This document discusses key issues from the literature around formative e-assessment. It explores definitions of formative assessment and the roles of teachers and learners. There is some debate around whether formative assessment is an event or ongoing process, and whether feedback should be viewed as a transmission of information or a more complex two-way process. The document also examines what counts as evidence in formative e-assessment and whether certain practices labeled as formative assessment are actually examples of evidence being generated for serial summative assessment purposes.
