Utilizing Interactive 3D Models To Teach Cellular Physiology in Online Courses

June 2, 2023

The rapid advancement of technology and the increasing popularity of online courses have opened up new possibilities for innovative teaching methods in various fields, including cellular physiology. One emerging approach is utilizing interactive 3D (three-dimensional) models to enhance students’ understanding of complex cellular processes. 

Interactive 3D models are engaging and allow students to study cellular structures more actively and realistically. They’re an innovative approach to teaching cellular physiology online, and many of these digital tools can improve knowledge of complex cellular structures and processes.

Cellular Physiology and Its Complexity

Cellular physiology, or cell physiology, is the study of a cell’s structure and functions, which is essential in understanding living organisms and various diseases. Cellular physiology plays a major role in the following:

  1. Basis of life: Understanding cell functions and interactions helps us comprehend the complex biological systems in living organisms.
  2. Medical applications: Cellular physiology provides insights into the causes and progression of diseases, which can help develop treatments to improve health.
  3. Biotechnology and genetic engineering: Biotechnology applies cell physiology to modify crops, clone plants and animals, produce quality food at lower costs, develop medicine, and create organs for transplant purposes.
  4. Drug discovery: Researchers study drug interactions and cellular components to evaluate their efficiency and safety, which helps design better pharmaceuticals and minimize potential side effects.

Challenges of Teaching Cellular Physiology Online

Teaching cellular physiology online poses several challenges:

  1. Complex subject material: Online learning may provide less room for interaction and engagement between educators and learners than in traditional classroom settings, making it more challenging for students to understand the subject matter.
  2. Limited access to laboratory experiences: Students have limited access to laboratory experiments and cannot observe cellular processes firsthand.
  3. Lack of engagement and motivation: Online learning can sometimes lead to reduced student engagement and attention due to the absence of face-to-face interaction with instructors and peers. 
  4. Technical issues: Connectivity problems, inadequate hardware, or software limitations can disrupt the learning process for students and instructors, compromising the quality of education.

The Power of 3D Models in Health Science Education

3D models have proven invaluable tools for visualizing biological structures and processes in health science education. Here are some of the benefits they offer.

Enhanced Understanding of Complex Structures

3D models enhance visuospatial abilities (one’s ability to identify visual and spatial relationships in objects), helping users differentiate elements within a structure and making it easier to understand their organization and function.

For example, researchers use 3D models to study and visualize protein structures and design drugs targeting specific proteins involved in diseases.

Virtual Experiments 

3D models remove the need for physical lab experiments and provide a platform for virtual experiments. Educators can use controlled spaces to simulate practical experiments virtually, giving students a more realistic learning experience.

Some biological experiments that are difficult to observe directly, like those involving neural networks, use 3D models for better outcomes. 

Better Understanding of Dynamic Processes 

Biological processes often involve much movement and interaction between different systems. 3D models can use animations to illustrate these dynamic processes, providing a clearer understanding of how molecules interact and function over time.

Cellular respiration is an excellent example of a dynamic process. Using 3D models to visualize the process, such as the electron transport chain in the mitochondria, helps students understand the flow of electrons and protons and the synthesis of adenosine triphosphate.

Interactive 3D Models for Cellular Physiology

Interactive 3D models allow students to better visualize cell structures and their functions, making complex concepts more accessible and easily understood.

Students can use interactive 3D models to explore the detailed structure of cells. By rotating, zooming, and dissecting virtual cells, students can better understand the spatial relationships between various structures and learn how they’re organized within the cell.

Implementing Interactive 3D Models in Online Courses

Technology has become integral to many areas of study, and cellular physiology is no exception. Here are some ways educators can smoothly integrate 3D models into online lessons and assignments: 

  • Introduce the 3D concept: Properly introduce the program so that students can approach the 3D model with background information and clear objectives. You can start with the less complex versions to give your students time to familiarize themselves with the software.
  • Use instructions and demos: Provide live demos or prerecorded videos showing how students can use the model to learn different aspects of cellular physiology. Include instructions on what students should focus on and examine. 
  • Integrate with other learning materials: Combine 3D models with additional learning resources like textbooks to help students understand and connect theoretical concepts with visual representations. Use the 3D modeling software to complement traditional teaching other than fully replace it.
  • Assignments: Allow students to explore the software independently. Use assignments and quizzes with the 3D models to assess your students’ progress. 

Choosing the best 3D model software can be daunting, and you may need to find the most suitable one for your online courses. Here are some practical considerations for choosing 3D modeling Software:

  • Define your objectives: What would you like to achieve at the end of the online course? Who is your target audience? Clearly defined objectives can help you start narrowing down your options.
  • Check the software features: Double-checking the features of each 3D modeling Software will save you a lot of time and resources. Look at the software’s user-friendliness, quality of the visuals, system compatibility, interactivity, and customization options.
  • Assess the cost and support: Some 3D models are free but are notably less useful than paid versions. Compare the costs and the benefits. Also, consider 3D software with support options like tutorials and user guides to get the most out of it.
  • Test the software: Run a trial test before fully committing to 3D modeling software. Try using free versions or demos to familiarize yourself with it and assess if it meets your intended needs.

Case Study 2: Coursera

Coursera has long used online technology to educate learners worldwide. It offers a wide range of courses, including cell physiology with 3D models.

Case Study 3: Massachusetts Institute of Technology — MITx Biology

MITx Biology is a successful online learning platform developed by the Massachusetts Institute of Technology. It offers massive open online courses, including cellular physiology courses that incorporate interactive 3D models.

Potential Challenges of Using 3D Models and Possible Solutions

While 3D models have many benefits, they aren’t perfect. Here are some potential challenges and possible solutions.

Technical Issues

Here are three common technical challenges of using 3D models.

  • Hardware issues: 3D models are usually associated with powerful processors and graphic capabilities, which may challenge some students. To solve this issue, seek alternatives like computer labs or cloud-based platforms to accommodate all students.
  • Software issues: Some 3D models might not be compatible with your devices, which can inconvenience you and your students. Consider using web-based software that might not require installation.
  • Connectivity: Teaching 3D models requires a reliable network connection, a steady power supply, and access to the internet, which may not be accessible to all learners and institutions. Foster collaborations with other educators, students, and institutions to share resources and alternative power and internet sources.

Learning Curve

Some learners take time to familiarize themselves with the 3D models, slowing the learning process. Others may learn faster. Consider giving your students time to learn at their own pace or start with less complex tasks so that no one is left behind.


Learners with visual impairments might struggle to use the 3D models. Use audiovisual models to enhance inclusivity.
