These were the Course Policies for PSY 101 the last time I taught it in the Spring of 2002:

TEACHING PHILOSOPHY
I love to teach and I work very hard at it. While I hope the class will not be dull and boring, I do not think teaching should be confused with entertainment. Sometimes I think that some students' expectations are that classes will be as entertaining as television. There are several reasons why this is not likely to happen. An hour of television costs hundreds of thousands of dollars. We do not have that level of funding to put on an hour of class. More importantly, the producers of television generally do not care if you learn anything or not. They want to you to buy something because they have packaged you up and sold you to their sponsors. That is what television does, it sells you to the highest bidder.

In contrast I want you to learn something, and that is about all I want. Of course I would like it if you were happy and excited all the time, but I can not guarantee that. Your mood is basically up to you. As far as I am concerned, you have learned something from the class if (1.) you see the world differently than you did before class and (2.) if you can do some things that you could not do before class. The first of these is a cognitive goal and the second is a behavioral goal. I will try very hard to teach you but I can not make you learn. However, I believe that you will learn if you work as hard at learning as I work at teaching.

GOAL
The goal of this course is to introduce you to representative areas of psychology and to teach you to think like a psychologist. Your reading will consist of contemporary research studies. In this course, psychology will be treated as an empirical science. My goal is to help you develop an understanding of research methods and their outcomes. You will not be working with the usual type of textbook because these books do not give you the tools that you need in order to evaluate information about behavior. Textbooks often focus on examples of outcomes of psychological studies. In doing so, the excitement and adventure of psychological investigation is lost. In contrast to the usual textbook-based course, I propose to include considerable coverage of the way in which new information is discovered. I am one of the authors of the textbook you will use in this class. More about the book and the teaching philosophy behind it can be found elsewhere on my website.

Having you use my book as a text is not part of some money making scam for me. I wrote this book with a colleague, Matt Merrens. We wrote it because we wanted a book with a different approach than was available from texts already on the market. I sincerely doubt that we will ever even earn the minimum wage for all the hours that we spent writing this book. If you want to get rich, go work in a grocery store--do not write a college text.

ATTENDANCE
Attendance will be taken in this class. Falsification of any signature on the attendance sheet will be dealt with in accordance with the college policy on academic dishonesty as found in the college catalog and in a section below. Different sections of PSY 101 are not interchangeable: you must attend the one in which you are registered. You will not be permitted to participate or take exams in other sections meeting at other times. It is your responsibility to sign the attendance sheet. If, for any reason, you do not sign it as it is being passed around in class, you must take the initiative to come up and sign it at the end of class in order to avoid being considered absent.
To be successful in this course you need to attend class meetings and arrive on time. Except in emergencies, it is impolite and unprofessional to arrive late or to get up and leave during the class meeting without having previously discussed your departure with me.

You are responsible for all material presented, handouts, announcements, and changes in scheduling which are made whether you are in class or not. Class WILL be held on days adjacent to holidays so please arrange your holiday transportation accordingly. I assume that I am dealing with serious students who plan to be where they are supposed to be every day.

In the event of weather emergencies you can find out if the college is closed by calling the college class weather line at 564-CLAS. In that event, I will email you on your college email telling you what adjustment we will make in the reading assignment schedule.

PARTICIPATION
A significant part of your grade will involve the evaluation of the quality of the remarks that you make during class discussions. I will frequently call on you, by name, to ask you questions about the assigned reading and other course material. I will grade your answer on the spot and your total performance at this activity will become your participation grade. In order to get credit for your participation you will have to have a sign, with your last name clearly written on it, in front of you. I will supply the materials for name signs. You will also have to speak loudly enough to be heard by the entire class in order to get credit. You are addressing the entire class, not just the instructor. Speaking to a group is a valuable life skill. If you plan to refuse to answer questions in class or to persist in answering so softly that you cannot be heard, then this is not the class for you.

Former students have considered the participation requirement to be a valuable teaching tactic. This is an opportunity for you to sharpen your oral presentation skills as well as your ability to think on your feet. You will have to attend class and to be ready to answer questions. The third time in a row that I call on a student who is either absent or has no answer whatsoever, I will cease tyring to call on that person. He or she will lose the credit available for participation. It is possible to pass the course with a zero for participation, but it is difficult to get a very good grade without participation. The reason for this policy is that I refuse to waste the time of students who are prepared and who are present while I am calling names and waiting for those who are not. As you will see, the questions that I ask can reasonably be answered by anyone who has read and understood the daily assignments. If there is something that you do not understand in the reading, you can prevent being called upon to discuss it by raising your hand and asking a question about it in class. I plan to ask you many questions and I certainly do not object if you ask me questions.

SEATING
You should not sit behind the row that is designated to be the back row of the theatre except on exam days. Later in the semester, the designated back row may be changed if the numbers attending class dwindle. The reason why you should not sit elsewhere is because it can be difficult for your answers to be heard if you sit way in the back of the room. It can also be difficult for you to hear answers from other students. Each day that you sit behind the designated back row your course grade will be lowered by 1%. You should not come in late, but if this happens, you should not use tardiness as a reason to sit beyond the designated areas.

EXAMINATIONS
There will be four hour exams in this course which will assess your understanding of material in the course. They will consist of 50 multiple choice questions each. These exams will not be offered at any time other than the time for which they are scheduled. There will also be a comprehensive final exam during exam week. The final examination is required, not optional. In addition to counting as an exam score, the score (% correct) you obtain on the final exam will be used to replace the 0% on any regular exams you missed. The final exam can be used to replace any number of missed hour exams, from one to all four. I strongly advise all students to prepare for and to take each of the regular hour exams but, if emergencies arise and this is not possible, the final exam will serve as the make up. Students arriving more than 15 minutes late on an exam day will not be admitted to the room and will receive a score of zero for that exam. You are responsible for bringing number two pencils and an eraser to exams. If your name, last name first, is not coded by coloring in the dots on the back of the answer sheet, the score on that exam will be reduced by 5%.

HOMEWORK

The reading assignments for the semester will be from the textbook: Shaffer, L & Merrens, M. R. (2001) Research Stories for General Psychology, Needham Heights, MA: Allyn & Bacon. All of the assignments and exam days are being given to you today on a separate sheet so that you can plan your life acordingly.

There is also written homework due every day that class meets-- except for exam days and the last day of class.
Your written homework must be handed in by being placed in the appropriate alphabetic pile on the table in front of the classroom before class begins--not thirty seconds later, not even two seconds later--on the day the assignment is due. Late homework, regardless of the reason, receives no credit. If you join the class after the initial days of the semester you will not be allowed to turn in past due homework for credit. If you know in advance that you are not going to be in class, you may hand your homework in early by placing it in the appropriate pile on a day before it is due. Owing to the large number of students in the class and the potential for bookkeeping errors on grade entry, I can not accept emailed or faxed homework except in the case of an unforseen emergency. Use your own good judgment about when to fax or email homework. In the event that you are suddenly unable to come to class on a given day, send your homework in with another student if possible. In case of unpredicted sudden emergency, be assured that one missing homework will not affect your grade. If you hand your homework in late by any means--such as running up to the front of the classroom after class has started, putting it in my mailbox, sliding it under my office door, or what-have-you, it will still be considered late. Excuses, even high quality excuses, do not render late homework acceptable for credit. Since homework will not be returned after grading you may want to make a copy for your own records.

Put your name, last name first, on the top left line of each assignment. On the top right, put the chapter number that the assignment covers. All assignments must be word processed, not handwritten.

The written assignments for this course are quite short. The reason for this that I want you to spend your time reading the assigned material and learning it. I believe that the thinking behind the written assignments will help you to learn the material.

For each chapter in the book your written assignment will be to:

1. Identify the research method(s)

2. Identify the variables

3. Write a summary of the findings that is not more than two sentences long and that confines itself to a description of the relationships found between the variables.

Identifying the research method or methods used in the study: While there may be more than one, you should identify what you believe to be the primary research method and to give a reason why you believe this. The primary method will almost always be one of three: a within-subjects experiment, a between-subjects experiment or a quasi experiment. In addition, studies may also be longitudinal, correlational, and use techniques such as surveys or naturalistic observations. If a study is obviously one of these secondary methods, you should list the method, but you do not need to describe why you think so.

Identifying the variables in the study: If the study is an experiment, these will be independent and dependent variables If the study is not an experiment, I think a good way to proceed is to try to identify what I will call "input" and "output" variables. These also go by other names within psychology--such as "subject variables," "predictors" and "outcomes." I prefer "input" and "output" as labels for these and I would like you to use these two terms, even though you should be aware that I sort of made them up and they may not be recognized by the field of psychology. In a quasi experiment, the input is the characteristic already possessed by the participant, such as gender or age. The output is what behavior or cognition is measured. . For studies that are experiments with additional quasi experimental outcomes, list independent and dependent variables as well as the input and output variables of the quasi experiment.

Here are some examples of methods indentification and variable identification:

Study example 1: Age differences in the understanding of the causes of AIDS. Male and female ten-year-olds, 15-year-olds and 20-year-olds are given a structured interview asking them to recognize causes and non-causes of AIDS from a list. It is found that all ages correctly recognize causes ("AIDS can be transmitted in blood and blood products..."), but that younger people are less successful at the identification of non causes ("You can catch AIDS from a drinking fountain...")

Method: This is a quasi experiment because the groups are defined by age, not random assignment. It is also a cross sectional study and an interview

Input variable: age

Output variables: correct identification of AIDS causes, correct identification of non-causes of AIDS

Study example 2: Male and female college students are randomly assigned to participate either in a program designed to increase self esteem or to be in a control group that receives a program about lawn care. After the programs, participants from both groups are individually observed in a social interaction with a complete stranger. This encounter is taped and coded for evidence of self esteem by trained raters. It was found that students who received the self esteem program showed higher levels of self-esteem. Additionally, females in the self esteem group showed more self esteem than males. Within the self esteem group of females, seniors showed less benefit from the program than freshmen.

Method: This is a between subjects experiment because the students were assigned to self esteem or lawn care training at random. It was also a quasi experiment and a naturalistic observation.

Independent variable: Self esteem training or lawn care training

Dependent variable: ratings of self esteem in social interaction

Input variables: sex, class level

Output variable: ratings of self esteem in social interaction

Study example 3: A single episode of the preschool educational program Blue’s Clues was shown once or repeated on 5 consecutive days to 3- to5-year-old viewers. A comparison group watched a different program one time. Children were assigned to groups by matching their ages and other characteristics as far as possible. Viewer behavior was videotaped and comprehension and learning of Blue’s Clues content was tested. With repetition, looking at the TV screen remained at a high level. Only 5-year-old boys looking decreased. Verbal and non-verbal interactions with the program (such as answering questions and pointing at the screen) increased, especially during educational content. Comprehension improved with repetition.

Method: This could be considered a between subjects experiment if one is willing to overlook the absence of actual random assignment to groups. It was a within subjects experiment for the comparison of children with themselves over successive viewings of the program. It was a quasi experiment for comparisons of age and gender. It also used a longitudinal approach and some naturalistic observation.

Independent variables: Repeated viewings, content of tape (Blue’s Clues or other tape)

Dependent variables: viewing behavior, verbal and non verbal, while watching tape, test scores of comprehension and learning

Input variables: age, gender

Output variables: viewing behavior, verbal and non verbal, while watching tape, test scores of comprehension and learning

I certainly encourage students to discuss course material including homework outside of class. However, your homework should be individually written and not be a communal project.

LATE HOMEWORK
Late homework will not be credited, as described above. However, if you have done it but not handed it in on time and want me to look at it, I will be happy to do so. I keep a separate late homework file where all late homework is stored. At final grading time, I try to find reasons to move grades up when they fall a tiny bit below one of the grade cutoffs. In looking for reasons, I will look at the late homework file. I will also consider total amount of class participation, quality of participation and quality of homework. If one or two homeworks have been completed but handed in late, I will probably use that as a reason to raise your grade the couple of tenths of a point required to get you into the next grade category. Do not confuse this procedure with the idea that late homework gets credit--it does not. Whether there is a lot or a little of it, late homework can only get you a few tenths of one percentage point when it comes to final grade time. The reason for this is that anyone can have an emergency or two in which homework ends up being late. In contrast, in the past some students have been chronically late in handing in much of the homework. If you can not get your homework in on time this is not a good section of PSY 101 for you to take.

Sometimes students will say that the homework policy is arbitrary, rigid and unfair. Two of these critiques are correct. I agree that the policy is arbitrary and rigid. All due dates are, in some sense, arbitrary. The point is homework has to be due sometime. There has to be some deadline after which homework will not get credit. I could make that deadline be the end of day the assignment is due; Friday of the week in which the assignment is due; the day before the final exam; or the minute before I take final grades to the registrar. All of these are arbitrary. No matter which one of them I chose, someone could come running up with late homework and miss the deadline.

The deadline is rigid because I want you to know in an unambiguous way when your homework is due. It would not be good for you if I was unclear about that, saying, for example, "hand your homework in any time." There would, of course, be some point after which it would not count, but you would not know when that deadline had passed. With the policy in this course, you know when it is late.

I disagree with those who say that a rigid homework deadline is unfair. Anything other than a rigid deadline is unfair, because it would mean that some students were getting credit that was denied to others. The only way to be fair is to have clear course policies and to stick to them

EXCUSES AND FAIRNESS
The reason why these policies are so detailed is that I want to be fair to everyone. My job requires the evaluation of your performance in this course, but I can not evaluate excuses. If I start to make exceptions to the course policies based upon reasons for lack of performance, I am not being fair to all the students. For example, imagine that the family member of a student experiences the sudden onset of a serious illness. I understand that a sudden serious illness in an immediate family member might result in missed class and late homework. Late homework does not get credit. If I were to accept that late homework for credit, I have made a judgment about the seriousness of the illness and the closeness of the family member. Is a heart attack serious enough? Probably. Is flu serious enough? Maybe, it depends upon other support persons available. Is a mother a close enough family member? Probably. Is a second cousin close enough? Maybe, I suppose it depends upon the history of the relationship with the second cousin. Do you see what I mean? I can not possibly fairly evaluate these things, so I must restrict myself to evaluating performance in the course.
The policies in this course are very forgiving. Attendance for any particular day is not required. A missed homework or two is will not affect your grade. However, massive absences from class with resulting lack of class participation and quantities of late homework will affect your grade because I am here to evaluate your performance in the class and those things are part of the evaluation.

ACADEMIC DISHONESTY
The college catalog defines academic dishonesty as: "the willful misrepresentation of any part or all of another’s work as one’s own. Copying another’s answers or giving or receiving unpermitted aid during classroom or take home examinations, assignments, papers, research reports and projects is cheating. Plagiarism in all its forms is cheating. Students have an obligation to themselves and to their peers to uphold the integrity of their institution by not participating either directly or indirectly in acts of cheating, and discouraging cheating by others. A students who aids another in cheating shares the guilt of the offense." In the sections of PSY 101 that I teach, the penalty for any kind of academic dishonesty will consist of a final course grade of "E".

COLLEGE EMAIL
I will sometimes communicate with the entire class by sending bulk email that automatically addresses each of you at your college email account. For this reason, you will have to check your college email regularly. I know that the college accounts tend to fill up with "@All" junk email, but this seems to be part of modern life and you should clean this stuff out of your account regularly. I cannot use non-college email addresses (hotmail, aol, etc.) to send bulk emails to the entire class. If you have a non-college email, then you will have to do what I do: check both and keep the junk cleared out.

GRADING
Your grade in this course will be my overall evaluation of your performance. I will base this evaluation on class participation and demonstrated competence on exams, participation, and homework. Proportional contribution of requirements that will help guide my judgment will be:
Hour Exams (14% each) 56%
Final Exam 14%
Participation 15%
Homework 15%

Final grades will be based on the percentage of points earned out of the total:
A = 93.0-100% A- = 90.0-92.99%
B+ = 87.0-89.99% B = 83.0-86.99% B- = 80.0-82.99%
C+ = 77.0-79.99% C = 73.0-76.99% C- = 70.0-72.99%
D+.= 67.0-69.99% D = 62.0-66.99%
E = 61.99% or BELOW

I reserve the right to exempt students from the final exam in cases where, in my opinion, performance has been consistently outstanding up until that point. This means that exams are consistently in the "A" range, homework is complete and on time, and participation is excellent. I call this the Poppinsien Exemption because, like Mary Poppins, you have to be practically perfect in every way in order to get it. Do not ask about whether you are going to be granted a Poppinsien Exemption. If you meet the criteria, you will be notified by me. The policies in this course have been crafted to assure that all students receive the same treatment. The application of all policies is subject to the discretion of the instructor.

WHY IS SHAFFER SUCH A MEAN PROFESSOR?
Sometimes students will look at all these course policies and ask themselves the question that begins this section. Really, mean is not the correct concept, demanding is a bit nearer the mark. There is a simple answer: The world is demanding and I want to prepare you for the world.
In your professional life after Plattsburgh:
1. Excuses will not replace performance.
2. Reading will sometimes be difficult.
3. Things will have to be done on time.
4. Consistent, not erratic, performance will be rewarded.
5. You will have to have to communicate ideas to others, sometimes to large groups

I would be shirking my responsibility as your instructor if I did not do my utmost to help you to build these transferable life skills. You may be able to find some three credit experiences that are less demanding than PSY 101. This will not deter me in any way whatsoever from offering you the highest quality educational experience that I can provide. That is why I am here.

HOW TO STUDY
Particularly following the first exam, I am often asked about how to study for PSY 101. There is no reason to wait until that time to become concerned about study techniques. My academic specialization is in biological aspects of psychology, I am not an expert in the area of study skills. There are study skill experts on campus and you will find some of them in the Learning Center in the Feinberg Library. Notwithstanding my lack of expertise, students often ask me how to study for this class. In order to try to help, I have put together few suggestions below from the published literature on study skills. It goes without saying that these tactics should be applied as soon as possible: they will not bail you out if you wait until you have already done poorly on one or more exams.

Suggestions About How to Study
1. Work on psychology by doing the assignments by the time they are due, a little bit at a time. No athlete would prepare for a big game by sitting around doing nothing for weeks and then staying up late the night before intensively working out. The same principle applies to learning. LEARN THE MATERIAL AS YOU GO ALONG. I have tried to assist you with this by having small amounts of reading due on specific days. You will have to take responsibility for learning the material as you go along. You should not have to spend hours studying for the exams. By the time the exam is near, you should already know the material.
2. Take responsibility for your own performance. Blaming roommates, textbooks, time of class meetings or whatever will not improve your performance. If you are not spending two to three hours in good, dense, quiet study for each hour in class, you are not doing enough.
3. At the end of each paragraph in the reading, stop and ask yourself what you have learned--if the answer is "nothing" read it again, and--if necessary--again. As you find important things, mark them with a highlighter or something in the margin--highlighting the lines themselves makes the book difficult to read. Important things are not just definitions. They also include study findings and summaries of areas of research. Read for about 45 minutes or so--after that your efficiency drops. Stop and do laundry for 15 minutes or something like that before you go back to reading.
4. At the end of each reading session, take the important things that you have found and write them out as questions--without answers--elsewhere in your notes or, better yet, on 3 X 5 cards. Put the text page numbers on them instead of answers. Alternately, put the answers on the back of the cards. If you have answers in front of you this will not be a good study aid. Do the same with your notes from class. Write these as multiple choice style questions, that is, put as much information as you can in the question. The answer will usually be a single word or two. Test yourself with these at intervals. If you can get someone else to do this too, ask them your questions and have them ask you theirs.
5. Study in a place which is quiet and in which you will not be disturbed. Plan to work very hard when you read and study. Many failing students think that studying is nothing more than reading the book over and over with the stereo blasting or the TV on and people running in and out while the phone rings. They spend hours at this, but they are not really doing anything useful. To make an analogy--it would be like trying to increase physical fitness by walking slowly and having an ice cream cone every two blocks. This is fun, but it does not result in a hard body. Laying around in front of a TV chatting with friends while scanning a book is also fun, but it is a complete waste of time as far as learning is concerned. To get fit, one must work the muscles, get out of breath and that sort of thing. In order to learn, one must WORK hard and intensely, focusing on the task at hand. No pain, no gain.
6. Study in the time of day during which you are most alert. Do not put studying off until you can hardly keep your eyes open. Successful students report that they make good use of the situation where they have an hour or two between classes. It is easy to waste that time by returning home and doing things of little consequence. Much work can be accomplished during the day by finding quiet places which are near to where your classes meet and hitting the books.
7. It is probably not worthwhile to re-copy your lecture notes after class. It is a very good idea, however, to take notes as thoroughly as possible in class, leaving some space as you are taking them. Then, as soon after class as you can, review the notes and clarify things you have not recorded in sufficient detail. This would also be a good time to work up the questions mentioned in Suggestion 3, above.
8. Tell the stories of the course to other people: parents, friends, partners or anyone. If no one will listen, tell the stories OUT LOUD to your dog, spider plant or desk lamp. I tell them to my dog Barney.The research articles are stories. Before exams, you should be able to tell these stories in considerable detail, without notes. This detail will include the research method, the main variables and the findings of the studies described in the chapter. That is how you can tell you know the material. At first, as you are learning the story, you will have to refer to notes, but as you tell it over and over, you will need the notes less and less.
Hint: point four (4) above is usually ignored by students who do poorly. Following these steps exactly will not be easy at first. If you do poorly on an exam, the first thing you will have to admit is that you have to do something DIFFERENT if you expect your grades to be different. A second thing you could have to admit is that you may have managed to get through high school and subsequent life without maximum efficiency in learning how to learn. Most students who do not do well are either (1) not working long enough or (2) not working efficiently

Frequently Asked Questions
Can I meet with you to ask questions about course content I do not understand or to further discuss topics or issues in psychology?
CERTAINLY. You can meet with me during office hours, you can make appointments for other times or you can find me most working days in the Sundowner from 7 to 7:30 AM. You can also ask questions on email if that is the easiest for you.

Can I meet with you to discuss my grade?
THERE WOULD BE NO POINT. Unless I have made a recording error, grades are determined by performance not by discussion with me.

Am I permitted to wear headphones during regular class meetings or exams?
NO

Is there extra credit available in this class?
NO

If I am absent because I am ill on a class day do I lose the homework point?
Only if your homework is late in being handed in.

If my homework is late for some very good reason, do I still lose credit for it?
YES

What if I am ill on exam day?
If you are too sick to take the exam, stay home and your score on the final will replace it.

Will I really be turned away if I show up more than 15 minutes late for an exam?
Yes.

Do you want me to bring you doctor's notes, athletic event schedules, or other excuses for absence?
NO

If I am in class but I do not sign the attendance sheet will I be counted absent?
YES. If, for whatever reason, you are there and have not signed the sheet, you should come up at the end of class and sign it.

May I go over exams with you?
NO. I could not do it for everyone so I can not do it for anyone. Concept lists will be posted on the appropriate webpager after the exam along with the answers to the exams. These will be available about an hour after the exam ends. You can make a copy of your answers during the exam and score yourself at that point. You should use the lists to identify and learn the concepts you have missed.

Do I have to know how to use the internet and email to be successful in this course?
YES. The complete course policies are only available on the course webpage. The page contains valuable information about a method of studying that has been quite successful for students who commit to using it.. In addition your grades will be updated weekly on the course webpage. Email is a good way of communicating with me--I will attempt to respond to your messages on the same day they are read.

If my printer fails to function as I am frantically trying to print my homework immediately before class, can I hand write it and still get credit?
NO. There is no reason why you should leave the printing of your homework until shortly before class. The assignments are made well ahead of time: be professional and complete them with sufficient time to deal with computer malfunctions.

If I sit outside the designated seats of the theatre just once will that lower my course grade?
YES, by 1%.

What are some other ways to lower my grade?
You can fail to answer questions in class or fail to code your name last name first on exam answer sheets.

Golly, are there more?
YES Others include: failing to hand in homework or failing to do the homework carefully and thoughtfully. If you really want to lose, the easiest way is to not show up to take the final exam.

f you cannot hear my answer to a question you have asked me, will you notify me and then wait until I say it loud enough?
NO. I will move along to someone else and you can try to be louder next time

What if I do not want to actively participate in class sessions?
You should select another course because 15% of your grade depends upon participation

Do you offer review sessions before exams?
NO, although I encourage you to form a study group with other students. Use your study group to quiz each other

Do you offer extra tutoring or study skills help in the course?
NO. Refer to the section above entitled "How to Study." If you need additional help you should see experts in places such as the learning center.

If I can not get to my own class can I sit in the other section of PSY 101?
NO

Do you bring pencils or erasers to exams in case I show up without one?
NO

Can I withdraw from this course after the final withdrawal date?
NO. The final withdrawal date for the semester is published in the college catalog
