In the IELTS Speaking test, candidates often encounter questions that require them to describe complex situations or ideas. One such topic is “describe a time when you had to explain a complex idea.” This subject has appeared frequently in past IELTS exams and is likely to remain relevant in future tests. Let’s explore how to effectively tackle this topic and achieve a high band score.

Part 1: Introduction and Interview

In this section, the examiner may ask general questions related to explaining ideas. Here’s a sample question with a suggested answer:

Examiner: Do you find it easy to explain things to others?

Band 7-8 Answer: “Well, it largely depends on the topic and the audience. When I’m discussing subjects I’m passionate about, like technology or science, I find it quite enjoyable to break down complex concepts into simpler terms. However, I must admit that explaining intricate ideas to people unfamiliar with the subject can be challenging at times. I’ve learned that using analogies and real-life examples often helps make abstract concepts more relatable and easier to grasp.”

Part 2: Long Turn

Cue Card

Describe a time when you had to explain a complex idea to someone.

You should say:

• What the idea was
• Who you explained it to
• How you explained it
• And explain why it was difficult to explain

Band 6-7 Sample Answer:

“I’d like to talk about a time when I had to explain the concept of blockchain technology to my grandmother. She’s always been curious about my work in IT, but this particular topic was quite challenging to break down.

Blockchain is essentially a decentralized digital ledger that records transactions across many computers. It’s the technology behind cryptocurrencies like Bitcoin. The difficulty lay in explaining this to someone who isn’t very tech-savvy.

I started by using an analogy she could relate to – a recipe book shared among friends. I explained that instead of one person keeping the book, everyone has a copy, and when a new recipe is added, all copies are updated simultaneously. This way, no single person can alter the recipes without everyone knowing.

To make it more tangible, I used some props like small notebooks to represent computers and colored sticky notes for transactions. I demonstrated how each ‘computer’ would verify and add new information, creating a chain of data that’s nearly impossible to tamper with.

The challenging part was simplifying the technical aspects without losing the essence of the concept. I had to constantly gauge her understanding and adjust my explanation accordingly. It took patience and creativity, but eventually, she grasped the basic idea.

This experience taught me the importance of tailoring complex information to the listener’s background and using relatable analogies to bridge the knowledge gap.”

Band 8-9 Sample Answer:

“I’d like to recount an instance when I had to elucidate the intricate concept of quantum computing to a group of high school students during a career day presentation. Quantum computing, a field at the intersection of quantum physics and computer science, is notoriously difficult to comprehend, even for many adults in the tech industry.

The crux of quantum computing lies in its utilization of quantum mechanical phenomena, such as superposition and entanglement, to perform computations. These principles deviate significantly from classical computing paradigms, making them particularly challenging to convey to an audience unfamiliar with quantum physics.

To tackle this complex subject, I employed a multi-faceted approach. I began by drawing parallels between classical bits and qubits, using visual aids to illustrate the concept of superposition. For instance, I used a coin analogy, explaining how a classical bit is like a coin showing either heads or tails, while a qubit can be in a state of ‘both’ simultaneously until observed.

To demonstrate entanglement, I utilized a pair of gloves as props. I explained how separating entangled qubits is akin to putting one glove in each of two sealed boxes and sending them to opposite ends of the universe – the moment you open one box and see a left-hand glove, you instantly know the other box contains a right-hand glove, regardless of the distance between them.

The most challenging aspect was conveying the practical implications and potential applications of quantum computing without oversimplifying the underlying science. I had to strike a delicate balance between maintaining scientific accuracy and ensuring the information was digestible for the students.

I incorporated interactive elements, such as thought experiments and simplified coding exercises, to engage the students and make the abstract concepts more tangible. This approach not only facilitated better understanding but also sparked curiosity and interest in the field.

This experience underscored the importance of adapting complex scientific concepts to the audience’s level of understanding, using relatable analogies, and fostering an interactive learning environment. It also reinforced my belief in the power of effective communication in bridging the gap between cutting-edge technology and public understanding.”

Describe a time when you helped a friend through a difficult situation can be another challenging topic that requires clear explanation skills similar to those needed for describing complex ideas.

Follow-up Questions

Examiner: What strategies do you find most effective when explaining difficult concepts?

Band 7-8 Answer: “In my experience, using analogies and real-world examples is incredibly effective. Breaking down complex ideas into smaller, more manageable parts also helps. Additionally, I find that visual aids, such as diagrams or props, can significantly enhance understanding, especially for more abstract concepts.”

Band 8-9 Answer: “I’ve found that a multi-pronged approach tends to yield the best results. Firstly, I assess the listener’s background knowledge and tailor my explanation accordingly. Then, I employ a combination of techniques: using relatable analogies, creating visual representations, and encouraging interactive engagement. I also find it crucial to regularly check for understanding and adjust my explanation in real-time. Furthermore, contextualizing the concept by discussing its real-world applications often helps solidify comprehension and maintain interest.”

Part 3: Two-way Discussion

Examiner: In your opinion, what makes some ideas more difficult to explain than others?

Band 6-7 Answer: “I think ideas can be hard to explain when they’re very technical or abstract. Sometimes, the person you’re explaining to might not have much background knowledge, which makes it tougher. Also, if an idea goes against common sense or what people usually believe, it can be harder to get the point across.”

Band 8-9 Answer: “The complexity of an idea’s explanation often hinges on several factors. Firstly, the degree of abstraction plays a crucial role – concepts that are highly theoretical or divorced from everyday experience naturally pose greater challenges. Secondly, the disparity between the explainer’s and the listener’s knowledge base can significantly impact comprehension. A wide gap necessitates more foundational explanation, which can be time-consuming and potentially overwhelming.

Moreover, ideas that challenge established paradigms or intuitive understanding are inherently more difficult to convey. This is because they require not only the transmission of new information but also the deconstruction of existing beliefs or mental models. Lastly, the interdisciplinary nature of certain concepts can add layers of complexity, as they may require understanding across multiple domains of knowledge.”

Examiner: How has technology changed the way we explain and understand complex ideas?

Band 7-8 Answer: “Technology has revolutionized how we explain and understand complex ideas. With tools like interactive simulations and 3D modeling, we can now visualize abstract concepts. Online platforms and educational apps make it easier to access explanations of difficult topics. Social media and video-sharing sites allow experts to reach wider audiences, simplifying complex subjects for the general public.”

Band 8-9 Answer: “Technology has fundamentally transformed our approach to explaining and comprehending complex ideas. The advent of data visualization tools and interactive simulations has made abstract concepts tangible and explorable. This shift from passive consumption to active engagement significantly enhances understanding and retention.

Artificial Intelligence and machine learning algorithms are now capable of personalizing explanations, adapting to individual learning styles and prior knowledge bases. This tailored approach optimizes the learning process, making complex ideas more accessible to diverse audiences.

Furthermore, the democratization of information through online platforms has fostered a culture of collaborative learning. Concepts can now be dissected and discussed in real-time by global communities, leading to richer, more nuanced understandings. Virtual and augmented reality technologies are pushing the boundaries even further, allowing for immersive experiences that can make abstract ideas feel almost tactile.

However, it’s worth noting that while technology has expanded our explanatory toolkit, it has also increased the complexity of ideas we’re trying to understand. This creates a dynamic interplay between technological advancement and conceptual complexity, continually challenging us to innovate in our explanatory methods.”
