Bi 1 Policies

Grading

Contributions to your grade
Component Weight Comments
Problem Sets 28% There are 8 problem sets @ 3 to 4%. Collaboration is allowed (see collaboration rules below). Problem sets are generally posted on Monday and due at 5 PM the following Monday in the Bi 1 closet*. The only reasons acceptable for full credit on late problem sets are formal medical or Dean's excuses.
Recitation Sections 12% You are evaluated by attendance and by contributions to the discussions.
Midterm (covers problem sets 1-4) 28% The only reasons acceptable for full credit on late exam are formal medical or Dean's excuses.
Final (covers problem sets 1-8) 32% The only reasons acceptable for full credit on late exam are formal medical or Dean's excuses.

* The Bi 1 closet is 4 m South of the East entrance to the lecture hall (119 Kerckhoff).

Without a formal excuse from the Dean or Health Center, homework will have 10% credit deducted for each day that it is late (in other words, up to 90% credit if one day late, up to 50% if five days late, and so on). Make sure to write the date and time of submission at the top of each problem set.

Pass/Fail Grading

Students may opt to take Bi1 pass/fail instead of on letter grades. The last day for exercising the pass/fail option is drop day: May 21st, 2008. Students who take Bi1 on pass/fail must earn a 60% or higher course grade in order to pass.

Course Conflicts & Conflict Cards

We strongly urge you to take Bi1 only when your schedule allows you to devote your full attention to the class. However, we understand this is not possible for some students and will, in certain cases, sign conflict cards.

Collaboration

Problem SetsExams
While working, you may consult:
Required texts
Recommended texts
Textbooks from prerequisite classes (i.e. Chem1)
English language dictionary (electronic, hard copy)
The Bi 1 Glossary
Reference books (CRC, Merck Index, etc.)
Any other texts or journal articles: (cite appropriately) 
You may use a computer as a word processor
The Internet: (give URL for site) exam website only
Notes. You may use:
Your class notes (taken in lecture)
Hand copies of the class notes of others
The class notes of others (original or Xeroxed)
Anything written in your own hand
Class handouts
TA/section handouts
Homework/exams of past years  
Homework/exams of this year
Solutions to homework/exams of past years    
Solutions to homework/exams of current year
For computational aids, you may use:
Calculators, computer as calculator, and slide rules
Mathematical reference tables (integrals, Laplace transforms, etc)
Collaboration:
Tell another student that the question exists 
Basic discussion of the problems 
Look at communal materials while writing up solutions 
Look at other's individual work (i.e. writeups)  
Sharing a session on Swiss-PDB or other computer-based exercise  
Discussing how to use Swiss-PDB or other computer-based exercise 
Turn in a set with more than one name on it  
Sharing communications to or from TAs 
Comparing answers to completed problems 

  1. You must answer in your own words.
  2. In addition to these guidelines and rules, obvious copying (even a single sentence) is not allowed.
  3. You must feel that you can personally reconstruct the entire response.

The Honor Code

Students should understand that Caltech's Honor Code is good preparation for the equally stringent ethical requirements which are imposed by employers, publishers, and granting agencies. Your instructors abide by the Caltech Honor code and will not tolerate any behaviors that take unfair advantage of others.

Homework

Copying of other people's work is not permitted. You may consult with others on the problem sets, but the written work must be done independently by each student.

Plagiarism

Below is a statement from the Caltech Honor System handbook (2000):

In collecting data and information, students need to actively avoid plagiarizing the work of others. Proper footnoting of source material and documentation of borrowed ideas are absolutely essential. Many professors are willing to show students how to correctly document their papers. Plagiarism, whether inadvertent paraphrasing or direct substitution, takes unfair advantage of any original authors, the instructor who incorrectly believes that the ideas are the plagiarist's, and other students who correctly footnote all sources.

In Bi 1, this policy applies to all written work submitted for the course. Although you may include sentences from the work of others in your homework, you must enclose the sentences in quotation marks and provide a proper reference for the quotation (see example below). If plagiarism is discovered in any course work, we will notify the Board of Control and the grade will be impacted accordingly.

Material cited verbatim should be formatted as in the following example:

"Copying material verbatim from a source and not explicitly quoting it and citing it is plagiarism. Students who plagiarize should expect a very poor grade." (Bjorkman and Rees, 2004; Clemons and Rees, 2006).

Also, ideas and results must be cited even when the source text is not used verbatim and the material cited is not quoted. Example:

The E. coli protein MutS repairs DNA mismatches (Su et. al., 1988).

Senior Policy

Due to the timing requirements of graduating seniors taking this course, they will not take the final. Instead, they will be required to write a paper based on one of the following books or movie:

There will be specific guidelines posted later for the papers, including questions that must be addressed depending on the book chosen. Around the time of the midterm, graduating seniors must identify to the Head TA which topic they plan to write on, and further guidance will be given. We welcome suggestions for alternative topics or resources, but they must be approved in advance by the instructors.
