The Development of Children's Early Numeracy Skills in The Piaget’s Preoperational Stage
Full text linkEarly numeracy skills are crucial for young children's cognitive and mathematical development, particularly during the preoperational stage (ages 2-7), when they begin to develop symbolic thinking and foundational mathematical concepts. This study investigates the progression of early numeracy skills in two preschool-aged children (Child H and Child K), focusing on their ability to engage with numeracy concepts such as counting, cardinality, numeral identification, and number combination. Using a qualitative case study approach, the research observes the children's numeracy behaviors through assessments and direct observation during play-based learning activities. Findings reveal notable differences in the children’s numeracy development: Child H demonstrates stronger skills in one-to-one counting, subitizing, number ordering, and problem-solving, while Child K shows emerging abilities but struggles with tasks such as number comparison and number combination. These differences highlight the variability in the development of numeracy skills, with confident children progressing more rapidly in their understanding of numbers and relationships. The study emphasizes the importance of concrete, hands-on learning experiences in developing mathematical thinking, mainly through physical manipulatives and interactive, game-based activities. The results underscore the need for tailored learning experiences to support children in the preoperational stage, which has implications for early childhood educators in fostering a strong mathematical foundation

Learning Design of Quadratic Equation Using ICT to Understand the Concept and Reduce Math Anxiety
Full text linkQuadratic equations are essential material that students need to master. Based on several studies, many students have not mastered the material because they have not mastered the prerequisite skills and find solutions. This study aims to describe the learning design of quadratic equations using ICT, namely the Algebra Tile app, to understand the concept and reduce students' math anxiety regarding Cone of Experience Theory, Information Processing Theory, and Genesis Instrumentation Theory. The material is limited to quadratic equations with rational roots. The design of learning quadratic equations using ICT refers to three stages of development, namely: (1) analysis stage, (2) design stage, and (3) development stage. The results showed that the learning design was valid, practical, and effective. Using algebraic tile applets helped students factor in quadratic equations and lowered their anxiety during learning. Furthermore, the efforts made by the teacher by dividing students into several groups during learning, providing learning videos, ice breaking, and a short pause after conveying the concept can reduce students' anxiety

Full text linkAbstract The increasing global population growth poses serious challenges in meeting the world's food needs, and one promising solution is to increase productivity and efficiency in agriculture through Internet of Things (IoT) technology. In order to achieve this, this study aims to develop and implement an Internet of Things (IoT)-based automation system for indoor aeroponic farming, specifically designed to cultivate mustard flowers, utilizing advanced LED Grow Light technology for optimal growth conditions, a capacitive soil moisture sensor to detect uneven condensation of nutrients, and a pH sensor to maintain the balance of nutrient solution. The NodeMCU ESP32 microcontroller, alongside the Arduino platform, serves as the central control unit of the system, autonomously monitoring and regulating the growth environment. The findings demonstrate how effectively this technology can detect and adjust plant growth parameters, such as air temperature (99.24%), water temperature (98.63%), nutrient content (96.50%), water height (94.20%), and water pH (98.88%). In addition, the system successfully provides lighting using an L.E.D. Grow Light that is on for 12 hours every day, and effectively detects condensation unevenness, which then provides notifications via Telegram. The increased efficiency achieved by this system shows great potential in supporting efforts to fulfil global food needs through IoT technology.

Meta Analysis: Reciprocal Teaching Learning Model to Improve Mathematics Learning Outcomes
Full text linkThe success of an education is associated with the high and low learning outcomes that have been achieved. The results of mathematics learning are very important, because they measure whether the learning that has been carried out so far has been successful or not. One learning model to improve mathematics learning outcomes is the reciprocal teaching learning model. The aim of this research is to analyze articles on the topic of mathematics learning outcomes in the reciprocal teaching model. The method used in this research is the meta analysis method. The research obtained results that there were three articles with effect sizes in the medium category and three articles with effect sizes in the strong category. The average effect size value of the six articles analyzed was 1.27 in the strong category. So it shows that the reciprocal teaching learning model has a strong influence in improving students' mathematics learning outcomes. Apart from that, the results of hypothesis testing were carried out using the t test, namely t test = 10.89 > 1,968 = t table. This shows that the average mathematics learning outcomes of students using the reciprocal teaching learning model are better than the average mathematics learning outcomes of students using the conventional learning model
