In this paper we investigate the ways that students' problem-solving behaviors evolve when solving multi-faceted, context-rich problems within a structured, computer-based learning environment. During the semester, groups of two or three students worked on several problems that required drawing on more than one concept and, hence, could not be readily solved with simple "plug-and-chug" strategies. The problems were presented to students in a data-rich, online problem-solving environment that tracked which information items were selected by students as they attempted to solve the problem. The students also completed a variety of tasks, like entering an initial qualitative analysis into an online …

Duties of engineers and technologists often entail designing and implementing solutions to problems. It is their responsibility to be cognizant of the impacts of their designs on and thus, their accountability to society in general. They must also be aware of subsequent effects upon the environment. They need to be able to concurrently satisfy these often competing priorities as well as constraints specific to the technical challenges at hand. Responding to these contending forces are the growing fields of green engineering and sustainable engineering. Both of these areas encompass many concepts, ideas and tools all of which are essential for …

This paper reports on the first stage of building an educational tool for international graduate students to improve their academic writing skills. Taking a text-categorization approach, we experimented with several models to automatically classify sentences in research article introductions into one of three rhetorical moves. The paper begins by situating the project within the larger framework of intelligent computer-assisted language learning. It then presents the details of the study with very encouraging results. The paper then concludes by commenting on how the system may be improved and how the project is intended to be pursued and evaluated.

The society in which we live has developed an insatiable demand for energy and material goods. In particular, recent data reveals that the aggressive pursuit of improved standards of living in the highly populated countries of India and China has contributed to increased demand for fossil fuels, which has exacerbated the recent spike in energy costs. Historically, these needs have been met primarily by fossil fuels and other non-renewable raw materials. As environmental concerns grow, however, renewable resources are gaining increased attention. This paper examines the emergence and importance that bio-based industries are increasingly beginning to play. A bio-based enterprise, …

The society in which we live has developed an insatiable demand for energy and material goods. Historically these needs have primarily been met by utilizing fossil fuels and other nonrenewable raw materials. As environmental concerns grow, however, renewable resources are gaining increased attention. This paper examines industrial biorefineries, which are at the leading edge of the development of emerging biobased industries. Biorefineries, similar in concept to traditional petroleum refineries, utilize various conversion technologies to produce multiple products, including fuels, chemicals, industrial products, and electrical power from renewable biomass sources, such as corn stover, residue straw, perennial grasses, legumes, and other …

Renewable Energy Alternatives—A Growing Opportunity For Engineering And Technology Education, Kurt A. Rosentrater

A hallmark of the United States’ economic growth is an ever-increasing demand for energy, which has traditionally been met primarily by combusting the hydrocarbons found in fossil fuels. As national security and environmental concerns grow, renewable energy resources are gaining increased attention. Unfortunately, there is currently a dearth of renewable energy coverage in engineering and technology curricula. The objectives of this paper are to examine historical energy data for both traditional as well as alternative energy sources, and to motivate educators to address this gap. Even with the progressive developments of non-traditional energy sources over the years, the U.S. still …

Quantum chemistry has been a staple of undergraduate curricula for several decades. For the most part, however, it has been the rare course in quantum chemistry that advances much beyond the hydrogen atom (or perhaps H2) in terms of describing the electronic structure of real molecular systems. Driven in part by staggering advances in computer technology during the last 15 years or so, which have rendered possible on a laptop calculations that once would have taxed the largest mainframes available, this situation now seems to be changing (1–3).

Computerized instruction has captured the interest of many educators as a means of individualizing language study for their students. The quality of this individualization is maximally dependent on the degree to which a computer can understand what the student communicates to it usually by typing a message on the keyboard. This article provides an overview of this student communication, or input: its types, its recognition, and some uses of its recognition. A general understanding of the potential of student-computer interaction will enlighten those who are examining Computer Assisted Language Learning (CALL) lessons for use in their curriculum. Some of this …
