A new vocabulary revision technique using WhatsApp: Peer-chain

Area of Science:

• Second Language Acquisition
• Educational Technology
• Applied Linguistics

Background:

• Effective vocabulary acquisition is crucial for English as a Foreign Language (EFL) learners.
• Traditional vocabulary learning methods may lack engagement and long-term retention.
• The integration of digital tools offers new possibilities for language pedagogy.

Purpose of the Study:

• To evaluate the efficacy of a novel "peer-chain" vocabulary revision technique.
• To compare the "peer-chain" technique's impact on vocabulary learning and retention against traditional methods.
• To explore EFL university students' perceptions of the "peer-chain" technique.

Main Methods:

• A mixed-method study with a pre-test, post-test, retention test control group design.
• Quantitative analysis involved a 42-question vocabulary achievement test (VAT) administered over eight weeks.
• Qualitative data were gathered through interviews with experimental group participants.

Main Results:

• Analysis of Variance (ANOVA) revealed a significant difference in vocabulary achievement favoring the "peer-chain" group.
• Students using the "peer-chain" technique demonstrated superior vocabulary learning and retention.
• Qualitative analysis indicated positive learner perceptions of the "peer-chain" technique.

Conclusions:

• The "peer-chain" technique, especially when integrated with WhatsApp, is a promising approach for EFL vocabulary instruction.
• This method shows greater success in vocabulary learning and retention than traditional paper-based word cards.
• The findings support the adoption of technology-enhanced, collaborative learning strategies in language education.
