Teaching Students About Microtubules


Microtubules are an essential component of the cell’s cytoskeleton, playing a significant role in determining the cell’s overall shape and structure. They are also responsible for vital functions such as cell division and intracellular transport. Teaching students about microtubules can pique their curiosity and interest in cell biology, while fostering critical thinking skills that they can apply to other scientific disciplines.

This article will guide educators through various strategies for effectively teaching students about microtubules, including identifying key concepts, exploring engaging teaching methods, and providing relevant resources to supplement classroom instruction.

Key Concepts

Before delving into teaching strategies, it is crucial to outline the key concepts students need to understand regarding microtubules. These include:

1. Structure: Microtubules are composed of tubulin protein subunits that assemble into long, filamentous structures.

2. Function: Microtubules play crucial roles in maintaining cell shape, providing structural support, enabling cell motility, and facilitating intracellular transport.

3. Dynamic Instability: Microtubules constantly undergo a process of growing and shrinking, making them “dynamic” structures within the cell.

4. Role in Cell Division: During cell division (mitosis and meiosis), microtubules form the mitotic spindle that helps separate chromosomes and distribute them to daughter cells.

Teaching Strategies

Given these essential concepts, several teaching strategies can be employed to ensure students have a solid understanding of microtubules:

1. Visualization tools: Incorporate microscopy images or videos showcasing microtubule structures and their associated cellular processes to help students better grasp abstract concepts.

2. Hands-on activities: Engage students in hands-on activities to model microtubule dynamics using materials like pipe cleaners or straws for the purpose of illustrating growth and shrinkage.

3. Analogies: Establish connections between microtubules and real-world examples, such as comparing a cell’s cytoskeleton to the framework of a building or relating dynamic instability to the growth and collapse of a cityscape.

4. Group discussions: Organize group discussions to promote critical thinking and foster a deeper understanding of microtubule intricacies.


Supplementing classroom instruction with relevant resources can further enhance student learning. Some useful resources include:

1. Online encyclopedias and databases: Websites like Encyclopedia.com and RCSB PDB offer detailed information about microtubules that can be tailored to suit various educational levels.

2. Educational videos: Animated videos on platforms such as YouTube or TED-Ed can provide visually engaging explanations of microtubule structure and function.

3. Research articles: Introduce students to peer-reviewed research articles on microtubules to inspire curiosity and demonstrate the ongoing nature of scientific discovery.


Teaching students about microtubules opens up a fascinating world of cellular processes that can be both engaging and intellectually stimulating. By utilizing comprehensive teaching strategies that cover key concepts, encourage active participation, and draw from diverse resources, educators can effectively convey the significance of microtubules in cell biology and inspire future generations of scientists.
