This study aimed to determine the perceived value and frequency of singing, chanting, and additional vocalization techniques in school instrumental ensembles. Vocalization tools are meant to enhance student musicians' concepts of music. Music directors, both band and orchestra, in a southeastern American state completed a questionnaire that asked:…

Mathematical cognitive technology tools, such as Desmos, have the capacity to provide rich mathematical experiences for students (Bos, 2009; Dick & Hollebrands, 2011). To maximize the benefits of MCTs, teachers must believe the technology will help students understand mathematics and be skilled at using the technology (Doerr & Zangor,…

The intent of this study was to address a problem of practice in an elementary school setting in order to provide opportunities for students with significant impairments to be educated in the least restrictive environment. Three research questions guided the study: How effectively has Be Your Best Elementary School (BYBES) developed and…

Mathematics education research has failed to investigate Queer students' experiences in high school mathematics. In addition, research has also failed to include the voices of Queer high School students when they are the foci of research discussions. However, research has emphasized and incentivized the implementation of the Teaching of…

This dissertation investigated the relationship between mindset and self-efficacy among special education teachers in Region 2 of Texas. While approximately 500,000 students are provided special education services in Texas public schools, special education students perform significantly lower on state assessments in reading and math than their…

Methods of teaching differential equations (DE) have long focused on rote analytic solution methods that align poorly with more industry-relevant numerical and computational methods. Engineering and mathematics educators agree that there is a need to shape DE curricula to reflect the mathematical practices of the disciplines whose students take…

This paper reports on an experiment involving 108 sixth-grade French students in which the history of Chinese numeration was used in mathematics education. The aim of this study is to evaluate the relevance of using ancient number systems in mathematics education, which is common in French textbooks. In the experiment a pre-test with usual…

To construct dialogue-based Intelligent Tutoring Systems (ITS) with sufficient pedagogical expertise, a trendy research method is to mine large-scale data collected by existing dialogue-based ITS or generated between human tutors and students to discover effective tutoring strategies. However, most of the existing research has mainly focused on…

An issue in education today is the lack of effective teaching methods for immigrant and emergent bilingual students. Mathematics teachers of students that speak English as a second language face particular challenges because of the complexities of math vocabulary words, which may bring more confusion. My study examines methods one secondary…

A national survey of chemists (n = 174) explored the self-reported format and focus of postsecondary inorganic chemistry instructional laboratory curricula. Multiple instructional laboratory course formats were observed, including stand-alone inorganic chemistry instructional laboratory courses, inorganic chemistry laboratory instruction as a…

The use of interlocking toy building blocks (e.g., LEGO) as teaching modules with a focus on the topics in organic chemistry is presented. Interlocking building blocks were assembled on a baseplate to depict chemistry concepts of hydrogenation of alkenes, hydration of alkenes, Markovnikov's rule, cis and trans isomers, hydrogen bonding, optical…

Team-based learning (TBL) is a research-based instructional practice (RBIP) shown to increase students' content knowledge, class engagement, motivation, and science self-efficacy. After several years of using TBL in an upper-division biochemistry course and noting the same positive effects, we were hesitant to abandon TBL when forced to consider…

The process of method development is at the heart of analytical chemistry, yet direct experimental experience with the process is rarely taught in the undergraduate laboratory. We report here an experiment that uses rapid, safe, and inexpensive paper-based microfluidics with cell phone detection in order to facilitate the development of a…

Online literacy learning is still a relatively new field, however, with the advent of the COVID-19 pandemic in 2020, online learning became the primary mode of instruction for millions of students in public, charter, and private schools. This descriptive content analysis seeks to identify trends within the field of online literacy instruction from…

Rooted in Chicana/Latina feminism and interdisciplinary frameworks, this dissertation uses autoethnographic (Behar, 1996), participatory (Baquedano-Lopez, 2021; Irizarry & Brown, 2014), and art-based research (Leavy, 2015; Delgado Bernal, Burciaga & Flores Carmona, 2012) to document Mexicana/Latina campesinas' education in agriculture in…
