| V.Evaluation: | |||||||||
| A. TestingProcedures: | |||||||||
| Studentshave a maximum of three attempts to pass each chapter test. If thestudent does not achieve 80% proficiency within three attempts, he/shefails the course. Two attempts will be allowed to achieve 60% proficiencyon the final exam. If a student does not achieve 60% withintwo attempts, he/she fails the course. If a student requires multiple attempts to achieve therequired 80% on the chapter tests, the scores onthe attempts will be averaged. The student will receive the average of the attempts or 80%, whichever is higher. If a student requires a second attempt on the final examto achieve the required 60%, the two attempts willbe averaged. The student will receive the averageof the two attempts or 60%, whichever is higher. | |||||||||
| B. LaboratoryExpectations: None | |||||||||
| C. FieldWork: None | |||||||||
| D. OtherEvaluation Methods: | |||||||||
| Evaluationwill be based on class participation, homework, and projects as outlinedon the syllabus supplement distributed by the instructor. | |||||||||
| E. GradingScale: | |||||||||
| Unlessotherwise stated on the syllabus supplement, the course grade will be theaverage of the individual chapter exams and the final exam. A = 94 - 100 To pass the course, the student must: | |||||||||
| VI.Policies: | |||||||||
| A. AttendancePolicy: | |||||||||
| PellissippiState Technical Community College expects students to attend all scheduledinstructional activities. As a minimum, students in all courses mustbe present for at least 75 percent of their scheduled class and laboratorymeetings in order to receive credit for the course. Students whomiss more than the equivalent of one week of class are not eligible foran I or E grade and are in jeopardy of failing the course. | |||||||||
| B. AcademicDishonesty: | |||||||||
| Academicdishonesty in any form is prohibited and will be dealt with severely. Penalties range from an F or a zero for the specific project or examinationto automatic failure for the course for all students involved. Individual instructors mustdistribute their policy on academic dishonesty during the first week ofclass. | |||||||||
| C. TwoAttempt Rule: | |||||||||
| Accordingto TBR policies, a student must complete this course within two semestersof enrollment or be suspended from all TBR schools for one semester. A final grade of A, B, C, E, F, I, or W counts as one attempt. Withdrawal: | |||||||||
