SIMULATORS AS AN EDUCATIONAL RESOURCE TO ALTERNATIVE CONSIDERATIONS OF CHEMICAL EQUILIBRIUM IN STUDENTS AT UNIVERSITY LEVEL
In Chemistry teaching at University level, it has been detected that one of the most difficult concepts for the students to learn is, by far, chemical equilibrium. Chemical equilibrium is present in many chemical systems and helps to explain many associated phenomenologies. It is a concept whose teaching, therefore, should be strengthened to ensure that students could develop a deep comprehension of a wide range of chemical scenarios.
For that sake, in the present contribution it is proposed the use of chemical equilibrium-related ICT resources outside the classroom, by way of autonomous work of the student. Several ICT (simulators), available online for free, have been analysed based on how they develop the concept of chemical equilibrium through acid-base reactions, redox reactions, Le Chatelier's principle, etc. The authors believe that these programs can help to overcome some of the most frequent detected learning disabilities in chemistry. The implementation of this proposal is currently being done on Chemical grade students of the University of Alicante, in Spain.
