Abstract

Abstract: The purpose of this study was to determine whether or not there was an effect of the STAD Type Cooperative Learning Model on Learning Outcomes of Primary Mathematics Circles for Class VIII Even Semester SMP Negeri 1 Padangan. The population of this study were all students of SMP Negeri 1 Padangan class VIII. The samples taken were three classes. The data collection technique used is the method used for data collection in this study by using the documentation method, and the test method in the form of multiple choice questions as many as 20 questions. The test instruments used were content validity, item validity, discriminatory power, level of difficulty, and reliability. The prerequisite test used is the normality test using the Lilliefors method and the homogeneity test using the F test. The data analysis technique used is the t test. The results of the calculation in the data analysis show that x = 81.6129 and x = 69.0625, s_1^2 = 132.286 and s_2^2 = 186.189, Fcount = 1.5102 > Ftable = 1.825 (Ho is accepted and the variance is homogeneous), it is obtained tcount = 4.0357 > ttable = 1.999 so Ho is rejected and H1 is accepted. even the 2017/2018 school year.Keywords: STAD; Math Learning Results

Abstract

Abstract: The purpose of this study was to determine the effect of the PBL (Problem Based Learning) model on the ability of Mathematical Literacy on the subject of Statistics for class XI TKR SMKN 3 Bojonegoro students. This type of research is a quasi-experimental research, because it is impossible in the study to control the relevant variables. This study used a posttest only control design. The population of all students of class XI TKR SMK Negeri 3. Cluster random sampling technique for sampling. The cluster random sampling technique is done by lottery. After the lottery, the results showed that class XI TKR 2 as the experimental class had 30 students and class XI TKR 1 as the control class had 30 students. Data collection techniques using interviews, tests and documentation. Before the questions are used, they are tested for validity, reliability, distinguishability, and level of difficulty. The data analysis technique used -t test. The results of the research. The t_count value obtained in the calculation using the Polled Variance formula is t_count = 2.0533, the significance level = 0.05 and the t_table price = 2.0017, so that the t_count> t_table value is obtained. Thus, it can be concluded that using the PBL (Problem Based Learning) model causes students to have better mathematical literacy skills than using the direct learning model on the subject of Statistics for class XI TKR SMKN 3 Bojonegoro students.

Abstract

This study aims (1) to create and develop teaching materials with an open ended approach in mathematics at MA Al-Khoiriyah Balan which can be used to build student learning independence. (2) to determine the feasibility and effectiveness of the developed teaching materials. This research includes research development (Research and Development). The model used in this research and development is the ADDIE development model. The research was conducted at MA Al-Khoiriyah Balen majoring in Mathematics and Natural Sciences involving 21 students aiming to find out the effectiveness of functional teaching materials, as well as 2 lecturers and 1 teacher as expert validators to determine the feasibility of teaching materials so that they can be used in learning. The results of the development of functional teaching materials are as follows: the results of the validation of media experts obtained an overall average of 75.4% in the "valid" category and the results of the validation of material experts consisted of two assessment aspects, namely the content aspect which received an overall average of 79 % and linguistic aspects that get an overall average of 77% in the "valid" category. The results of the study show that functional teaching materials with the ONDE (Open Ended) approach are feasible to use and effective in building student learning independence in MA Al-Khoiriyah Balen students Keywords: teaching materials; open ended approach; student learning independence; function material
