<![CDATA[This study aims to determine the effect of the experimental method on the development of the concept of cause-and-effect thinking in early childhood Group B at TK Negeri Pembina Lambu, Bima City.

The results showed that the average score of children’s cause-and-effect thinking ability increased from 34.45 at the pretest to 47.09 at the posttest, with an increase of 12.64 points. The results of the Wilcoxon test obtained Asymp. Sig. (2-tailed) of 0.003 which is smaller than 0.05, so H0 is rejected and H1 is accepted. Thus, it can be concluded that the experimental method has a significant effect on the development of the concept of cause-and-effect thinking in early childhood Group B at TK Negeri Pembina Lambu, Bima City.]]>
