From lab to screen with Virtual Practicals for the Digital Age

With more and more online educational tools being developed, both paid and open source, our RALDE team saw the opportunity to investigate how teachers and educators can introduce virtual practicals into their curriculum. With these digital practicals offering such a versatile and innovative approach, it could be the next step of evolution our educational methods need.

Where we started

As a team dedicated to rethinking educational experiences, we recognized the potential of these ‘virtual practicals’ to transform laboratory learning, especially during the challenging times of the COVID-19 pandemic. Initially, our move towards virtual labs was driven by the necessity to maintain practical, hands-on learning in an environment where traditional classroom labs were inaccessible. However, as we started developing our virtual practicals, focusing on the areas of cell cultures and rodent dissection, we discovered the broader advantages of this approach.

Virtual labs are not only a solution for times of crisis but also a forward-thinking educational tool that offers accessibility, safety, and efficiency, transcending the limitations of physical labs. Our journey into creating these virtual practicals from scratch gave us valuable insights and feedback into the feasibility of such endeavors for educators globally. We realized that what began as a pivot during a pandemic could well be a sustainable and versatile method for delivering practical science education in various contexts, far beyond our initial expectations.

Understanding the opportunities and drawbacks of using innovative techniques

As we navigate through this shift from traditional to digital laboratory experiences, it’s crucial to weigh the advantages and potential drawbacks. The following lists of pros and cons provide a comprehensive overview, helping educators, students, and institutions to understand the multifaceted impacts of virtual practicals. This balanced perspective aims to inform decision-making and guide the effective integration of virtual labs in educational settings.


1. Accessibility: Virtual labs are accessible to a wider range of students, including those in remote or resource-limited areas.

2. Cost-Effectiveness: They reduce the need for expensive lab equipment and materials, making practical education more affordable.

3. Safety: Eliminates risks associated with handling hazardous materials or conducting potentially dangerous experiments.

4. Flexibility: Students can access virtual labs at any time, allowing for self-paced learning and accommodating different learning styles.

5. Scalability: Virtual practicals can cater to a large number of students simultaneously, overcoming the space and resource constraints of physical labs.

6. Consistency in Experimentation: Ensures that all students experience the same standard of lab setup and conditions.

7. Interactive Learning: Enhanced interactivity and engagement through simulations that might not be feasible in a physical setting.

8. Data Collection and Analysis: Simplifies the process of collecting and analyzing data, often with built-in tools and software.

9. Environmental Friendly: Reduces the ecological footprint by eliminating the need for animals, chemicals and disposable lab equipment.


1. Lack of Hands-On Experience: Cannot fully replicate the tactile experience and manual dexterity skills developed in physical labs.

2. Technical Challenges: Dependence on technology can be a barrier, especially with poor internet connectivity or lack of digital devices.

3. Reduced Social Interaction: Misses out on the collaborative and social aspects of learning in a physical lab environment.

4. Limited Exposure to Real-Life Scenarios: May not fully prepare students for real-world lab situations, where unexpected outcomes can occur.

5. Simplification of Complex Processes: Some virtual labs might oversimplify experiments, not reflecting the true complexity of scientific work.

6. Learning Curve for Instructors: Teachers may require additional training and time to effectively incorporate virtual labs into their curriculum.

7. Evaluation Challenges: Assessing students’ practical skills and techniques can be more challenging in a virtual environment.

8. Technical Limitations: Some complex experiments might be too difficult to simulate realistically in a virtual setting. 

9. Potential for Reduced Engagement: Without the physical aspect of lab work, some students might find virtual labs less engaging or motivating


Throughout this project, our team wanted to have hands-on experience when it came to these virtual practicals. This evolved from two distinct virtual labs into a versatile, open-source platform.

Initially, we focused on creating individual virtual practicals in cell culture and rodent dissection. These were designed with specific learning goals in mind, ensuring that they not only complemented traditional lab experiences but also enriched students’ understanding before they even entered a physical lab.

The development of our rodent dissection tool was driven by a dual purpose: to offer a high-value educational experience and to significantly reduce the use of animals for educational purposes. This tool represents our commitment to ethical learning practices, preserving animal lives without compromising the quality of education.

As our project progressed, we recognized the potential for a broader application. We pivoted to creating an open-source platform that could host multiple practicals, a decision that opened up new possibilities for educators around the world. This platform, though currently a minimum viable product (MVP) due to developmental time constraints, lays the groundwork for a future where educators can develop and adapt their virtual practicals with ease. Unlike a single, baked-in practical, our platform offers flexibility and adaptability, allowing educators to tailor content to their specific teaching needs and objectives.

This development journey reflects our belief in continuous innovation and adaptation in education. By providing this open-source tool, we aim to empower educators to create bespoke virtual practicals, thereby broadening the scope and impact of practical science education in a rapidly changing world.

P.S. This might be the team you need

Building a successful virtual practical requires a collaborative effort from a diverse team, each bringing their own expertise to the table. We propose a team composition that includes one or two skilled developers, preferably with scientific background, who can bring the tool to life with their technical skillset. A scientist is crucial for ensuring the accuracy and educational value of the content, making the practicals relevant and effective. Additionally, a UX Designer plays a pivotal role in creating an intuitive and user-friendly interface, ensuring that the tool is accessible and engaging for students. Together, this team can create a virtual practical that is not only true to the learning objectives, but also captivates the student’s interest. This combination of skills and perspectives is what makes a team well-equipped to venture into the creation of impactful and effective virtual practicals.
