Researchers did not force teachers to use teaching methods, hence the experiment just measure correlation and not causation. So, there is a correlation between teaching methods and teaching outcomes. What is causing what is a matter of guessing. A possible causation scheme is that mathematical ability causes teaching methods and teaching outcomes, read the article: "the higher the number of struggling students, who scored in the bottom 15 percent in kindergarten, in a first-grade teacherâ€™s classroom, the more likely the teachers were to use manipulatives (hands-on materials), calculators, music and movement", hence mathematical ability influences teaching methods. In symbols, A correlates with B because C causes A and C causes B. No causation between A and B in either direction is necessary.beroalhttps://www.blogger.com/profile/13229768366613602827noreply@blogger.com
