Abstract-The. This paper aims to analyze the feasibility of that learning strategy to be applied in elementary school classroom using K-13. The analysis was conducted qualitatively by comparing the characteristics of webbed or integrated thematic curriculum, the forms of K-13 at the elementary school, with the characteristic of CSBLS. The characteristics of integrated thematic curriculum incorporate various disciplines to achieve cognitive, affective, and psychomotor competence. The suggested learning approach is the scientific approach, which involves four main skills namely observing, questioning, experimenting, associating, and networking/communicating. Various activities neither have to be trained sequentially nor performed all skills in a classroom meeting. CSBLS has the steps that are in line with a scientific approach. The steps are concise of giving attention, understanding, exploring, sharing, game, assessment, and individual tasks. Understanding the steps, training the skill of questioning, observing, associating, communicating data, sharing step trained a verbal communicating and individual tasks involve all skills which are undertaken independently by students. According to its characteristics, the CSBLS can be applied in K-13 by a little adaptation. It only requires the change of learning materials from subject areas to themes as a learning content. The implementation of the CSBLS can facilitate individual differences especially related to elementary students' cognitive style and their tendency to prefer group activities.
