• Why do I get an error message when I submit the questionnaire?
  If you complete the questionnaire on-line and try to submit it and you get a message that the file cannot be found or the address is invalid, you're probably accessing an obsolete version. To get to the right one, go to
          http://www.ncsu.edu/felder-public/ILSpage.html
  select the web-based version of the instrument, complete and submit it. A form showing your learning styles profile should be returned immediately.

• How did the ILS originate, and what is its theoretical basis?
  The Index of Learning Styles was created in 1991 by Richard M. Felder, a chemical engineering professor at North Carolina State University, and Barbara A. Soloman, then the coordinator of advising for the N.C. State First-Year College. The four learning style dimensions of the instrument were adapted from a model developed in 1987 by Dr. Felder and Dr. Linda K. Silverman, an educational psychologist then at the University of Denver. The first version of the instrument was administered to several hundred students and the data were subjected to a factor analysis. Items that did not load heavily on one and only one item were replaced with new items to obtain the current 44-item version of the instrument. The ILS was installed on the World Wide Web in 1996. It gets close to a million hits per year and has been translated into Spanish, Portuguese, Italian, German, and several other languages.

• What is known about the reliability and validity of the ILS?
  Three studies have examined the independence, reliability, and construct validity of the four instrument scales. The authors conclude that the ILS meets standard acceptability criteria for instruments of its type.

• May I get the scoring key for the questionnaire and/or the code for the web-based version?
  The ILS is available at no cost to students and faculty at educational institutions to use for non-commercial purposes, and also to individuals who wish to determine their own learning styles. The commercial rights are held by North Carolina State University. While we have chosen to provide open access to the web-based instrument and so have voluntarily relinquished control over its use, we rely on the integrity of private sector users to help cover the expense of developing and maintaining it.
  If you are affiliated with an educational institution and wish to administer the ILS to your students, advisees, or educational research subjects, click here to access a certification form.
  If you are affiliated with an organization other than an educational institution or you are in business for yourself and wish to administer the ILS to your colleagues, employees, or clients, or if you are with an educational institution and wish to administer it to anyone other than students, advisees, or educational research subjects, please contact Mr. Warren G. Sasser of the N.C. State Technology Transfer Office, sasser@gw.fis.ncsu.edu, to purchase a license.

• May I administer the ILS to my pre-college students? If not, then what can I administer to them?
  The ILS was developed for use by college students and has only been validated for people of college age and older. Obviously, the instrument can only provide meaningful results for subjects who understand the questions: questions such as "When I solve math problems (a) I usually work my way to the solutions one step at a time; (b) I often just see the solutions but then have to struggle to figure out the steps to get to them," and "When I am learning a new subject, I prefer to (a) stay focused on that subject, learning as much about it as I can; (b) try to make connections between that subject and related subjects." Many older high school students might relate to those questions, but it would be a rare junior high school student and an even rarer elementary school student who could provide meaningful answers. In short, the younger the student, the less appropriate the ILS. If you're still interested in using it, you should scroll up to the response to the previous question.
  I know of two assessment instruments that are normally used for pre-college students. The first is the Dunn and Dunn Learning Style Inventory, which has a version designed for Grades 3 and 4 and another version for Grades 5-12. It can be obtained from Price Systems, Inc.. The second instrument is the Murphy-Meisgeier Type Inventory, which is designed to assess Myers-Briggs Type Indicator preferences for children in Grades 2-8 (ages 7-13). It can be obtained from the Center for Applications of Psychological Type and other organizations that distribute the MBTI.

• May I get copies of my students' profiles when they complete the questionnaire on the Web?
  Sorry--the questionnaire is not set up to do that. If you wish to collect responses, you will either have to ask the respondents to print out and hand in their profiles or make arrangements to secure the scoring key or the computer code for the instrument under the terms outlined in the previous question.

• What does it mean if I could have answered most of the questions either way?
  Imagine each dimension of the ILS as a two-pan scale, with each pan representing one of the two categories of the dimension (for example, sensing and intuiting), and weights in a pan representing skills associated with that category. If you have a preference for sensing, it means you have more weights in the sensing pan than the intuitive pan, and conversely if you have a preference for intuition.
  Some people have a strong preference for one category, say, sensing, over the other (they have many more weights in the sensing pan than in the intuitive pan). Those people will choose the sensing alternative on most of the 11 questions on the ILS that have to do with the sensing/intuitive dimension, and they will get a high score (9 or 11) for sensing. (The score is the difference between sensing responses and intuitive responses.) Others for whom the preference for sensing still exists but is not as strong will choose a few intuitive responses. They will get an intermediate score (5 or 7) for sensing.
  Still others who prefer sensing are closely balanced (nearly equal weights on both pans). In situations that call for behaving like a sensor or like an intuitor, they are almost equally likely to go either way. On the ILS, these individuals will end up choosing some sensing alternatives and almost as many intuitive alternatives and end up with a low score (1 or 3) for sensing. So, if you find that you have a hard time answering many questions that relate to a particular dimension, it just means that you are fairly well balanced on that dimension.
  It is important to remember that if you have a preference for one category it doesn't mean anything about how strong or weak you are at the other category (or at the first category, for that matter). One person with a preference for sensing may not be particularly skilled at either sensing or intuition (few weights in the sensing pan, even fewer in the intuitive pan). Another may have many skills in both categories (many weights in the intuitive pan, even more in the sensing pan). Both of these individuals would look alike on the ILS. Since people must function well in each category to be successful in work and in life, the goal for teachers should be to help equip students with both sensing skills and intuitive skills. For more information about how to do this, read "Reaching the Second Tier."

• Why isn't the inductive-deductive dimension of the original learning styles model assessed on the ILS?
  Since Linda Silverman and I developed the model on which the ILS is based, I have come to believe that while inductive and deductive are indeed different learning preferences and different teaching approaches, the "best" method of teaching--at least below the graduate school level--is inductive, whether it be called problem-based learning, discovery learning, inquiry learning, or some variation on the same theme. On the other hand, the traditional college teaching method is deductive, starting with "fundamentals" and then proceeding to applications.
  The problem with inductive presentation is that it isn't concise and prescriptive--you have to take a thorny problem or a collection of observations or data and try to make sense of it. Many or most students would say that they prefer deductive presentation, as in "Just tell me exactly what I need to know for the test, not one word more or less." Barbara Soloman and I don't want instructors to be able to give our instrument to students, find that the students prefer deductive presentation, and use that result to justify continuing to use the traditional deductive instructional paradigm in their courses and curricula. We have therefore omitted this dimension from the instrument.

• Why "visual-verbal" and not "visual-auditory-kinesthetic"?
  Visual and auditory learning both have to do with the component of the learning process in which information is perceived through the senses, while "kinesthetic" learning, being the only remaining category, lumps together both information perception (touching, tasting, smelling) and in­formation processing (moving, interacting with others, etc.). The perception-re­lated aspects of kinesthetic learning are at best marginally relevant to higher education and so are neglected in the learning styles model. The processing compo­nents of the kinesthetic modality are included in the active/reflective learn­ing style category. The next question addresses the verbal-auditory distinction.

• Since we see written words, why are they not included in the visual category?
  "Visual" information clearly includes pictures, diagrams, charts, plots, animations, etc., and “auditory” information clearly includes spoken words and other sounds. The one medium of information transmission that is not clear is written prose. It is perceived visually and so obviously cannot be categorized as auditory, but it is also a mistake to lump it into the visual category as though it were equivalent to a picture in transmitting information. Cognitive scientists have established that our brains generally convert written words into their spoken equivalents and process them in the same way that they process spoken words. Written words are therefore not equivalent to real visual information: to a visual learner, a picture is truly worth a thousand words, whether they are spoken or written. Making the learning style pair visual and verbal solves this problem by permitting spoken and written words to be included in the same category (verbal). For more details about the cognition studies that led to this conclusion, see
  R.M. Felder and E.R. Henriques, "Learning and Teaching Styles in Foreign and Second Language Education."

• Does anybody but me see the results when I submit the questionnaire?
  No. Your response data and your learning style profile are not stored or sent to anyone other than you and cannot be recovered once you have received the profile.
  Return to list of questions. 

• Is there a teaching styles inventory that parallels the ILS?
  None has been developed. If teachers look at the list of recommended teaching strategies in "Learning and Teaching Styles in Engineering Education," they should be able to judge the extent to which they are addressing the needs of students with different learning styles.
