Background: In science education asynchronous online interactions have increased dramatically during the recent pandemic and some of these practices will stay. One of the characteristics in asynchronous exchanges is the spacing and sequencing of online interaction. It means that dialogue partners do not necessarily receive immediate feedback as is…

Educational kits can improve the teaching of experimental sciences, providing an interesting strategy to be explored at home, especially during the COVID-19 pandemic. In this sense, chemistry kits based on a microscale design were developed encompassing safety, portability, efficacy, and low cost. They were successfully applied in regular classes…

Studies have shown that inadequate definitions of scientific concepts could complicate the learning of science and could prevent students from understanding the definitions of scientific concepts. The article provides a framework for defining scientific concepts in primary, secondary, and university education by proposing teachers draw attention…

In this paper, the education system in Bosnia and Herzegovina is presented in the light of current state-level legislation, with an emphasis on chemistry education at the primary, secondary and tertiary level. The consequences of the last war in our country still persist and are visible in many aspects of everyday life, including the education…

Teaching natural sciences can be challenging, especially with unmotivated or disinterested students. The challenge increases when the term "Didactics" appears in the subjects under study, for example, with Didactics of Natural Sciences. The present work details the design and execution process of an escape room experience used as a…

A self-avoiding walk (SAW) is a sequence of moves on a grid that does not visit the same point more than once. SAWs are used to study how networks form, including social networks, biological networks and computer networks, and have provided inspiration to scientists, artists and designers. Here we describe a collaborative project which aims to…

To promote the integration of aesthetic education into chemistry education, this study designed activities to photograph precipitation reaction experiments with a smartphone, thereby combining experimental inquiry with artistic creation across disciplines. These activities were divided into (i) perceiving, (ii) appreciating, (iii) exploring, and…

The study aims to present the development of education in North Macedonia from the country's independence to the present day, as documented in several national reports and other official documents. The focus is on development and changes in chemistry education throughout the years of primary, secondary and higher education. Particular attention is…

This study is to determine the effect of using a fun book in a science course to enhance academic achievement and retention and to investigate student's views on the use of the fun book. Another aim of the study is to set an example for process evaluation in using fun lessons for higher education students. Participants used the fun book for…

Comprehension of the 3D structure of objects usually represented in 2D is a critical part of understanding molecular geometries. The frequency with which students actually get hands-on with 3D molecular structures is often limited to a singular laboratory session. We sought to develop a set of molecular shapes that were inexpensive enough not only…

We report a series of three experiments that introduce students at different stages of their academic preparation to the medical applications of hydrogels for controlled drug delivery and wound healing. The laboratory activity bridges the fundamental concepts of chemistry (acids and bases, equilibria, solvation, and reversible esterification) with…

Over the past 25 years, the Davidson College Physics Department has developed small computer programs called Physlets. These programs were written in Java and distributed as Java applets embedded in HTML pages. Physics teachers from around the world used Physlets to author interactive computer-based curricular materials for the teaching of…

These proceedings contain papers of the 4th International Baltic Symposium on Science and Technology Education (BalticSTE2021) held in Šiauliai, Lithuania, June 21-22, 2021. This symposium was organized by the Scientific Methodical Center "Scientia Educologica" in cooperation with Scientia Socialis, Ltd. Lithuania. The proceedings are…

The purpose of this study was to describe the effect of multiple knowledge representations of physical and chemical changes on the development of primary pre-service teachers' cognitive structures. The study took place in an introductory general chemistry laboratory course in a four-year teacher education program. Multiple knowledge…

The ability to express scientific concepts in mathematical terms and integrate scientific and mathematical reasoning about a phenomenon is a foundational cognitive process involved in scientific thinking. This process called "blended math-science sensemaking" (MSS) is a desired skill for all science, technology, engineering, and math…
