Science writing, such as lab reports, allows students to form a meaningful understanding of scientific concepts. However, students often view scientific writing as unimportant and utilize surface level approaches when completing writing assignments. The current study implemented three experimental interventions (directly-communicated, self-generated, and hybrid) aligned with prior literature and designed to improve the utility value of lab reports in college settings. Participants (n = 1,002) were recruited from 43 lab sections of an introductory biology course at a large southeastern university. Measures of subjective task value (utility value, attainment value, cost, and intrinsic value) were collected pre-, mid-, and post-intervention. The self-generated and hybrid groups exhibited higher self-reported utility value by posttest compared to the control group. Requiring students to generate their own utility value toward a task, followed by a written reflection, increases students' maintained and situational interest for biology laboratory reports.
