This study aimed to elucidate the perceptions and mental models of 5th-grade secondary school pupils about shadows, solar eclipses and lunar eclipses through drawings. A total of 443 pupils studying at public schools in Afyonkarahisar participated in the study. It was conducted as a case study, one of the qualitative research designs. As a data…

The Native American Medicine Wheel is a powerful tool to bring alive curricular connections from science and history to mathematics and civics as part of schoolyard gardening initiatives. As a living lab these gardens also serve as valuable tools to reinforce lessons on habitat enhancement. However, deeper lessons connected to the cultures of…

The present study aimed to develop, introduce, and conduct an activity for the integration of augmented reality to the jigsaw IV technique in a planned and systematic manner. The activity developed for secondary school students is related to the "Pure Substances" subject which it is included in the "Particulate structure of…

The research examined the effects of hands-on teaching strategy on senior school learners' performance waves in Ilorin, Nigeria. Senior secondary school (SSS2) science students were sampled at intact classes using a purposive sampling technique. Researcher-designed instructional packages on waves and Physics achievement test on waves (PATW) were…

Live video web-streaming via an electronic field trip (EFT) format can connect youth with scientists working in a variety of settings. Previous research indicated interactions with scientists can change children's perceptions of science, technology, engineering, and mathematic (STEM) careers. We conducted an arts-based study to examine an EFT's…

The "Evolving 5-19 Biology" report (RSB, 2021) presents eight key recommendations and a framework for the development of biology curricula for ages 5-19. The framework proposes organising the curriculum in 23 coherent themes that form learning progression pathways. These pathways build answers to seven 'big questions' related to big…

This article reports on the development and piloting of a German version of a concept test to assess students' conceptual knowledge of density. The concept test was administered in paper-pencil format to 222 German secondary school students as a post-test after instruction in all relevant concepts of density. We provide a psychometric…

In recent years, more and more systematic research has been conducted in science fields, focusing on identifying alternative ideas that the students have for essential concepts and principles of physics. This has resulted in the production of essential and valuable international bibliographic information in various science fields, including…

This paper, presented in three parts, overviews the current understandings of the Earth System and the relatively recent interdisciplinary field of Earth System Science (ESS) from a school education perspective. The representation of ESS in the Australian Curriculum is explored through the Cross Curriculum Priority area of Sustainability and the…

Children are intrigued by switches that power a light source and by items that reflect light and sparkle, and they take notice of personal shadows cast on the playground. Many STEM fields draw upon understanding of light and shadow, such as astronomy, biology, engineering, architecture, and more. This book shows teachers how to engage children…

This study aimed to examine the opinions of the instructors who work at GUHEM (Gökmen Space and Aviation Training Center) on the exhibition's content, how the exhibition spaces contribute to science education, especially astronomy and aviation, and the types of visitors who frequently visit the center. Nine instructors from GUHEM's science centers…

Hydrogen is a sustainable and climate-friendly storage for renewable energies and can directly be generated from sunlight, e.g., by photocatalytic water splitting. This article presents the photocatalytic hydrogen evolution using LED irradiation of an aqueous ZnS particle dispersion with Na[subscript 2]S and Na[subscript 2]SO[subscript 3] as…

The purpose of this mixed-method study is to determine the effect of integrating Engineering design on high school students' scientific reasoning and science achievement. Thirteen eleventh-grade students participated in this eight-week long study. The intervention engaged students in the Engineering design of a functional Dialysis model. Students…

The use of interlocking toy building blocks (e.g., LEGO) as teaching modules with a focus on the topics in organic chemistry is presented. Interlocking building blocks were assembled on a baseplate to depict chemistry concepts of hydrogenation of alkenes, hydration of alkenes, Markovnikov's rule, cis and trans isomers, hydrogen bonding, optical…

A simple experiment was developed to introduce students to the sustainable procurement of water through fog harvesting that can be used for drinking or irrigation purposes. Access to clean water and sanitation is problematic particularly within dry regions such as in areas of Peru, although there is a significant amount of fog in the mountainous…
