Technology and Reading: The Effects of CALL Glossing

Area of Science:

• Second Language Acquisition
• Educational Technology
• Applied Linguistics

Background:

• Previous research on L1 glossing's impact on L2 reading comprehension yields inconsistent findings.
• The effectiveness of Computer-Assisted Language Learning (CALL) glossing requires updated meta-analytic investigation.
• Key variables influencing CALL glossing effectiveness need examination.

Purpose of the Study:

• To update the meta-analytic research on CALL glossing studies.
• To investigate variables influencing the effectiveness of CALL glossing for L2 reading.
• To provide evidence-based recommendations for CALL glossing implementation.

Main Methods:

• Meta-analysis of existing studies on CALL glossing and L2 reading comprehension.
• Quantitative synthesis of effect sizes across studies.
• Examination of moderating variables such as gloss type and testing methods.

Main Results:

• An overall effect size of .84 indicates that CALL glosses significantly enhance L2 reading comprehension.
• Both productive and receptive testing formats are valid measures of L2 reading comprehension.
• Excessive CALL glossing does not guarantee improved comprehension; textual glossing with visuals is most effective.

Conclusions:

• CALL glossing is a beneficial tool for improving L2 reading comprehension.
• The design of CALL glosses, particularly the use of visuals, is crucial for maximizing effectiveness.
• Future CALL research should focus on optimizing glossing strategies and assessment methods.
