How can acid-base simulations be of help? Detection of learning difficulties and possible teaching sequences
Keywords:
chemistry teaching, acid-base titrations, simulations, sequenceAbstract
This paper discusses certain issues related to the use of simulations in the teaching of acid-base titrations topic. It also shows results of two activities carried out with first year university students: (1) alternative evaluation of acid-base titrations topic through a simulation and (2) reformulation actvity of a problem or verification of the results of a simulation. In order to overcome the observed difficulties a third activity was carried on consisting of: (3) selection of simulations and creation of a teaching sequence for the acid-base titration topic.
