Breaking The Language Barrier: Equitable Assessment In General Chemistry, Eshani Lee May 2018

Breaking The Language Barrier: Equitable Assessment In General Chemistry, Eshani Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Because language provides the framework through which knowledge is constructed, it is crucial to consider the ways in which students with limited English proficiencies are able to express their understanding. English language learners (ELLs) make up a significant portion of the student body in the education system and represent many ethnic and racial minorities in STEM (Science, Technology, Engineering & Mathematics) fields (Burke & Mattis, 2007). Despite the national push to build a more diversified, STEM-ready workforce, there is little research that considers the way ELLs are assessed in STEM courses at the postsecondary level. Literature reports that science tests that assess ...

Structural Behavior Of Nbsexte2-X Superconductors Under High Pressure, Vahe Mkrtchyan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Niobium chalcogenide compounds have recently gained a great deal of interest due to the fact that a superconducting phase coexists with the charge density wave state (CDW), as well as their potential for numerous applications. Two superconducting compositions, NbSexTe2-x (x=2, 1.5) were prepared by solid state route using high purity Nb, Se, and Te powders. Powder X-ray diffraction patterns collected at ambient conditions for NbSe2 and NbSe1.5Te0.5 showed a single phase with hexagonal crystal structure, with space group P63mmc. High-pressure X-ray diffraction measurements were performed at the Advanced Photon Source at Argonne National Laboratory to investigate ...


Development And Testing Of An Assessment To Measure Spatial Thinking About Enhanced Greenhouse Effect, Heather Jean Skaza Aug 2016

Development And Testing Of An Assessment To Measure Spatial Thinking About Enhanced Greenhouse Effect, Heather Jean Skaza

UNLV Theses, Dissertations, Professional Papers, and Capstones

Americans, in general, do not behave in environmentally sustainable ways. We drive cars and fly in planes that emit planet-warming carbon. We purchase food in nearly indestructible packaging that is not recycled or repurposed. We do not consider the environmental impact of the “stuff” stuffed into our grocery and department stores, most of which is made of materials that had to be dug out of the ground, leaving rivers and skies full of pollution in its place. Citizens have a responsibility to understand complex global and local environmental problems. A person’s ability to think about the way that an ...

Is Being Green, White? A Critical Ethnographic Study Of Social Norms In Conservation, Heather Whitesides May 2016

Is Being Green, White? A Critical Ethnographic Study Of Social Norms In Conservation, Heather Whitesides

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attempts to measure and implement conservation norms have consistently upheld and promoted the dominant culture’s practices and beliefs. This has led to oppression of non-dominant populations, thereby hindering these populations’ access to various opportunities to participate in conservation based activities. This has historically, and still today, led to the segregation of non-dominant populations from environmental participation and has misrepresented their beliefs and actions relative to definitions of conservation citizenship and in the broader literature on conservation, conservation measurements, outdoor recreation, and pro-environmental behavior.

This research sought to extend the existing literature on conservation, specifically on the measurements of recreation ...

An online interactive tutorial instruction that implemented worked-examples and multimedia learning principles was developed for this study. A total of 147 high school students (ages ranging from 14 to 17) who were taking a Computer Introduction course participated in this study. The course was offered in ...


Estimation Of The Tax Rates Based On Vehicle Miles Traveled Using Stochastic Models, Pratik Verma Aug 2013

Estimation Of The Tax Rates Based On Vehicle Miles Traveled Using Stochastic Models, Pratik Verma

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this thesis, we shall study the alternative revenue collection system which is based on the vehicle miles traveled (VMT). In various studies, it has been found that the existing revenue collection system based on gas/fuel tax is not an appropriate option in the longer run. The main reasons include no effective tax process for vehicles based on alternative fuel vehicle, no effective changes in tax due to economical inflation, and more highway expenditure than generated revenue. Our main objective is to estimate the VMT tax rates that should be charged in order to generate same amount of revenue ...


Development And Validation Of The Biophilic Attitudes Inventory (Bai), Lawrence Letourneau May 2013

Development And Validation Of The Biophilic Attitudes Inventory (Bai), Lawrence Letourneau

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study investigated the viability of an instrument called the Biophilic Attitudes Inventory (BAI), a pen-and-paper instrument intended to measure attitudes toward nature that, according to naturalist Edward O. Wilson, are rooted in an innate predisposition that humans possess to connect with other forms of life. Utilizing confirmatory factor analysis (CFA), two models were tested (n=334)--a seven-factor model that reflected Stephen Kellert's biophilia typology and a more parsimonious two-factor model. However, neither model proved viable in terms of construct validity. As a result, a new model with four factors was developed via exploratory factor analysis (EFA). A ...


What Can Biochemistry Students Learn About Protein Translation? Using Variation Theory To Explore The Space Of Learning Created By Some Common External Representations, Thomas J. Bussey May 2013

What Can Biochemistry Students Learn About Protein Translation? Using Variation Theory To Explore The Space Of Learning Created By Some Common External Representations, Thomas J. Bussey

UNLV Theses, Dissertations, Professional Papers, and Capstones

Biochemistry education relies heavily on students' ability to visualize abstract cellular and molecular processes, mechanisms, and components. As such, biochemistry educators often turn to external representations to provide tangible, working models from which students' internal representations (mental models) can be constructed, evaluated, and revised. However, prior research has shown that, while potentially beneficial, external representations can also lead to alternative student conceptions.

Considering the breadth of biochemical phenomena, protein translation has been identified as an essential biochemical process and can subsequently be considered a fundamental concept for biochemistry students to learn. External representations of translation range from static diagrams to ...


Being Outside Learning About Science Is Amazing: A Mixed Methods Study, Michelle L. Weibel Dec 2011

Being Outside Learning About Science Is Amazing: A Mixed Methods Study, Michelle L. Weibel

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study used a convergent parallel mixed methods design to examine teachers' environmental attitudes and concerns about an outdoor educational field trip. Converging both quantitative data (Environmental Attitudes Scale and teacher demographics) and qualitative data (Open-Ended Statements of Concern and interviews) facilitated interpretation. Research has shown that adults' attitudes toward the environment strongly influence children's attitudes regarding the environment. Science teachers' attitudes toward nature and attitudes toward children's field experiences influence the number and types of field trips teachers take. Measuring teacher attitudes is a way to assess teacher beliefs.

The one day outdoor field trip had significant ...

Assessing The Effect Of Simulation Models On Systems Learning In An Introductory Environmental Science Course, Heather J. Skaza Apr 2010

Assessing The Effect Of Simulation Models On Systems Learning In An Introductory Environmental Science Course, Heather J. Skaza

UNLV Theses, Dissertations, Professional Papers, and Capstones

While there is plenty of anecdotal evidence within the systems dynamics community supporting the use of systems simulations in the classroom to improve student understanding, there is little published, controlled, experimental research. This paper describes the results of a paired experiment testing the effect of using system dynamics simulations to increase systems understanding in an introductory environmental science course. We believed that the students using the systems simulations would demonstrate a greater systemic understanding of environmental issues than those who did not.

We conducted an experiment during the fall semester of 2009, with 304 students enrolled in four sections of ...


The Impact Of Individual Decision Making On Campus Sustainability Initiatives, Aurali Ella Dade Apr 2010

The Impact Of Individual Decision Making On Campus Sustainability Initiatives, Aurali Ella Dade

UNLV Theses, Dissertations, Professional Papers, and Capstones

Institutions of Higher Education (IHEs) have increasingly committed to become more sustainable in recent years. Despite this commitment, academic publications in the sustainability field assert that progress has been slower at IHEs than expected and that most IHEs have found sustainability initiatives difficult to implement. Comprehensive sustainability initiatives require cooperation from a broad set of constituents with diverse and sometimes conflicting goals. Creating a sustainable IHE also requires changes in both physical infrastructure and individual behavior. Any number of institutional factors can advance or limit progress towards these objectives.

Previous investigations have assessed individual case studies, compared IHEs in a ...

Innovations In Reuse, Lisa R. Osorio

UNLV Theses, Dissertations, Professional Papers, and Capstones

Material reuse benefits all sectors in the community by decreasing the amount of reusable solid waste that is discarded. It increases the resources available for various programs and builds partnerships with educators, and businesses to support and promote reuse programs that will improve the quality of life in areas in which they operate. Several areas of the country currently have reuse programs that focus on several areas of reuse. Successful projects in several cities have focused on such areas as reuse for education, the arts, or other nonprofit activities. These sustainable programs have benefited other communities and should serve as ...
