teacher behaviors in the classroom. The system uses a microcomputer and video technology device that allows researchers to measure subjects' instantaneous responses to static and continuous stimuli, graphic or verbal. A typical session takes place in a focus-group facility or any environment conducive to small group interaction, such as a classroom. CART has proved useful in combining qualitative aspects of small group research and quantitative aspects of survey research. A pilot test of teacher story-telling using CART (with 96 subjects) provided support for previous findings and provided additional information about the differential impact of different story types on students' instantaneous learning. CART has also been used to test implicit communication theory in the classroom. A study determined 12 undergraduate subjects' emotional responses to an educational film about public speaking via CART. Results indicated that subjects' comprehension scores were lowest for material covered in the videotape when pleasure levels were lowest. Efforts are underway to expand research in communication and education using CART technology. (Thirty-seven references are attached.) (RS)
