“…Although some previous studies did not uncover positive and significant evidence, a number did support the use of quizzes to enhance exam performance. Empirical evidence from these studies shows that quizzes (announced or unannounced) may have several instructional purposes, such as: (1) enhancing students' attendance (e.g., Hovell, Williams and Semb, 1979;Wilder, Flood, and Stromnes, 2001;Azorlosa and Renner, 2006;Azorlosa, 2011 and2012;Braun and Sellers, 2012), (2) increasing students' participation (e.g., Braun and Sellers, 2012), (3) augmenting students' preparation prior to an exam (e.g., Rusico, 2001;Marchant, 2002;Azorlosa and Renner, 2006;Azorlosa, 2011 and2012;Braun and Sellers, 2012), (4) acting as an effective feedback mechanism (e.g., Metha, 1995;Bell, 1996), and (5) improving students' exam performance (e.g., Turney, 1931;Geist and Soehren, 1997;Graham, 1999;Landrum, 2007;Kamuche, 2005 andAzorlosa, 2011 and2012). Below, we briefly present selected studies relating to these five objectives.…”
