Comparative Grammatical Error Analysis: Grade XI Science vs. Social Science Students

Introduction

English as a Foreign Language (EFL) instruction in high school often reveals diverse proficiency levels among students depending on their academic tracks. In the Indonesian curriculum, Grade XI students are typically streamed into Natural Science (IPA) and Social Science (IPS) classes. An analysis of their narrative writing provides a unique window into how academic focus and cognitive habits influence linguistic accuracy and grammatical competency.

The Nature of Narrative Writing

Narrative writing requires students to use the past tense, chronological sequencing, and descriptive language. While science students are often trained in structured, data-driven report writing, social science students may be more accustomed to interpretive and descriptive essays. Analyzing grammatical errorssuch as verb tense inconsistencies, misuse of articles, and subject-verb agreementreveals the specific linguistic challenges each group faces.

Common Grammatical Errors Observed

Regardless of their academic stream, both groups tend to struggle with universal EFL challenges. The most frequent errors include:

• Verb Tense Inconsistency: Failing to maintain past tense throughout the narrative.
• Article Misuse: Omission or incorrect application of 'a', 'an', and 'the'.
• Subject-Verb Agreement: Difficulty aligning singular/plural subjects with verb forms.
• Word Choice (Diction): Improper use of vocabulary leading to ambiguous meaning.

Comparative Analysis: Science vs. Social Science

While the error categories are similar, the frequency and specific manifestations differ. Research indicates that Natural Science students often show a higher proficiency in structural precision, potentially due to the logical and systematic nature of their coursework. Their errors are frequently related to "interlingual" interference, where the structures of their native language influence their English output.

Conversely, Social Science students frequently demonstrate more creativity in their storytelling but exhibit a higher volume of "intralingual" errors. These occur when students over-generalize rules of the English language. For instance, a Social Science student might prioritize narrative flow over strict grammatical adherence, leading to more complex sentence structures that, while creative, often contain errors in syntax and clause modification.

The Impact of Academic Track on Linguistic Style

The academic environment acts as a subtle shaper of language production. Natural Science students, accustomed to the objective nature of scientific reporting, often produce narrative texts that are chronologically rigid and lean. Their grammatical errors are often "errors of omission," where they leave out necessary elements because they are focused on brevity. In contrast, Social Science students, whose studies involve social phenomena and humanities, often employ more descriptive adjectives and complex emotional narratives, leading to "errors of addition" or complex structural failures.

Pedagogical Implications

Understanding these differences allows educators to tailor their teaching methods. For Natural Science students, teachers might focus on expanding their expressive vocabulary to enrich their narratives. For Social Science students, the focus should remain on grammatical tightening and structural editing to ensure their complex ideas are conveyed with clarity.

Conclusion

Grammatical error analysis is not merely about finding mistakes; it is about understanding the cognitive process behind student writing. While Grade XI students across both streams face hurdles in mastering English, the nature of these hurdles is intrinsically linked to their academic orientation. By recognizing these patterns, educators can foster a more effective learning environment that addresses the unique linguistic development of both science and social science cohorts.
