“…Studies on student motivation have disclosed significant effects of structural characteristics of instructional tasks on student motivation (Ames, 1992;Blumenfeld, 1992). Educational researchers, psychologists, and sociologists agree that instruction will have positive effects on student learning if (a) it is based on authentic or relevant situations (Sizer, 1992), (b) it uses a wide array of students' skills and interests (Gardner, 1993), (c) it poses real challenges for students (Csikszentmihalyi, Rathunde, & Whalen, 1993), and (d) it allows for student choice or autonomy (Kahane, 1975;Passe, 1996).
