Chemistry as the Central Science and Systems Thinking
Chemistry is often called the "central science" because it connects and supports many other scientific fields and societal issues. However, for chemistry to truly serve this central role, students need to develop systems thinking skills. This means understanding how chemistry links to earth systems, society, and global challenges, rather than just learning isolated facts. Educators are encouraged to shift towards teaching that helps students see these broader connections, especially through green and sustainable chemistry approaches, to prepare them for real-world problem-solving Mahaffy2019Mehta2022Reyes2025.
Chemistry’s Role in Sustainability and Resilience
Chemistry is crucial for building resilience in society and the environment. Its contributions are seen in areas like food, health, economic, and environmental security. Chemistry helps transform matter in ways that support human security and sustainability. To strengthen its impact, the field must adopt integrative approaches, rethink industrial practices, and engage more with society and policymakers . Integrating real-world problems into chemistry education, such as climate change and public health, makes learning more relevant and prepares students to tackle global challenges .
Challenges in Chemistry Education: Concept Formation and Misconceptions
Chemistry is often perceived as a difficult subject because many concepts are abstract and not directly observable. Students struggle to understand ideas like elements, compounds, and molecular structures, especially when introduced to multiple levels of thought (macroscopic, submicroscopic, and symbolic) at once. This can lead to misconceptions. A gradual, psychologically informed approach to teaching—focusing on concept development and effective use of laboratory work—can help students build a stronger understanding Johnstone2000Da Silva Freire2019.
Encouraging Student Engagement and Career Choices in Chemistry
Many students and parents view chemistry as less important than other sciences, and concerns about job prospects and safety risks can discourage students from pursuing it. To address this, experts suggest making chemistry education more engaging by connecting it to real-world applications, improving teaching methods, and highlighting the value of chemistry in various careers. Task-oriented self-efficacy, or students’ belief in their ability to succeed in chemistry tasks, is a key factor in choosing chemistry as a major or career. Women and minorities show different trends in choosing chemistry, with women more likely to pursue it at both high school and university levels Zhao2022Avargil2020.
The Impact of Technology and Indigenous Knowledge in Chemistry Learning
Recent advances show that large language models (LLMs) can effectively solve chemistry problems and support teaching and research, especially when used with good practices and prompt engineering. This technology is expected to have a significant impact on chemistry education and research . Additionally, incorporating indigenous knowledge into chemistry teaching can improve students’ metacognitive skills and make learning more meaningful and accessible, especially in diverse educational settings .
Reproducibility and Open Science in Chemistry Research
Reproducibility is a core value in chemistry, supported by reliable experimental methods. However, pressures to publish can sometimes lead to non-reproducible results. The adoption of open science practices, such as data sharing and open access, is helping to improve transparency and reproducibility in chemistry research .
Conclusion
Chemistry’s central role in science and society depends on how it is taught and practiced. Emphasizing systems thinking, real-world relevance, and inclusive teaching strategies can make chemistry more accessible and engaging. Integrating technology, indigenous knowledge, and open science practices further strengthens the field, ensuring that chemistry continues to address global challenges and inspire future generations.
