Course Syllabus—Dual Credit General Biology 1 Laboratory Course Title/Course #: General Biology I Laboratory (BIO 1131) Dates of Course: August 6, 2015 – December 10, 2015 Instructor: Ms. Emily Bethea e-mail Address: emily.bethea@rcsd.ms Textbook: Pendarvis, M. and Crawley, J., Exploring Biology in the Laboratory Morton Publishing Company. 2nd edition Course/Departmental Grading Scale: A=90-100 B=80-89 C=70-79 D=60-69 F= Below 60 Methods of Evaluation: PLEASE READ CAREFULLY!!! The laboratory is a completely separate college course from the lecture, and students will receive a separate grade. Students will participate in ten labs throughout the semester. Students will answer questions assigned in the lab book. Students will also have three lab practicals throughout the semester. Completing the questions and participating in lab will count for 10% of the grade. The average of the lab practicals will count for 90% of the grade. In the high school grading, the lab is not a separate course. Whatever your college lab grade is, that number will count for 25% of your high school grade, and the lecture will count 75%. The final number will be weighted by 1.10.
