All students should complete one of the following written case studies from Anderson (2013) for this lesson. Two references are required for each case study (one reference must be the 2019 Hallahan, Kauffman & Pullen course text); the citation for the reference and the specific page number or exact web page must be inserted immediately following the content that is supported by the reference. Half credit will be given for cases that do not include the two required references. See the syllabus for a more complete explanation of case study response requirements and a sample case study that provides the correct referencing format. This report must be submitted as a file or text entry in the assignments box. Students are required to check that the file was sent; if there was a problem with the assignment, students may immediately resubmit through Canvas Conversations with no penalty. This assignment will be accepted one day late for half credit.
