Two recent incidents in Intermediate Algebra (high school Algebra II) help explain the low pass rates of students.
In the first case the student was trying. He was supposed to be working on an online assignment which involved factoring of trinomials. I saw he had another screen up and asked him about it. He said he was working, which was true. He Googled the factors of 45.
In the second case, the student arrived fifteen minutes late to a computer classroom, where beverages are not allowed, carrying a cup of Starbucks coffee. When I reminded him of the rule, he put his coffee cup next to the wastebasket. I threw it away after he left without it. This would not be a particularly significant incident except the fifteen minutes he missed of class was from a test which was 16% of his grade.
These two incidents display the major reasons students don’t pass, lack of prerequisite knowledge and lack of commitment.
