Delphi Procedure • Complete a survey in which respondents answer a number of open-ended questions • From these responses, create a new survey that lists all the open-ended responses, and the number of respondents that wrote each response • Respondents rate their agreement with each statement on a five-point likert scale, (1) meaning "strongly disagree" and (5) meaning "strongly agree." • Statements with means of 4.0 or higher and standard deviations below 1.0 are designated as areas of agreement • With this information, one can compare like responses over time (pre and post test), conduct factor analyses (given sufficient sample size), and other statistical tests
Why Delphi method? • Focus groups can be difficult to manage • Assumption of anonymity could be violated • “Reticent” versus “generous” respondents • Power dynamics
Why Delphi method? • Rating consensus based on open-ended responses might be helpful/meaningful • Allows for a natural means of conversation about how results can be used because participants can also be the decision makers • When combined with other findings, can add specific information (e.g., adds meaning to state licensure exams, etc.) • When systematically managed, might include faculty’s review of student work samples, making it more of a “direct” observation of student performance • Might also be a way of getting employers, intern hosts, alumni, and others to participate • Can be managed electronically, without requirement that all participants sit in one room at the same time
Case Study: Construction Management Assessment Study • Its program accreditor, the American Council for Construction Education (ACCE), required a submission of a self study; in the self study, faculty had to assess eighteen student learning outcomes • The faculty had only six months in which to conduct alumni, employer, internship studies, in addition to some direct assessment of student work • There was no capstone course or other place in the program where students could be assessed on all accreditation student learning standards • The ACCE was contacted, and they responded to proposal to use a Delphi method affirmatively (“it is not our policy to comment on the assessment method used by programs…”
Task One: Selected representative work samples • Faculty were asked to identify which samples of student work they would use to evaluate students on each standard • Used as a source document
Accreditation standards listed Sources of evidence are listed
Task Two: Identify Strengths and Weaknesses in Student Performance • Faculty able to comment on each standard were then asked to look at the samples of student work they identified and make a list of strengths and weaknesses • Lists sent to analyst • There was fairly good compliance
Task Three: Analyze comments • Statements of strengths and weaknesses listed according to ACCE standard • Some statement combined if sufficiently the same • According to each standard, list is created. Those with like statements (coming from separate faculty) were identified as such; for example, after statement, “Students need to understand how to use accounting to submit bids better” (3 of you made this statement)
Task Four: Create survey • Each item on the list was assigned a five-point Liker-scale (5=strongly agree, 1=strongly disagree): Example Program Goal 1: The graduate will communicate effectively1. Graduating students need improvement in grammar. (3 of you gave this answer) 2. Graduating students need improvement in spelling. (3 of you gave this answer) …
Task Five: Collect and Analyze Information • Information inputted on SPSS and analyzed • Items with higher than 4.0, and standard deviation of less than 1.0 are declared “items of consensus”
Task Six: Report So Faculty Can Discuss and Make Recommendations • Results reported to faculty in a way that they can quickly use information • Graphical representations are often the best, where standard is listed next to assessment finding
Task Seven: List With Findings of Other Assessments to Discover Themes (Triangulate) • Perhaps more work than usual, but process can be very helpful, if not meaningful and potentially impactful
Results of Delphi assessment listed along with findings of other assessments
Final Thoughts • The “jury is still out” in respect to the use of the Delphi method as a direct assessment of student learning • Use of this method is a good method of adding specificity to portfolio assessments that identify student performance as “exceeds expectations;” we do not know what that means until we ask faculty evaluators to tell us what that means, or what issues derive from that judgment • Can be a method of inviting faculty to play an active part in both (1) assessment itself; and (2) discussing what recommendations should be made to enhance student performance
