Abstract

This research aims at knowing that cooperative learning model type talking stick with discovery learning appoarch is more effective than conventional learning model toward the result of mathematics subject of the students grade VIII SMP Negeri 11 Yogyakarta. This research uses Pretest-Posttest Control Group Design. The research has two variables. The independent variable consists of cooperative learning model type talking stick with discovery learning approach and conventional learning model, and the dependent variable is result of mathematics subject. The population was all students grade VIII in SMP N 11 Yogyakarta consisting of 136 students in 4 classes. The research sample of two classes was taken by cluster random sampling technique. Data collection technique uses pretest and posttest. The data analysis uses t-test, in which it was previously tested using pre-requisite test, namely; normality test and homogenity test, and than compares testimated  with ttable, with df = n1 + n2 -2, and α = 5%. If testimated   ttable , then Ho is refused. This means that the average gain score of experiment class is better than the average gain score of control class.Based on the result of estimated gained-score it is known that the value of testimated = 2,351, whereas ttable = 1,671. Because testimated = 2,351 > ttable = 1,671, then Ho is refused. This means that the average gain score of experiment class is better than the average gain score of control class. Therefore, it can be concluded that cooperative learning model type talking stick with discovery learning appoarch is more effective than conventional learning model toward result of math subject of the students grade VIII SMP Negeri 11 Yogyakarta.

Abstract

The research purpose to describe of this study is to increase interest and achievement in mathematics learning models cooperative intergreted reading and composation (CIRC) `in class XI TR C SMK 1 Sedayu. The results showed after that application of models Cooperative Integrated Reading And Composition  Mathematic(CIRC), liveliness and learning mathematics achievement of students has increased. The percentage average student liveliness from 48,87% pre-term to the first term, and increased to 57,87% in the second term. Mathematics achievement of students also increased, the average value of 64,39 to 85,82 in the pre-term at the end of the first term, and increased again at the end of the second term to 89,30. While the percentage of completeness students (with KKM 70) also increased, namely the pre-term by 43,75% to 62,50% in the first term, increased again in the second term to be 81,25%. Models to increase liveliness in mathematics learning and achievement of students, it is suggested cooperative intergreted reading and composation (CIRC) that mathematics teachers can apply the learning model.

Abstract

The purpose of the study to describe the process of cooperative learning Thinking Aloud Pair Problem Solving (TAPPS) in order to increase learning activity and mathematics achievement of class VII A SMP Piri 1 Yogyakarta. This research was Classroom Action Research (CAR) conducted a minimum of two cycles. The subjects of this study were students of class VII A SMP Piri 1 Yogyakarta totaling 21 students. The object of this study were learning activity and mathematics achievement. The results showed that learning activity and mathematics achievement have increased. This is indicated by the average percentage of observation sheet result of student learning activity by 69,84% first cycle and 78,17% in the second cycle. Results of students mathematics learning achievement test, the average value of mathematics learning achievement at 53,38 pre-cycle, the first cycle increased to 68,89 and the second cycle increased to 75,66. Based on the results of the implementation of cooperative learning Thinking Aloud Pair Problem Solving (TAPPS) model can increased learning activity and mathematics achievement.

Abstract

the purpose of this research is to find out the correlation interest of study and facility to study with the prestation of mathematics learning. This research method was descriptive of correlation. The population in this research is grade XI IPS SMA N 1 Kasihan Bantul Yogyakarta  totaling 74 students, with a sample of 74 student. Analytical techniques multiple regression analysis with requirment of normality and linierity. Based on the results of the research, R = 0,739, meaning that there was a positive correlation interest of study and facility of study with the prestatiton of mathematics learning. 0,691, meaning that there was a positive correlation interest of study with the prestation of mathematics learning.0,449, meaning that there was a positive correlation facility to study with the prestation of mathematics learning.

Abstract

The aim of this research is to know the effectivity of using Think-Talk-Write (TTW) type in cooperative learning model in comparison with conventional learning model toward the mathematics learning achievement of VII grade students in SMP 3 Magelang in the year of 2013/2014. The populations in this research are the students of VIIA, VIIB, VIIC, VIID, VIIE, VIIF, VIIG, and VIIH of SMP 3 Magelang. The samples in this research are the students of VIIA and VIID. The technique to take sample used cluster random sampling technique and done by class lottery. The data is analyzed with one party t test that is right parties to examine the hypothesis. The significant level of one party t test is 5%. The prerequisite analysis which is normality and homogeneity has been done previously. Building on the prerequisite test of t test, it is known that the data is normal and homogeny. With the result of that, the hypothesis test by t test can be done. From the description of the learning achievement value, the average of class experiment value (  = 82,188) higher that control class value (  = 76,25). The result of t test shows that tcount > ttabel (2,060 > 1,645) which is mean that H0 is refused and Ha is accepted. The conclusion of this research is mathematics learning using Think-Talk-Write (TTW) type in cooperative learning model is more effective than convensional learning model toward the mathematics learning achievement of VII grade students in SMP 3 Magelang in the year of 2013/2014.
