The desire to observe and understand the natural world is strong in young children, but high school students often consider science irrelevant to their daily lives. Therefore, as teachers of older age groups, the authors constantly struggle to engage students in scientific exploration so they can master concepts and appreciate the nature of…

In this article, the author discusses the CHANCE (Connecting Humans and Nature in the Costa Rican Environment) program, a coordinated effort between The Pennsylvania State University (PSU) and the Pennsylvania Department of Education that trains 9th- through 12th-grade teachers to be more like scientists and develop a unique, pedagogical tool for…

The founder of Penn State's Laboratory for Public Scholarship and Democracy and chair of Penn State's Public Scholarship Associates establishes public scholarship's connections with democracy by distinguishing public scholarship from service, outlining a curriculum of consequence, and suggesting the constitutional roots of public scholarship.

This paper describes an easy experiment to study the absorption and action spectrum of photosynthesis, as well as the inhibition by heat, high light intensity and the presence of the herbicide 3-(3,4-dichlorophenyl)-1,1-dimethylurea (DCMU) on the photosynthetic process. The method involves measuring the chlorophyll fluorescence emitted by intact…

We describe a polymerase chain reaction (PCR) protocol suitable for use in secondary schools and colleges. This PCR protocol can be used to investigate genetic variation between plants. The protocol makes use of primers which are complementary to sequences of nucleotides that are highly conserved across different plant genera. The regions of…

Stress facilitates memory formation, but only when the stressor is closely linked to the learning context. These effects are, at least in part, mediated by corticosteroid hormones. Here we demonstrate that corticosterone rapidly facilitates synaptic potentiation in the mouse hippocampal CA1 area when high levels of the hormone and high-frequency…

Understanding the function of the distinct amygdaloid nuclei in learning comprises a major challenge. In the two studies described herein, we used c-Fos immunolabeling to compare the engagement of various nuclei of the amygdala in appetitive and aversive instrumental training procedures. In the first experiment, rats that had already acquired a…

The purpose of this brief paper is to provide insight into the kinds of work being done by an education research group in a US physics department. As will be evident, instructional technology raises many interesting questions and lends itself to a wide variety of studies. References and contacts are provided for readers wanting more detailed…

A laboratory experiment is presented for the upper-level undergraduate physical chemistry curriculum in which the ternary phase diagram of water, 1-propanol and n-heptane is measured using proton nuclear magnetic resonance (NMR) spectroscopy. The experiment builds upon basic concepts of NMR spectral analysis, typically taught in the undergraduate…

The kinetics experiments on the ligand-C[subscript 60] exchange reactions on (dihapto-[60]fullerene) pentacarbonyl tungsten(0), ([eta][superscript 2]-C[subscript 60])W(CO)[subscript 5], form an educational activity for the inorganic chemistry laboratory that promotes graphical thinking as well as the understanding of kinetics, mechanisms, and the…

In this article, the authors address the gap between the spirit of the national history standards and what now is occurring in middle grades classrooms constrained by state standards and the No Child Left Behind policy. The authors suggest that creating a lab-like classroom environment to promote historical inquiry offers one means to close that…

This paper provides an overview of U.S. Department of Education programs authorized and funded under federal law. It includes information as well on the laboratories, centers, and other facilities funded by the Department that provide important resources for education. Each entry, which gives a brief overview of a program or resource, is listed…

A group of faculty at the University of Georgia obtained funding for a research and development facility called the Learning and Performance Support Laboratory (LPSL). One of the LPSL's primary needs was obtaining a portable usability lab for software testing, so the facility obtained the "Luggage Lab 2000." The lab is transportable to…

At the Homestead Campus of Miami-Dade Community College (MDCC), in Florida, one barrier to fully integrating technology in the classroom was identified as the low-level of student computer skills. To address the problem, the campus undertook a project to establish a technology basic skills workshop for all students. In informal interviews to…

The Center for Applied Social Issues (CASI), at Ohio's Sinclair Community College, is an interactive environment for sociology students, providing hands-on, course-integrated opportunities for learning sociological principles. Opened in fall 1992, CASI consists of computer applications, audio-visual aids, and table-top activities that extend…
