I have been reading Ausubel’s classroom assimilation theory (1978) from time to time as his theory has form the basis of the prevailing science education research especially in the area of concept maps.
Ausubel’s principle, “what the learner already knows” means that students come to the classroom with a prior understanding of science through their everyday experience, commom sense knowledge, etc. He further goes ahead and suggests that we as science educators need to ascertain this fact first and “teach the learner accordingly”.
Now that we are creating a network of pre-requisite concepts or a dependency network for a teaching sequence, we are claiming that there are certain concepts which the learner should understand first and then progressively learn the further depending concepts.
I am just trying to make connections with the depmap work and Ausubel’s principle.
People are welcome to create dependency network (depmap) atwww.gnowledge.org.
One can view some featured maps. A few sample of depmaps from physics, chemistry and biology are featured for providing a glimpse of the depmaps.
