Abstract
We evaluate a randomized controlled trial (RCT) in the United Arab Emirates of an innovative early-grade literacy curriculum based on insights from cognitive science studies on language acquisition. A key problem faced by Arabic speakers learning to read, particularly those from poorer households, is the difference between the (origin-specific) Arabic dialects used at home and the Modern Standard Arabic (MSA) used for instruction. This Arabic diglossia (use of two language varieties) leads students in the Arab world to view MSA as a foreign language (Eviatar and Ibrahim, 2014) and reduces interest in learning. We test a newly developed reading and oral grammar MSA curriculum called Iqra (derived from the Arabic word for “read”) for students entering primary school. Iqra relies on perceptual and statistical learning of language to help students detect visual patterns and probabilistic structure in MSA that they would not learn at home. Practice and systematic repetition of analogic, predictable patterns help transfer information into implicit memory, which is durable and facilitates automaticity (Abadzi and Martelli, 2014; Abadzi, 2018). The curriculum has shown promise in a pilot study in the United Arab Emirates. This study will test the program in a full-scale RCT, including impact on literacy and measurement of the underlying cognitive processes hypothesized in the theory of change.

Experimental Details

Interventions

Intervention(s)
Iqra is an early grade Arabic literacy curriculum. The curriculum applies insights from cognitive science to instruction of Arabic for beginning readers. Practice and systematic repetition of analogic, predictable patterns help transfer information into implicit memory, which is durable and facilitates automaticity (Abadzi and Martelli, 2014; Abadzi, 2018).

Experimental Design

Experimental Design
Cluster RCT. The unit of randomization is the classroom. Primary school classrooms are randomly assigned to Iqra or control. Control classrooms receive only the business as usual approach to Arabic literacy. We stratify random assignment by school. Half of a school's classrooms designated for the study are randomly assigned to Iqra, half to control. Classrooms consist of first grade or kindergarten students, depending on the school. Control classrooms receive the standard version of Arabic literacy.

Experiment Characteristics

Sample size: planned number of clusters
83 classrooms (spread across 26 schools)
Sample size: planned number of observations
target: 83 classrooms * 15 students = 1,245 students. In practice, the number of students will be smaller, because not all classrooms have 15 students.
Sample size (or number of clusters) by treatment arms
42 classrooms treatment, 41 classrooms control
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
MDE for primary outcome (literacy) in sd units = 0.25. Assumptions: 5% test size, 80% power, 83 classrooms (42T/41C), 15 students/classroom, ICC = 0.2, control sd = 0.8 (to account for precision gains from baseline)
