In fall 2014, we organized ASSESS, the first workshop on data mining for educational assessment and feedback, at KDD 2014 [link]. The workshop brought together a total of 80 participants including education psychologists, computer scientists and practitioners under one roof and led to a thoughtful discussion. We have put together a white paper which captures our key discussions from the workshop. The paper primarily discusses why assessments are important, what is the state of the art and what goals should we pursue as a community. It is a brief exposition and serves as a starting point for a discussion to set the agenda for the next decade.
Why are assessments important?
Automated and semi-automated assessments are a key to scaling learning, validating pedagogical innovations, and delivering socio-economic benefits of learning.
- Practice and Feedback: Whether considering large-scale learning for vocational training or non-vocational education, automating delivery of high-quality content is not enough. We need to be able to automate or semi-automate assessments for formative purposes. Substantial evidence indicates that learning is enhanced through doing assignments and obtaining feedback on one’s attempts. In addition, the so-called “testing effect” demonstrates that repeated testing with feedback enhances students long-term retention of information. By automating assessments, students can get real-time feedback on their learning in a way that scales with the number of students. Automated assessments may become, in some sense, “automated teaching assistants”.
- Education Pedagogy: There is a great need to understand which teaching/learning/delivery models of pedagogy are better than others, especially with new emerging modes and platforms for education. To understand the impact of and compare different pedagogies, we need assessments that can summatively measure learning outcomes precisely and accurately. Without valid assessments, empirical research on learning and pedagogy becomes questionable.
- Learning to socio-economic mobility: For learners that seek vocational benefits, there need to be scalable ways of measuring and certifying learning so that they may garner socio-economic benefits from what they’ve learnt. There need to be scalable ways of measuring learning so as to predict the KSOAs (knowledge, skills and other abilities) of learners to do specific tasks. This will help both learners and employers by driving meritocracy in labor markets through reduced information asymmetries and transaction costs. Matching of people to jobs can become more efficient.
