Abstract

Time and elapsed time are concepts that are applicable in everyday life and thus directly affect students" lives. This is because students study the concepts in the lower grades of elementary school. Unlike other aspects of measurement, time is characterized by continuous flow and it uses a number system that is unfamiliar to students such as base-12 and 60 system. With such specificity, lower grade students may have difficulty in understanding time and elapsed time. In this respect, this study analyzed the concepts of time and elapsed time in the 2015 revised mathematics curriculum and textbooks and examined 108 second-grade elementary school students" responses. The results show that students are struggling to grasp these concepts. To be specific, many students had difficulty recognizing the movement of the minute and the hour hand over time. Moreover, they also had difficulty finding the elapsed time using the time band. This study provides guidance on how to teach time and elapsed time when learning occurs in the classroom.
