Abstract

Kasus narkoba yang melibatkan Inspektur Jenderal Polisi Teddy Minahasa adalah salah satu skandal polisi terbesar dalam sejarah. Penelitian ini memeriksa peristiwa tersebut secara kronologis, membahas pasal-pasal hukum yang dilanggar, hukuman yang dijatuhkan, dan bagaimana hal itu berdampak pada pendidikan kewarganegaraan. Penelitian ini menggunakan pendekatan deskriptif analitis untuk memberikan gambaran lengkap tentang kasus ini dan bagaimana peristiwa tersebut mencerminkan krisis moralitas dan integritas di kalangan penegak hukum.

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.
