Theory as foundation
The importance of theory in Mathematics as a tool to ensure
learners can solve complex problems.
Presented by Sarel van Greunen
AKA Mr vG
Theory, oh theory, why should my time be wasted upon thee?
 Million dollar question:
Applied vs Pure Mathematics
 Article written by Jeroen Strijbosch:
Applied vs. Pure Math  How we (Should) Design Math Education
 Study done in 2016 by Organization for Economic Cooperation and Development (OECD)
about students writing the PISA test.
 Written by students from 94 countries.
 Excerpt from article:
Andreas Schleicher, director of the education and skills department at the
OECD, explained it thusly: Our analysis is [that] when students have really understood the
foundations, they can extrapolate. They can apply that knowledge in another
context. However, if they only teach students tips and tricks, how to solve small everyday
problems, they know how to solve those problems, but theyre not good at transferring
that knowledge to another context.

forever changed.
