en پژوهشی اصيل Original Research <strong>Aims:</strong> The present study aimed to investigate the effects of Problem based Learning strategies on communication skills in pediatric nursing learning among undergraduate nursing students.<span dir="RTL"></span><br> <strong>Materials & Methods:</strong> This quasi-experimental study with a nonequivalent control group posttest-only design was conducted on undergraduate nursing students in Kohgiluyeh-Boyer Ahmad province. The sampling method was multistage cluster sampling. The total sample size was 95 in different classes of Traditional Problem Based Learning (TPBL=30), Hybrid Problem Based Learning (HPBL=30), and Conventional Teaching and Learning (COTL=35). The experiment was conducted over eight weeks, during which the participants met one two-hour session and two two-hour sessions each week. The three groups were compared for their communication skills at the end of the instruction. Data were collected using the Bayer-Fetzer Kalamazoo communication skill checklist and analyzed by one-way ANOVA and Tukey&#39;s post hock test.<br> <strong>Findings:</strong> There was a statistically significant difference in the mean scores of communication skills for the three groups evaluated by the simulated patient (p=0.001) and the researcher (p=0.001). TPBL and HPBL instructional strategies enhanced students&rsquo; communication skills more than COTL.<br> <strong>Conclusion:</strong> TPBL and HPBL instructional strategies are more effective than COTL, and PBL can be useful where there are shortages of instructors or faculty members to teach PBL groups in a large classroom setting.<br> &nbsp; Problem-Based Learning,Communication,Pediatric Nursing,Learning, 21 27 http://jccs.yums.ac.ir/browse.php?a_code=A-10-45-1&slc_lang=en&sid=1 M.
