**COMPUTATIONAL MODELLING**

This eBook is about modelling with code, a.k.a. computational modelling, in the context of teaching and learning mathematics.

More activities will be added on a regular basis: this eBook is a work in progress.

**Computation in our society**

Our societies are growing in complexity, in large part because of the intertwining connections afforded by new technologies. The use of computational tools to model phenomena, processes and relationships is becoming a prerequisite to scientific progress and economic success, as evidenced by the emergence of numerous computational modelling fields, such as computational biology, computational mathematics, computational finance, computational medicine, to name a few examples.

The authentic *computational modelling *practices of scientists and professionals involve solving real-world problems and build knowledge – to learn – through computational “conversation” and “interaction” with their field (Barba, 2014) “with and across a variety of representational technologies” (Wilkerson-Jerde, Gravel and Macrander, 2015, p. 396).

“It’s a source of power to *do *something and figure things out, in a dance between the computer and our thoughts. The inversion, starting with computing as a formal thing to understand and then come to the application later, takes away its power.” (Barba, 2016)

**Computational modelling in mathematics education**

A focus on computational modelling in education, which is not isolated but integrated with mathematics (and with other subjects), not only prepares students for future success; it also provides students a powerful learning tool with which to design, test and refine conceptual schema and build powerful understandings of mathematics they are studying.

**Mathematics education reform**

The table below illustrates how computational affordances may map onto mathematics education reform goals (Gadanidis, 2017; Gadanidis, Clements & Yiu, 2018).
