As the world races to combat a pandemic, slow climate change, and solve many other public health challenges, it is clear that developing young people's scientific knowledge should be an urgent priority in schools. The goal of the Next Generation Science Standards (NGSS) is to foster scholars and citizens who can think critically and creatively to…

The "Playground Physics" program combines informal, play-based, embodied learning experiences to support middle school students' engagement with and motivation to learn about complex and abstract physics concepts. This experimental design study examines the impact of "Playground Physics" on students' science motivation,…

In this study, we evaluate the impact of rehearsing teaching skills in a mixed-reality classroom simulator on graduate teaching assistants' (GTAs) instructional practices as well as undergraduate student learning outcomes. The simulator training is intended to provide GTAs opportunities to deliberately practice essential pedagogical skills that…

Representational competence is essential for the acquisition of conceptual understanding in physics. It enables the interpretation of diagrams, graphs, and mathematical equations, and relating these to one another as well as to observations and experimental outcomes. In this study, we present the initial validation of a newly developed…

The immense benefits of e-learning cannot be overemphasized. In addition to solving the time and space constraints posed by the traditional/conventional learning methods, it can be more adaptive and interactive to achieve optimum learning output/results. As a consequence of students' varying backgrounds and different learning abilities, the…

This work describes the use of a single chemical reaction to teach and connect a number of standard general chemistry course topics while also introducing students to polymer concepts. Through the study of the reaction that converts spiropyran into merocyanine, we are able to present and connect molecular orbital theory, quantum mechanics,…

Novel carbon nanomaterials such as reduced graphene oxide (rGO) and graphene oxide (GO) can be easily incorporated into the undergraduate curriculum to discuss basic chemistry and nanotechnology concepts. This paper describes a laboratory experiment designed to study the differences between GO and rGO regarding their physicochemical properties…

In this research, the development of the Optics Interest and Experience Scale (OIES) was discussed in the first stage, and the gender differences of prospective teachers in their interest and experience were explored with OIES in the second stage. The data were collected from 228 prospective teachers from eleven universities in Turkey. For content…

A common method that scientists use to validate a theory is to utilize known principles and laws to produce results on specific settings, which can be assessed using the appropriate experimental methods and apparatuses. Smartphones have various sensors built-in and could be used for measuring and logging data in physics experiments. In this work,…

Along-standing energy lab involves dropping bouncy balls and measuring their rebound heights on successive bounces. The lab demonstrates a situation in which the mechanical energy of a system is not conserved. Although students enjoyed the lab, the author wanted to deepen their thinking about energy, including the connections to motion, with a new…

Energy and matter are fundamental, yet challenging concepts in middle school chemistry due to their abstract, unobservable nature. Although it is important for science teachers to elicit a range of students' ideas to design and revise their instruction, capturing such varied ideas using traditional assessments consisting of multiple-choice items…

We propose a process of contextualization based on seven empirically derived contextualization principles, aiming to provide opportunities for Indigenous Mexican adolescents to learn science in a way that supports them in fulfilling their right to an education aligned with their own culture and values. The contextualization principles we…

Experiments are described that involve undergraduates learning concepts of nanoscience and chemistry. Students prepare nanopatterns of organosilane films using protocols of particle lithography. A few basic techniques are needed to prepare samples, such as centrifuging, mixing, heating, and drying. Students obtain hands-on skills with nanoscale…

As the need for alternative energy becomes increasingly important, energy research and related industries are rapidly expanding. This lab incorporates current energy-storage research into a second-year lab that instills real-world, industry-relevant knowledge and skills while teaching and reinforcing physical-chemistry concepts. A manganese oxide…

Comparative education is important for recognising the education systems of different countries for bringing new practices into the education system and for ensuring educational equality among different societies. This study discusses the education systems of Turkey, Singapore and Kazakhstan. The science programmes of the three countries are…
