Our Beliefs About Science Education & Young Children Early childhood teachers build on the sense of wonder present in all children. Young children learn about science through play. Doing science comes naturally for young children. The science processes that young children engage in are more important than learning science facts. As children engage in science experiences, adults observe childrens actions and listen to their conversations so that they can follow childrens leads.
The ABCs of Science in ECE Science processes occur in all parts of the classroom and outdoors, not just at the science table. Children are intrinsically motivated when they have materials to enjoy, have some control over their learning, and enjoy success when involved in science processes. Children and adults should feel free to engage in science processes, understanding that exploration is more important than right or wrong answers. A primary role of the Early Childhood Science Teacher is to provide an appropriate learning environment and opportunities for children to explore, represent, and share their discoveries. Children learn best when they have their own science materials to explore.
The ABCs of Science in ECE Trial and error, cause and effect are natural parts of the scientific learning experience. Science activities and materials need to be culturally relevant and part of a childs every day world. Every child, regardless of gender and ability, needs to have equal access to science experiences. Young children with disabilities are best served in classrooms where they are involved in science processes along with typically developing peers. Adults need to model excitement and enthusiasm when involved in science processes and when planning and anticipating discoveries.
The ABCs of Science in ECE Children who engage in active learning in ECE programs are more likely to succeed in school and in life than children who attend more teacher-directed programs. Peer modeling, lively interaction, and conversation are essential parts of the ECE science curriculum. When talking to children about science, it is important to honor their choice of words. In ECE classrooms, there should be a balance between child- initiated and teacher-initiated science activities. Effective ECE teachers must be effective parent educators who involve families in their childrens science activities.
The ABCs of Science in ECE Teachers cant give children wonderful ideas; Children need to discover or construct their own ideas. Developing new concepts or ideas is an active process and usually begins with child-center inquiry. Child-centered inquiry focuses on the asking of questions relevant to the child While inquiry involves a number of science related skills, the focus is on the active search for knowledge or understanding to satisfy curiosity
The ABCs of Science in ECE Traditional Approach Science viewed as already- discovered knowledge Teacher viewed as authority Areas of study set by teacher Large group instruction and investigating Evaluation based on right answers Content not connected to childrens experiences Predetermined parameters around areas of study Prescribed ways to collect and record data Science viewed as separate area of the curriculum New Approach Science viewed as active exploration Teacher viewed as facilitator Areas of study set by child interest Individual and small group investigations Evaluation based on multiple criteria Content connected to childrens experiences Content of study open-ended Multiple ways to collect and record data Science integrated with other curricular areas

Sampling of Science Goals Content – Body of knowledge representing what we know about the world – Develops and increases over time – Desire to communicate and represent their knowledge and should be acknowledged and supported Processes – Active component of science – Include predicting, observing, classifying, hypothesizing, experimenting, communicating – Adults should show a sincere interest in childrens observations & predictions – Adults should provide a variety of materials and settings that invite experimentation Attitudes and Dispositions – Curiosity; Drive to Experiment; Desire to challenge theories & to share new ideas – Teachers should: Value these attitudes or dispositions Be aware of how they are manifested in young children Find ways to acknowledge and nurture their presence
Teachers Role in Science Education Teachers attitude toward science is perhaps the most crucial factor. Two prevalent roadblocks Select appropriate activities – Allow child to be the cause of the action and employ a hands-on approach – Permit child to observe the results of their actions on objects – Select activities where the change is rapid and observable
