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…

To make sense of our interconnected and algorithm driven world, students increasingly need proficiency with computational thinking (CT), systems thinking (ST), and computational modeling. One aspect of computational modeling that can support students with CT, ST, and modeling is testing and debugging. Testing and debugging enables students to…

Understanding the general ideas and methods of detecting molecular structures is essential in high school chemistry. However, there is a need for more practical activities in teaching. A hands-on activity was designed in this study, which uses flexible foam balls and long sticks such as knitting needles to imitate how scientists construct the 3D…

Teaching green chemistry within the K-12 classroom has a positive impact on attitudes and perceptions of chemistry in society for future scientists and professionals, resulting in safer, less hazardous chemistry experiments and demonstrations. The state of New York has taken advantage of the benefits that green chemistry provide in the classroom…

Raising scientifically literate citizens has been the main concern of the science education community. Socioscientific issues (SSIs) provide a context to facilitate individuals to expand their epistemic understanding and develop scientific reasoning skills such as evidence-based argumentation and consensus building. In this qualitative research,…

Few empirical studies in Science Education have investigated the contributions of integrating scientific practices such as argumentation and modelling. In this article, I examine the characteristics of high school students' argumentative dialogues in different modelling situations. From this, I discuss the influences of modelling and the nature of…

Recent research suggests that integrating model-based learning and socioscientific issue based instruction helps students construct meaningful learning in science classrooms. Thus, this paper presents a unit plan that integrates model-based learning and socioscientific issues. The focus of the unit is the white butterfly which is a local pest. A…

This study contributes to the literature by shedding light on students' learning by examining and comparing students' gestures in two educational contexts: geological field trips and classroom-based modeling activities. This study engaged 10 middle-school students in two different geological field trips and two classroom-based modeling activities…

Three cohorts of six pre-service Earth Science teachers (undergraduate majors in Earth Science Education) participated in summer research experiences focused on developing dynamic physical models of Earth processes to help middle and high school students understand complex concepts and confront misconceptions. The pre-service teachers used…

Modeling is a core practice in science and is a meaningful way to learn the subject. This article introduces a modeling-based approach that highlights the idea that modeling is an iterative process and integrates the fundamental parts of scientists' work and key suggestions for teaching through modeling. The lesson "The Structure and Function…

Learning about the Earth through geoscience education is important in order to make informed decisions about the future of the Earth. The aim of this study is to examine students' conceptual development on geoscience subjects based on inquiry-based learning. 7th grade students participated in this study. The researcher prepared lesson plans and…

Studies have shown that inadequate definitions of scientific concepts could complicate the learning of science and could prevent students from understanding the definitions of scientific concepts. The article provides a framework for defining scientific concepts in primary, secondary, and university education by proposing teachers draw attention…

Scientific knowledge is a primary resource that scientists use to shape their activities to make sense of natural phenomena. Support for students' adaptation of scientific knowledge can enhance their ability to make sense of the natural world. This study aims to examine how ecological concepts are used when students plan field-based modeling of…

Especially within the light of the current loss of biodiversity, we want our students to gain a better understanding of the issues at stake in order to take action and support plants and their pollinators. Many educational approaches focus on honeybees, disregarding the vast diversity in the context of pollination systems and the complex…

In this article, simple models of optical computing circuits (1 x 4 demultiplexer (DEMUX), 4 x 1 multiplexer (MUX), Boolean logic, and half-adder (HA)) are shown with mechanically controlled plane mirrors. Photographs of the proposed computational circuits are also shown. It is very useful for the school student to understand optical logic and…
