The in-class quizzes will test your completion of the assignments for last week. They will be 20 to 30 minutes long and given in class. We will have twelve quizzes, one each week.  
+
<!-- Our in-class evaluations - or "Quizzes" - will test whether you completed the assignments and allow you to catch up with important concepts. They may also include questions about the broader context: concepts and methods, especially their computational aspects. Also, at times, you may be asked to bring material to class (see below).
  
−
Typical questions will ask about your experiences while going through the assignments, and your basic understanding of concepts - what you where doing and why you were doing it. I try to make these questions easy for anyone who has completed the assignments with an active mind. It should be possible to get a perfect score on all of them.  
+
These evaluations (normally) consist of five integrated parts: collecting questions, review, quiz, take-up, and final assessment.
 +
-->
  
−
There may also be questions on the concepts and methods, especially their computational aspects. You may be asked to give your opinion on possible improvements or generalizations and to think through some "problem solving" questions. It may be useful to discuss your understanding with your classmates in person or on the mailing list.
+
BCB420 will have a single quiz to test the specific preparation units assigned for weeks one and two, and general knowledge of introductory bioinformatics.
  
−
You are welcome and encouraged to submit quiz questions to me or to the course mailing list. I always consider these carefully and often include such questions (in slightly modified fashion). It is a chance for me to better understand your background and expectations, and for you to think about the material in a structured way.

Prior to the quiz, we will hold a practice quiz. You are also encouraged to discuss preparatory contents on the mailing list or on Slack.<!--'''collect interesting questions''' on the [http://steipe.biochemistry.utoronto.ca/abc/students/index.php/CurrentQuizzes Student Wiki]. A more detailed discussion on Quiz questions is [http://steipe.biochemistry.utoronto.ca/abc/students/index.php/CurrentQuizzes '''there'''], we strive to identify checkpoints in the material that demonstrate your understanding and the ability to put what you have learned into practice. Pure memorization questions will probably not make it to the actual Quiz, good questions should stimulate you to think. Designing, writing, <u>editing, and improving</u> these questions can contribute to your participation mark. I will compile the actual Quiz largely from these questions, so if you know how to answer them, you will be well prepared.
 +
 +
I really need you to think along with the course, and designing your own quiz questions is an excellent way to do this.  -->

You write the quiz with a black or blue pen. The rules are the same as for other academic evaluations. This includes: Don't write after time is up. Don't look at your neighbour's work.

Immediately after writing the quiz, you will '''assess how you did''' while we discuss the answers: you will mark your answers with a <span style="color:#DD0000;">'''red'''</span> pen and you will make sure the correct answers are recorded on your sheet: if you got it wrong, point out the error and write down the right answer. This is crucial: at some point you need to have the correct answer written down, either when you originally wrote it, or as you were marking. If the answer still isn't clear to you, ask, ask again, until you understand.

Let me repeat this. If you got something wrong, write down the correct answer (with a red pen).

You may miss up to two quizzes. For these, I will record the marks of the (lower) 25% quartile of your other quizzes. If you miss more than two quizzes and don't want to lose the marks, we will proceed in analogy to missed exams' regulations. You will need to petition to me with an acceptable reason and documentation (TBD case by case, contact me in advance) and we will need to schedule a make-up opportunity, typically an oral exam.

"Quizzes", Self-Assessment and Feedback


 


BCB420 will have a single quiz to test the specific preparation units assigned for weeks one and two, and general knowledge of introductory bioinformatics.


 


 

1:

The topics that are relevant for this quiz include:

  1. Principles of R and R programming;
  2. How to work with Wikis, in particular how to maintain a Lab Journal;
  3. Configuring your computer for biocomputing;
  4. General preparation including how to avoid academic offences, Netiquette and how to ask technical questions;
  5. The genetic code, DNA, RNA and protein sequence and how to manipulate sequences;
  6. Basic bioinformatics databases
  7. Functional annotation of genes
  8. Principles of expression data management and analysis
  9. Local and global pairwise optimal sequence alignment, BLAST, PSI-BLAST and multiple sequence alignments
  10. Genome data


(Not: phylogenetic analysis and structural bioinformatics)

Take the actual "Quiz", it will be about 30 minutes long. I'll hand out the questions, you keep the page face down on your desk until you may start.

You write the quiz with a black or blue pen. The rules are the same as for other academic evaluations. This includes: Don't write after time is up. Don't look at your neighbour's work. Don't look at the work of the guy next to your neighbour either. Don't show your work to your neighbour. Don't use unauthorized aids. Don't communicate with others while the quiz is being written.

Changing marks?

In all cases in which you believe a grade or partial mark is not correct, e-mail me. I will not adjust marks based on verbal discussions after class, in the corridors, or elsewhere. E-mail me with specifics, and back up your views with evidence. I will correct errors, but please note that marks are not "negotiable" merely on the basis of opinions.
