This teacher resource guide is an instructional resource for these three separate courses: exploring education careers, elementary school teacher assistant, and elementary school teaching internship. (Exploring education careers is designed as a field-based internship that provides students a background knowledge of child and adolescent development principles and principles of effective teaching practice; they work under the direction and supervision of career educators in direct instructional roles with elementary, middle, and/or high school-aged students. Elementary school teacher assistant and elementary school teaching internship are designed as work-based internships that provide students learning experience in child development while they work directly with young children and career elementary school teachers.) Contents include the Texas Essential Knowledge and Skills (TEKS) crosswalk with the three courses; sample block plans; instructional strategies in nine sections, each containing a topical outline, notes column, and suggested resources; blended activities; creative ideas; lists of 17 resource organizations, 18 print resources, and 36 web sites; and 107 teaching aids. Section topics include school district and campus management, school environment, growth and development of young children and adolescents, learning opportunities, parent and community involvement, careers, employability skills, and supervised career-connections experience.
