Taxonomy Category	BCT	Definition	Example
Shaping knowledge	1. Instruction on how to perform the behaviour	Advise or agree on how to perform the behaviour (includes skills training)	Training at workshop provides information/modelling on how to perform movement integration. Website provides resources/instruction to support implementation.
Natural consequences	2. Information about health/education outcomes/consequences	Provide information about health outcomes/consequences of performing the wanted/unwanted behaviour	Workshop and website provide information on the health disbenefits of prolonged sitting and the benefits of active learning to education and health outcomes.
Antecedents	3. Restructuring the physical environment	To change the physical environment in order to facilitate the performance of the wanted behaviour	Teachers advised in workshop on how to arrange classroom to allow space for movement.
Comparison of behaviour	4. Information about others’ approval	Provide information about what other people think of the behaviour	Videos of teachers’ and pupils’ views from the pilot phase of the project shared with teachers through the website. Teachers from the pilot phase also attending the workshop to share views of implementing movement integration.
Comparison of outcomes	5. Credible source	Present verbal or visual information from a credible source in favour of the behaviour	Peer-reviewed published research on movement integration shared in workshop and on website.
Goals and planning	6. Problem solving	Analyse or prompt the person to analyse factors influencing the behaviour and generate or select strategies that include overcoming barriers and/or increasing facilitators	Teachers prompted to discuss barriers/facilitators to movement integration and to identify solutions.
Feedback and monitoring	7. Enablement	Self-monitoring of behaviour	Teachers asked to keep a log (online or paper/pencil version if preferred) of movement integration delivery including date, time, activity type, resource(s) used, duration of activity and pupil engagement.
Repetition and substitution	8. Behaviour substitution	Prompt substitution of unwanted behaviour with a wanted behaviour	Teachers encouraged at the workshop to implement movement integration to replace previously sedentary time/teaching practices.
Goals and planning	9. Goal setting	Set or agree on a goal defined in terms of the behaviour to be achieved	Teachers complete pledge postcard, with three movement integration goals. To be mailed back to teacher 6 weeks post-workshop by another attendee.
