The authors focused on 2 teaching techniques of clinical reasoning, the technique Summarize, Narrow, Analyze, Probe the preceptor, Plan, Self-selected topic (SNAPPS) and the Clinical Reasoning Technique (CRT), and compared their efficiency to improve the clinical reasoning competencies of third-year undergraduate medical students.<br> <b>Materials & Methods: </b>The authors performed a prospective randomized, controlled, non-blinded crossover trial including year-3 undergraduate medical students. Judgment criteria consisted of the scores attributed to a test assessing the cognitive competencies of the participants which was a structured summary performed by the students after each session. Besides, a satisfaction Likert-scale questionnaire was fulfilled by the students. Statistical analysis was performed using SPSS software (version 20.0).<b><span style="font-family:"Times New Roman",serif"></span></b><br> <b>Results: </b>Seventy-two students were included with a mean age of 21.03 (SD:2,30) years. The mean scores of the students allocated to the CRT arm reached 4.62 (SD:2.93)versus 4.99 (SD:2.93) for the SNAPPS arm. No significant statistical difference was observed between the mean scores according to the method used. The analysis of the satisfaction questionnaire revealed that 75% of the students preferred CRT because of the collaborative work performed.<br> <b>Conclusion: </b>This study highlights the need for varying techniques to improve the critical reasoning skills of medical students. Besides, it pointed out students&#39; preference for collaborative approaches illustrating socio-constructivist theories of learning.</span></span></span></div> Clinical decision making, Diagnosis, Randomized clinical trial, Clinical judgement. 57 64 http://edujournal.zums.ac.ir/browse.php?a_code=A-12-2043-1&slc_lang=en&sid=1 mona mlika mouna.mlika@fmt.utm.tn 5300319475328460024950 5300319475328460024950 Yes University of Tunis El Manar.
