Two-Tier Instant-Feedback Assessment Strategy for Improvement of Student Concentration.

In this study, a two-tier instant-feedback assessment model was constructed using the Zuvio instant-feedback system and oral questions; this model was applied to conduct formative assessments for an introductory computer course. We adopted a one-group pretest-posttest approach with 52 first-year nursing students. The course ran for 6 weeks with two classes per week. The course content of mBlock language and the educational robotic kit mbot was introduced in the first 2 weeks. From the third to the sixth week, the two-tier instant assessment strategy was added. At the end of the teaching experiment, surveys on concentration and course satisfaction were administered. Our results were as follows: (1) two-tier instant-feedback assessment can enhance student concentration, as the results showed that students' concentration improved; (2) in the subscale, the "competitive selection" dimension reached a significant difference; and (3), the students held positive views toward the incorporation of two-tier instant-feedback assessment into the course.
