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)

Here is the picture shown in comparision of mechanical arm which performs the similar functions performed by human arms.The mechanical arm is being controlled by machine called computer. There motors which are controlled by computer which gives command to move and perform the task of different kinds similar to that of human hand. Mechanical arm has parts like elbow- allows movement , gripper- built in sensors control force ,pivot- enables arm to rotate, wrist- allows gripper to rotate, shoulder- raises arm. This all functions and parts are similar to that of humans elbow- to move hands, wrist - to hold back, shoulder - to allow movement, but humans have fingers in number of 5 which allows the humans to perform multiple and distinctive tasks at a time.

AI examiner evaluation

Task Achievement / Task Response — Band 4.5

The student attempts to summarise the diagram, mentioning key components such as the computer, motors, elbow, gripper, pivot, wrist, and shoulder, and comparing them to human arms. However, the response falls significantly short of the 150-word minimum, containing only 127 words. Furthermore, the overview is weak, and some details are vague or inaccurate, such as stating that humans have a wrist to hold back. Because the length requirement is not met and the information is only partially developed, this is penalised under Task Achievement.

Coherence and Cohesion — Band 5.0

The text lacks proper paragraphing, presented as a single dense block of text, which severely impacts the visual organisation and logical flow. While there are basic attempts to link ideas, referencing is often unclear, such as the abrupt transition in 'There motors which are controlled by computer which gives command'. Cohesive devices are basic and repetitive, and the overall progression from describing the mechanical arm to human comparison is disjointed. Therefore, Coherence and Cohesion is limited to a Band 5.0.

Lexical Resource — Band 5.0

The vocabulary used is quite basic and repetitive ('performed', 'similar', 'parts', 'humans'). There are several direct lifts from the prompt labels rather than paraphrasing. Errors in word choice and spelling are noticeable, such as 'comparision' instead of 'comparison', 'There motors' instead of 'There are motors', and awkward phrasing like 'humans have fingers in number of 5'. This range is minimally adequate for the task, resulting in a Band 5.0.

Grammatical Range and Accuracy — Band 5.0

The response features a very limited range of sentence structures, relying mostly on simple sentences joined by basic conjunctions or relative pronouns. There are frequent grammatical errors, including subject-verb agreement issues ('There motors which are controlled'), missing articles ('computer' instead of 'a computer'), and run-on structures. Punctuation errors are also present, such as missing spaces before commas and periods. These errors cause some difficulty for the reader, fitting the Band 5.0 descriptors.
