AI examiner evaluation

Task Achievement / Task Response — Band 4.5

The response fails to meet the minimum length requirement of 150 words, containing only 127 words, which negatively impacts Task Achievement. While the student attempts to describe the entire nine-step process from planting bamboo to making fabric, the overview is extremely basic and lacks clarity ('prepare overall this is nine step to made bamboi fabric'). Key features such as the transformation of strips into pulp and the addition of water and amine oxide are mentioned, but the description remains rudimentary, fragmented, and under-developed. To achieve a higher band, the writer needs to provide a fully developed overview and ensure all stages are described with adequate detail and well above the word count threshold.

Coherence and Cohesion — Band 4.0

The response shows an attempt to sequence the stages chronologically using basic transitional markers like 'first', 'second', and 'next'. However, paragraphing is extremely poor, with the entire text collapsed into two run-on paragraphs that lack punctuation and clear structural boundaries. Cohesive devices are repetitive and sometimes inaccurate ('while rose significantly'), leading to a lack of logical progression. Referencing between sentences is frequently unclear, making it difficult for the reader to follow the flow of the process easily. Improving sentence boundaries and paragraph organization is essential for a better score.

Lexical Resource — Band 4.0

The vocabulary used is very basic and repetitive, with numerous spelling and word-choice errors throughout the text ('fillter' instead of filter, 'bamboi' instead of bamboo, 'strip' instead of strips). There is little evidence of less common lexical items, and terms taken directly from the prompt are often misspelled or misused. Vocabulary control is weak, and errors frequently strain the reader's understanding. To improve, the student should expand their working vocabulary for describing manufacturing processes and practice accurate spelling and collocation.

Grammatical Range and Accuracy — Band 4.0

Grammatical control is severely limited. The response consists almost entirely of poorly structured, fragmented clauses linked incorrectly without proper punctuation or conjunctions ('the diagram illustrates show how bamboo fabric made in mill and prepare'). There is a complete lack of complex sentence structures, and basic grammatical rules regarding subject-verb agreement and articles are frequently ignored. Frequent errors cause substantial difficulty for the reader and obscure meaning. A strong focus on basic sentence construction, punctuation, and tense consistency is required.
