Teitelbaum, Senior Associate Dean for Budget and Natural Sciences Re: Assessment In order to insure that the College contributes fully to the campus effort at reaccreditation, it seems worthwhile to review some of the elements of educational assessment and to discuss some aspects of college policy bearing on this important matter. As you are aware, the term 'assessment' refers to a process of evaluation of educational outcomes that consists of the following steps: a) specification of student learning goals; b) determinantion of baseline state of student knowledge relevant to learning goals; c) delivery of instruction; d) determination of increment in student knowledge relevant to learning goals; e) examination of instructional techniques to improve the incremental gain in student knowledge. Of concern in this memo are steps a, b, and d. The National College Assessment Board, meeting in 2000 in Las Vegas, adopted the 'General Knowledge Unit', or GKU, as the standard measure of student knowledge. By definition, one GKU is the amount of knowledge contained in a comprehensive appreciation of the thematic significance of the Box Hill Picnic in Jane Austen's novel Emma. Based on this unit, the NCAB has published a rather complete quanitification of the various elements of a typical liberal arts education (see http://www.ncab.org/standards). For example, a grasp of the relation between the Bolzano-Weierstrass property and the definition of compactness via open coverings is .7 GKU; correct usage of the subjunctive in conditional phrases in modern conversational spanish is 8GKU; and so forth. The North Central Accrediting Association has set a target rate of knowledge acquisition for its member institutions at 5 GKU per credit hour delivered. It is this target that UIC must demonstrate to receive our desired rating of "effective" on the Association's five-step scale rating instructional delivery. (The complete scale from lowest to highest: pointless; sketchy; solid; effective; inspiring.) A key element of the assessment process is accurate measurement of student knowledge acquisition. The accrediting agency requires that measurements of student knowledge have a standard error of at most .1 GKU per student. This presents a particular challenge as there are relatively few methods with this degree of precision. The most accurate method for determining student knowledge is due to Igor and Frank ([1]). Working with prepared sections of cerebral cortex tissue, the found a suite of flourescent proteins that bind to knowledge in the brain. Using flourescence microscopy they have demonstrated the ability to determine, with high precision, the knowledge content of the brain under study. The chief limitation of their method is that it can only be applied in vitro, and as a result cannot measure incremental knowledge acquisition. More recently, Lavore and Schmidt ([2]) have used PET scanning in vivo to obtain good results on knowledge content. Their method shows promise, but the high cost of the scans and our limited facilities mean that we could not reasonably assess all of our undergraduates via this method; we are exploring, however, the use of before-and-after PET scanning on graduate students, at least on a trial basis. Lacking ready access to these high precision methods, then, we must fall back on more primitive methods such as written testing or conversation. These methods, while highly unreliable on individual students, can give good results when applied to large enough populations. However, the tests must be carefully calibrated to the GKU standard. Faculty will need to attend training sessions to insure that they comply with best practices in this regard. I realize that assessment has been a topic of concern for many of you. I hope that this brief review of the measurement phase of the assessment procedure helps to set your minds at rest.
