error_description: Word Redundancy: The original sentence uses a noun clause introduced by 〈what〉, leading to a redundant and complex structure. According to the principle of conciseness in English, 〈what〉 is superfluous here; removing it and reorganizing into the simple sentence 『he does a good job』 makes the expression more concise and clear.

error_severity: 3
error_description: Verb Tense Error: According to English grammar rules, the relative clause in this sentence describes a continuous teaching effect, belonging to a present simple tense context. The original sentence uses the past tense 〈enhanced〉, which is inconsistent with the overall tense logic and should be changed to the present simple third-person singular form 『enhances』 to make the sentence tense consistent and accurately express the continuous teaching effectiveness.

error_type: Subject-Verb Agreement Error
error_severity: 3
error_description: Subject-Verb Agreement Error: According to English grammar rules, when the gerund phrase 〈helping students to learn how to analyse and solve problems〉 acts as the subject, it is considered a singular concept. In the original sentence, the predicate verb 〈offer〉 is in the plural form, which is inconsistent with the subject in number and should be changed to the singular form 『offers』 to achieve subject-verb agreement.
