<Li> Physiological styles are bodily states or predispositions, including sex - related differences, health and nutrition, and reaction to physical surroundings, such as preferences for levels of light, sound, and temperature . </Li> <P> According to the NASSP task force, styles are hypothetical constructs that help to explain the learning (and teaching) process . They posited that one can recognize the learning style of an individual student by observing his or her behavior . Learning has taken place only when one observes a relatively stable change in learner behavior resulting from what has been experienced . </P> <P> The Learning Style Inventory (LSI) is connected with David A. Kolb's model and is used to determine a student's learning style . Previous versions of the LSI have been criticized for problems with validity, reliability, and other issues . Version 4 of the Learning Style Inventory replaces the four learning styles of previous versions with nine new learning styles: initiating, experiencing, imagining, reflecting, analyzing, thinking, deciding, acting, and balancing . The LSI is intended to help employees or students "understand how their learning style impacts upon problem solving, teamwork, handling conflict, communication and career choice; develop more learning flexibility; find out why teams work well--or badly--together; strengthen their overall learning ." </P> <P> A completely different Learning Styles Inventory is associated with a binary division of learning styles, developed by Richard Felder and Linda Silverman . In Felder and Silverman's model, learning styles are a balance between pairs of extremes such as: Active / Reflective, Sensing / Intuitive, Verbal / Visual, and Sequential / Global . Students receive four scores describing these balances . Like the LSI mentioned above, this inventory provides overviews and synopses for teachers . </P>
