Wild & Koehler, 2017). Students with visual impairments are less ready for science classes, which frequently include image-based learning objects (Darrah, 2013; Kolitsky, 2014) than their sighted peers. Academic challenges in accessing representations of visual information often occur for students with visual impairments for three reasons. First, scientific representations often do not convey meaning or information to students with visual impairments, possibly because they have not formed mental images that link them with previously stored mental images (
In the National Science Foundation funded NanoTeach development project, high school teachers participated in a year-long professional development experience where they learned about emerging nanoscale science and technology (NS&T) content and research-based instructional strategies to support effective classroom lesson design and implementation. Program participants from four states were assigned either to the fully facilitated model or to the team study approach. Case studies were prepared for four participants from the Louisiana site, two from the fully facilitated NanoTeach model group and two from the team study NanoTeach group. Data for the case studies included in this article include qualitative and quantitative data regarding the changes in teachers' NS&T knowledge and their ability to teach the content using the effective strategies included in the professional development sessions and resource materials. The case studies provide new insights into the ways teachers' integrated NS&T in the high school curriculum.
Boulder. Her research examines how educational technology can improve student engagement and student learning, often focusing on underserved populations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
