This study explored K-12 teachers' understanding and implementation of the Next Generation Science Standards (NGSS) during and after participation in a professional development (PD) program that included the development of science teachers' conceptual understanding of science. We add to the literature with our focus on a multi-year PD program…

Teacher education programs need to prepare their preservice teachers to both implement current science education reforms and teach in culturally and linguistically diverse classrooms. In this qualitative study, we used a framework of four instructional principles to investigate 31 preservice secondary science teachers' understanding of instruction…

Course-based undergraduate research experience (CURE) exposes an entire class of students to scientific research and is thought to increase students' knowledge retention in science, technology, engineering and mathematics education. Microbial engineering is an interdisciplinary subject that combines science and engineering. We transformed a…

One of the most challenging tasks for teachers in projects is to develop creative ideas. Due to the linear system perspective of education, fostering students' creativity is restricted. However, engineering design and scientific process skills that comprise creativity have an iterative structure. An iterative process-oriented education enables…

Generative AI technologies such as large language models show novel potential to enhance educational research. For example, generative large language models were shown to be capable of solving quantitative reasoning tasks in physics and concept tests such as the Force Concept Inventory (FCI). Given the importance of such concept inventories for…

The paper reports about a study that examines changes in teachers' incorporation of epistemic practices in their design of engineering lessons and compares them to their views about the nature of engineering knowledge across 100 hours of professional development. Nineteen K-8 teachers in the USA, who were new to teaching engineering as part of a…

Background: The Next Generation Science Standards (NGSS) call for the integration of engineering content and practices in elementary science curricula, yet little is known about elementary teachers' preparedness to do so or their views on teaching engineering. Purpose/Hypothesis: The purpose of the current study was to explore K-5 teachers'…

In this work we present the application of design based research (DBR) methodology to conduct a systematic iterative study of the design and implementation of a teaching-learning sequence (TLS) on emf (electromotive force). This work is the final part of a broader study that started with the analysis of students' difficulties with emf in the…

This paper investigates the viewpoints and perspectives of 179 undergraduate students engaged in a co-creation project regarding their anticipated progress, exploring, simultaneously, the affecting factors. The students attended the physics course in the Department of Industrial Design and Production Engineering at the University of West Attica,…

The onset of the Next-Generation Science Standards [NGSS] has created a need for elementary teachers to develop purposeful, multi-dimensional formative assessments (FAs). In order to promote this process, we utilized teacher learning communities (TLCs) and practice-based professional development focused on key aspects of the reform while…

Introducing abstract concepts to students from applied fields can be challenging. Electromagnetics is one of those courses where abstract concepts are introduced. This work presents a conceptual model which defines learning objectives in three levels for Engineering Electromagnetics. Each level is aligned with its own assessment and evaluation…

Since 2013, a majority of states have been working to implement new standards for K-12 science education that are based on the National Research Council's framework for science education and the Next Generation Science Standards. The new science standards emphasize deeper understanding of content in relation to practices and a three-dimensional…

This multiple case study focused on the implementation of a computer-aided design (CAD) simulation to help students engage in engineering design to learn science concepts. Our findings describe three case studies that adopted the same learning design and adapted it to three different populations, settings, and classroom contexts: at the…

Engineering design places unique demands on teachers, as students are coming up with new, unanticipated ideas to problems along often unpredictable trajectories. These demands motivate a responsive approach to teaching, in which teachers attend their students' thinking and flexibly adapt their instructional plans and objectives. A great deal of…

To effectively incorporate engineering into their instruction, K-12 teachers need sufficient knowledge of the engineering discipline. An important component of teachers' engineering knowledge is their understanding of the nature of engineering: what engineers do, the epistemological underpinnings of engineering, and the relationships between…
