The area formula offers limited insight for children trying to develop their area measurement reasoning skills, particularly when dealing with composite shapes. Spatial structuring, where children explore structural units of a 2D space, is an alternative approach. However, poor…

Real-world applications can be potent tools in chemistry teaching, fostering highly beneficial learning for students. By involving students in real-world phenomena, we not only alter their perceptions of chemistry but also cultivate crucial chemistry competencies, preparing them for the future as scientists and citizens. In this report, we…
