ASSESMENT OF STUDENT LEARNING Achievement of course objectives will be assessed using long exams, quizzes (announced or unannounced), and homework assignments. Exams problems will be developed from both lecture and assigned reading materials. All exams will be administered in the regular classroom during regularly scheduled class meeting. 2

INSTRUCTOR POLICIES: • Assignments are structured to give students opportunities to practice and perfect course learning objectives. Working on assignments in groups can be productive and is recommended so long as each member of the group participates as both a learner and teacher • Cellular phones and all other electronic communication devices and/or games are not allowed in the classroom; if carried into the classroom, all such devices must be turned off. • Conduct yourselves as befits professionals in every sense of the word. Be courteous to all, respectful of all, be actively engaged in the class, work hard, be on time, and above all, conduct yourself above reproach at all times. In other words, be a gentleman or lady. ATTENDANCE POLICY: Students are responsible for attending courses for which they are enrolled. They are also responsible for making up any work they may have missed by failing to attend class, even if the absence was approved by the university, necessitated by illness, or necessitated by a personal emergency. In this sense, then, there are no “excused” absences. The instructor is not responsible for providing materials or make up instruction. If a student knows they will be missing class, they should make arrangements to cover their absence ahead of time. Emergencies will be evaluated and addressed on a case by case basis. Information contained in this syllabus, other than the grading and attendance policies, may be subject to change with advance notice, as deemed appropriate by the instructor. 3
