Description

The report argues that instructional time policy must build in realistic room for the human and operational demands of elementary classrooms rather than a maximally compressed schedule. Its observations showed schools operating "a highly compressed schedule" in which non-instructional demands spill into officially allotted instruction time. It concludes that a 300-minutes-a-day instructional program must be nested within a school day of 360-400 minutes, depending on lunch organization and whether recess is restored.

Design Implications

Context

Requirements

• School day length must be extended beyond the current 330-minute closed campus schedule to absorb operational demands without eroding instruction.

Constraints

• The report notes Chicago's largely disadvantaged schools are asked to make achievement gains in less time than more advantaged surrounding systems; new charter schools chose 60-90 minutes longer days.

Target Learners

• Chicago Public Schools elementary students

Learning Goals

• Increasing delivered instructional time across the full academic program

Claims

• 300 Minutes Requires 360 400 Minute Day [+M]
• Management Reduces Daily Instruction 240 Minutes [+M]
