Abstract

Mathematics is closely related to science because both require the ability to analyze, think logically, and systematically to understand. This study explores students' level of abstraction thinking in understanding the concept of exponent numbers and its implementation in science. This research uses a qualitative approach. The subjects in this study were students of the master's program in basic education. The data collection techniques used were tests and interviews. The results showed differences in identifying exponent numbers in low and high abstraction level students. Low abstraction level students perform problem-solving stages, such as identifying and writing down every information listed in the problem, using mathematical symbolization, performing number operations according to problem understanding, and checking again. Meanwhile, high abstraction level students performed problem-solving stages, such as identifying every piece of information in the problem without writing it on the worksheet, not writing the results of their understanding explicitly on the worksheet, not writing explicitly the model to be used, performing number operations without paying attention to the type of number because they already understood and they made a conclusion. Both level students applied the concept of exponent numbers in science for writing units and density.

Abstract

One of the mathematics materials students considers difficult is integer material. This affects the results of AKM Numeracy, which is not optimal, especially in the number domain. This study aimed to develop a numeracy literacy-based mathematics test instrument on whole number material in grade V elementary school. This type of research is Research & Development with the development stages of the Thiagarajan 4D model (defining, designing, developing, and disseminating). The instruments developed include question grids as guidelines for making questions, questions and answer keys to test students' numeracy skills and scoring guidelines as a tool for giving student scores. The number of questions developed was three multiple-choice questions and seven complex multiple-choice questions. The principal and fifth-grade teacher validated this test instrument and obtained very valid results. The instrument was tested on fifth-grade students of SDN Kasembon 3 in the 2023/2024 school year and received the results of the item validity test getting a valid level on each item, the reliability test getting a high level, the differentiator test getting a sufficient and reasonable level, and the difficulty test getting an easy and moderate level. So, this numeracy literacy-based mathematics test instrument on integer material is feasible and can measure numeracy skills very well

Abstract

This study aims to test the effectiveness of the Project-Based Learning (PjBL) learning model that is integrated with digital teaching materials and computational thinking in improving the Habits of Mind of elementary school students in Malang Regency. The research approach used is quantitative with a pre-experiment type experimental design, using a one-group pretest-posttest design. The research instrument is in the form of pretest and posttest questions designed to measure the development of students' Habits of Mind before and after the application of the learning model. The results of data analysis showed a significant increase in posttest scores compared to pretests, with an average difference of 13.28 points and a significance value (Sig. 2-tailed) of 0.000. These findings indicate that the Project-Based Learning model that is integrated with digital teaching materials and computational thinking is effective in improving students' Habits of Mind. Thus, this model is recommended as an alternative learning strategy that is innovative and relevant to be applied at the elementary school level, especially in forming a critical, reflective, and adaptive mindset in students.
