AI examiner evaluation

Task Achievement / Task Response — Band 2.0

The student has written a response about a line graph regarding goods transport in the UK. However, the input prompt provided a diagram illustrating how a mechanical arm works and compares its joints to a human arm. This represents a complete misinterpretation of the task, as the student has described an entirely different visual (a line graph) that does not exist in the prompt. Furthermore, the response falls short of the 150-word minimum, containing only 139 words. Because the response is entirely off-topic and fails to address the actual prompt, it receives a low band score.

Coherence and Cohesion — Band 4.5

Despite being off-topic, the student attempts to structure the response with an introduction, an overview, and body paragraphs. Paragraphing is attempted, but transitions are weak and mechanical (e.g., 'In 1974...', 'Whereas water transport...'). Referencing is sometimes unclear, and the overall logical progression is disrupted by incorrect data referencing. Cohesive devices are used awkwardly, reflecting a basic level of organizational skill.

Lexical Resource — Band 4.0

The vocabulary used is repetitive and contains multiple spelling and lexical errors, such as 'dominants', 'tones' instead of tons, 'transoprt', and 'atleat upove'. While there are attempts at topic-specific vocabulary related to transport ('road transport', 'pipeline', 'million tons'), the severe inaccuracies and lack of alignment with the actual prompt limit the lexical score. The range of vocabulary is narrow and basic.

Grammatical Range and Accuracy — Band 4.5

The response features a mix of simple and attempted complex sentences, but grammatical accuracy is poor. There are noticeable errors in subject-verb agreement and tense usage, such as 'The units is measured' and 'Pipeline throughout recorded at lowest figure'. Prepositional errors and awkward phrasing also persist throughout the text. These errors occasionally cause difficulty for the reader.
