Development of Scientific Critical Thinking (SCT) model learning devices based on Sasirangan local wisdom to improve creative thinking skills Available to Purchase

Research development of Scientific Critical Thinking (SCT) model learning devices based on Sasirangan local wisdom to improve creative thinking skills of electrolyte and non-electrolyte solution topics aims to produce valid, practical, and effective learning devices. The development model used is a 4D model that has to define, design, develop and disseminate stages. However, the dissemination stage was not implemented. Limited trials of developed learning devices were conducted on Chemistry School 2 students. The data collection techniques were through validation sheets, implementation sheets, and tests. The data were analysed using descriptive analysis. The results showed that the developed learning device had met the following criteria: (1) the SCT model device was valid because the lesson plan, worksheet, teaching materials, and test instruction components were in the valid category; (2) SCT model devices are practical because the phases of the SCT model can be carried out properly, and (3) SCT model devices are effective because of N-Gain creative thinking skills of 0.66 with moderate criteria. The results showed that Scientific Critical Thinking (SCT) model learning devices based on Sasirangan local wisdom topic electrolyte and non-electrolyte solutions are feasible and used in chemical learning.
