Teaching Methods

This class is taught mainly through lecture and practice. Students are given comprehensive overviews of each section, which are followed by in-class practice. Students are often given the opportunity to perform their skills in front of the class where their peers can confirm solutions or offer their own suggestions. Daily assignments are a major part of the mathematical learning process. Students are expected to complete every assignment and give full participation in class for successful completion of this course.

 

Assessment

Students will be assessed with the following:

  • Daily Assignments
  • Quizzes
  • Chapter and Semester Exams
  • Renaissance Learning Web-Based Software Practice and Tests
