Abstract

This research is a descriptive research that aims to determine the quality of the items in the mathematics subject subject Geometry students at SDN 012 Tambak. The subjects in this study were practice questions in class V mathematics. The data from this research were obtained by collecting data in the form of daily math practice questions and answer sheets for class V students. The data analysis technique was quantitative descriptive data analysis. Based on the results of data analysis, in terms of content validity it is a valid item because it has rcount greater than rtabel at a significant level of 5%, in terms of overall reliability it is reliable with a distribution of 4 items of moderate reliability and 1 item of high reliability, in terms of difficulty level has a disproportionate distribution of difficulty level comparisons because there are more easy questions than moderate questions and there are no difficult items so that they are not in accordance with the comparison between easy-medium-difficult questions, and in terms of discriminating power most of them have discriminating power very good item.

Abstract

This study aimed to improve mathematics learning outcomes of fifth grade students at SDN 012 Tambak Kecamatan Langgam through the implementation of the Project Based Learning (PjBL) model. This research used Classroom Action Research (CAR) consisting of two cycles, where each cycle included planning, implementation, observation, and reflection stages. The subjects of this study were 16 fifth grade students consisting of 7 male students and 9 female students. Data collection techniques used were observation, tests, project assessment, and documentation. The results showed that the implementation of the Project Based Learning model was able to improve student learning outcomes and learning activities. Student learning completeness increased from 56% before the action to 75% in cycle I and increased again to 87.5% in cycle II. The average N-Gain score in cycle I was 0.455 with moderate criteria, while in cycle II it increased to high criteria. Student learning activities also increased in every cycle because students were actively involved in project activities, group discussions, and problem solving related to real life. Thus, the implementation of the Project Based Learning model can improve mathematics learning outcomes of fifth grade students at SDN 012 Tambak Kecamatan Langgam.
