Abstract

This study aimed to determine the effectiveness of Problem Based Learning with MURDER strategy on students mathematical concept understanding ability in SMP Negeri 2 Sokaraja Academic Year 2018/2019. The method used was experimental research. Population in the study were the eighth-grade students of SMP Negeri 2 Sokaraja. The sampling was done by cluster random sampling technique; class VIII A as an experimental class treated by using Problem Based Learning with MURDER strategy and class VIII B as a class controls that used conventional learning. That instrument used was a post test problem that measures the ability to understand mathematical concepts. Based on the result of the t-test analysis with the help of SPSS 25.0, the Sig (2-tailed) = 0.015. Because it uses the right-side test, the Sig (2tailed) value is divided by 2 so that it gets 0.0075.With α = 0.05 then the value of Sig (2-tailed) meant that Ho rejected. This meant that the ability of students to understand mathematical concepts who were exposed by Problem Based Learning with MURDER strategy were more improved from those who only follow conventional learning. Therefore, it could be concluded that Problem Based Learning with MURDER strategy affected the mathematical concept of understanding ability.

Abstract

Student learning outcomes are a measure of student success in the learning process in class, and this study aims to determine the quality of student learning outcomes and aspects that affect mathematics learning outcomes in the comparison of trigonometry in a right triangle based on cognitive shutter at SMK Negeri 1 Maumere. Type of qualitative research with qualitative descriptive methods. Research subjects were students of class X DPIB-2 with a total of 34 people. This study uses data collection techniques by giving test questions and interviews. The analysis technique used in this research is descriptive qualitative data reduction, data display, and verification. The results of this study indicate that the learning outcomes of students with a low criterion are sufficient, the criteria are very large in number, the criteria for high are many, very high criteria the number is lacking. While the aspects affecting student learning outcomes are internal aspects and external aspects, internal aspects include students lack of interest in learning, students lack of understanding, memory and numeracy skills, while the external aspect includes family attention and support for students to repeat the material given by the teacher at home.

Abstract

ABSTRACT: This study aims to determine the effect of learning model learning cycle and direct learning and mathematical belief in the ability of mathematical communications with quasi-experimental method and 2 x 2 factorial design treatment by level. Retrieving data using mathematical communication test instruments and mathematical belief questionnaire. The study population was the eighth grades students of SMPN in Tangerang on the Academic Year 2014/2015. Samples were taken by multistage random sampling technique. Analysis techniques using two-way ANOVA. The results showed that: 1) The ability to communicate mathematical students treated learning model learning cycle is higher than the direct learning, 2) There is an interaction effect between learning model belief mathematics to mathematical communication, 3) ability to communicate mathematical students treated learning model of learning cycle is higher compared to the treated directly on the learning group of students who have high math belief, 4) There is no difference in the ability of communication in the group of students who have low math belief.

Abstract

This research aimed to describe the mathematic conceptual understanding skills based on the expertise competency of grade X students of SMK Negeri 3 Purwokerto. This research applied the descriptive qualitative method. The sample was collected through the purposive sampling technique. This research collected two subjects from each of high and low achieving category in each expertise competency. The categories of high and low achieving students were based on the minimum required score. The data were collected through a test of mathematics conceptual understanding skills and interviews. The data were validated using the triangulation technique. The results of the research showed that (1) students of hotel accommodation department had a better mathematics conceptual understanding skill than students of the catering management department. It happened because the category of high achieving students of accommodation department fulfilled all indicators of mathematics conceptual understanding skills and the category of low achieving students of accommodation department only fulfilled the indicators of giving examples and non-examples from the concept being learned. (2) Students of catering management department had a better mathematic conceptual understanding skill than students of the fashion design department. It happened because the category of high achieving students of catering management department did not fulfill one indicator of presenting the concept in some forms of mathematic representations and the category of low achieving students of catering management department did not master all of the indicators. (3) The category of high achieving students of the fashion design department mastered all indicators of mathematics conceptual understanding skills of giving examples and non-examplesform the concept being learned and presenting the concept in some forms of mathematic representation. Meanwhile, the category of low achieving students of the fashion design department only mastered the indicator of applying concept or algorithm to problem-solving.

Abstract

This study aims to describe the understanding of geometry based on the level of Van Hiele in terms of spatial intelligence in class X MA Al Hidayah 1 Purwareja Klampo. In the study divided into 3 groups: students who have high, low and medium spatial intelligence. The instruments used to collect data are tests, interviews, and documentation. The validation test used is technical triangulation, comparing the test results and the results of student interviews. The results of this study indicate that: 1) students who have high spatial intelligence are able to reach the level of the third level of van hiele (Understanding Deduction). 2) students who have spatial intelligence are able to reach the level of the second level van hiele (Informal Deduction). 3) students who have low spatial intelligence are able to reach evel van hiele stage 1 (Analysis).
