Developed for use by teacher educators or state staff, this teaching packet provides preservice or inservice training to teachers and prospective teachers on how to use the Illinois Core Curriculum in Agriculture. (It is recommended that copies of the Illinois core materials be available to the students.) Three problem areas are included: Orientation to the Illinois Core Curriculum in Agriculture, Using the Core Curriculum to Develop a Teaching Plan, and Using the Core Curriculum to Develop Courses of Study. Each problem area includes all or most of the following components: teacher educator's guide (suggested objectives, suggested interest approaches, anticipated problems and concerns, suggested learning activities, application procedures, evaluation, and references), information sheets, worksheets, transparencies, and class handouts. The recommended time for teaching these problem areas is during the "methods" course prior to the student teaching experience or as part of an inservice workshop or seminar for teachers currently employed.
