摘要:The objective of this research was to determine the differences between the levels of logical thinking and solving mathematical problems of students from first to eighth semester of the program psychology of a public University, through a kind of descriptivo-correlacional study, using instruments that measure the level of logical thinking (TOLT), and mathematical problem solving (PRP). Was found at a general level a 56.7% in particular thinking, a 37.4 per cent in transition, and 5.8% in formal; in mathematical problem solving, the 50.9% is located in a low level, 19.9% in the Middle, and 29.2% high. The results indicate the existence of differences between the levels of thinking and mathematical problem solving in students from first to eighth semester of the programme of psychology of a public University, with a t =-4.676 to bilateral significance of 0.00.
