Some criticisms of high school have been concerned with what organizational theorists call operations technology. Broadly, technology refers to the work an individual teacher or the school's collective professional staff does with or for students, the school's "raw material." Technology can be studied more closely by separation into three aspects--operations, materials, and knowledge--with each aspect potentially distinguished by classroom-level and school-level attributes. The National Institute of Education/National Association of Secondary School Principals Survey of Public Secondary School Principals applies primarily to operations technology and a few indicators of materials technology. Overall, no clear pattern emerged enabling one to identify schools with a generally complex operations technology or schools with simpler operations technology. This absence of a unifying construct should be recognized as the analysis of the survey proceeds. While limited in their applicability to the most complex practices within schools, the results of the survey lay the groundwork for intensive research into classroom-level technological complexity and elaboration of the concepts of technology at the school level.
