A major focus of research on teaching and learning for the past decade has
been directed toward developing an understanding of student behaviors and t
hought processes related to achievement. Using a mediational-processes appr
oach, researchers have identified engagement Variables that predict skill l
earning gains, most notably the quality and quantity of practice and studen
t self-perceptions of efficacy and competence. We sought to extend this cor
relational research by examining how one aspect of instruction, task progre
ssions, influenced students' practice quality and task-related cognition. U
niversity students enrolled in tennis classes were taught and practiced the
serve under one of three conditions, two characterized by easy-to-difficul
t task sequences, and the third involving practice of the criterion task. D
ata were collected on students' practice trials and three task-related cogn
itions: motivation, self-efficacy, and perception of success. The results i
ndicated student practice and task-related thoughts varied according to ent
ry skill level and the condition under which they practiced. Instructional
conditions involving easy-to-difficult progressions resulted in more succes
sful and appropriate practice trials and enhanced student self-efficacy and
motivation. These findings parallel those previously reported on the impac
t of student ability on practice quality and add to an understanding of how
instructional conditions affect what students think and do in physical edu
cation class contexts.
