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)

The data illustrates the mechanism arm works and how they connected that made a function in the same way as those in human arm. Now elaborate the information by selecting and

reporting the main features, and make comparisons where relevant.

Overall the computer divided into three motors and each motor connected to the special part which seemed as the organ of human. The first motor connected to the base and its represented the shoulder. Moreover the motor joined the part which movement represented the elbow. Furthermore the third motor connected gripper ( bulit-in sensors control force).

In contrast these mechanics diagram represented the other parts like wrist -allows gripper which looked like a single pipe line and it connected to gripper bulit in s

Task Achievement / Task Response — Band 4.0

The response fails to meet the minimum word count requirement of 150 words, which significantly impacts the task achievement score. Furthermore, the content is incomplete; the text ends abruptly mid-sentence, leaving the description of the mechanical arm unfinished. While the student attempts to identify the main features, such as the motors and their human-arm counterparts (shoulder, elbow, wrist), the lack of development and the failure to complete the report prevent a higher score. The introduction also incorrectly includes the prompt's instructions rather than paraphrasing the task itself, which is a major procedural error.

Coherence and Cohesion — Band 5.0

The response shows some attempt at logical organization by using transition words like 'Overall', 'Moreover', 'Furthermore', and 'In contrast'. However, the progression is hindered by the incomplete nature of the text and the lack of a clear structure. Paragraphing is attempted but is ineffective due to the brevity and the abrupt ending. Referencing is sometimes unclear, such as in the phrase 'the computer divided into three motors', which does not accurately describe the diagram provided. The flow of information is disrupted by the unfinished sentences.

Lexical Resource — Band 5.0

The vocabulary is limited and repetitive. The student relies on basic terms like 'connected', 'part', and 'looked like'. There are several instances of awkward word choice and collocation errors, such as 'mechanism arm works' instead of 'mechanical arm' and 'bulit-in' (spelling error). The student struggles to use precise technical terminology to describe the mechanical components, which is essential for an Academic Task 1 response. The range of vocabulary is insufficient to convey the information clearly or with any degree of sophistication.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors that impede clarity. Examples include 'the mechanism arm works and how they connected that made a function', which is syntactically incorrect. There are issues with verb tense consistency, missing articles, and incorrect word forms (e.g., 'its represented' instead of 'it represented'). The sentence structures are mostly simple, and the attempt at more complex structures results in errors that make the meaning difficult to follow. Punctuation is also inconsistent, particularly at the end of the text where the sentence is left hanging.
