The purpose of this qualitative descriptive study was to explore how online undergraduate students describe their use of instructional videos and their perceptions of the ease of use, usefulness, and enjoyment of instructional videos in colleges in the southeastern United States. According to the Technology Acceptance Model (TAM), the use of technology depends on the potential user's perceptions about the ease of use, enjoyment, and usefulness of the technology. The two research questions were, "How do online undergraduate students describe their use of instructional videos?" and "How do online undergraduate students describe their perceptions of the ease of use, usefulness, and enjoyment of instructional videos?" Eleven individual interviews and three focus groups were conducted, which resulted in a sample of 20 research participants. Thematic data analysis resulted in seven themes: use, usefulness, enjoyment, ease of use, length of video, video characteristics, and student factors. When deciding whether to use instructional videos, students consider if they need to use the video to obtain the grade that they desire and if they want to spend their time watching the video. The use of instructional videos is influenced by usefulness, length of the video, enjoyment, and occasionally, ease of use. Video characteristics and student factors may also influence the use of instructional videos, and content analysis revealed that instructor characteristics impact enjoyment. Usefulness, the most important determinant for use, is increased when the videos contain the specific information that is needed for success in the class, and a variety of time-saving strategies are used to obtain the information needed. The findings from this study can be used to make instructional videos more likely to be used and therefore more helpful.
