At the end of each unit, DB participation is assessed based on level  of engagement and the quality of the contribution to the discussion. DBs  allow learners to learn through sharing ideas and experiences as they  relate to course content. Because it is not possible to engage in  two-way dialogue after a conversation has ended, no posts to the DB are  accepted after the end of the unit. Learners must demonstrate an  appropriate depth of understanding of course content to receive credit  for having submitted substantive posts. Typically, this is achieved with  3“4 strong paragraphs for Main Posts and 2“3 strong paragraphs for  Response Posts.
Deliverable Specifics 
Part 1 
What are some of the educational claims of popular tablets, laptops,  and mobile devices? Do you believe that these claims are valid? Can such  devices increase accuracy and speed of research projects? What  advantages and disadvantages do you see in online research? How might  you plan a research project to find the best and most reliable academic  resources for a project? How do your approaches differ from those of  your classmates? 
Part 2
Locate an advertisement or commercial that implies research study  results. Describe the claims made, and discuss how differences in  sampling of the population might create biased results. Discuss what  could account for the biased results. Read the posts of your classmates,  and respond with constructive feedback, suggestions, questions, and  additional resources as appropriate and in alignment with the AIU  Discussion Board Policy. You will be graded using the Grading Rubric  below.
In your own words, post a substantive response to the Discussion  Board question(s) and comment on other postings. Your response should  address the DB question(s) and move the conversation forward. You will  be graded on the quality of your postings, including mastery of the  concept as well as critical thinking. If asked for your opinion, do not  simply state that it is a good or bad idea; elaborate on your reasons  and argument. Include enough detail to substantiate your thinking as  well as your position on the questions or comments.
