An understanding of the effect of environment on
phyllochron (degree-days between two successive leaves) is
necessary to model cereal crop canopy growth. This study
was designed to investigate the relationships of phyllochron
to temperatures and daylengths in winter wheat (Triticum
aestivum L.) and spring barley (Hordeum vulgare L.). A
series...
Generalization is a fundamental mathematical practice across all disciplines and content areas (Amit & Klass, 2005; Lannin, 2005; Pierce, 1902; Vygotsky, 1986; Ellis, Lockwood, Tillema & Moore, 2017). While a considerable amount of research has been conducted on students' generalizing activity in algebraic contexts (Amit & Klass 2005; Becker &...
Enumerative combinatorics is an area of mathematics that is both highly accessible for students and widely applicable to other sciences and areas of mathematics (Kapur, 1970; Lockwood, Wasserman, & Tillema, 2020). One important class of problems in combinatorics is combinatorial proofs of binomial identities, which is a type of proof...
