The Anthropocene is a geo-stratigraphic unit of the upper Earth's layers, impacted by human disturbances, but also humankind's historical record, and children's place to live on. It is an unfinished narrative. This study explores how garden and soil-related activities with kindergarten children, guided by well-informed teachers, may have the…

So far, instruments to measure genetic literacy that encompass global genetic issues are limited. In addition, instruments that assess practical knowledge and comprehensively evaluate genetic literacy skills have yet to be developed. Therefore, this research aimed to develop, validate, and improve an instrument based on a new conceptual framework…

The concept of black body is of primary importance in studying the energy transfer of thermal electromagnetic radiation at all wavelengths. Several physical bodies like incandescent lamps, electric heaters, stoves, the sun and the other stars, microwave background radiation, etc., are considered to be black bodies as their radiation spectra fits…

In this study, the aim is to determine pre-service teachers' conceptual understanding of the standing wave concept. Pre-service teachers' conceptual understanding of the standing wave concept was determined through the phenomenological pattern, and the aim was to lay bare how they made sense of this phenomenon, how they perceived and experienced…

This study investigated the comparative effectiveness of pedagogical pattern of running a course and talk-chalk methods on senior secondary school students' achievement in waves. It is triggered by reports of persistent students' low achievement in physics contributed largely by students' poor performance in waves-related items. It adopted the…

Marine science picture books have the capacity to shape what young people know and how they think about ocean environments and marine biodiversity. Despite academic scholarship on marine science literacy broadly, relatively little has been done to study the role of picture books in teaching children about this topic. This paper is an attempt to…

Time is a central concept for astronomy, yet how it is communicated in educational contexts has received insufficient attention in the literature. This study explores how time-related concepts are communicated in the planetarium, by analyzing 34 different planetarium sessions held in a diversity of Portuguese institutions. Sessions were video and…

Novel technology has been applied to improve students' learning abilities in different disciplines. The research in this field is still finding suitable methodologies, tools, and evaluation mechanisms to devise learning frameworks with high impact on students' performance. This article describes an instructional method to perform Newtonian physics…

The aldol condensation reaction is one of the many synthesis reactions carried out in second semester organic chemistry laboratories. This reaction was integrated into a novel experiment requiring students to synthesize dibenzalace tone derivatives using the crossed-aldol condensation by reacting different types of benzaldehyde derivatives with…

In undergraduate chemistry curricula that include computational modeling, students may gain first-hand experience in both introductory and advanced applications of this technique. However, although students can be exposed to the predictive power of computational work, its capabilities are often limited to determining the intrinsic properties of…

Popular accounts of exciting discoveries often draw students to physics and astronomy, but at the introductory level it is challenging to connect with these in a meaningful way. The use of real astronomical data in the classroom can help bridge this gap and build valuable quantitative and scientific reasoning skills. This paper presents a strategy…

Due to its distinct phenotype and relatively simple inheritance pattern, the phenylthiocarbamide (PTC) loci is frequently utilized in teaching laboratories to demonstrate genetic concepts such as Mendelian inheritance and population genetics. We have developed a next-generation sequencing and bioinformatics approach to analyze the PTC gene locus…

This research draws on Legitimation Code Theory (LCT) to understand the epistemic dimension of the higher education classroom discourse of a professor who is well evaluated by his students. In expository science classroom discourse, concepts are loaded with different meanings, a process that is called "condensation of meanings" in LCT,…

This article presents and discusses the results of a study that investigates university students' comprehension of the concept of molar concentration, following teaching and evaluation of the subject. The specific problems underlying learning of this concept have not yet been focused on in sufficient detail or depth. A "Reasoning with…

Students often struggle to make interdisciplinary connections and cite a lack of opportunity to make such connections. To address this issue, we are developing activities aligned with the framework of three-dimensional learning that provide students with opportunities to make connections between chemistry concepts and biological phenomena. Here,…
