Teaching Methods

Grading and weighing science/Chemistry/Physics / Physical science/Biology grades

Started almost 3 years ago by Hannah Abraham.

Our school admin wants to see uniformity in all science courses weighted the same .Does anybody have suggestions on how Science courses have to be weighted for their final grade? Is 50% tests , 30 % labs and 20 % daily activities sounds reasonable?
Your input would be much appreciated .

    In all of my classes, I do straight points. I used to break it down 30% homework and lab reports 70% tests, quizzes, and projects. Since I went to straight points, it is easier for the school's java-based grading program, and the grades have worked out the same. If I actually look at the points and break them down even more, it is probably about 5% homework, 25% lab reports, 50% tests, 10% quizzes, and 10% projects. I teach at a high school in PA

    Hannah,  When I am teaching Honors or AP,  I use the following percentages: 50% tests / quizzes, 35% for labs, and 15% for homework.  When I first taught regular I did 1/3, 1/3, 1/3.   But the last time I taught regular I believe I did what you are suggesting.
