Mathematics teaching system applying Habuta learning and 3-track progress program {MATHEMATICS EDUCATION SYSTEM}

The present invention relates to a math guidance system, and more particularly, to a math guidance system that applies a Habuta learning method that maximizes thinking skills through questions and discussions and a three-track progress program implemented to repeatedly learn the progress of several grades. it's about

In mathematics, grades rise only when the balance between lecture learning, which is seen with the eyes and heard with the ears, and practice learning by hand is right. Therefore, in the revised education that emphasizes mathematics education faithful to the principles, it is necessary to properly understand the concept and development process of mathematics and practice expressing them. However, 50% of middle school students and 70% of high school students give up on mathematics midway through reading their interest due to the influence of Korea's unique entrance exam-oriented education method, emerging as a serious social problem. In addition, students who lag behind in learning because learning by level is not progressing easily give up mathematics.

As a conventional technique for solving the above problems, Korean Patent Registration No. 10-1180235 (August 30, 2012) discloses a user-customized on-offline computational power mathematics education method on the homepage of an on/offline mathematics learning system. After the user accesses the user, a first step of performing user subscription; and a second step of the on/offline math learning system performing a math ability level test for the user who has signed up; and the on/offline math A third step in which the learning system performs a level arrangement and graded learning process in which learning starts according to the level of the tested user; And the online/offline math learning system performs grade adjustment of the user by comparing the user's solving time with respect to a predetermined time limit in order to perform repetitive learning through scoring for the performed learning, and average score and correct answer rate. A fourth step of performing grade adjustment to determine promotion, lower grade, or grade maintenance according to a predetermined standard table by calculating Courses A to C are "addition problem courses", courses D to F are "subtraction problems courses", courses G and H are "multiplication problems courses", and courses I and J are "division problems" Each of the A to J courses is further divided into Level 1, Level-2, Level-3, and Level-N, and the level of difficulty increases from ascending to descending order, and the fourth step is If (user solving time/(preset time limit * 60%)) is greater than 1, it is lower grade, and if it is less than 1, the score calculated as "Y (score) = (average score + correct answer rate)" is substituted into a predetermined standard table and compared. If the average score of the corresponding learning process is higher than the predetermined average score and the percentage of correct answers, a promotion is taken, and if the average score or the percentage of correct answers is less than the predetermined average score, the level is maintained, but the user's solution time in the fourth step is within 60% of the preset time limit. Learning is performed and learning takes place within 60% of the time limit throughout the one-week learning period, and according to the process-specific adjustment table, if the correct answer rate and average score level of the course the user has learned is higher than the level, the level is adjusted upward by one level. A user-customized on-offline computational power mathematics education method characterized in that the progress is known.

However, the above-described user-customized on-offline computational power math education method is a memorization and injection method that repeatedly memorizes a given pattern for each unit, in which a level test is conducted on the user and a customized problem is presented. Therefore, it is a method of studying mathematics that only teaches how to solve problems, which hinders systematic concept learning. Even if the grade is raised by repetitive memorization and injection methods, in the next grade, there is a disadvantage in that students do not know how to understand the problem and apply the concept to the problem, so their grades eventually drop, and they lose interest in mathematics after falling to the grade.

As another conventional technology, in Korean Patent Registration No. 10-1334992 (November 25, 2013), in a textbook for learning mathematics, it is organized by unit according to the table of contents of mathematics subjects, and the basic concept for solving mathematical problems is A concept summary section organized and classified by MAC number; and a basic problem section that is described so that one concept organized by the minimum unit MAC number of the concept summary section classified by MAC number can be applied and solved. ; and an exercise problem section written so that one or more concepts organized by the minimum unit vein number of the concept arrangement section classified by the MAC number can be applied and solved; and a commentary and answer section in which the commentary on the practice problems described in the exercise section is arranged and described by the minimum unit Mac number or the minimum unit unique Mac number, and the Mac number written in the concept summary section is A textbook for learning mathematics in which corresponding subheadings are described together and a pulse box is further provided at the top of the concept summary unit is known.

However, the above textbooks for learning mathematics encourage students to go back to the basic concept when they get stuck while solving a math problem, check the concept, and solve the problem again, and solve the problem without fully understanding the basic concept. It is a math study method that only teaches how to solve problems. It has the disadvantage of not being able to solve problems because it does not apply basic concepts to problems during the test.
