This study investigates the effect of using the history of science in teaching geometrical optics on the motivation and conceptual understanding of first year university students. For this purpose, 54 students were randomly selected, then divided into two groups: the experimental group was taught by using history of science before traditional…

This study aims to assess whether the handling of concrete ball-and-stick molecular models promotes translation between diagrammatic representations and a concrete model (or vice versa) and the coordination of the different types of structural representations of a given molecular structure. Forty-one Algerian undergraduate students were requested…

This paper aimed to empirically test whether implementing the blended teaching approach in ESP courses positively affects students' achievement and their attitudes towards it. To this end, explanatory type and quasi-experimental design research were carried out with two groups of students (N = 60) enrolled in the computer science department at…

Spurred on by new discoveries and rapid technological advances, the capacity for life science research is expanding across the globe-and with it comes concerns about the unintended impacts of research on the physical and biological environment, human well-being, or the deliberate misuse of knowledge, tools, and techniques to cause harm. This…

This work aims to assess the difficulties encountered by students of the Ecole Normale Superieure of Kouba (Algeria) intending to teach physical science in the integration of the hybridization of atomic orbitals. It is a concept that they should use in describing the formation of molecular orbitals ([sigma] and [pi]) in organic chemistry and gaps…

The COVID-19 Pandemic impacted world society in many ways. The virus rode our interconnected transit systems and exploited a globally connected world where a person can traverse the planet within a day; far shorter a time than the incubation period. The virus challenged our assumptions on communicability of disease and transmission vectors. It…
