Abstract

Tujuan dari penelitian ini adalah untuk mengetahui apakah terdapat perbedaan efektivitas model pembelajaran Problem Based Learning dan Problem Solving terhadap kemampuan tingkat berpikir kritis siswa pada pembelajaran matematika SD kelas 5. Penelitian yang digunakan adalah penelitian eksperimen quasi, sempel yang akan digunakan pada penelitian ini sebanyak 57 siswa yang dibagi menjadi 2 kelas yaitu 26 siswa dari SD Marsudirini 77 dan 31 siswa dari SD Marsudirini 78. Penelitian ini dapat dilihat keberhasilannya berdasarkan hasil analisis uji N-Gain untuk mengetahui keefektivitasan, eksperimen 1 menggunakan model pembelajaran Problem Based Learning sedangkan eksperimen 2 menggunakan model pembelajaran Problem Solving. Hasil uji N-Gain menunjukan kelas eksperimen 1 sebesar 0.61 dan kelas eksperimen 2 sebesar 0.52. dari hasil penelitian dapat dikatakan H0 ditolak dan Ha diterima. Kesimpulannya adalah terdapat peningkatan kemampuan berpikir kritis antara siswa kelas 5 SD marsudirini 77 menggunakan model pembelajaran Problem Based Learning dan siswa kelas 5 SD Marsudirini 78 menggunakan model pembelajaran Problem Solving. Dari hasil penelitian ini maka peneliti merekomendasikan pembelajaran dengan model Problem Based Learning dapat meningkatkan kemampuan berpikir kritis siswa, sebaliknya dijadikan alternatif dalam kegiatan pembelajaran matematika pada materi volume bangun kubus dan balok.

Abstract

Leadership plays a strategic role in determining the success of educational organizations. The differences between transformational and transactional leadership have become an important area of study in understanding leadership effectiveness in schools. This study aims to analyze the conceptual differences between transformational and transactional leadership and to examine their relevance within the context of educational organizations. This research employs a descriptive qualitative approach using a literature review method. Data were collected through an in-depth review of books, scholarly journals, and previous research related to leadership theories. The data were analyzed using content analysis techniques to identify the characteristics, strengths, and implications of both leadership styles. The findings indicate that transformational leadership is more relevant to the educational context because it enhances motivation, commitment, innovation, and collaborative culture. Meanwhile, transactional leadership remains necessary, particularly in administrative management and short-term goal achievement. Therefore, a proportional integration of both approaches is considered an effective strategy to improve performance and the overall quality of educational organizations.
