Analisis kemampuan pembuktian matematis parabola menggunakan guided learning berdasarkan tingkat resiliensi

One of the geometry materials at the high school level is a parabolic. The ability to prove parabolic formulas is needed by students majoring in Mathematics Education who will become mathematics teachers after graduating. Having an understanding of proof of the formula will make learning more meaningful. The purpose of this research is to find out a description of the proof of parabolic formula based on high, medium, and low resilience levels, so that various obstacles can be overcome early. This research is qualitative research. Data collection techniques used resilience questionnaires, test questions to prove the parabola formula, and interviews. The data analysis technique used data triangulation. The results showed that (1) there are three indicators in mathematical proof of parabolic mastered by students at high, medium, and low resilience levels, namely drawing the vertex, fixed point, and directrix line, determining the length of the two points, determining the results of the equation squared, (2) determining the coordinates of the vertex, fixed point, and the equations of the directrix mastered by students with a high level of resilience, but not yet mastered by students at moderate and low resilience levels, (3) determining two lines of the same length in the image according to the definition parabolic and determining the results of the multiplication distribution on addition and subtraction have been mastered by students at high and medium resilience levels, but not yet mastered by students at low resilience levels,

Eksperimen model pembelajaran MMP dan Problem Solving terhadap kemampuan pemecahan masalah siswa

The purpose of this study was to determine whether the mathematics problem-solving abilities of students who received the Missouri Mathematics Project (MMP) learning model were better than the mathematics problem-solving abilities of students who received the Problem Solving learning model. The research was conducted at MTs Al-Iman Bulus Purworejo class IX A and IX B. The research method used was a quasi-experimental design, which refers to the instrument of students' mathematical problem-solving abilities. The study population came from grade IX students, with a total of 401 students. The sampling technique was cluster random sampling. The prerequisite test of normality, homogeneity, and balance before treatment showed that the data were normally distributed, homogeneous, and balanced. The prerequisite test for normality and homogeneity of the data after treatment showed that the data were normally distributed and homogeneous. The hypothesis test calculation using the t-test obtained of 2,2431 and with α = 5% ( ) of 1,6667. Based on the hypothesis testing results, the value of then is rejected; this means that the problem-solving ability of students who receive the MMP learning model is better than students who receive the Problem Solving learning model.

Analisis kemampuan koneksi matematika dalam mengerjakan soal cerita

The purpose of this article is to describe the mathematical connection ability of students in working on stories on statistics material. This article uses aqualitative approach. The data collection was obtained from the method of documentation, tests, and interview. There are 2 students of class VIII semester II as subjects in this article. The analysis was obtained from the test results of students which consisted of 5 description questions and the results of interviews on 6 indicators of mathematicalconnection ability. The results of the study obtained that the twostudents were less capable of applyingmathematics in other fields of study or everyday life and the relationships between mathematical topics and between mathematics topics and topics outside mathematics. So it can be concluded that the two students have a poor mathematical connection ability in solving story problems on statistics material.
