Learning represents a fundamental aspect of the educational process. The efficacy of the learning process is a key determinant of the extent to which educational objectives are achieved. Similarly, the quality of mathematical learning is a significant predictor of success in mathematics. The objective of this thesis is to examine the potential of managerial strategies to enhance the quality of mathematics learning. This research employs a qualitative methodology, specifically a case study design. Data were collected through in-depth interviews. The data sources, or resource persons, were selected using the snowball technique. The data were validated through the triangulation technique. The results demonstrated that: (1) The management of improvements to the quality of mathematics learning is conducted in three stages: planning, implementation, and assessment. (2) Teachers employ various strategies to enhance mathematics learning outcomes, including the provision of structured assignments. (3) The effective management of learning outcomes is contingent upon three key supporting factors: parental involvement, access to learning resources, and the principal's leadership model. (4) Persistent challenges, such as the pervasive belief that mathematics is inherently challenging and student motivation, must also be addressed.

Student learning outcomes are a reference for educators to determine the success or failure of students in carrying out the learning process in class. This study aims to determine the factors that influence mathematics learning outcomes in the material of flat-sided geometric shapes at SMP Negeri 4 Gunungsitoli Idanoi. The subjects of this study were class VIII students with 26 students. The instruments used in the study were a test of 5 questions and interviews. The data analysis method used in this study is a quantitative descriptive method. Based on the data exposure, the researchers concluded that the average student learning achievement was 73.00. From the data on student learning outcomes test scores above, a standard deviation of 11.1 was obtained from 26 respondents. Students with moderate learning outcomes are 53.85%, with high learning outcomes are 26.92%, and students with very high learning outcomes are 3.85%, with a completeness percentage of 65.38%. Low learning outcomes can be seen from interviews with students that 69.23% of students need help understanding the material the teacher explains during the learning process. In addition, from the results of interviews with subject teachers, it was obtained that aspects that often affect student learning outcomes are internal aspects, including lack of student interest in learning, lack of ability to understand the material, lack of student memory, lack of student skills in arithmetic and aspects of External factors include the lack of attention and support from the family to return to the lessons given by the teacher at home.

The objective of this article is to offer a general overview of how face-to-face learning can be utilized in the context of the new normal era and to identify potential learning models that teachers can employ in addressing educational challenges within this era. In the process of developing this article, a literature review method was employed. The data collection process included a comprehensive review of various references from national and international journals that are pertinent to the subject matter under discussion. Upon conducting thorough research, the author will then select, analyze, and present results in a systematic manner. The learning model represents a significant element within the context of learning. As an individual occupying a pivotal role in the learning process, the teacher is responsible for applying an optimal learning model to ensure the successful attainment of learning objectives. A selection of models that can be utilized for learning within the new normal era includes: Three learning models are worthy of mention: Blended Learning, Flipped Classroom, and Hybrid Learning. In applying any of the aforementioned models to the learning process, it is important to consider the specific characteristics of each learner and the abilities of the instructor.
