Using networked tools to enhance student success rates in large classes

A two-year project to study and assess the use of technology to enhance student learning and performance is described. Preliminary results are encouraging and will serve to guide future direction of the project. The tools consist of an asynchronous learning network (ALN) for student assistance and of a networked software system to implement a computer-assisted personalized approach (CAPA) for assignments, quizzes, and examinations. The fraction of students performing well enough to achieve a grade of 2.5 or higher is our measure of success. The use of technology has permitted a reallocation of instructors' and teaching assistants' time, shifting it from repetitive jobs such as grading and record-keeping to tasks more directly related to student achievement. The prompt and accurate feedback which this technology provides can be used in large lecture courses in several ways to improve student success rates. Having information on students' performance and difficulties at an instructor's fingertips also provides an opportunity for problems to be addressed in a timely manner.
