The nature of students' ideas about the scientific practices used by astronomers when studying objects in our Solar System is of widespread interest to discipline-based astronomy education researchers. A sample of middle-school, high-school, and college students (N = 42) in the U.S. were interviewed about how astronomers were able to learn about…

Audio- and video-recordings are increasingly popular data sources in contemporary qualitative research, making discussions about methodological implications of such recordings timelier than ever. This article goes beyond discussing practical issues and issues of "camera effect" and reactivity to identify three major challenges of using…

Proponents of dynamic testing have advocated its use as a replacement or addition to conventional tests. This research aimed to investigate the effects of using versus not using a pretest on both the outcome on the posttest and the processes used in solving inductive reasoning tasks in dynamic testing using a graduated prompts training.…

This article argues that the role of practical work in science is overemphasised and misunderstood. Science is distinguished by the fact that it is a set of ideas about the material world and not by empirical enquiry. The latter is only one of six styles of reasoning that have been used to develop scientific ideas. The lack of clarity around the…

Beliefs about the certainty of teaching knowledge may influence how preservice teachers engage with and learn from knowledge sources in teacher education, and their subsequent practice. In light of inconsistencies in prior findings that mainly employ epistemic questionnaires, we extended research focusing on a contextual analysis. Sixty-six…

The purpose of this commentary is to explore the intersection of creativity, civic engagement, and literacy instruction that takes into consideration real-world concerns. The authors define and consider recent work on creativity and utilize Westheimer's model of citizenship to frame an example of adolescents engaged in both purposeful literacies…

Helping students learn to think like a physicist is an important goal of many introductory physics courses. One characteristic distinguishing more experienced physicists from novice students is that they make better use of problem solving as a learning opportunity. Experts were found to spend more time than novices in monitoring their work,…

Making and recording scientific observations is a fundamental activity of the scientific community. Scientists use their senses and tools (e.g., magnifying glasses, rulers, colored pencils) to make records of the phenomena (e.g., light energy, ecosystems) they are investigating. These observations often serve as evidence in the scientific…

To further students' understanding about gravity, forces, and motion, multiple types of text were integrated into instruction. As part of a 5E lesson (Bybee et al. 2006), the authors used a selection from Capstone Press's Graphic Science series, "A Crash Course in Forces and Motion with Max Axiom" (Sohn and Barnett 2007) to support…

When working within a meaningful context quite young students are capable of working with sophisticated data. Year 3 students investigate thermal insulation and the transfer of heat in a STEM inquiry, developing skills in measuring temperature by conducting a statistical investigation, and using a stylised graph to interpret their data.

We present a geometrical investigation of the process of creating an infinite sequence of triangles inscribed in a circle, whose areas, perimeters and lengths of radii of the inscribed circles tend to a limit in a monotonous manner. First, using geometrical software, we investigate four theorems that represent interesting geometrical properties,…

Mathematics needs to take on a real-world quality, and students need to be able to identify and connect the value of what they are learning within the classroom to life outside the classroom. Creating a connection between the mathematics learned within a classroom and its value to life in the outside world is critical to effectively engage…

This phenomenological investigation examined the perceptions of Catholic elementary school teachers and their homework practices within a suburban Catholic school in California. The purpose of this study was to understand the lived experiences of Catholic school teachers regarding the standard practice of assigning homework to elementary school…

Since 1995 all Swedish compulsory schools have been required to establish Individual Educational Plans (IEPs) for pupils with special educational needs. According to the Swedish Education Act such a plan should be drawn up if pupils do not achieve the goals in the curriculum or the syllabus. The process of IEPs covers a prior investigation to…

A simple mathematical formulation of Mach's principle is given based on a century of investigation into inertia, and used to check the results of Newton's famous bucket experiment.
