Abstract

Mathematics is a symbolic language of its characteristics is to use deductive reasoning and inductive reasoning methods. In the teaching of mathematics each subject is a unit so that the mastery of one subject is a support to learn the next subject. Similarly, the ability of students in carrying out calculating operations in mathematics lessons in developing students' critical thinking skills. To perform calculating operations on the right learning requires the right learning model and teaching materials. Therefore, the right learning model in cultivating students' critical thinking skills is a project-based learning model. This research aims to find out the ability to think critically through project-based learning models on the material of the theorem theorem phytagoras of students in class VIII of State Junior High School 5 West Leihitu District. The type of research used in this study is qualitative descriptive. The process of taking subjects is based on the highest value of group work on LKS. From the results of the group's work, 3 students were taken from the total number of students, namely 30 people. The instruments used in this study were researchers, tests and interviews. The data analysis techniques used follow concepts developed by Miles and Huberman, namely data reduction, data presentation, and inference.

Abstract

The difficulty experienced by the head of PAUD al Ashriyyah Nurul Iman in disciplining teachers and motivating them to comply with the foundation's policies is a problem that must be immediately found a solution. This research uses a qualitative approach, data sources obtained through interviews through zoom applications, documentation, and observation. This article found that PAUD al Ashriyyah Principal Nurul Iman in improving teacher discipline used autocratic style to be the dominant style, not seen other styles played by principals in the leadership model. The principal in improving the work discipline of his teachers does not always run smoothly, the obstacles and obstacles faced include that there are still a few teachers who are late in entering the classroom so that they need very strict supervision and guidance in terms of monitoring during learning hours, besides that there are other teachers in making learning tools so that there needs to be action in giving their assignments,  So the principal needs to tell what, how the task in detail should be done. To improve discipline in PAUD al Ashriyyah Nurul Iman, the principal does not play only one leadership style, but uses a democratic leadership style where employees or teachers have high work motivation and high competence abilities, or participatory leadership styles if teachers have low work motivation but high competence abilities
