Resources and Research

Here at Merry Lea, we work to support regional educators, local organizations and local school districts to deliver high quality environmental education to preschoolers and kindergarteners. We are a nature school host, but also train and encourage participating schools to utilize the outdoor spaces on their school property.

We believe nature-based early childhood education (NbECE) is a powerful tool to help children to grow, learn and develop. We want to get that tool into the hands of educators in our region.

We support teachers and administrators on their own journey of discovery and implementation in the following ways:

Professional Development: trainings and observations

Program design and implementation

Written program resources

A curated list of research

Past Opportunities:

  • Taking School Outside: A Teacher Workshop on Forest Kindergartens and Nature Preschools: Forest Kindergartens and Nature Preschools are a growing movement nationally and right here in our state. This virtual workshop was open to educators interested in understanding the research, pedagogy and approach within these programs.

Program Design and Implementation

We work with schools to adapt, create and implement nature-based practices or programs that get their students learning outside! We encourage schools we work with to consider:

  1. How families and the community can be involved as critical stakeholders. Families and community partners can be engaged in supporting student success through regular updates, engagement as active participants and many other contributions.
  2. How their NbECE program should be structured to meet its stated goals. This may influence the location of the program, its frequency or program elements.

Recognizing that each school’s needs and settings are unique, our partnership models are flexible and individualized. We provide varying degrees of implementation, from a 3-year track model to a consultation model. No matter the type of partnership, we want to support educators in adapting and designing NbECE into their settings. We are a resource for training, philosophy development, classroom connections and other support as needed.

Regional and National Research on NbECE programs

Programs in Indiana and Michigan

  • National survey (NAAEE, 2017) listed less than 5 recognized NbECE programs in the state of Indiana.
  • Regional survey (Proctor, 2020) identified only 10 programs in the Northern IN/Southern MI region that self-identified as being a NbECE program, or having elements of NbECE as part of their program.

Benefits of NbECE: Children benefit when given access to the outdoors. 

Benefits of NbECE: NbECE provides high-quality, developmentally-appropriate nature-based programs.
