Task 4: Integrated Speaking Task – Academic Lecture

Task 4 is the final part of the TOEFL iBT Speaking section and is designed to test your ability to understand and summarize academic content. In this task, you’ll listen to a lecture on an academic subject, typically in areas like science, history, or social studies. Your job is to summarize the main points of the lecture and explain them clearly.

Task structure:

1. Listening component:

You’ll listen to an academic lecture that lasts about 90-120 seconds. The lecture typically presents a concept, theory, or event, along with explanations or examples. No reading material is provided for this task.

2. Speaking component:

After the lecture, you’ll have 20 seconds to prepare your response and 60 seconds to speak. Your task is to summarize the key points from the lecture, showing your ability to understand and explain the information in your own words.

What the Task evaluates:

Comprehension: How well you understand the lecture and its key ideas.
Delivery: The clarity, fluency, and naturalness of your spoken response.
Organization: How well you organize and structure your summary.
Accuracy: How accurately you explain the key points from the lecture.

Example 1

You will listen to part of a lecture in a marketing class. Listen carefully, and take notes as needed.

Direction

Give yourself 20 seconds to respond to the following question. Then, you have 60 seconds to speak.

Question:

Summarize the lecture, explaining the two marketing strategies discussed by the professor and how each strategy helps companies compete in the marketplace.

Sample answer

In the lecture, the professor explains two different marketing strategies that companies use: product differentiation and market segmentation. Product differentiation is when companies highlight unique features of their product to make it stand out from competitors. For example, in the case of smartphones, companies might focus on specific features like having a better camera or longer battery life, which allows them to charge higher prices because consumers see these features as more valuable.

The second strategy is market segmentation, where companies divide the market into different groups based on characteristics like age or lifestyle. Instead of marketing to everyone, they tailor their approach to target specific groups. For instance, a sports shoe company might advertise one type of shoe to professional athletes, emphasizing performance, while promoting a different, more affordable shoe to casual runners, focusing on comfort. Both strategies help companies compete by either standing out through unique features or by appealing to specific groups of consumers.

Example 2

You will listen to part of a lecture in a biology class. Listen carefully, and take notes as needed.

Direction

Give yourself 20 seconds to respond to the following question. Then, you have 60 seconds to speak.

Question

Using points and examples from the talk, describe two adaptations that help Arctic animals survive in their environment.

Sample answer

In the lecture, the professor talks about two different adaptations that help Arctic animals survive. First, the Arctic fox has thick fur that helps it stay warm in freezing temperatures. What’s really interesting is that its fur changes color depending on the season. In winter, the fur is white to blend in with the snow, and in summer, it turns brown or gray to match the rocky environment. This helps the Arctic fox stay hidden from predators and prey all year round.

Next, the polar bear has a thick layer of blubber under its skin that insulates it from the cold. This, combined with its thick fur, helps the polar bear stay warm even in icy waters. Polar bears are also excellent swimmers, which allows them to travel long distances to hunt for seals, especially when the ice melts in the summer. These adaptations make both the Arctic fox and polar bear well-equipped to survive in such extreme conditions.

Tips for success in TOEFL iBT Speaking Part 4

1. Take efficient notes

The lecture will contain examples and explanations. Focus on the main concepts and supporting details rather than trying to write down everything. You don’t need full sentences—just key words and phrases.

You can divide your notes into two parts – one for each “thing” the lecturer talks about. So, from the example above, you can divide it into “product differentiation and market segmentation” for the first example and “arctic fox and polar bear” for the second example. Then, write the explanation about each of the two things under the appropriate heading. So, for example, you can write “thick fur” and “color-changing fur” under “arctic fox”.

We also highly recommend using shorthands. For instance, “temp” for temperature and “PB” for Polar Bear.

2. Use a clear structure

Organize your response with a simple and effective structure, such as:

Introduction: Briefly introduce the topic or concept from the lecture.
Explanation 1: Summarize the first example or concept with supporting details
Explanation 2: Summarize the second example or concept with supporting details.
Conclusion: Briefly summarize how the two examples relate to the topic

3. Use transition words

Transition words and phrases help your answer sound more organized and smooth. Some useful transitions for Task 4 include:

Introducing examples: “For example,” “One example is,” “The first adaptation is,” “Another adaptation is”
Connecting ideas: “Additionally,” “Also,” “Moreover,” “Similarly”
Summarizing: “In conclusion,” “Overall,” “To sum up”

4. Paraphrase instead of repeating

Instead of repeating exactly what the professor said, try to paraphrase the information. This shows you understand the material and can explain it in your own words.

5. Manage your time effectively

Use your 20-second preparation time wisely. During this time, quickly review your notes and decide which key points you’ll include in your answer. You don’t have time to overthink—just focus on organizing your thoughts.

Next, practice the 60-second time frame. Record yourself summarizing lectures and time your responses to get used to delivering within the time limit. Make sure your answer doesn’t feel rushed or incomplete.

6. Stay calm and focus on the main ideas

Don’t worry if you miss a small detail. The graders are looking for your ability to summarize the main points and connect the ideas logically. Focus on delivering a confident, coherent summary rather than trying to remember every single point.

7. Practice listening to lectures

Since Task 4 relies heavily on your listening skills, practice listening to academic lectures or TED Talks on topics like biology, history, or psychology. After listening, try to summarize the main ideas to build your skills in identifying key points.
