Integrating a Space for Teacher Interaction into an Educative Curriculum: Design Principles and Teachers' Use of the iPlan Tool

Implementation of reform curricula requires teachers to adopt new approaches to teaching. Research has provided promising results about the influence of educative curriculum on teachers’ learning and instruction. However, this approach generally focuses on teachers as isolated learners. Using a design-based research approach, the authors developed a web-based tool, iPlan, which provides access to educative curriculum materials in an online interactive learning platform.

Exploring Students’ Experimentation Strategies in Engineering Design Using an Educational CAD Tool

Experimentation is one of the important strategies used in engineering design to understand the relationship between relevant variables so that they can be manipulated to generate optimized solution for a particular problem or design. The understanding of students’ experimentation strategies allows educators to help students improve their design experiments by providing scaffolds or guidance. The purpose of this study is to investigate students’ experimentation strategies while they work on a design challenge.

The Role of Simulation-Enabled Design Learning Experiences on Middle School Students’ Self-generated Inherence Heuristics

In science and engineering education, the use of heuristics has been introduced as a way of understanding the world, and as a way to approach problem-solving and design. However, important consequences for the use of heuristics are that they do not always guarantee a correct solution. Learning by Design has been identified as a pedagogical strategy that can guide individuals to properly connect science learning via design challenges.

Automated text scoring and real‐time adjustable feedback: Supporting revision of scientific arguments involving uncertainty

This paper describes HASbot, an automated text scoring and real‐time feedback system designed to support student revision of scientific arguments. Students submit open‐ended text responses to explain how their data support claims and how the limitations of their data affect the uncertainty of their explanations. HASbot automatically scores these text responses and returns the scores with feedback to students. Data were collected from 343 middle‐ and high‐school students taught by nine teachers across seven states in the United States.

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.

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.

Advancing Online and Blended Professional Development Through NSF's DRK-12 Program

The STEM education landscape continuously shifts in response to factors such as changing workforce demands; new knowledge about how children and adults learn; better strategies for broadening participation in under-served and underrepresented populations; and changes in local, state, and national policy. Empowering teachers with new knowledge and approaches to navigate this changing landscape requires ongoing, high-quality opportunities for professional growth.
