A Video-Annotated Learning Review System with Vocabulary Learning Mechanism to Facilitate English Listening Comprehension

With the rapid development of information technology, computer assisted language learning (CALL) has become a developing trend. This study proposes a novel video- annotated learning and review system with vocabulary learning mechanism (VALRS-VLM), which can assist learners to manually mark any video section that they cannot fully understand, and then clarify the pronunciation and usage of the unfamiliar vocabulary words appearing in the video section through an online dictionary, so as to enhance learners’ English listening performance and perception. To verify the effectiveness of the proposed VALRS-VLM, this study examines the effects of the learners in the experimental group using the VALRS-VLM with those in the control group using the video-annotated learning and review system without vocabulary learning mechanism (VALRS-NVLM) on English listening comprehension performance, learning satisfaction, technology acceptance, cognitive load, and learning retention. Analytical results show that the learners in the experimental group achieved remarkably better-listening comprehension performance and learning retention than those in the control group. Besides, both groups of the learners showed good learning satisfaction and technology acceptance, and low cognitive load. This study confirms that the proposed VALRS-VLM could effectively assist learners in facilitating English listening comprehension performance as well as achieve good learner perceived usefulness and easy of use.
