A '''concept inventory''' is a [[criterion-referenced test]] designed to help determine whether a student has an accurate working [[knowledge]] of a specific set of concepts. Historically, concept inventories have been in the form of [[multiple-choice test]]s in order to aid interpretability and facilitate administration in large classes. Unlike a typical, teacher-authored multiple-choice test, questions and response choices on concept inventories are the subject of extensive research. The aims of the research include ascertaining (a) the range of what individuals think a particular question is asking and (b) the most common responses to the questions. Concept inventories are evaluated to ensure test [[reliability (statistics)|reliability]] and [[validity (statistics)|validity]]. In its final form, each question includes one correct answer and several distractors.

Ideally, a score on a criterion-referenced test reflects the amount of content knowledge a student has mastered. Criterion-referenced tests differ from [[norm-referenced tests]] in that (in theory) the former is not used to compare an individual's score to the scores of the group. Ordinarily, the purpose of a criterion-referenced test is to ascertain whether a student mastered a predetermined amount of content knowledge; upon obtaining a test score that is at or above a [[cutscore|cutoff score]], the student can move on to study a body of content knowledge that follows next in a learning sequence. In general, item difficulty values ranging between 30% and 70% are best able to provide information about student understanding.

The distractors are incorrect or irrelevant answers that are usually (but not always) based on students' commonly held misconceptions.<ref>"Development and Validation of Instruments to Measure Learning of Expert-Like Thinking." W. K. Adams & C. E. Wieman, 2010. International Journal of Science Education, 1-24. iFirst, {{doi|10.1080/09500693.2010.512369}}</ref> Test developers often research student misconceptions by examining students' responses to open-ended essay questions and conducting "think-aloud" interviews with students. The distractors chosen by students help researchers understand student thinking and give instructors insights into students' prior knowledge (and, sometimes, firmly held beliefs). This foundation in research underlies instrument construction and design, and plays a role in helping educators obtain clues about students' ideas, [[scientific misconceptions]], and [[didaskalogenic]] ("teacher-induced" or "teaching-induced") confusions and conceptual lacunae that interfere with learning.

==Concept inventories in use==
Concept inventories are education-related diagnostic tests.<ref>ref name=Tregust, 1988">Tregust, D.F. 1988. Development and use of diagnostic tests to evaluate students' misconceptions in science. International Journal of Science Education 10: 159-169 [http://www.tandfonline.com/doi/abs/10.1080/0950069880100204#.VKMeQsZl5FI]</ref> In 1985 Halloun and Hestenes introduced a "multiple-choice mechanics diagnostic test" to examine students' concepts about motion.<ref name="Halloun and Hestenes">Hallouin, I. A., & Hestenes, D. Common sense concepts about motion (1985). American Journal of Physics, 53, 1043-1055</ref> It evaluates student understanding of basic concepts in classical (macroscopic) mechanics. A little later, the [[Force Concept Inventory]] (FCI), another concept inventory, was developed.<ref name="Halloun and Hestenes"/><ref>Hestenes D, Wells M, Swackhamer G 1992 Force concept inventory. The Physics Teacher 30: 141-166.</ref><ref>[http://scitation.aip.org/vsearch/servlet/VerityServlet?KEY=AJPIAS&CURRENT=NO&ONLINE=YES&smode=strresults&sort=rel&maxdisp=25&threshold=0&pjournals=AJPIAS&pyears=2001%2C2000%2C1999&possible1=465&possible1zone=fpage&fromvolume=66&SMODE=strsearch&OUTLOG=NO&viewabs=AJPIAS&key=DISPLAY&docID=1&page=1&chapter=0 Hestenes D 1998. Am. J. Phys. 66:465]</ref> The FCI was designed to assess student understanding of the [[Classical mechanics|Newtonian]] concepts of force. Hestenes (1998) found that while "nearly 80% of the [students completing introductory college physics courses] could state [[Newton's laws of motion|Newton's Third Law]] at the beginning of the course. FCI data showed that less than 15% of them fully understood it at the end".These results have been replicated in a number of studies involving students at a range of institutions (see sources section below). That said, there remains questions as what exactly the FCI measures.<ref name="Huffman">Huffman, D. & P. Heller. 1995. What does the force concept inventory actually measure? The Physics Teacher 33: 138-143; Heller, P. & D. Huffman. 1995.[http://www.physics.emory.edu/faculty/weeks//journal/hestenes-tpt95c.pdf]</ref> Results from Hake (1998) using the FCI have led to greater recognition in the [[science education]] community of the importance of students' "interactive engagement" with the materials to be mastered.<ref name="Hake">Hake, R.

In many areas, foundational scientific concepts transcend disciplinary boundaries. An example of an inventory that assesses knowledge of such concepts is an instrument developed by Odom and Barrow (1995) to evaluate understanding of [[diffusion]] and [[osmosis]].<ref name="Odom">Odom AL, Barrow LH 1995 Development and application of a two-tier diagnostic test measuring college biology students' understanding of diffusion and osmosis after a course of instruction. Journal of Research In Science Teaching 32: 45-61.</ref> In addition, there are non-multiple choice conceptual instruments, such as the essay-based approach suggested by Wright et al. (1998)<ref name="Wright">[http://bioliteracy.colorado.edu/Readings/Wright.pdf Wright et al., 1998. J. Chem. Ed. 75: 986-992]</ref> and the essay and oral exams used by Nehm and Schonfeld (2008).<ref name="Nehm & Schonfeld 2008"/> and Cooper et al <ref>Cooper, M. M.; Underwood, S. M.; Hilley, C. Z., 2012.

Pract. 13, 195-200.[http://pubs.rsc.org/en/content/articlehtml/2012/rp/c2rp00010e]</ref> to measure student understanding of Lewis structures in chemistry.

==Caveats associated with concept inventory use==
Some concept inventories are problematic. The concepts tested may not be fundamental or important in a particular discipline, the concepts involved may not be explicitly taught in a class or curriculum, or answering a question correctly may require only a superficial understanding of a topic. It is therefore possible to either over-estimate or under-estimate student content mastery. While concept inventories designed to identify trends in student thinking may not useful in monitoring learning gains as a result of pedagogical interventions, while disciplinary mastery may not be the variable measure by a particular instrument. Users should be careful to ensure that concept inventories are actually testing conceptual understanding, rather than test-taking ability, language skills, or other abilities that can influence test performance.

The use of multiple-choice exams as concept inventories is not without controversy. The very structure of multiple-choice type concept inventories raises questions involving the extent to which complex, and often nuanced situations and ideas must be simplified or clarified to produce unambiguous responses. For example, a multiple-choice exam designed to assess knowledge of key concepts in natural selection<ref name="AFN"/> does not meet a number of standards of quality control.<ref name="Nehm & Schonfeld 2010"/> One problem with the exam is that the two members of each of several pairs of parallel items, with each pair designed to measure exactly one key concept in natural selection, sometimes have very different levels of difficulty.<ref name="Nehm & Schonfeld 2008"/> Another problem is that the multiple-choice exam overestimates knowledge of natural selection as reflected in student performance on a diagnostic essay exam and a diagnostic oral exam, two instruments with reasonably good [[construct validity]].<ref name="Nehm & Schonfeld 2008"/> Although scoring concept inventories in the form of essay or oral exams is labor-intensive, costly, and difficult to implement with large numbers of students, such exams can offer a more realistic appraisal of the actual levels of students' conceptual mastery as well as their misconceptions.<ref name="Wright"/><ref name="Nehm & Schonfeld 2008"/> Recently, however, computer technology has been developed that can [[Automated essay scoring|score essay responses]] on concept inventories in biology and other domains (Nehm, Ha, & Mayfield, 2011),<ref>Nehm, R.H., Ha, M., Mayfield, E. (in press). Transforming Biology Assessment with Machine Learning: Automated Scoring of Written Evolutionary Explanations. Journal of Science Education and Technology. [http://www.springerlink.com/content/1059-0145/preprint/?sort=p_OnlineDate&sortorder=desc&o=30]</ref> promising to facilitate the scoring of concept inventories organized as (transcribed) oral exams as well as essays.
