Sign Up to like & getrecommendations! Published in 2018 at "Journal of Mathematical Biology"
DOI: 10.1007/s00285-017-1167-9
Abstract: A time-tree is a rooted phylogenetic tree such that all internal nodes are equipped with absolute divergence dates and all leaf nodes are equipped with sampling dates. Such time-trees have become a central object of… read more here.

To add or to multiply in open problems? Unraveling children’s relational preference using a mixed-method approach
Sign Up to like & getrecommendations! Published in 2020 at "Educational Studies in Mathematics"
DOI: 10.1007/s10649-020-09966-z
Abstract: Previous research demonstrated that some children inappropriately solve multiplicative missing-value word problems additively, while others inappropriately solve additive missing-value word problems multiplicatively. Besides lacking skills, children’s preference for additive or multiplicative relations has been shown… read more here.
