Over the past several decades it has become increasingly important to understand nature of science (NOS) for scientific literacy in science education. Science education researchers have suggested using socio-scientific issues to create a context for that purpose. The present fast-moving coronavirus or COVID-19 pandemic as a socio-scientific issue…

Online multiple-choice instruments to diagnose students' understanding of science concepts are easily developed and administered to students using Google Forms. This article describes a web-based three-tier multiple-choice test for the formative assessment of students' understanding of chemical bonding. The results obtained can lead to follow-up…

The Meaningful Watershed Educational Experience (MWEE) is a curriculum framework designed to support students' Environmental Literacy (E-Lit) by promoting critical thinking about watersheds, but there is a paucity of empirical evidence in the literature to demonstrate its effectiveness in increasing E-Lit and a lack of understanding of what MWEE…

Research in the past decades has repeatedly revealed that first year university students struggle to understand two-dimensional projectile motion concepts. In contrast to high school, projectile motion frequently makes use of components and it requires at least a basic understanding of trigonometry concepts. To follow the lessons and generate…

Many mobile applications have emerged thanks to the technological developments that have taken place today. One of these applications is the augmented (virtual) reality application used on smartphones and tablets. Some augmented reality applications are being prepared using 4D-technology and transforming the virtual environment into real life. The…

Learning in high schools has used a lot of smartphone assistance to make it easier for students to understand the material explained by the teacher. However, with the many uses of smartphones in learning, of course, it must provide positive benefits to the ability of students, especially the science literacy ability. In this study, the objectives…

Teaching modern physics in high school is of increasingly importance as it can offer students a more realistic and updated vision of the world, and can provide an opportunity to understand the most recent scientific discoveries. In this context, general relativity (GR) occupies a prominent place, since it is related to astonishing scientific…

Gold nanoparticles are exciting materials in nanotechnology and nanoscience research and are being applied across a wide range of fields including imaging, chemical sensing, energy storage, and cancer therapies. In this experiment, students will synthesize two sizes of gold nanospheres (~20 and ~100 nm) and will create gold nanostars utilizing a…

Secondary science students still struggle to master scientific concepts and apply content-based knowledge. The instructional design behind the incorporation of innovative technology and the use of game-based learning (GBL) could be a key to increasing student acquisition of science knowledge. Using a mixed methods design, this study examined the…

One of the skills needed in the 21st century is critical thinking skills that need to be developed for secondary school students. Currently, upper-secondary students' critical thinking skills are still low. To overcome the problem, websitebased E-module learning media was developed using a STEM approach with a Problem-Based Contextual Learning…

ChatGPT is largely acknowledged for its substantial capacity to enhance the teaching and learning process despite some concerns. Based on the available literature, no study compares groups of students using ChatGPT and those who did not, more so in programming. Therefore, the main goal of this study was to examine how ChatGPT affects SHS students'…

In the 2021 legislative session, the Tennessee General Assembly enacted Chapter 170 of the Public Acts of 2021 (PC170, now codified as T.C.A. § 49-6-1012), which requires all Tennessee local education agencies (LEAs) and public charter schools to adopt an academic acceleration policy for grades 7-12 and establish criteria for student enrollment in…

Students' worksheets, as learning material, is important to achieve learning outcomes. This study aimed to develop students' worksheet, based on STEAM (Science, Technology, Engineering, Art, and Mathematics), on ecosystem topics to empower students' science process skills. The Research and Development used 4D model by Thiagarajan. Students'…

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…

The Physics Laboratory of the Hellenic Open University has constructed a small scale and low cost air shower detector suitable for operation inside the classroom or school laboratory ([mu]Cosmics detector). In this work we present some of the educational activities foreseen with the [mu]Cosmics air shower detector, as well as the assessment of a…
