A confluence of circumstances in educational policy and teacher preparation have placed a low priority on elementary science teacher preparation. Historically, a lack of elementary science teachers' subject matter knowledge and pedagogical knowledge has negatively impacted science teaching self-efficacy, which is linked to many teacher and student…

In recent years, single-subject experimental courses have not been able to meet the demands of the comprehensive development of life sciences. This study is based on two fundamental disciplines, molecular biology and metabolomics, with the analysis and intervention of tumor-related genes as the starting point. A comprehensive experimental course…

An increased reliance on nanotechnology and recent developments in materials fabrication coincide with a greater prevalence of 3D printers in high schools. We developed this lesson to foster an exploration of interdisciplinary fields and to increase access to recent advances in materials chemistry through two different learning modules. The lab…

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…

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…

As elementary schools across the U.S. continue to adopt new science education reform, attention is needed to understand how teachers make sense of using engineering design to teach science in their classroom settings. This study examined fourth-grade teachers' sense-making with learning to integrate engineering design-based science instruction and…

Recent national reforms focus on learning disciplinary core ideas through engaging in science and engineering practices. These reforms also call for students and teachers to use crosscutting concepts (CCCs), or analytical lenses, that support scientific sensemaking and connections across disciplines. The "Framework for K-12 Science…

This research evaluated the implementation of a climate science curriculum intervention for students in Grades 4 and 5, including those who were typically achieving and those with difficulties in mathematics, reading, or both. Pre- and posttests of measurement and climate change science concepts were administered at the beginning and end of each…

Research indicates that students frequently struggle to apply their knowledge of organic compounds' structural theory to understand the concepts related to resonance and learn to use curved arrows to write resonance structures. Educators have developed educational tools and methodologies to aid students in overcoming their learning difficulties.…

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?…

Background: Foundation phase teachers are not science specialists; however, they are expected to teach science. It is important that research determines where teachers face challenges in teaching science in order to assist them to bridge the gaps and to improve their competence in teaching science. Aim: The aim of this research was to explore…

Research suggests that it is challenging for elementary students to develop conceptual understanding of trait variation, inheritance of traits, and life cycles. In this study, we report on an effort to promote elementary students' learning of hereditary-related concepts through scientific modelling, which affords opportunities for elementary…

This study aims to investigate the comprehension levels of classroom teacher candidates about the key concepts of Life Science Curriculum. The study was carried out within the qualitative research approach and descriptive survey model was adopted. The sample of study consists of final year 114 classroom teacher candidates who are studying Primary…

The research reported on here is part of a larger study exploring the alignment of the intended, implemented and attained curriculum with regard to practical work in the Zimbabwean A-level Biology curriculum. In this paper we focus on the alignment between the intended and implemented A-Level Biology curriculum through the lens of teachers'…

The "Next Generation Science Standards" (NGSS) challenges science teachers to think beyond specific content standards when considering how to design and implement curriculum. This lesson, "Windmills by Design," is an insightful lesson in how science teachers can create and implement a cross-cutting lesson to teach the concepts…
