Technology-Based Tools for English Literacy Intervention: Examining Intervention Grain Size and Individual...

Area of Science:

• Educational Technology
• Developmental Psychology
• Applied Linguistics

Background:

• Technology is crucial for educational interventions, especially for struggling learners.
• Early literacy interventions in bilingual settings require tailored approaches.
• Tablet-based applications offer a novel medium for literacy skill development.

Purpose of the Study:

• To evaluate the efficacy of tablet-based literacy interventions for primary grade students.
• To compare the effectiveness of phoneme-level, rime-level, and word-level interventions.
• To investigate the moderating roles of individual differences and bilingualism on intervention outcomes.

Main Methods:

• 147 primary grade students in Singaporean learning support programs participated.
• Students were randomly assigned to phoneme-, rime-, or word-level interventions delivered via iPads over 14 weeks.
• Assessments included word reading, pseudoword decoding, spelling, phonological awareness, orthographic awareness, cognitive ability, statistical learning, and bilingual vocabulary.

Main Results:

• All intervention groups showed improvements in literacy measures.
• The phoneme-level intervention demonstrated an advantage in decoding compared to the rime-level intervention.
• Individual differences, such as phonological awareness and statistical learning, moderated intervention effectiveness, with bilingualism also showing differential effects.

Conclusions:

• Tablet-based interventions can effectively supplement early English literacy programs.
• Intervention design should consider individual learning profiles, including phonological awareness, statistical learning, and bilingualism.
• Further research is needed to understand the interplay between technology-based interventions and diverse learner characteristics.
