Changes in government policies in the education sector are to prevent the spread of Covid-19. This study aims to explore the results of changes in the learning process of a full-day school. The method used is descriptive qualitative with a case study. Data collected by observation, interview, questionnaire filling, and documentation. Data analysis using interactive qualitative by Miles and Huberman. The results in this study describe the school preparation in implementing changes in government policy about the learning process in a full-day school program during the New Normal. The learning can be well implemented with some development of the school itself following the New Normal Era health protocol in achieving educational goals. The learning in school can be carried out if there are careful preparation and discipline in applying it so the learning can be safely for school residents. The implementation of several changes to health regulations and protocols encourages the emergence of social distancing behavior and minimizes the possibility of a crowd in the school community.

If a system is arranged and implemented clearly, correctly, systematically, and reported responsibly, it will simplify the users' task. Therefore, the quality assurance system of education in primary schools is very important in accordance with existing procedures to maintain and advance the quality of education of a school. There needs to be an efficient, effective, and appropriate way to assure the quality of education in a school, namely primary schools. This study aims to describe the results of the analysis of the education quality assurance system at Bendosari SD N 2 (State Primary School 2), Sawit, Boyolali. The approach used in this research was a descriptive qualitative approach with case study design. This data collection technique was in the form of the results of observation activities, interview activities, questionnaire filling activities, and documentation activities. Sources of data in this study came from school residents such as: school committees, principals, teachers, students, parents of students, communities, and researchers. Data validity techniques to find the validity and validity of the data used data triangulation. Data analysis techniques used in this study were interactive qualitative data analysis by Miles and Huberman (2014) consisting of data reduction (summarizing data), data presentation (displaying data), and drawing conclusions from research. The results obtained in this study were to describe and explain that the quality assurance of education conducted by SD N 2 Bendosari, Sawit, Boyolali can be maintained properly and to improve the education quality assurance system in order to achieve a goal.

<em>The purpose of this research is to improve concepts comprehension two dimentional figure character through the implementation of cooperative learning model type Make a Match. The source of the data comes from teachers, students, and researches. The data collection technique is by test, interview, observation, and documentation. The validity of the data used content validity and data triangulation. The data analysis used interactive data analysis by Miles and Huberman (2014) which consist of data reduction, data presentation, and conclusion. The results of this research is the average scores that students classical mastery cycle I and cycle II increased. The average scores is 87,5 in cycle II with students classical mastery 88,89% or 16 students of 18 students is completed. The conclusion of this research is through the implementation of cooperative learning model type Make a Match can improve concepts comprehension mathematics leaning about two dimentional figure character.</em>
