Learning outcomes for participants/users and, where relevant, pupils or students

Our courses are designed to give you an in-depth understanding of key concepts in teaching chemistry. Each course can be completed at your own pace, giving you time to try out new strategies and activities in your classroom before progressing further. The course will allow you to learn about the key concepts in that area and access ideas and resources to enhance your classroom teaching.

Redox reactions take us down an important conceptual pathway in chemistry. Our understanding of redox begins with the gain and loss of oxygen and develops into the gain and loss of hydrogen. This paves the way to understanding all chemical reactions as a rearrangement of electrons. Ions are examined and in the reactivity series we see metals ranked into an ‘order of reactivity’ compared to each other. We use oxidation numbers as a useful system of electron accounting to help us identify when electron transfer has taken place. We use half equations to summarise and communicate those electron transfers. Electrolysis involves the forced transfer of electrons by an applied voltage. Electrode potentials use the generated voltage from separated half reactions to predict the feasibility of reactions. Finally, we see how the electrochemical series gives us quantitative data which surpasses the qualitative reactivity series.

After working through this course you will be able to:

  • understand the core ideas about redox;
  • explain how the conventions we use like oxidation number and electrode potentials work;
  • anticipate common misconceptions that arise and adapt your teaching to minimise these;
  • confidently deliver key experiments, demonstrations and activities that develop student understanding; and
  • access a wider range of activities and resources to support students' learning about redox reactions.
Evidence underpinning this approach

Teaching redox chemistry is crucial to students' understanding of chemistry as a whole. Redox chemistry gives a context in which students develop an understanding of chemical reactions - from rearranging atoms to rearranging electrons. This course explores how to base teaching on fundamental understanding rather than on simple application of conventions to topics such as oxidation numbers and electrode potentials. Moreover, typical chemistry teachers problems and students misconceptions will be discussed.

How users/participants can evaluate success

Learning outcomes have been designed by highly qualified course authors, in conjunction with the Royal Society of Chemistry, with the target audience in mind. The course content has been written to achieve the learning outcomes and there are opportunities for self-assessment included within the course.

Within the course there is a course development plan that can be used to stipulate aims and impact. It also includes space to reflect on these at the end of the course.

Follow-up activities and support

The course includes links to articles and resources to support lesson planning for teaching the topic, following the course.


This online course allows participants to access the material remotely. This is particularly useful for teachers, as it means that they need less time away from the classroom, as there is no travel involved. There is also a cost reduction because of this, including travel and cover for teaching time. The participant can work through the material at their own pace and there is the functionality to dip in and out of the material.

This course does not have any pre-booked dates available. Please contact the provider directly to arrange this training.
