BHCC MAT-092 Common Midterm Exam Grading Rubric 3/3/11

Each problem on the midterm exam will receive a point value according to the criteria below:

5 points: Full use of appropriate procedures, 100% correct answer

4 points: Full use of appropriate procedures, but a very slight error is made that prevents student from reaching the correct answer

3 points: Partial use of appropriate procedures; incorrect answer given; student is unable to carry out a procedure completely, but more than 50% of work is correct

2 points: Minimal use of appropriate procedures; incorrect or missing answer; student’s work is less than 50% correct

1 point: Lacks use of appropriate procedures; incorrect answer; student misinterprets problem

0 points: Problem is left blank; no attempt is made to solve the problem

1 / blank / Student provides a response, but does not write the ratio as a fraction / Student writes the ratio as a fraction, but does not attempt to reduce it / Student writes the ratio as a fraction, and reduces it, but not completely / - / Student writes the ratio as a fraction in simplest form
2 / Blank / Not left blank, but response demonstrates no understanding of how to solve a proportion / - / Student sets up problem correctly (e.g., shows cross product equation), but subsequently does not follow correct procedure / Student sets up problem correctly, and proceeds to solve by a correct process, but a slight arithmetic error results in incorrect answer / Student provides the correct solution
Question / 0 points / 1 point / 2 points / 3 points / 4 points / 5 points
3a,b / Both parts blank / Neither part left blank, but responses demonstrates no understanding of “proportion” or how to correctly solve a proportion / Student responses demonstrate some understanding of “proportion” but work is less than 50% correct (e.g., a proportion is given, but student does not follow a correct procedure to solve it / - / Student gives the correct proportion (part ‘a’ correct), and follows an acceptable procedure, but a slight arithmetic error results in an incorrect answer for part ‘b’ / Both parts correct
4a,b / blank / Not left blank, but incorrect answers for both parts (including a non-equivalent fraction in part ‘b’) / Answer to part (a) is incorrect, but an equivalent, but unsimplified, fraction answer to part (b) is given
-or-
Part (a) is correct, but no equivalent fraction is given in part (b) / Student response to part (a) is correct, but an unsimplified fraction is given in part (b) / - / 100% correct answers
5a,b / blank / Not left blank, but incorrect answers for both parts / Correct answer is given for either part (a) or part (b), but not both parts / - / - / 100% correct answers
6 / blank / Not left blank, but demonstrates no understanding of how solve problem / - / Student sets up problem correctly, but obtains incorrect answer / - / 100% correct answer
Question / 0 points / 1 point / 2 points / 3 points / 4 points / 5 points
7 / blank / Not left blank, but demonstrates no understanding of how to set up a proportion / Student sets up a proportion, but some numbers are misplaced /
- / - / 100% correct answer
8 / blank / Not left blank, but demonstrates no understanding of how to solve the problem / - / Student sets up problem correctly, but does not demonstrate knowledge of how to solve it / Student sets up problem correctly and shows knowledge of how to solve it, but a slight error produces an incorrect answer / 100% correct answer
9 / blank / Not left blank, but demonstrates no understanding of how to solve the problem / - / Student sets up problem correctly, but does not demonstrate knowledge of how to solve it / Student sets up problem correctly and shows knowledge of how to solve it, but a slight error produces an incorrect answer / 100% correct answer
10 / blank / Not left blank, but demonstrates no understanding of how to solve the problem / - / Student correctly sets up the problem, but does not solve it correctly (work is more than 50% correct) / Student sets up problem correctly and shows knowledge of how to solve it, but a slight error produces an incorrect answer / 100% correct answer
11 / blank / Not left blank, but demonstrates no understanding of how to solve the problem / - / Student correctly sets up the problem, but does not solve it correctly / Student sets up problem correctly and shows knowledge of how to solve it, but a slight error produces an incorrect answer / 100% correct answer
Question / 0 points / 1 point / 2 points / 3 points / 4 points / 5 points
12a,b,c,d / At least 3 parts left blank / At least 2 parts are answered, but incorrectly / Correct answers are provided for at least 2 parts, and other parts are not left blank / Correct answers are provided for 3 out of 4 parts / - / All answers are correct
13a,b,c / At least 2 parts left blank / 0 out of 3 parts are answered correctly, but no more than 1 is left blank / 1 out of 3 parts are answered correctly / 2 out of 3 parts are answered correctly / - / All answers are correct
14 / At least 3 parts left blank / At least 2 parts are answered, but incorrectly / Correct answers are provided for at least 2 parts, and other parts are not left blank / Correct answers are provided for at least 3 parts, and other parts are not left blank / - / All answers are correct
15 / At least 2 parts left blank / 0 out of 3 parts are answered correctly, but no more than 1 is left blank / 1 out of 3 parts are answered correctly / 2 out of 3 parts are answered correctly / - / All answers are correct
16 / blank / Not left blank, but answer is incorrect / - / - / - /
Correct answer given
17 / blank / Not left blank, but answer is incorrect / - / - / - / Correct answer given
18 / blank / Not left blank, but no knowledge of how to solve the problem is demonstrated / Student attempts to use an incorrect formula to solve the problem / Student uses correct formula but obtains incorrect answer / Student correctly solves problem, but does not correctly round to nearest tenth / 100% correct answer
Question / 0 points / 1 point / 2 points / 3 points / 4 points / 5 points
19 / blank / Not left blank, but no knowledge of how to correctly set up problem is demonstrated / Student sets up problem correctly, but makes major errors in finding the total height of the boxes (overall work is less than 50% correct) / Student sets up problem correctly but a slight error is made in finding the total height of the boxes (work more than 50% correct) / Student provides correct height of boxes, but does not use a number smaller than 12 for the inches / 100% correct answer
20 / blank / Not left blank, but student demonstrates no knowledge of how to correctly begin solving the problem / Student attempts to convert g to kg, but does not do so correctly, and does not attempt to add the measurements / Student converts g to kg and adds the measurements, but makes more than one error in doing so / Student converts g to kg, and adds the measurements, but makes a single slight error producing an incorrect answer
-or-
Student gives correct answer in g instead of kg / 100% correct answer
