Scientists rely heavily on tree-ring records to better understand climate variability of the past millennium. Tree rings can also be utilized to give students a window into paleoclimate research, the methods scientists use, and the importance of scientific findings. Here, we present five online labs that introduce undergraduate students to the…

This paper presents strength and thermal studies, as well as an analysis of the design material for the development of a nanosatellite model. By using the SolidWorks software environment, an effective solid-state finite-element model of a nanosatellite are developed, on the basis of which the stress-strain state of the nanosatellite is analyzed,…

Science and technology education necessitates teaching and learning experiments involving electronic circuit construction and measurements using experimental equipment. In this study, a novel cross reality system for learning physical circuit construction and performing virtual experiments using virtual experimental equipment with mid-air haptics…

Multimodal representations play crucial role in students' learning process that students communicate their ideas by using representations. The main aim of this research is to determine the effects of multimodal representations on students' science learning. Quasi-experimental with pre-test and post-test design was used in this study. This study…

Teachers often rely on curricular materials as support for implementing reform-based science practices and as educative materials to continue developing ways in which they teach and approach science. Therefore, it is important to understand how teachers develop and use curricular materials and how they learn from their experiences. However, we…

The most important source of knowledge in primary school teaching is the textbook. This research aimed to determine the differences in graphic illustrations in the contents of natural sciences in a regular textbook and a textbook for children with special educational needs in the Republic of Serbia. As the number of subjects that deal with the…

The aim of this research is to identify pre-service science teachers' experiences during the simple electrical circuit establishment process, points they were challenged with, and developed strategies they used against the challenges they were experimenting with this process. In this study, embedded single case study, which is one of the…

Multiple choice questions are traditionally expensive to produce. Recent advances in large language models (LLMs) have led to fine-tuned LLMs that generate questions competitive with human-authored questions. However, the relative capabilities of ChatGPT-family models have not yet been established for this task. We present a carefully-controlled…

Co-design is an increasingly common process for curriculum development in science education, where teachers and researchers work together to create curricula, drawing on mutual knowledge and expertise. In efforts to understand this process, I looked at design dilemmas that occurred during design meetings and categorized the ideas that emerged in…

This qualitative descriptive analysis aims to interpret the complexity of the science items that are integrated with environmental sustainability content. This research was conducted on science test items in the 2013 Curriculum student science textbooks released by the Ministry of Education and Culture of the Republic of Indonesia. This study…

Although science education, including biochemistry and molecular biology education, starts before students commence university, for many students, undergraduate programs are their first real introduction to biochemistry and molecular biology. Students often report that biochemistry and molecular biology are relatively difficult topics hence the…

STEM (Science, Technology, Engineering, and Mathematics) education is an interdisciplinary approach aimed at enhancing students' understanding of these disciplines and fostering critical thinking and problem-solving skills. This study investigates the experiences and perceptions of 20 third-year pre-service science teachers (PSSTs) participating…

Nature of Science (NOS) has been enumerated as one of the important elements in education because robust conceptions of NOS is essential for individuals to be considered as scientific literate. As teachers are vital in imparting sound NOS conceptions to their students, they must possess sound NOS conceptions. However, studies have shown that…

Twenty-first century chemistry education researchers reported challenges in chemistry education pertaining to high school chemistry teaching-learning outcomes. Even though all studies intended to improve chemistry teaching-learning outcomes, unfortunately the impact of chemistry education research found not to be much encouraging. A few of these…

This paper describes a preliminary study of how computational methods allow us to know more about citizen science and its connection with education. Citizen science is a practice involving a general public in scientific tasks and generating knowledge and scientific results. Previous studies have shown that the education sector can take benefit of…
