The Effect of Role-Play Simulation Learning on Undergraduate Students' Understanding of Parliamentary Processes in an Introductory Political Science Course
Main Article Content
Abstract
This research article aimed to: (1) develop role-play simulation lesson plans on parliamentary processes for the SO2102 Introduction to Political Science course that meet established quality criteria; (2) compare undergraduate students' understanding of parliamentary processes before and after the intervention; (3) evaluate post-test understanding against a 70% criterion; and (4) investigate students' satisfaction with the role-play simulation instruction. A quasi-experimental classroom action research design employing a one-group pretest-posttest approach was adopted. The population consisted of all 16 first-year Bachelor of Political Science students enrolled in SO2102 at Mahamakut Buddhist University, Isan Campus, during the first semester of the 2025 academic year. Research instruments included five 3-hour role-play simulation lesson plans based on Shaftel and Shaftel’s nine-phase model, a 30-item multiple-choice test based on Anderson and Krathwohl’s seven cognitive dimensions of understanding, a participation rubric, a satisfaction questionnaire, and reflective journals. Data were analyzed using means (), standard deviations (), dependent samples t-tests, one-sample t-tests, effect size (Hedges' g), and content analysis.
The results revealed that:
1. The five lesson plans achieved an overall appropriateness score at the highest level (). The test items demonstrated content validity (ranging from .60 to 1.00), difficulty indices () from .35 to .75, discrimination indices () from .25 to .60, and Kuder-Richardson 20 () reliability of .82.
2. Mean post-test understanding scores () were significantly higher than pre-test scores (), t(15) = 15.42, p < .001, featuring a very large effect size (Hedges' g = 2.45).
3. Post-test scores significantly exceeded the 70% criterion (t(15) = 6.05, p < .001), with 14 students (87.50%) reaching the standard.
4. Overall satisfaction with the instructional approach was rated at the highest level (). Among the seven cognitive dimensions, inferring yielded the highest percentage gain (50.00%), whereas classifying yielded the lowest (26.00%). Qualitative analysis of reflective journals yielded three core themes: comprehension of legislative mechanics, appreciation of parliamentary standing orders as minority protection devices, and the emergence of political empathy.
