Language, and thus scientific language, is essential for chemistry teaching and learning. To be able to successfully teach the scientific language of chemistry, the Chemish, (prospective) chemistry teachers need to possess pedagogical scientific language knowledge (PSLK).Thus, teacher preparation needs to focus explicitly on Chemish and its…

It is 157 years since Mendel presented his results on hybridisation in peas to the Brünn Society for Natural Science. The discipline of genetics has dramatically changed since then, with technological advancements revealing multifactorial causation and trait variability. Whilst none of this complexity featured in the discovery of classical…

This article introduces and contextualizes the content of this theme issue of "The American Biology Teacher" (ABT), which focuses on integrating elements of the history of science (HOS) in biology instruction. Such orientations can enhance students' understanding of core biological concepts and the process of scientific discovery by…

According to the author, the "Australian Curriculum: Mathematics (AC:M) requires primary school students to measure the attributes of angle, time, temperature, length, area, capacity and mass. This article outlines some misconceptions held by primary school students which appear to stem from them not understanding terminology concerning the…

This empirical study investigates the main features of curricula and contexts that favor or hinder the process of transfer of a teaching-learning sequence (TLS) from the designers' original situation to a host one. The specific research questions addressed were (RQ1) what were the changes made during the process of transfer in the new context?…

A national Task Force of 25 Australian physiology educators used the Delphi protocol to develop seven physiology core concepts that were agreed to nationally. The aim of the current study was to unpack the "physiological adaptation" core concept with the descriptor "organisms adjust and adapt to acute and chronic changes in the…

The purpose of this study is to explore the relationship between life sciences teachers' understanding of indigenous knowledge (IK) and their views of integrating Indigenous Knowledge in their teaching practice. A qualitative case study research approach was adopted, and purposive sampling strategy was used to select eight Grades 10-12 life…

This study examined a network of concepts used in the curriculum, textbooks, instruction, and assessment in relation to somatic cell division and investigated the alignment of science concepts used in them. Textbooks and teachers' instruction and evaluation questions were collected to analyse the alignment between the concepts and the conceptual…

The "Evolving 5-19 Biology" report (RSB, 2021) presents eight key recommendations and a framework for the development of biology curricula for ages 5-19. The framework proposes organising the curriculum in 23 coherent themes that form learning progression pathways. These pathways build answers to seven 'big questions' related to big…

Background: There is a growing view that 'Big Ideas of science education' are useful for teaching science but there is not much knowledge of how teachers work with them. Purpose: This study explores the conceptualisation and practice of the use of Big Ideas of science education by primary and secondary teachers in Chile. Sample: A total of 63…

Science education objectives in Brazil have evolved over time. Initially, the focus was on creating scientifically literate citizens who could relate scientific concepts to their daily lives. In 2017, the São Paulo City Curriculum for Natural Sciences was introduced to teach students scientific literacy through inquiry-based teaching methods. This…

This study investigates the challenge faced by eighth-grade students at Southern State Middle School in grasping abstract concepts within the domains of physical science, physics, and chemistry. This difficulty is manifested in their poor performance on summative assessments. A comprehensive analysis of state-provided data, in conjunction with…

This research is a needs analysis study aimed at developing a curriculum based on an interdisciplinary context-based learning approach within the 10th-grade physics course, focusing on the electricity and magnetism unit. The research was designed according to the case study model and data were collected from expert, teacher, and student sample…

The study of complexity is an important part of science education. This paper presents a pedagogical option that includes potentially feasible field solutions for complex science teachers. This work aims to examine how fieldwork has appeared in the international literature over the past five years and to explore the algorithms that can be used to…

Computational thinking is an essential skill in the modern global workforce. The current public health crisis has highlighted the need for students and educators to have a deeper understanding of epidemiology. While existing STEM curricula has addressed these topics in the past, current events present an opportunity for new curricula that can be…
