Soil is a complex habitat for diverse biota. A significant challenge in teaching soil ecology is our inability to observe organisms as they live and interact in the soil. The objective of this article is to describe an interactive class project to help students visualize the sizes of different groups of soil organisms and to relate these to soil…

One goal of most courses is to prepare students with basic knowledge and skills associated with the course content. Mastery learning can be a rewarding way to encourage greater student achievement by allowing students multiple attempts to demonstrate an understanding of course concepts. This may involve repeated submissions of individual…

An optional 1-credit recitation course was developed to supplement a traditionally taught 4-credit lecture-plus-laboratory course in soil science at Oregon State University. Popular, competitive games that would be familiar to students were revised to be "soils-based" and were employed in the recitation class. These games were seen as a potential…

Concerns about faculty workload in the online environment are a reported deterrent to participation in distance teaching. To date, such concerns have been based primarily on anecdotal evidence rather than empirical research. This paper presents results of a study directly comparing the instructional workload in a turfgrass management course taught…

The World Wide Web and other computer-based media are new teaching resources for plant identification. The purpose of the experiments reported here was to test whether learning plant identification for woody and herbaceous plant material over the web was as effective, more effective, or preferred by undergraduate students when compared with…

Consumer acceptance or rejection of biotechnology is often shaped by information prepared by communicators with varying levels of scientific knowledge, awareness, and acceptance. This study compared the prior, post-workshop, and sustained (1 year) biotechnology awareness, acceptance, and attitudes of professionals who communicate biotechnology to…

It is becoming increasingly difficult to keep graduate students in forage and range science connected to producers and grazingland resources in the USA. Students must take an integrated systems approach to understanding the complexity of our grazinglands and their role in addressing critical issues. This can best be conveyed to the student by…

Evaporative cooling systems are commonly used in controlled environment plant and animal production. These cooling systems operate based on well defined psychrometric principles. However, students often experience considerable difficulty in learning these principles when they are taught in an abstract, verbal manner. This article describes an…

Forestry and agricultural education programs need to increase their public communication and cross-disciplinary activities. In this article we present a technique, Cross-Disciplinary Peer Education (CDPE), which allowed forestry students to teach student peers from other disciplines about basic forestry principles. Cross-Disciplinary Peer…

In the fall of 1993, the administrators of the Natural Resources and Environmental Science (NRES) Program at Purdue University mailed a survey to available alumni of the program for whom an address was available (386 surveys). In 2003, a similar survey was mailed to available alumni from 1994 to 2003 (283 surveys). The purpose of the 2003 survey…

Cropping systems management requires integration of multiple forms of knowledge, practice, and learning by farmers, extension educators, and researchers. We evaluated the outcomes of participation in collaborative learning groups organized to address cropping systems and, specifically, challenges of integrated weed management. Groups were…

Water quality is a critical environmental, social, and political issue in Delaware. In the late 1990s, a series of events related to water quality issues led to the passage of a state nutrient management law. This new law required nutrient management planning and established a state certification program for nutrient users in the agricultural and…

Reflecting on past experiences is an important problem-solving technique when teachers face new situations. In fact, teachers' attitudes and practices are highly influenced by their prior experiences as both learners and teachers. This paper is based on the premise that growth as an effective teacher is enhanced when one reflects more deeply about…

Soil science education is lacking in terms of accommodations for persons with disabilities. Individuals with disabilities are often excluded from soil science activities in school, and from soil science careers. GLOBE (Global Learning Observations to Benefit the Environment) is a worldwide, hands-on primary and secondary school-based education and…

Environmental Sciences Technology T272 is a course with a laboratory addressing problems in soil and water quality and organic wastes utilization to serve students from associate degree programs in laboratory science and environmental resources management at a 2-year technical college. Goals are to build basic lab skills and understand the role…
