• Resumen

  • The objective of this case study was to investigate the ability of 10th graders and pre-service teachers to solve logical�mathematical thinking challenges. The challenges do not require mathematical knowledge beyond that of primary school but rather an informed use of the problem representation. The percentage of correct answers given by the 10th graders was higher than that of the pre-service teachers. Unlike the 10th graders, some of whom used various strategies for representing the problem, most of the pre-service teachers� answers were based on a technical algorithm, without using control processes. The obvious conclusion drawn from the findings supports and recommends expanding and enhancing the development of logical�mathematical thinking, both in specific lessons and as an integral part of other lessons in pre-service frameworks.
