First grade students reading, mathematics, and learning analytics scores obtained in a randomized controlled trial during the COVID-19 pandemic school closures with children studying alone at home

This file provides the dataset of a randomized controlled trial conducted in Brazil in 2020, during the COVID-19 pandemic. As schools were closed, a group of 2,980 children received access to the Escribo Play instructional app. The students did gamified pretests to assess their word reading and early mathematics skills. The randomly allocated experimental group played a sequence of 20 early mathematics games while the control group played a sequence of 20 early literacy games. After the instructional games, students did the gamified reading and mathematics posttests.

本文件收录了2020年新冠疫情期间于巴西开展的一项随机对照试验（randomized controlled trial）的相关数据集。彼时当地学校因疫情停课，共计2980名儿童获得了Escribo Play教学应用的使用权限。参与研究的儿童首先完成游戏化预测试，以评估其字词阅读与早期数学能力。研究通过随机分配将受试者分为两组：实验组完成共计20款早期数学游戏的游玩任务，对照组则完成共计20款早期识字游戏的游玩任务。教学类游戏环节结束后，所有受试者再次完成游戏化阅读与数学能力后测。
