Working memory is defined as a cognitive system that holds information temporarily and has a limited capacity. Working memory is considered to be important for reasoning and decision making and also controlling behaviour. In education, working memory is something often talked about by teachers when they notice students struggling with processing or retaining information in the classroom.
Baddeley (1974) developed a working model that established that working memory is distinct from long term memory and not only does it deal with retaining information but also processes the information to develop cognition.
