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.

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?

Cross-Case Analysis of Engineering Education Experiences in Inclusive STEM-Focused High Schools in the United States

In an attempt to broaden participation in STEM, a new type of high school is emerging, high schools which include a focus on engineering, have few or no academic admission criteria, and actively involve students of all levels of ability, known as Inclusive STEM High Schools (ISHSs). One aspect of successful ISHSs includes the intentional and explicit integration of engineering learning opportunities into coursework. The purpose of this paper is to report results of a systematic cross-case analysis exploring the extent of engineering learning opportunities in five exemplar ISHSs.

Fostering High School Students’ Conceptual Understanding and Argumentation Performance in Science through Quality Talk Discussions

Flourishing in today's global society requires citizens that are both intelligent consumers and producers of scientific understanding. Indeed, the modern world is facing ever‐more complex problems that require innovative ways of thinking about, around, and with science. As numerous educational stakeholders have suggested, such skills and abilities are not innate and must, therefore, be taught (e.g., McNeill & Krajcik, Journal of Research in Science Teaching, 45(1), 53–78. 2008).

Short Description

The purpose of our quasi‐experimental study was to examine the effectiveness of Quality Talk Science, a professional development model and intervention, in fostering changes in teachers’ and students’ discourse practices as well as their conceptual understanding and scientific argumentation. Findings revealed treatment teachers’ and students’ discourse practices better reflected critical‐analytic thinking and argumentation at posttest relative to comparison classrooms.

Using a Three‐dimensional Thinking Graph to Support Inquiry Learning

The use of external representations has a potential to facilitate inquiry learning, especially in hypothesis generation and scientific reasoning, which are typical difficulties encountered by students. This study proposes and investigates the effects of a three‐dimensional thinking graph (3DTG) that allows learners to combine in a single image, problem information, subject knowledge (key concepts and their relationships), and the hypothesizing and reasoning process involved in exploring a problem, to support inquiry learning.

Reframing Inclusive Science Instruction to Support Teachers in Promoting Equitable Three-Dimensional Science Classrooms

In A Framework for K-12 Science Education, the National Research Council frames inclusive science instruction as a collection of strategies for teachers to engage students. In this conceptual article, we reframe inclusive science instruction by examining the literature in science and multicultural education and describe five elements to support teachers in realizing inclusive science instruction as a pedagogical shift.

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.

Improving the preparation of novice secondary science teachers for English learners: A proof of concept study

This proof of concept study investigated a secondary science teacher preparation intervention in six university programs across Arizona, California, and Texas. Researchers and science method instructors (SMIs) collaboratively restructured respective science method courses to hold fidelity to an interrelated set of instructional practices that attend to science learning as envisioned in a Framework for K–12 Science Education, while also creating contextualized spaces for language and literacy development targeted to English learners (ELs), but also supportive of “mainstream” students.
