ANALISIS KEMAMPUAN LITERASI DAN PEMECAHAN MASALAH MATEMATIS BERBASIS INQUIRY DALAM KURIKULUM INTERNATIONAL BACCALAUREATE PADA JENJANG PRIMARY YEARS PROGRAMME

Abstract

This study aims to comprehensively analyze the enhancement of students’

mathematical literacy and problem-solving abilities through inquiry-based learning

within the framework of the International Baccalaureate (IB) Primary Years

Programme (PYP) at SD Al Firdaus Surakarta. The research uses a descriptive

qualitative approach with a case study design, involving one mathematics teacher

and twenty-one fifth-grade students selected through purposive sampling. Data

were collected through participatory observation, semi-structured interviews, and

document analysis, and validated by triangulating sources and methods. The

results indicate that inquiry-based learning implemented through the stages of

tuning in, finding out, sorting out, going further, and reflecting encourages active

participation, conceptual understanding, and students’ reflective thinking in

mathematics learning. Students demonstrate improvement in mathematical

literacy, specifically in the aspects of interpretation, representation, and reflection,

as well as in problem-solving abilities according to the four Polya stages:

understanding the problem, devising a plan, carrying out the solution, and looking

back. The teacher acts as a facilitator, guiding students’ thinking processes

through reflective questions and connecting concepts to real-life contexts and local

Islamic values. Despite challenges such as varying numerical abilities and the

need for additional time, adaptive strategies, including guided inquiry and

differentiated support, have been employed. The study demonstrates that inquiry-

based learning enhances logical reasoning, fosters metacognitive awareness, and

promotes contextual, reflective, and student-centered mathematics learning by

integrating global IB principles and local Islamic values as a holistic primary school

learning model.
