Task Achievement / Task Response — Band 4.0
The response attempts to describe the process of building a water clock, but it fails to clearly identify or explain the key stages shown in the diagram. The description is fragmented and lacks a logical flow, making it difficult for the reader to understand the actual mechanism. Many parts of the process, such as the specific components or the scientific principle behind the clock, are either omitted or described in a way that is confusing and inaccurate. The response does not provide a clear overview of the process, which is essential for an Academic Task 1 report. Consequently, the information is not well-developed or clearly presented.
Coherence and Cohesion — Band 4.0
The essay lacks a logical structure. While there are paragraph breaks, the ideas within them are disjointed and do not follow a clear sequence. Cohesive devices are either missing or used incorrectly, such as 'according to the it will take some timesit', which disrupts the flow of information. The referencing is unclear, and the transition between the steps of the process is mechanical and confusing. The lack of a clear introduction or a logical progression of steps makes the text difficult to follow, which significantly impacts the overall coherence of the report.
Lexical Resource — Band 4.0
The vocabulary is very limited and repetitive. The student relies on basic words like 'tap', 'water', 'bottle', and 'process', which are insufficient to describe a technical diagram effectively. There are significant issues with word choice and collocation, such as 'away from the hole finger' and 'nect cut off', which make the meaning unclear. The lack of precise terminology to describe the components or the physical actions involved in the process prevents the student from conveying the information accurately. The range of vocabulary is not adequate for the task.
Grammatical Range and Accuracy — Band 4.0
The grammatical control is weak throughout the response. There are frequent errors in sentence structure, verb tense, and word order, such as 'the water will be flow in to' and 'the water will be goes to'. Punctuation is also problematic, with run-on sentences and missing articles. The student attempts to use complex sentences, but these are consistently faulty, leading to a breakdown in communication. The high frequency of errors makes the text difficult to read and understand, and there is very little evidence of accurate, complex grammatical structures.
