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 5.5)

As we can see i the diagram the arm is controlled by a computer for precision control. It consist of 3 main motors in its shoulder that raises and lowers the arm, another one in it elbow that allows movment and flexibility and the last one is near the wrist that allows gripper to rotate. It is mounted on a solid base and has a pivot that allows the arm to rotate, and at the end of the arm it has grippers that consist of built-in sensors that can feel the surface of the object that it picking and how much force is needed. You can say just like a real arm it has a shoulder, elbow and a wrist and it perfectaly replicate how a real human hands works, But it is without the human error and has a god like precision to do task that might be difficult for a human to do with ease.

AI examiner evaluation

Task Achievement / Task Response — Band 5.5

The response covers the main features of the mechanical arm, identifying the motors, joints, and sensors. However, the report lacks a clear overview or summary of the process, which is essential for Task 1. The description is somewhat informal and relies on subjective commentary, such as 'god like precision,' rather than objective reporting of the visual data. To improve, focus on describing the mechanical components and their functions more systematically, ensuring that the comparison between the mechanical and human arm is presented as a factual observation rather than an opinion. The response would benefit from a more structured approach to presenting the technical details.

Coherence and Cohesion — Band 5.0

The response is written as a single paragraph, which hinders the logical flow and organization of the information. While there is a basic attempt to sequence the description from the base to the grippers, the lack of paragraphing makes the text feel cluttered. Cohesive devices are minimal and somewhat repetitive, such as the frequent use of 'and' to connect clauses. To reach a higher band, you should organize your ideas into distinct paragraphs—perhaps one for the structural components and another for the functional aspects—and use a wider variety of linking words to guide the reader through the description.

Lexical Resource — Band 5.5

The vocabulary is generally adequate for the task but lacks the precision and academic tone required for a report. Phrases like 'god like precision' and 'you can say' are too informal for an IELTS Academic task. There are also spelling errors such as 'i' instead of 'in', 'movment', and 'perfectaly'. While the student successfully uses technical terms like 'sensors' and 'precision control', the overall range is limited. To improve, focus on using more formal, precise terminology and ensure careful proofreading to eliminate basic spelling mistakes that detract from the professional quality of the writing.

Grammatical Range and Accuracy — Band 5.0

The response contains several grammatical errors that affect the clarity of the writing. There are subject-verb agreement issues, such as 'It consist of' (should be 'consists') and 'gripper to rotate' (should be 'the gripper'). Additionally, there are punctuation errors and awkward phrasing, such as 'how much force is needed' and 'it picking'. The sentence structures are relatively simple, and there is a lack of complex grammatical forms. To improve, focus on subject-verb agreement, correct article usage, and incorporating a wider variety of complex sentence structures to demonstrate better control over English grammar.
