Researchers examine whether AI improves students’ writing skills and exam-related performance while reducing teacher time constraints in grading. In schools implementing AI, teachers provided more frequent individualized feedback, and students’ essay scores increased. The evaluation is grounded in the Post-Primary Education Initiative (PPE) and an AEA RCT registration record (AEARCTR-0003729).","The Impact of Artificial Intelligence on Learning in Brazil  \nResearchers:  \nBruno Ferman Lycia Lima Flávio Riva  \nSector(s): Education, Artificial Intelligence (AI)  \nLocation: Espírito Santo, Brazil  \nSample: 178 public schools encompassing ~19,000 senior high school students  \nInitiative(s): Post-Primary Education Initiative (PPE)  \nTarget group: Secondary schools Students Teachers  \nOutcome of interest: Student learning Technology adoption Take-up of program/social service/healthy behavior  \nIntervention type: Digital and mobile Online learning Pedagogical innovation Technology  \nAEA RCT registration number: AEARCTR-0003729  \nPartner organization(s): Espírito Santo's Education Department (SEDU/ES), Lemann Foundation, [Google.org](Google.org), Oppen Social, Fundação CAEd  \nArtificial intelligence (AI) has the potential to support teachers in completing time-intensive, subjective tasks, such as grading essays, and to provide individualized feedback to students on their writing. However, evidence on whether and how AI impacts students’ writing skills remains limited. To fill this gap, researchers evaluated the learning impacts of using AI systems to score and comment on essays written for Brazil’s national post-secondary admission exam. In schools where AI technology was introduced, teachers were able to provide more frequent individualized feedback to students, and students’ essay scores improved as a result.  \nPolicy issue  \nImproving learning is one of the most pressing goals for educational policy in low-and middle-income countries. A common barrier to learning is that teachers are time-constrained and often have to juggle between providing individualized assistance to students and performing routine tasks, like grading. This is especially true for the development of writing skills, which requires teachers to spend long hours grading.  \nEducational technologies (ed techs) could help alleviate this challenge by performing the operational parts of teaching and allowing teachers to reallocate time from less to more complex tasks (e.g., one-on-one feedback to students) . For example, automated writing evaluation (AWE) systems can potentially help improve writing by using natural language processing and machine learning algorithms to predict scores and allocate feedback, thereby reducing the amount of time teachers need to spend on grading. However, there is little evidence on the effectiveness of ed techs or artificial intelligence (AI) focused on writing. Are AWE systems effective in improving students’ writing skills?  \nContext of the evaluation  \nProviding high-quality education is a challenge in Brazil, especially when it comes to language skills. According to the 2018 PISA exam, a worldwide study of students’ scholastic performance, the average 15-year-old Brazilian student scored 413 points on reading, compared to an average of 487 points in all OECD countries.1  \nIn response to the need for higher-quality education in Brazil, the implementing partner in this evaluation was launched in 2015 with the mission of improving literacy and writing skills among school-aged youth by applying artificial intelligence to linguistics in public schools. Its main product was a pedagogical program that provided feedback on writing skills to students, using an automated writing evaluation (AWE) system combined with validation of feedback by human essay graders. The AWE system was embedded in an online platform that granted students access to in-classroom practice opportunities for the essay of the National Secondary Education Exam (Exame Nacional do Ensino Médio, ENEM) .  \nENEM is the second largest college admission exam in the world. It has been increasingly used as an entry exam by many postsecondary institutions in Brazil, and the essay portion of it accounts for the largest share of the public-private school achievement gap in ENEM scores.
