Resumen: The aim of this paper is to analyze the effect of extroversion on students'' attitude toward the combined use of a wiki and the video recording of oral presentations to improve communication skills using a quantitative approach. The model includes stress because it is considered an important aspect in public speaking situations, especially so in a case like ours where the videos will be available to the class. The students’ enjoyment and the relative advantages of the learning activity are also included because they may have an influence on satisfaction and course recommendation. A survey was carried out among first-year undergraduate students. Using partial least squares methodology, the results suggest that extrovert individuals perceive less stress and more enjoyment when performing this activity, which results in them having a better attitude toward it. A total mediation effect of enjoyment between extroversion and attitude is found. Our findings also confirm that stress acts as a barrier to satisfaction, but it does not create a negative reaction toward the activity. Finally, the results show the mediation effect of attitude between the perceived relative advantages and satisfaction and between enjoyment and satisfaction.
