Translanguaging is a view around languages that normalizes diglossia without separation: the linguistic resources of the bilinguals are considered one integrated system. Translanguaging is also a language practice of bilinguals, who select features from their entire linguistic repertoire to make sense of the world around them. Translanguaging is widely used by students and teachers in the bilingual classroom, as it allows students to build upon their entire set of resources, enhance learning outcomes, perform identities, and develop their languages even further. However, translanguaging is rarely used in assessments of bilinguals. Assessments of bilinguals, especially large-scale tests, are typically monolingual in …

Cross Case Study Of An Elementary Engineering Task, John Heffernan Jul 2017

Cross Case Study Of An Elementary Engineering Task, John Heffernan

Doctoral Dissertations

Designerly play has been identified as a fundamental component of childhood learning (Baynes, 1994; Petroski, 2003). However, as students enter grade one and beyond, the increasing academic focus has resulted in the loss of opportunities for designerly play (Zhao, 2012). At the same time, there are increasing calls to increase the number, skill, and diversity of STEM workers (Brophy, Portsmore, Klein, & Rogers, 2008). The robotics based Elementary Engineering Curriculum (Heffernan, 2013) - used by students in this study - and other similar projects have the potential to increase the STEM pipeline but elementary engineering is not well-understood. Research is …

Supporting Black And Brown Females’ Stem Identity Construction Through Mathematics Teacher Noticing: A Mixed Methods Study, Carolyn Gardner Jul 2017

Supporting Black And Brown Females’ Stem Identity Construction Through Mathematics Teacher Noticing: A Mixed Methods Study, Carolyn Gardner

Doctoral Dissertations

The current study explores the nature of the relationship between a teacher’s experiences and her pedagogical practices that are oriented to support female students of color identity construction in relation to science, technology, engineering and mathematics (STEM) studies and careers. The narratives and class observations of the female mathematics teacher of color who is a STEM career changer were used to identify ways in which the teacher’s lived experiences supported her mathematics teacher noticing and influenced her adaptive teaching practices. Student surveys and individual student focal interviews were analyzed to assess the students’ perceptions of the teacher’s support and their …

Investigating Patterns Using Analyzing Digital Images (Adi) Software, Jennifer Welborn, Wayne Kermenski Jan 2017

Investigating Patterns Using Analyzing Digital Images (Adi) Software, Jennifer Welborn, Wayne Kermenski

Patterns Around Us

The mean and variation of a population are easily seen by graphing the number of individuals that have a trait of a given value. In this experiment, we will investigate color variation found in a mealworm population using ADI.

In this investigation, we will use digital images and ADI to measure the increased surface area created by villi located in the small intestines.

Wrinkling Of A Floating Sheet, Narayanan Menon Jan 2017

Wrinkling Of A Floating Sheet, Narayanan Menon

Patterns Around Us

The objective of today’s work will be to generate wrinkle patterns on very thin polymer films using the forces generated by the surface tension of a water drop. You’ll do a few sizes of water drop and we’ll give you a couple of thicknesses of film. Digital images of the pattern will allow us to make observations of the number and size of the wrinkles generated. We will try to develop an understanding of the dependence of the pattern on the materials used and the forces applied
