This study investigated the science competencies that scientists and students perceived as important and their science-related experiences and analyzed them comprehensively using activity system framework in order to explore which competencies need to be emphasized more and what experiences and environments should be provided in school science…

The goals of the study were as follows: i) to design an active science learning activity on stoichiometry for grade 10 students, ii) to evaluate the academic achievement of grade 10 students after receiving an active science learning activity on stoichiometry, and iii) to investigate the perspectives of grade 10 students regarding an active…

A simple inquiry-based activity called "Fruit Puzzle" was designed to investigate high school students' understanding of the relationship between the concepts of density and solution concentration at a submicroscopic level. The first activity allowed students to predict whether five types of fruit would sink or float in water and asked…

To promote scientific literacy in school science, students need to learn key concepts in science, along with the nature of scientific knowledge and how it is generated. Ideally, this learning mirrors authentic scientific inquiry through student engagement in three key epistemic practices: flexibility and creativity, knowledge construction, and…

Italian high school students carried out some activities within career guidance actions organized by the Department of Chemistry of Sapienza University (Rome) in order to promote enrollments in a chemistry Bachelor's course, thus remedying the shortage of professional chemists. Novel didactic sequences have been designed to facilitate the…

Understanding how to interpret and manipulate large data sets is increasingly important today; however, this experience has been slow to trickle down to the typical undergraduate student. Here, we describe the implementation of a project-based learning experience that uses portable air sensors for the real-time measurement of carbon dioxide,…

Science popularisation festivals attract more and more people every year, showing that there is a need to satisfy public curiosity. Such events are good occasions to disseminate knowledge to a large audience. The results of scientific research bring advances for mankind. Since research mostly depends on public funds, it is important to gain…

In this study activities related to biotechnology and genetic engineering were prepared and their effectiveness on students' achievement, attitudes towards biotechnology, and self-evaluations were investigated. The activities were implemented in 10th grade biology course. The study utilized mixed method, with qualitative and quantitative data…

This study examines the opportunities presented to high school chemistry students through argument driven inquiry (ADI) and how these opportunities led to changes in student understanding. Lesson plans and videos were analyzed to determine how much time students spent arguing from evidence including constructing and argument board, discussing with…

How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

A hands-on design activity named "electrochemistry designette" that incorporates design thinking with the aims to strengthen electrochemistry concepts, introduce prototyping ideas, encourage student class participation, and foster creativity is presented. This active learning activity, which lies at the interface of design and…

Prior research on the significance of roles in collaborative learning has explored their impact when they are pre-assigned to group members. In this article, it is argued that focusing on assigned roles downplays the spontaneous, emergent, and interactional nature of roles in small task groups and that this focus has limited the development of…

Project-based learning (PBL) is an instructional approach to science teaching that supports the "Next Generation Science Standards" (Krajcik 2015; NGSS Lead States 2013). In a PBL lesson, students design and solve real-world problems or explain scientific phenomena. Students using a PBL model learn and retain more than those not using…

What is it really like to plunge into the world of science learning and teaching? Find out in this unique book. "Dive In!" grew out of a teacher-scientist project at the University of New Hampshire that promoted active learning and using science practices in the classroom. That experience yielded this book's reason for being: to provide…

Chaos theory is not present in the Italian school curricula and textbooks in spite of being present in many topics of classical physics and in everyday life. Chaotic dynamics, in fact, are involved in phenomena easily accessible to everyone or in events experienced by most people in their lives (the dripping of a faucet which keeps people awoken…
