Towards digitalisation of summative and formative assessments in academic teaching of statistics
This work provides a domain-specific tool for improving assessment in academic statistics teaching, but it is incremental as it builds on existing systems.
The paper addresses the lack of support for complex exercises in web-based assessment systems, particularly in statistics, by presenting conceptual requirements and a fully implemented solution, and reports its use in large university lectures for formative and summative assessments.
Web-based systems for assessment or homework are commonly used in many different domains. Several studies show that these systems can have positive effects on learning outcomes. Many research efforts also have made these systems quite flexible with respect to different item formats and exercise styles. However, there is still a lack of support for complex exercises in several domains at university level. Although there are systems that allow for quite sophisticated operations for generating exercise contents, there is less support for using similar operations for evaluating students' input and for feedback generation. This paper elaborates on filling this gap in the specific case of statistics. We present both the conceptional requirements for this specific domain as well as a fully implemented solution. Furthermore, we report on using this solution for formative and summative assessments in lectures with large numbers of participants at a big university.
