The effects of hands-on content-language integrated learning on fourth graders’ acquisition of target vocabulary and procedural knowledge in Taiwan

Despite the widespread use of multimodal pedagogies in Content and Language Integrated Learning (CLIL) contexts, empirical studies specifically focusing on the impact of hands-on learning on target vocabulary and procedural knowledge acquisition in CLIL Social Studies, particularly in Taiwan, are relatively uncommon. Grounded in embodied learning theories, this study investigated the comparative impact of hands-on learning versus worksheet-based instruction on fourth graders’ target vocabulary acquisition and procedural knowledge within a CLIL Social Studies setting in Taiwan. The study also explored students’ perceptions of their learning experiences with these instructional methods. This quasi-experimental study involved four intact fourth-grade CLIL Social Studies classes from three elementary schools in Taiwan, comprising 40 students in the Experimental Group (EG), who engaged in hands-on learning, and 34 students in the Control Group (CG), who engaged in worksheet-based learning. Activities included Chinese dumpling making, bird’s nest building, and designing a pot of succulents. Data were collected through pre- and post-tests to assess target vocabulary acquisition and procedural knowledge, followed by learner experience surveys to evaluate students’ perceptions of their learning experiences. The analysis included paired-samples t-tests, independent-samples t-tests, and thematic analysis of open-ended survey responses. Results revealed that the EG significantly outperformed the CG in both target vocabulary acquisition and procedural knowledge across all three activities, with large effect sizes (d = 1.05–1.51 for target vocabulary and 0.95–2.89 for procedural knowledge), demonstrating the effectiveness of hands-on learning. However, while significant differences were observed in memory retention of target vocabulary and procedural knowledge from the survey results, no significant differences were found between the EG and CG in terms of perceived ease of learning. These findings suggest that hands-on learning offers substantial benefits over traditional worksheet-based instruction in CLIL settings, though the transition to hands-on methods may require additional support. Practical implications include the strategic selection of relevant vocabulary, the implementation of structured hands-on approaches, and the emphasis on behavioral reinforcement to enhance learning outcomes.
