Practical work (travaux pratiques) refers to hands-on activities that engage students directly with scientific materials, equipment, and phenomena. Its main purpose is to enhance students’ experimental abilities, strengthen their grasp of theory through real-life application, and foster scientific inquiry and critical thinking.
Examples of practical work include lab experiments (o level science practical), fieldwork, demonstrations, and project-based learning—designed to give students concrete experiences that complement their theoretical studies.

What Is Practical Work?
Practical work, sometimes called travaux pratique or practical class, involves students performing tasks where they observe or manipulate objects to build understanding. This aligns with the idea of practical skills abilities gained through direct experience rather than just theory.
As defined by Millar (2009) and National Strategies (2008), practical work allows pupils to have direct, hands-on contact with the phenomena they study. In fact, a popular saying from SCORE (2008) puts it simply: “Science without practical work is like swimming without water.”
Core Elements of Practical Work
SCORE (2008) categorizes practical work into three groups:
Core Activities:
Hands-on tasks such as investigations, laboratory procedures, and fieldwork, which build practical skills and deepen scientific understanding.
Complementary Activities:
Presentations, role play, modeling, simulations, science visits, and discussions that enrich learning but are not central to practical science.
The Purpose and Importance of Practical Work
The goal of practical work is to actively involve students, bridging abstract theory and tangible experience. This practical approach is vital for effective learning, emphasizing the difference between practical and purely useful knowledge. It shows the practical importance of hands-on science in education.
Benefits of Practical Work for Students
Enhanced Learning: Practical activities help students visualize complex scientific concepts, reinforcing understanding through experience. Edgar Dale’s Cone of Experience highlights that practical work leads to meaningful and lasting learning.
Increased Motivation: Engaging in practical science boosts student interest and enthusiasm, promoting better information retention.
Skills Acquisition: Beyond content knowledge, practical work develops transferable skills crucial for future careers. Knowing what is a practical skill is key to appreciating this benefit.
Challenges and Considerations
Despite its advantages, practical work has some challenges:
Potential Confusion:
Practical tasks can sometimes confuse students, especially when abstract concepts cannot be observed directly. This raises questions about the meaning of practical in scientific contexts.
Possible Demotivation:
Not all students enjoy practical work; research shows boys tend to engage more enthusiastically than girls, potentially affecting participation.
Lack of Engagement:
Group practicals may not always improve communication, as dominant students might overshadow others.
Practical Work in Science Education
The effectiveness of practical work remains a debated topic. Jean Piaget’s constructivist theory supports the idea that knowledge builds through active experience, making practical work essential. Yet, studies provide mixed results, suggesting that how practical classes and lab practicals are designed matters significantly.
Conclusion
Understanding practical work (travaux pratiques) and what practical means in education is crucial for improving science teaching.
Whether referred to as practical science, lab practical, or practical professional training, hands-on activities remain a cornerstone of scientific learning and skill development, highlighting their irreplaceable role in education.
Frequently Asked Questions (FAQ) About Practical Work
Q1: What is practical work (travaux pratiques)?
Practical work involves hands-on activities where students directly interact with scientific materials and phenomena. It helps develop practical skills by applying theory to real-life situations.
Q2: What is a practical skill?
A practical skill is an ability gained through doing tasks or experiments, not just by learning theory. It includes skills like conducting experiments, using lab equipment, and problem-solving in real scenarios.
Q3: What is lab practical or science practical?
Lab practicals are sessions where students perform experiments in a lab setting to understand scientific concepts firsthand. They are common in O Level science exams and other curricula.
Q4: How is practical work different from theoretical learning?
Practical work focuses on doing and experiencing, while theoretical learning involves understanding concepts through reading or lectures. Both complement each other for effective education.
Q5: Why is practical work important in science education?
It bridges the gap between abstract theories and real-world applications, making scientific knowledge more tangible and understandable.
Q6: What are some examples of practical work?
Examples include lab experiments, field observations, demonstrations, group investigations, and project-based learning.
Q7: What does practical mean in a sentence?
For example, “The practical use of scientific knowledge helps students solve real-world problems.”
Q8: What are practicals in science?
Practicals are experimental activities that allow students to test hypotheses and observe phenomena, forming a core part of science education.
Q9: How can practical work affect student motivation?
Hands-on activities often increase interest and enthusiasm, making learning more engaging and memorable.
Q10: What challenges exist with practical work?
Some students may find practical work confusing or less engaging, especially if experiments don’t go as planned or group dynamics hinder participation.
