  • Don't forget to add 'NATS 104' to the subject line when you email us.

  • The GTA's are having a hard time reading some students' homework. From now on, neatness, spelling, and grammar count toward the grade. For your Experimental report, due at the beginning of class, Friday, we strongly suggest that you hand in a typed report.

    Another "cheating" incident
    Peer review scrutiny

    1/24/06



  • The reading assignments are now correct to the chapter number. When I get a copy of the 6th edition, I'll shorten the readings to sections of chapters.

    There was some confusion regarding the workshops instructions. Some students were following last years assignments. I have deleted all those old files.

    There will be a 10 point quiz on Friday. This is a 50 minute long exercise. Your score for this quiz will depend on how well you follow instructions, unlike other quizzes which will be based on your understanding of the readings and lectures.

    1/31/06



    Graded Homework
    The GTA's will try to return your homework after class, Monday or Wednesday after it was due. Friday, the third homework will be delayed until next Wednesday, to make time for Friday's quiz.

    FIRST MID-SEMESTER EXAM TODAY
    Good luck!
    Bring pencils and erasers!
    No Calculators!

    2/20/06



    FIRST MID-SEMESTER EXAM RESULTS
    The average scores was 70%. There were
      14 - As
      38 - Bs
      51 - Cs
      41 - Ds
      The average total current grade is a few points lower, because some students started after the first week, have missed quizzes, or have not turned in workshops.
      If you got less than a "C" on the exam you should schedule a meeting, in advance, with one of the TAs to go over the exam. They have to retrieve the exam first, which will take a while.
      If you have already given a TA permission to send your grades you can get them by email, and schedule the meeting.
      Otherwise you will have to visit your TA, get the grade, and then schedule the meeting.
      Students who are doing very poorly are being referred to UA academic advisors.

    TERM PAPER
    1. There was a mistake on the instructions for the term paper. The number of points for the paper was wrong. It is worth 30 points, as is written in the syllabus, not 20 points.
        We have replaced the number of points on the rtf and pdf files.
    2. On Monday (2:00), hand in pages 5 and 6 for 10 points (this has not changed).
    3. Your term paper first draft, plus the peer review sheet will be turned in on April 21. The TAs will redistribute your paper to it's reviewer, who will complete the review and return it to you before the end of the period.
    4. The following week, April 28, you will submit your revised paper (30 points), incorporating the reviewer's comments, at the beginning of class plus
        The reviewr's page p.8 (10 points for the reviewr)
        Your self-review p.9 (10 points for you)
    YOUR CURRENT GRADE
    • The list of grades for exam 1 (see archive) Did not include "Es"
    • If you received less than 60% ("E") on exam 1 you must make an appointment with Chris or Steph to go over your test before Spring Break. If your class grade is well below an "E" you have been referredto a UA advisor through successnet.arizona.edu/
    • To get your grades you either have to visit Steph or Chris, or give them written permission to send your grade by email
    "NATS 104" in the Subject Line
    • Chris and Steph (and Prof. Davis) are not responsible for emails that are sent to them without "NATS104" in the subject line. Without that in the subject line they are too easy to miss or delete as spam.
    • The GTA's are having a hard time grading some student's homework. To receive full credit, your homework
        1. must be legible, neat and spelled correctly
        2. must be stapled if more than one page long (otherwise pages get lost)
        3. must be on a whole page of paper, not a piece

    QUIZZES
      There was some confusion expressed regarding the fourth quiz. Please read the Syllabus. I announced the date of the first quiz as a one-time favor. But, that was an exception. The remaining five quizzes will be un-announced.
    HOMEWORK
      Note that there will be at least 6 quizzes. The quizzes can cover lecture material, assigned readings, or the workshops. We encourage you to start the workshops as soon as you can and contact your TA or Prof. Davis with any questions regarding the homework.
    02/05/06



    HOMEWORK
      Workshop 8 is due at the beginning of class, Friday.
    HOMEWORK RESPONSIBILITY

    Please read the Syllabus regarding handing in materials. They are due to the GTAs at the time and place specified. The GTAs may, under exceptional circumstances, accept the homework by email or by other means, but this should be a rare privilege, the GTAs are under no obligation to make such exceptions. If a student leaves an email in a mailbox or shoves it under a door, without written permission, the GTAs are under no obligation to grade that homework.

    SPRING BREAK WORKSHOP
      By popular demand, we are offering an optional workshop for Spring Break. Those who complete this workshop will not be eligible to receive credit for the March 24 exercise (to be announced). This will be due noon, Wednesday, March 22, 2006. rtf pdf
    02/09/06



    TEST PREPARATION HOMEWORK

    EXAM 2
    The average score for the second exam was a couple of points higher than for the first 100 point exam - "C". This is good news, because this material was new to most of you, whereas the first exam was largely review for most of you. Congratulations.
