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 diagram demonstrates the procedure of how a mechanical arms operate, and how the joints that make up the arm function in the identical way as those in a human arm.

Overall, there are several motors joint in the arm and are controlled by the computers. The main required source to operate the arm is electricity.

There are several computer controlled motors joint in the different pats in the arms. first, there is the base with first motor, from where the metal rounded rod is mounted slightly on the left side. At the end of that rod another rod is joint with the motor. at the end of the second rod another third motor is joint with the mouth of crave shape metal as human two fingers., which is called gripper and that is buit

Task Achievement / Task Response — Band 4.5

The response fails to meet the minimum word count requirement of 150 words, which significantly impacts the ability to fully address the task. While the introduction attempts to paraphrase the prompt, the description of the mechanical arm is incomplete and trails off at the end. The main features are identified, but the comparison to the human arm is not sufficiently developed, and the explanation of the mechanical components lacks the necessary detail to provide a comprehensive summary. To improve, ensure all parts of the diagram are described clearly and the response reaches the required length to allow for full development of ideas.

Coherence and Cohesion — Band 5.0

The response is organised into short paragraphs, but the progression of ideas is hindered by the incomplete nature of the final sentence. Cohesive devices are used in a very basic manner, such as 'first' and 'overall', but the lack of flow between sentences makes the text feel disjointed. Referencing is sometimes unclear, and the paragraphing is not used effectively to structure the information logically. To improve, focus on using a wider range of linking words and ensure that each paragraph has a clear topic sentence that connects to the overall summary.

Lexical Resource — Band 5.0

The vocabulary is limited and repetitive, with several errors in word choice and spelling, such as 'pats' instead of 'parts', 'crave' instead of 'curved', and 'buit' which is incomplete. The range of vocabulary is insufficient to describe the technical aspects of the diagram with precision. There is an attempt to use descriptive language, but it is often inaccurate or poorly collocated. To improve, focus on learning technical terminology related to mechanical processes and practice using more precise adjectives and nouns to describe shapes and functions.

Grammatical Range and Accuracy — Band 5.0

The response contains frequent grammatical errors, including subject-verb agreement issues ('mechanical arms operate', 'motors joint') and incorrect word forms. Sentence structures are generally simple, and the attempt at more complex structures is marred by errors and the unfinished final sentence. Punctuation is also inconsistent, with missing capital letters at the start of sentences and incorrect comma usage. To improve, focus on mastering basic sentence construction, subject-verb agreement, and proofreading for common errors like missing articles and incorrect verb tenses.
