Participation is an important factor in achieving maximum learning in achieving learning goals. However, the level of student participation in learning is still relatively low. Therefore, efforts need to be made in the form of innovation in learning to increase student participation in learning, such as implementing LSLC based on the Jigsaw learning model. This research is a descriptive study with a sample of class XI IPS 1 SMA Adabiah 2 Padang. This research aims to see the impact of LSLC on student participation in learning using the Jigsaw learning model. Based on the results of data analysis, it was found that for each meeting there was a significant increase in student participation. So it can be concluded that learning using LSLC and the Jigsaw learning model has a positive impact on student participation in learning.

The preliminary exam results indicated that the 11th grade students at SMAN 3 Padang exhibited a comparatively low level of proficiency in mathematical problem-solving skills across all indicators. This is a result of insufficient engagement in the learning process. Consequently, an investigation was carried out utilising the Discovery Learning (DL) approach to enhance this capability. The methodology employed was a Quasi Experiment with an appropriate study design. Design utilising a posttest only control group that is not equal. Upon doing a t-test on the data from the sample class, with a significance threshold of α = 0.05, a P-value of 0.001 was achieved. This outcome signifies the dismissal of the null hypothesis (H0). These findings suggest that students using the DL model exhibit superior aptitude compared to those using the direct learning model in class XI at SMAN 3 Padang.Keywords– Mathematical problem solving abilities, Discovery Learning

Mathematics Learning Outcomes can serve as a measure of the effectiveness of a learning process. Nevertheless, the academic achievements in mathematics among the twelfth-grade science students at SMAN 12 Padang remain subpar. Passive classroom learning styles, which minimise student participation, are the main cause of this problem. A better learning approach is needed to improve student achievement. This research implemented the TSTS cooperative learning model. This research investigates whether the implementation of TSTS can improve the learning outcomes of students in class XII SMAN 1 Padang compared to traditional learning methods. In this research, a quasi-experimental non-equivalent control group design was implemented. The researchers found that the mathematics learning outcomes of students of class XII MIPA SMAN 12 Padang were better through TSTS model compared to direct learning model.Keywords– learning outcomes, Two Stay Two Stray

Math learning is often considered difficult by students, this requires the creativity of math teachers to innovate, one of which is by using interactive learning media such as Matific. The purpose of this study was to determine whether or not the use of Matific interactive game media was effective in improving the learning outcomes of seventh grade mathematics students at SMP Negeri 7 Padang on integer material. This study uses a qualitative method by giving a questionnaire. The results of the research on the use of interactive game media Matific has been running effectively in learning mathematics, especially integers and is able to improve student learning outcomes. This is evidenced by the percentage of student questionnaire assessment results of 88.45% which means that Matific games are very effective as interactive learning media. This research contributes to the field of education in developing mathematics skills, increasing student engagement, and reducing student anxiety through educational games that utilize technology in the teaching and learning process. Student involvement in the mathematics learning process is related to increased student learning outcomes. For this reason, it is hoped that mathematics will no longer be considered a difficult lesson by students

Literacy and numeracy are the abilities of students to use basic mathematics in solving daily life problems, and students should have it. Various studies have shown that Indonesian students' literacy and numeracy skills still need to improve. One of the solutions to this problem is RME, and one of the components that influence this skill is teachers as a facilitator and their experiences. Thus, this research aims to refigure how students who receive Realistic Mathematics Education (RME) literacy and numeracy skills improve based on teacher's experiences. The research subjects are third, fourth, and fifth-grade students in elementary schools in Padang. Three schools were selected for each grade level and taught by three teachers with different experiences. The students were given literacy and numeracy problems before and after RME instruction. The answers were assessed and grouped to examine the student's literacy and numeracy achievement. The research results show that student's literacy and numeracy skills are better with RME learning. Student's literacy and numeracy skills are not influenced by teachers' experience.

This study aims to design case-based learning with lesson study learning trajectory with the help of teaching aids to make students understand Prim’s, Cruscal’s, and Djiksra’s Algorithms. The validation study was selected because it is a suitable method for this research. The research subjects were 41 Mathematics Education Study Program Students at Universitas Negeri Padang. This research data were collected using Interview guidelines, journals, and observation sheets. Data analysis was carried out by transcribing interviews, reducing, presenting, and drawing conclusions from the data. A lesson study was chosen as an alternative to improve and reflect on the learning process. Moreover, two expert lecturers supervised the groups during the learning process. A proper design of case-based learning with lesson study learning trajectory with the help of teaching aids development process is obtained. Using a case-based learning method can make students understand Prim’s, Cruscal’s, and Djiksra’s Algorithms. This design can be used by the other lecturers to provide a learning process of Prim’s, Cruscal’s, and Djiksra’s Algorithms or other topics.

First-order Ordinary Differential Equation (ODE) has many applications in physics, engineering, biology, economics, and ecology. Therefore, mastering the concepts and methods of solving ODE is essential for students to be able to apply mathematics in solving real-world problems. However, the teaching of first-order ODE has not paid attention to practical applications, so that students have difficulty linking theory with real cases. This study aims to analyze the implementation of the SOLO taxonomy and Newman Error Analysis (NEA) in first-order ODE. The methodology used is a case study. The research subjects consisted of nine students of the mathematics department of FMIPA Universitas Negeri Padang. Data were collected through tests, interviews, and documentation. Then the data were analysed quantitatively and qualitatively. The results showed that there were five errors in solving first-order ODE made by students, namely Reading Errors (RE), Comprehension Errors (CE), Transformation Errors (TE), Process Skill Errors (PE), and Encoding Errors (EE). Some of the causes of these errors include students' low ability to read mathematical symbols, students' inaccuracy, not being able to use algorithms correctly, not mastering the concepts of algebra, differential, and integral, as well as not understanding in determining the systematic solution of the problem and not being accustomed to writing the final answer. This information can be used as a guideline for lecturers in designing strategies and lecture designs for first-order ODE.
