Undergraduate TA positions for 2014

I can take a maximum of 4 people as undergraduate TAs for this class next year.

If you will be here for both Winter and Spring quarters of 2014, and you are interested in being an undergraduate TA for this class, please come by and see me. Feel free to call or email me to set up an appointment.

Important things to know are these.

· Class times and the class structure will be the same next year as it is this year.

· Skills for being an undergraduate TA include both understanding the class materials and being able to explain them to others.

· Undergraduate TAs are expected to attend all class lectures, hold their own section, hold 3 hours a week of office hours, grade their section's homework, and help grade exams.

· Although it's a lot of work, being an undergraduate TA has a number of advantages: you learn the materials much better, you develop skill as an instructor, you develop a nice relationship with your fellow TA's and you get a letter of recommendation from me which is useful for your future (plus, at the end of the year, I take everyone out for a celebratory TA dinner).

· Class credit (I believe Psych 497) is available for being an undergraduate TA.

· Please talk to any of the current TAs to get the best sense of what the job is like.

Practice Exams update

· It's been brought to my attention that Practice Exams 2 and 3, allegedly from 2006 are actually from 2004. This is true, but unfortunately, I can't fix the problem, because the actual exams from 2006 have disappeared. I'm sorry for this, but you do still have all exams from 2008, 2009, and 2010, as well as all exams except Exams 2 and 3 from 2006.

Practice Exams for Psychology 318

· Monday's lecture will get into what is traditionally Psychology 318 material (Chapter 10; t-test) and the Psychology 317 Final Exam will cover t-test to some degree. So this seems like as good a time as any to post Psychology 318 practice exams, which you can download from 2006, 2008, 2009, and 2010. You'll find all of them useful next quarter, but Exam 1 will be relevant to this year's Psychology 317 Final. The general organization is the same as it was for the Psychology 317 practice exams.

Also, because you'll be needing it for Monday's lecture, now would be a good time to download the Psychology 318 handout packet from here.

The Final Exam, which will take place on Tuesday, 3/19/13 at 8:30 AM will cover lecture material from all lectures given during the quarter. It will cover the textbook through p. 297, along with Appendixes A-C.

Section assignments are available here. Please make note of your section time, place, and TA. NOTE: Section assignments updated as of 1/8/13 at 6:45 AM

About Section assignments

You will all have been assigned a Section by the UW computer (either an 8:30 section or a 9:30 section that meet on Fridays). However, the UW computer does not do anything about equating the number of students in each section, and in addition, there are actually fewer sections than the UW computer thinks there are; specifically, Sections AE and AG no longer exist. To solve these problems, we will override the UW computer's section assignments and assign you to sections ourselves. Everyone's section assignment will be posted by the second day of the quarter.

More information about homework and homework answers

·Please be sure to staple your homework pages together and circle your answers.

·You can turn in homework to a TA (ideally your TA, but any TA will do)

·You can turn in homework in the Guthrie mail room in the mailbox marked "Psychology 317" with a red label (located sort of to the lower right of the wall facing you as you enter the room ). If you do this, you will discover manila envelopes in that mailbox. Find the one corresponding to your section/TA and put your homework in that envelope.

· There are answers to the odd textbook problems at the end of the book. Many of these answers will be at best incomplete and at worst wrong. Don't get me started on why this is true. After each homework assignment is due, you will receive a full, complete, well-organized, and hopefully correct answer sheet for all the homework problems that have been assigned to you. The first answer sheet, to HW 1, will be posted on 1/10/13, shortly after 12:30 PM

Readings relevant to lecture to be given on 1/14/13

· Chapter 1

Please download these documents. Bring printed versions to the first day of class.

· Class syllabus: Please read carefully before coming to the first class lecture.

· Handout packet: I will constantly be referring to these handouts in lectures.

Readings relevant to lectures 1/9/13

· Chapter 1

Homework #1: Due Thursday, 1/10/13 at 12:30 PM

· Please download HW1 assignment from this Excel workbook. Note that mostly the problems are from the text but, as specified on the workbook, there are some changes to some of the problems.

· Note that HW1 is designed to cover only material that I will have covered in class through the lecture on Wednesday, 1/9/12. Because I will not know exactly what this material will be until class ends on Wednesday, there may be some adjustments to the assignment, which I will post very soon after class on Wednesday.

· This adjustment process will be true of all HW assignments. In general, I try to err on the side of initially assigning more rather than fewer problem on a given HW assignment. This means that any Wednesday after-class adjustments usually entail dropping problems. Dropped problems on any given HW assignment will show up as problems on the subsequent HW assignment.

Greetings!

This site contains information that will be relevant to Psychology 317-318 during Winter and Spring Quarters of 2013 (readings, homework, etc). Please bookmark it and check it at least once per day. Newest information will be at the top of the page, all information will be retained throughout both Winter and Spring quarters.

Should you like to see what happens during the entire 317-318 course, you can access last year's web site here. Note that most of the links will not work, but you can still get an overview of what the course is like.

Emailing questions to me (gloftus@u.washington.edu)

I'd like you to be circumspect in emailing questions to me. If you have a question that needs an urgent answer, then phone me, stop by, or email me. However, if the question can be answered by a TA, then please direct it to your TA or any TA. If the question can wait, ask someone during office hours, or raise the question in section or in class. Thanks.

About Excel

This class will be highly Excel-based in that HW assignments, HW answer sheets, and Exam answer sheets will all be posted in the form of Excel workbooks. It is very, very strongly to your advantage to become proficient in Excel. Knowing Excel will allow you, for example, to do your HW assignments faster by at least a factor of 3. It is possible to do well in the course without learning Excel, but it will be considerably more difficult than if you do learn Excel.
