Practice Without Feedback: A Better Option?

Fyfe and Rittle-Johnson (2017) studied the effects of feedback on immediate and 1-week delayed performance of mathematical skills. The study participants included 243 second and third grade students. All students took a pre-test, received scripted instruction, practiced mathematical problems, and demonstrated skill proficiency on a post-test. Students were retested one week later to study knowledge retention of the learned mathematical strategies. During the practice phase of the study, students either received immediate feedback after each practice problem, summative feedback after all the practice problems, or no feedback at all. Results of the study showed that immediate feedback resulted in the highest performance during the practice phase of learning. Practice with no feedback correlated with the highest levels of mastery (students scoring 100%) on the 1-week knowledge retention test (Fyfe & Rittle-Johnson, 2017).

These finding suggest that while immediate feedback may increase initial performance on practice problems, practice without feedback may have a stronger longer lasting effect on learning. In addition, summative feedback (feedback after all practice problems were complete) had an insignificant effect on performance on both the post-test and the 1-week knowledge retention test. The findings imply that the most effective feedback during practice for student learning and knowledge retention is either immediate or no feedback at all. While immediate feedback had a immediate positive effect on practice problem performance, there was no significant difference of performance on the post-test for students who received feedback versus students who received no feedback. This study was limited in that 45% of students showed mastery (100%) on all tests and may not have needed feedback to help them master the mathematical concepts presented (Fyfe & Rittle-Johnson, 2017).

The feedback offered in this study was restricted to correct or incorrect validation. Students were not encouraged to revise their work with the correct answer or defend their reasoning of the mathematical concepts. I am curious how feedback with time for revision work may affect performance on the 1-week knowledge retention test.  

The study raises complicated questions about which students benefit from feedback during practice and which students benefit from practice without feedback. In my own fourth grade classroom, I can picture a few students who already have a basic understanding of fourth grade mathematical concepts and strategies. These students may benefit most from practice without feedback. While this may not feel immediately effective, it could have a positive long-term effect on their learning. Other students who do not have background knowledge of our fourth grade mathematical strategies may benefit from immediate feedback during practice. Based on this study, I do not think that summative feedback (feedback after a full set of problems) is the most effective feedback that I can offer my students, nor is it a practice that I want to include in my feedback research study.
