Short Description: 
This brief offers insights from National Science Foundation-supported research for education leaders and policymakers who are broadening participation in science, technology, engineering, and/or mathematics (STEM). Many of these insights confirm knowledge that has been reported in research literature; however, some offer a different perspective on familiar challenges.

Linear Algebra and Geometry

Linear Algebra and Geometry is organized around carefully sequenced problems that help students build both the tools and the habits that provide a solid basis for further study in mathematics. Requiring only high school algebra, it uses elementary geometry to build the beautiful edifice of results and methods that make linear algebra such an important field.

Short Description: 
Linear Algebra and Geometry is aimed at preservice and practicing high school mathematics teachers and advanced high school students looking for an addition to or replacement for calculus. The materials are organized around carefully sequenced problems that help students build both the tools and the habits that provide a solid basis for further study in mathematics. Requiring only high school algebra, it uses elementary geometry to build the beautiful edifice of results and methods that make linear algebra such an important field.

#BlackGirlMagic: The identity conceptualizationof Black women in undergraduate STEM education

Much of the research in science education that explores the influence of a racial and gendered identity on science, technology, engineering, and mathematics (STEM) engagement for Black women situate their identities primarily as responses to the oppression and struggles they face in STEM. In this study, we use Phenomenological Variant Ecological Systems Theory as a strengths‐based approach to investigate 10 undergraduate Black women’s perceptions of race and gender on their STEM identity development and engagement.

Research and Product Dissemination and Sustainability: Approaches and Considerations

Many, if not most, DRK–12 projects grapple with challenges and opportunities related to dissemination and sustainability. Dissemination strategies to optimize the visibility of a project and reach of key research outputs may be part of a larger sustainability plan to support uptake of research products, models, and interventions and extend the impact of the project results.

Short Description: 
This document features issues and approaches that were discussed by a “critical friends group” in the process of providing input to a DRK-12 project on dissemination strategies. While not comprehensive, the considerations listed may serve as a reminder of what to think through when you are conceptualizing and designing your next research and development project.

From Pilots to Products: Notes from a Gathering of Researchers and Developers at the 2018 DRK-12 PI Meeting

This document captures the ideas and experiences shared by DRK–12 awardees who attended a forum to explore different routes toward product sustainability. It includes notes on types of DRK-12 products, use and adoption of products, resources needed to support dissemination and sustainability of products, sources of support, and indicators of successful product dissemination and sustainability.

Probing the Relevance of Chemical Identity Thinking in Biochemical Contexts

The solving of problems in biochemistry often uses concepts from multiple disciplines such as chemistry and biology. Chemical identity (CI) is a foundational concept in the field of chemistry, and the knowledge, thinking, and practices associated with CI are used to answer the following questions: “What is this substance?” and “How is it different from other substances?” In this study, we examined the relevance of CI in biochemical contexts and first explored the ways in which practicing biochemists consider CI relevant in their work.

Principles for Designing Large-Format Refreshable Haptic Graphics Using Touchscreen Devices: An Evaluation of Nonvisual Panning Methods

Touchscreen devices, such as smartphones and tablets, represent a modern solution for providing graphical access to people with blindness and visual impairment (BVI). However, a significant problem with these solutions is their limited screen real estate, which necessitates panning or zooming operations for accessing large-format graphical materials such as maps.

This article describes the development of four novel non-visual panning methods designed from the onset with consideration of these perceptual and cognitive constraints.

Touchscreen-Based Haptic Information Access for Assisting Blind and Visually-Impaired Users: Perceptual Parameters and Design Guidelines

Touchscreen-based smart devices, such as smartphones and tablets, offer great promise for providing blind and visually-impaired (BVI) users with a means for accessing graphics non-visually. However, they also offer novel challenges as they were primarily developed for use as a visual interface. This paper studies key usability parameters governing accurate rendering of haptically-perceivable graphical materials.

Comparing Haptic Pattern Matching on Tablets and Phones: Large Screens Are Not Necessarily Better

Significance: Touchscreen-based, multimodal graphics represent an area of increasing research in digital access for individuals with blindness or visual impairments; yet, little empirical research on the effects of screen size on graphical exploration exists. This work probes if and whenmore screen area is necessary in supporting a patternmatching task.

Short Description: 
The current study investigates two questions: (1) Do screen size and grid density impact a user's accuracy on pattern-matching tasks? (2) Do screen size and grid density impact a user's time on task?

The complex interplay between examples and proving: Where are we and where should we head?

Our work suggests re-conceptualization of research concerning students’ over reliance on example-based reasoning, moving from a view of such reasoning as a stumbling block to quickly overcome toward a view of such reasoning as a necessary and critical foundation in learning to prove. We have extended prior research and have developed a comprehensive analytic framework (CAPS: Criteria-Affordances-Purposes-Strategies) for characterizing and making sense of the roles and uses of examples in proving-related activities of secondary school students, undergraduate students, and mathematicians.
