Abstract

The study of shadows is a common elementary science topic that facilitates students’ development of
understanding about light and associated waves. All elementary students have observed numerous shadows, but
need assistance in developing understanding. Previous research studies about shadows were utilized in
organizing aspects associated with shadows. This review paper encourages teachers to utilize three principles of
learning: students’ prior knowledge about shadows, factual and conceptual knowledge related to shadows, and
metacognition requiring students to think about their personal understanding about shadows; thereby, promoting
students’ science literacy.
