Ah, so that might be an important difference. Students will have 9-12 hours of homework per week in my class.
Something else to keep in mind are these classes of activity that are more about pushing information vs. development of knowledge. Colleges weigh these things differently, which calculates into what the load of a course is - and how much education it would be, quantitatively.
First, some math:
Credit hours calculate the type of activity ratio, multiplied by the number of hours performing it, and dividing that by 30
Quarter Credits calculate the type of activity ratio, multiplied by the number of hours performing it, and dividing that by 45
1) Didactic - Things like lecture that are 100% one way pushes of information transfer (2.0)
2) Supervised Lab - Lab work that is under the direct management of an instructor (1.5)
3) Externship - Work that is performed in a professional environment (1.0)
4) Unsupervised Lab/Outside Work - Work that is done by the student with little to no input from the instructor. (0.5)
So if we take a class that met three times per week, twice for a two hour lecture, once for a one hour lab, for 16 weeks.
Lecture: 2hrs x 2 per week by 2.0 ratio = 8 - multiply that by 16 = 128
Lab: 1hr x 1 per week by 1.5 ratio = 1.5 - multiply by 16 = 24.
128+24 = 152/30 = about 5 Credit Hours for that course.
Meanwhile, if you had one 2hr lecture and two 1hr labs:
Lecture 1x2x2 = 4 -> 4x16 = 64
Lab 2x1x1.5 = 3 -> 3x16 = 48
48+64 = 112 -> 112/30 = 3.73
All that to say that how you arrange the course, at least according to the Carnegie system, would factor how accreditors would estimate the actual load of a course. While you can't quantify this on a student level, since every student is different, it generally holds true. One would expect, then, in the heavier class, a student would gain more knowledge.
And I didn't even factor homework, but you can figure that bit out - or just put the numbers in Excel and go to town.
