Modeling Person-Specific Development of Math Skills in Continuous Time: New Evidence for Mutualism.
International Educational Data Mining Society, 2019•ERIC
In this study, we fitted a mixed-effects nonlinear continuous-time mutualism model of skill
development proposed by van der Maas et al.(2006) to naturally collected irregularly spaced
time series data from an online adaptive practice system for mathematics called Math
Garden. Results showed that the mutualism model provided a better fit to the data than a g-
factor model. The paper illustrates continuous-time modeling of irregularly-spaced
multivariate time series data that are increasingly prevalent in modern learning systems.[For …
