Evaluation of Vocabulary Learning Apps Based on Vocabulary Knowledge Framework

This study selected three representative English vocabulary learning apps in China and adopted Richards’ framework of vocabulary knowledge, incorporating the dimension of phonological knowledge, to analyze and evaluate these apps across eight dimensions of vocabulary knowledge. The research found: (1) partial neglect of phonological knowledge of vocabulary, (2) insufficient coverage of morphological knowledge, specifically neglecting roots and affixes, and (3) inadequate consideration of semantic value of vocabulary, which impacts learners’ accurate comprehension and use of vocabulary to express emotions, attitudes, and evaluations. Additionally, the analysis highlights strengths and weaknesses of the apps: BaiCiZhan covers vocabulary knowledge extensively but lacks English definitions and nuanced semantic distinctions; BuBeiDanCi covers all aspects of vocabulary but may overwhelm learners with cognitive load; MaiMemo aids quick vocabulary acquisition but may limit deep understanding. According to user feedback, there is a stronger preference for enhanced personalized features. Evaluating vocabulary learning apps assists language learners in selecting and effectively using applications that suit their individual needs and provides insights for the development and refinement of such software.
