Curriculuar differentiation enables the teacher to interpret student profile information, and pre-assessment/formative assessment results to apply curriculum differentiation decisions. Using baseline information to gauge best adjustments to hit learning targets, the teacher matches appropriate curriculum materials, instructional approaches, assessment tools, and/or products that evidence learning.
Curricular differentiation is the teacher's plan to accomodate the specific learning needs for an individual student and/or flexible groups of students with similar needs at any given time. Curricular modifications teachers typically consider include curriculum materials to accomodate readiness, reading level, student interest(s), curriculum process variations, curriculum learning targets (scaffolded, perhaps), balanced assessment pratices, etc.
