Extensive research shows that non-formal science education programs effectively build and sustain long-term interest and persistence in science careers. Framed by expectancy-value theory, this study examined the academic and career outcomes of students who participated in a multi-year volunteer program at a science museum. Twenty-one participants…

Combined three-dimensional, haptic-enabled, virtual reality (3D HE VR) systems allow students to actively engage and explore various science concepts by leveraging user-friendly and immersive interfaces. Successful implementation of these learning tools in science classrooms hinges upon teachers' perceptions of the technology's potential as a…

There is a growing need for science educators and communicators who can support public understanding of complex science issues. Furthermore, little is known about how to nurture career aspirations for teaching science. This study examined the influence of youth volunteer experiences on career aspirations through a lens of science identity.…

National elementary science standards have included the teaching of systems for decades, however little is known about teachers' understanding of complex systems. This study focuses on how elementary pre- and in-service teachers understand and apply "systems thinking" to the water cycle. Teachers completed the Water Cycle Diagnosis Test…

Graduate teaching assistants are often left out of the science teacher education reform agenda, but these science educators are responsible for significant amounts of undergraduate instruction especially at large research universities. Within science departments specifically, a number of courses and laboratories are taught by graduate teaching…

It can be argued that the responsibilities of biology educators to their students extend far beyond the delivery of science content. Educators are also charged with ensuring that students do not temporarily memorize the information, but actively integrate it into their daily lives. Personal integration of science content should prepare students to…

Scale is one of the thematic threads that runs through nearly all of the sciences and is considered one of the major prevailing ideas of science. This study explored novice and experienced teachers' concepts of spatial scale with a focus on linear sizes from very small (nanoscale) to very large (cosmic scale). Novice teachers included…

Nanoscale science and engineering are disciplines that examine the unique behaviors and properties of materials that emerge at the size range of 1 to 100 nanometers (a billionth of a meter). Nanobiotechnology is a sub-discipline of nanoscience that has arisen more recently. Nanobiotechnology is already impacting the fields of healthcare and…

To reduce curricular fragmentation in science education, reform recommendations include using common, unifying themes such as scaling to enhance curricular coherence. This study involved 215 participants from five groups (grades 5, 7, 9, and 12, and doctoral students), who completed written assessments and card sort tasks related to their…
