No scientific concept in the twenty-first century has garnered more attention from scholars outside the scientific community than the Anthropocene. Despite the official rejection by the geological community in March 2024 of the proposal for an Anthropocene Epoch as a formal unit of the Geological Time Scale, it is expected to remain an invaluable…

Calculating analytical uncertainties as a part of method validation is a relevant aspect of field and laboratory practices in instrumental analytical chemistry subjects, which usually require complex algorithms. This work describes the development and didactic use of an automatic and straightforward informatics tool, implemented in an Excel macro,…

The construction of scientific explanations is recognised by science education researchers and curriculum developers as one of the core epistemic practices in which students should acquire proficiency. However, little is known about the knowledge and skills that teachers must and do put into practice to successfully engage their students in…

This study aimed to explore how proficient science teachers facilitate sensemaking moments in the classroom. Specifically, the study sought to describe how science teachers facilitate sensemaking during lesson discussions, exploring the factors that influence their facilitation, and developing a model that will guide proficient science teachers in…

The ability to relate physical concepts and phenomena to multiple mathematical representations--and to move fluidly between these representations--is a critical outcome expected of physics instruction. In upper-division quantum mechanics, students must work with multiple symbolic notations, including some that they have not previously encountered.…

Background: This research explores thinking and teaching strategy in sciences teaching by analyzing 2027 research articles from the Web of Science. It is anticipated that groups of keywords, writers, and universities will highlight patterns, offer advice to scholars and teachers, and add to the body of literature already available on the topic.…

In a traditional lecturing environment, students possess limited agency in accepting or rejecting information provided by teachers. A higher level of student agency involves opportunities and actively identifying uncertainties and collaborating with peers to deepen understanding within the classroom community. Teachers play a crucial role in…

Traditional approaches to intelligence often neglect the diverse cognitive profiles of learners, potentially limiting the inclusivity and effectiveness of educational practices. This review article examines the application of Howard Gardner's Theory of Multiple Intelligences (MI) within the context of biology education, with a particular focus on…

The goal of the research was to find out the effect of using living animal in teaching on remembering and understanding acquired knowledge in students with special educational needs (SEN). In our experiment, students with SEN (n=24) were compared with students without SEN (n=56). The design of the research was experimental. The research tool…

As the size of a nanoparticle is reduced, the fraction of surface atoms increases. It is interesting to note that various chemical and physical properties depend on the fraction of surface atoms. One of the most obvious questions that arise is how could one possibly estimate the fraction of surface atoms in a nanoparticle? Herein, we discuss…

Chemistry and Chaos is a role-playing game that was developed to teach a wide variety of chemistry topics. The game uses the traditional role-playing framework to present material in an engaging and interactive format. The students take on the role of a particular type of chemist while the instructor guides them on an adventure to test their…

The United States lags behind other countries in science literacy at the 4th, 8th, and 12th grade levels. Subsequently, this is seen at the higher education level, especially with gateway science courses. BIO 103-General Biology I is a gateway course at Lion University. Passing this course is crucial for students to progress in several science…

Teacher knowledge is vital to provide meaningful learning opportunities. In this case study, a secondary education teacher's knowledge about how to teach the concept of ecosystems from a river is explored. A category system drawn from the literature about science teacher knowledge was used for the analysis. Science teaching requires teachers to…

Mechanistic explanations, aiming to disclose details of entities and their activities, employ the act of unpacking which, inherently and paradoxically, produces explanatory gaps--pieces of undisclosed, undetailed mechanistic information. These gaps, termed explanatory black boxes, are often perceived as counterproductive to the teaching of…

Previous research has shown that in prehigher education stages, inquiry-based teaching is not sufficient for forming a mature understanding of the nature of science (NOS). However, there is relatively little research conducted on colleges. Inquiry-based teaching should not overlook cognitive frameworks, as students' limited scientific reasoning…
