This research integrates context-based learning and modelling. It presents a teaching-learning sequence (TLS) about the dissolution of gases in liquids using carbonated drinks as the context. The impact of the TLS is analysed in a longitudinal short-term study involving two groups of learners aged 13-14 years old (n=53). The results led us to…

Einstein's derivation of special relativity theory (SRT), based on hypothetical reasoning and thought experiments, is regarded as a prime example of physics theory development. In secondary education, the introduction of SRT could provide a great opportunity for students to engage in physics theorizing, but this opportunity is largely being missed…

This paper reports on findings from an analysis of trait-formation tasks in the genetic sections of high school biology textbooks. Drawing on studies exploring a range of problems in students' explanations of trait formation, we investigated trait-formation tasks and analysed their potential for knowledge integration and multi-level mechanistic…

Chemical escape rooms (ChEsRms) are educational games in which students use their brain, chemical knowledge, intuition, and a bit of luck to solve a mystery. At the Weizmann Institute, we have developed ChEsRms that are implemented by teachers in their classes. Since the COVID-19 pandemic stopped all the educational activities that took place in…

This technology report presents the main features of a free digital educational tool which aims to introduce middle school level students to the comprehension of the particulate nature of matter in the three states (i.e., solid, liquid, and gas) and during phase transitions. This digital tool is available and is freely accessible online. Its…

Transforming the chemistry curriculum to an interdisciplinary perspective is essential for preparing students to meet interdisciplinary career demands and to brace themselves for the challenges of complex environmental and health issues. The study introduces four interdisciplinary electrochemistry STEM-lab activities as an alternative to the…

In the digital age in which we live, one of the primary goals of education is to nurture individuals who are capable of thinking creatively, solving problems, and being innovative and productive. Computational thinking is an analytical process that requires defining problems and at the same time solving these problems by proceeding in creative…

Hydrogel is an interesting topic in polymer chemistry, which is closely related to daily life and advanced technology. In this paper, we report an activity to deliver hydrogel chemistry into middle school classrooms by undergraduates as a bridge between professors and students. During the activity, undergraduates act as a bridge to receive…

Embedding science learning in real-world issues is a research-based way to generate student enthusiasm, interest, and motivation for science. The authors advocate teaching secondary science in the context of "socio-scientific issues" (SSI). SSI are authentic societal challenges with connections to science, such as climate change,…

Planetariums have been used for a long time in astronomy education. Due to some disadvantages of permanent planetariums, it is seen that portable planetariums have become popular in recent years. Portable planetariums, due to their easy set up in anywhere, offer opportunities for those students studying in the regions where there are not…

There has been a growing awareness that graphing is an essential part of the science curriculum. While much research has focused on student conceptions and abilities regarding graphical representations, only few studies have investigated what teachers think about them and how they use graphs in science class. The purpose of this study is to…

Considering students' increasing lack of interest and motivation for science subjects, it becomes almost imperative to introduce different methodology approaches in classrooms. Besides, decontextualized science teaching, where hands on activities are not sufficiently taken into account, can make the students attitude toward science-learning even…

Teaching modern physics in high school is of increasingly importance as it can offer students a more realistic and updated vision of the world, and can provide an opportunity to understand the most recent scientific discoveries. In this context, general relativity (GR) occupies a prominent place, since it is related to astonishing scientific…

This sixth-form chemistry activity describes how students can use acid-base titrimetry to investigate how adding salt to the aqueous phase may change the value of the partition coefficient of an organic acid between water and 2-methylpropan-1-ol. While the presence of lithium chloride and sodium chloride increases the value of the partition…

Knowing the volume of evolved gases is helpful to select an optimal leavening agent for a particular application. The comparison of leavening agents, their reactions through the baking process in the modern and attractive way, is presented here. A gas pressure sensor probe was used to monitor the pressure change due to the carbon dioxide produced…
