This convergent mixed methods study sought to explore the effects of engineering design challenges (EDCs) on middle school students' achievement. Data was collected from four middle schools from an urban school district in Maryland. Two of these, Group A, included teachers with experience with EDC design and implementation; the other two schools,…

Each year, in middle and high school classrooms, secondary science teachers introduce their students to the periodic table of elements (herein the periodic table). According to the Next Generation Science Standards (NGSS Lead States, 2013), one of the performance expectations states that high school students should be able to, "Use the…

The purpose of this study was to, first, examine the potential of lesson plans (LPs) of preservice science teachers (PSTs, N = 631) as a source for gathering rich data on their pedagogical content knowledge (PCK) and, second, qualitatively describe PSTs' reasons for the level of data richness in their LPs on PCK. PSTs' handwritten LPs were…

The purposes of this study were to explore how a science teacher and a mathematics teacher collaborated for science and mathematics integration with the support of a researcher, to describe the process of planning and implementing integration and to understand the main issues considered by teachers during the process. Observational case study was…

With the implementation of Next Generation Science Standards, educators shifted from lecturer to facilitator using inquiry-based learning approaches. Teachers may express anxiety about this role reversal in providing scientific instruction. This study addressed conflicting perspectives in the implementation of inquiry-based learning approaches as…

This qualitative action research study examines how middle and high school STEM teachers create and implement lessons that connect concepts to the real-world and develop student metacognition. The researcher collected data through interviews, focus groups, document analysis, and survey questions. Participants from vocational, private, and…

The current study examined the effects of a nationally scaled up Professional Learning and Development (PLD) model on teachers' classroom implementation of the Geospatial Inquiry instructional framework. Geospatial Inquiry is defined as: asking and answering a research question through the analysis and communication of data that is linked to a…

Science learned requires constructivist experiences so that students could learnt to discover and conclude. However, today's learned challenges were increasing along with the diversity of students and interests. The aimed of this researched was to increase the knowledge and practiced of prospective science teachers in didactic practiced through…

The study aimed to explore the integration of lesson study into science teacher education programs to enhance preservice science teachers' pedagogical content knowledge (PCK) for STEM. The lesson study cycle encompassed planning, teaching, reflecting, re-teaching, and re-reflecting phases, and the participants' experiences regarding PCK for STEM…

Sixth-grade science students at Gauger-Cobbs Middle School in Newark, DE, had misconceptions about how heat energy moves in the hydrosphere through conduction, convection, and radiation. As a result, students struggled to develop and connect ideas that correctly and completely explained heat transfer in the hydrosphere at the end of the lesson…

Despite national curricula and instructional reforms calling for collaborative problem-solving skills (CPS), however, there is an absence of a theory-laden model showing how to effectively construct CPS for science learning. We therefore developed and validated a simulation-based CPS model that exploits its constructs, sequences, and causal…

Learn about the Challenge Based Science Learning Project and its larger implications for the fields of Next Generation Science Learning and Open Educational Resources. The project involved 18 middle school teachers and five administrators from three U.S. school districts partnering with instructional coaches and learning sciences researchers from…

We present an empirically based model for teaching about planning in pre-service science teacher education as part of on-campus courses. Planning is usually taught through the introduction of theoretically based planning models, but these models commonly assume a linear idea of planning that does not match how teachers go about planning. We…

Students in the middle grades are expected to read complex texts to acquire content knowledge, particularly in social studies/history and science. Most students with disabilities are included in social studies/history and science classes and yet read below grade level, requiring significant support with accessing text knowledge. Question…

This study aims to investigate the effect of Toulmin argumentation model (TAM), epistemologically enriched Toulmin argumentation model (EETAM), and method suggested in Turkish Science Curricula on the epistemological beliefs of 7th grade students and their views on this effect. In this context, while the students in TAM group learned seventh grade…
