Some students feel that mathematics is unnecessary, resulting in their interest in learning being low and learning outcomes also being low. To overcome this, one approach that can be taken is experiential learning. This approach is based on four phases, namely real experience, reflective observation, abstract conceptual, and active experimentation. The four phases involve students in the learning process through acting, reflecting, thinking and applying. The aim of this research is to describe the learning process carried out using an experiential learning approach to trigonometry material to improve student learning outcomes. The research was conducted on 35 class X students. The data collection methods used were tests and field notes. The research results show an increase in student learning outcomes in three aspects, namely student learning completeness which reaches a score of more than or equal to 75, students' activeness in asking questions, arguing and working together in groups, and students' enthusiasm in taking tests given by the teacher. In conclusion, the application of experiential learning in class X trigonometry material can improve student learning outcomes.

The use of artificial intelligence technology in education continues to evolve, one of which is through the application of ChatGPT. This study aims to analyze the results of solving numerical integration problems with the help of ChatGPT compared to manual methods. Numerical integration is an important method in mathematics and various disciplines for calculating the integral values of complex functions. However, manual methods require a deep understanding and high mathematical skills, with a considerable amount of time and repetitive processes that often result in inaccurate solutions. This research attempts to explore the potential of ChatGPT as an educational tool, which has not been extensively discussed in previous literature, especially in solving complex mathematical problems. In this study, a number of numerical integration problems were solved using manual methods, such as the Trapezoidl and Simpson's methods, as well as with the help of ChatGPT. The results were then compared in terms of solution accuracy. The research findings indicate that ChatGPT is capable of providing accurate solutions, with results comparable to manual methods in many cases. The analysis shows that ChatGPT can be used as an aid in solving numerical integration problems because it can provide accurate results comparable to manual methods. However, manual methods are still necessary to maintain a balance between understanding basic concepts and utilizing technology in learning.

This study aims to improve students' understanding skills in learning Mathematics, especially in Trigonometry material by using tic tac toe game-based learning media, which is called the Tic Tac Toe game. The Tic Tac Toe game is a type of tic tac toe game in which players mark the spaces in an 8×8 grid with their chips. The player who manages to place 5 tokens using the chips in a row in a horizontal, vertical or diagonal row will win the game. The Tic Tac Toe game is a fun and challenging game for students who play it. Students as players are required to answer the math questions listed on the question cards to be able to place chips into the chip spaces or boxes on the game board. The research conducted was in the form of R&D (Research and Development) development research. This research aims to develop a new product or perfect an existing product (Sugiyono, 2015). This research is an educational research and development study which aims to develop learning resources for educational games by utilizing the Tic Tac Toe game with trigonometry for class XI. The development model used by researchers is the ADDIE (Analysis-Design-DevelopmentImplementation-Evaluation) model which will be carried out in the ADDIE stages. ”. This game media consists of game boards, player chips, game cards and guidebooks. The game Tic Tac Toe is a development of the game Tic Tac Toe in general. Tic Tac Toe games usually only have a 3x3 grid, in contrast to Tic Tac Toe which presents a view with an 8x8 grid so that the scope of players can be even wider. In addition, this game media is also made with a size of 60x68 cm, accompanied by a magnetic plate on the board so that players can attach chips equipped with magnets to the game board. Another difference can be seen from the number of players who can play the game, where in the usual Tic Tac Toe game it can only be played by 2 people, while the Tic Tac Toe game can be played by more than 2 people or in groups.
