Incorporating The Dragging Feature Of Dynamic Geometry Environments In Teaching And Learning College Geometry, Tuyin An, Ha Nguyen

Proceedings of the Interdisciplinary STEM Teaching & Learning Conference (Archived)

In a study about pre-service secondary mathematics teachers’ (PSMTs) understanding about the nature of theorems in geometry, the researcher noticed that it was challenging for the PSMTs to visualize and draw counterexamples to disprove the given mathematical statements. Meanwhile, the use of the dragging feature of dynamic geometry environments (DGEs), such as the Geometer’s Sketchpad and GeoGebra, in teaching and learning proof and reasoning has been widely discussed and become an ongoing research trend. In this paper, the researcher and her colleague will present a research design aimed at investigating PSMTs’ conceptions of counterexamples in geometric reasoning when using the …

Using Cartoons To Make Connections And Enrich Mathematics, Janet St. Clair

Proceedings of the Interdisciplinary STEM Teaching & Learning Conference (Archived)

The article discusses the integration of cartoons into a finite mathematics college course. However, cartoon integration is appropriate for any educational level STEM course.

Short-ranged correlated (SRC) nucleon-nucleon (NN) pairs account for about 20% of all nucleons in medium to heavy nuclei and about 75% of the nuclear kinetic energy. In addition, there is strong evidence linking these pairs to nucleon structure modification in nuclei (the EMC effect). A Significant amount of our knowledge of SRC pairs comes from hard two nucleon knockout measurements, conducted using electron (i.e. (e e'pp) and (e,e'pn)) and proton probes (i.e. (p, 2pn)). These studies show that almost all high-momentum nucleons belong to SRC pairs, that these pairs are predominantly pn pairs …
