[This paper is part of the Focused Collection in Investigating and Improving Quantum Education through Research.] Instructors teaching upper-division quantum mechanics have had two primary options when it comes to textbook choice and thus curriculum sequence: starting with wave functions and the Schrödinger equation, referred to as "wave…

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…

This study responds to the demands of the rapidly changing landscape of education, the 21st century competencies and development of curriculum. Those competences are being interpreted all over the world resulting to differing curricular changes. In the Finnish National Core Curriculum 2016 they are presented as seven transversal competences that…

The performance of any economy is based on scientific knowledge and technological innovation. Consequently, a highly motivated workforce with skills in science and engineering is key to any prosperous economy. Science education has a critical role in providing scientific literacy to students, as well as in training young people to choose careers…

This action research case study explored the ability of three high school chemistry students to grow in their understanding of nature of science (NOS) during its explicit-reflective inclusion in two unit chapters on bonding (ionic compounds followed by covalent molecules). Students completed a pre, post and delayed Views of Nature of Science Form…

The merdeka curriculum is a curriculum whose learning structure is divided into two main activities, namely learning that refers to student learning outcomes in each subject and projects to strengthen the Pancasila student profile. A digital pocketbook is an electronic book that contains information in the form of text or images that can be…

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…

There has been a growing emphasis on integrating green and sustainable chemistry (GSC) into the curriculum. Unfortunately, there is yet to be a nationwide, uniform decision of which aspects should be included or how, leaving individual instructors or institutions to decide whether--and how--to address GSC knowledge. Furthermore, faculty nationwide…

We have developed a curriculum for the organic chemistry laboratory in which students draw on authentic usage of spectroscopy, spectrometry, and computational chemistry to explain chemical phenomena. This curriculum, which has been continuously refined over a decade, has been explored by many thousands of students and is scalable to small and…

To guide students to make reasonable decisions in the face of adversity and pressure, a new general course named 'Introduction of Life Education' was established. The course was organized based on the knowledge of biological science, with the integration of social scientific issues on life health, food safety, environmental protection and…

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…

A key part of the practice of chemistry is the analysis of chemical composition, including through gravimetric analysis and spectrophotometry. However, the complexity of doing multiple calculations to obtain analytical evidence, such as that required to determine an empirical formula, presents a challenge if such analytical methods are to be…

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?…

Post-apartheid South African curriculum reforms, from outcomes-based education (OBE) to the Curriculum and Assessment Policy Statement (CAPS), resulted in different challenges. Teachers, in particular those teaching Physical Sciences in the Further Education and Training (FET) phase from Grades 10-12, were expected to cope with changes and master…

This study aims to develop guidance materials on the topic of evaporation and boiling within the Science course, to use the materials with 5th grade students, and to find out the students' opinions about the implementation of these materials. The participants consist of 10 students studying in a public middle school in the 2020-2021 academic year.…
