2/22 Algebra 1 - Test Results and Exponent Rules

We took our Chapter 7 Test last class period and here are some results.

3rd period:
16 of 18 answered both the first two questions correctly, knowing what a solution to a system of equations is.

12 of 18 solved at least the first (easiest) substitution method problem correctly. That translates into 67% meeting or exceeding the standard on that method.

Again, 12 of 18 solved at least the first (easiest) combination method problem correctly. 67% meeting or exceeding the standard for that method.

16 of 18 students solved at least one system of inequalities graph correctly. That is 89% of students who grasp the concept on its most basic level.

I would like to see numbers around the 70% range for students who can correctly solve the first problem of each concept. This demonstrates at least basic knowledge of the method.


4th period:
Only 9 of 19 got the first concept, knowing the solution to a system, perfect. But the remaining 10 got one of the two right, so all 19 of us did at least "average" or "C" work there.

10 of 19 solved at least the easiest substitution problem correctly, while 4 others did partially correct work on a few of the 4 problems. That makes 73% with basic knowledge of the process.

15 of 19 got at least the first combination problem correct, giving a 79% figure for students with a basic understanding of the process.

All 19 got at least 1 graph correct, meaning 100% of us "understood", at least on the most basic level, what the solution of a system of inequalities should be and how to get it.


I had the students who did not get at least the first two problems of each section on the test work on those problems to boost their knowledge a little bit. Test grades will remain, but I want them to have a little better grasp on the idea before moving on.



After that, the students took notes over the first section of the new chapter, explaining the exponent rules for multiplication. We went through a few additional examples together as well. The video above shows some of what the students will be doing with exponents.
