Title: To assess the potential cognitive abilities required for mathematical learning
Inventor: SONG IN KANG
IPC: G06Q50/20
Filed: 2021-03-02
Abstract: The purpose of evaluation of young learners, such as elementary school students and middle school students, should be to develop latent abilities for better learning, rather than discriminating between merits and demerits through ranking. However, the conventional method for evaluating mathematical ability is a method of evaluating by score and determining the ranking and a method of evaluating latent mathematical ability in a simple way. The evaluation methods need to be improved. In particular, mathematics requires more cognitive ability than other subjects, has a great impact on the achievement of other subjects, and plays an important role in the formation of self-confidence and character, and career selection. Therefore, when the latent cognitive ability (concentration, vocabulary comprehension, calculation ability, mathematical background knowledge, logical thinking ability, spatial perception) is evaluated in detail as a method for evaluating mathematics, the overall life or growth process such as a learning method, a way of thinking, living habits, and the like can be estimated. Since insufficient abilities are likely to be generated from wrong lifestyles or habits, the younger the age, the easier it is to change the wrong lifestyles or habits, so the way to evaluate the latent cognitive ability is important. To this end, the latent mathematical cognitive ability of an examinee can be evaluated with data on the level of difficulty per question, a reference time for solving questions, the setting of cognitive ability required for solving problems, and the response time. An objective of the present invention is to perform an evaluation using a personal computer or a mobile and to show results in both absolute and relative evaluations using an application so that a learner can achieve personal endeavors.
