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…

Through partnerships with scientists, students can now conduct research in science laboratories from a distance through remote access technologies. The purpose of this study was to explore factors that contribute to a remote learning environment by documenting high school students' perceptions of science motivation, science identity, and virtual…

As science grows in complexity, science teachers face an increasing challenge of helping students interpret models that represent complex science systems. Little is known about how teachers select and use models when planning lessons. This mixed methods study investigated the pedagogical approaches and visual models used by elementary in-service…

There is a wide range of new products emerging from nanotechnology, and "nano ice cream" is an easy one that you can use to teach topics from surface area to volume applications. In this activity, students learn how ice cream can be made smoother and creamier tasting through nanoscience. By using liquid nitrogen to cool the cream mixture, students…

Developing scientifically literate students who understand the socially contextualized nature of science and technology is a national focus of science education reform. Science educators' perceptions of risks and benefits of new technologies (such as biotechnology) may shape their instructional approaches. This study examined the perceived risk of…

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…

Traditional science instruction is typically reliant on visual modes of learning, such as textbooks and graphs. Furthermore, since science instruction is often heavily dependent upon visual cues, students with visual impairment often do not have access to the same educational opportunities in most science classes (Jones, Minogue, Oppewal, Cook,…

Describes bioluminescence and the chemistry of how it occurs. Presents information for conducting the following classroom activities: (1) firefly mimic; (2) modeling deep-sea fish; (3) sea fireflies; and (4) the chemistry of light. (PR)

Presents a series of investigations focusing on the biodegradable packing materials ("peanuts"), which provide a method for exploring science through experimentation. These activities can help fourth through sixth graders sharpen their critical thinking and science process skills. (PR)

Presented are seven investigations that examine circadian rhythms. Topics include attention span, body temperature, rhythms found in rodents and spiders, and possible genetic determination of circadian rhythms. Background information on plants and animals is given. (KR)

Reviews the literature concerning sociocultural factors, teacher influences and experiences that effect girls attitudes about entering science careers. Discusses a model of these influences on girls. Makes recommendations including increased opportunities and encouragement to foster more favorable attitudes toward science and increase science…

This study compared students' investigations with an atomic force microscope and viruses in real-time synchronous and asynchronous learning environments. Student interactions with scientists (live videoconference versus email) were examined to see whether communication patterns were different for the different modes of instruction. Students'…

Investigated were the seating patterns of target students in science classrooms to see whether there was an action zone or T zone present. Questioning level, understanding level of students, and pacing of instruction by teachers are discussed in terms of target students. (KR)

This exploratory case study investigates relationships between use of an inquiry-based instructional style and student scores on standardized multiple-choice tests. The study takes the form of a case study of physical science classes taught by one of the authors over a span of four school years. The first 2 years were taught using traditional…

This study investigated the seating patterns of target students in science classrooms to see if there was an action zone or t-zone present. Fifty-six physical science and chemistry classes were observed using the Brophy-Good Teacher-Child Dyadic Observation System. Target students were identified and their interactions were compared to non-target…
