Prior work
This trial does not extend or rely on any prior RCTs.
We conducted a RCT of a gamification-intensive online platform among fourth graders in public primary schools in Santiago, Chile. We evaluated the effect of this program on math and language scores from the Chilean Standardized National Exam (SIMCE).

Primary Outcomes

Primary Outcomes (end points)
Standardized math and language scores from SIMCE (Chilean National Standardized Exam)
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
Standardized math and language scores from midline and endline exams. Non-academic outcomes using indices for: intrinsic motivation, self-concept, anxiety, growth mindset, preferences for teamwork, and preference over use of technology at school
Secondary Outcomes (explanation)
Test scores from midline and enline exams were applied in case access to SIMCE was not granted. Non-academic outcomes are indices constructed with questions from the endline survey and SIMCE survey.

Experimental Design

Experimental Design
We implemented a randomized controlled trial to estimate the causal effect of the ConectaIdeas program on learning. We recruited 24 public schools located in Santiago that had at least two fourth-grade sections. The schools had to have been classified in the two lowest socioeconomic status categories (out of five) by the Ministry of Education. We adopted a within-school, section-level randomization design. Within each of the 24 participating schools, we randomly assigned one of the two fourth-grade sections to the treatment group. The randomization was conducted before the collection of baseline data, and schools were informed of the treatment status of each section after the baseline was collected in March 2017.

See attached analysis plan for original pre-trial analysis submitted as part of funding application to IDRC for all details.
