<![CDATA[This research was motivated by the low level students problem-solving abilities in chemistry, particularly in reaction rate material. This study aims to examine the effect of the Google Sites-based flipped classroom learning model on students problem-solving abilities in reaction rate material. This study used a quantitative approach with a one-group pretest-posttest desaign. The instruments used in this study were 10 essay questions and 20 studens response questionnaires. Data collection was conducted through pretests and posttests. Data analysis used a paired sample t-test, after previously conducting prerequisite tests, namely the Shapiro-Wilk normality test, and the N-Gain test. The results of the data analysis showed a significance value of (p <0.001) for the paired sample t-test, indicating a statistically significant difference between pretest and posttest scores. The N-gain value of 0.8662 was categorized as high, indicating an increase in students problem-solving abilities after treatment. Based on the data analysis, it can be concluded that the Google Sites-based flipped classroom learning model has a positive effect on students problem-solving abilities in reaction rate material.]]>
