AI examiner evaluation

Task Achievement / Task Response: Band 5.0

The student successfully identifies the main topic of the diagram, which is the manufacturing process of fabric from bamboo. However, the response fails to meet the minimum word count of 150 words, containing only 126 words, which results in a penalty under Task Achievement. While all nine steps are mentioned in sequence from planting to final clothing items, the overview sentence is rather simplistic and informal, claiming that 'the whole process will be demolished' if a step is omitted. The description lacks a well-developed summary of key features and overall trends, remaining a basic, mechanical list of steps.

Coherence and Cohesion: Band 4.0

The response suffers from severe punctuation issues, specifically a lack of full stops, resulting in a single massive run-on sentence for the entire body paragraph. Cohesive devices such as 'then', 'afterwards', 'after that', and 'subsequently' are overused in a repetitive, chain-like fashion to link clauses without proper punctuation. There is no clear paragraphing structure to separate the introduction, overview, and body steps. Although a logical chronological sequence is followed according to the diagram, the mechanical and faulty cohesion significantly disrupts the flow of the text.

Lexical Resource: Band 5.0

The vocabulary used is basic and repetitive, typical of a lower band. The student attempts some less common terms related to the process, such as 'amine oxide', 'pulp', 'filteration', and 'spun', but these are accompanied by spelling errors like 'filteration' and 'soften' instead of 'softened'. Word choices are sometimes awkward or overly colloquial, such as using 'demolished' to describe a broken industrial process. The range of vocabulary is barely adequate to communicate the basic steps of the diagram.

Grammatical Range and Accuracy: Band 4.0

The grammatical range is extremely limited due to the absence of proper punctuation. The entire response consists of comma splices and run-on structures rather than distinct sentences. There are frequent errors in verb forms and word forms, such as 'the wood is cutted' (incorrect past participle), 'fibres are soften' (missing passive participle ending), and 'is weaved' (missing subject pronoun). These frequent structural and mechanical errors cause considerable difficulty for the reader and demonstrate poor control over basic sentence boundaries.
