InterMath is a professional development effort designed to support teachers in becoming better mathematics educators. It focuses on building teachers' mathematical content knowledge through mathematical investigations that are supported by technology. InterMath includes a workshop component and materials to support instructors. For each of the following problems, consider how you would pose the same problem to your students. Would the wording need to change? Would you need to include more pictur
Dual-phase steel water quenched from 800°C
The steel sample with composition same as above was quenched from 800°C. The microstructure shows higher volume fraction of martensite. The martensite is appearing as the same straw-coloured entities. The straw tint is not influenced either by martensite size or its C-content. The retained austenite is appearing as bright white fine particles associated mostly with martensite.
A topology construction from line drawings using a uniform plane subdivision technique
The paper describes an algorithm for constructing the topology from a set of line segments or polylines. The problem appears for example at land-maps that have been drawnby general-purpose drawing packages or captured from blue-prints by digitalisation. The solution comprises two steps; in the first step inconsistencies in the input data aredetected and removed, and in the second step the topology is constructed. The algorithm for topology construction consists of two phases: determination of a

This collection including photographs, documents, newspaper clippings, political cartoons, works of art, oral histories, and other primary sources draws from Calispheres total content, and also features more than 20,000 specially digitized primary sources from special contributors.
Investigating the evolution of grain scale microstructure during large plastic deformation of polycr
Polycrystalline deformation and its modeling by currently used crystal plasticity models has been investigated by means of experiments involving direct measurement of deformation induced orientation changes. The experiments used a polycrystalline aluminum sample with columnar grains, whose initial lattice orientations were mapped using the Orientation Imaging Microscopy (OIM) technique. The sample was then deformed under (i) simple compression by 40% along the axis of the columnar grains and (ii
Learning and using requirements representation notations by information technology professionals
This dissertation describes a unified system modeling approach and notation that accommodates the user view and a pilot study of the ability of information technology (IT) professionals to learn and use requirements notations to represent user interface requirements. The study mapped a non-user view requirements notation into a user-view requirements notation. In so doing, it showed that the issues and concerns of non-technical users could be integrated into the overall requirements for a system
Computer enhanced education in undergraduate dietetics programs
Since computer technology was reported as underutilized on a previoussurvey, the objective of this study was to strengthen the role of technology forundergraduate programs in food and nutrition. The purpose was to determinewhether attendance at a workshop on computer applications would increase thevariety and frequency of use of computer applications and educational materials inundergraduate nutrition programs and would stimulate the development of computerenhanced education materials. A 89-item

Novel heterostructure metal-semiconductor-metal (HMSM) photodetectors with resonant cavity for fiber
Monolithically integrated photoreceivers, optoelectronic integrated circuit photoreceivers (OEIC), are important components for fiber optic communications. Two novel delta modulation doped HMSM photodetectors with resonant cavities have been designed with improved performance in terms of responsivity, speed, sensitivity, and wavelength selectivity to fulfill the increasingly more stringent requirements of transmission systems. The major contributions of the author during the Ph.D. period are as

Digital Storytelling in the Classroom and Beyond
This workshop explores how contemporary technology tools empower students and teachers to engage in highly creative and reflective tasks to organize and present information, and express emotions, ideas and knowledge through multimedia creations known as digital stories. Digital storytelling is increasingly becoming popular in schools all over the world as an engaging technology-based learning strategy. In this workshop, the participants will be exposed to powerful user-friendly and cost-free tec
To Know Ourselves
This site tells about the Human Genome Project and provides general information about and links to the coordinated effort to determine the complete sequence of the DNA in the human genome. It surveys the project's goals, the tools being used to map genetic code, the spin-off technologies generated by the project, and the ethical, legal, and social implications of knowing our genetic blueprint.
EIA's Kids Page
The U.S. Department of Energy, Energy Information Administration (EIA) hosts a student-friendly website with a variety of information and activities about energy. NEED assists EIA with web content. The Energy Kid's Page consists of several main categories: Energy Facts, Fun and Games, Energy History, Classroom Activities, Related Links, and a Glossary.

The Law of the Internet
The Internet is at once a constructive and disruptive technology. As more and more of our lives move online, we are faced with opportunities to do new and amazing things. Concurrently, we encounter problems that no one anticipated as we collectively built the internet as we know it today. This seminar will consider some of the most intriguing of the issues to which the advent of the internet has given and continues to give rise. It will focus on a cluster of topics about which any computer user
