Assessment Methods for Core Learning Goals:All Core Critical Thinking and Problem Solving, College Level Mathematics or Science, and Discipline-Specific Course Objectives will be assessed as follows:
The student will apply mathematical concepts and principles to identify and solve problems presented through informal assessment, such as oral communication among students and between teacher and students and, for the core, formal assessment using open-ended questions reflecting theoretical and applied situations.
Reference, Resource, or Learning Materials to be used by Students:There is a departmentally selected textbook and calculator. The instructor will provide specific details for each section. See Course Format.
Teaching Methods EmployedPrimary teaching methods are lecture, recitation, problem solving, and class discussion as appropriate.
