Small class children
For small class children's scientific observation and recording, teachers should take systematic and direct participation guidance to drive, inspire and encourage children to participate in observing and recording scientific discoveries.
Middle class children
Teachers can let go appropriately, give timely guidance according to the problems in children's exploration and recording, and encourage children to explore and record independently. Teachers can also organize and guide children to exchange and discuss recording problems.
Large class children
Teachers should give full trust and performance opportunities, and let children complete experimental observation and recording in groups or independently. Teachers can participate in children's experience sharing activities in stages to help children sort out and improve their experiences, thus guiding children to further observe and record.
