The article presents a study which investigates the responses of students to conceptual multiple choice questions that were answered using an electronic personal response system called conceptests. It notes that the study has used conceptests from geosciences questions. It examines the conceptest response pattern of the students to evaluate the efficacy of principles and methods of instruction in a general education classroom setting. data from the study were sorted by gender and race to demonstrate the distribution of the students' responses in the four-paired response categories, correct-incorrect, twice incorrect, incorrect-correct, and twice correct. Results show that the conceptest response patterns from electronic response systems can be use to evaluate teaching technique.

" A new type of Student Response System (SRS) based up on the latest wireless technologies and hand held mobile devices has been developed to enhance active learning methods and assess students' understanding. The key services involve a set of XML technologies, web services and modern mobile devices. A group consisting of engineers, scientists and instructors with pedagogical competence, from seven European countries has designed the services. The new SRS provides intuitive control interfaces, which an instructor quickly learns how to use, provides more flexible and cheaper response services than existing on-site technologies based upon so-called "clickers", since it uses the Wi-Fi or mobile network to provide responses from students. The technology may be used for in-class, laboratory and distance training purposes, the latter being an entirely new option in SRS technology. We report experiences from using this SRS technology in physics teaching in engineering classes, as well as in distance learning in Europe. [ABSTRACT FROM AUTHOR]"
