Student answer (Band 4.0)

I think that the question is the controversial one that it is important goal for science to improv peoples lives, I disagree with this question because there are many other works and managements that science should do.For example they have many goals of makin Air planes, Buses and many other things. Science doesnot have a single goal, Many people think thet they should have only one goal of improving peoples live, it is not true.

On the other hand, I think that they should mave peoples life easy and convenient by improving roads and making new buildings and colleges. In this way the way for imployers increases and they earn more money according to their need, in this way the life of a citizen improved by making sites.

AI examiner evaluation

Task Achievement / Task Response — Band 4.0

The response fails to meet the minimum length requirement of 250 words, containing only 128 words. As a result, the development of ideas is severely restricted. The student attempts to address the prompt by expressing a disagreement with the statement, claiming that science has other goals such as making airplanes and buses. However, the position is somewhat confused as the writer later suggests that science should make people's lives easy by improving roads and buildings, which actually aligns with the prompt rather than opposing it. Due to the severe under-length issue and very limited idea development, this response falls under Band 4.

Coherence and Cohesion — Band 4.0

The response is divided into two short paragraphs, but the overall organization lacks logical progression and clear signposting. While basic cohesive devices such as 'For example' and 'On the other hand' are attempted, their use is somewhat mechanical and does not successfully guide the reader through a well-structured argument. Referencing is occasionally unclear, particularly with pronouns like 'they' and 'it', which creates confusion regarding whether the writer is referring to science, scientists, or governments. Paragraphing is present, but the abrupt shift in ideas without adequate transitional support limits the overall coherence, placing the response at Band 4.

Lexical Resource — Band 4.0

The vocabulary used is basic and repetitive throughout the text. Words such as 'goal', 'make', and 'life' are recycled frequently without variation. There are noticeable lexical errors, such as 'improv' instead of 'improve', 'makin' for 'making', and 'imployers' instead of 'employers' or 'employment'. The student attempts some less common vocabulary like 'convenient' and 'controversial', but the limited range and frequent errors in word choice and spelling significantly constrain communication. This performance aligns with the descriptors for Band 4.

Grammatical Range and Accuracy — Band 4.0

The student relies heavily on simple sentence structures, and attempts at complex sentences tend to be faulty, as seen in the convoluted opening sentence: 'I think that the question is the controversial one that it is important goal for science to improv peoples lives, I disagree with this question because...'. Grammatical and punctuation errors are frequent, including missing apostrophes for possessives ('peoples lives'), incorrect verb forms ('Science doesnot have'), and run-on sentences. These frequent errors cause difficulty for the reader and demonstrate very limited grammatical control, meriting a Band 4.
