Herein, we explore the impact of using a flipped classroom approach on the achievement of learning outcomes in the International Union of Pure and Applied Chemistry (IUPAC) inorganic nomenclature in fundamental chemistry courses at the university level. In addition, the study sought to evaluate student attitude, motivation, and engagement when…

The research examines the concept of consciousness from a materialistic and idealistic position and clarifies the essence of the concept of moral consciousness. The authors give a brief overview of the problem of forming moral consciousness of schoolchildren. The authors describe the influence of the humanities and natural sciences on the…

This paper illustrates utilising cultural historical activity theory (CHAT) and the methodology of formative intervention as a responsive capacity-building framework for enhancing science teachers' professional development and system-level capacity in multilingual settings. We report findings from the initial Change Laboratory (CL) meetings of an…

In this study, we developed an online problem-based learning (PBL) module for the Impulsive Force subtopic of Physics Form Four and studied its perceived usability among Physics trainee teachers. The research design of this study is developmental research and a quantitative study using a survey approach. The module was developed according to five…

Despite the challenges posed by expository instruction materials, including unfamiliar text structure and abstracted and isolated representation of the contents, they constitute a primary means of studying scientific concepts in higher education. Conversely, utilizing narratives to present the to-be-learned content was conjectured to mitigate some…

The use of multiple-choice (MC) instruments to assess pedagogical content knowledge (PCK) has advantages in terms of test economy and objectivity, but it also poses challenges, for example, in terms of adequately capturing the intended construct. To help address these challenges, we developed and evaluated a new instrument to assess science…

Renal clearance encompasses a somewhat abstract concept, which makes it a hard-to-visualize phenomenon. It is a confusing topic for students and a difficult task for the instructor to teach. In order to improve or facilitate the teaching-learning process of renal clearance, an alternative strategy is presented here. To properly characterize the…

Previous generations of physics students learned how common machines work, as evidenced by their textbook illustrations. Such understanding of machines that daily life depends on seems to be evaporating. In response, for two decades I have conducted an introductory physics "engine cadaver lab." It offers opportunities for hands-on…

There are many phenomena, interesting, simple experiments and effects, that await their in-depth explanation from the point of view of physics. Some of them have been well known for a long time but their numbers are increasing, especially with the introduction of new technology in everyday life. In this paper we consider a simple experiment that…

There is now a significant research literature devoted to reconceptualizing scientific activities, such as modeling, explanation, and argumentation, to realize a vision of science-as-practice in classrooms. As yet, however, not all scientific practices have received equal attention. "Planning and Carrying out Investigations" is one of…

Teaching through discrepant event activities increases student interest in science. In this article, I will introduce a well-known 19th century demonstration, the Tissandier experiment, to stimulate curiosity among students learning the concept of inertia. In this demonstration, a hard object (e.g. a wooden rod) placed on fragile supports is…

Due to immense cost reduction and routine commercial availability, 3D printing has become the cutting-edge technology with enormous potential--also for educational and applied chemistry. It opens the opportunity to print custom-made reactors, such as (micro) flow reactors. In addition, 3D-printing technology can simplify chemical reactions, such…

We have demonstrated both interference and diffraction of a pseudo-double slit using two glass plates with a width and a length of about 5 cm and a thickness of about 5 mm. The plates are attached at the upper and lower ends with Scotch tape of about 0.1 to 0.3 mm between the plates. By adjusting the angle between the two plates, we are able to…

The mathematical method of linear equations involving the coefficients of the equation of a chemical reaction can be used to balance the equation of nearly every chemical reaction. For its application, only the rules of simple algebra need be known. Hence, the method could even be used by students of an elementary chemistry course.

An experiment using the volumetric flux of a water stream was used to find the initial velocity of the water as it performs parabolic motion. The trajectories were measured with different initial velocities, comparing the maximum height and range values with the theoretical calculations. The closeness of the measured values to the calculations…
