Addressing Public Perceptions About Cell-Based Meat And Cellular Agriculture Through Metaphors, Yvette Emma Hubbard

English Theses & Dissertations

Today’s food movement places organic, holistic, and natural foods as priority. The idea aims for better human health, a farm-to-table community, and environmental sustainability. Soon a new meat alternative will become part of the ongoing food movement. What is it? Cell-based protein. It is a protein alternative to livestock protein. It is real protein from a real breathing animal. Cell-based beef for example is grown in a lab with cells from a living cow that does not have to die or be slaughtered. It is destined to become the new protein architecture on the horizon. Parts of this paper are …

Riverology: Promoting Stewardship Of Rivers Through Youth Participation In Science And Art, Robin R. Dunbar

Institute for the Humanities Theses

This project focuses on mentoring children to help reduce marine debris in their local river by implementing one of ten lessons from an inquiry-based Riverology curriculum to empower youth voice, increase geo-literacy, and spatial thinking. Eighteen participants aged seven and eight, piloted Riverology Lesson 2: What Do I Know or Imagine about the Elizabeth River? that includes six steps: inquire, visualize, draw, share, act, and reflect. The children were asked to make drawings before and after viewing an Elizabeth River Story Map presentation (Dunbar, 2021a). The drawings were then compared to see if the participants included marine debris, stewardship solutions, …

Science In The School Library Inquiry Model (Sslim): A Mixed-Methods Case Study Of The Implementation Of A Science And Information Inquiry Curriculum In An Elementary Library, Bree L. Ruzzi

Teaching & Learning Theses & Dissertations

Data indicate that students in the U.S. may start school with lower levels of science understanding and that these levels may consistently remain lower throughout their public-school career. With deficits in science achievement starting in the earliest years of students’ education, benefits may be gained by exploring alternate resources and alternative environments that can support young student’s science education and achievement. A largely unexplored area for science instruction is in the school library. This dissertation, a mixed-methods, case study, examined the creation and implementation of a novel information and science inquiry model and curriculum, SSLIM. This curriculum was created and …

Investigating Application Of The Self-Explanation Learning Strategy During An Instructional Simulation, Paul Michael Macloughlin

STEMPS Theses & Dissertations

Computer-based simulations effectively support the acquisition of scientific knowledge when combined with a guided learning approach. Active learning drives complex cognitive processes that enable the integration of new information with existing knowledge. The iCAP (Interactive, Constructive, Active, Passive) Framework provides a conceptual model to describe different types of active learning. Computer-based simulations fit neatly within this framework. Similarly, self-explanation is a generative learning strategy that fits within this framework. Promoting self-explanation using instructional prompts is an effective method for driving application of the strategy. This study compared three combinations of self-explanation prompt and learner activity (closed prompts – overt activity, …

Student Global Mobility: An Analysis Of International Stem Student Brain Drain, Margaret E. Gesing

Educational Foundations & Leadership Theses & Dissertations

This study seeks to understand global mobility patterns of international graduate STEM students studying in the United States. Using data from the NSF Graduate Students in Science Survey (GSSS), this study investigates the political, economic, and social factors affecting students' intent to stay or go, identifying differences based on students' country of origin within World Bank defined categories of gross national income (GNI) per capita. Descriptive statistics identified factors affecting students' intent to stay or go. Chi-square analysis, and analysis of variance (ANOVA) identified differences between factors based on students' intent to stay or go, and identified differences based on …

Signaling Instructional Video For Mathematics, Kimberly W. Milner

STEMPS Theses & Dissertations

Video provides an increasingly valuable medium for delivery of instruction in a growing number of content areas. Growth of online instructional applications has been prompted by expansion of the Internet and video streaming technology, adding to the need for design practices that produce more effective and efficient instructional videos. This study examined the use of signaling for multimedia to reduce cognitive overload and increase mental effort when learning mathematical concepts and procedures from instructional video. Signaling addresses the issue of directing the learner's attention by using visual or verbal cues that stress importance and organization (Mayer, 2009). Effectively signaled instructional …

A Model Of Responses To Race-Based And Gender-Based Stereotype Threat In Computer Science, Lara Tedrow

Psychology Theses & Dissertations

The perception of stereotype threat among computer science students was examined at two universities. A model of stereotype threat was developed and tested among students enrolled in three undergraduate computer science courses at two universities. The goal of this model was to provide an understanding of the underlying mechanisms through which stereotype threat works.

The study tested relationships among the following variables: race-based stereotype threat, gender-based stereotype threat, goal orientation, CS self-efficacy, active coping, behavioral disengagement, effort, and performance. Structural equation modeling was used to test the measurement model and a series of nested structural models. Findings supported the proposed …

Motivation And Performance In Computer Science: Test Of An Integrative Theory, Katherine A. Selgrade

Psychology Theses & Dissertations

The purpose of this study was to design and empirically test a parsimonious integrative motivation theory. The theory integrates aspects of expectancy theory, social cognitive theory, goal-setting theory, and commitment theory. The theory was tested with 170 undergraduate, students in an introductory computer science (CS) course.

The study tested relationships among the following variables: CS self-efficacy, mathematics ability, affective commitment to the CS class, goal orientation, effort, and performance. The study also tested the interactive effects of effort and ability on performance. Structural equation modeling was used to test the measurement model and a series of nested structural models. Findings …

The Effect Of Same-Sex Grouping Versus Mixed-Sex Grouping On Mathematics Achievement And Attitudes Of Academically Gifted Fourth And Fifth Grade Females In The Urban Classroom, Martha J. Tompkins

Theses and Dissertations in Urban Studies

Reports of the neglect of gifted students in America's schools and the inadequate mathematics involvement of females have made educators aware of a crisis in public education. Attitudes and opportunities are believed to be major influences in helping females become more involved with mathematics courses and careers. The research project examined the effect of same-sex groups versus mixed-sex groups on mathematics attitudes and achievement in fourth and fifth grade females in a mathematically gifted pilot program at a magnet center. The experimental study was analyzed with Multivariate Analysis of Variance (MANOVA), Analysis of Variance (ANOVA), Regression Analysis, Post-Hoc tests, and …
