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)

In this diagram , it shows a machine which is same as the arm works . first of all i compare the motor that held on the back of a gripper its look like the human arm wrist ,we can grasp anything from this , now we can discuss about the two motors that are combine to each other and its look like same as the human elbow and it rotates it anywhere you want .

It is very useful for any machine . in third place we say about the base which is look as the human shoulder . all of mechanics made machine like an human body parts because it gives the idea very easily. the bread and butter of all mechanics is that make machine like drill machines , spray paints machine and weld metals . in short , the motor of lower arm, elbow and the gripper are connect with the precision control of motor which is on the computer .

Task Achievement / Task Response — Band 5.5

The response attempts to describe the mechanical arm but fails to provide a clear, objective summary of the diagram. It focuses on subjective commentary, such as 'it is very useful for any machine' and 'the bread and butter of all mechanics', rather than reporting the technical features shown. While the comparison between the mechanical joints and human anatomy is mentioned, the description lacks the precision required for an Academic Task 1 report. The response does not clearly identify the main features or provide a structured overview of the mechanical process, leading to a fragmented presentation of the information.

Coherence and Cohesion — Band 5.5

The essay lacks a clear logical progression. The paragraphing is insufficient, with the text appearing as a single block of ideas rather than a structured report. Cohesive devices are used in a very basic and repetitive manner, such as 'first of all', 'in third place', and 'in short'. These transitions feel mechanical and do not effectively link the ideas together. The lack of a clear introduction and overview makes the text difficult to follow, and the referencing of parts of the diagram is often imprecise, which hinders the overall flow of information.

Lexical Resource — Band 5.5

The vocabulary is quite limited and repetitive. Phrases like 'it looks like' are used multiple times, which restricts the range of expression. There are also issues with word choice and collocation, such as 'all of mechanics made machine' and 'weld metals', which are not used in a natural or accurate way. The student struggles to use technical terminology appropriate for describing a mechanical diagram, relying instead on informal or imprecise language. To improve, the student needs to focus on using more precise nouns and verbs related to mechanical engineering and structural description.

Grammatical Range and Accuracy — Band 5.5

The response contains frequent grammatical errors that occasionally impede clarity. There are issues with subject-verb agreement ('the motor... are connect'), incorrect verb forms ('it rotates it anywhere'), and run-on sentences. The range of structures is limited, consisting mostly of simple sentences with some awkward attempts at complex structures. Punctuation is also inconsistent, with spaces before commas and a lack of proper sentence boundaries. While the meaning is generally understandable, the high frequency of errors in basic grammar and sentence construction prevents the response from reaching a higher band.
