Abstract: In our experiment we made a research on the role and peculiarity of recognition of patterns in solving applied algebrical problems of equation by the students of junior high schools.In solving these problems, the recognition of patterns appear mainly to be the differenciation of types of problems.The result shows that the subject's recognition of type of the problem determines whether he can solve it quickly and correctly or not.To recognize definitely the type of an applied problem, the student must abstract definite general relationships or structures from the concrete semantic context of the problem. This ability can be improved through drills with a variety of exercises.
