Using Podcasts To Bring National Estuarine Research Reserves Into The Classroom For Grades 6-12, Kaitlyn M. Dirr

Senior Theses

In a typical classroom setting, there are significant challenges to exposing students to concepts related to earth sciences and the environment. These challenges are exacerbated when conveying lessons about geographic areas with limited access, such as oceans and coastlines (Louv, 2010). It is now more important than ever for environmental education to improve and adapt to our changing world. Educators may have the opportunity to bring these subjects to life by using media content such as podcasts to introduce students to new places and the scientists, managers and educators that work in those spaces. In the United States, there exists …

Middle Savannah River: An A/R/Tographic Ecopedagogical Ethnography Experimenting With Rhizomatic Perspectives, Lisa Augustine-Chizmar

Electronic Theses and Dissertations

This research is an experiment in perspective. Using the four commonplaces (Schwab, 1978), I practiced letting the Savannah River teach me what there is to know about the water, the land, the people, and the other entities that depend on ki through artistic, ethnographic, and ecopedagogical lenses. The ethnographic findings describe the social actors that depend on ki and give a voice to the River. The a/r/tographic findings display the River on a canvas map through two hundred years using paint, clay, photography, video, abstract acrylics, and fabric. Together, these methods contribute to a unique ecopedagogical journey. This word cloud …

Investigating Students' Interpretations Of Ecological Food Webs, Christopher Neil Grissett

USF Tampa Graduate Theses and Dissertations

To better prepare undergraduate students for current and future biological challenges, scientists, educators and researchers in the Vision and Change report recommended five core conceptual areas essential for the improvement of biological literacy, one of which is biological systems. Systems are an identified core concept that may help promote biological literacy. One example of a system that students have difficulty understanding is an ecological food web, which consists of parts or components interacting with one another to perform a given phenomenon. The intricacies of this system tend to confuse students and can produce naïve conceptions that could hinder future learning …

Deciphering Climate-Driven Changes In Planktonic Diatom Communities In Lake Superior, Amy Kireta

Electronic Theses and Dissertations

Climate change is affecting lake systems throughout the world, including Lake Superior, the world’s largest lake by surface area. Climate-driven physical changes in Lake Superior are well documented, but there is still substantial uncertainty of how recent biological changes are related to climate change. This research addresses these uncertainties using a variety of approaches to understand the effects of modern climate-driven changes on Lake Superior diatom communities. First, I developed models for environmental variables related to diatom abundance using 10 years of summer monitoring data. Second, I investigated changes in fossilized diatom relative abundances before, during, and after the Medieval …

Learning To See The Forest For The Corn: Establishing Sense Of Place And Community In A Field-Based Ecology Course For Pre-Service Educators, Michelle Edgcomb Friday

Theses and Dissertations

In this dissertation grounded theory techniques were used to characterize pre-service educators’ experiences in a semester-long, field-based ecology course. Through participation in a citizen science project, participants formed a community of practice that extended their conceptions of themselves as ecology students and scientists. Extended field experiences in a variety of local ecosystems contributed to the development of a sense of place. Paired fieldwork with lecture aided their developing ecological literacy and their understanding of place-based pedagogy. All of these combined to support their growing understanding of their role in field-based ecology education. Lack of background in ecology and ecology pedagogy …

Minority Middle And High School Students' Interest In Science: An Exploration Of Teachers' Perceptions, Caroline Makere

Dissertations

A high school teacher conducted a study about minority middle and high school students’ interest in science. The problem was to find out why African American and Hispanic students were showing very little interest in science. The researcher used four middle school science teachers and nine high school science teachers, all from inner city schools in a big city of the Midwest United States except for one middle school teacher from a nearby suburb. The participants answered a survey questionnaire followed with a face-to-face recorded interview. The findings of the study confirmed that students showed little interest in science due …

Why Are Students Doing Research? Examining The Motivation Of Students Involved In Undergraduate Research Programs, Andrew Layne Mcdevitt

Theses and Dissertations

Use of self-determination theory (SDT) within the science classroom focuses primarily on ways to integrate intrinsic motivation into students' identity. Experiential learning plays a large role in promoting learning by shaping students' interests, identity, and intrinsic aspirations. This phenomenological research study sought to understand how experiential learning experiences helped influence career aspirations of graduate students within ecological disciplines. By determining how their experiences met three basic psychological needs outlined by SDT (competence, autonomy, and relatedness), we were able to examine which regulators drove motivation.

In the qualitative pilot study, participants developed a genuine enjoyment and appreciation for their discipline as …

Assessing The Impact Of Historical Story Telling On Student Learning Of Natural Selection, Janice Marie Fulford

Dissertations

Research suggests that because of its historical nature, the learning of evolutionary biology is problematic compared to that of other science disciplines. While explanations used in historical sciences often employ historical narratives, which are distinct from narratives in other contexts, such as stories, the two types of narratives have structural similarities that suggest the potential role of stories based in the history of science for the teaching of evolutionary biology. Stephen Klassen, a prominent science educator, has studied how stories from the history of physics can promote the learning of and attitudes towards science. Klassen’s pioneering work identifies structural components …

School Gardens: Cultivating A Child’S Nutritional Habits, Environmental Knowledge, And Sustainability Practices, Jeffrey Meltzer

Honors Theses

School gardens have existed since the late nineteenth century and today are becoming increasingly popular in many parts of the world, including where I studied in Maine and Australia (AUS). Multiple organizations support school gardens in Maine, including the Maine School Garden Network, which has over 125 registered school gardens. In AUS, the Stephanie Alexander Kitchen Garden Foundation primarily supports the school garden movement and has over 800 registered school gardens. While many researchers have studied school gardens, few have compared two countries, focused on environmental sustainability, or investigated Maine in particular. This thesis combines information from literature reviews, and …

Parentage Analysis And Conservation Genetics Educational Material For The Eastern Hellbender Salamander, Cryptobranchus Alleganiensis Alleganiensis, Sarah A. Chudyk

Master's Projects

Populations of the Eastern hellbender salamander, Cryptobranchus alleganiensis alleganiensis, are declining, making this a species of special concern in New York State and under consideration for Federal Endangered Species listing. As a result of this decline, the New York State Department of Environmental Conservation and the Buffalo Zoo initiated a headstarting program with an egg mass found in the Allegheny River drainage. The juveniles being raised by the Zoo will be released back into the watershed and so understanding the genetic diversity and parentage of these hellbenders will inform the reintroduction efforts. Furthermore, in order to determine how to …

The Natural Provenance: Ecoliteracy In Higher Education In Mississippi, Sarah Elizabeth Wheeless

Dissertations

Researchers have suggested that there is an increasing apathy in the study of natural history both in academic settings and in the scientific community (Schmidly, 2005). Natural history is the cornerstone of ecological literacy. However, most studies of environmental knowledge do not directly address knowledge of local natural history. Instead, they concern knowledge of human environmental issues, environmental concepts, or broad ecological knowledge. Ecoliteracy established the study of natural history as fundamental to environmental knowledge and seeks to determine levels of knowledge of local environments and factors associated with that knowledge (Pilgrim et al., 2007).

This study investigated ecoliteracy in …

An Account Of Novice Phylogenetic Tree Construction From The Problem-Solving Research Tradition, Terrance E. Brisbin

Dissertations

Both the content and strategic knowledge used in phylogenetic tree construction are described to account for novice performance. A review of the literature is used to place this research with respect to studies in: problem solving studies (both expert, and novice), the history and practice of evolutionary systematics, and the teaching of evolution. The computer-based problem-solving environment is discussed along with model problems used for the research.

Each of the five research problems consists of an encoded matrix containing phylogenetic data organized by taxa and characters. Twelve participants (high school students) volunteered to solve the research problems, on their own …

A Limnological Investigation Of A Tropical Fresh-Water Ecosystem: The Belize River, Belize, Central America, Victor J. Gonzalez

Dissertations

The limnology of the Belize River, from the region of Spanish Lookout to the region of Belize City, was investigated from 1977 through 1979. The investigation was done primarily during the months of May through August, covering the two seasonal changes--wet and dry--that occur in this tropical region. The investigation sought to describe various parameters of the Belize River so as to gain an understanding of this tropical fresh-water ecosystem and to provide basic information needed for the development of management programs.

Water samples were collected from eight stations and analyzed for acidity, alkalinity, carbon dioxide, chloride, sodium chromate, hexavalent …

A Comparative Investigation Of Understanding Of Ecological Content Between Eighth And Tenth Grade Pupils, David Lee Herbenson

All Master's Theses

The study had two major purposes. One purpose was to determine if Covington Junior High School eighth grade pupils understood the basic ecological ideas and facts presented to them in a teacher-designed one semester course entitled Environmental Concepts Orientation (ECO). The second purpose was to find out the degree of competence attained by the eighth grade pupils as compared to tenth grade pupils taking a one year ecologically oriented course in the nationally developed Green Version BSCS biology series at Camas, Washington.

Introducing Aquatic Ecology To Ninth Graders, Inez P. Sutton

Masters Theses

Chapter I

Introduction

In discussing the basis for teaching high school biology, Van Deventer¹ states, "...the present typical course in high school biology serves adequately neither the terminal student nor the college entrance student." He holds that today's courses present watered-down versions of college courses to the student before the intelligence of the student has matured enough to grasp such subject matter. As a result there is very little carry-over value from such courses, and the students may even develop a dislike for biology. This study constitutes an effort to understand these problems and to devise ways of solving …
