This article shows the most relevant of the research, whose objective was to determine the influence of the DAR strategy: deconstruction, abstraction and reconstruction with a neuroscientific approach for the improvement of critical thinking. The theoretical foundation lies in cognitive neuroscience, brain plasticity, cognition and long-term memory. A quasi-experimental design was chosen for a sample of 48 students of Initial Teacher Training -FID of Primary Education. For data collection, an observation sheet was constructed and applied, which served to quantify the dependent variable: critical thinking. This instrument was validated by expert judgment and, for its reliability, Cronbach's alpha coefficient was produced. The results show that a large percentage of students in the experimental and control groups were located in the level in process, before the application of the stimulus. However, after it was applied, a large percentage of the experimental group was located in the achieved and outstanding levels; while the results of the control group remained unchanged compared to the pretest. The hypothesis was also tested using the Mann-Whitney U test, obtaining a value of (p-value =0.000), indicating a significant difference in the arithmetic means between the GE and CG;therefore, the null hypothesis was rejected and the research hypothesis was recommended.
