Abstract

This study aims to improve the ability to understand and sequence number symbols in students with mild intellectual disabilities in Grade I at SLB Asuhan Kasih Kupang. The main problem found is that learning is still abstract, making it difficult for students to recognise and sequence the symbols for numbers 1–10. This study uses a classroom action research design based on the Kemmis and McTaggart model, which was implemented in two cycles. There were three students participating in this study. Data were collected through observation, tests, and documentation. The results showed a significant improvement from the pre-cycle to each action cycle. In cycle I, the students' abilities were still in the very low category. After using number cards that were presented in a concrete and interesting manner and repeated several times, there was an improvement in the students' ability to understand the symbols for numbers 1–10 and sequence them correctly. At the end of cycle II, all students achieved the predetermined success criteria with scores of RN (95), PB (95), and NF (90). These findings indicate that number card media effectively help students with mild intellectual disabilities process information more concretely and increase their focus and engagement during learning. Thus, number card media can be a relevant learning alternative to improve basic mathematical skills for students with mild intellectual disabilities

Abstract

Developing basic literacy skills in children with learning disabilities requires adaptive learning strategies based on concrete media. One of the main challenges is the students' limited ability to recognise and arrange letters systematically. This study aims to describe the process of using letter tiles, improvements in student learning outcomes, and the responses of teachers and parents to their implementation at the Bhakti Luhur Baumata Kupang Special School. The method used was classroom action research with a descriptive qualitative approach, involving one student with special needs. Data were collected through observation, tests, interviews, and documentation, then analysed through data reduction, data presentation, and conclusion drawing. The results of the study indicate that letter stencils are effective in improving the ability to recognise vowels and consonants, pronounce letters correctly, and arrange letters into simple syllables. Student learning scores improved to the good category, accompanied by positive responses from teachers and parents. These findings confirm that letter stencils are an adaptive and enjoyable learning medium that can increase student motivation and confidence

Abstract

Children with mild intellectual disabilities, with an intelligence level of around 50–70, require a more concrete learning approach in order to master basic skills, including counting abilities. Difficulty in understanding numbers 1–20 often becomes an obstacle in their cognitive development and academic readiness. This study aims to improve the counting skills of children with mild intellectual disabilities through the application of number card media at SLB Negeri Manekat Niki-niki. The method used is classroom action research, involving four students who experience difficulties in basic mathematics. Interventions are conducted through structured learning activities that include the introductory, core, and closing stages. Data collection techniques are carried out through observation and tests. All research data are analyzed descriptively to determine the improvement in students' achievement results. The research results show that number card media are effective in improving the ability to recognize numbers, understand number concepts, and perform simple arithmetic operations. These findings confirm that concrete-visual media can be an alternative learning strategy relevant for children with mild intellectual disabilities, while also providing practical implications for special education teachers.

Abstract

This study aims to examine the effectiveness of Braille counting boxes in improving the ability of visually impaired sixth-grade students at Kanatang State Special School to add numbers between 0 and 100. The background of this study stems from the low mathematics learning outcomes of visually impaired students due to the abstract nature of numerical concepts, which necessitates concrete and tactile learning media to aid understanding. The research used the Classroom Action Research (CAR) method with a single subject design and involved a sixth-grade visually impaired student, Evan Clief Kaka (ECK), with a minimum passing grade (KKM) of 75%. The results showed a clear improvement after the intervention using the Braille Counting Box. The student's initial ability in the pre-action was only 35%, then increased to 50% in the post-test of Cycle I, and reached 80% in the post-test of Cycle II, which exceeded the MCC. Observations also noted an increase in the student's fine motor skills and independence, from the adequate category in Cycle I to the good category in Cycle II. Based on these findings, it can be concluded that the Braille Counting Box is effective in improving the ability to add numbers 0–100 and helps blind sixth-grade students at Kanatang State Special School achieve learning completeness.

Abstract

The ability to recognize basic colors is an important cognitive aspect for children with mild intellectual disabilities, but they often face memory barriers and difficulties in distinguishing them. This study aims to examine the effectiveness of using colorful balls as a medium to improve the ability to recognize basic colors in second-grade children with mild intellectual disabilities at SLB Negeri Manekat Niki-Niki. The research method used is Classroom Action Research (CAR) carried out in two cycles, with a total of 3 students as research subjects. Data were collected through observation, interviews, tests, and documentation, and then analyzed descriptively. The research results indicate that the use of colorful ball media can improve students' ability to recognize basic colors. The students' average score increased from 40.50 (poor category) in cycle I to 80.85 (good category) in cycle II. This shows that colorful ball media are effective as an alternative learning tool to enhance the cognitive abilities of children with mild intellectual disabilities, particularly in recognizing basic colors. This study provides theoretical and practical implications for teachers, schools, and other researchers in developing innovative and effective teaching methods for children with special needs.
