Audiovisual materials for oral expression development

Abstract

This research mainly aims to analyze the effects of the use of audiovisual materials in the development of oral expression. To test the effectiveness of the use of these materials in oral expression, two main tests were applied based on the Speaking part of the Cambridge Preliminary English Test (PET). The pre-test and the post-test were applied to the population of this study that consisted of 55 ninth graders of basic education of the Unidad Educativa "Vicente Anda Aguirre" during the first term of the first semester in the 2018- 2019 academic year. The students and their teachers were surveyed to obtain information regarding the practice in the classroom. A handbook was designed with ten lesson plans which were used within the intervention period. The lessons are based on the use of audiovisual materials such as computer and internet, online tools, flip charts, television and cartoons in combination with oral expression strategies such as planning, execution, and evaluation. After finishing the treatment to the experimental group, the post-test was applied, with which the results were obtained that were later analyzed and contrasted with those obtained in the pre-test. For the data analysis, the T Student mathematical test was used; and, to verify the reliability of the results, the Cronbach Alpha test was applied. The results obtained with the experimental group prove the effectiveness of the use of audiovisual materials in the oral expression of ninth graders. They showed a lot of interest and motivation with audiovisual materials to improve their oral expression. The students also improved their oral skills. It is concluded that the use of audiovisual materials has positive effects on oral expression and it is recommended that teachers include in their class planning audiovisual materials use to improve the performance of their students.
