Abstract

This study aims to determine whether there is a difference in the ability to understand students'concepts taught by using Contextual Teaching And Learning (CTL) learning model and studentstaught with guided invention learning model at MTs.S Al-Jihad Medan. This study was designedand implemented using a quasi-experimental method and involved a sample of 60 students. Thisstudy uses the instrument in the form of a description of pretest and posttest used to determinethe ability of understanding the concept of mathematics students. From the research result, itcan be found the postest average value 81,33 for experiment class A and 78,4 for experimentclass B. The data obtained are analyzed by using Chi-Square test, F test, and t test. Based onthe test, it can be concluded that there is a difference of students' concept comprehension abilitytaught by using Contextual Teaching And Learning (CTL) learning model and students taughtby Guided Discovery model at MTs.S Al-Jihad MedanT.A 2017/2018.

Abstract

Abstrak. Penelitian ini bertujuan untuk (1) mengetahui peningkatan hasil belajar matematika siswa dengan menggunakan model pembelajaran PBL (Problem Based Learning) pada materi Sistem Persamaan Linier Dua Variabel di kelas VIII SMP Negeri 1 Rantau Selatan.. Jenis penelitian ini adalah  penelitian  tindakan kelas (classroom  action  research). Subjek dalam penelitian ini adalah siswa kelas VIII. Penelitian ini adalah penelitian tindakan kelas yang dilaksanakan dalam 2 siklus yang masing-masing siklus dilaksanakan dalam 2 kali pertemuan. Subjek dalam penelitian ini adalah siswa kelas VIII-2  yang berjumlah 35 orang. Berdasarkan  Hasil analisis siklus I dari nilai Test Hasil Belajar I diperoleh nilai rata-ratanya 55,42. Sebanyak 10 siswa (28,57%) tuntas dalam belajar sedangkan 25 siswa (71,42%) tidak tuntas. Dan hasil analisis siklus II dari nilai Tes Hasil Belajar II nilai rata-ratanya 72,28. Sebanyak 31 siswa (88,57%) tuntas dalam belajar sedangkan 4 siswa (11,42 %) tidak tuntas dalam belajar.Ketuntasan belajar siswa secara klasikal dan individu mencapai 88,57% yang memperoleh nilai 65 dan siswa lainnya atau 11,42% memperoleh nilai < 65, maka pembelajaran ini dikatakan tuntas. Tingkat penguasaan siswa dari tes belajar II mencapai kriteria tinggi, maka pembelajaran ini dikatakan telah tercapai. Pelaksanaan pembelajaran berdasarkan hasil observasi untuk guru pada siklus I sebesar 2,23 meningkat pada siklus II menjadi 3,02. Berdasarkan hasil penelitian tersebut dapat disimpulkan bahwa Model PBL  dapat meningkatkan hasil belajar siswa pada materi sistem linier dua variabel di kelas VIII-2  SMP.Kata kunci : PBL, Hasil Belajar Matematika, SPLDVAbstrac. This study aims to determine the improvement of mathematics learning outcomes of students by using PBL (Problem Based Learning) model on the material of Two Variable Linear Equation System in class VIII SMP Negeri 1 Rantau Selatan. This type of research is a classroom action research. Subjects in this study were students of class VIII. This study is a classroom action research conducted in 2 cycles which each cycle is held in 2 meetings. Subjects in this study were students of class VIII-2 which amounted to 35 people. Based on the results of the analysis of the cycle I of the value of Test Results I obtained an average score of 55.42. A total of 10 students (28,57%) complete in learning while 25 students (71,42%) not complete. And the result of analysis of cycle II from test result of result of learning II average value 72,28. A total of 31 students (88,57%) complete in learning while 4 students (11,42%) not complete in learning. Student learning completeness in class and individual reach 88,57% which get value of 65 and other student or 11,42% get value <65, then this learning is said to be complete. The level of mastery of students from the test of learning II reaches a high criterion, then this learning is said to have been achieved. Implementation of learning based on observations for teachers in cycle I of 2.23 increased in cycle II to 3.02.

> ABSTRACTThis study aims to determine the ability of students' understanding of mathematicalconcepts by using Problem Posing approach is higher than Direct Instruction Learningin VIII class at Private Junior High School of Methodist Tanjung Morawa. This researchis a quasi-experimental research with pretest-posttes design.The population in this studyis all students of class VIII consisting of 3 classes, while the sample in this study werestudents of class VIII-1 (experimental class) as many as 31 people and class VIII-2(control class ) of 31 people. The research instrument in data collection is a test. Beforetesting the hypothesis first tested the normality of data by using Liliefors test andhomogeneity of data using F test. From the test it was obtained that the pretest results ofboth samples distributed normal and homogeneous, thus the authors can give treatmentto both samples. From the result of pretest-posttes data analysis using t-test at α = 0,05we get t_count> t_ (table) that is 1,955> 1,677 so that H_o is rejected and H_a accepted.So it can be concluded that the ability to comprehend the concept of mathematics studentsusing Problem Posing approach is higher than Direct Instruction Learning in VIII.Keywords: Posing problem, Understanding of mathematical conceptsABSTRAKPenelitian ini bertujuan untuk mengetahui kemampuan pemahaman konsep matematikasiswa dengan menggunakan pendekatan Problem Posin glebih tinggi daripada DirectInstruction Learning di kelas VIII SMP Swasta Methodist Tanjung Morawa.

This study aims to determine whether are differences in problem solving skills of mathematics students using cooperative learning type TAI and NHT in class VII SMP Negeri 3 Pulau Rakyat. This type of research is quasi experiment. The population in this study is all students of grade VII semester 2 SMP Negeri 3 Pulau Rakyat consisting of 5 classes with total 160 students and the sample of this study are VII-1 and VII-3 as many as 64 students. The required dara is obtained by using the students’ math problem solving test in the form of a description of 4 question. From the results of data analysis obtained the average test results of students mathematics problem solving abilities through cooperative learning type TAI is 27,28 with varians 2,65 and the average test result of students’ mathematics problem solving abilities through cooperative leraning type NHT is 22,25 with varians 3,28. To test hypothesis used t test, from the calculation results obtained tcount with the test reject Ho and accept Ha if tcount  1,6697 so it looks  that tcount is not reside in the Ho accetance area which means Ho rejected and Haaccepted or in other  words there are differences problem solving ability of mathematics students using cooperative learning type TAI and NHT in class VII SMP Negeri 3 Pulau Rakyat. Keywords: Mathematical Problem Solving Abilities, TAI, NHT

ABSTRACT This study aims to determine whether the mathematical communication skills of students who learn by using cooperative learning model Think Talk Write type is higher than the mathematical communication ability of students who learn by using cooperative learning model Think Pair Share type. This type of research is a quasi experiment. The population of this research is all students of class VII of SMP Negeri 3 Percut Sei Tuan. Research sampling was done by cluster sampling and many samples in this research consist of 2 classes, first class is called experimental class I and second class is called experiment class II. The instrument used in this research is a test of mathematical communication ability consisting of 4 items of description. From result of data processing obtained on result of posttest mean score of mathematical communication ability of student 13,4722 for experiment class I and 12,0556 for experiment class II. Based on hypothesis testing that is done by using t test with obtained. This shows that being out of acceptance then based on the test obtained that rejected so it can be stated that the mathematical communication skills of students who learn by using cooperative learning model Think Talk Write type higher than the mathematical communication skills of students who learn by using cooperative learning model type Think Pair Share at SMP Negeri 3 Percut Sei Tuan.
