Chemical Misconceptions - Part 2

Chemistry is a conceptual subject and, in order to explain many of the concepts, teachers use models to describe the microscopic world and relate it to the macroscopic properties of matter. This can lead to problems, as a student's every-day experiences of the world and use of language can contradict the ideas put forward in chemical science. These titles have been designed to help tackle this issue of misconceptions.

The Royal Society of Chemistry have published two books Chemical Misconceptions: Prevention, Diagnosis and Cure Volumes I and II, which are designed to help tackle this issue of misconceptions. Used together, these two books will provide a good theoretical underpinning of the fundamentals of chemistry.

Part two provides strategies for dealing with some of the misconceptions that students have, by including ready to use classroom resources including copies of probes that can be used to identify ideas held by students; some specific exercises aimed at challenging some of the alternative ideas; and classroom activities that will help students to construct the chemical concepts required by the curriculum.

Resources

Mass and Dissolving

This resource, from the Royal Society of Chemistry, asks students to predict the masses of solutions from given masses of solute and solvent.

Students also need to explain what happens to the solute in solution and to explain the emergent properties of the solution. It is primarily aimed at the 11–14 age...

Ionisation Energy

This resource, from the Royal Society of Chemistry, covers ionisation energy, structure of the atom, intra-atomic forces. Students are provided with a diagram of the electronic structure of an atom and twenty statements which refer to it. They have to decide whether it each statement is correct or not.

Revising Acids

This resource, from the Royal Society of Chemistry, uses concept mapping to assess students' understanding of the topic of acids and bases.

This technique encourages active processing of information and improving study skills by getting students to think about their own learning. This exercise is designed...
