The
field of education has the potential to
be transformed by the
internet and intelligent computer systems. Evidence for the first stage
of this transformation is abundant, from the Stanford online AI and
Machine Learning courses to web sites such as Kahn Academy that offer
on line lessons and drills. However, the delivery of
instruction via web-connected devices is merely a precondition for what
may become an even more fundamental transformation: the
personalization of education.
In traditional classroom settings, teachers must divide their attention
and time among many students and hence have limited ability to observe
and customize instruction to individuals. Even in one-on-one tutoring
sessions, teachers rely on intuition and experience to choose the
material and stye of instruction that they believe would provide the
greatest benefit given the student's current state of understanding.
In order both to assist human teachers in traditional classroom
environments and to improve automated tutoring systems to match the
capabilities of expert human tutors, one would like to develop formal
approaches that can:
- exploit
subtle aspects of a
student's behavior---such as facial expressions, fixation sequences,
response latencies, and errors---to make explicit inferences about the
student's latent state of knowledge and understanding;
- leverage the latent state to
design teaching policies and methodologies that will optimize the
student's knowledge acquisition, retention, and understanding; and
- personalize instruction by
providing material and interaction suited to the capabilities and
preferences of the student.
Machine learning provides a rich set of tools, extending classical
psychometric approaches, for data-driven latent state inference, policy
optimization, and personalization. Years ago, it would have
been difficult to obtain enough data for a machine learning approach.
However, online interactions with students have become commonplace, and
these interactions yield a wealth of data. The data to be mined go
beyond what is typed: Cameras and microphones are ubiquitous on
portable devices, allowing for the exploitation of subtle video and
audio cues. Because web-based instruction offers data from a
potentially vast collection of diverse learners, the population of
learners should serve useful in drawing inferences about individual
learners.
Mining the vast datasets on teaching and learning that emerge over the
coming years may both yield important insights into effective teaching
strategies and also deliver practical tools to assist both human and
automated teachers.
The goal of this workshop is to bring together researchers in machine
learning, data mining, and computational statistics with researchers in
education, psychometrics, intelligent tutoring systems, and designers
of web-based instructional software. Although a relatively
young journal and conference on educational data mining has been
established (educationaldatamining.org), there are exciting
opportunities to enhance interactions between cognitive scientists
interested in education and machine learning theoreticians.
