Abstract

Observations conducted by researchers in one of class VII showed that the ability of students' understanding in the class is still minus. Whereas in KTSP 2013 mentioned that mathematical understanding is one of the basic competencies that must be owned and developed by students in learning mathematics. Based on the problem, the research was conducted by implementing constructivism model of learning in mathematics learning. Constructivism is one of the learning model where the students are actively mentally build their own knowledge based on the cognitive structure they have. This study is a classroom action research (PTK) carried out at SMPN 1 Lebakwangi. To obtain data in this study, the instruments used are the ability of comprehension test, observation sheet and student response questionnaire. Tests are tested with validity, reliability of difficulty levels and distinguishing power. The collected data is analyzed descriptively and quantitatively. Through the test obtained at each end of the cycle obtained the results of cycle I 45.75%, cycle II 65, 71%, and cycle III 85, 71%. From the results of this study also shows that learning mathematics with constructivism learning model can improve students' understanding ability. The best improvement is achieved on the aspect of the ability to transform a form of representation to another and the ability to recognize the various meanings and interpretations of concepts. This is seen from the calculation of the gain index is 0.29 with the medium category. Besides from result of questionnaire of student response showed positive response from student at learning by using constructivism learning model. This is seen from the results of the questionnaire calculation with the majority of students answered the response agreed 46, 38%.

Abstract

Student problem solving on learning mathematics in Class X SMK YAMSIK Kuningan is still low. This is because the implementation of conventional learning model that less develop the ability to learn and build individuals. Conventional learning tends to minimize student involvement so teachers seem to be more active. The habit of being passive in the learning process can cause most students to be afraid and embarrassed to ask the teacher about the less interesting material. One of the learning models tried through this research is the Make A Match learning model. The purpose of this research is to know the effectiveness of Make A Match method in learning mathematics. The population of this research is students of class X SMK YAMSIK Kuningan. Sampling in this research using Cluster Random Sampling technique with M-G pattern that is using balancing technique average pretest value of control group and experiment group. There are 2 (two) variables in this research, namely: (1) Make A Match Learning Model with conventional learning model, and (2) Problem solving student. Data collection techniques used are documentation, tests, and questionnaires. Instrument test results (validity test, level of difficulty, distinguishing power) consisting of 5 items and used for pret test and post test are 5 items. Based on the results of instrument reliability test for pretest, postes, and questionnaires obtained the whole instrument is reliable and can be used for data collection. The test result difference of two average pret test (t is in the acceptance area of ​​Ho) concluded there is no difference between the experimental group and the control group. Test of difference of post experiment group average and control group was found that experimental group was better than control group. Average estimation in control group with mean of student learning result 35.92 meanwhile experimental group average estimation with mean of result of learning 37.94 mean control group result of problem solving at learning of mathematics lower than experiment group, hence there is influence between effectiveness The model of Make A Match learning in mathematics learning in grade X students of SMK YAMSIK Kuningan. Based on the results of the study concluded that learning by using Make A Match model socialized and used as an alternative in learning mathematics in school. In addition to further research as the development of other research. Based on the results of the study it is suggested that the application of Make A Match learning model is socialized and used as an alternative in learning mathematics in schools to improve student learning outcomes. In addition, in the application of this model a teacher should always keep an eye on the class to motivate students' activeness and provide individual and group guidance. Further research needs to be done as self-development so as to develop research in a wider scope.

Abstract

the application of the method of Experiential Learning to increased Ability of JUNIOR HIGH SCHOOL students ' Mathematical Connections. This research aims to study the mathematical connection capacity of students who get the experiential learning with learning methods that get the conventional learning. This research is a research quasi experimental design. The results of the initial test data analysis retrieved tarithmetic t = -1.49 and ttabbel = 2.0252. because -2.0252 < -1.49 < 2,0252 or -ttabble < tarithmetic < ttabble, so the ability of mathematical connections both classes before the second treatment given in the same class are the same. While the analysis of tests late retrieved Uarithmetic = 226.5 and Utabbel are U(20)(20) = 138, because 226.5 > 138 or Uarithmetic > Utabble percentage, and average student response towards the learning of 33.2% this means that almost half of the students give experential learning method in response to learning in mathematics. A comparative analysis of the average score gains with N-Test-U earned Uarithmetic = 410 and U of the table is U(20)(20) = 138. Because Uarithmetic > Utabble or 410 > 138, then there is an increased ability of mathematical connection that uses the experiential learning learning better from the ability of mathematical connections that use conventional learning
