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)

The diagram illustarates how robotic arm works and joint of robotic arm fetures in same order as human arm works.

Overall, it can be noiced that process starts with computer coding and it ends with working robotic machine. While alternative end effectores run with same factors

starting with, first computer comand, computer control three precision motors. first motor control arms bas for movement. whereas, second motor use for elbow it helps aloows to flexibility and movement. Moreover those two motors helps arms shulder rais and lower arm and oththe motor help pivot it is endles arm of machine.

Furthermore, last motor help built sensor control force to gripper and allows to rotare it called wrist of arm. In addtion spray pain , drill holes and weld metal works on that theory. it process is vey complex and hard it need computer to oprates the machine and robtic arm as well.

Task Achievement / Task Response — Band 5.5

The response attempts to describe the mechanical arm, but it fails to clearly explain the comparison between the robotic joints and human anatomy as requested. While the main features are identified, the description of the process is fragmented and lacks clarity. The explanation of how the motors function is difficult to follow due to imprecise terminology and a lack of logical flow. The overview provided is very brief and does not effectively summarize the key features of the diagram. To improve, you should focus on clearly identifying the specific components (e.g., base, elbow, wrist) and explicitly stating how they mirror human movement, rather than listing them in a disjointed manner.

Coherence and Cohesion — Band 5.5

The essay is organized into paragraphs, but the logical progression of ideas is weak. Cohesive devices such as 'starting with', 'moreover', and 'furthermore' are used, but they are often applied incorrectly or in a mechanical way that does not improve the flow of information. Referencing is frequently unclear, making it difficult for the reader to track which motor or part is being discussed. The transition between the description of the motors and the final applications of the arm is abrupt. Improved use of linking words and clearer sentence structure would significantly enhance the coherence of your writing.

Lexical Resource — Band 5.5

The vocabulary is limited and often inaccurate, which hinders the clarity of the technical description. There are numerous spelling errors, such as 'illustarates', 'noiced', 'comand', 'aloows', 'shulder', and 'oprates'. The word choice is often imprecise; for example, 'alternative end effectores' and 'endles arm' do not accurately describe the mechanical components shown in the diagram. You need to focus on learning technical vocabulary related to diagrams and processes, and pay closer attention to spelling and word formation to ensure your meaning is conveyed accurately.

Grammatical Range and Accuracy — Band 5.5

The response contains frequent grammatical errors that often impede communication. There are consistent issues with subject-verb agreement (e.g., 'computer control three precision motors'), missing articles, and incorrect verb forms (e.g., 'last motor help built sensor'). The sentence structures are mostly simple or contain errors when attempting complex constructions. Punctuation is also inconsistent, with missing commas and incorrect capitalization. To reach a higher band, you must focus on basic sentence construction, ensuring that subjects and verbs agree and that tense usage is consistent throughout the description of the process.
