Preliminary research for the development of a 3D and VR-based English-language pronunciation program: Using the Delphi method

The objective of this research is to gather opinions from experts via the Delphi method to inform the future development of a 3D and VR (virtual reality)-based English-language pronunciation program for university-level students in Korea. The participants, consisting of a panel of experts and professors in English-language and multimedia education, completed three Delphi surveys. In the first Delphi survey, after the participants were asked open-ended questions on the areas and contents of a 3D and VR-based English pronunciation program, categorization was done to subdivide the answers into development area, criteria, and categories. Based on their answers, a second Delphi survey was designed to determine the participants’ level of agreement with the appropriateness of the questions related to the four areas (i.e., need and academic evaluation of the program, educational contents, teaching method and evaluation, and results and application) based on the CIPP (context input, process, and product evaluation) model. In the third Delphi survey, participants were shown the results and were asked to confirm or modify their answers. According to an analysis of the Delphi survey results, the need for development of a 3D and VR-based English-language pronunciation program is asserted, and recommendations are made regarding the content and application of the program.
