A dynamic and diverse workforce of agricultural professionals and scientists is needed to develop sustainable and innovative solutions for the challenges of food production for a growing population under the threat of climate extremes. One path to developing workforce talent is through summer research and extension experiences. The Applied Plant Systems (APS) Research and Extension Experiences for Undergraduates (REEUs) program provided 23 undergraduates a pathway to work with agricultural science, technology, engineering, and mathematics through plant and soil sciences research and extension programs. To develop the professional skills of interns and guide self-reflection, weekly Think Tank Sessions were organized to focus on teamwork, time management, decision-making, and systems thinking. To assess variation in the students' approach to their work, the Approaches and Study Skills Inventory for Students (ASSIST) was incorporated into program evaluation. Using a pre-post design, students' agreement with statements reflecting a deep, strategic, or surface approach to their work was measured. T-tests revealed significant increases in mean scores for subscales measuring Deep Approach, one subscale measuring Strategic Approach, and the subscale measuring fear of failure to reflect the Surface Approach. Increased fear of failure scores may be explained by new experiences working with research, peers, and mentors. Eight of 23 students who participated in a follow-up survey after the conclusion of the program reported increased knowledge of agricultural careers. Results provided evidence that the APS experience increased student confidence in facing challenges that require deeper and strategic thinking and elevated their attention to monitoring the effectiveness of their decisions and skills.
