“…While there are many possible factors contributing to this trend (e.g., school, family, peers), it is argued that the most proximal factors influencing achievement, that are of educational and psychological importance, are those related to processes taking place in schools, classrooms and students themselves, such as teaching strategies as well as students’ motivation to learn. More distal factors, such as the structure of the educational system or the national curriculum, are typically stable and beyond the influence of students and teachers in centralized governing systems, such as the Greek one ( Kougias and Efstathopoulos, 2020 ). The psychological processes, though, that are under the explicit control of the learners are malleable to change ( Winne and Nesbit, 2010 ), and, thus, susceptible to psychoeducational interventions.…”
