The MCB 251 Web Gradebook can be accessed directly at:

       https://gradebook.atlas.uiuc.edu/courses/mcb251/fall08/index.html

Scores on exams and assignments will be available for student review on the MCB 251 Web Gradebook. To check your scores, sign into the MCB 251 Web site and click on the Gradebook link and follow the instructions presented there. All students are responsible for checking their scores on the Web Gradebook after each exam and assignment is returned to them. Each student is responsible for reporting possible discrepancies to their TA and if immediate action is not taken, the student is responsible for bringing this to the attention of Nicholas Kirchner within one week of receiving their graded paper or exam score. Students are encouraged to keep all graded papers returned to them until after final grades are issued.

The final deadline for Web Gradebook corrections is 5:00 PM, Wednesday, 10 December 2008.

No Web Gradebook scores will be altered after this deadline so please be certain to check all your scores before this time.



Laboratory Notebook Assignments

All MCB 251 students are required to keep a laboratory notebook. See Required and Recommended Materials section for the exact make of notebook required. The lab notebook assignments will be collected the week following the lab as per your Teaching Assistant's instructions. Keeping a thorough lab notebook is an essential part of scientific study and research. Your notebook should be legible and thorough enough for someone else to read and understand exactly what you did. Your laboratory notebook will be worth a total of 350 points this semester. There will be 8 notebook assignments each worth a total of 50 points, and the lowest score will be dropped (excluding exercise 5).Notebook assignments accompany the following laboratory exercises:

Exercise 1 Introduction to Microbiology/Microbiological Techniques
Exercise 2 Genetic Regulation
Exercise 3 Isolation of Spontaneous Mutations
Exercise 4.1 Plasmid Prep and Restriction Mapping
Exercise 4.2-4.4 Cloning, Transformation, Selection for Antibiotic Resistance
Exercise 4.5 Determining Orientation by Restriction Analysis
Exercise 4.6-4.7 PCR, Electrophoresis of PCR products
Exercise 5 Uknown Plasmid/Restriction Mapping

The point breakdown for each notebook assignment follows:

Pre-lab: To be completed before coming to class
6 points = Learning goals for the experiment; relevance of topic, data tables, procedure/protocol section

Post-lab:
4 points = proper format for the entire notebook assignment
15 points = data presentation and results section
25 points = conclusions and questions answered

The goals/relevance, procedure/protocols sections and data tables for results must be written in your notebook before coming to the lab. Data presentation, results and conclusions should be written in the notebook during and after the lab. The following guidelines are designed to ensure an accurate and detailed record of your laboratory experience. Your TA will provide you with specific details about exactly what is expected in your section.

1. All laboratory notebook assignments must be hand-written in the required Biology Laboratory Notebook. No typed assignments will be accepted. No credit will be given for computer-generated tables, graphs, or images.

2. Clearly write your name, section letter, TA's name and course number on the cover of your lab notebook. There are hundred of students in this course who are all using the same type of notebook, and should it be misplaced, we will be able to return it to you.

3. Notice that this notebook is carbonless. There are white and yellow sheets each with the same page number. Both sheets should be placed on top of the cover before you begin writing. Turn in the white pages of your notebook assignments and keep all yellow pages in your notebook for reference and proof of your assignment should it be misplaced. These pages must be in the notebook and in the natural order of the exercises to be useful should another copy of your assignment be needed. If you choose to prepare your assignments in some other way, you will bear the consequences should something become misplaced. The notebook carbons in sequence in your notebook are the only form of copies that will be accepted for credit.

4. Include a running table of contents at the front of your laboratory notebook so that experimental results can be located quickly and easily. Update the table of contents each time you begin a new laboratory exercise.

5. Write your name, section letter, TA's name, week number and date on the top of every page.

6. Errors should be crossed out with a single line so they remain legible. Do not erase or scratch out errors or tear pages out of your notebook. When an error is made, include a comment on what went wrong and what you would do differently if the experiment was repeated. This can allow you to figure out what actually happened even long after completing the experiment.

7. Each laboratory notebook assignment must include the following sections: Goals/Relevance of Topic: Begin with a short explanation of the goals of the laboratory exercise. Be certain to consider how one exercise relates to those you have done in the past and to those you will do in the remainder of the course. If plausible correlate what is being done in lab with topics and techniques that have been discussed in MCB 250 lecture.

Procedure/Protocol: Include a detailed description of what you actually did. This is an excellent opportunity for you to read the protocol as it appears in the manual and then process the information by writing it in brief using your own words. Provide sufficient detail so someone could repeat the experiment exactly the way you did it. You should not re-write the procedure directly from the manual. It is very unusual for a procedure to be performed exactly as written, so you must specify any changes or differences (accidental or intentional) between the procedure and what you actually did in the lab. It is good scientific practice to record any deviations from the standard procedure so that the experiment can be duplicated exactly. Careful notes can prevent similar problems from occurring in a repeat experiment. Show all calculations that are necessary to proceed through the experiment. For example, indicate how dilutions are done. Do not count on your memory, write all observations in your notebook while you are doing the experiment.

Data Presentation/Results: Include the actual raw data in your notebook as well as any graphs, photographs, tables or calculations based on the data. Affix any supporting materials (e.g. photographs, print-outs, or graphs) directly into the notebook. All attachments should include the date and details about how they were obtained (e.g. how long a photograph was exposed, the settings and type of the spectrophotometer, etc.) A photocopy of your lab partner's table or graph is unacceptable even if you participated in the collection of the data. You must always present the data in your own, original way.

Conclusions/ Questions Answered: Include a summary of the conclusions. What were the controls? Did the controls work? What were the varied elements? How were they varied and why? What do the results mean? Are they the results that you predicted/expected?



Current Events Presentation

During several labs throughout the semester, each set of lab partners will do one 8-10 minute presentation about a current event in science or medicine. A sign up sheet and additional information will be provided during the semster. The presentation will be worth 40 points.



LON-CAPA Pre Lab Assignments

These will be open 24 hours before your lab section meets each week and will be worth 3 points each. There will be 12 prelab quizzes (drop 2 lowest). Questions will cover content from the weekly video lectures and the background reading in the lab manual for each respective exercise. Once you start the quiz you will have 10 minutes to answer and submit questions. A total of 30 points may be earned for LON-CAP prelab quizzes.



LON-CAPA Post Lab Assignments

These will be 11 post lab assignments at the end of each exercise and will be worth 13 points each (drop lowest). Questions will test your understanding of the lab exercises and be conceptually based. Post-Lab questions will be opened at the end of your respective lab sections and closed the following week at the beginning of your next lab. You may work on these questions from any computer that has internet access. Please be advised that difficulty accessing the server, inability to find an open computer lab, or other computer issues will not suffice to extend this deadline. Please be sure to finish your assignments early, to avoid missing the deadline! A total of 130 points may be earned for LON CAPA assignments. LON-CAPA can be accessed directly at: http://www.lon-capa.uiuc.edu Instructions for LON-CAPA access can be found on page I-23 of the course policies.



EXAMINATIONS

Evening exams and the final exam will be a combination of multiple choice, true-false, matching, and short answer format. Material for evening lecture exams will be drawn from the, laboratory lecture videos, laboratory presentations, discussions, laboratory notebook, and assigned readings, if any. Material for the final exam can be drawn comprehensively from all material covered in the course. TAs will provide students with information regarding the content of specific exams.

All short answer questions are graded by the Exam grader and the grades are entered into the Web Gradebook. Once the exams have been administered, they become property of the students. It is the student's responsibility to make certain that the grade on the Web Gradebook is correct. If a student believes that an error has been made, it should be brought to the TA's attention immediately. If an explanation cannot be found, the student and/or the TA should bring the problem to Nicholas Kirchner or the MCB 251 Staff in 252 Davenport Hall. All student scantron sheets are retained for grade confirmation if necessary. All students are urged to keep their errata sheets until a final grade has been issued for the course.

The final exam is the property of the course and is not returned to students, nor are answers posted or made available in any way. Should a student feel that an error has been made in the grading of the final exam, that student should contact Nicholas Kirchner.

STATEMENT ON ACADEMIC INTEGRITY

  1. Science cannot exist without honesty. The faculty and staff of MCB 251 require students, as scientists-in-the-making, to hold the highest standards of scientific and academic conduct. Any form of cheating on any graded work in this course is unacceptable, and will be dealt with as outlined below, and in accordance with the University-wide standards in the Code of Policies and Regulations Applying to All Students.

  2. We require that all graded work be entirely your own, and that anything you write using the words of other writers be correctly attributed. Some specific points follow:

    1. On all exams, the answers that your turn in for grading must be your own, formulated during the exam from your own understanding of the material and without any supporting information, be it written, verbal or electronic. Copying the work of another student, or allowing another to copy your work, or copying work from any other source, is unacceptable. Since we can not always monitor you as you complete your work, we must rely upon appearance of your work from which to judge. If the work you submit resembles that of another student or another source too closely, we may conclude that it was not your original work. Always make a conscious effort to complete your work on your own and to protect it from the view of others, in order to ensure that it will be seen as your own. Failure to adhere to these standards, for any portion of an exam, may result in a grade of zero for the entire exam, for all persons involved.

    2. On assignments, the answers that you turn in for grading must be written in your own words, formulated from your own understanding of the material. Copying or paraphrasing the work of another student, or allowing another to copy or paraphrase your work, is unacceptable. Since we can not monitor you as you complete your work, we have only the appearance of your work from which to judge. If the work you submit resembles that of another student too closely, we may conclude that it was not your original work. Always make a conscious effort to complete your work on your own and to protect it from the view of others, in order to ensure that it will be seen as your own. Failure to adhere to these standards may result in a grade of zero for the entire assignment, for all persons involved.

    3. On assignments, if you use a statement taken directly from any book or other publication, including the course textbook, you must provide a citation. That is, you must put the text in quotes and put the author of the publication in parentheses after the quotation. Failure to do so will result in zero credit for that answer. Further, using only the words of another author as your entire answer or as the majority of your answer to any question is never sufficient to earn credit. If the majority of your work has been taken directly from a publication, you are likely to receive no credit for the work, since you would not be demonstrating knowledge beyond the ability to copy. Even if you quote another, your answer must be substantially your own words, drawn from your own understanding of the material.
