This chapter outlines the Planning Tool for Implementing Critical Global Learning, which is the second component of the conceptual framework. The aim of the Planning Tool is to provide a systematic approach to teaching which offers space and opportunity to students to learn and to develop critical thinking skills, while still honouring students’ voices, experiences, and opinions without compromising the core values of social justice and human rights. The Planning Tool is presented visually as a funnel and includes three main components: the necessary pre-conditions for learning which scaffold student learning, the lesson elements which include both what happens in the classroom, and how, and the anticipated outcomes which ensure a focus on the purpose and impact of teaching and learning. This chapter will outline in further detail the rationale and purpose of the Planning Tool, as well as detailed descriptions of each of its components. In sharing the components of the tool, this chapter will also focus on the theoretical foundations and origins of each component. Furthermore, as this tool is practical in nature, this chapter will include many practical examples of how the tool can, and has, been used in practice.
