 Teacher educators may participate in the in-service
 training of teachers by assisting them in the
 development and evaluation of programs and in
 helping them to recognize the relationship and
 contribution of home economics to the total school
 program.

 College subject-matter instructors and other
 specialists or consultants in home economics
 education and in related fields may be used to
 render special services in strengthening home-
 making programs by means of workshops and con-
 ferences. These services shall be planned and
 arranged by the state supervisor of home economics
 education and staff members.

3.21-3 Methods to be Used. Objectives may be attained by
 providing periodic training for employed teachers
 in refresher courses, workshops, conferences,
 seminars, and clinics which are related specifically
 to pertinent problems.

 Informal continuous in-service training is effected
 through classroom observation and follow-up con-
 ferences with the teacher, principal, and county
 superintendent; the preparation and dissemination
 of materials of instruction; directed inter-visitation
 of schools by teachers, followed by discussion and
 evaluation; individual and small group conferences
 on common problems; guiding curriculum and other
 group-study programs; advising teachers on types
 of professional improvement; professional reading
 and supplementary experiences; encouraging
 membership and participation in professional
 organizations; and guiding teachers in developing
 an effective year-round program.

 Special, short-unit, intensive, and refresher
 courses and workshops to meet professional and
 current needs of teachers may be offered by
 approved colleges, with or without college credit,
 either on campus or in the field. The state super-
 visor of home economics education, in consultation
 with others concerned, shall determine the need,
 type of course, and instructor, and shall make
 provision for this service to be offered to groups
 of teachers employed in federally-aided programs
 and in other programs having vocational objectives.
