The development of Differentiation Intelligent Tutoring System (DifITS): example-tracing tutor approach
Sing, Felix Tiing Chuo1, Mohammad Nur Azhar Mazlan2, Kian Sam Hong3.
Calculus is an important branch of Mathematics for post-secondary
education in various disciplines. Students are introduced to Calculus
through the topic of Differentiation when they are in secondary school.
However, the analyses of the Additional Mathematics’ answer scripts of
the Sijil Pelajaran Malaysia (SPM) (Malaysian Certificate of Education
equivalent to GCE O’ Level) examination, has shown that students are not
doing well in this topic. Past empirical studies done locally and overseas
have also shown that many undergraduates face difficulties in learning
Calculus, thus hindering their undergraduate studies. Therefore, there is
a need to address this learning deficit, and with increasing class sizes in
school and tertiary institutions, a technology-enabled solution with minimal
human intervention, the Differentiation Intelligent Tutoring System (DifITS),
as proposed by this study, could be a viable approach to assist students’
learning for this subject. DifITS is promoted as a web-based tutor, using the
Example-tracing tutor approach to provide one-to-one tutoring and selfpaced
learning for the students. The Example-tracing tutor will be applied
using Cognitive Tutor Authoring Tools (CTAT). A behavioral graph will be
created to track students’ answers in order to provide hints and feedback.
In addition to enhanced learning, it is anticipated that DifITS will motivate
students as the tutoring mechanism involves animation to enable students
to visualize the procedural process of Differentiation. In addition, DifITS
will also focus on conceptual understanding through graphs to show the
rate of change and motion for the respective differentiation procedures.
