Abstract

Mathematics is the study of interconnected values and concepts. This study is motivated by the problems of students in learning mathematics unit length conversion material class IV MI Islamiyah, learning unit length conversion material unsatisfactory learning outcomes due to lack of learning media that can attract students' attention. The purpose of this study is to improve student learning outcomes using the demonstration method through rule conversion media in the material of converting units of length in class IV MI Islamiyah. This research is a Classroom Action Research consisting of 2 cycles. The research subjects were grade IV MI Islamiyah students totaling 15 students. This research data use formative tests and observation sheets. The analysis technique used is the quantitative descriptive analysis technique. The results showed an increase in observation of teacher activeness from cycle I to cycle II by 65% and 92% (an increase of 27%) and observation of student activeness by 46% and 89% (an increase of 27%). 43%), and the average student score was 71 (46%) to 81 (80%). Based on these results, it can be seen that the use of rule conversion media can improve the test scores of grade IV MI Islamiyah students on the material of length unit conversion.

Abstract

The purpose of this research is to improve or help students in mastering the understanding of fractional numbers, especially in addition and subtraction of fractional numbers through a cooperative model, namely the Rotating Trio Exchange (RTE) type. This research is a form of classroom action research with two cycles. The participants or research subjects were our grade V students of SD 95 Pekanbaru which amounted to 33 children. The data collection techniques are observation, interview, documentation, and test. The results of the data analysis were that there were only 14 students or equivalent to 42.43% of students who reached the KKM limit in the initial condition before the research was carried out which was then able to change in cycles 1 to 19 students or around 57.57% which then also rose to 23 students or equivalent to 69.7%. From this description, it can be concluded that the use of the RTE type is able to help students understand and even improve their understanding of the addition and subtraction of fractions. The observation results also illustrate that students' cooperation attitude and responsibility attitudes changed for the better as solid teamwork in the rotation occurred in accordance with the RTE-type learning steps.
