Transforming chemistry education by connecting abstract concepts to real-world applications
Picture a typical secondary school chemistry classroom. Students memorize the periodic table, balance chemical equations, and perhaps watch as a teacher demonstrates a reaction. For many, the subject feels like a collection of abstract concepts and disconnected facts. This widespread sentiment that chemistry is difficult and irrelevant to everyday life has long been a challenge for educators worldwide 1 .
Students often struggle to see the connection between the formulas in their textbooks and the world beyond the classroom, leading to disengagement and a perception that chemistry is merely a hurdle to overcome rather than a fascinating science central to modern life.
This article explores an innovative educational approach—Activity Theory—that is successfully bridging this gap. By reimagining how chemistry is taught, this method is transforming classrooms into dynamic environments where students discover the profound relevance of chemistry in their personal lives, future careers, and roles as informed citizens.

Activity Theory is a framework originating from the sociocultural tradition of psychology. In essence, it provides a model for understanding human behavior and learning within their broader social and cultural contexts. Unlike traditional teaching methods that can create a divide between science and society, Activity Theory offers a model in which the two are intrinsically linked 2 .
When applied to chemistry education, this means designing learning activities that are not just about knowing chemistry, but about using chemistry as a tool to achieve meaningful, real-world goals. The theory emphasizes that students learn best when they are actively engaged in a purposeful process, collaborating with others, and using tools (both conceptual and physical) to achieve an outcome that they find genuinely significant.
Activity Theory promotes a classroom as a community where knowledge is constructed through shared, relevant activities rather than passively received.
Students as passive recipients of information through lectures and textbook reading.
Students as active participants in knowledge construction through meaningful tasks.
To understand how Activity Theory works in practice, it's helpful to view it through the lens of educational relevance. Research identifies three key dimensions that make learning feel relevant to students 3 :
Chemistry connects to a student's personal interests and daily life. Learning offers useful skills for navigating the world and developing intellectual curiosity.
The skills and knowledge are clearly linked to future academic pursuits, entrance exams, or potential career paths.
Students understand the connection between chemistry and societal issues, equipping them to act as responsible, scientifically-literate citizens.
Activity Theory is uniquely powerful because it can address all three levels simultaneously through well-designed classroom activities.
A compelling example of this approach comes from an action research project conducted with 14-15-year-old students in Karachi, Pakistan 1 . The researcher noted that chemistry courses were often "drowned in a sea of dull and abstract" concepts, causing even capable students to lose sight of the underlying principles.
The study set out to transform the teaching of industrial chemistry concepts using the Activity Theory approach. The goal was not just to teach facts, but to present "Chemistry as a relevant subject to the student's person, profession and society" 1 .

Industrial Chemistry Concepts
The project was conducted in three iterative cycles, each involving planning, action, observation, and reflection. Here is the methodology they employed:
The first step was to develop a curriculum that framed industrial chemistry concepts around contextual needs and real-world applications, moving away from non-contextual vocabulary and rote learning 1 .
The teacher created an engaging learning environment using multimedia tools, including video clips and factory models. These tools helped demystify industrial processes and provided a visual and concrete anchor for abstract concepts 1 .
Various teaching strategies and classroom organizations were used to promote active learning. Students were engaged in collaborative tasks and problem-solving activities that mirrored real-world chemical applications 1 .
Data was collected through interviews, classroom observations, and student reflections. This feedback was used to refine and improve the activity in subsequent cycles, ensuring it effectively met its goals 1 .
| Aspect | Traditional Approach | Activity Theory Approach |
|---|---|---|
| Focus | Memorizing facts and formulas | Understanding concepts in real-world contexts |
| Content | Non-contextual vocabulary and process skills | Curriculum designed around contextual needs 1 |
| Teaching Tools | Textbook, chalkboard | Video clips, factory models, collaborative activities 1 |
| Student Role | Passive recipient of information | Active participant in a learning community 1 |
| Primary Goal | Scoring high on exams | Developing transferable knowledge, skills, and attitudes for daily life 1 |
The results of the study were clear. By integrating the Activity Theory model, the researcher successfully created relevance in teaching industrial chemistry 1 . The approach helped bridge the gap between the abstract concepts found in textbooks and the practical, contextual needs of the students' world.
While the search results do not provide specific quantitative data, the study concluded that the methodology proved effective in making the subject matter more relevant and engaging for the students involved. This hands-on, context-rich approach helped students see the purpose behind the chemistry they were learning, moving them from passive memorizers to active participants in their scientific education.

Implementing Activity Theory requires a shift in the "tools" used in the classroom. This toolkit includes both conceptual frameworks and physical materials that help mediate learning.
Frameworks lessons around real-life situations (e.g., environmental issues, industrial processes) that students can relate to 3 .
Uses current scientific innovations (e.g., ionic liquids, green chemistry) to show how chemical knowledge is generated and applied today 3 .
Provides a safe, accessible platform for students to conduct experiments that might be too dangerous, expensive, or complex for a school lab 4 .
Offers visual and concrete representations of abstract processes (e.g., factory operations, molecular interactions), making them easier to understand 1 .
The implications of using Activity Theory extend far beyond a single lesson. This approach aligns with broader educational movements, such as Experiential Learning, which emphasizes hands-on engagement and active knowledge construction 4 . Research shows that such methods motivate student interest, enhance concept comprehension, and build critical thinking abilities 4 .
By making chemistry relevant, we prepare a new generation of scientifically literate citizens. They are better equipped to understand complex issues like sustainability, climate change, and public health, and are more likely to pursue careers in science, technology, engineering, and mathematics (STEM) fields.
The problem of chemistry's perceived irrelevance in secondary schools is not insurmountable. As the case study and theoretical research demonstrate, Activity Theory provides a powerful framework for change. By moving instruction from a list of facts to be memorized to a set of meaningful activities to be experienced, educators can show students that chemistry is not just a subject—it's a vital tool for understanding and improving the world around us.
The ultimate goal is to transform the classroom from a place where students ask, "Why do I need to know this?" into a space where they can excitedly declare, "So that's how it works!"
