BIO 215 Spring 2004 Final grades Exam sum : Exams 1 and 2 scores (originally given as %) were multiplied by 1.25 to generate 125 points for each of Dr. Snyder's exams, and were added to Dr. Shortridge's score (150 possible points) to generate 400 total possible points for exams, as given in the syllabus. Lab notebooks : Some sections had notebooks checked once, and some were checked twice. Some were given 20 pts, and some 40 pts. In all cases, these grades were normalized to 40 maximum points, equal to one lab report, as given in the syllabus. Normalizing for differences in TA grading : The mean lab report grade was calculated for each section. Five sections had very similar means and distributions, but the Thursday PM section had comparatively somewhat higher lab report grades. Thus the following procedure was used. Thurs PM students received the sum of their 9 lab reports plus notebook grade for 400 points, exactly what they earned as given in the syllabus. The other five sections had their lowest grade dropped, and the sum of the remaining 9 scores was multiplied by (10/9) to generate 400 possible points. This adjustment gave a fair final overall result without lowering anyone's grade, and is consistent with Dr. S's promise to review possible disparities in grading between different sections. The sum of the exam and report/notebook grades gives a possible maximum of 800 points. The grades are reported below, along with the curve for the course. Since exam 3 grades and lab report 9 scores have been posted for a week, they are no longer subject to appeal. Cutoffs had to be drawn somewhere. Dr. S will not respond to requests to raise grades from students who happen to be slightly below the cutoffs. In general, the Bio 215 grades are very high : a mean of B+.
