“…In the context of pre-service teachers, authors noticed that some students of the bachelor's degree in primary education present low levels of mathematics teaching efficacy beliefs and a negative attitude towards mathematics (Boaler, 1997;Bursal, 2010). Literature research supports the importance of enhancing the pre-service teachers' mathematics teaching efficacy beliefs (e.g., Bursal, 2010;Moody & DuCloux, 20015;Yang et al, 2020) and their attitude towards mathematics (e.g., Hourigan & Leavy, 2019;Michaluk et al, 2018), and how these factors influence to the mathematics academic achievement (e.g., Charalambous et al, 2009;Leavy et al, 2017;Ma & Kishor, 1997). As pointed out in Hannula (2012), it is still important and interesting to investigate the impact of variables concerning teachers' mathematics related effect on other affective or cognitive variables such as academic achievement.…”
