This manual contains an outline of a 4-day teacher training workshop focusing on environmental education at the early childhood level. The overall purpose of the workshop is to stimulate the infusion of environmental education into early childhood programs as a way of fostering in young children an understanding of and appreciation for the natural environment. The format of the workshop represents a hands-on process approach to learning and is based on a problem-solving and investigative instructional approach. The workshop is designed to be implemented over a 4-day period with a 1-day follow-up session scheduled several months after the initial sessions. During the interim, workshop participants are expected to develop and field test an instructional unit with an accompanying activity kit that is to be shared during the follow-up session. This includes introduction, rationale, and purpose and objectives; overview of the workshop; designing the workshop; publicity and recruitment; application and confirmation; workshop outline; additional ideas; time line for participants' responsibilities; evaluation; references; and additional resources. Appendices include funding proposal for the workshop, bibliography of books relating to trees, Project Learning Tree bibliography, storytelling for all ages, and Life Lab curriculum. (JRH)
