Thinking skills as a cognitive process are life skills needed by students in academic activities. This study aims to implement the Project-Based Learning integrated with Science, Technology, Engineering and Mathematics (...

Chemical literacy as a scientist’s life skill needs to be promoted through teaching and learning activities. This study aims to implement socio-scientific issue (SSI)-based learning to improve chemical literacy skills ...

Achievement of analytical chemistry competency needs to be optimized through the application of active learning models. This research aims to design an active learning model oriented towards green chemistry with virtual ...

Grounded in the need to modernize science education and promote learner-centred approaches, this study examined the effectiveness of integrating context-based 7E instructional strategies, rooted in constructivist learnin...

Dust explosions represent a constant danger in the processing industry. In educational settings, one can illustrate them using the model experiment on flour dust explosions. The explosion pentagon describes the condition...

The paper examines the importance of involving chemistry teachers in continuous professional development programs that also include development of learning materials in chemistry. Chemistry teachers who were involved in ...

This article has two aims. First is to introduce an evidence-based research-oriented chemistry teacher education study program developed and applied at the University of Helsinki (Finland) since 2001. The study program i...

This study aims to develop an alternative method for the determination of the chemical equilibrium constant (Kc) of thiocyanatoiron(III) complex ion, based on colorimetric analysis of smartphone-captured images. The vari...

This study investigated the effectiveness of integrating virtual laboratories into secondary school chemistry instruction on acid–base equilibrium concepts in Addis Ababa. It examined the impact of simulation-based vir...

This study evaluates the combined analysis of a two-tier test and Rasch analysis on learning assessment. A quantitative exploratory design was conducted on the validated 10-item Particulate Nature of Gas Concept Test (PN...

Generative artificial intelligence (Gen AI) has become increasingly important in education. However, its application for direct formative assessment represents an emergent area of inquiry. This mixed-methods study invest...

The opening phase of a lesson can strongly influence students’ readiness to learn, yet teachers often receive limited, delayed feedback on the quality of this phase. This study examines which opening-lesson features ar...

Students in A-Level and IB, and similar high-school curricula are expected to understand nucleophilic substitution mechanisms (SN1 and SN2), yet many rely on memorization because curricula do not provide a conceptual bri...

Science shows, such as chemical Christmas lectures, are a 200-year-old tradition in science communication. While their entertainment value is evident, their educational impact remains less understood. This study examines...
