Teachers can learn a lot from John Dewey's approach to teaching science. The author contends that his thoughts are still relevant and applicable to today's classrooms.

This is a fundamental and pedagogical work in quantum physics/chemistry, where we try to illustrate the Mulliken's question, "What are the electrons really doing in molecules?". And we also briefly review the development of the most popular numerical approaches in computational chemistry. We examine in a novel approach, how we can…

From ancient times, the different features of planets and moons have created a huge interest. Aristarchus was one of the first to study the relative relations among Earth, Moon, and Sun. This interest has remained until today, and therefore it is always relevant to make this knowledge more appealing to the younger generations. Nowadays, smartphone…

People often have difficulty in understanding processes of biological change, and they typically reject drastic life cycle changes such as metamorphosis, except for animals with which they are familiar. Even after a lesson about metamorphosis, people often do not generalize to animals not seen during the lesson. This might be partially due to the…

Student teachers struggle to identify themselves as teachers in their field placement during their student teaching year, and some of the difficulty can be attributed to the change they encounter when they must communicate scientific ideas to students in a language that differs from how they recently learned science at the university level. Using…

Experiment is understood as a core activity in science education as well as science in general. Despite many efforts to improve science education in the laboratory, a cookbook style of verification experiments often dominate school science. In this study, we conducted an open laboratory activity that provided students with an opportunity to think…

Three-dimensional symmetry plays a crucial role in crystallography education. The educational process can be facilitated by introducing the analysis of friezes and plane patterns such as parquets before presenting more sophisticated crystal structures. Analysis of the symmetry of parquets can serve as an opportunity to follow the full routine of…

Each year, an increasing number of science teachers integrate modeling into their instructional repertoires, and in the process, they see how this disciplinary practice helps students reason and revise their thinking about complex events in the natural world. The NGSS Science and Engineering Practice of developing and using models is intended to…

A phone emitting sound of a fixed frequency is sliding on an inclined plane and approaching a second phone kept at the bottom of the plane. The detected frequency versus time data by the second phone are used to calculate the acceleration of the sliding phone. The primary objective of this paper is to calculate the sliding friction between the…

As students learn physics, they are often required to reason about the behavior of macroscopic and microscopic phenomena, and to synthesize prior knowledge from several different areas of physics to construct understanding of new ideas. This can be a tremendously difficult cognitive task for novice students, especially when the unfamiliar…

Collisions are a key topic in physics and engineering education. An experiment with multiple body one-dimensional collisions is presented, aiming to measure relevant physical quantities by tracking the motion of the system of particles during the collision. Relations between different physical quantities can be explored in the experiment, such as…

It might sound to some like an impossible target to give children 22 hours of scientific enquiry by Christmas, but the current COVID-19 pandemic has already demonstrated its capacity to make the impossible happen and to upturn so many of the assumptions that have shaped the way people teach and learn. Children can reach 22 hours of enquiry if…

This activity allows students to visualize how to obtain different stoichiometries with various techniques in a single experiment. The involvement of three phases adds to the student's interest. Instructional materials are provided to facilitate the experimental procedures, interpretation of results, and error analysis. The reaction of Li from a…

This study uses a one-group pre-test and post-test design to describe the mental models of geologic time held by a group of Spanish pre-service primary teachers, before and after an instructional intervention that introduced the work with different timescales. The questionnaire was given before instruction and five weeks after it. It consists of a…

This paper details the creation of a human gross anatomy laboratory from a defunct chemistry laboratory at West Liberty University, a small primarily undergraduate institution in West Virginia. The article highlights important considerations with regard to the development of a human gross anatomy laboratory including access to human gifts;…
