“…Astin (1993) reported that the quantity of time spent studying and doing homework had significant effects on more than twothirds of their 82 outcome measures, such as retention, graduating with honors, enrollment in graduate school, standardized test scores, and all self-reported increases in cognitive and affective skills. However, others have questioned whether or not the amount of student preparation or study influences certain aspects of student's performance (Erekson, 1992;Schuman, Walsh, Olson, & Etheridge, 1985). These and other studies (e.g., Britton & Tesser, 1991;Lahmers & Zulauf, 2000) question a simple or direct relationship between student effort and their performance or grades, but do not negate the influence of student effort, possibly interacting with other variables, on forms of learning.…”
