Task Achievement / Task Response — Band 5.0
The student attempts to describe the process of making a water clock, successfully identifying the overall nature of the diagram and noting that it involves multiple sequential stages. An overview is provided, capturing the general beginning and end of the process. However, the description of individual steps is frequently imprecise, underdeveloped, and difficult to follow due to poor phrasing (for instance, stating "fill top of bottle to overflow" or "constant the level near the straw"). Some key details from the visual process are missed or distorted. Consequently, the response addresses the task only partially and struggles to clearly convey all parts of the visual information, aligning best with a Band 5.0 descriptor.
Coherence and Cohesion — Band 5.0
The text is organised into basic paragraphs, including an introduction, an overview, and body paragraphs that attempt to follow the sequence of the diagram. However, the overall progression is heavily disrupted by awkward transitions, informal filler phrases such as "At a fleeting glance, the procedure...", and mechanical or repetitive cohesive devices like "Moving further". Furthermore, referencing is frequently unclear, making it difficult for the reader to track which bottle or object is being referred to at various points. Paragraphing is attempted, but internal cohesion is faulty. This performance fits the Band 5.0 descriptors for Coherence and Cohesion.
Lexical Resource — Band 5.0
The vocabulary used is limited and heavily influenced by basic or inaccurate word choices. The student relies on repetitive terms and direct, unnatural translations or forms (e.g., "palstic bottle", "atttached", "constant the level", "to away the finger"). There are noticeable spelling errors and word-formation issues throughout the response that cause significant strain for the reader. While a minimal range of everyday topic vocabulary is attempted, the frequent errors in word choice and collocation prevent the text from achieving a higher band, placing it firmly at Band 4.5, rounded to 5.0 based on the presence of some basic technical words related to the prompt.
Grammatical Range and Accuracy — Band 5.0
The response demonstrates a very limited range of grammatical structures, relying heavily on simple sentences or poorly constructed complex forms. Frequent grammatical errors are present throughout the text, including missing verbs, incorrect prepositions, tense inconsistencies, and word-order issues (e.g., "The rendered process chart give information...", "to build own water clock it requires", "the procedure... starts with on the tap"). Attempts at complex clauses result in structural breakdowns that frequently impede communication. Due to the high frequency of basic errors and the lack of accurate complex structures, this performance corresponds to a Band 4.5, recorded as 5.0.
