# Teaching analytics at high schools in the direction of improving problem solving competence through equipping with some tactics of cognitive activities for students

1.1 Establishment and development of problem solving capacit for students are important targets of mathematics Problem solving has important meaning in teaching mathematics and has been applied in curricula in many countries worldwide. Researching the relationship between the contents of Mathematics at high schools in Vietnam and common capacities which should be established and developed for students, Tran Kiel determines that problem solving competence is one of six specific capacities which should be established and developed for students through Mathematics. Therefore, the improvement of problem solving competence has currently been one of significant duties in teaching mathematics at high school in Vietnam. 1.2 Analytical content is potential to improve the problem sovling competence The analytical content contains may contexts which arise out problems and is an aspect which could be exploited to improve the problem solving competence. 1.3 The tactics of cognitive activities plays the signigicant role against the students regarding apprehension of mathematical knowledge as well as solution of mathematical problems Polya affirmed that teaching tactics (referred to as tactics of cognitive activities) is to develop the problem solving competence for students. In practical mathematics teaching, featured and skilful methods of surveying and changing objects to find out reasonable and optimal measures shall help the students perceive the beauty of mathematics, establish aesthetic feelong and inspire the passion for and interest in mathematics. Such methods play the role as means or tools which help the students occupy the whole knowlege of mathematics and solve successfully mathematical problems. And such methods are considered as tactics of cognitive activities. Equipping with tactics of cognitive activities for the students in teaching analytics is very necessary and considered as one of ways which contribute to establish and develop the problem solving competence. We have selected the research topic: “Teaching analytics at high schools in the direction of improving problem solving competence through equipping with some tactics of cognitive activities for students” therefrom.
