The U.S. Education system is founded on a Eurocentric focus of curriculum, and students of color are not achieving as high as white students on the National Assessment for Education Progress in science. This research aims to repay the education debt owed to students of color by decolonizing science curriculum through the implementation of lessons…

Lately, new materialism has been proposed as a theoretical framework to better understand material-dialogic relationships in learning, and concurrently network analysis has emerged as a method in science education research. This paper explores how to include materiality in network analysis and reports the development of a method to construct…

We examine how a unique professional learning experience for teachers, which consists of an opportunity to (a) co-design a new instructional model intended to give students opportunities to participate in scientific argumentation, (b) develop instructional materials based on the new model, and then (c) use the materials inside their classrooms, is…

As part of a multiyear research project investigating the affordances of online citizen science (OCS) projects for enhancing school students' learning in relation to science and digital technology, teacher-researchers have designed and implemented classroom interventions incorporating one or more OCS projects. The project is situated in New…

A pilot study, funded by the Gatsby Charitable Foundation, supported 10 secondary schools across England to plan and deliver open-ended investigative practical work within science curriculum time. This enabled all students to experience the benefits of investigative work, rather than just those attending extracurricular STEM enrichment activities.…

High school science classrooms across the United States are answering calls to make computation a part of science learning. The problem is that there is little known about the barriers to learning that computation might bring to a science classroom or about how to help students overcome these challenges. This case study explores these challenges…

In this work, an alternative Experimental Didactic Kit for teaching resistors, capacitors and "RC" timing circuits was developed, using the Arduino platform technology, which is composed of a microcontroller and peripherals, due to the easy access to available teaching materials, enabling the reproduction of the prototype in the future…

Teachers' individual beliefs regarding the value of the academic material they teach, the nature of the subject, how they should teach it, as well as their assumptions regarding students, classrooms, instructional materials, the nature of learning, and how students construct knowledge can all have considerable influence over their teaching…

This paper draws attention to basic philosophical perspectives which are of theoretical and methodological interest for science education, general education and curriculum research. It focuses on potential contributions philosophy class can offer if philosophy education opens up for science and for a collaboration of teachers in the context of…

Information and knowledge of science are very necessary and vital inputs for growth and survival in modern times. Science is a body of knowledge that can be rationally interpreted and applied consistently in human endeavors. Science as a form of information is a way to examine a process and a way of thinking in the quest for an understanding of…

Understanding the intellectual demands of an intended curriculum is crucial as it defines the frames for teaching and learning processes and practice during lessons. In this study, upper-secondary school chemistry curricula contents in Czechia, Finland, and Turkey were analysed, and their objectives were compared using the Revised Bloom's Taxonomy…

In high school and elementary college physics labs the measurement of vertical distance is often required. Measuring the distance an object falls or the vertical displacement of springs in a Hooke's law experiment are commonplace. Determining these distances to perhaps a millimeter or two of precision is difficult without an expensive height gauge…

The dynamics of a spring pendulum is an important topic in introductory experimental physics courses at universities and advanced science courses in secondary school education. Different types of pendulum setups with smartphones were proposed to investigate, e.g., the gravitational acceleration, to measure spring constants, or to illustrate and…

When injecting dye into a vortex, one finds that the dye remains captured around the vortex core over minutes, despite the fact that the vortex (and the dyed region) is strongly time-dependent. According to a recent theory, three-dimensional time-dependent vortices should be defined as rotating, material-holding regions of the fluid. Vortices…

The fact that a bungee jumper can reach an acceleration greater than the acceleration of gravity is, also from a physics point of view, intriguing. Taking only gravity into account, it can be explained by applying conservation of energy or by deriving carefully the equation of motion in a Newtonian approach. In this article we show how it can be…
