Data on Response Times

Filed in Announcements, Data Links

Screen Shot 2014-08-29 at 6.01.03 AMHere is the raw response time data. The file was pieced together from all the submissions. The groups were not consistent with their files. Take a look over the files and identify at least two problems. Send me an email with solutions to those two problems and I will send you back a clean data file (thanks to Allen).

Britt’s Tips on Studying

Filed in Studying and Learning

Screen Shot 2014-07-27 at 4.27.56 PM

In the linked podcast, psychologist Michael A. Britt discusses some of the evidence based tactics related to learning.

His important take-home messages are:
1)   Self-testing is more effective than rereading material.
2)   Self-test multiple times, even when you know it the first time.
3)   Explain the material to somebody else, or yourself if nobody is available. Written/pictorial explanations require your thought process to be completed and closed.
4)   Identify and articulate the distinctiveness of each new topic.
5)   Apply and connect the topic. In science we can’t always make connections with a topic to our personal life. We can still try to apply it to authentic scientific settings. Our coursework provides opportunities.
6)   Don’t confuse familiarity with a topic with understanding and ability to use related tools.

Things to keep in mind:

  1. When Michael talks about studying he is talking about rereading the notes or the text. In Biology 200 when we talk about studying we refer to all of the activities related to learning the material including, but not limited to, reading and things Michael suggests.
  2. The scope of the podcast is not comprehensive. There are many more activities we can add to the studying arsenal.

Notes
Odd numbered questions are briefly answered at the back of the book.

If you are unable to answer a question or are unsure of the answer, identify the part(s) of question/answer that you do not understand and/or cannot answer.

Record the following with your completed homework answers:
• The question number
• What part of the question/answer you do understand
• Which specific part of the question/answer is confusing, needs clarification, or explanation. Please quote.
• Which specific pages you believe are most related to the question and how you attempted to resolve the issue

The above format should be used when presenting questions to your professor.

Reminder of the Course Workflow
Assignments are issued on Tuesday. Questions about concepts and applications are due before Monday. Materially complete/attempted homework is due the following Tuesday. An assessment will follow about one week later.
