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 illustrates how mechanical arm work and how the joints that make up the arm function in same way as those in individual arm.

To begin with, in the pictorial depiction there are three motors are controlled by computer . three motors have diverse work and they helps to operate mechanical arm significantly, the first motor is an elbow of mechanical arm which is helps to movements and allow flexibility .

In additionally, second motor is helps to hold something and it operate built in sensos for control force. third one is use in base of mechanical aem it is helps to rise shoulder up and down. drastically, the mechanical arm is move as usal human hand whith help of motors . in this pictor mention one man sprey the colour on mechanical hand . and the human is use drill machin creat holl on metal a

Task Achievement / Task Response — Band 4.5

The response fails to meet the minimum word count requirement of 150 words, which negatively impacts the score. While the student attempts to describe the mechanical arm and its joints, the summary is underdeveloped and lacks a clear overview of the main features. The description of the motors is somewhat disjointed, and the comparison between the mechanical arm and the human arm is not fully articulated. Furthermore, the inclusion of specific details about a person spraying color or drilling holes is somewhat tangential and does not contribute to a cohesive summary of the mechanical arm's function as presented in the diagram. A more structured approach focusing on the core mechanical components and their specific roles is needed.

Coherence and Cohesion — Band 5.0

The response lacks a clear logical progression. While there is an attempt to use transition signals like 'To begin with' and 'In additionally', these are often used incorrectly or lead to awkward phrasing. The paragraphing is insufficient, and the flow between sentences is frequently interrupted by grammatical errors, making the text difficult to follow. The relationship between the ideas is not clearly established, and the referencing is often confusing, particularly when describing the functions of the three motors. To improve, the student should focus on grouping related information into distinct paragraphs and using cohesive devices more naturally to connect ideas.

Lexical Resource — Band 5.0

The vocabulary is quite limited and repetitive. The student relies on basic terms such as 'work', 'helps', and 'use', which restricts the ability to describe the technical nature of the diagram precisely. There are several instances of incorrect word choice, such as 'pictorial depiction' and 'sensos', as well as spelling errors like 'aem' and 'holl'. The range is insufficient to convey the technical information effectively. To achieve a higher band, the student needs to incorporate more precise, topic-specific vocabulary related to mechanics and engineering, and pay closer attention to accurate spelling and word formation.

Grammatical Range and Accuracy — Band 4.5

The response contains frequent grammatical errors that often impede communication. There are persistent issues with subject-verb agreement (e.g., 'mechanical arm work', 'three motors are controlled'), article usage, and sentence structure. Many sentences are fragmented or lack necessary components, such as 'third one is use in base'. The lack of control over basic grammar, including punctuation and capitalization, is a significant weakness. The student relies almost exclusively on simple sentence structures, and attempts at more complex constructions are consistently inaccurate. A focus on mastering basic sentence construction and proofreading for common errors is essential for improvement.
