Accurate self-evaluation is critical for learning. Calibration describes the relationship between learners’ perception of their performance and their actual performance on a task. Here, we describe two studies aimed at assessing and improving student calibration in a first-semester introductory biology course at a 4-year public institution. Study 1 investigated students’ (n = 310) calibration (the difference between estimated and actual exam performance) across one semester. Students were significantly miscalibrated for the first exam: their predicted scores were, on average, significantly higher than their actual scores. The lowest-performing students had the most inaccurate estimates. Calibration improved with each exam. By …

The purpose of the study was to evaluate the effectiveness of using a video model, graduated exposure (i.e., touch, smell, try, eat), and positive reinforcement to first increase food exploration, and then increase consumption of non-preferred foods in young children that exhibit food selectivity in a school setting. A multiple probe design across behaviors replicated across participants was used to evaluate the effectiveness of a treatment package. The treatment package consisted of a video model of each target behavior (touch, smell, try, eat) and positive reinforcement which included preferred foods and materials. The results indicated that the treatment package was …
