Can you correct naturally to me some questions? Please! 1. If a student has logical thinking (can comprehend concepts such as clause logic, predicate logic ...), they can use logical reasoning (deductive, inductive) Reality is different with the learning environment, it is almost based on the experience (example: probability, statistics). If a young person, a fresh student who only knows logical reasoning is compared with the people that have reasoning based on experience (over a long period of time), of course logical reasoning is not enough, they have to add the experience to be able to draw the lessons faster. So, how do we teach/prepare for students logical reasoning until they graduate so that they also have the ability to infer empirically. How to transition from personal experiences into common knowledge (to reduce the learning time)? 2. Which criterias/scales to believe that students must learn the way to get logical reasoning? Which criterias/scales to evaluate the reasoning skills? Which measures to evaluate the students that have good logical thinking? 3. How to develop reasoning skills for students who do not have the ability to reason?
