I have an issue I hope someone will be able shed some light. I received a letter from ds's school yesterday informing me that ds had to receive a particular grade in two different subjects or he will have to repeat the grade (he actually only has to pass one to be promoted). In math he will have to raise the grade 25 points.
The problem I'm having is how his math teacher determines her grades. Instead of the traditional percentage, getting 40 right out of 50 yields 80%, she gives each individual problem a value of 1 point and does the percentage at the end of the 9 weeks. The problem with this is when an assignment has more than 100 questions or the students start getting problems wrong.
For example, some of the grades are as follows....
Worksheet.......41/74
Test...............79/100
Worksheet.......36/42
Worksheet.......44/53
Worksheet (multiple)..100/239
Total: 300/508 = 59% F
I think it should be...
Worksheet.......41/74 = 55.4% F
Test...............79/100 = 79% C
Worksheet.......36/42 = 85.7% B
Worksheet.......44/53 = 83% C
Worksheet (multiple)..100/239 41.8% F
Total: 68.98% F
He would still have to recoupe but it would be possible. I've done the math and if he were to have the same amount of assignments for the remainder of the quarter and were to ace every single one of them, he could only raise his score 23 points...resulting in being retained. Test are worth the same as homework in this system. A bad day will bring down 3 good ones. Nothing is graded alone and then averaged together....it's all one big assignment and the student is graded accordingly.
I have attempted to explain this to the principal and math teacher and they don't understand the math. I tried to explain that someone gets 74 out of 74 they don't make a 74!!!! They make a 100% because each problem is worth 1.35 points each!!! They're reply was..."yes, that's right and that's what we did". No it's not because if I get 239 out of 239 I don't make a 239
% I make a 100% because they're worth .4 points each yet they graded EVERYTHING as one point!!!! They looked at me like I was crazy and told me they would be happy to have an official meeting next week to discuss this matter.
Anybody know how I could convey this math so the math teacher will understand???? Has anyone else dealt with this way of grading? I'm pacing the floor it's worrying me so bad.
