Task Achievement / Task Response — Band 4.0

The response attempts to describe the process, but it fails to provide a clear, logical overview of the steps involved. Instead of describing the mechanical process of the water clock, the response focuses on listing the labels provided in the diagram. The instructions are not clearly explained, and the description of the 'process' is fragmented and difficult to follow. The response lacks a clear summary of the overall mechanism, which is essential for a process description task. Consequently, the information is not well-developed, and the reader does not gain a clear understanding of how the device actually functions.

Coherence and Cohesion — Band 4.0

The essay is divided into paragraphs, but the internal structure is weak. There is a lack of logical progression between sentences, and the use of cohesive devices is very limited and often inaccurate (e.g., 'The first in the top of name is...'). The referencing is unclear, making it difficult to track the steps of the process. The transition between the introduction and the body paragraphs is abrupt, and the overall flow is disjointed, which significantly hinders the reader's ability to follow the sequence of events.

Lexical Resource — Band 4.0

The vocabulary is very basic and repetitive. There are frequent errors in word choice and collocation, such as 'help to down the water' instead of 'facilitate water flow' or 'level balance of glue' instead of 'water level regulation'. The student struggles to use precise technical terms to describe the components or the actions involved in the process. Many phrases are awkward or non-standard, which limits the clarity of the description and indicates a restricted range of vocabulary suitable for an academic task.

Grammatical Range and Accuracy — Band 4.0

The response contains frequent grammatical errors that impede communication. There are consistent issues with subject-verb agreement (e.g., 'The diagram illustrate'), article usage, and sentence structure. Many sentences are poorly constructed, making them difficult to parse (e.g., 'the we need to finger away from hole because now that's water slowly down'). There is a lack of complex sentence structures, and the errors in basic grammar are pervasive throughout the text, which significantly affects the readability of the report.
