RAVIOLO, Andrés  and  FARRE, Andrea. An alternative evaluation of acid-base titrations through a simulation. Educ. quím [online]. 2017, vol.28, n.3, pp.163-173. ISSN 0187-893X.  https://doi.org/10.1016/j.eq.2017.01.003.

This work shows the results of a learning experience on acid-base titrations, based on the projection of a simulation, in the context of an integrating and conceptual final evaluation. This activity was done after the first year university students attended theoretical, problem-solving and lab lessons and were subjected to traditional evaluation. Students were inquired about how they had identified the different materials and entities shown in the simulation and how they had established adequate conceptual links between them. In order to evaluate the results, the sample was divided in two groups depending on whether the participants had approved or not the General Chemistry mid-term evaluation. Interesting conclusions came up about what happens when students have to draw information from a simulation to solve traditional format problems.

Keywords : Alternative evaluation; Simulation; Acid-base titration.
