The Implementation and Evaluation of OASIS: A Web-Based Learning and Assessment Tool for Large Classes

This paper describes a Web-based learning and assessment tool developed and implemented over a five-year period. Used predominately with first- and second-year students for skills practice and summative assessment, the tool delivers individualized tasks, marks student responses, supplies students with prompt feedback, and logs student activity. Interviews with instructors indicated that the software had enabled them to manage workloads in spite of rising class sizes and that student learning, based on observation and assessment results, had been enhanced rather than compromised. Student surveys, interviews, focus-group discussions, and informal feedback showed that students found the software easy to use and felt it helped them improve their skills and understanding. Student activity logs provided an insight into student study habits and confirmed the motivating power of assessment.
