Kemampuan Pemecahan Masalah Matematika Pada Soal Open Ended Materi Lingkaran Berdasarkan Kemampuan Awal Matematika Siswa

The research was aims to describe the problem solving in mathematics ability on open ended with circle material based on the early mathematical ability of the students at 9th grade junior high school 8 mataram. The type of the research is a descriptive study with quantitative approach. The research subject are 28 students which selected with purposive sampling. The subject is grouped according to early abilities of high, moderate, and low mathematics using the midterms. The data-collection method used is an open-ended problem-solving test on a loop of 2 terms of description and interview methods. The results were analyzed based on an indicator of problem solving capability according to Polya. Based on the data analysis, student problem solving capabilities with advanced mathematical abilities fall into good category, averaged 79.69. The student problem-solving capability with the early math skills is in good category, with an average score of 77.50. Student problem solving with early abilities of low math falls in the less category, with an average value of 48.30. The students with advanced math skills and are filling indicators of understanding the problem, planning a settlement and carrying out a completion plan, but have not yet met the checking indicator.

Systematic Modeling and Prompting to Teach Math Skills to Preschoolers With Disabilities

Early math skills predict later academic achievement and are of critical importance in preschool. There also are discrepancies in early math skills of preschoolers with disabilities compared with their typically developing peers. We used an experimental single-case research design, multiple probe across skills, to investigate the effectiveness of systematic modeling with mathematical language and a prompting procedure on increasing the early math skills of two preschoolers with disabilities or delays. A functional relation was observed for one participant. Equivocal findings may be due to the following: (a) challenges in assessing early math skills, which may have affected the identification of appropriate target skills, and (b) the involvement of multiple developmental domains in performing math skills, which may have affected the demonstration of target behaviors for the participant with significant fine motor and language delays.

The Effectiveness of Discovery and Inquiry Learning Strategies in Improving Students’ Early Math Skills

The study aimed to find out the effectiveness of discovery and inquiry learning strategies on the efforts of improving the early math skills of students in kindergartens in West Java Province, Indonesia. This is experimental research. The sampling method was done by multi-stage random sampling with probability sampling and it obtained 72 samples of kindergarten students consisting of 36 children from kindergartens in Bandung, West Java who were treated by discovery learning strategy and 36 children from the kindergartens in West Bandung Regency who was treated using inquiry learning strategy. Data were obtained using a checklist of observation sheets for early math skills of kindergarten children. Data analysis used a quantitative descriptive with a t-test. The findings of the study indicate that discovery-learning strategy is better than inquiry learning strategy in improving early math skills of kindergarten students. It is evidenced by the results showing that the average score of group with discovery learning strategy was 111.63 and the average score of group n using inquiry learning strategy was 101.96 with the result of t-count of 5.551 at the 0.05 level of significance. The conclusion of this research there were differences in early math skills between groups of children with discovery learning strategy and those with the inquiry learning strategy. From the results of data processing and discussion of the study, it was concluded that discovery learning strategy was better than inquiry learning strategy in increasing the score of early math skills of kindergarten children.

Mathematical Abilities of Preschool Children

Regardless of the fact that people are born with innate sense of number, mathematical thinking requires certain intellectual effort for which many children are not ready. While children investigate and discover new issues in everyday life, they meet the world of mathematics although they are not aware of it. As mathematics is becoming more and more important in today’s age of technology, it is very important that children are introduced to the spells of mathematics before they start attending school, and to continue to learn mathematics with that knowledge throughout school education. As well as reading, mathematics is a subject necessary for adequate functioning in society. What is more, mathematics is a subject that develops logical thinking and perception, thus mathematical teaching of children ought to be on more accessible level than it is currently. Parents and educators have access to various games and activities that involve children into mathematical thinking and creative resolving, which develops their self-confidence.Through the research that has been conducted with both preschool and primary school children using various mathematical examples appropriate for their age, it has been found out that the children of younger age have early math skills, whereas, regarding primary school children, their later math achievement is fading over time or their conclusions are grounded upon the “expected”. The traditional way of teaching mathematics and extensive material can cause poor mathematical achievement and cause a well-known fear of mathematics.

Contributions of Classroom Engagement and Exposure to Math Content on Preschoolers' Math Performance

Children's early math skills are one of the strongest predictors of later academic success, yet many preschools dedicate relatively minimal time to fostering math skill development. Children from socioeconomically disadvantaged backgrounds tend to enter school with weaker math skills than peers and continue to lag behind more affluent peers throughout elementary and secondary school. The current study a) explored the amount of exposure to math content that children receive in preschool (both observed and teacher-reported), and b) examined children's engagement with tasks, the quantity of exposure to math content, and the quality of instructional support as potential factors that may contribute to changes in children's math performance across the preschool year. The sample consisted of 380 preschool children from primarily low-income families. Controlling for child characteristics (e.g., sex, age, race, SES) and classroom factors (e.g., teacher education, years of teaching experience), children's engagement with tasks emerged as a strong predictor of positive changes in math performance across the preschool year. Independently, neither exposure to math content nor instructional support significantly predicted changes in children's math performance. However, the pairing of high-quantity exposure to math content and high-quality instructional support was associated with significant positive changes in children's math performance across the preschool year.
