The following information comes from the named instructor and should describe characteristics general to courses as taught by this instructor. Individual sections of specific courses will deviate from this description in some respects.

Class Format

Face-to-face class time consists of traditional lectures, demonstrations, discussions, quizzes, class activities and lab assignments. Online students are expected to learn more independently, relying more heavily on the textbook, discussion board interactions (where I do my active teaching in my online courses), lecture slides and short lecture videos for content. Canvas is used to submit homework, take unit exams and check grades in both online and face-to-face classes. Due dates are provided on the Canvas Calendar (online classes) or on the detailed Class Schedule (face-to-face classes).

Resource Use

Textbook: Extensive
Calculator: Extensive (face-to-face only)
Software: Limited

The textbook is online and free! Anyone desiring a hard copy may feel free to print it at his/her expense. Face-to-face students also need a scientific calculator (does NOT have to be a graphic calculator).


Unit exams and the comprehensive final exam comprise a majority of the grade for both online and face-to-face students. In addition, students are also required to submit a Student Learning Outcomes Pre-test and Post-test (only the post-test counts toward the student’s grade). Face-to-face students also take short weekly quizzes. Online students must take the final exam in the JCCC Testing Center or arrange an off-site proctor to be approved by the instructor. Face-to-face students must take an in-class final at the scheduled time during Finals Week.

Homework Policy

There are explicit homework assignments that may be taken multiple times for mastery. There are also ongoing implicit homework assignments that include reading the textbook and using the extensive and detailed study guides to prepare for exams.

Attendance Policy

There are no attendance points to be gained or lost. Missing face-to-face classes usually negatively affects the learning and understanding of material, which then results in lower exam scores. For online students, failing to frequently log into the courses may result in missed announcements, emails or due dates. No late work is accepted. Students are allowed one and only one make-up unit exam during the term. There is no make-up for the final exam and everyone must take it. Face-to-face students will have their lowest quiz score and two lowest lab scores dropped.


My office hours are provided on the first day of classes. Additional times may also be arranged. Emails sent to me should be submitted through Canvas to my Canvas address. Help is also provided on designated Canvas discussion boards. It typically takes me much less than 12 hrs to respond to emails or discussion posts.
