Backward design is a fancy term for a popular learner assessment strategy.
Simply put, instead of teaching and then assessing, core learning outcomes or success criteria are identified and assessment is written to meet the outcomes.
A teacher or course developer then designs the lessons that enable the student to successfully complete the assessment and achieve the learning outcomes or success criteria. Jump Ahead uses backward design in most English, Maths and Science activities.
