If I just wanted an answer, I would have asked a computer
If I want a solution, I'll ask a person

A moment of historical ignorance: In 1897, Dr. Edwin Goodwin convinced the Indiana House of Representatives to unanimously pass a bill       which would have effectively pegged the value of Pi at 3.2, 3.23 or 4. Learning even if math is not your best subject, you can still be a smart student the similarities and differences between knowing and not knowing thoughts on grading and learning intuition multi-tasking 1 multi-tasking 2 multi-tasking 3 ADDED JAN 2013 why we make the same mistakes twice [pay attention to the last paragraph] don't put your faith in technology blindly 1 don't put your faith in technology blindly 2 Confidence a photographic metaphor on skill & confidence (click through) does confidence lead to success ADDED JAN 2013 fake confidence helicopters self-compassion, not self-esteem whining Cheating where cheating can get you 1 where cheating can get you 2 ADDED FEB 2013 cheating as a form of personality disorder Math in the Real World math will rock your world how math transforms industries how much math do you need to know marketing is more about analysis (numbers) than creativity nsa: security in numbers Money poor financial decision making & your credit cards

No one cares more about your success than you

  • Items marked (boxed, circled or underlined) in red are the correct answers or steps you needed to show to get credit.
    (You do not automatically earn full credit for correct answers. You must also show correct work.)
  • The number of points for each item is near the marked item.
  • You will pick up your ungraded quizzes on Fri Apr 19.
  • Do your grading in red pen.
    Blue, black, pencil, highlighter etc. are not OK. 3 point service charge for using any of those.
  • Underline the parts of your work that match the marked work on the solution key,
    and next to them, write the number of points you earned on each part.
  • If some step(s) of your work is (are) different from the key, but (you think) still correct, put an asterisk * next to the points for that part, and come to office hours to defend your work and get the credit.
  • Write the number of points you earned for each question in the SCORE: area to the right of that question.
  • Write your total score for the quiz in the SCORE: area on the upper left corner of the front side of the quiz, just beneath the date.
    3 point service charge for not subtotalling or totalling the points.
  • If you have any questions about whether you should earn points for a different method, or for a single algebraic or arithmetic error, you must talk to me no later than Tue Apr 23.
  • Your graded quizzes are due in class on Wed Apr 24. If you do not resubmit the graded quizzes by that date, you will get 0 for the quiz.
  • You may also submit your graded quiz early.
  
  Here is a sample to show you what is required.
  
  
  Math 43 quiz 1 grading sample 1 (Complete)
  
  Notice that in this sample,
  
  
  • They grade in red pen.
    
  • They underline the required parts of their solutions, and write the points next to them.
    
  • Question 1 was graded by me.
    
  • In question 2, they got no intermediate steps correct.
    They decide not to argue for partial credit, and give themselves no credit.
    
  • In question 3, they squared the correct variable (including the vertex shift).
    However, they used the focus instead of the vertex in the other part of the equation, and never found the value of p.
    They decide not to argue for more partial credit, and give themselves only the credit for the one correct part.
    
  • In question 4, they got the second part correct, and put nothing for the first part.
    
  • In question 5, they completed the square correctly, but did not write the equation in the necessary format.
    They also did not identify the vertex, focus nor directrix.
    They decide not to argue for more partial credit, and give themselves only the credit for the one correct part.
    
  • In question 6, they only got the addition and "= 1" part of the equation correct.
    They decide not to argue for more partial credit, and give themselves the credit for only those correct parts.
    
  • They fill in the subtotal for each question, and they fill in the total for the entire quiz.
  
  Here is another sample.
  
  
  Math 43 quiz 1 grading sample 2 (Incomplete - will defend work in office hours)
  
  Notice that in this sample,
  
  
  • They grade in red pen.
    
  • They underline the required parts of their solutions, and write the points next to them.
    
  • Question 1 was graded by me.
    
  • In question 2, they made a sign error early on, which caused many following answers to be wrong.
    However, they did show where those answers came from, and the only errors were all because of the early sign error.
    They feel they should earn partial credit for the correct logic in the later steps, and decide they will defend their work for partial credit.
    They mark those later steps with asterisks (*), and will come see me in office hours no later than Tue Apr 23.
    
  • In question 3, they squared the correct variable (including the vertex shift).
    However, they used the wrong x-coordinate for the vertex in the other part of the equation, and got an incorrect value of p.
    They decide not to argue for more partial credit, and give themselves only the credit for the one correct part.
    
  • They got the both parts of question 4 correct.
    
  • In question 5, they completed the square correctly, but again made a sign error early on, which caused many following answers to be wrong.
    However, they did show where those answers came from, and the only errors were all because of the early sign error.
    They feel they should earn partial credit for the correct logic in the later steps, and decide they will defend their work for partial credit.
    They mark those later steps with asterisks (*), and will come see me in office hours no later than Tue Apr 23.
    
  • They got all parts of question 6 correct.
    
  • They fill in the subtotal for each question except the ones they will defend.
    They will fill in that score after they talk to me in office hours, and then they will fill in the total for the entire quiz.

  Math 1A: Once again, the following handout describes the self grading policy for quizzes.
  
  
  Math 1A self grading policy
  
  Here are the solution keys to use for grading Quiz 1.
  You can tell which version of the quiz you had by the title in the upper left corner.
  The solutions for the calculator portion are below. That part of the quiz was graded by me.
  
  
  Math 1A Quiz 1 Version A Key
  Math 1A Quiz 1 Version B Key
  Math 1A Quiz 1 Version S Key
  Math 1A Quiz 1 Version O Key
  Math 1A Quiz 1 Version L Key
  Math 1A Quiz 1 Version U Key
  Math 1A Quiz 1 Version T Key
  Math 1A Quiz 1 Version E Key
  
  
  • Items marked (boxed, circled or underlined) in red are the correct answers or steps you needed to show to get credit.
    (You do not automatically earn full credit for correct answers. You must also show correct work.)
  • The number of points for each item is near the marked item.
  • You will pick up your ungraded quizzes on Fri Apr 19.
  • Do your grading in red pen.
    Blue, black, pencil, highlighter etc. are not OK. 3 point service charge for using any of those.
  • Underline the parts of your work that match the marked work on the solution key,
    and next to them, write the number of points you earned on each part.
  • If some step(s) of your work is (are) different from the key, but (you think) still correct, put an asterisk * next to the points for that part, and come to office hours to defend your work and get the credit.
  • Write the number of points you earned for each question in the SCORE: area to the right of that question.
  • Write your total score for the quiz in the SCORE: area on the upper left corner of the front side of the quiz, just beneath the date.
    3 point service charge for not subtotalling or totalling the points.
  • If you have any questions about whether you should earn points for a different method, or for a single algebraic or arithmetic error, you must talk to me no later than Tue Apr 23.
  • Your graded quizzes are due in class on Wed Apr 24. If you do not resubmit the graded quizzes by that date, you will get 0 for the quiz.
  • You may also submit your graded quiz early.
  
  Here is a sample to show you what is required.
  
  
  Math 1A quiz 1 grading sample 1 (Complete)
  
  Notice that in this sample,
  
  
  • They grade in red pen.
    
  • They underline the required parts of their solutions, and write the points next to them.
    
  • In question 1, their work is very different from the key (and incorrect), and their answers do not match the key.
    They decide not to argue for partial credit, and give themselves no credit.
    
  • In question 2, their work mostly matches the key, but they are missing one limit.
    They decide not to argue for more partial credit, and give themselves the credit for only the correct statements.
    
  • They got all parts of question 3 correct.
    
  • Question 4 was graded by me.
    
  • In question 5, they have several correct steps, a parenthesis error, and two arithmetic errors (always at the last step).
    They decide not to argue for more partial credit, and give themselves the credit for only the correct steps.
    
  • They fill in the subtotal for each question, and they fill in the total for the entire quiz.
  
  Here is another sample.
  
  
  Math 1A quiz 1 grading sample 2 (Incomplete - will defend work in office hours)
  
  Notice that in this sample,
  
  
  • They grade in red pen.
    
  • They underline the required parts of their solutions, and write the points next to them.
    
  • They got all parts of questions 1 and 2 correct.
    
  • They did no work for question 3.
    
  • Question 4 was graded by me.
    
  • They got all parts of question 5a and 5d incorrect, and their work does not resemble the solution key.
    They decide not to argue for partial credit, and give themselves no credit.
    
  • They got the answer for question 5c correct (although they used an unnecessarily complicated method).
    The credit is based only on the answer for this question, so they give themselves credit for it.
    
  • They got one step and the final answer for question 5b correct, but there is another step which looks different from the solution key.
    They feel this step is equivalent to the solution key, and decide they will defend their work for partial credit.
    They mark that step with an asterisk (*), and will come see me in office hours no later than Tue Apr 23.
    
  • They fill in the subtotal for each question except the one they will defend.
    They will fill in that score after they talk to me in office hours, and then they will fill in the total for the entire quiz.

  Calculus is more theoretical than the other math classes that precede it. There will be a significant emphasis on knowing definitions and theorems in this class. The following handouts will help you understand why, as well as how to interpret certain questions (regarding theorems) that might appear on tests.
  
  
  The difference between definitions and theorems
  Why theorems are important
  The language of theorems
