The biggest feature of K-thinking is quantification and vitality, which enables students with certain logical thinking to overcome learning obstacles quickly by using logical ability. Quantification means that learning objectives or tasks are specific and can be measured clearly. Students can know their learning progress and mastery at any time; The so-called vitality means that teaching is the essence of knowledge, so that students can master the origin of various disciplines and fundamentally control the learning context and overall routines. Students' "unconscious talent" is transformed into "conscious science". Time here is quantitative, achievements are quantitative, and progress is quantitative.
