“…For example, Singh, Granville and Dika (2002) showed that math and science motivation and attitude significantly affect math and science achievement. Other researchers have also proved the positive contribution of motivation on academic achievement of different school subjects (e.g., Bipp & Dam, 2014;Froiland & Oros, 2014;Hayenga & Corpus, 2010). Moreover, various motivational constructs, such as self-concept, self-efficacy beliefs, anxiety, value and attitude have been found to affect academic achievement (e.g., Mahyuddin et al, 2006;Seaton, Parker, Marsh, Craven, & Yeung, 2014;Steinmayr & Spinath, 2009;Wolters, Denton, York, & Frances, 2014).…”
