According to Martin Buber's philosophy of dialogue, our being-in-the-world is to be conceived of as an existential dialogue. Elsewhere, I have conceptualized the teacher-student-relation accordingly (see Jons 2008), as a matter of calling and responding. The conceptualization rests on a secularised notion of vocation, paving way for…

The paper is a philosophical analysis of experimentation. The philosophical framework of the analysis is the interrogative model of inquiry developed by Hintikka. The basis of the model is explicit and well-formed logic of questions and answers. The framework allows us to formulate a flexible logic of experimentation. In particular, the formulated…

A Cartesian diver can be used to measure the surface tension of a liquid to a certain extent. The surface tension measurement is related to the two critical pressures at which the diver is about to sink and about to emerge. After sinking because of increasing pressure, the diver is repulsed to the centre of the vessel. After the pressure is…

This article is about moments when teachers experience hate speech in education and need to act. Based on John Dewey's work on moral philosophy and examples from teaching practice, I would like to contribute to the discussion about moral education by emphasizing the following: (1) the importance of experience, (2) the problem with prescribed…

Representations are often used in instruction to highlight key mathematical ideas and support student learning. Despite their centrality in scaffolding teaching and learning, most of our understanding about the tasks involved with using representations in instruction and the knowledge requirements imposed on teachers when using these aids is…

Educators are consciously or unconsciously guided by pedagogy and make critical decisions about praxis--content, strategy, structure--based on their pedagogical beliefs. The intentional use of pedagogy is often advanced as a key to being an effective educator. A wealth of literature is directed toward helping White educators develop a race…

Anti-racist pedagogy typically focuses on helping learners identify and counter racist ideas and actions they detect in themselves and others. Sympathetically and skillfully, the leader of this activity is charged with helping people detect subtle racism as evident in racial micro-aggressions and aversive racism. This pedagogic process is crucial…

A few years ago we began to revamp our introductory physics course for life science students. We knew that this cohort would be less prepared and less adventurous mathematically than engineering, physical science, or mathematics majors. Moreover, from our own experience and the mathematics education literature, we knew that trigonometry would be…

The primary objectives of this article are: (1) to conceptualize teacher dispositions related to teaching spatial thinking in geography classrooms; and (2) to propose an exemplar assessment that can be used to prepare teachers who are disposed toward teaching spatial thinking through geography. A detailed description of the construction procedures…

Vortex cannons have been used by physics teachers for years, mostly to teach the continuity principle. In its simplest form, a vortex cannon is an empty coffee can with a hole cut in the bottom and the lid replaced. More elaborate models can be purchased through various scientific suppliers under names such as "Air Cannon" and…

This paper is the second in the series of LED-dedicated papers that have a goal to systematically investigate the use of LEDs in a general physics course. The first paper, published in the February 2014 issue, provided an overview of the course units where LEDs can be used and suggested three different ways of utilizing LEDs in an introductory…

One of the basic ideas when studying science is that matter is composed of particles (atoms or molecules) and these are in a constant state of agitation. In the solid or liquid state the molecules are attracted to each other, while in the gaseous state they have sufficient energy to overcome the forces of cohesion and can move away from one…

Across continents, creativity is a priority for education and is central to the discourse on 21st century learning. In this article, we explore how a greater focus on "everyday creativity" in schools changes the dynamics of teaching and learning. We look briefly at the main concepts in the literature on creativity in education. We then…

Particularly in the second half of the 20th century, historical approaches became relevant in science education. This development can at least in part be explained with the growing awareness of the importance to address Nature of Science aspects in science education. In comparison to the international publications, some particularities can be…

A museum belonging to a school district demonstrates how teachers integrate museum resources into classroom curricula. A former teacher reflects on her experience with the Karshner Memorial Museum in the Puyallup School District (WA), and explains how the museum's exhibitions and artifacts are curriculum resources, specifically tied to grade level…
