Well first, play-based preschools tend to be the most loosely-defined type of preschool or, at the very least, difficult to define in a meaningful way. "Play is a complex activity with many aspects, but we can list some of the characteristics of play that support learning -- free-to-fail, spontaneous, enjoyable, challenging, intrinsicall motivated, engaging, imaginative and social."
These core characteristics are what you are likely to find in play-based preschools, sometimes referred to as
child-centered preschools. Structure exists, but the focus is on play and socialization rather than academics. Lessons are carried out through play-based activities that are rooted in basic social skills like sharing, taking turns,
self-control, making friends, following instructions and getting along with others. "Playful learning can involve purposeful, facilitated, guided or free play. And, even in the latter, educators observe children's activities for educable moments that can be tied back to more structured activities as appropriate."
Comparisons are often made between play-based preschools and academic, structured preschools. The falsehood that play-based preschools often find themselves fighting against is the idea that the environment is all play and no work.
Playful learning supports academic outcomes, and also supports positive associations with learning that help children become successful, happy, lifelong learners.
Play is an especially important aspect of learning at early ages due to the plasticity of the child's brain --
however, all of the characteristics of play are key components of learning at later ages as well.
Child development expert David Elkind, in his book The Power of Play, reinforces the idea that imaginative, creative, spontaneous play goes a long way toward fostering healthy development and setting the stage for both social and academic success later. For now, in preschool, there should be a low-pressure environment that lets kids just be kids.
Preschoolers have plenty of interests -- and their attention span for a particular activity can last anywhere from a few minutes to a few weeks. In a play-based program, children choose the activities they wish to pursue based on their current interests and are offered various settings in which to carry out their play.
When it comes to evaluating a play-based preschool -- any preschool, for that matter -- parents need to think about what is best for their child's disposition, personality and propensity for learning in order to choose the most appropriate environment. Many kids will thrive in an open, play-based school, while some children might be better suited for a slightly more structured setting.
