Task Achievement / Task Response — Band 4.0

The response fails to meet the minimum word count requirement of 150 words, reaching only 77 words. This significantly impacts the task achievement as the process is described in a very superficial manner. While the student identifies the main stages of the bamboo manufacturing process, the lack of detail and the failure to provide a proper overview or a clear summary of the main features means the task is only partially addressed. To improve, the student must expand on each stage of the process, provide a clear introduction, and ensure the response meets the length requirement to allow for a full development of the information provided in the diagram.

Coherence and Cohesion — Band 4.0

The response is written as a single, long, run-on sentence, which makes it difficult to follow. There is no paragraphing, and the use of cohesive devices is repetitive and mechanical. Phrases like 'subsequently' and 'afterwards' are used repeatedly, which creates a monotonous flow. The lack of punctuation, particularly full stops to separate distinct stages of the process, severely hinders the logical progression of the information. To improve, the student should use clear paragraphing to separate the introduction from the body stages and use a wider variety of linking words and punctuation to create a more natural flow.

Lexical Resource — Band 4.0

The vocabulary is very basic and repetitive. The student relies on simple verbs like 'cutted' (which is grammatically incorrect) and 'made'. There is little attempt to use more precise or academic vocabulary related to manufacturing processes, such as 'processed', 'transformed', or 'converted'. The repetition of words like 'strips', 'fibres', and 'yarn' without variation or descriptive adjectives limits the range. To improve, the student should focus on learning process-specific vocabulary and avoid repeating the same verbs throughout the text.

Grammatical Range and Accuracy — Band 4.0

The grammatical control is weak. The entire response consists of a single, poorly punctuated sentence, which is a major error. There are frequent errors in verb forms, such as 'cutted' (the past participle of 'cut' is 'cut') and 'spinned' (the past participle of 'spin' is 'spun'). The lack of sentence boundaries and the misuse of basic verb tenses significantly impede readability. To improve, the student needs to focus on basic sentence structure, correct verb conjugation, and the appropriate use of punctuation to separate ideas.
