Build your own quiz by making a list of 5 take-away statements about Week 2 content. This may include anything from the textbook, lecture videos, articles, videos, websites, etc. Post your list under the discussion board prompt titled Quiz 2. Click the Discussion Board menu tab to access the prompt.What is a Take-Away Statement?
- A one to two-sentence original statement about something you learned. Each statement is in your own words, and reflects critical thinking about the content.
- Example: Unlike caterpillars, beetle larvae do not have suction-like back legs.
What is NOT a Take-Away Statement?
- Direct quotes from class material.
- Lists of facts pulled from course material and/or outside sources (i.e. google, wikipedia, etc.)
- Incomplete sentences.
- Example: I really like beetles because they are cool. (This shows no connection to something learned from the class. Although it’s good to include your thoughts, make sure you are also communicating a connection to something learned in the course.)
- Example: Beetles are the largest order of insects. (This is a straight fact that is too similar to course textbook material.)
How will you be graded?
- Credit/ No Credit.
- College-level writing is required meaning no grammar/spelling/editing errors.
- All 5 statements must be present and original work.
- Please note that the only way that a student will not get credit for this assignment is if statements are taken directly or almost directly from one of the sources of information listed above. Just changing one word will not be acceptable either. Students must think critically about the information they have received thus far and simply type out a bullet list of 5 “take-away” statements.
