Teachers have always engaged in analysis of each student's learning responses. The simplest and most common example is the teacher's evaluation of a student's answer as being either correct or incorrect. Teachers also plan subsequent activities based upon this analysis. This analytic approach adapts the instruction or practice to match the student's particular learning style or level of development. The analysis may be derived from a single response of a student in a teaching-learning situation or a synthesis of a number of observed behaviors of the student. This collection of case study materials is the product of a professional staff development project sponsored by two neighboring school districts. The concept of analytic teaching was developed to give teachers a comprehensive, widely applicable construct, which they could readily share. The accounts relate the teachers' approaches to analysis and adaptation with editor's comments regarding the teaching techniques used; the exploration of the student's abilities; and the use of analytic teaching.
