Abstract

This classroom action research aims to improve the mastery of human body part vocabulary among four mild intellectually disabled students in Class III at SLB Negeri Kota Radja Kupang, who previously experienced difficulties in recognizing, naming, pointing out, and matching this basic vocabulary. The research subjects consisted of 4 students (2 males and 2 females). The method used is descriptive quantitative Classroom Action Research (CAR) with the Kemmis and Mc Taggart model, which includes planning, acting, observing, and reflecting. The intervention medium used was a poster medium, chosen for its ability to present information visually, simply, clearly, and to capture the attention of mild intellectually disabled children. The study was conducted in two cycles. The results of the data analysis show a significant increase. The students' average scores in the pre-action (pre-test) were in the poor and sufficient categories, then increased in Cycle I (post-test I), and reached a maximum improvement in Cycle II (post-test II) with a very good category. The conclusion of this study is that the use of the poster medium is effective and can enhance the mastery of human body part vocabulary in mild intellectually disabled children at SLB Negeri Kota Radja Kupang

Abstract

The background of this study is that students with mild intellectual disabilities still experience difficulties in recognizing number symbols 1-10. Although they have a normal age, students with intellectual disabilities have a mental age below their actual age, so learning media tailored to their characteristics and mental age is needed in learning. This study aims to improve the ability to recognize number symbols 1-10 through the use of audiovisual media. The method used is Classroom Action Research (CAR) with a quantitative descriptive approach based on Kurt Lewin's model, which includes four stages: planning, action, observation, and reflection. The research subjects were 4 students with mild intellectual disabilities in Grade III at SDLB Negeri Kota Radja Kupang. Data were collected through student observation sheets and student learning outcome tests. The research results show an increase in the ability to recognize number symbols from an average of 50% in Cycle I to 75% in Cycle II. Thus, it can be concluded that the use of audiovisual media is proven effective in improving the ability to recognize number symbols 1-10 for students with mild intellectual disabilities in grade III at SLB Negeri Kota Radja Kupang
