Reading proficiency is particularly crucial for adolescent students who are expected to adopt and approximate a multitude of authentic literacy practices in several different content areas within the span of a single school day. A large number of adolescent students are failing to master basic levels of reading, and are thus uniquely disadvantaged…

As K-12 schools in the United States continue to experience increases in enrollment of English learners (ELs), educators and researchers seek to identify effective teaching practices. Previous research in the area of teacher effectiveness with ELs has focused mainly on pre-service and elementary-level teachers, with studies of coursework and…

This quantitative study examined the impact of a multi-subject double-dose STEM intervention on the academic achievement of underprepared 9th-grade males. The intervention consisted of heterogeneously grouped core classes of Algebra 1 and biology accompanied by a second multi-subject (Algebra 1 and biology) support class. This nine-week study did…

A central aspect of reform-minded mathematical teaching is training and developing teachers' ability to notice vital aspects in the classroom and more specifically, students' mathematical thinking. As there is an abundance of evidence and research that support the benefits for teachers to elicit and use students' ideas and thinking during…

In an increasingly data-driven society, making decisions with data is a requirement not only for research scientists but also for navigating life more generally (Kjelvik & Schultheis, 2019). An informed citizenry must be prepared to discover patterns, predict outcomes, make decisions with data, and evaluate data-based claims for legitimacy and…

Undergraduate general chemistry courses are often perceived in a negative light by students. Student attitudes towards chemistry play a significant role in their success in chemistry and retention in STEM altogether. Research has shown in K-12 classrooms that care-based instruction strategies can help to improve student attitudes towards…

This dissertation explores the implementation of classical education in a non-classical charter high school, with a focus on science education using classical methodologies. Employing techniques like copy work, history-based science teaching (HBST), the Socratic method, and the Progymnastmata, astronomy, and chemistry were taught. To identify…

This study addressed the following research questions: 1) What is the effect of differentiated gamified instruction on the cognitive engagement of ninth grade students in the unit of plant and animal systems? 2) What is the effect of differentiated gamified instruction on the behavioral engagement of ninth grade biology students in the unit of…

The paper describes the intent, process, and findings in implementing an online Indigenous People's Social Studies curriculum that incorporates what local cultural institutions have to offer. Constructivism is the main theory embedded with Community of Inquiry, New Museum Theory, and Indigenous New Museum Theory. Subsequent pages describe planning…

When instructing very large groups of students in science, it can be difficult to engage all students in the content and measure their understanding. A major unaddressed challenge in science instruction is how specifically to design and implement strategies that engender active learning particularly in high-enrollment undergraduate courses. Active…

Spatial skills, the set of cognitive skills that are responsible for our understanding of objects in real and imagined spaces, have been identified as a potential gate-keeper for STEM success. Because of the recent emphasis on improving education to prepare for the increasing demand for workers in STEM fields, there is a rising interest in…

The purpose of this mixed methods, qualitative and quantitative study was to explore how math and science teachers perceived and supported the learning of students with high abilities in inclusive, urban, general education classrooms. Drawing on the literature on self-regulated learning (SRL), the study explored: (1) teachers' perceptions of…

Purpose and Method of Study: The purpose of this study was to compare the effectiveness of two approaches to professional development methodologies implemented in public schools. A quantitative, correlational research design was employed to determine whether the academic success in the core content areas of reading, writing, math and science could…

Computational thinking (CT) has great potential for enhancing mathematics and science lessons in K-12 education. Numerous studies demonstrate that under the right circumstances, CT integration in math and science can improve student learning and promote deeper understanding. However, teacher education currently does not include preparation for…

Global climate change (GCC) presents unprecedented global concerns, notably food supply limitations, unsustainable use of natural resources, and widespread environmental degradation. The International Panel on Climate Change (IPCC) reports a 0.85 °C increase in global average temperatures between 1880 and 2018 and a 50% increase in global carbon…
