and as knowledge has grown from research in complex systems andgeneral systems theory, it has become clear that non-linearity, discontinuous behavior, anduncertainty are the rule rather than the exception in all complex systems including earthsystems.1 The trunk of the tree of knowledge must now be ethics, especially when designingsystems that interact with natural systems. In engineering, this fundamental conceptual changecan be represented as a macro-ethic.This paper lays the foundation for a fundamental macro-ethic that can guide engineering decisionmaking in the future. The conceptual framework for the macro-ethic is based on the work of twoenvironmental philosophers Aldo Leopold and J. Baird Callicott. Leopold created the concept of“the

Furthermore, instructors can easily provide a wide variety of experiences for students with aminimal amount of incremental course refinements.1 Introduction One of the many challenges facing engineering educators today is the need to keep pace withtechnological advancements. Many factors must be considered before integrating new technologyinto a curriculum. Traditionally, if the technology varies widely from technology in current courseofferings, a new course is considered. Otherwise, an existing course is modified or updated. Ineither case, the process of integrating the new technology into a curriculum can be both expensiveand time consuming. Product Line and Product Family

Two yearslater we purchased the cutaway version since our use was for classroom and laboratoryapplications. The first applications of the engine were done with no deviations from theTurbine Technologies suggested practice. We found the engine to be an excellent devicefor demonstration and a definite morale builder. In the fall of 2000 we were makingbiodiesel from unused cooking oil for testing in piston diesel engines and decided to trythat fuel in our SR-30. Based on that success, in 2001 we prepared SR-30 fuel from usedcooking oil. A variety of fuels are

complete the labs on generator control, students need to know about pulse width modulation (PWM) circuits and feedback systems. While DC generators may not be the most likely machine a practicing engineer will encounter, it is felt that they provide students with a simpler introduction to machines and controllers as compared to AC or DC motors. The topic of DC generator voltage control leads naturally to DC motor speed control, AC generator voltage control and finally AC motor speed control. Recent student surveys indicate that they are satisfied with the course and that they have a grasp of the material.1 IntroductionThe typical electrical engineering course in electric rotating machinery and energy

The 30-question, multiple-choice MCI test was developed from a literaturesurvey of assessment research in science and engineering in conjunction with extensive studentinteractions. A key aspect of the MCI is discovering the student misconceptions that can be usedas the incorrect answers for each question. Hestenes et.al.1 refers to these appealing, butincorrect, choices as “distracters”, a term which has been adapted in the literature. The subjectof this paper is the description, approach, methodology, and techniques used to develop the MCIand also a discussion of early results on the nature of the broadly held student misconceptionsrevealed

In thegas absorption design experiment, the instructor imposes this variability by adjusting thepH, temperature, composition, or viscosity of the available absorbing liquid.
