Gender Differences In High School Students’ Perceived Values And Costs Of Learning Chemistry, Xiaoyang Gong, Bradley W. Bergey, Ying Jin, Kexin Mao, Yan Cheng

Publications and Research

Students’ perceived values and costs of learning chemistry influence their performance and intentions of choosing chemistry-related majors or careers. Based on Situated Expectancy-Value Theory, this study adopted a mixed method approach to examine the conceptualization of values and costs among Chinese high school students and identify their relations with chemistry test performance across gender. Qualitative content analyses revealed that students’ perceived values for chemistry could be categorized into five broad categories: utility value, epistemic value, intrinsic value, aesthetic value, and social value. Chi-square tests and multidimensional scaling revealed that boys and girls perceived values and costs in different ways: relational …

Surveillance And Monitoring Of Amphibian Pathogens And Evaluating The Impacts Of An Associated Course-Based Undergraduate Research Experience (Cure), Jennifer Perez Jan 2023

Surveillance And Monitoring Of Amphibian Pathogens And Evaluating The Impacts Of An Associated Course-Based Undergraduate Research Experience (Cure), Jennifer Perez

EWU Masters Thesis Collection

Amphibians are a highly diverse class of vertebrates and crucial for natural ecosystems, inhabiting both aquatic and terrestrial environments at different life stages. However, amphibians are facing devastating declines largely due to the disease chytridiomycosis, caused by the fungal pathogens Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal). This disease can lead to population declines, biodiversity loss, and species extinction. However, resources to study and mitigate this disease are limited and an opportunity to assist in these efforts has been created in the form of a course-based undergraduate research experience (CURE). Chapter 1 of my thesis used Roger's Diffusion of Innovations …

Identifying Potential Consequences Of Use Of A Measure Through Stakeholder Interviews, Melissa G. Kuhn, Joanna K. Garner, Shanan L. Chappell, Linda Bol Jan 2023

Identifying Potential Consequences Of Use Of A Measure Through Stakeholder Interviews, Melissa G. Kuhn, Joanna K. Garner, Shanan L. Chappell, Linda Bol

STEMPS Faculty Publications

The advent of Messick’s Contemporary Validity Theory (1994) led researchers in survey and measure design to develop and standardize qualitative and quantitative methods of collecting evidence for the validity of psychological instruments. However, one aspect of this theory, consequential validity, has few agreed-upon evidence-gathering methods (Furr & Bachrach, 2014). This study added a blueprint-driven interview method of collecting forecasted consequences of use of an instrument into the overall process of developing a measure of outreach impact on undergraduate engineering students (Authors, in press). The method, which included a purposeful sampling of end-users, is illustrated with thematically presented results. Potential implications …

School Library Advocacy: Enhancing Opportunities For All Learners, Elizabeth A. Burns Jan 2023

School Library Advocacy: Enhancing Opportunities For All Learners, Elizabeth A. Burns

STEMPS Faculty Publications

There is a lack of consistency in how school librarians understand and engage in advocacy for their programs and the profession (Burns, 2015; Lance & Kachel, 2018). It is important that school librarians demonstrate the positive impact they contribute to improving instruction for student learners and advancing access so that all learners have equal opportunities. The school library and school librarian should be available to each student (Kachel, 2021). The School Library Manifesto (2021) includes language to support a strong school library with a qualified school librarian. Advocacy goals can be highlighted throughout this critical set of school library guidelines. …

Impact Of Designed Task-Based Interventions On K-8 Preservice Teachers’ Knowledge And Ability To Solve Measurement Unit Conversion Problems, Ha Nguyen, Tuyin An, Eryn Maher Jan 2023

Impact Of Designed Task-Based Interventions On K-8 Preservice Teachers’ Knowledge And Ability To Solve Measurement Unit Conversion Problems, Ha Nguyen, Tuyin An, Eryn Maher

Mathematical Sciences: Faculty Publications

Converting two-dimensional measurement units presents challenges for K-8 preservice teachers (PSTs) (e.g., 9 ft2 = __ yd2). Place value deficiency, lack of understanding of metric system measurement units, misconceptions about relationships between measurement units, and uncertain knowledge of ratios have been identified as causes of student error in one-dimensional analysis (e.g., Livy & Vale, 2011; Morris, 2001; Southwell & Penglase, 2005). However, PSTs’ strategies for solving two-dimensional measurement unit conversion problems (MUCPs) and possible interventions for improvement are rarely investigated in research. The purpose of this study is to design and test a set of tasks that may help students …

Enrollment In Science, Technology, Engineering, And Math Courses After Enactment Of Texas' House Bill 5, Carlana Cla'shette Allen

Walden Dissertations and Doctoral Studies

Student participation and performance in science, technology, engineering, and math (STEM) have been an education concern in the United States for years. In 2013, Texas lawmakers passed House Bill 5 (HB5) to support increases in STEM awareness, particularly among ethnic minority and female students. To date, no studies have been conducted on the impact, if any, of HB5 on Texas high school students’ course selections in STEM areas. Further, it is unknown whether the impact that does exist is equally distributed across socioeconomic status (SES), race/ethnicity, and gender groups. The purpose of this nonexperimental correlational quantitative study was to determine …
