Abstract: Compilation and settings of science problems in science teaching materials requires the devel-opment and exploration.In the enlightenment of original problem,structure of science problem is de-fined as overlapping and conflict with conceptual ecology and situational ecology.Based on this,taking conceptual ecology as the abscissa and situational ecology as the ordinate,we constructed the science problem classification coordinate system.In the classification coordinate system,prominence is given to the location and nature of different types of questions.Application and prospect of classification co-ordinate include the enlightenment of science problem structure to compilation and teaching of science problems,enhancement of the original science questions in the science teaching material system and the display of the function of measurement of the science problem classification coordinate system.
