Analytical Thinking Skills Through 21st Century Mathematics Learning Assessment in Classroom using Lesson study and Open approach.
The purpose of this research is to analyze the assessment of 21st century math learning among classroom teachers using a classroom education and open methodology. And analyze the analytical thinking skills of students in a classroom using an open classroom study and method. Those for Students have classroom analytical thinking skills that use a classroom education and an open-by-1 approach. Students exhibit their thinking through careful consideration and are able to reason. Principle similar or differences can be identified. 1) Grouping. Students can be grouped in order, categorize or categorize their knowledge of things. 2) Error classification. When students have misunderstandings in class Together, students can help identify the reason for the data error. Be able to interpret or state basic knowledge of knowledge, identify specific or draw logically. Until a new knowledge can be formed. 3) Summary of principles Students can summarize concepts as a method used to solve problems. By reasoning both inductive and deductive reasoning and 4) applying them, students can apply their knowledge of decimals to new problem situations.
