PY105 Honor Code

I agree to act with complete honesty in PY105. This includes, but is not limited to, the following:

All work I turn in will be my own, and not copied from any other source.

For in-class questions that require the use of a transmitter to respond, I will submit responses using only my transmitter.

I will not submit responses for anyone else.

In addition to being reported to the Academic Conduct Committee, examples of grading penalties might include:

Zero on an assignment if you copy the assignment, or let someone copy from you.

Zero on a test if there are copying issues, or other examples of misconduct.

I have read through the PY105 course syllabus. There is a link to the Academic Conduct Code on the PY105 blackboard.bu.edu web site, and I have read that, too.

Disclaimer

It is a well-known fact that different people might have different taste in food or art.

Your friends might love horror movies but you might hate them, or you might like sushi but your friends will never eat it.

The same is true for choosing your instructor. There is no teacher who would be equally good for everyone. Different people have different learning stiles and unfortunately it is just impossible to accommodate every student in a classroom offering lectures, exercises, questions, demonstrations, etc. equally effective to everyone.

Students who had taken this course gave usually a positive feedback, but there are two “negative” remarks which had been provided on a regular basis:

1. this course requires too much reading in order to be prepared for lectures;

2. some of the examples are not getting finished during lectures.

I have to point out that by the design of this course:

1. reading the textbook ahead of the lectures is a requirement (this is a part of the pedagogical technique known as Gutenberg Method);

2. some of the examples might involve a simple or a long math manipulations which do not deserve lecture time (having a basic math background is a prerequisite for this course and any math-related difficulties can be easily resolved during multiple office hours).

Summer courses are always more intense than fall or spring courses because the same amount of material is to be covered over a shorter period of time. Students should expect spending on average two hours every day on reading and homework (in addition to lectures and investigative laboratories).

There are many BU Physics Department faculty teaching similar courses and if you feel the summer course is not designed the way you would like it to be designed, you can defiantly find an instructor who fits better your expectations.

About this course

It is advisable to sign up for the both PY 105 and PY 106 summer courses, in that case you will be using the same textbook for two courses (the best way is buying it online).

This course is very much different from traditional courses by its main philosophy and structuring. It is built up on the principles of constructivism and employs inquiry-based strategies of teaching.

In a standard undergraduate course an instructor provides students with basic concepts and ideas, which have been developed in the field. Students should get some hand on experience in the labs, and discussions should provide students with example of applications of basic concepts and ideas to solving problems. Students have to develop on their own the specific problem solving skills important to the field of study.

In this course students develop the fundamental concepts and ideas while working through combined discussion/lab activities. The lecturer guides the students through problem solving techniques and procedures to help them to learn how to apply the fundamental concepts to solving specific physics problems. Then using an Active Learning Group format, students form collaborative groups to discuss problem solving strategies. However, when giving an answer using the personal response system, each student is responsible for his or her own answer. Thus a standard lecture becomes a place for a scientific communication between peers and for knowledgeable individual decision making in the field of physics. The ultimate goals of the course are helping students to grasp the fundamental physical concepts, to learn how to apply those concepts to solve specific physical problems, to advance the ability to think critically about physical phenomena, and to support positive attitudes toward study physics.

In this course the choice of a textbook does not matter as much as the choice of a set of problems students should learn how to solve. Any standard textbook, or lecture notes posted on the course web site, or a reasonable online source, will give students all the general information about the fundamental concepts and ideas in physics.

Most of the problems (in-class problems, home work problems, test problems) will be taken from the recommended textbook “Physics: Algebra/Trig” (the latest edition has the fewest typos, but any edition will work; the CD is not required but could be useful for self-study), written by Eugene Hecht, who is a well-known physicists and educator. The best way of buying the book is via online stores such as amazon.com.

A problem solving oriented approach to teaching solves the accountability issue and offers a universal and fair way to assess students’ level of conceptual understanding and of mastering problem solving skills. It is our belief that if a student can solve any problem similar to about 500 standard physics problems, that student deserves an A for the course.

Acknowledgments

I am thankful for the shared experience of teaching and for the many ideas and teaching materials developed when working together with Prof. Duffy, Prof. Tsui, Prof. and Rohlf. A special acknowledgment is to Prof. Skocpol for his support in developing this course.

Using WebAssign

WebAssign is a web-based homework system we will be using for most of the homework. There is an excellent guide to using WebAssign on the WebAssign web site - please read through this before submitting the first assignment. Please contact Prof. Voroshilov if you have any problems, particularly if you have problems logging in. The web address for WebAssign is: http://www.webassign.net/student.html

You will need to buy the access (good for one semester only!) directly from WebAssign with a credit card (you may buy the access with the electronic version of the textbook instead of having a hard copy of it). To do this, log into WebAssign using the information below and then hit the button for registering with a credit card. Note that you can do the first assignment without paying for access - you get free access for the first two weeks.

You will need to enter three pieces of data to log on to WebAssign or to order an access code from WebAssign. These are:

Username: Use your regular acs login name
Institution name: bu
Password: Your password is your BU student number in the form U12345678. No dashes or spaces!

** Note that if you have used WebAssign previously at BU, such as in Chemistry, then WebAssign will be looking for your old password.

Getting the most out of WebAssign

You have six chances to submit each answer on each homework assignment. Use your submissions wisely. Note that you can submit the answers to each question individually - you do not need to fill in answers for the whole assignment first. Each time you submit, WebAssign tells you whether you are right or wrong, and then you get more chances to correct anything you got wrong.

Things to keep in mind when using WebAssign:

- Start early.
- Come to office hours for help.
- Feel free to work together with other students, but try to do as much as you can on your own.
- Do not hit the refresh button on your browser - that can count as a submission.

Most of the test problems will be based on problems from the textbook and on the lecture and homework problems. Additional useful sources are textbooks of such authors as A. Duffy, Cutnell and Johnson, Giancoli, Ohanian, Halliday, Resnick, Walker. You also can use online resource like Wikipedia.org; http://hyperphysics.phy-astr.gsu.edu/hbase/hframe.html; physics.bu.edu/demos; etc.

Course web site: http://blackboard.bu.edu

Your login name is your regular BU acs login name and your password is your acs kerberos password. In case of any problems, please contact Dr. Voroshilov (valbu@bu.edu). If you do not have an acs account you must get one. You can start the application process on-line at  http://www.bu.edu/computing/accounts/acsaccounts/creating/ (BU students should use the "Individual" instructions; non-BU students should use the "Guest" instructions); and you will need to go to 111 Cummington to complete the process.

The web site contains all course information. You will also be able to check your grades (labs, homework, quizzes, etc.) during the semester. It is your responsibility to check that your grades have been recorded correctly.

Homework:  To pass the course you must get at least 50% of the maximum possible homework score.

Homework assignments will be delivered via WebAssign. The numbers and/or variables in the on-line assignments can be randomized so everyone gets a unique version of any problem. These assignments usually are due at 10 pm on the due dates, adjusted somewhat for schedule peculiarities. All homework assignment will be accounted for the final grade.

You are strongly encouraged to obtain help (if needed) during lab/discussion unit sections and/or during office hours. In addition to Dr. Voroshilov’s office hours, you can use the office hours of any TF of the class (the schedule and other course information is posted on the course board in the Science Building on the second floor between the offices SCI 263 and SCI 264).

Discussion sections and traditional laboratories are combined together in 11 Investigative Laboratories (or shortly, IL, or units): These begin on Tuesday, May 22. Much of the time in IL will be spent working with your partner on discovering, and/or analyzing and applying fundamental physical concepts and relationships. Laboratory activities are combined with problem solving activities. The best 10 unit scores out of 11 will be counted toward the final grade. Unit assignments are only complete when your personal report is checked by your TF during and at the end of the unit session. Your unit report will consist of copies of your data together with your answers to questions on a sheet(s) handed out at the beginning of the unit session.

All sections are usually held in room SCI 134 but occasionally can be relocated. The room assignments for a particular week will be posted on all lab doors - please, pay attention to the information provided on blackboard.bu.edu.

Lecture: To get the most out of the lectures you should read over the material ahead of time (below you find the list of topics and concepts with which you should be familiar when coming to lectures).

Exams: Three closed-book tests will be given. Equation sheets with the most common equations will be provided, too, but it is advisable to memorize the most important physical laws and relations. Concerns about grading must be brought to Dr. Voroshilov’s attention within one week after the tests are returned. A random sample of tests will be photocopied before being returned to discourage cheating on re-grade issues.

If any accommodation may be needed, the request must be processed within the first week of the course. In exceptional (unforeseen) circumstances an arrangement may be made to take a make-up test. Such an arrangement must be approved IN ADVANCE OF THE ORIGINALLY SCHEDULED TEST DATE no later then one week before the test.

Makeup policy: It is your responsibility to take all quizzes/exams and do all homework and unit assignments according to the posted schedules. There are NO makeups. In exceptional circumstances please contact professor Voroshilov as soon as possible.

Switching sections: We encourage your switching from full to less full discussion/lab unit sections. You need Dr. Voroshilov's signature on a drop/add/section-change form.

Getting help: The best way to get help is fully using unit time and to come to office hours. Between the professor and the teaching fellows there are about 20 office hours per week - please come and see any of us.

Ethics Policy: You are expected to be familiar with and adhere to the College of Arts and Sciences Academic Conduct Code. In particular, cheating on exams and quizzes or unauthorized collaboration on lab work will not be tolerated. Evidence of cheating will be reported immediately to your Academic Conduct Committee. Students found guilty of cheating on exams may be penalized by suspension or even expulsion.

All students will have to sign an honor code on the first day of class (see below)
