This study aims to investigate the effects of AI chatbot-based activities on elementary English learners’ vocabulary abilities and affective domains. The participants were 109 5th grade students who were divided into two group: the experimental group which used the chatbots and the control groups which took the same classes but didn’t use the chatbots. The research tools were vocabulary test in the vocabulary abilities and survey in the affective domains. Each group was pre and post tested and statistical analysis were conducted through an independent samples t-test and a paired samples t-test. The results of this study were as follows: First, the use of chatbots in the experimental group had a positive effect on learners’ vocabulary abilities compared to the control group. Further, there was an increase between the pre-test and post-test scores in the aspects of literacy and sentence composition. Second, the same results were evident in the affective domains as in the vocabulary abilities, especially learners’ interest and confidence. Additionally, it was found that accuracy of chatbot’s speech recognition was comparatively low; this is a feature which needs to be improved. It is suggested that follow-up studies are needed to conduct the experimental classes by expanding the number of participants or the period of study to gather more empirical evidence.
