The Study Technique Questionnaire was administered to 914 students in grades 6-8, in grades 10-12, and in undergraduate school. The students were asked to describe, in detail, their preferred study technique for a fairly long reading assignment. The responses were reliably grouped into one of nine categories: read only; read and underline; read and take notes; read, underline, and take notes; read and underline or take notes; read and underline, take notes, or outline; read and outline; read and outline or underline; and read and form mental notes. Reading only was the most popular technique for 60% of the sixth-eighth grade students, 47% of tenth through twelfth graders, and 13% of undergraduate students. Reading and underlining was the first choice of 39% of the college students. The popularity of underlining and of note taking (combined with reading) greatly increased with increasing student age. The variety of techniques described also increased for older age groups. This variety may be explained by the increased level of student participation which is demanded by the more complex reading material, or by the fact that individual aptitudes, characteristics, and habits are more firmly established in older students.
