I will report on outcomes of an ongoing project to establish the use of the Numbas e-assessment system in support of the teaching of Chemistry at Newcastle. Objectives of the project are; (i) to support teachers of Chemistry in developing advanced skills with Numbas; (ii) to deliver a range of model Numbas tests which will be used as formative assessment tasks in support of Chemistry. I will explain how Numbas is allowing us to extend our support for numerical tasks connected to skills-based (practical, laboratory) exercises. I will describe how we are seeking to extend the range of other tasks to which Numbas can be applied.
