The study and analysis of enzymatic reactions are essential for characterizing various biological systems. As part of these procedures, it is important to understand how to quantify the biological activity of these proteins in terms of enzymatic activity. This work proposes a general equation for determining enzymatic activity based on…

Modern and Contemporary Physics is an important component of civic education for senior high school students, as topics such as Relativity and Quantum Physics connect with everyday life and foster abstract thinking and critical skills. Yet, these themes are often absent from high school curricula. Among them, Einstein's General Relativity Theory…

The rapidly evolving educational landscape allows, and often demands, the integration of innovative digital approaches into the curriculum. Whether the course is conducted in-person, online, or hyflex, synchronous or asynchronous, the wide range of available digital tools and platforms now offer multi-faceted learning experiences designed to…

How science is traditionally taught and presented in westernized classrooms, Western Modern Science often does not offer creative and culturally sustaining pathways for students with diverse multicultural backgrounds to view science as a beneficial resource for their worldview, values, and funds of knowledge. This conceptual position paper…

Background/purpose: This study aimed to identify the impact of teaching science based on John Zahorek's model on the acquisition of scientific concepts among seventh-grade female students. Materials/methods. It was based on the quasi-experimental method. The study participants, comprising 58 seventh-grade students, were intentionally selected from…

This work presents a modernized lab module for nitrite analysis using a novel probe, AAC (4-(2-aminophenyl)-7-(diethylamino)-2H-chromen-2-one, C[subscript 19]H[subscript 20]N[subscript 2]O[subscript 2]), offering a safer and more sensitive alternative derived from recent research. The 12-h module follows a three-stage structure (Basic…

School principals play a pivotal role in directing students' classroom educational experiences. However, in the USA, many elementary principals (serving youth 5-12 years old) have had few formal experiences with professional development or coursework that centers on current standards for quality science instruction as guided by the "Framework…

Vocabulary knowledge plays a critical role in supporting text comprehension and broader learning across the school day. While school offers opportunities to build vocabulary knowledge, studies have shown that very little time is devoted to vocabulary instruction at the elementary level. This may be, in part, because educators commonly report being…

Science teacher education literature has emphasized the importance of prospective teachers' prior knowledge of their K-12 experiences as a key factor influencing their professional development as future science teachers. The purpose of the study was to identify the teaching practices in prospective teachers' prior knowledge of science instruction…

Education in organic chemistry is highly reliant on molecular representations. Students abstract information from representations to make sense of submicroscopic interactions. This study investigates relationships between differing representations: bond-line structures, ball-and-stick, or electrostatic potential maps (EPMs), and predicting partial…

Understanding teachers' experiences as they lived them and as they told them is important for conceptualizing a well-rounded view of the state of science education and the role teachers play in it. Journey mapping, a way of visualizing one's processes and experiences as they progress towards a goal, is a tool with the potential to capture…

Machine learning (ML) is extensively applied in chemistry, particularly in vibrational spectroscopy. However, few teaching examples effectively demonstrate the capabilities of ML in classifying polymeric materials, exhibiting subtle spectral differences that elude visual discrimination. This study presents a teaching example specifically tailored…

Field-Based Practicum (FBP) about Pterydophyta diversity material in Low plant botany learning is very important, even though the facts in the field show that FBP is still minimally carried out. This research aims to utilize the potential diversity of Pterydophyta in the Tuban-Lamongan Pantura area as a support for FBP about low plant botany…

This study investigates preschool teachers' considerations for including digital tools in science teaching to develop children's learning of science content. Due to the ongoing digitalisation and demands in society, the utilisation of digital tools has increased significantly in educational settings. Recent research about digital tools in early…

Studies of both professional science practice and children's science learning show that care is not merely ancillary to disciplinary work but a core and generative constituent of science practice. In science education research, however, students' care is often overlooked. In this paper, we describe the expression of care across two STEM classrooms…
