The educational environment is significantly and positively related, shown because the significance value is 0.02 < 0.05, then it is correlated and the Pearson correlation value is 0.319 > 0.213 r table so that based on the correlation value greater than r table, there is a relationship between the educational environment variable and students' interest in learning science
