This three-manuscript dissertation used a rapid PDSA to improve teacher efficacy concerning designing and teaching an unleveled 9th grade science class. Leveling and tracking can lead to inequitable outcomes and experiences for minoritized students. However, designing and implementing effective heterogeneous, unleveled classes that meet the needs…

Purpose: In U.S. public schools, principals must implement reforms that require instructional leadership across subjects, though little is known about subject-specific supervision. Methods: Through interviews with 26 K-8 principals, we examine instructional leadership for science. Findings: Our findings showed that science supervision occurred…

The goal of this research was to test the effectiveness of a new science curriculum focused on increasing awareness and knowledge of microplastic pollution in middle school students. The curriculum utilized three teaching methods including lectures, object-mediated learning, and peer collaboration to enhance student engagement and learning. The 84…

Society is increasingly dependent on science and technology. STEM careers are growing at rates faster than the general economy. STEM careers require individuals with advanced training in science, technology, engineering, and mathematics (STEM). The study of physics is a gatekeeper on the path to these challenging and rewarding STEM careers. One…

Background: Nanotechnology, a multidisciplinary field with increasing societal importance, demands for an increase in research abilities and capacities. Yet, nanoscience and nanotechnology (NST) are largely inaccessible to K-12 students. This situation demands efforts in research towards bringing NST learning into K-12 classrooms. Purpose: The…

Given the widespread adoption of the Next Generation Science Standards in the United States, there is a need to study new models of professional development to prepare teachers to enact practice-based visions of science learning and to address problems of access to reach teachers nationwide. While studies of online professional development offer…

Purpose: This paper aims to describe the design and user testing of GeoForge, a multiple-player digital learning experience for middle school that leverages virtual reality (VR) and individualized websites for learning concepts in planetary science. This paper investigates how specific instructional design choices and features of the technology…

This study finds that, breaking with decades of slow improvement, U.S. reading and math scores on the National Assessment of Educational Progress (NAEP) and other assessments have seen historic declines since most states implemented national Common Core English and math curriculum standards six years ago. This descriptive analysis is designed to…

The problem of practice being explored in this work was first identified at a suburban middle school in Massachusetts, where the assessment scores of students with learning disabilities were significantly lower than those of peers not on Individualized Education Plans. The collaboration between general education science teachers and special…

A tension in designing classroom learning involves balancing the questions and interests of students with the goals of teachers and standards. One approach to navigating this tension in science classrooms is to simultaneously support and constrain students' questions about an observable natural phenomenon in the classroom and then take up those…

The Massachusetts Department of Elementary and Secondary Education (DESE) released proposed Science and Technology/Engineering standards in 2013 outlining the concepts that should be taught at each grade level. Previously, standards were in grade spans and each district determined the method of implementation. There are two different methods used…

Participation in inquiry-based science education, which focuses on student-constructed learning, has been linked to academic success. Whereas the benefits of this type of science education are evident, access to such high-quality science curriculum and programming is not equitable. Black and Latino students in particular have less access to…

This study investigates how students who are peripherally positioned in computer science-based, collaborative group work meaningfully engage with the group activity in order to learn. Our research took place in the context of a one-day, all-girl robotics workshop. This work proceeds from the premise that learning about programming is mediated most…

Many national policy documents underscore the importance of 21st century skills, including critical thinking. In parallel, recent American frameworks for K-12 Science education call for the development of critical thinking skills in science, also referred to as science inquiry skills/practices. Assessment of these skills is necessary, as indicated…

There are well-acknowledged challenges to scaling computerized performance-based assessments. One such challenge is reliably and validly identifying ill-defined skills. We describe an approach that leverages a data mining framework to build and validate a detector that evaluates an ill-defined inquiry process skill, designing controlled…
