505 discussion week 4
Your active participation in the weekly Discussion is important to the shared learning experience. Active discussion also develops our community of budding counselors, therapists, and researchers. Please participate as early in the week as possible, and be sure to share your thoughts and ideas as often as you can throughout the unit.
Respond to the threads. Your original response should be at least 350 words and should reflect the fact that you have completed the assigned readings for the week. Remember, this is your chance to illustrate not only your understanding, but also your mastery of the materials for the unit. Use your words wisely so the posting has substance and includes examples and explanations. Limit the use of direct quotes, and do your best to critically evaluate and synthesize the literature in your own words wherever possible. Make sure to include in-text citations and a reference list as appropriate.
