“…Indeed, authors such as Topping (Topping and Whiteley, 1993;Shanahan et al, 1994;Topping et al, 2011;Topping, 2019), Fuchs (Fuchs et al, 1995, 2019;Powell and Fuchs, 2015), and Ginsburg-Block and Fantuzzo (Fantuzzo and Ginsburg-Block, 1998;Ginsburg-Block et al, 2006;Can and Ginsburg-Block, 2013), among others, have been studying the academic, social, and psychological benefits of peer tutoring in mathematics and other subjects for more than three decades. The positive effects of this cooperative learning strategy on variables such as self-concept, attitude toward mathematics, selfesteem, and social integration have been repeatedly documented (Alegre et al, 2020;Moliner and Alegre, 2020). Nevertheless, in spite of the broad range of literature that exists regarding peer tutoring, very few studies have addressed the effects of this methodology on students' mathematics anxiety.…”
