Hydrogel is an interesting topic in polymer chemistry, which is closely related to daily life and advanced technology. In this paper, we report an activity to deliver hydrogel chemistry into middle school classrooms by undergraduates as a bridge between professors and students. During the activity, undergraduates act as a bridge to receive…

Ocean currents play an important role in regulating the Earth's climate by redistributing ocean heat around the planet. One important climate phenomenon that includes several large ocean currents is the Atlantic Meridional Overturning Circulation, which is the process of warm surface currents in the North Atlantic Ocean moving to the Arctic to…

To be able to support students' competence development in solving physics problems over the course of a lesson series effectively, teachers need a proper appreciation of students' deficiencies. As teachers commonly assess students' competence by means of written tests, teachers are challenged to interpret students' work on these tests and to…

Over the past several decades, policymakers, researchers, and practitioners have placed an emphasis on inquiry-based science and mathematics instruction in elementary school. While inquiry-based science and mathematics instruction can support student learning and engagement, teacher preparation programmes have experienced challenges in preparing…

The chemistry of metal-organic frameworks (MOFs) has the potential to introduce high school and undergraduate students to the fundamental chemical principles of structure and bonding, enhance the development of skills in synthesis and crystal growth, and promote hands-on experience with gas capture and host-guest chemistry of emerging materials…

The aim of the study was to investigate the effect of the Common Knowledge Construction Model (CKCM) on 10th-grade students' conceptual understanding of the buoyancy and density of liquids topic. Within a pre-experimental (one group pre-test/post-test) research design, this study was conducted with 22 of 10th-grade students. To collect data, the…

This report describes an activity that helps organic chemistry students to better understand organic molecules as 3-dimensional objects. To accomplish this goal, the activity employs a unique three-way combination of analyzing computer-generated 3-dimensional renditions of open access X-ray crystallography data, building physical 3-dimensional…

The 21st century learning leads to create new skill of students, so the Indonesian government offers the new curriculum. In vocational school, project-based learning for the subject of the "Ilmu Pengetahuan Alam dan Sosial" (IPAS) Project is required to increase the creativity of student. Informations about the perspective of vocational…

An Arduino-based system with a triple axis magnetometer chip may be used to plot both the strength and direction of the magnetic field of a magnet directly on a sheet of paper. Before taking measurements, it is necessary either to correct for or to eliminate soft and hard iron effects. The same sensor may be used to determine the presence of soft…

Some teenagers are exploring the outer perimeter of a castle. They notice a spy hole in its wall, across the moat a horizontal distance "x" and vertically up the wall a distance "y." They decide to throw pebbles at the hole. One girl wants to use physics to throw with the minimum speed necessary to hit the hole. What is the…

As the trend for English as a medium of instruction (EMI) increases, teacher self-efficacy to teach the contents of their teaching materials in an EMI context has become one of the major challenges. This study investigated the self-efficacy of Indonesian non-ELT pre-service teachers to teach in an EMI context. Two Indonesian non-ELT pre-service…

Retention and underrepresentation of diverse ethnic groups have been and continue to be problematic in the science, technology, engineering, and mathematics (STEM) disciplines in the United States. One foundational course that is required for all STEM majors is general chemistry. One way to increase retention and diversity in STEM majors is by…

Schools operated mostly in online mode in the last two years because of the COVID-19 pandemic and many teachers are now using digital tools in physical classrooms after the reopening of schools. We conducted an experiment on how smartphones can be used to reinforce biology lessons of seventh standard students (mean age = 12.22 years) in a private…

This study aimed to investigate research trends related to socio-scientific issues (SSI). The SSI articles analysed were from highest-rating five science education journals with the highest impact ratings, published between 2011 and 2022, including "Science Education" [SE], "Journal of Research in Science Teaching" [JRST],…

Teaching physical sciences in English as the Language of Learning and Teaching (LOLT) has presented numerous challenges, particularly for learners who are not proficient in the language. The South African government is increasingly considering the use of indigenous languages as the medium of instruction for subjects such as physical sciences,…
