Abstract

Research into the development of teaching materials in the form of interactive LKPD was motivated by students' lack of interest in working on mathematics problems other than those assigned by the lecturer. Therefore, they tend to be less able to solve a problem if given questions. With the LKPD, it is hoped that it will be able to train the development of cognitive aspects or all aspects of learning in the form of experimental guides or demonstrations. LKPD is a form of implementation by teachers who act as facilitators in learning. The application of LKPD can give students the opportunity to think actively and creatively to improve learning in achieving learning indicators and competencies. LKPD is given with the aim of actively involving students in learning activities, so that learning in the classroom is no longer teacher centered but student centered. For this reason, researchers use e-LKPD with the aim of making learning more fun and interactive. One of the advantages of e-LKPD is that it helps lecturers and students carry out learning independently at home because it can be accessed online without requiring face-to-face meetings. Apart from that, students can access text, image, audio and video content that cannot be contained in conventional LKPD. This research shows the following results: 1) the average validity given by media expert validators is 3.83 and material expert validators is 3.66, both of which are in the very valid category, 2) the practicality of the e-LKPD being developed is taken based on student response questionnaires. namely 92% which is in the very practical category, 3) the effectiveness of e-LKPD is obtained based on achieving classical completeness of 88.57% of students completing the material covered. given.

Abstract

This research aims to determine whether there is an influence of the TPS (Think Pairs Share) learning model on problem solving in fourth grade fraction material at SDN 89 Singkawang. The type of research used is quantitative research with a true experimental design method. The population in this study was 35 class IV students at SDN 89 Singkawang. Then samples were taken using a purposive sampling technique so that the sample used was 35 students consisting of class IV. The sample used in the research was carried out by selecting samples taking into account the students' cognitive results, so that researchers could produce class IV for the experimental class and control class. The prerequisite test carried out is a normality test using the Chi-square formula and a variance homogeneity test is carried out to see the similarity of the variants in the two groups. To test the first hypothesis, the Effect Size formula is used and to test the second hypothesis, the t-test formula is used. The results of the research show that: 1) The TPS (Think Pairs Share) learning model has an effect on problem solving abilities in class IV fraction material at SDN 89 Singkawang. This is shown from the calculation of the Effect Size value, which is 1,600, which is included in the high criteria. 2) There is a difference in problem solving abilities using the TPS (Think Pairs Share) model with the conventional model in class IV fraction material at SDN 89

Abstract

Multicollinearity is a problem that often arises in regression analysis. If the assumption of the absence of multicollinearity is not met, researchers will have difficulty in identifying independent variables that have a significant effect in the regression model. The presence of multicollinearity can cause the estimation of regression parameters in the Ordinary Least Square (OLS) method to be inefficient. To overcome this, the LASSO Regression method and the Principal Component Regression (PCR) method are used. The data used in this study are generation data derived from low (0,1-0,3), medium (0,4-0,6), and high (0,7-0,9) correlation levels with different sample sizes (n=20,40,120,200) from normal distribution with 30 and 60 independent variables. The performance of LASSO Regression method and Principal Component Regression (PCR) method is evaluated using Mean Square Error (MSE) value and coefficient of determination ( ) value. Based on this research, the LASSO Regression method has better efficiency than the Principal Component Regression (PCR) method because the LASSO Regression method obtains a smaller Mean Square Error (MSE) value and a higher coefficient of determination ( ) value than the Principal Component Regression (PCR) method.

Abstract

This research aims to examine the penalty methods used in linear optimization. The main objective is to identify the advantages and disadvantages of each penalty method, as well as determine the specific context in which each method is most effective. This research belongs to the literature research type. The study is conducted on prepared cases to obtain the optimal result of each penalty method. Penalty methods and barrier methods are interrelated in optimization, especially in handling problems with constraints. The penalty method is used to start the solution search, while the barrier method is applied at the final stage to refine the solution. This is because the penalty method is able to provide an initial solution quickly, which can then be refined using the barrier method to better approach the constraint boundary.

Abstract

This study explores the integration of the history of mathematics and geometric approaches in enhancing students' understanding of quadratic equations. The research indicates that students who engage in this learning process can establish connections between geometric manipulations and algebraic symbols used in quadratic equations. By converting geometric forms into algebraic expressions and vice versa, students gain a deeper understanding of concepts such as factorization and perfect square solutions. The integration of historical mathematics and geometric approaches proves to be effective in improving students' conceptual understanding and overcoming learning barriers. Visualizations, particularly through methods Geometry, allow students to build a more intuitive understanding of quadratic equations, thereby increasing their interest and motivation in learning
