welcome to winter quarter 2014
(OFFICE HOURS M-F noon-12:50pm in S43)

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 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 fake confidence helicopters self-compassion, not self-esteem whining Cheating where cheating can get you 1 where cheating can get you 2 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 Tue Jan 14.
  • 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,
    underline the work and put an asterisk (*) next to it, 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 Thu Jan 16.
  • Your graded quizzes are due in class on Fri Jan 17.
    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 1B quiz 1 grading sample 1 (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 questions 3 and 5 completely correct, showing all the steps which were required for full credit.
    
  • In question 1a, they showed almost all the required work, but not the bonus step.
    However, they skipped a step in rewriting cosh y in terms of x.
    They feel they should earn the missing credit because all the surrounding steps (which were not assigned points) are present.
    They mark that part with an asterisk (*), and will come see me in office hours no later than Thu Jan 16.
    
  • In question 1b, they had the correct final answer but used a completely different approach which does not resemble the solution key.
    They feel they should earn the missing credit because they think the approach is equally valid, and written correctly.
    They mark that part with an asterisk (*), and will come see me in office hours no later than Thu Jan 16.
    
  • In question 2, they had 2 of the 3 steps correct, but wrote the middle step in English rather than proper mathematical notation.
    They feel they should earn partial credit for the correct reasoning.
    They mark that part with an asterisk (*), and will come see me in office hours no later than Thu Jan 16.
    
  • In question 4, they showed almost all the required work, but skipped a required step in the simplification of the quadratic formula.
    They feel they should earn the missing credit because all the surrounding steps (which were not assigned points) are present.
    They mark that part with an asterisk (*), and will come see me in office hours no later than Thu Jan 16.
    
  • 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.
  
  Here is another sample.
  
  
  Math 1B quiz 1 grading sample 2 (Complete - will not 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 questions 2, 4 and 5 completely correct, showing all the steps which were required for full credit.
    
  • In question 1, they showed almost all the required work, including the bonus step.
    However, they skipped a step in rewriting cosh y in terms of x.
    They decide not to argue for partial credit, and give themselves credit only for the correct parts.
    
  • In question 3, they are missing the values of sech x and cosh x.
    They decide not to argue for partial credit, and give themselves credit only for the correct parts.
    
  • They fill in the subtotal for each question, and they fill in the total for the entire quiz.
    
  • In reality, they showed alternate but appropriate work for questions 1 and 3,
    and should have defended their work for the remaining partial credit.
