“…The impact of electricity on the farm GHG budget will be discussed in more detail below. Like the tractor, its role in modern agriculture grew enormously in the 20 th century, from 3% or less in the 1920s to 99% of farms by the 1970s (Gustafson, 1980;McFate, 1989). Today there is a resurgence of interest in electrical energy from wind, solar and biogas, but many farmers in the 1930s and 1940s also relied on wind generators for electrical power (Gustafson, 1980;NRCan, 2005).…”

However then, as now, such on-farm power generation had a tough time competing with the cheap, centrally generated electricity (Gustafson, 1980).…”

However then, as now, such on-farm power generation had a tough time competing with the cheap, centrally generated electricity (Gustafson, 1980). One consequence of cheap electrical power is that there appears to have been little interest in improving on-farm efficiency of electrical energy use (Dyer and Desjardins, 2006b).…”

“…According to Gustafson and Morgan (2004), PLCs "have replaced hard-wired relay-based control systems in most industries because of their compact size, ruggedness, and, most importantly, their ability to be reprogrammed" (p. 277). Reprogramming a PLC allows changes to be made in the functional operation of a machine system without major physical changes in the control or output system components or wiring (Cox, 2001).…”

Programmable logic controllers (PLCs) are widely used in agricultural production and processing. Thus, agricultural systems management students should receive hands-on experience with these devices as part of their undergraduate education. However, in many cases, the cost of providing class-quantity PLCs for student laboratory use is prohibitive. This article describes a low-cost PLC trainer developed for use in a university level agricultural electricity course. A sample laboratory activity used with the PLC trainer is also described. End-of-course student comments indicated that use of the trainer had stimulated student interest in learning more about programmable logic controllers. Statement of Primary Audience:This article is primarily intended for college and university faculty teaching courses in agricultural electricity or control systems. Dickinson, A. and D.M. Johnson (2006) A low-cost programmable logic control (PLC) trainer for use in a university agricultural electricity course.

“…2 Gustafson, McCaul, and Soboyejo conducted a survey of 280 alumni during the academic year 2000-2001. Asked how their undergraduate experiences could have better prepared them for their professional careers, their top four responses included 5 : ≠ Changes in the content of engineering courses, including the use of current technology and software, more industry interactions, and real-world context; ≠ More involvement in professional organizations; ≠ An increased use of trade/professional publications within the curriculum; and ≠ Increased focus on professional skills, including ethics, teamwork, and communication.…”

Engineering accreditation criteria, as well as the Engineer of 2020 report, list lifelong learning as a critical attribute of future engineers. While exercises can be embedded in engineering curricula that promote independent learning, assessing the level at which lifelong learning has been achieved is difficult. The first year engineering curriculum at Louisiana Tech University provides activities that support development of lifelong learning skills. Examples include the requirement of student attendance at professional society meetings or service functions and independent research into global and societal issues that are likely to influence their careers. Our project-based curriculum requires skills beyond those imparted in the classroom. For example, students must learn with little or no classroom instruction to create parts and assemblies with a 3D modeling tool, to diagnose technical problems with their projects, and to learn to implement sensors as part of their design projects. By analyzing student questionnaires and curricular content, we measure the numbers of activities that promote lifelong learning as well as the extent to which these activities are completed independently. This paper will provide an overview of our first year engineering experience as well as the assessment results that help us measure the extent of lifelong learning.
