Development of a Growth Mindset and Problem-Based Learning Model to Enhance Public Speaking Skills of Undergraduate Students

Abstract

This research aims to 1) synthesize and evaluate the growth mindset and problem-based learning model to enhance public speaking skills of undergraduate students, and 2) evaluate the effectiveness of the developed learning model. This study used the purposive sampling method, and the sample group consisted of 160 first-year undergraduate students who registered for the Speaking and Presentation for Careers. The research instruments were 1) a growth mindset and problem-based learning model, 2) a public speaking skills assessment form, and 3) a semi-structured interview form. The statistics used were mean, standard deviation, t-test (dependent), and content analysis.
The research results are as follows:
1. The teaching and learning model consisted of 6 steps (6E Model). Step 1: Explore and Define; Step 2: Establishing Empowering Goals; Step 3: Enhancement Planning; Step 4: Effort to Learn; Step 5: Empower for Growth; Step 6: Evaluate and Present). The efficiency of the model was found to be at the highest level of appropriateness by experts ( = 4.93, S.D. = 0.10).
2. With regard to the effectiveness of the model, it was found that 1) the experimental group had a higher public speaking ability than the control group after they had been taught with the improved teaching model, and the difference was statistically significance at .05. 2) The students in the experimental group had a higher public speaking ability after they had been taught with the improved teaching model, with statistical significance at .05.
