The characteristics of highly motivated children who get high grades are due to the excellent influence of their parents. For example, a few days after learning about “Hokkaido” in geography class, potatoes from Hokkaido and other prefectures are served at the dinner table. The impact of learning not only in words and knowledge but also in the form of objects and events ensures that memories are retained. There is a third variable that affects children’s physical and academic abilities. This third variable is called a confounding factor. The confounding factor of enthusiastic parents, who affect both children’s physical and academic abilities, seems to bring out various results. They make the goals and daily results that the children themselves have set visible. After visualizing the goals, there are also ideal families that subtly present the progress of their efforts so that they can be seen.
When arithmetic problems are given at school, they are done based on the curriculum guidelines. The degree of achievement of arithmetic problems is grasped in the so-called flow of goals, content, methods, and evaluation. Generally, there are three stages of evaluation to check whether a lesson has been understood. The first is a diagnostic evaluation test to check the academic ability before the unit. The second stage is a formative evaluation to check the degree of acquisition of each child after learning activities such as lessons and homework. In this formative evaluation in lessons, children who are behind will be supported by repeated supplementary instruction. The last stage is a summative evaluation test to grasp the learning progress and academic ability of the children. If the flow of diagnosis, formative, and summary can be grasped at any time, the academic formation of children can be grasped one by one in relation to the learning goals.
If digital textbooks are made, it will be possible to systematically arrange the learning contents from the first year of elementary school to the third year of high school on one tablet. It will also be possible to take tests at home using a tablet device such as a cloud database. If this kind of digitalization of education progresses, it will be possible to automatically record the education and learning process using cloud services. If this can be realized, there will be no need for national academic achievement tests conducted by the Ministry of Education, Culture, Sports, Science and Technology. It is said that in the academic achievement tests taken after schools reopened in 2020, there was a significant drop in the scores of students at the bottom. If education were digitalized, it would be possible to quickly and specifically identify which children in which areas are experiencing a decline in their grades. Once this information is known, it would be possible to provide the necessary support immediately.
