Sponge techniques refer to methods used in various fields, such as art and education, to enhance learning and creativity. In art, sponges can be used to apply paint or texture to surfaces, allowing for unique effects. In education, these techniques involve absorbing information in a way that encourages deeper understanding and retention. In the context of early childhood education, sponge techniques often include hands-on activities that engage children actively. This approach helps learners to "soak up" knowledge through exploration and interaction, making the learning process more enjoyable and effective.
