Abstract

The problem of thematic learning in class II of SD N Kapunda, Sleman Regency, namely the level of confidence to present their own assignments or work is still low. The purpose of this study was to increase the self-confidence and communication skills of class II students at SD N Kapunda for the 2022/2023 academic year. This type of research is Classroom Action Research (CAR), which consists of 4 stages including planning, implementation, observation, and reflection. The subjects studied were grade II students at SD N Kapunda with 3 male students and 6 female students so that the total number was 9 students. The research process was carried out in 2 cycles. Data collection through tests and observations. The results of the study showed that the self-confidence and communication skills of class II students at SD N Kapunda for the 2022/2023 academic year had increased through the implementation of the Problem Based Learning (PBL) model. This can be proven by looking at the percentage gain for each variable. The confidence variable in the pre-cycle conditions obtained a percentage of 33.33%. In cycle I, there was an increase to 59.55%. Then it increased again in cycle II to 81.47%. For the communication ability variable in pre-cycle conditions, a percentage of 48.14 was obtained. In cycle I, there was an increase to 66.66%, and in cycle II it increased to 81.47%. Because the percentage gain for these two variables has exceeded 70%, this research stops in cycle II.
