The purpose of this case study, informed by a Lakatosian perspective, is to identify how an alternative conception that originates in present learning but is related directly to subsequent learning contexts can be constructed. Before the study, one of the authors found by accident that a student who had learned about Avogadro's principle and…

This Article aims to share the results of a project that was developed with 80 students from Technical High School of Professional and Technological Education (PTE) at an institute located in the northeast of Brazil. The students discussed the global overview of fuel production and use, and how the introduction of green hydrogen into the market…

In this work, we introduce high school students to renewable energy through the exploration of the pyrolysis process, focusing on the conversion of lignocellulosic biomass into bio-oil. Students undertake a sequence of straightforward experiments in four sessions, using a handmade reactor and various types of biomasses. Outcomes such as yield…

While researchers have stressed the importance of engaging students in activities that enhance their reasoning practices, few have scrutinised the factors that impact the reasoning involved in such activities. We explored the role of attitudes in student-group interactions concerning a climate change-related socio-scientific issue and how those…

The distinction between pressure in a liquid and in a gas is often treated in a cursory way, or not treated at all, even in university level textbooks. Most texts fail to point out the relation between pressure and density in a gas as compared to pressure in a--virtually incompressible--liquid. In many instances this also results in a dismissive…

In recent years, solar-powered photocatalytic water splitting for hydrogen production has drawn great attention as a method to supply clean energy and reduce environmental pollution. This approach, driven by solar energy to synthesize hydrogen gas, is completely renewable and can be used to power hydrogen fuel cells to effectively solve the global…

The study aims to present how to apply a STEM activity in which physical computing principles and computational thinking processes are used as a differentiation practice to be used in the education of gifted students. In the activity, the students designed smart packaging that will provide healthy long-term storage of foods to solve the greenhouse…

Young people around the world show considerable engagement with climate change. How can education draw on this engagement in order to benefit students and society? In this article, we discuss how inquiry-based dialogues can support students' development in their societal engagement. We argue that such dialogues should include real-world problems…

Alternative conceptions become obstacles in physics. However, it is difficult to find instruments that can identify students' alternative conceptions, especially in gases kinetic theory (DIGaKiT). The purpose of this research was to development of diagnostic instrument of DIGaKiT in identifying students' alternative conceptions by Rasch analysis…

We often say food and fuels "contain" energy. It is more accurate to say that energy is stored in the "fuel-oxygen system" generated during photosynthesis. It is definitely "not" stored in fuels or food (except for the very small amount of energy that can be obtained during anaerobic respiration). Aerobic respiration…

The aim of this study was to develop students' chemical literacy by integrating dilemma stories into a Science, Technology, Engineering, Arts, and Mathematics (STEAM) project on petroleum. Chemical literacy can help students face future challenges by applying what they learn about chemistry subjects at school to solve problems in their daily…

Many students may not be aware that renewable biological materials can be converted into multiple bioproducts and biofuels using a biorefinery process, a more sustainable alternative to conventional crude oil refineries. By using waste from pineapple, a plant material that most students are familiar with, a biorefinery can be modeled to…

Technology and validation methods for producing biodiesel have been updated and have kept advancing. Creative raw materials used in producing environmentally friendly biodiesels have also attracted interest from scientists. Thus, learning and teaching methods on biodiesel production at the high school level need to be up to date. However, there…

Using engineering design practices, student groups reverse engineer their own oil cleanup techniques and processes.

Many organizations experience crises at some point in their existence. Some are slow-moving and allow organizational leaders to anticipate and prepare for them, while others are more sudden, such as natural disasters or tragedies, and threaten the organization's people, property, results, and reputation. Leading change during such crises requires…
