The Use Of An Industrial By-Product As A Soil Amendment And Its Effects On Soil Physical/Chemical Characteristics And Nutrient Retention, Dawn R. Hawkins

Culminating Projects in Environmental and Technological Studies

Soil physical/chemical characteristics are important in regards to the productivity of the soil. These characteristics can determine the rate at which water drains through soil, how much water is available to plants for uptake, and the speed at which organic matter breaks down within the soil. These attributes also play an important role in cation exchange capacity, pH buffering capacity, and nutrient availability; all important factors in plant/crop growth and protecting environmental quality. The purpose of this experiment is to determine the effects of mixing an industrial by-product on soil physical/chemical characteristics and soil nutrient retention, and to determine the …

A Delphi Study To Evaluate The Ability Of Technology Education To Promote Technological Literacy, Kurt R. Helgeson

Culminating Projects in Environmental and Technological Studies

This study was to develop a technology education course curriculum that would promote technological literacy. The curriculum, based on the Minnesota Plan for Industrial Technology Education (1984), was evaluated through the use of a Delphi study.

A review of the literature was conducted to identify the changing needs of society, new educational needs of society and identification of concepts of technological literacy. In addition, disciplines addressing technological literacy, methods of curriculum evaluation and expert with regard to technology education were identified through the literature review.

The curriculum evaluation was accomplished through a two round Delphi Study involving a panel of …
