Abstract

One of the important abilities in a person's cognitive is the ability of memory, one of which is short-term memory (STM). This study investigates the relationship between Short-Term Memory (STM) and math learning outcomes. The researcher conducts a literature review to gather information and then performs an experiment to measure STM in a class of grade X students in a private school in Bekasi City. The study discusses various information about STM and its connection to students' math learning outcomes. The researcher develops an instrument to measure memory span and administers a test to obtain STM scores, correlating with student learning outcomes using Pearson simple correlation analysis. The results reveal a very low correlation (r=0.104) between STM and grade X learning outcomes in this study. The study concludes that STM does not significantly impact students' learning outcomes since long-term memory is where learners store their general knowledge, school learnings, and personal memories. It suggests that students must review previously studied materials before being assessed to achieve optimal learning results. Other factors that affect learning outcomes include students' psychological factors like interest, intelligence, talent, motivation, and cognitive abilities.

Abstract

One of the abilities that students need to build when learning mathematics is problem solving ability, so that students can implement their mathematical knowledge. From the results of student tests in the previous year and exploring the problem, researchers found that the problem solving ability of students faced for Trigonometry material is analyzing problems, organizing ideas and solving problems. The purpose of this study is to describe how students' problem solving skills after experiencing learning with the Realistic Mathematics Education Approach (PMR) for Trigonometric Comparison material assisted by Geogebra. The research subjects were 31 grade X students in one of the private high schools in Bekasi city in 2024/2025. The data collection methods used were field notes, written tests, and interviews. The instrument validation technique used expert validation techniques, while to validate the data, triangulation techniques were used. The research results from the written test are as follows: (a) the most difficulties found for problems 1 and 2 were executing the plan to get a solution, and looking back at the solution process; (b) the most difficulties found for problem 3 were making a plan, executing the plan, and looking back at the solution process. From the interviews with five students, it was found that the most experienced difficulties were making a plan, carrying out the plan, and reviewing the solution process; (b) the most experienced difficulties for problem 3 were making a plan, carrying out the plan, and reviewing the solution process
