What is Maple T.A.?
• a mathematically intelligent assessment system
• supports multiple question types• algorithmic templates for questions• grade management

What makes it intelligent?
• many systems can't tell that ½ = 0.5• Maple T.A. accepts numbers, expressions,
formulas, functions, matrices, etc.• can use all the power of Maple to create
and grade questions (e.g., statistical distributions, MathML rendering)
• provides algorithmic variables

What are algorithmic variables?• variables can be assigned random values
– set a range such as x from [-1,1] in 0.01 increments– select a function from a list– create a matrix with a certain rank– a set of plots
• impose conditions– x > y or (x+y) > 0– rank ≠ 0

Algorithmic variables cont'd
• variables can be used anywhere in the question and the feedback
• diagram labels can also be algorithmic values

2010 | The Sky’s the Limit
• MATH courses added this year:− 135, 136, 137, 138, 235, 237− Algebra, Linear Algebra 1 & 2, Calculus 1, 2 & 3− ~1300 questions developed this year− weekly online assignments are now an integral part of these
courses
• Math Readiness Test− pilot this fall of ~300 students writing online

Content Management• Content is developed, tested, and
deployed by ISG staff with the help of Grad TAs and Co-op students.
• Questions are stored in central repositories, one per subject.– eliminates duplication
• Courses inherit the relevant repository content.

Lessons Learned• Within a repository, questions are
organized by topic.• Information fields include Author, Origin,
Course, question Type, Difficulty, and Keywords.
• A tag on each question allows us to tell exactly where it came from when used in an assignment.

Lessons Learned cont'd• Preparing students in how to enter their
answers is crucial.– Maple T.A. Ready? quiz
• Guidance and training needed for Instructors.– assignment policy consequences– remarking assignments
• Easy to access help.– online FAQ– email contact– division of responsibilities
