Unstructured out-of-school time (OST) science activities, such as reading a science book, watching a science television show, or researching on the internet about science, constitute a self-sustaining way for adolescents to engage in science, technology, engineering, and mathematics (STEM). Although it is suggested that long-term engagement in…

In this paper we present a simple dimensional analysis exercise that allows us to derive the equation for the Hawking temperature of a black hole. The exercise is intended for high school students, and it is developed from a chapter of Stephen Hawking's bestseller "A Brief History of Time."

Thought experiments are personal and tacit processes of experimentation that scientists perform within their own imagery in formulating new theories or refuting existing theories. However, by viewing learning as a social process, this study aims to show that thought experiments can also be constructed collaboratively and to present a detailed…

Students tend to think of their science courses as isolated and unrelated to each other, making it difficult for them to see connections across disciplines. In addition, many existing science assessments target rote memorization and algorithmic problem-solving skills. Here, we describe the development, implementation, and evaluation of an activity…

Lampworking is a valuable skill for students in Chemistry and others in science, technology, engineering, and math (STEM) related fields. The activity described here provides instructors the resources to both learn and teach the fundamentals of lampworking. Soft glass, which can be shaped and fused with a Bunsen burner, is used to improve the…

This research is a descriptive study that aimed to investigate STEM competencies of science and mathematics preservice teachers. For this purpose, a group of science and mathematics preservice teachers were asked to design and conduct parachutes covering the topics of movement (free fall, air resistance and lift force) in the course of physics I.…

The classic brachistrochrone problem is standard material in intermediate mechanics. Many variations exist including some accessible to introductory students. While a quantitative solution isn't feasible in introductory classes, qualitative discussions can be very beneficial since kinematics, Newton's laws, energy conservation, and motion along…

Nanochemistry is an important aspect of modern chemical science. Though few educational institutions teach nanochemistry as a formal course, general exposure of students to nanoscience is yet important. Thus, we present a nanochemical activity that could be used as part of many chemistry courses or laboratories based on ChemToy2. This activity is…

Anatomical sciences curricula have been under constant reform over the years, with many countries having to reduce course hours while trying to preserve laboratory time. In Mexico, schools have historically been autonomous and unregulated, and data regarding structure and methods are still lacking. A national survey was sent by the Mexican Society…

The High Road/Low Road race is often used as a qualitative prediction activity. A marble is released simultaneously on two elevated tracks that differ only in the middle section where the Low Road dips before finishing at the same height as the High Road. Typically a minority of students correctly predict that the Low Road will finish first. In…

Interactive digital technologies are playing an increasingly important part in education for enhancing collaborative learning processes and improving engagement. Social annotation (SA) tools and collaborative platforms are an innovative way to involve students to give and take feedback, annotate, and brainstorm on complex topics in science,…

This study aimed to investigate how argument-driven inquiry (ADI) activities impact pre-service teachers' views of the nature of scientific inquiry (NOSI), with a specific focus on climate change. To this end, an ADI approach was used to teach climate change, where the aspects of NOSI were explicitly taught. A sample of 24 pre-service teachers…

LASAR (Learning about Science and Religion) has been exploring different opportunities to engage children with practical science enquiry to develop children's understanding of the nature of science and how they suppose science connects to 'big questions'. After-school club opportunities and classroom opportunities are presented.

This communication describes an activity where upper-level chemistry students explore the determinability of rate constant values without concentration dependences (k[subscript true]) related to a solvent-ligand exchange in a transition metal carbonyl complex. By performing a series of multivariable linear regression (MVLR) analyses of…

Trust in science is indispensable and very important for the development of global health, and can certainly be gained by developing the scientific literacy of the whole population. The article presents various definitions of scientific literacy and seeks its connections to science education. It further explores the progress in developing…
