Task Achievement / Task Response: Band 5.0
The student attempts to summarise the nine-stage recycling process, mentioning the main steps such as collection, sorting, crushing, washing, pellet production, and manufacturing of final products. However, the response contains several inaccuracies and omissions regarding the sequence and details of the diagram. For example, the text states that glass is separated from plastic, which is not supported by the diagram, as only plastic bottles are processed. Furthermore, the description of the stages is slightly disjointed, stating that there are eight stages instead of nine before final production. While the overall purpose of the process is identified, the lack of precision and occasional misinterpretation of the visual data place this criterion at Band 5.0.
Coherence and Cohesion: Band 5.0
The response is organised into a brief introduction, body paragraphs, and a conclusion, which establishes a basic structural framework. However, the progression of ideas is frequently disrupted by poor paragraphing and mechanical or inaccurate use of cohesive devices, such as 'To begin with', 'Firstly', 'Secoundly', and 'Afther that'. Additionally, referencing is occasionally unclear, and the overall flow between sentences feels disjointed. These issues in logical organisation and cohesive control align with the Band 5 descriptor.
Lexical Resource: Band 4.0
The vocabulary used is relatively basic and repetitive, with frequent spelling errors throughout the text, such as 'reclying', 'diffetent', 'staes', 'peoples', 'pastic wates', 'dusbins', 'garbaged', 'Secoundly', 'seperate', 'Afther', 'compressior', 'seperated', 'artifical', and 'Futhermore'. The student attempts some less common vocabulary items (e.g., 'artificial material', 'compressor'), but the high frequency of spelling mistakes and awkward word choices (such as 'garbaged' and 'man made plastic') limits the score to Band 4.0, as these errors occasionally strain the reader.
Grammatical Range and Accuracy: Band 4.0
The student demonstrates a very limited range of grammatical structures, relying heavily on simple sentences with frequent structural and punctuation errors. There are numerous basic grammatical inaccuracies throughout the text, including subject-verb agreement issues (e.g., 'peoples throw', 'A truck collectes'), missing articles, and awkward phrasing (e.g., 'and take in particular place', 'process them for washing'). Complex structures are rarely attempted and, when used, are often faulty. The high frequency of errors across basic structures places this criterion at Band 4.0.
