This research paper aims to propose a novel didactic sequence inspired by an historical/epistemological study of the evolution of spectroscopy and in particular of colorimetry. The working principles of the historical color comparators and the visual color matching method, first proposed by Duboscq, stimulated us in the development of a five-step…

The purpose of this investigation was to evaluate the influence of science volunteering initiatives on the experiences of women and their subsequent inclination to continue volunteering. The research sought to examine the impact of particular social cognitive variables on their eagerness to partake in events and organizations. The study…

This study employed a mixed-methods design to investigate the impact of activities developed by the Ministry of National Education (MoNE) on the scientific creativity and scientist perceptions of gifted 5th-grade students. The research used a one-group pretest-posttest design with a sample of 22 students from a Science and Art Education Centre in…

The COVID-19 pandemic affected a large range of in-person education activities in Colombia. This created great limitations in academic performance for students with reduced access to communication technologies and deepened the educational gaps in the country. This was particularly true for sciences such as biochemistry. In Colombia, molecular…

The aim of this study was to examine the effects of STEM activities on students' attitudes towards STEM and problem-solving skills by taking their components into account. An experimental design with pretest-posttest control group was applied in the study. Quantitative and qualitative data collection tools were used. The participants of the study…

The ability to elucidate the structure of organic compounds from their nuclear magnetic resonance (NMR), infrared (IR), and mass spectrometry (MS) spectra is an essential skill, particularly for those engaged in the fields of synthetic and analytical organic chemistry. Spectral analysis constitutes a fundamental component of the curriculum for all…

Investigating students' thinking in classroom tasks, particularly in science and engineering, is essential for improving educational practices and advancing student learning. In this context, the notion of "Ways of Thinking" (WoT) has gained traction in STEM education, offering a framework to explore how students approach and solve…

This study investigates the influence of inquiry-based laboratory activities on the understanding of heat concepts and the self-efficacy beliefs of pre-service primary teachers. Recognizing that both scientific literacy and teaching efficacy are critical for effective science education, this research aims to determine how inquiry-based laboratory…

The quality of teacher-child discourse affects children's development and learning. Our study aims to explore teacher-child discourse during planned science activities (PSAs) in Vietnamese preschools. This research is essential to understanding the reasons behind Vietnamese children's low level of scientific skills and to exploring the dynamics of…

Tangible teaching aids can provide a valuable supplement to traditional textbook-based learning of fundamental STEM concepts. 3D-printed templates detailing the construction of simple parallel and series circuits were incorporated into the lesson plans for 6th-grade introductory physics. Aiming to introduce the concepts of junction and loop rules…

This work reports the development and application of an analytical tool for the analysis of the formation of the scientific mind of students who took part in inquiry activities, based on the philosophy of Gaston Bachelard, in a Chemistry Club. For the construction of the analytical instrument, an extracurricular course was offered to first-year…

This meta-analysis explores the impact of informal science education experiences (such as after-school programs, enrichment activities, etc.) on students' attitudes towards, and interest in, STEM disciplines (Science, Technology, Engineering, and Mathematics). The research addresses two primary questions: (1) What is the overall effect size of…

Molecular Cell Biology (MCB) should be taught according to the scientific practices, avoiding cumulative and memory knowledge construction, but favoring scientific thinking. A way to achieve this goal is to apply activities involving scientific news, which construct knowledge through significant learning and the development of critical thinking.…

The aim of this study is to determine the effect of sustainable environmental activities aimed at preschool children on raising environmental awareness. The research was conducted at Baglarbasi Kindergarten in the Haliliye district of Sanliurfa Province, Turkey. A total of 101 children aged 4-5 years participated in the study. Sustainable…

Understanding experimental design (e.g. control of variable strategy or CVS) is foundational for scientific reasoning. Previous research has demonstrated that demonstrations with cognitive conflict (e.g. asking students to evaluate and explain different experimental designs) are effective in promoting children's scientific reasoning, however, the…
