This journal-ready dissertation contains three articles related to the developmental mathematics redesign at Chandler-Gilbert Community College (CGCC). The first article covers background information related to the Maricopa Community College District (MCCCD) sponsored initiative from Fall 2011 through implementation at CGCC in Fall 2017. The…

Teachers' professional development is an important factor to improve the quality of teaching in colleges and universities. At present, teachers' professional development in colleges and universities mainly focuses on teacher training and consultation, lacking personalized attention to teachers' professional development. With the development of…

Research on school districts has repeatedly found that focusing on student learning and instructional leadership is a key component to effectiveness (Murphy & Hallinger, 1988; Leithwood, 2010; Anderson & Young, 2018). Districts are currently undergoing a redefinition of roles in order to specifically support principals as instructional…

Math anxiety is a problem in the United States which impacts 93% of the population including elementary teachers. Since elementary teachers can pass their math anxiety onto their students, it is important that they reduce their own math anxiety. If time were taken to develop the math identity of elementary school teachers, would it reduce math…

An introductory normal phase column chromatography experiment is described and evaluated for second year undergraduate chemistry laboratory class. The experiment involves a nucleophilic substitution yielding a crude mixture of reactant and one product, both of which are brightly colored and contrasting, creating a clearly visual separation when…

This study was aimed to explore Chinese college and university students' motivations to study abroad and examining how their career aspiration influence their decision-making process. 5 research questions were developed from this research topic. A qualitative phenomenological methodology was applied. The researcher himself and the face-to-face…

Retention of students' attention in general chemistry courses stands as one of the main challenges that educators are facing in classes of any size and is especially prevalent with classes composed of mixed majors. Herein, we describe our experience with introducing short, 10 min student lectures ("flash talks") on popular chemistry…

Instrumentation plays a critical, ubiquitous role in modern chemistry. The undergraduate chemistry curriculum must therefore cultivate students' ability to investigate chemical phenomena via relevant instruments. The instructional laboratory serves as the primary context in which undergraduates learn about instrumentation, where use of instruments…

FINDIF is a Windows application that numerically solves the one-dimensional (1D) Schrödinger equation and displays the eigenstates, eigenvalues, and probability density of the system. FINDIF accepts both nonperiodic and periodic 1D potential energy functions as input and uses the finite difference method to evaluate the energy of the quantum…

This research developed learning activities for students to explore and connect the concepts of acid-base titration, equivalence points, pK[subscript a], and molar absorption coefficients. Polyphenolic compounds consisting of p-coumaric acid (CMA), caffeic acid (CFA), and 3,4,5-trihydroxycinnamic acid (3,4,5-THCA) were selected as study models.…

A drug discovery project has been successfully implemented in an advanced undergraduate organic chemistry laboratory. In the laboratory, a five-step synthetic sequence is used to prepare five analogues of 13-phenyl-1-tridecanol. These compounds are key precursors in the synthesis of 2-oxo-14-phenyltetradecanes. This class of compounds, isolated…

A straightforward procedure for the synthesis of (Ph[subscript 3]P)[subscript 3]CuCF[subscript 3], a robust, air-stable trifluoromethylating agent, is reported herein. This preparation can be completed in a single 3 h laboratory session and typically provides ample yields (~79--86%) and high purity (>90%). The target complex is characterized by…

Objective: Collegiate-athletes are vulnerable to mental health disorders, such as anxiety and depression, yet very little is known about what variables might predict the use of on-campus mental health services among them. The purpose of this study was to investigate the utility of Andersen's Behavioral Model (ABM) in predicting the use of…

This study presents six teacher participants through a narrative inquiry that examined their teaching using inquiry-based instruction infused in global perspectives at various school settings from the following parts of the world: Malaysia, Wyoming, Maine, South Korea, Austria, and Lebanon. This study involved all six participants to share their…

Human-Computer Interaction (HCI) research aims to make systems versatile, easy to use, and accessible for most people. While computer technologies have successfully remodeled and improved the learning process, students with vision impairment (SVI) are at a disadvantage due to the lack of accessibility to their learning tools. This research aims to…
