Addressing The Stem Challenge Through Targeted Teaching : What’S The Evidence?, Dianne Siemon

2009 - 2019 ACER Research Conferences

Numerous public reports are pointing to the critical importance of STEM (science, technology, engineering and mathematics) to Australia’s future, but the number of students studying STEM subjects in senior years is declining, and many students in the primary and middle years of schooling do not have access to the ways of thinking and learning needed to succeed in school mathematics. Research over the past 10 years has established the critical role of multiplicative thinking in building student knowledge and confidence at this level of schooling, but there is a need for an expanded, evidence-based learning and teaching framework to support …

Paper 1: Analysis Of Achievement For Understanding Geometry, Linda Nash, Annita Hunt, Denise Huddlestun, Kelli Nipper

Georgia Association of Mathematics Teacher Educators (GAMTE) Annual Conference

The purpose of this study was to investigate the effectiveness of a mathematics professional development course. More specifically, in this study we examine whether geometric experiences have an impact on level of performance in mathematics. The van Hiele (Fuys, D., Geddes, D., & Tischler, R., 1988) model of geometric understanding provided a research framework from which to view geometric understanding. This model suggests five levels of understanding that should be taken into consideration when examining levels of geometric thinking: Visual, Descriptive/Analytic, Abstract/Relational, Formal Deduction/Proof, and Rigor.

The sample under study was three cohorts of practicing elementary teachers and mathematics coaches …
