TLI Science we develop complex picture of student learning in Science. It shows that children come to school with powerful and sophisticated ways of reasoning about the material world that enable them to function effectively in many areas. It also shows that their reasoning is limited in important ways, it is bases on limited range of experience and it lacks the predictive and explanatory power of scientific reasoning. Through TLI, we can improve the critical thinking of the students. We will awaken their curiosity to open their doors to discover the way of mastery in science in all level.
