Covid-19 has brought comprehensive changes in the field of education such as conducting learning with a distance learning system. The main purpose of this research is to analyze the teacher's view of learning needs and explore the factors that become obstacles in online thematic learning in elementary schools. This type of research is a mixed methods research, namely qualitative and quantitative research designs. The subject of this research is to take a sample of teachers in 20 elementary schools with a population of 200 teachers with a sample of 20 teachers. The sampling method used simple random sampling. Quantitative data in the form of samples based on questionnaire scores from 5th grade teachers with a sample of 20 teachers from 20 elementary schools. Data analysis is used to draw final conclusions on the results of the data, both from interviews, observations, and documents using interactive analysis techniques, namely data collection, data condensation, data display (data display) and drawing conclusions. The results showed that the thematic learning system had not been maximally implemented in schools; it is necessary to get used to implementing an android-based system which includes zoom for face-to-face online meetings, learning materials and evaluation of learning, so that teachers can explore the learning system used during the Covid-19 pandemic. In conclusion, the learning system in thematic learning during the Covid-19 pandemic still needs to be developed and explored because there are obstacles in the implementation of the learning process.

The use of Augmented Reality can increase the activities of students to blend into a natural learning environment no longer abstract. It was merging virtual objects and fundamental interactions anytime and anywhere, which can present 3D objects, which are the most important features of Augmented Reality, resulting in a learning experience different from before. The main purpose of this study is to focus on teachers' views related to material needs and the supporting factors in the acceptance of Augmented Reality, especially in science learning in elementary schools. This study took a sample of teachers in 20 public elementary schools in Surakarta, Central Java, Indonesia, with a total population of 200 teachers with a sample of 30 teachers. The sample includes teachers who have years of teaching experience with different schools. The result is that STEM and Augmented Reality have not been maximally applied in schools; There needs to be broader socialization and training to the need for various Augmented Reality-based science materials that need to be developed.
