Adaptive Learning, as a new online learning environment, intends to individualize the learning experience for each individual learner. Adaptive Learning suffers many shortcomings, as the date of the publication of this dissertation, however, it is considered the next generation of the learning environment for at least the next twenty years;…

An online curriculum intervention focusing on electronic interactions structure and percent composition was developed using a modified Knowledge Integration design framework. A study was conducted to determine the effectiveness of the design and student perceptions of their experiences. A sample of 58 students enrolled in an introductory chemistry…

Undergraduate chemistry majors should be encouraged to consider chemistry-based solutions to issues that impact their daily lives as well as the lives of poor and marginalized populations worldwide. Some issues that disproportionately influence historically disadvantaged populations are also directly related to or could be impacted by chemistry.…

Recent reforms have introduced integrated science, technology, engineering, and math education (STEM) that has highlighted an interdisciplinary approach to train students as better problem solvers. In addition to STEM disciplines, art, language, and other disciplines integration are also stressed (STEM+). In this paper, a STEM+ (STEM + art +…

As the World Health Organization declared COVID-19 a global pandemic in March 2020, universities around the world reacted quickly by shifting classes online. To varying extents, this rapid change required chemistry teacher educators to rethink and redesign their units and delivery. Some teacher educators may have perceived this shift as a timely…

Our goal was to understand how students' chemistry learning environments changed and how students responded to the wholesale transition to online learning. We deployed surveys to students enrolled in nine undergraduate chemistry courses at all levels. Survey 1 was deployed 2 weeks post-transition (N = 208); Survey 2, a week before semester's end…

COVID-19 caught everyone by surprise, and the situation quickly escalated from epidemic to pandemic. By February 21, 2020, the first positive case was reported in Lebanon, and following that, by March 12, 2020, the decision to close all educational institutes was put into effect. Online learning is not an approved form of education in Lebanon,…

Polychlorinated biphenyls (PCBs) are a family of synthetic chemicals consisting of carbon, hydrogen, and chlorine atoms. PCBs have been produced commercially since 1929 in hundreds of industrial applications. Their continued production in the United States was phased out in the late 1970s, and strict disposal guidelines were regulated as adverse…

Today, science education demands preparation of scientifically literate people, emphasizing more the process of working with information than owning it. Such a task requires a deep understanding of pedagogical content knowledge by science teachers. This study focuses on revealing the beliefs of prospective chemistry teachers during their teaching…

Introduction: The emerging technology of three-dimensional (3D) printing has the potential to provide unique 3D modeling to support specific content in science, technology, engineering, and mathematics (STEM) education, particularly chemistry. Method: Seventeen (n=17) students with visual impairments were provided direct instruction on chemistry…

Research has shown that achieving gender equality in science goes beyond equal gender ratios in the classroom. Female students in science disciplines with relatively higher female participation rates (e.g. biology and chemistry) still experience similar gender issues as students in male-dominated science disciplines (e.g. physics and mathematics).…

The study aims to investigate the effect of context-based learning (CBL) on vocational high school students' chemical literacy of petroleum topics. Through quasi-experimental research with pretest-posttest design, 30 students from the automotive engineering program were assigned as the experimental group, while 31 students from the same school…

A qualitative pre-/post-test case study was conducted to explore the influence of inquiry-based education in eliciting learners' understanding of the particulate nature of matter in the gaseous phase. Two grade four classes (n=116) were conveniently and purposively sampled from two farm schools in Pretoria, South Africa. Data was collected through…

We previously reported that students' concept-building approaches, identified a priori using a cognitive psychology laboratory task, extend to learning complex science, technology, engineering, and mathematics topics. This prior study examined student performance in both general and organic chemistry at a select research institution, after…

Principal component analysis (PCA) is one of the most important and powerful methods in chemometrics as well as in a wealth of other areas. Running a PCA results in two main elements, the score plot and the loading plot; the score plot provides the location of the samples, and the loading plot indicates correlations among variables, the trends in…
