This study aims to determine the profile of students' oral argumentation skills based on Socioscientific Issues in the Microbiology course. This type of research is a descriptive study in order to obtain an overview of the quality of oral arguments of sixth semester students. The sampling technique used was purposive sampling, totaling 37 students of science class 2017. The instruments used were audio recordings and anecdotal notes. The assessment of the quality of students' oral arguments is based on the Toulmin's Argumentation Pattern (TAP) pattern which consists of claim, data, warrant, backing, and rebuttal elements. The results showed that science students had the quality of oral argumentation which was still at level 1 where student arguments only consist of simple claims with opposing claims obtaining a percentage of 12%,, level 2 had a percentage rate of 88% while level 3%, level 4% and level 5% of 0% means scientific argumentation ability science students are still relatively low. This finding will be the basis for researchers to evaluate the learning program that has been applied in the Microbiology course and become the basis for further research related to learning strategies in improving the oral argumentation skills of prospective science teachers.

The development of technology-based teaching materials is one of the competencies that teachers must have in dealing with technological developments in the digital era, coupled with the current pandemic conditions, teachers are forced to develop online-based learning including learning for early childhood. As a professional Early Childhood Education teacher, of course, you must have competence in developing technology-based teaching materials, but in the implementation of Early Childhood Education, there are still many educators who do not have this ability because there are still many PAUD teachers who have not received Early Childhood Education. For example, in Curug subdistrict, which is located not far from the government center, which has 55 Early Childhood Schools, and only two Kindergarten schools have State status, the rest are “SPS” study groups that are voluntarily managed by the community. Departing from these problems, the community service planning program which aims to assist in the development of technology-based teaching materials for early childhood to early childhood teachers in Curug District, Serang City, Banten. This community service activity is carried out with online workshops and mentoring for PAUD teachers to be able to make technology-based teaching materials in a simple form through learning videos tailored to the needs of a pandemic like today The mentoring activity was carried out for one month, and the results obtained from this activity were that early childhood teachers were able to make teaching materials in the form of learning videos that could be used to help the learning process from home during this pandemic.
