Instructional supplements, such as text specific lecture notes, homework assignments, sample exam questions, and other course related information, are periodically posted online. Students are strongly advised to use these tools regularly to enhance their ability to succeed in the course. Instructor/Program Requirements Attendance Policy Regular attendance is required. Students are expected to attend the entire class, i.e. lecture and laboratory portions, regularly. Class attendance is checked every session.

6 It is the responsibility of each student to amend his or her professional/personal schedule to meet the class schedule. If the student is going to be absent for any reason, he or she should arrange to get the notes and information from a fellow classmate. Students are responsible for completing assignments scheduled during their absences. As stated in the HCCS Student Handbook, a student may be dropped from the course if the student s accumulated absences are in excess of 12.5% of the hours of instruction. Therefore if a student is absent more than three times, he/she can be dropped from the class. The instructor has the full authority to drop a student for excessive absences; however, it is the responsibility of the student to drop a course. If a student just stops coming to the class and does not drop the course, he/she will get an FX in the class. Tardiness: Students are expected to be on time for each session. If a student is frequently late for the class, he or she may be marked absent for the many sessions he or she has been late. Tardiness will be marked in the attendance record. inquiry: Students must use their HCC account and/or Eagle Online when communicating with the instructor. Questions via will be answered within 48 hours or in the next class meeting depending on the nature of the question. Course Grading Policy Lecture Grade There will be three (3) regular lecture exams, three (3) bonus quizzes and one (1) final lecture exam. The exams will be over the materials covered in class. Students have one hour and half to complete each lecture exam and ten to fifteen minutes to complete each bonus quiz. The final exam is comprehensive and departmental. Students have two hours to complete the final exam. There will be no breaks during any of the exams or quizzes and, if any student leaves the room for any reason, that student should turn in his/her exam/quiz. The student will not be allowed to continue taking that exam. Each homework assignment will count as one (1) added bonus point toward the final exam grade. Laboratory Grade There will be laboratory experiments, reports and assignments. Students need to submit a lab report for every experiment performed in the lab the following lab period. Late lab reports and assignments will be penalized and/or will not be accepted. Each experiment will be graded based on (1). Lab attendance and performance, (2). In-Lab report, and (3). Pre- and Post-lab review exercises. Students are expected to comply with all the laboratory rules and safety instructions. Safety glasses or goggles must be worn at all times during the

7 laboratory experiment period. Any student not wearing glasses or goggles after the experiment has begun may be given a zero for that experiment! Make-up Policy There will be no make-up for any lecture examination/laboratory experiment. Failure to take a lecture exam or perform a lab experiment will result in a zero (0) for the missed exam/experiment. It is mandatory to take the final exam, and no student can be exempted. A student who completes the course by taking the final exam cannot receive a W in the course. Grade determination There will be three (3) lecture exams worth 100 points each. There will be three (3) quizzes worth 10 or more added bonus points each. The lab experiments, reports and assignments are worth 150 points. The final exam will be worth 120 points. If the final exam grade is greater than the lowest lecture exam grade, the final exam grade will replace the lowest exam grade in computing the overall grade. Total points to be earned in this class = 600 points Points earned by the student The overall score = x 100 Total points The overall score is based on the following: Three lecture exams 55% Laboratory 25% Final exam 20% The course grade is then obtained from the overall score: A = % B = % C = % D = % F = 0-59 % HCC Grading Scale The HCC grading scale is: A = : 4 points per semester hour B = 89 80:.3 points per semester hour C = 79 70:.2 points per semester hour D = 69 60:.1 point per semester hour 59 and below = F..0 points per semester hour IP (In Progress) 0 points per semester hour W (Withdrawn).0 points per semester hour

8 I (Incomplete)...0 points per semester hour AUD (Audit) 0 points per semester hour IP (In Progress) is given only in certain developmental courses. The student must reenroll to receive credit. COM (Completed) is given in non-credit and continuing education courses. To compute grade point average (GPA), divide the total grade points by the total number of semester hours attempted. The grades IP, COM and I do not affect GPA. Classroom Policy Learning Environment Students are expected to engage in the learning environment (i.e. listen to the lectures, participate in discussions, read the topics covered and do the assignments).
