2. Spring 2007 2R. Smith - University of St Thomas - Minnesota Assessment Is this class is teaching you what it should?Is this class is teaching you what it should? How can UST answer this?How can UST answer this? –Involves course objectives –The Department is implementing a strategy to assess students’ achievement of course objectives –Specifically: exam questions Course ObjectivesCourse Objectives –Understand programming languages (C) and application packages (Matlab) and their differences –Write programs in C; solve problems in Matlab –Alternative methods of solving the ‘same’ problems, assessing effort, effectiveness, machine efficiency –Assess appropriate use of computer tools (languages, applications) to solve a particular problem

3. Spring 2007 3R. Smith - University of St Thomas - Minnesota Assessment Topics for the Exam Write programs in C; solve problems in MatlabWrite programs in C; solve problems in Matlab Differences between C and MatlabDifferences between C and Matlab –Compiled versus interpreted –Little program (.exe) runs by itself vs.m file with Matlab –Different syntaxes – Different error detection Assessing Differences for ‘same’ problemAssessing Differences for ‘same’ problem –effort, –effectiveness, –machine efficiency Assess appropriate use of languages vs applications to solve particular problemsAssess appropriate use of languages vs applications to solve particular problems –Which is “best” ??
