Considers teaching as an activity in which teachers deliberate in the practical domain to decide on actions and goals. Argues that because practical reasoning is similar to scientific reasoning, a model of practical conceptual change can be developed that is analogous to the conceptual change model. Examines two case studies of teachers using the…

Examines how, through discourse processes, a third grade teacher and her students came to situationally define science in their classroom. Uses a discourse analytical approach to examine the classroom members' experimentation logic, their explanations and scientific decisions, and their accounts of events. (Contains 82 references.)

Reports on part of a larger study of how 11- and 12-year-old students construct knowledge of electricity and magnetism by drawing on aspects of their experiences during the course of a school visit to an interactive science museum and subsequent classroom activities linked to the science museum exhibits. (Contains 24 references.) (Author/YDS)

Despite the central role of risk assessment in analyzing and making decisions about many environmental issues, most people are poorly equipped to understand key concepts about risk or apply them successfully. I present three class activities in which students develop a better appreciation for the magnitude of a one in a million increased risk of…

Whole Farm Nutrient Management is an upper-level, undergraduate course offered through the Department of Animal Science (AS) and Department of Crop and Soil Sciences (CSS) at Cornell University. The course (AS/CSS 412) is designed for students interested in agricultural careers and aims to help them develop a working knowledge of agricultural…

Understanding the relationships between soil, landscape, and hydrology is important for making sustainable land management decisions. In this study, scientific visualization was explored as a means to visually represent the complex spatial and temporal variations in the hydrologic status of soils. Soil hydrology data was collected at seven…

Decision cases have been used in the United States for higher education in agriculture and natural resources, as well as in extension education. Few cases have been developed for secondary education audiences and fewer yet for both secondary and higher education applications. This case was developed for use in both secondary- and university-level…

How can various features of internet-based instruction be adapted to help students with different learning styles to grasp important science concepts? Are there ways of defining and measuring these differences that instructors without much background in educational psychology might find easier to apply than some of the better-known examples? How…

How can student outcomes assessment (SOA) be incorporated into ones courses and teaching? The purposes of this article are to explore a process enacted in the Department of Agronomy at Iowa State University using SOA to: (i) develop a clearer understanding of what students should learn in a course, (ii) determine how a course or courses fit within…

Consulting forestry is an attractive professional specialization and expanding employment opportunities have made it a popular option for forestry students. Association of Consulting Foresters members were asked to rank the importance of the traditional forestry and other courses in the standard accredited forestry curriculum, where additional…

The purpose of this study was to compare secondary agricultural educators' perceptions of the benefits and problems associated with teaching agricultural education and being involved in other part-time employment activities. The sample consisted of 107 agricultural educators nonrandomly selected from three states. Sixty-nine usable questionnaires…

The Department of Environmental Science at the University of Southern Maine implemented a problem-based, cohort-learning curriculum for undergraduate environmental science majors. The curriculum was based on a five-course sequence patterned after the outline of a scientific paper. Under faculty guidance, students select local environmental…

The implementation of problem-based learning (PBL) and other inquiry-driven educational techniques is often resisted by both faculty and students, who may not be comfortable with this learning/instructional style. We present here a hybrid approach, which combines elements of expository education with inquiry-driven laboratory exercises and…

Comprehensive professional development is rarely offered to graduate students, yet would assist students to obtain employment and prosper in their careers. Our objective was to design a course framework to provide professional development training to graduate students that is comprehensive, minimizes faculty workload, and provides enculturation…

The cumulative result of almost 100 years of mining, milling, and smelting has left areas of Jasper County, Missouri, contaminated with high levels of the trace metals Pb, Cd, and Zn. The site was listed on the National Priorities List in 1990 and is now known as the Jasper County or Oronogo-Duenweg Mining Belt Superfund Site. The U.S.…
