1 Welcome to Biology 1A, UC Berkeley, Summer 2004 Introduction: Hopefully you will find Biology 1A to be a fun and exciting class. It will be readily apparent to you that the lecturers, graduate students, and staff enjoy biology and teaching! Warning - the pace will be blistering fast. You are expected to have a good understanding of chemistry examine the chemistry review sheet on page 6. The class consists of four lectures, two labs and two discussions each week. All students must fill out the form on page 7. Use this form to add/switch AND create a password. Even if you are not switching or adding you must fill out this form to select a password. Turn it in after lecture or place it in the mailbox outside of 2088 VLSB, by 5 PM on June 21. Attendance: You are expected to attend ALL lectures, discussions, etc. Communication: Office hours are held in 2084 or 2088 VLSB. Messages for lecturers, Mike Meighan, and the GSI's may be left at addresses are on page 4. Lectures and Lecturers: The lecturers are Dr. Jim Baxter (6/21-7/15) and Professor Neeraj Chugh (7/20-8/11). Dr. Steve Takata will give one lecture on July 20. Lectures are held M. - Th. from 12:30 PM to 2:00 PM in 1 Pimentel. Lectures are not webcast. Black lightning note-taking is authorized to take notes. Office hours: Office hours are held in 2084 (or 2088 VLSB). See page 4 for a list of office hours. Please come to any office hour lecturer s, GSI s, or Mike s. GSI s: The GSI s will teach labs and discussion. Each will hold one office hour per week. Labs and Discussion: Labs and discussion meet twice a week and are required. You must fill out the form on page 7. Turn it in after lecture or place it in the mailbox outside of 2088 VLSB, by 5 PM on June 21. Further lab information is provided. Mike Meighan will handle section changes and adding. Repeating Students: Students repeating the class may not have to repeat the lab if they scored above the lab mean (when they took the class). If interested, fill out the form outside of 2088 VLSB by 5 PM today. Eligible students will be contacted (by phone/ ). Study Advice: Read the material before lecture! At a minimum read the first page and last two pages of assigned chapters. During lecture take notes and pay attention. Refer to the lab manual for further information on studying. The Student Learning Center will be offering study groups on M/W from 10 AM to Noon and on T/Th 9-11 AM. There will also be drop in hours. GRADING PROCEDURE: Letter grades will be determined from numerical scores as follows: Midterm Examinations (2 x 150) (each lecture is worth about 15 points) Laboratory & Discussion: Lab Exam # 1, 7/26, in lecture (Labs 1-7) Lab Exam # 2, 8/9 or 10, during your lab period (Labs 8-12) Quizzes - In discussion or lab (12 labs x 3 pts minus the lowest quiz scores) Final Exam (held on 8/12) Total A or A or A % C or C or C % F 59-00% B or B or B % D or D or D % 300 pt s 90 pt s 75 pt s 33 pt s 105 pt's 603 pt s Page 1 of 7.

2 Grades are typically curved. Minimum grades as listed above are guaranteed. The total % needed for some form of an A, B, C, or D may be lowered depending upon the final distribution of students scores, i.e. we curve the class if need be. GRADING PROCEDURE: In the event that some examinations have been unusually difficult, the cut-offs for letter grades may be lowered (but only by a few percentage points, and only as deemed necessary). Historically around 50% of the class EARN A s and B s. Grades are based upon total points which includes your lab and lecture points. Some adjustments are made to lab exam 2 grades and quiz grades to adjust for differences between the various sections. How is this done equitably? A linear regression analysis is used to adjust grades. The mean for lab exam 1 is determined for each section and those values are used for the X axis. The mean of lab exam 2 (or quiz scores) are the values used for the Y axis. A best fit line is generated. Each section is then adjusted UP to the easiest/highest of all of the sections (maintaining the same slope but modifying the intercept which adjusts for the easiest/highest section). Then adjustment points are added for each student within a section. Thus no students are penalized (for being in a hard section) and no students have an advantage (for being in a easy section). See below for a graphical representation of these adjustments. Quiz scores by section Easiest grader line Average Grader Line Lab Exam 2 scores by section Easiest grader line Average Grader Line Lab Exam 1 Points (by Lab Exam 1 Points (by sect.) sect.) Average lab exam 1 scores, quiz scores, and lab exam 2 scores are determined for each section/pairing (2 sections take the same lab exam 2). Lab exam 1 averages are used for the X axis and quiz scores (or lab exam 2) for the Y axis. A best fit line is generated. The slope of this line is kept and is brought UP TO THE :EASIEST/HIGHEST" average. This is repeated for lab exam 2 (Y axis). The total points is then determined for each student. We look at 90% of the points in the class and see what % of the students earned a guaranteed A/A/A-. If there are fewer than about 20% of the students we then typically lower the number of points required for some form of an A (since it is the lower end it would be A-). We continue to do that for each guaranteed grade range, B, C and D. If need be, we lower the total number of points necessary to get a certain grade. We usually give out about 20% A s, 30% B s, 20% C s, 10% D s and 10% F s. We then go back and make the exact cutoffs for each form of a grade (eg. C, C, C-). We then look to see if students are within 5 points of the next highest grade. If so we need to determine if they should be bumped to the next higher grade. The most important criteria for this bump in the summer is attendance and participation in lecture/lab/discussion (pre-labs/worksheet averages). We only consider bumps if the students are within 5 points. On average about 50% of the students who are within 5 points get bumped, 50% do not. Note that the class is, in a sense, curved. But we would rather that you strive to reach the 90 percentile, instead of us having to lower the percentage cutoffs for given grades. Page 2 of 7.

3 Lect ure: Lecture exams will be taken in class. The midterms are scheduled for J uly 12 (lectures 1-10 or 11 = 150 pts,) and Aug. 2 (lectures 11 (10) -14 = about 60 pts, lectures = about 90 pts). The final is scheduled for August 12 (lectures 21-27, 105 points). Exam Format: Exams will contain both multiple-choice questions and short answer, essay or fill in the blank questions. 150 point exams will have about 100 points multiple choice and 50 points that will be short answer, essay or fill in the blank. The final will be 85 points multiple choice and 35 points short answer, essay or fill in the blank. Lab exam 1 will have about 35 pts multiple choice and 55 pts short answer. Lab exam 2 will be almost exclusively short answer. There will be NO make-up exams. If you miss an exam due to illness, you must present a written, verifiable medical excuse. Your exam will be calculated on a pro-rated score. Lab: Daily lab quizzes worth a total of 33 pts (12 X 3 pts minus the lowest score) will be given at the start of each lab. Pre-labs are required in order to do lab. Worksheets are also required. Lab exam 1 worth 90 points will be held in lecture on July 26. It will cover labs 1-7. Lab exam 2, worth 75 pts, covers labs 8 12 and will be given in your lab, either Aug. 9 or 10th.
