Write a report for a university lecturer describing the information below.

HOW TO BUILD YOUR OWN WATER CLOCK

Student answer (Band 5.0)

The above given chart illustrates the manufacturing process of water clock.

Overall, building own water clock consist on seven stages, where multiple other resources are also needed such as glue, straw, plastic bottle, and tape.

Standing stand carried two plastic bottles one from high and other one is below. While upward bottle was hold by tape. Furthermore, the process of building own clock start after setup of these materials. In initial stage, water filled in upper plastic bottle when turing tap on, while on the bottom of upper bottle their was a tiny hole, which was covered with finger in second step. In third step, after filling of water in plastic bottle as per capicity to overflow from it, where straw added by glue waste the overflow of water on the ground. Meanwhile, stage four, shows excat level of capicity to hold the water.

In fifth stage, finger was taken away from hole and slowly water drop in to the surface level bottle, where bottle calculate level per minute that was step number six. In final step, the whole method repeated after emptiy of the water.

AI examiner evaluation

Task Achievement / Task Response: Band 5.0

The student attempts to describe the process of making a water clock, covering the general sequence from setting up the materials to timing things. However, the response suffers from significant inaccuracies and misinterpretations of the diagram. For instance, the description states that the water overflows onto the ground via the straw, whereas the diagram shows the straw acting as an overflow drain to maintain a constant level. Furthermore, some stages are confused or overly convoluted, such as the explanation of calibration lines and the lower bottle. While an overview is attempted, the lack of precision in reporting the visual data places this criterion in the Band 5 range.

Coherence and Cohesion: Band 5.0

The response is organised into a brief introduction and two body paragraphs, attempting to follow the chronological stages of the diagram. However, the progression is frequently disrupted by awkward phrasing and poor mechanical cohesion. Phrases like 'While upward bottle was hold by tape' and 'Meanwhile, stage four, shows excat level' create a disjointed reading experience. Reference words and cohesive devices are often inaccurate or missing, making it difficult to follow the logical flow of the instructions. Paragraphing is rudimentary, leading to a Band 5 score for coherence and cohesion.

Lexical Resource: Band 5.0

The student demonstrates a limited range of vocabulary with noticeable lexical errors and awkward collocations. Examples include 'manufacturing process' for a DIY craft, 'consist on' instead of 'consists of', 'Standing stand carried', and 'capicity'. While the student uses some relevant topic-specific terms like 'plastic bottle', 'straw', and 'glue', the frequent spelling and word-choice errors cause difficulty for the reader and prevent the response from achieving a higher band. The lexical resource is characteristic of Band 5.

Grammatical Range and Accuracy: Band 5.0

The grammatical structure is heavily flawed, featuring a limited range of complex sentence attempts that are consistently faulty. Examples of grammatical errors include 'building own water clock' (missing articles), 'water filled in upper plastic bottle when turing tap on' (passive/active confusion), and 'their was a tiny hole'. Punctuation is also weak, and sentences often contain multiple errors that impede clear communication. Because error-free sentences are rare and grammatical control is weak throughout, the response earns a Band 5 for grammatical range and accuracy.
