Several studies point to the presence of a correlation between digital skills and individual characteristics, behavior, attitudes and family context. In the school context, evidence suggests a positive relationship between the use of digital devices in the classroom and students' digital literacy, as well as, in general, documenting that digital skills would be associated with better learning outcomes for children and adolescents. However, most of these studies only present results for developed countries and are limited to establishing correlations. In this sense, the present study seeks to make a relevant contribution to the literature by proposing a long-term evaluation of a large-scale intervention randomly implemented in a Brazilian state, which will allow us to investigate results both on digital knowledge and on habits and behaviors of students towards technology and pedagogical practices of teachers. The intervention involves the offer of electives of digital technologies - focused on Digital Culture - throughout the 3 years of High School in public schools of the state of Goiás-Brazil. The strategy consists of using the school teachers to implement the program, who will receive training focused on technical and pedagogical knowledge.

Primary Outcomes

Primary Outcomes (end points)
The main goal of this research is to evaluate the impact of the implementation of the program involving the offer of electives of digital technologies - focused on Digital Culture - in public schools in Goiás, with the purpose of answering some questions involving teachers and students.
With regard to teachers, what we seek to answer is what is the causal effect of Program about: (a) prioritization of teachers' pedagogical practices? (b) teachers' self-efficacy? (c) teachers' expectations of student learning? With regard to students, we especially want to understand what is the causal effect of electives on: (a) students' digital skills, habits and attitudes towards technology? (b) skills related to computational thinking, such as problem solving and planning?

Experimental Design

Experimental Design
This will be a randomized controlled trial. 60 public schools of regular secondary education in Goiás will participate in the research. This 60 schools were indicated by Education Department and paired by the researchers based on similar characteristics. Within each pair one school was randomly selected to be part of the treatment group, in which teachers will receive training to offer digital technology electives, and the other will be part of the control group. Data collection will have a baseline in early 2022 and 3 follow-ups at the end of each of the 3 years in which the digital technologies electives will be offered (2022, 2023 and 2024).
