One way of triggering students' interest in chemistry is making chemistry education more meaningful. Four characteristics of meaningful chemistry education (MCE) were identified in projects that involved a redesign of curriculum materials: daily life context, the need-to-know principle, students' input, and the macro--micro connection. Chemistry…

Over the past few decades, the photographic process has slowly vanished from chemistry education in most schools. It happened due to vast changes in both technology and legislation. It is, however, helpful in demonstrating several concepts in natural sciences, bringing a bit of art into the subjects, and giving students an opportunity to express…

This study aimed to determine the utilization of research results of the selection of marine fungi for milkfish ("Chanos chanos") feed. The study was conducted in stages, starting with identifying the issues in the learning activities of biotechnology concepts, followed by experiments to identify research methods and products, selecting…

The understanding of analytical chemistry and its application in different areas of life science is something that should be encouraged for students studying chemistry, and also something that appeals to many students. Life science includes a vast variety of areas, out of which some are more easily approached in student projects. The chemical…

Chemicals are characteristic of chemistry education practices at all educational levels. The aim of this study is to explore teachers' didactic rationales when reasoning about the use of chemicals in their teaching practice. Experienced upper secondary chemistry teachers in Sweden were interviewed about their considerations regarding why, when,…

The concept of relative density is introduced in the middle school and high school curricula by an intuitive approach based on the phenomena of immersion and flotation. In high school, the same concept is taught as the ratio between the masses of two bodies of the same volume. This dichotomy of the concept of relative density between the two…

This study was conducted to compare the efficacy of Lecture-Based-Learning (LBL) and Cooperative-Learning (CL) in teaching 'classification of living things' to Senior High School (SHS) students in Tamale, Northern Region, Ghana. The study was conducted in two SHSs using two science classes offering Biology during the 2020-2021 academic year. A…

Science learning is an important part of the K-12 educational experience, as well as in the lives of students. This study considered students' science learning as they engaged in the instruction of scientific issues with social relevance. With classroom environments radically changing during the COVID-19 pandemic, our study adapted to teachers and…

This research integrates context-based learning and modelling. It presents a teaching-learning sequence (TLS) about the dissolution of gases in liquids using carbonated drinks as the context. The impact of the TLS is analysed in a longitudinal short-term study involving two groups of learners aged 13-14 years old (n=53). The results led us to…

Differentiated instruction (DI) is a teaching approach that aims to achieve learning for diverse students. This study reports on promoting STEM teacher candidates' (TCs') implementation of technology-enhanced DI in teacher education courses. The research questions are: (1) How do TCs develop digital video games (DVGs) to be inclusive of DI?, and…

The present study investigates the devaluation of specialised teaching knowledge and the prioritisation of general education based on competencies and skills at the secondary level in Brazil. The dissolution of the curricular disciplinary organisation poses a risk to teaching identities, and understanding how teachers constitute epistemic and…

How do people use objects and gestures to shape scientific argumentation? This paper engages the concept of "entanglement" as a heuristic for considering the potentials and constraints that gestures and materials create for interactants. Drawing on video recorded data from an academic-year-long linguistic ethnography of a high school…

Current student-centred, multilingual, active teaching methodologies require that teachers have continuous access to texts that are adequate in terms of topic and language competence. However, the task of finding appropriate materials is arduous and time consuming for teachers. To build on automatic readability assessment research that could help…

This study investigated the intersection of literacy instruction and high school science teaching in response to low proficiency levels in these areas and interest in pursuing STEM careers among U.S. high school students. Participants reported using close reading practices combined with inquiry-based science instruction to enhance students'…

In the landscape of U.S. education, the widespread adoption of the Next Generation Science Standards (NGSS) offers a unique vantage point for researchers to better understand teacher-, school- and classroom-level factors that advance reform initiatives in science classrooms. Addressing a gap in current knowledge, our study probes how secondary…
