ab: Summary: Assessment and feedback are important parts of the teaching and
learning of mathematics; and in general, the process can benefit by the
introduction of technology. MathDIP is a web-platform which provides
automatic evaluation and feedback of each step of the solution of a
math problem. The system incorporates a Computer Algebra System to
perform the evaluation and a mathematical expression editor which
allows the user to interact with the system using his/her own
handwriting. This paper reports on the design, development and
evaluation of the system. The usability results of its implementation
on an Introductory University Mathematics course show good performance
in design and functionality issues. Also, results show that in general,
the students participating in the study have a high level of acceptance
for the system and perceive that its use motivated and strengthened
their learning of the specific math topics covered in the course.
