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)

This diagram is about how a mechanical arm works.It is a human's arm replacement which is used for mechanical purposes. It contains motors which make it useful. it also contains elbows which give it flexibility and help it to move in possible directions.Thee is a base where it stands. then there is a arm/shoulder which helps to raise it. Then there is an elbow which give flexibility to move in required directions.Then there is a grip that helps user to rotate it according to requirement and in the end there is a grip which have built in sensors which helps to control or pick objects.It is a very useful instrument to to do industrial word easily and more effectively. The main example of mechanical arm are drill machines and spray paint machines weld metal machine.It make work easier for people where human arm can not do work more effectively.These devices work with motors.and helps to increase productivity.

Task Achievement / Task Response — Band 5.5

The response attempts to describe the mechanical arm, but it fails to effectively summarise the main features or make clear comparisons between the mechanical and human arm as requested. The description is somewhat disjointed and relies on listing parts rather than providing a cohesive overview of the mechanism. Furthermore, the inclusion of external information about industrial applications (e.g., drill machines, spray paint) is not supported by the provided diagram, which is a significant deviation from the task requirements. To improve, focus strictly on the visual information provided and structure the response to highlight the functional similarities between the two systems.

Coherence and Cohesion — Band 5.5

The response lacks clear paragraphing, which makes it difficult to follow the logical progression of the description. While there are some attempts at sequencing (e.g., 'then there is'), the use of cohesive devices is repetitive and mechanical. The text feels like a series of disjointed sentences rather than a well-structured report. To improve, you should group related information into distinct paragraphs—for example, one for the components of the arm and another for the functional comparison—and use a wider variety of linking words to connect your ideas more fluidly.

Lexical Resource — Band 5.5

The vocabulary is quite basic and repetitive, relying heavily on simple terms like 'useful', 'helps', and 'work'. There is little attempt to use precise technical terminology related to the diagram. Some word choices are inaccurate, such as 'industrial word' instead of 'industrial work'. To reach a higher band, you need to incorporate more specific vocabulary related to mechanical engineering and anatomical functions, and demonstrate a better grasp of collocations to describe how the components interact with one another.

Grammatical Range and Accuracy — Band 5.5

The response contains frequent grammatical errors, including issues with subject-verb agreement (e.g., 'grip which have built in sensors'), punctuation (missing spaces after periods), and sentence structure. The range of structures is limited, consisting mostly of simple sentences. There are also several spelling errors and typos, such as 'Thee' instead of 'There'. To improve, focus on mastering basic sentence construction, ensuring correct punctuation, and proofreading for minor errors that distract the reader from your message.
