Abstract

Listening skills are a vital foundation for language development, yet they are often overlooked in early grades, resulting in passive learners with limited vocabulary. This condition was also observed in 30 first-grade students at MIN 4 Solok. The study employed Classroom Action Research using the Kemmis & McTaggart model, applying the Numbered Heads Together (NHT) strategy in two cycles to enhance listening skills and vocabulary mastery. Data were collected through observation, performance tests, interviews, and documentation, then analyzed descriptively in both qualitative and quantitative ways. The findings indicate a significant improvement: student mastery increased from 33.3% in the pre-cycle to 60% in Cycle I and 86.7% in Cycle II. Beyond academic scores, students gained greater confidence, active participation, and the ability to apply new vocabulary in meaningful contexts. These results confirm that the NHT model is effective in fostering cooperative listening-based learning in early-grade classrooms.

Abstract

The fundamental issue in early-grade mathematics learning is the students' difficulty in understanding abstract number operations concepts. An initial study at MIN Kota Solok showed that 76.7% of first-grade students failed to solve contextual problems involving addition and subtraction within 1-20, indicating low mathematical problem-solving abilities. This study aims to improve the mathematical problem-solving ability of first-grade students at MIN Kota Solok through the implementation of Problem-Based Learning (PBL) assisted by manipulative media. This research is a Classroom Action Research (CAR) conducted in two cycles, following the Kemmis and McTaggart model. Each cycle consisted of planning, action, observation, and reflection. Data were collected through tests, observation, and documentation. The results showed a significant improvement. The classical mastery percentage increased from 23.3% (pre-cycle) to 63.3% in cycle I and 86.7% in cycle II. The average score also rose from 50.0 (pre-cycle) to 66.0 (cycle I) and 82.0 (cycle II). Observational data indicated an increase in student activity and engagement in the learning process. The integration of the PBL model with manipulative media is effective in enhancing first-grade students' mathematical problem-solving abilities.
