Determine whether the classroom has a largely introverted or extroverted personality type. Have students gather in a circle. Give the class a speaking prompt and have each student answer individually. Make note of students who willingly participate. For those visibly uncomfortable with the task, suggest writing down responses and reading them. According to the Meyer-Briggs Type Indicator, "students with a preference for Extraversion need action and interaction to learn. Students with a preference for Introversion learn best when they have time for reflection."
Perform a Meyer-Briggs personality test within the classroom. Although it is meant as a "guide," the test may allow you to understand the basic personality breakdown of a classroom unit. A Meyer-Briggs test is based upon the idea that there are "four primary ways people differed from one another," which are sensing vs. intuition and thinking vs. feeling. The test will provide the basic personality breakdown of your students.
Allow students to decide whether a project will be done in groups or individually. Create a ballot for students to vote without feeling peer pressure; based upon the results, create a project that fits the personality type of the majority of students. If the classroom decides upon a group project, they are likely extroverted in the majority. However, if students choose individual projects, introversion is most likely the dominant personality type.
Test different learning styles within the classroom. According to Arthur J. More, an educational researcher, "Learning styles are the mental processes and instructional settings a student uses most effectively during learning." More notes the five major learning styles: global/analytic, verbal/imaginal, concrete/abstract, TEF/reflective and modality. Each learning type is listed with its opposite. More states that instructors should identify individual styles, "match teaching styles for difficult learning tasks," employ more difficult learning styles with easier material, and finally teach "selection strategies" so students can employ different learning styles on their own.
