Uncertainties are inherent in education as learners encounter gaps in their awareness of topics, receive new information that potentially conflicts with prior understandings, and grapple with known unknowns in order to construct new knowledge. While researchers have shown that students productively struggling with problematized and uncertain…

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,…

This quasi-experimental study aimed to determine if there is a statistically significant difference in student test scores when a modified instructional sequence in middle school science is used versus the instructional sequence suggested by the Commonwealth of Virginia. The Grade 8 science cumulative Standards of Learning (SOL) test results from…

Traditional science instruction typically follows an initiation- response-evaluation format and privileges curriculum reflective of Western, male, white, middle-class values, and knowledge which sometimes tends to exclude Black and Latinx students. This qualitative instrumental case study explored how a White male seventh-grade science teacher in…

An instructional focus on Science, Technology, Engineering, and Math (STEM) is a current popular educational due to the widespread need for skilled workers in these growing fields. Compounding this labor shortage is the fact that female students and workers are underrepresented in STEM subjects. The purpose of this study was to examine the…

The purpose of this study was to determine how a particular technology program, Gizmos, would impact English language learner students in demonstrating their verbal and written comprehension of science content at a proficient level. Gizmos were incorporated as an intervention to facilitate the teaching of two different topics, convection cells and…

Co-teaching is a progressive approach to teaching using an inclusive model where all students experience the same lesson while receiving individualized resources to meet personal learning needs. The purpose of this case study was to examine one school district's transition from resource rooms to inclusion using the co-teaching model. The middle…

In 2019, the U.S. is still facing a shortage of science, technology, engineering and mathematics (STEM) workforce that is capable of solving social and economic challenges in 21st century worldwide. Numerous studies have explored the influence of integrative STEM approaches on developing student interest and career aspiration in STEM. Building on…

Nebraska is committed to pursuing a new vision for science education based on "A Framework for K-12 Science Education" (NRC, 2012), that advocates for rigorous, high-quality science education for all students. Following an ambitious four year timeline, Nebraska is working to develop new assessments aligned to and designed for these…

Although using images for teaching has been a common practice in science classrooms (Gordon & Pea, 1995) understanding the purpose or how to choose images has not typically been intentional. For this dissertation three separate studies relating to choosing and using images are prepared with environmental science in mind. Each of the studies…

This dissertation addresses the complexity of test illustrations design across cultures. More specifically, it examines how the characteristics of illustrations used in science test items vary across content areas, assessment programs, and cultural origins. It compares a total of 416 Grade 8 illustrated items from the areas of earth science, life…

The purpose of this three-paper manuscript dissertation was to study digital fabrication as an instructional technology for supporting elementary and middle school science and mathematics education. Article one analyzed the effects of digital fabrication activities that were designed to contextualize mathematics education at a summer mathematics…
