UPAYA MENINGKATKAN HASIL BELAJAR MELALUI PENDEKATAN TARL DALAM PEMBELAJARAN BAHASA INDONESIA KELAS XI-2 SMAN 14 MEDAN

Abstract

This study aims to improve student learning outcomes in Indonesian language instruction through the implementation of the Teaching at the Right Level (TaRL) approach in class XI-2 at SMAN 14 Medan. The main issue addressed is students’ low comprehension of the structure and language of scientific writing, which stems from varied learning abilities that are not adequately accommodated by conventional teaching methods. This research employed Classroom Action Research (CAR) conducted in two cycles, consisting of planning, action, observation, and reflection stages. Data were collected through a diagnostic test (pre-test), observations, and learning outcome assessments. In Cycle I, the learning focused on analyzing the structure of scientific texts, while in Cycle II, the focus shifted to the linguistic features of scientific texts on the theme of environmental conservation in North Sumatra. The findings showed that the TaRL approach significantly improved the students' average scores from 68.09 in the pre-test to 75.15 in Cycle I and 86.97 in Cycle II, with the learning mastery rate increasing from 55.9% to 100%. Beyond cognitive gains, a notable improvement in student learning attitudes was observed, particularly among students initially categorized as “emerging”. Based on these findings, it is concluded that the TaRL approach is effective for use in heterogeneous classrooms to enhance learning outcomes and active student participation.
