cial role in developing students’ logical, critical, and systematic thinking skills; therefore, successful mathematics learning constitutes an essential component of vocational education. The research problem focused on the influence of learning interest and self-confidence on the mathematical cognitive learning outcomes of eleventh-grade students at SMK Negeri 7 Kabupaten Tangerang. The study employed a quantitative approach with a correlational survey design. The research sample consisted of 129 students selected through cluster sampling techniques. Data were collected through Likert-scale questionnaires and documentation of students’ mathematics scores. Data analysis was conducted using descriptive statistics, Pearson correlation, and multiple linear regression with the assistance of SPSS software. The findings revealed that learning interest did not have a significant effect on mathematics learning outcomes, contributing only 1.1%, whereas self-confidence had a significant effect with a contribution of 10.8%. Simultaneous testing demonstrated that learning interest and self-confidence collectively exerted a significant influence on mathematics learning outcomes with a contribution of 13.8%. The findings indicate that self-confidence is a more dominant affective factor than learning interest in improving the mathematical cognitive learning outcomes of vocational high school students. The novelty of this study lies in the finding that the vocational practice-oriented characteristics of vocational high school students cause learning interest not to directly influence mathematics learning outcomes, while self-confidence emerges as a more determining factor in students’ academic achievement. The results of this study are expected to serve as a foundation for developing mathematics learning strategies that are more oriented toward strengthening students’ psychological aspects.

Then triagulation and validity are carried out. The group studied was Group A (ages 4-5 years) totaling 14 students. Data was collected from the results of observation sheets and field notes.The results showed that the cognitive development of group A PAUD KIA-KIRA in adding up with the numbers carriage game at the stage of development as expected (BSH) but on the indicator symbol of numbers at the stage began to develop (MB). Factors that support the implementation of the number car play activities, namely students who are enthusiastic to play even though there are some who are not familiar with numbers and homeroom teacher support is always helpful while the inhibiting factor is the cognitive ability to read the symbols of student numbers is still lacking, because the media at school is lacking inadequate as well as the lack of creativities educator makes educational props tools (APE).
Abstract:This research examines the application of ethnomathematics in coin exchange activities at Sarwono Market, which is related to learning arithmetic operations, with the aim of understanding how everyday practices in market…
transactions can serve as a medium for learning mathematics. The method used in this study is a qualitative approach with an ethnographic perspective, allowing the researcher to observe and understand phenomena within a broader social context. Data collection was carried out through interviews with traders and market visitors, direct observation of the coin exchange activities, and documentation of activities related to these transactions. The collected data were then analyzed using three main stages: data reduction, data presentation, and conclusion drawing. The results of the study show that the practice of coin exchange not only facilitates transactions in the market but also serves as a medium for applying arithmetic operations in everyday life. This activity encourages the development of logical thinking skills, such as addition, subtraction, multiplication, and division, which are frequently used in the bargaining process or in determining the price of goods. Furthermore, coin exchange helps maintain price stability and increases transaction efficiency in the market by reducing dependence on paper money, which is often difficult to divide accurately. Thus, the study concludes that the application of ethnomathematics in coin exchange activities at Sarwono Market provides dual benefits, both in the economic context and in mathematics education.
