Xerogels, exemplified by silica gel, are substances formed by drying gels, resulting in a loss of their internal solvents. Understanding the production and properties of xerogels is crucial, owing to their widespread applications. Xerogel chemistry is widely utilized in several substances; therefore, understanding this chemistry is extremely…

Electrochemistry plays a crucial role in our everyday lives. It allows us to power our phones and cars and allows for the real-time monitoring of blood glucose levels. While electrochemistry is of vital importance and is a long-established field of chemistry, it is often neglected in modern curricula for STEM courses. Herein, we show that hands-on…

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…

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…

This qualitative case study delved into students' understanding and positioning while they participated in solving an authentic, conceptually-based problem in a high-school chemistry class. Verbal and nonverbal cues, particularly gestures, offered broader awareness of students' engagement in sensemaking during the learning experience. The…

The problem addressed by this study was to determine the influence of high school start times on students' academic achievement and precisely how this impacts the scores students received on the Biology I End of Course Exams. It also determined if there was a difference in influence between males and females. This was determined by comparing the…

Past research repeatedly revealed students' struggles to understand chemical equilibria, especially concerning their dynamic nature. Black-box simulations have proven to be helpful here. However, the effect is strongly dependent on the quality of teaching, the design principles of which are not yet fully known. One aspect of debate concerns the…

Triboluminescence is a fascinating phenomenon that can engage students' interest in chemistry. However, safe, cost-effective, and accessible laboratory experiments featuring highly triboluminescent substances are limited. To bridge this gap, we present a simple, rapid, semimicro test tube preparation of the visually engaging manganese complex…

With the rapidly increasing demand for STEM skills, many scientists, mathematicians, engineers, and technology professionals encourage students to pursue STEM careers. However, communicating science to lay audiences is challenging due to complex scientific terminology. This qualitative research aimed to demonstrate how an exemplary scientist, Dr.…

Many high school students learn about nutrient cycling during biology, environmental science, and agriculture classes. These lessons often focus on soil and plants, and nutrient cycling is usually taught independently from climate change. Scientists know that animals, including fish, can have strong effects on nutrient cycling (i.e., nitrogen and…

One of the efforts to improve the quality of education in Indonesia is through learning by integrating environmental culture. Environmental culture can be packaged in more meaningful learning through biological literacy. This study aims to assess the biological literacy skills of high school students using local potential-based biodiversity…

Development of scientific explanation abilities in students is an important aspect in science education. However, traditional learning methods such as textbooks and PowerPoint presentations are often less effective in improving skills due to lack of student interactivity and involvement in the learning process. This study aimed to analyze the…

The CRISPR/Cas9 system opens new horizons (M. Adli, Nat Commun, 2018) regarding genetic modifications of living organisms but also as an in vitro tool in laboratory protocols. Therefore, it boosts possibilities in research and future medical treatments. As the controversial claim of genomically edited babies by He Jiankui (Cyranoski D., Nature,…

Background: Developing upper secondary school students' understanding of the nature of science and technology are important priorities in educational systems worldwide. More research is needed to better understand the conditions under which teaching and learning of epistemological insights become possible, as well as the tools that are necessary…

The purpose of the study is to see if there is a significant difference in chemistry exam achievement growth for 10th grade students in classes with problem-based learning compared with those students in classes with direct instruction. The state in which the study was conducted is developing new standards that are challenging students more than…
