Presenters: Dawn Teuscher and Porter Nielsen, Brigham Young University Location: NCTM 2019 Regional Conference & Exposition in Salt Lake City, Utah Abstract/Description: This session will examine the relationships among the three geometric transformations-reflections, translations and rotations. We will also examine how the sequence of transformations can be used to connect the three transformations. Finally, we will discuss how understanding these relationships will help students make sense of transformations.
Presenters: Porter Nielsen, Brigham Young University Location: NCTM 2019 Regional Conference in Salt Lake City, Utah Abstract/Description: In order to leverage the power behind the mathematical definition of reflections as a transformation, we examine how curriculum, teacher decisions, and student interpretations of reflections relate to one another.
Presenters: Dawn Teuscher, Brigham Young University and Porter Nielsen, Brigham Young University Location: SSMA 2019 Convention, Salt Lake City, Utah Abstract/Description: Curricular reasoning (CR) is the thinking processes that teachers use to make decisions (e.g., what content to teach, the tasks to facilitate student learning). In this presentation, we outline five CR aspects gleaned from research with middle grades mathematics teachers as they planned and implemented instruction with unfamiliar curriculum.
