Enhancing the problem-solving skills of learners belonging to socio-economically disadvantaged groups is a great concern in general and particularly in the Indian context. Problem-solving skills are the most important skills of the 21st century for all learners to acquire necessary competencies. The main purpose of this work is to investigate the…

It is widely recognized that we need to prepare students to think with data. This study investigates student interactions with digital data graphs and seeks to identify what might prompt them to shift toward using their graphs as thinking tools in the authentic activity of doing science. Drawing from video screencast data of three small groups…

The demand for improving student interest in science has increased efforts toward teaching Einstein's theory of general relativity in schools. Research has already shown that teaching Einsteinian gravity at the secondary level is feasible, however, appropriate resources must be readily available for science teachers to make Einsteinian gravity…

The natural sciences, by their very nature, are based on the exploration of the physical world, and digital mobile devices are considered appropriate to support this exploration (Suárez et al., 2018) since they offer the tools that make this investigation more accessible but also ubiquitous (Crompton et al., 2017). Inquiry-based learning is a…

Although nearly everyone is familiar with colors from an early age and the fundamentals of color mixing are taught at various abstraction levels throughout kindergarten to high school, we repeatedly observe that our student teachers in physics have problems in explaining the subject. Therefore, we propose an experimental setup that focuses on the…

Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

Dark matter comprises most of the matter in the universe, yet physicists are unsure of its nature. A significant effort is devoted in contemporary research to attempts to understand dark matter, making it a both captivating and relevant area of astrophysics to discuss in a classroom setting. What is more, the physics behind these experiments is…

We report the findings of an empirical study that investigated whether the source of data--firsthand or secondhand data gained from lab work experiments--has an influence on students' learning outcomes. Results indicate that students' choice of a correct or incorrect hypothesis for a pendulum lab experiment on the influence of the mass of the bob…

When the thermal expansion of water is discussed in school or university lessons, functional relationships are often inferred without considering measurement uncertainties. Moreover, in some learning materials, the goal of experimentation and the experimental setup do not match. This creates the wrong picture of scientific practice. In this…

Practical work is a distinctive feature of school science and has close associations with scientific experiment and scientific methods as well. In this study, the nature of practical work was examined in the view of the diversity of scientific methods. Based on an analytical framework derived from Brandon's matrix consisting of four categories of…

While the use of experiments is important for developing students' scientific knowledge and skills, challenges may arise when teachers and students are conducting experiments in class, such as non-reusable experimental resources, safety issues and difficulties simulating some specific effects. Augmented reality (AR) technology affords an…

Our motivation for this article is for students to realize that opportunities for discovery are all around them. Discoveries that can still puzzle present day researchers. Here we explore an observation by a middle school student concerning the production of what appears to be water-like "ripples" produced in aluminum foil when placed…

Affective and cognitive outcomes of science teaching in schools may be enhanced by science outreach labs (SOLs). Particularly interesting is whether and how to connect SOL visits to in-school science learning. Recent studies--among others, in this journal--have confirmed SOLs' positive affective effects. However, research remains inconclusive…

Proper understanding of and learning from physics phenomena and experiments requires--among other competencies--flexible and coherent use of multiple representations (MRs). These can include everything from the "enactive" or "operational" manipulation of the experimental devices and materials to the most abstract level of a…

Cosmic expansion is an important concept in astronomy. For ease of understanding, astronomers generally draw an analogy between cosmic expansion and the expansion of a spherical surface in 3D space. This study theoretically and experimentally investigates the laws governing the motion of particles on the surface of a balloon during expansion.…
