Hence the student is required ! to provide their own answer, rather than relying on their ! selection from a teacher-provided list. Using CAS is a natural ! tool for random generation of structured problems, establishing ! mathematical properties of student's answers (eg equivalence with ! a correct answer) and providing feedback.</p> ! <p>This system was conceived by <a ! href='email:ch...@sa...'>Chris Sangwin</a>, and is now part ! of the <a href='http://maths.york.ac.uk/serving_maths/'>Serving ! Mathematics in a distributed e-learning environment</a> ! project.</p> --- 9,52 ---- ?> ! <p>The STACK system is a computer aided assessment package for mathematics.</p> ! <p>In computer aided assessment (CAA), there are two classes of <em>question types</em>. ! <ul> ! <li><em>Teacher-provided answer questions</em><br /> ! In these questions, a student makes a selection from, or interacts with, potential answers ! which the teacher has selected. Examples include multiple choice, multiple response and so on. ! </li> ! <li><em>Student-provided answer questions</em><br /> ! In these questions the student's answer contains the content. It is not a selection. ! Examples of these are numeric questions. ! </li> ! </ul> ! ! STACK concentrates on student-provided answers which are ! mathematical expressions. For example, a student might respond ! to a question with a polynomial or matrix. Essantially STACK ! asks for mathematical expressions and evaluates these using ! computer algebra. The prototype test is the following ! pseudo-code. ! <pre>If ! simplify(student_answer-teacher_answer) = 0 ! then ! mark = 1, ! else ! mark = 0. ! </pre> ! ! A CAS provides a library of functions with which to manipulate ! students' answers and generate outcomes such as providing ! feedback. Establishing algebraic equivalence with a correct ! answer is only one kind of manipluation which is possible. ! Using CAS can also help generate random yet structured problems, ! and corresponding worked solutions. ! ! <p>In STACK a lot of attention has been paid to allowing teachers to author ! and manage their own questions. You can try this for yourself by looking ! at the question bank demo, authoring guide and other options available here.</p> ! ! <!-- Please do not remove this public credit.
