Socioscientific Issues: A Path Towards Advanced Scientificliteracy And Improved Conceptual Understanding Of Socially Controversial Scientific Theories, Dean William Pinzino

Graduate Theses and Dissertations

Abstract

This thesis investigates the use of socioscientific issues (SSI) in the high school science classroom as an introduction to argumentation and socioscientific reasoning, with the goal of improving students' scientific literacy (SL). Current research is reviewed that supports the likelihood of students developing a greater conceptual understanding of scientific theories as well as a deeper understanding of the nature of science (NOS), through participation in informal and formal forms of argumentation in the context of SSI. Significant gains in such understanding may improve a student's ability to recognize the rigor, legitimacy, and veracity of scientific claims and better ...

Guided-Inquiry Based Laboratory Instruction: Investigation Of Critical Thinking Skills, Problem Solving Skills, And Implementing Student Roles In Chemistry, Tanya Gupta

Graduate Theses and Dissertations

Dissertation Abstract

Recent initiatives in the laboratory curriculum have encouraged an inquiry-based approach to learning and teaching in the laboratory. It has been argued that laboratory instruction should not just be hands-on, but it should portray the essence of inquiry through the process of experiential learning and reflective engagement in collaboration with peers and in facilitation by the instructor. A student-centered active learning approach may be an effective way to enhance student understanding of concepts in the laboratory. The dissertation research work explores the impact of laboratory instruction and its relevance for college-level chemistry. Each chapter is different from the ...


Sustainable Soils, Sustainable Communities: Promoting The Environmental And Social Sustainability Of Human-Soil Interactions In Iowa, Eric Britt Moore Jan 2012

Sustainable Soils, Sustainable Communities: Promoting The Environmental And Social Sustainability Of Human-Soil Interactions In Iowa, Eric Britt Moore

Graduate Theses and Dissertations

Few environmental factors play as significant a role in shaping ecological and social communities as soil. Soil performs a number of functions that are critical to humanity. The incredible capacity of soil to support life does not make it immune to abuse. Although agriculture is often cited as the primary culprit, the degradation of soils is not limited to farmers. Urban populations also contribute to soil degradation through ignorance and tacit support of unsustainable soil management practices. If unsustainable soil management practices are to be stopped, then both rural and urban populations must take action to better understand and interact ...
