IELTS Writing Task 1 question

The diagram below shows how a mechanical arm works, and how the joints that make up the arm function in the same way as those in a human arm. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Student answer (Band 5.0)

In this diagram below is showing how a mechanical arm works. The key aspects elaborates its how the joints work as same the human arm. The gripper mainly built to sense the items when same like we use an arm for. The wirst is use for the grip when we take up the thing and pivot enales to rotate. Just like the human elbow also have in this device also. By these features we can done those tasks by simply we do from the real one hand. However, the computer is also installed in this device to control of device. It made the device more functionally good. In comparison this device to others, I belives its a good one because in real world some tasks done by such kind of , can make a work flow more convenient rather than just done by all workers also productivity will also increase.

AI examiner evaluation

Task Achievement / Task Response — Band 5.0

The response attempts to describe the mechanical arm but fails to provide a clear, objective summary of the visual information. Instead of focusing on the specific components and their functions as shown in the diagram, the response drifts into subjective commentary about productivity and the 'real world'. The description of the arm's features is fragmented and lacks the necessary detail to fully explain the mechanism. Key parts of the diagram, such as the specific joints or the comparison to the human arm, are mentioned but not clearly explained or contrasted. To improve, focus strictly on reporting the data presented in the image rather than offering personal opinions.

Coherence and Cohesion — Band 5.0

The response lacks a logical structure. It is written as a single paragraph, which makes it difficult to follow the progression of ideas. There is a lack of cohesive devices to link sentences, and the transition between describing the device and discussing its benefits is abrupt. The use of referencing is often unclear, such as in the phrase 'by these features we can done those tasks', which lacks a clear antecedent. To improve, use clear paragraphing to separate the description of the device from any concluding remarks and employ a wider range of linking words like 'furthermore', 'consequently', or 'in contrast' to guide the reader.

Lexical Resource — Band 5.0

The vocabulary is limited and often inaccurate, which hinders the clarity of the description. Phrases like 'functionally good' and 'take up the thing' are imprecise and informal. There are also issues with word formation, such as 'enales' (likely a typo for enables) and 'belives'. The range of vocabulary is insufficient to describe technical or mechanical processes effectively. To reach a higher band, you should focus on using more precise, topic-specific terminology related to mechanics and engineering, and ensure that your word choices are appropriate for an academic report.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors that often impede communication. There are significant issues with subject-verb agreement ('The key aspects elaborates', 'the wirst is use'), sentence construction ('In this diagram below is showing'), and tense usage. Many sentences are poorly formed, making them difficult to parse. The range of structures is limited, relying mostly on simple sentences with errors in basic syntax. To improve, focus on mastering basic sentence structures, ensuring subject-verb agreement, and proofreading for common errors like missing articles or incorrect verb forms.
