The goal of this study was to investigate if participation in collaborative professional development workshops - on learned helplessness, self-efficacy, and metacognition - would impact teachers' beliefs in their capacity to address students' helplessness. The underlying assumption was that, with deeper understanding of the theoretical background upon which instructional practices should be constructed, teachers would develop a stronger belief that, through their pedagogical practices, they could impact students' individual learning outcomes as well as the classroom environment. In order to achieve this endeavor, an eight-week intervention was conducted in a low-achieving and low SES public school in Rio de Janeiro, Brazil.

The study's design, development, implementation, and evaluation were oriented by guidelines derived from the formative and design experiment methodology. The study benefited from quantitative and qualitative data collection and analysis methods. Triangulation of data showed strong consistency between quantitative and qualitative findings. After the intervention, participating teachers acknowledged implementing the theories in their classrooms.

Reported impacts included (a) strengthened teachers' beliefs about their capacity for effective teaching in this school environment; (b) increases in teachers' instructional efficacy and metacognitive abilities; (c) increased capacity to exercise reflective practice through evidence- based self-evaluations; (d) increased capacity to create comprehensive lesson plans including the Nine Events of Instruction (Gagne, 1985), the MUSIC Model of Academic Motivation (Jones, 2009), and metacognitive strategies (Schraw, 1998). As teachers implemented the strategies in their classes, they reported positive impacts on the students' interests, attitudes towards classroom activities, and efforts to achieve.
