“…The university guidelines for undergraduate computer science curricula from ACM and IEEE (2013) include the following topics, which we suggest for game-based learning in primary and secondary education and which have already been successfully implemented in games: basic principles of machine learning ( Wallace et al, 2008 ; Stöckl, 2019 ), algorithms and complexity ( Hong and Kung, 1981 ; Battistella et al, 2017 ), information theory ( Greeff et al, 2017 ), and computer architecture ( Tlili et al, 2016 ). In mathematics education, the majority of learning games focus on numbers and operations, algebra, geometry, measurement, and data analysis and probability ( Byun and Joung, 2018 ).…”
