In this paper we describe an activity for engaging students in crafting definitions. We explore the strengths of this particular activity as well as the broader implications of engaging students in crafting definitions more generally.

If a body is in equilibrium under the action of three non-parallel coplanar forces, the forces must be concurrent, that is, must meet at a single point. Specific examples are provided here to illustrate the validity of this statement by the use of free-body diagrams as well as during the discussion of equilibrium and moments. These cases are…

Two bodies initially at different temperatures gathered into an isolated container exchange heat and reach an equilibrium state with a common final temperature. During the process, the system is out of equilibrium and its intermediate temperature is not well defined. By conceiving a quasi-static process with infinitesimal steps from the initial to…

In our everyday life, it seems that magnetic phenomena are restricted to ferromagnetic materials or electromagnetism caused by electric currents. From a physics point of view, we know that this everyday experience is contrary to the nature of magnetic phenomena. If one regards the magnetic properties of the elements of the periodic table in their…

One of the most popular demonstration experiments pertaining to Bernoulli's principle is the production of a water spray by using a vertical plastic straw immersed in a glass of water and a horizontal straw to blow air towards the top edge of the vertical one. A more general version of this phenomenon, appearing also in school physics problems, is…

In this chapter we report and discuss inquiry-based science teaching/learning and more specifically dialogic inquiry, as a basis for a professional development programme for teachers. The pilot programme aimed at (1) considering teachers' experience, (2) letting teachers develop their current lessons and (3) prompting teachers' reflections on…

The purpose of this study was to explore translanguaging space as a transformative third space, where alternative and competing discourses are celebrated and where science learning and the development of science's discourse and epistemic practices expand across overlapping boundaries (e.g., home, school, and community). The study focused on Syrian…

DBL is a novel pedagogical approach intended to improve students' conditional knowledge and problem-solving skills by exposing them to a sequence of branching learning decisions. The DBL software provided students with ample opportunities to engage in the expert decision-making processes involved in complex problem-solving and to receive…

This qualitative case study delved into students' understanding and positioning while they participated in solving an authentic, conceptually-based problem in a high-school chemistry class. Verbal and nonverbal cues, particularly gestures, offered broader awareness of students' engagement in sensemaking during the learning experience. The…

Background: Science skills play a crucial role in fostering economic development and technological innovation, making the enhancement of science education a global priority. Despite the recognized importance of teacher practices in enhancing equitable and effective learning, much of the research on their impact on student outcomes has been…

Contemporary science education themes are marked by the inevitable uncertainty of consequences emerging from human actions. They encompass disasters, pandemics and other events that have been marking our present times. Understanding new risks as the ones resulting from human action, even when proposing a solution for an issue, is one of the…

Understanding particle motion in force fields (PMFF), which encompasses the nature of forces and the relationship between force and motion, is fundamental to mastering mechanics and electromagnetism. Effectively solving PMFF-related problems requires advanced reasoning skills and the ability to apply knowledge across diverse contexts. Despite…

This article describes how a class dedicated to supporting language needs in concurrent science courses developed complex grammatical literacy with an emphasis on a functional understanding of language for technicality, precision, and persuasion. The success of the curriculum was predicated on three factors: the grammatical content selection and…

The perspectives of science teachers and students is of paramount focus of this study regarding the use of ChatGPT in the science classroom as a supplementary tool within Mandaluyong City, Philippines for the school year 2023-2024. 899 junior high school students and 26 science teachers were surveyed using the quantitative research design,…

Biology education worldwide at different levels involves learning to identify plants and animals in nature. The aim of this study was to investigate the effectiveness of a teaching and learning method for bird identification that combines active outdoor fieldwork with active online learning, testing the validity of our instrument. Altogether, 798…
