As students with autism spectrum disorder (ASD) participate in the general education setting at greater rates, they are expected to meet rigorous grade-level academic standards. Students with ASD typically struggle with problem solving, higher-ordered thinking, and mathematical reasoning. When students enter middle school, mathematics becomes more…

There have been many attempts to address the deficits in traditional teaching methods for decades Multiple studies have been done on the Common Knowledge Construction Model (CKCM) and the results of each study has shown an improvement. The addition of relational conceptual change has added much needed improvement in teaching science. This study,…

Spatial skills, which represent the ability to mentally manipulate objects (Schneider & McGrew, 2012; Atit et al., 2020) have been shown to be correlated with entrance, persistence and success in STEM (Shea et al., 2001; Wai et al., 2009). Specifically, these skills have been shown to be necessary to geologists and geoscientists (Hegarty,…

The purpose of this mixed methods multiple case study was to gain insight into the self-efficacy beliefs of pre-service teachers participating in a curriculum enhanced via mixed reality simulation experiences. There were two cases within the present study, one was bound by pre-service teacher candidate participants enrolled as students within one…

Formative assessment has long been used to gauge students' understanding of course material prior to taking an exam. With the advent of more advanced technology, only recently have instructors been able to combine formative assessment with a student response system to allow students to respond to questions in real time during class. Previous…

Review of the history of trigonometry content and pedagogy indicates the necessity and importance of trigonometry in the school curriculum (e.g., van Brummelen, 2009; van Sickel, 2011). For example, understanding trigonometric functions is a requirement for understanding some other areas of science, such as Newtonian physics, architecture,…

Algebra is the foundational mathematics course that students take as they begin their high school career and is often difficult for the average learner. In order for students with disabilities and those with mathematics difficulties to meet the high expectations of future mathematical courses, providing quality instruction by implementing…

In response to both nationwide calls for reform and a perception that the existing chemistry curriculum was not meeting the needs of life science students, faculty in the department of chemistry at Purdue created a redesigned chemistry course sequence specifically aimed at preparing biology majors. The new sequence, called the 1-2-1 curriculum,…

Worked-out examples are a common teaching strategy that aids learners in understanding concepts by use of step-by-step instruction. Literature has shown that they can be extremely beneficial, with a large body of material showing they can provide benefits over regular problem solving alone. This research looks into the viability of using this…

Despite the growing attention being paid to teaching mathematics for students with disabilities, the existing research tends to focus on mathematical skill acquisition, but not on skill maintenance. Maintenance of mathematical skills is especially important as mathematics has applications in daily life and is directly related to important life…

This sequential explanatory mixed methods study investigated 24 college and university syllabi for content consisting of multicultural education that used the framework for multicultural education devised by James A. Banks (2006). This framework was used to analyze data collected using descriptive statistics for quantitative phase one. The four…

Electrochemistry is the area of chemistry that studies electron transfer reactions across an interface. Chemistry education researchers have acknowledged that difficulties in electrochemistry instruction arise due to the level of abstraction of the topic, lack of adequate explanations and representations found in textbooks, and a quantitative…

Are potential relationships among students' learning styles and effectiveness in online education moderated by subject matter for undergraduate students at a private higher education institution? This causal relationship correlational study evaluated the effects of subject matter as a moderating variable between students learning styles and…

This dissertation presents the findings of an on-line survey completed by 222 FYC (First Year Composition) instructors at universities and community colleges across the United States along with supplemental information derived from multiple open-ended interviews with seven FYC instructors in Arizona. Both survey and interview questions were…

This study investigated the rate of success for IT projects using agile and standard project management methodologies. Any successful project requires use of project methodology. Specifically, large projects require formal project management methodologies or models, which establish a blueprint of processes and project planning activities. This…
