碩士 === 國立臺中教育大學 === 數學教育學系在職進修教學碩士學位班 === 102 === The study was to explore the mathematical writing from the 1st graders in terms of their concepts of the time about date in order to understand and solve questions. The 22 objects of the study came from the school that the researcher works for.The study combined mathematics writings with the school curriculums of time and the date, used triangulation to explore developments of the students’ concepts of the time by collecting student’s learning sheets,activities,concept maps,post-tests and deferred tests.The study found fitst-graders understood the order, continuity, non-reversible and periodic characteristics of time from their mathematical writings. They could solve the questions by combining the above concepts with their daily-use languages. In the meantime, they used subtraction to solve the questions of duration.Furthermore, the study revealed that the students could blend the prior knowledge and new knowledge that made their concepts more solid and comprehensive.It effectively helped the teacher to know the conceptual development of the students. From the results of the post and delayed tests, the students had learning and were able to solve the daily problems. However, the concepts of duration were still difficult .
