It is a controversial issue that magnetism is an interesting topic for children but also the concept is too abstract for the preschoolers. In this study, an action research is conducted that examines whether the designed intervention program based on STEM can be beneficial for 5-6 years old children to learn more about the specific features of the…

Hands-on projects have been widely used as alternative approaches for teaching and learning of science with direct practical experience on doing to promote students' development of 21st-century skills. Here, we present an implementation of hands-on projects into teaching and learning of magnetic field topic that corresponds with indicators and…

Concept inventories (CIs) are commonly used in pre-post instruction to study student conceptual change. For consistency in assessment interpretation, a CI's assessment construct is desired to maintain invariance across different test times. In this study, the longitudinal measurement invariance (LMI) analysis under the confirmatory factor analysis…

This paper describes an undergraduate laboratory experiment where students study the heating behavior of magnetic nanoparticles in the presence of alternating magnetic fields. Average score on the post-test was 45±12% for students who completed the lab online, versus 43±11% for those doing the activity hands-on. Post-test scores were significantly…

In electromagnetism, to determine the direction of the electromagnetic force and magnetic field, the right-hand rule (RHR) is used. Previous researches show that students have difficulty in applying the RHR. This research is aimed to find out the factors which make it difficult for the students to apply the RHR. To achieve this, qualitative case…

Incorporating modeling activities into classroom instruction requires flexibility with pedagogical content knowledge and the ability to understand and interpret students' thinking, skills that teachers often develop through experience. One way to support preservice mathematics teachers' (PSMTs) proficiency with mathematical modeling is by…

Despite Indiana's school choice landscape -- including private school vouchers, tax-credit scholarships, inter-district and intra-district enrollment, magnet schools, and charter schools -- not all Indiana communities have reasonable access to options outside of their traditional public schools. This research explores what lack-of-reasonable…

Since the Every Student Succeeds Act became law, states have taken advantage of opportunities to engage the arts more broadly in education policy -- from including the arts in STEM education to using the arts as a strategy to meet the needs of underserved youth. At the same time, many states' policy agendas address school choice, with ongoing…

Article describes basic principles of seismic, electric prospection and electrochemical data complexation, received on the same research objects. The goal of our exploration works is complex exploration of hydrocarbon deposits on arctic shelf. Complex is based on ion-selective electrodes for detection of heavy metal complex anomalies in sea…

I describe an easy-to-build instrument for illustrating the Lorentz force and measuring magnetic fields in introductory physics labs.

The concept of reactance in AC electrical circuits is often non-intuitive and difficult for students to grasp. In order to address this lack of conceptual understanding, classroom exercises compare the predicted resistance of a power tool, based on electrical specifications, to measured resistance. Once students discover that measured resistance…

In this qualitative case study, we draw from a larger, federally funded, multiyear study focused on preparing teachers to work with English language learners, which includes an increasing population of refugee background students. We report on the experiences and perspectives of two experienced upper elementary teachers teaching in a magnet school…

As part of the program evaluation under the newly revised "Texas State Plan for the Education of Gifted/Talented Students" (Texas Education Agency, 2019), the Department of Research and Accountability conducted surveys of students, teachers, and parents to establish a baseline about perceptions of the G/T Program and collect formative…

Promoting facility with content knowledge is one of the most important objectives of science teaching. Conventionally, the focus for this objective is placed on the substantive side of content knowledge (e.g. science concepts/laws), whereas its epistemic or ontological aspects (e.g. why do we construct concepts?) rarely receive explicit attention.…

The purpose of this manual is to support school districts and schools in developing diverse and equitable magnet programs. It is intended to help stakeholders during the planning phases of developing new magnet schools or during the revision or expansion of existing magnet schools. The manual focuses on: (1) Why districts should consider…
