湿度控制器哪个好:在线教师促进讨论的方法

Susan Levine (2002)
1. The instructor will start each discussion by posting one or
more questions at the beginning of each week (Sunday or
Monday). The discussion will continue until the following
Sunday night, at which time the discussion board will close
for that week.
2. Please focus on the questions posted. But—do bring in
related thoughts and material, other readings, or questions
that occur to you from the ongoing discussion.
3. You are expected to post at least two substantive messages
for each discussion question. Your postings should reflect an
understanding of the course material.
4. Your postings should advance the group’s negotiation of
ideas and meanings about the material; that is, your
contributions should go beyond a “ditto.” Some ways you
can further the discussion include:
• expressing opinions or observations. These should be offered
in depth and supported by more than personal opinion.
• making a connection between the current discussion and
previous discussions, a personal experience, or concepts
from the readings,
• commenting on or asking for clarification of another
student’s statement,
• synthesizing other students’ responses, or
• posing a substantive question aimed at furthering the group’s
understanding. (Levine, 2002)
Nada Dabbagh (2000),
• Postings should be evenly distributed during the discussion
period (not concentrated all on one day or at the beginning
and/or end of the period).
• Postings should be a minimum of one short paragraph and a
maximum of two paragraphs.
• Avoid postings that are limited to “I agree” or “great idea,”
etc. If you agree (or disagree) with a posting then say why
you agree by supporting your statement with concepts from
the readings or by bringing in a related example or
experience.
• Address the questions as much as possible (don’t let the
discussion stray).
• Try to use quotes from the articles that support your postings.
Include page numbers when you do that.
• Build on others’ responses to create threads.
• Bring in related prior knowledge (work experience, prior
coursework, readings, etc.).
• Use proper etiquette (proper language, typing, etc.).
