PurposeKeywords search is intuitive, simple to use and convenient. It is also thede factoinput interface for textual and multimedia retrieval. However, individuals often perform poorly when faced with exploratory search tasks that are common during learning, resulting in poor quality searches. The purpose of this paper is to examine how adolescent learners search and select videos to support self-learning. The findings allow for the identification of design concepts of video retrieval interface and features that can facilitate better exploratory searches.Design/methodology/approachParticipants were assigned two customized video search tasks. The think-aloud protocol is used to allow participants to verbalize their actions, thoughts and feeling. This approach offered rich insights to the participants’ cognitive processes and considerations when performing the search tasks.FindingsThis study identified five themes for exploratory video search behavior: selection of internet resources, query formulation/reformulation, selection of the video(s) for preview, getting acquainted with the video content, and making a decision for the search task. The analysis of these themes led to a number of design concepts, ranging from supporting exploration of topics to better interaction with metadata.Practical implicationsThe findings can inform future development of dedicated video retrieval systems interfaces that seeks to facilitate effective exploratory searches by learners.Originality/valueThis study contributes by suggesting design concepts for video retrieval system developers to support exploratory video searches.
