Description:
We discuss how to reduce the incongruence between outcomes (both cognitive and affective) of conventional secondary chemistry curriculum and what is to be attained: the meaningful connection of students' learning to daily life and societal issues. This problem is addressed by a design study with one curriculum unit about 'Water Quality'. With several research cycles using developmental research, we developed an emergent understanding about an instructional framework for curriculum units that embodies a coherent 'need-to-know' principle and is based on authentic practices. Using this framework we show with some other examples how a context-based chemistry curriculum can be constructed on basis of the developed ‘need-to-know’ principle.
