Learning new words from an interactive electronic storybook intervention

Area of Science:

• Educational Technology
• Applied Linguistics
• Developmental Psychology

Background:

• Children with limited early vocabulary knowledge face significant risks for reading failure.
• Early vocabulary development is crucial for academic success.
• This study addresses vocabulary acquisition challenges in Grade 1 isiXhosa-speaking children.

Purpose of the Study:

• To evaluate the efficacy of a mobile application-based interactive e-book for vocabulary learning.
• To measure the acquisition and retention of new words at various lexical levels.
• To assess the suitability of the intervention for the South African context.

Main Methods:

• A randomized controlled trial with pre-test/post-test design was employed.
• An experimental group received the e-book intervention, while a control group received a delayed intervention.
• Mixed-model repeated-measure Analysis of Variance (ANOVAs) analyzed differences, with follow-up testing for retention.

Main Results:

• The e-book intervention facilitated rapid vocabulary acquisition ('fast-mapping').
• Participants developed robust lexical representations of newly learned words.
• Vocabulary knowledge was retained eight weeks post-intervention.

Conclusions:

• Multimedia technology, like interactive e-books, can deliver effective vocabulary training to at-risk young children.
• This approach is particularly valuable in resource-limited environments with inadequate parental support for vocabulary development.
• The study highlights a viable strategy to mitigate academic failure linked to poor vocabulary skills.
