Abstract

Perkembangan teknologi komunikasi telah mengubah cara masyarakat berinteraksi, terutama di media sosial. Penelitian ini bertujuan untuk menganalisis variasi dan pola penggunaan bahasa Indonesia di platform Instagram dan X (Twitter) oleh mahasiswa Universitas Negeri Medan. Metode yang digunakan adalah deskriptif kualitatif dengan teknik observasi virtual dan dokumentasi. Hasil penelitian menunjukkan bahwa mahasiswa cenderung menggunakan bahasa non-baku, seperti bahasa gaul, campur kode, dan alih kode dalam komunikasi di media sosial. Variasi bahasa ini dipengaruhi oleh faktor sosial, budaya, dan karakteristik platform digital. Analisis lebih lanjut dilakukan pada aspek morfologi, sintaksis, dan leksikon untuk memahami dinamika penggunaan bahasa dalam konteks digital. Penelitian ini diharapkan dapat memberikan kontribusi terhadap kajian sosiolinguistik dan menjadi bahan pertimbangan dalam pembinaan bahasa Indonesia di lingkungan akademik.

Abstract

Persistent misconceptions about temperature and heat often undermine students’ progress in thermodynamics.  This study therefore analysed Grade-11 learners’ conceptual understanding of these topics using a Four-Tier Multiple-Choice Diagnostic Test, an instrument that registers answer correctness, explanatory reasoning, and confidence on both selections.  A descriptive quantitative design was adopted.  Thirty students from class XI-34 of SMAN 3 Medan completed a five-item test that had been validated by experts and piloted for clarity; psychometric checks on the study sample confirmed good reliability (Cronbach’s α = 0.88) and adequate item validity (four of five items met the r-table criterion).  Responses were coded into four epistemic categories—Understands Concept (UC), Lacks Knowledge (LK), Misconception (MC), and Error (E)—and analysed. Findings show that overall achievement averaged 30 %, with individual scores ranging from 0 % to 80 %.  Across the entire data set, only 27.3 % of responses were classified as UC, while 19.8 % fell into LK, 45.3 % into MC, and 8.0 % into E.  Item-level analysis revealed that the highest misconception rate (73.3 %) occurred on the question concerning the effect of temperature on objects, whereas the phase-change item yielded the strongest understanding (46.7 % UC, 20 % MC).  These results confirm that misconceptions—especially the conflation of heat with temperature—constitute the principal barrier to coherent learning in this cohort. The study underscores the diagnostic power of four-tier instruments and recommends their wider use across other physics domains, enabling teachers to design confidence-sensitive interventions that directly target high-certainty errors and reinforce fragile correct ideas.
