II. OBJECTIVES -- Skills in Communication and Analysis
Questionnaire: Please return the attached questionnaire by Jan 16.
Entrance Exam: Introduction to information resources of the Science Library (Pass/Fail)
Exams: Two, based primarily on problem sets and presentations
Presentations: Two, each based on one paper from the primary literature
Written summaries: Three, each based on one paper from the primary literature
Lab reports: Seven (see Lab Schedule). The last will describe your efforts over several weeks to characterize an unknown transposon insertion.
Exams will be based largely on problem sets that will be assigned. They will require understanding of the primary papers presented during the semester, including those that you present. You will be permitted to use your book, notes, and any other aid that suits your fancy,... but no people. It is expected that during the course of the exam, you will not discuss matters related to the exam with anyone else.
You might wonder why this course places so much emphasis on communication and so little on the subject matter of molecular genetics. Imagine yourself ten years from now, when you've long since forgotten the intricacies of the lac operon and the "coding problem" is nothing more than a half-remembered catch phrase. Even so, whether you're preparing an acceptance speech that you, a world renowned neuroscientist, will deliver at Stockholm or instead preparing a more pointed speech that you, a harried houseparent, will deliver to your obstinate child, you will unquestionably find continued use for the ability to explain what you are doing in simple, understandable language. It is not a skill that comes naturally to most of us. We need practice.
Twice during the semester you will be asked to deliver a short (about 15 minutes) presentation of an article provided to you from the primary literature. Your presentation should accomplish four things:
I have given below a timetable that I strongly suggest you follow. All of us have gained facility in pulling together projects at the last minute, and no doubt you could, if necessary, figure out the paper a day or so before the presentation. However, if you go this route, you, like the vast majority of your colleagues in the past, will fail to consider the equal amount of effort required after understanding the article, to make it understandable to your listeners. As a result, for fifteen minutes you will cause your friends to suffer, wishing they were somewhere else, and you will be surprised to realize, in a very public way, the many important details of the presentation that you understand less well than you thought.
I wish to spare you this experience and to offer you a strategy by which you can plan a presentation in the detail sufficient to get the job done.
Steps in preparing a presentation:
III.C. Written Summaries
A summary should communicate the nature and significance of the problem addressed by the paper, the strategy employed to address the problem, the tools used in the study, the primary results, and important implications. If this sounds reminiscent of what I just said about a presentation, then consider that good communication is good communication. Young Hemingways in the class are free to use any appropriate format to realize these goals, but the rest of us should seriously consider following the general outline in Step 8 in the description of Presentations.
The summary should be written for an audience of people much like yourself, avoiding jargon and defining any terms you wouldn't expect your colleagues to be familiar with. It should end up about 1½ pages, double spaced, but the optimal length really depends upon the complexity of the paper. A sample is included at the end of this document.
Each paragraph should have a goal. If a phrase does not contribute towards the goal, then it detracts from it and should be deleted. Many people profit from writing an outline before attempting to write deathless prose. The outline need not be formal -- just setting down the substance of each paragraph without needing to worry about the niceties. Doing this after writing a rough draft may also be useful: if you find it difficult to outline the logic of your paragraph, there is a strong possibility there isn't any logic to outline.
III.D. Lab and Lab Reports
You will be handing in two types of lab reports: brief and full. "Brief" does not mean "unintelligible", and "full" does not mean "encyclopedic". Brief reports will be used for those labs in which you are provided detailed protocols. Full reports will be used for those labs in which you devise much of the protocol. In either case, the audience for which you are writing consists of people like you, before taking this course.
Brief reports: Begin with a reminder of what the goal of the experiment was and what methods were used to achieve that goal. A few sentences should suffice. Then lead the reader through the data you obtained, telling a story, and referring to labeled tables and figures as you go. Don't begin the report with a table of numbers that the reader couldn't possible understand. English first!
Full reports: Divide the report into four sections: Introduction, Materials and Methods, Results, and Discussion.
The Introduction should start with general questions and proceed from them to an exposition of the specific question (not necessarily a hypothesis!) that your experiment addressed. In the cases of Labs 2 and 4, your rationale for the experiment will need to connect with the articles on which they are derived. Use the articles as a starting point.
The Materials and Methods section should allow the reader to see the principles behind your experiment and how it might lead to results that bear on the questions they address. On matters of protocol, you may refer freely to any handout provided for this course, but you must detail any modifications or specifics particular to your experiment.
The Results section should be as described for brief reports.
The Discussion should first of all tie the results to the issues raised in the Introduction (you might want to first remind us what they were). Make a cogent argument for your conclusions, appealing to elements of your results. To what degree did the results resolve the issue? What is left unresolved? If you believe your data to be inconclusive, state why and what might have caused the ambiguities. Be sure that any explanations you put forward to explain deviations from expected results can quantitatively account for your actual results!
All assignments will be assigned a numerical grade based on the usual scale of 90-99=A, 80-89=B, etc. The final grade will be calculated based on a weighted average of all assignments. The weights used in this calculation are given below. The weights of each individual lab report is given in the Lab Schedule.
Exams 100 (= 50 x 2)
Presentations/Outlines 80 (= 40 x 2)
Summaries 40 (= 20 x 2)
Lab reports 190 (= [10 x 1] + [15 x 2] + [30 x 3] + [60 x 1])
Turning in assignments late makes life difficult for those of us who have to grade the assignment, and, eventually, to those of you who would like to receive the assignment back in a timely fashion. The purpose of late penalties is to discourage antisocial behavior but at the same time to encourage you to turn in something, sometime. To this end, every day late costs, but it is always much better to turn in the late paper than to not do it at all (which would generate a zero). An assignment is deemed late if it is turned in later than 5:00 P.M. on the day due. The maximum grade obtainable by a late paper will be calculated according to the formula:
where d is the number of weekdays late.
