One plausible method for ensuring students are truly understanding science fundamentals beyond being actively and intellectually engaged is to consider how informal learning environments can provide meaningful relevancy by connecting to real-world instances. Transforming traditional science centers into informal learning centers will ensure that…

The Next Generation Science Standards (NGSS) impact students in substantive ways. These standards move beyond textbooks to emphasize hands-on inquiry focused on real-world phenomena -- making students, rather than teachers, the primary actors in the NGSS science classroom. The six-year NGSS Early Implementers Initiative has supported a group of…

This qualitative research study explored perceptions of best teaching strategies implemented by science teachers for learning disabled high school students from one northwest Texas high school. Four research questions guided the exploration of personal and scholarly practices that high school teachers perceived worked best in their science…

STEM instruction often uses visual representations. To benefit from these, students need to understand how representations show domain-relevant concepts. Yet, this is difficult for students. Prior research shows that physical representations (objects that students manipulate by hand) and virtual representations (objects on a computer screen that…

This qualitative study was designed to introduce STEM (Science, Technology, Engineering, Mathematics) activities to preservice science teachers and identify their views about STEM materials. In this context, a competition was organized with 42 preservice science teachers (13 male- 29 female) who took Instructional Technologies and Material…

"Hop to It," a week-long herpetology-focused summer STEM camp for rising fourth-, fifth-, and sixth-grade girls, provided young females with authentic, hands-on science experiences, allowing them to develop the habits of thought and processes of action used by STEM field experts while also engaging and sustaining their interest in the…

Advances in 3D printing technology over the past decade have led to its expansion into all subfields of science, including chemistry. This technology provides useful teaching tools that facilitate communication of difficult chemical concepts to students and researchers. Presented here is the use of 3D printing technology to create tangible models…

Three-dimensional (3D) chemical models are a well-established learning tool used to enhance the understanding of chemical structures by converting two-dimensional paper or screen outputs into realistic three-dimensional objects. While commercial atom model kits are readily available, there is a surprising lack of large molecular and orbital models…

This article presents a case study of a child who attended Projeto Clicar, an extended education program designed for the social and educational development of children living on the streets of São Paulo, Brasil. We discuss how his discovery of the existence of dinosaurs unleashed a sustained artistic output at Projeto Clicar. We document the…

This study utilized a semi-structured interview approach to identify how college methods professors in Nebraska are engaging pre-service K-12 teachers with the Next Generation Science Standards and to determine if this information is being carried over to Nebraska K-12 classrooms. The study attempted to address these items by answering the…

A laboratory experiment is described that introduces second-year undergraduate organic chemistry students to organic electronic materials. The discovery of metallic conductivity in the charge transfer salt tetrathiafulvalene tetracyanoquinodimethane (TTF-TCNQ) is a landmark result in the history of organic electronics. The charge transfer…

For much of the northern United States, the months surrounding the winter solstice are a time of increased darkness, low temperatures, and frozen landscapes. Each year, the ubiquitous white ice crystals that blanket regions of the north go uninvestigated. Instead of hunkering down indoors with their classes, however, teachers can take advantage of…

Imagine a microscopic world filled with tiny motors, ratchets, switches, and pumps controlled by complex signaling and feedback systems. Now imagine that these parts can assemble themselves. This is the world presented to students in the protein structure unit of a genetic engineering course. Students learn how protein folding gives rise to the…

A variety of fruits and vegetables, including raspberries, blueberries, Concord grapes, blackberries, strawberries, peaches, eggplant, red cabbage, and red onions, contain flavonoid compounds known as anthocyanins that are responsible for the blue-red color and the astringent taste associated with such foods. In addition, anthocyanins exhibit a…

A modified total synthesis of (S)-goniothalamin is described for an advanced course in organic chemistry. This experiment gives students an opportunity to handle organometallic reagents and perform an enzymatic kinetic resolution and a metathesis reaction, all in the same synthesis. Furthermore, students learn flame-drying techniques for the…
