Vol. VIII May, 1940 No. 3 FOREWORD Teacher training and certification in Kentucky are administered under the rules and regulations of the Council on Public Higher Echi- cation and the State Board of Education through the professional staffs of these two bodies. Curricula for the education of teachers are prescribed by the Council on Public Higher Education and approved by the State Board of Education. When these curricula have been approved, they become the basis for the issuance of certificates. The authority to issue certificates is vested in the State Board of Education through the Superintendent of Public Instruction. The Department of Education is so organized that the administrative activities relating to teacher education and certification are performed in the main through the Division of Teacher Training and Certifica- tion. From time to time it becomes necessary to issue a bulletin con- taining the rules and regulations governing the education and cer— tification of teachers. The last bulletin issued upon this question was published in January 1938. Since new developments have demandetl additional regulations during this period, T. asked Richard E. Jaggerst Director of Teacher Training and Certification and his staff to pre- pare a bulletin which would be useful to colleges and public school administrators in guiding prospective teachers in their preparation It is my hope that it may serve its purpose.

The public, fortunately, is beginning to question leadership and if that leadership is worthwhile it is accepted, but when leadership does not respond then the public, again fortu— nately, changes its leaders. Those who prepare for leadership in edcuation are learning that they will find no place in the scheme of things unless their services meet the demands of an honestly critical public. Those legally responsible for prescribing the patterns for the Preparation of educational leaders in Kentucky—teachers, principals, superintendents—are the Council on Public Higher Education and the State Board of Education, through the professional and technical stafl’s of these bodies made up of the State Director of Teacher Train- mg and Certification and the Deans of the colleges. These bodies Prescribe, not only the amount of time which must be spent in prepa- ration, but the kind of preparation necessary for each type of position, all to the end that every person who enters any position of educational Eesponsibility may do the kind of work for which his preparation best ts him. . The philosophy underlying the patterns of teacher preparation in Kentucky is quite clear. It is very easy to understand Kentucky’s e011(Z'Bpt of what the objectives of teacher education are, what the pat- tern should be, and by what standards the product should be evaluated. In brief, if a teacher meets the conditions set out in the fOHOWing Statment he will be prepared in accordance with Kentucky’s concept as expressed in her curricula: leadgirSthhe objective of teacher education is to make available functi: in» learning who have an understanding of the purposes and at the Esffof‘ education in our country, and the ability to guide Children and ex 18 e1 ent learning levels in the selection of worthwhile activities experieliicmences’ and to aid children in using their abilities, aptltudes, es, and interests toward the achievement of their life purposes. expjificnd—Th‘l teacher must have such a broad general training and Under-stanzas Will offer reasonable guarantee that he has acquired an of these in}: of the may”. problems of social life, and the implications Work D10 lems for the children whom he guides, for his fellow ers, for the parents, and for the public in general. 173 Third—The teacher must study intensely and extensively the prob- lems in those teaching areas and learning levels in which he is inter- ested, for which he has aptitude, and in which there is reasonable promise that his service will be needed. Fourth—The teacher must have learned to employ his knowledge and understandings in learning situations, and this implies that his preparation should include (1) an understanding of the problems con- nected with the growth and development of children, (2) an under- standing of the organization and control of learning programs in the school, (3) knowledge and understanding of the application of methods and uses of materials, suited to different learning level, and (4) an opportunity to integrate his own educational experiences by actual teaching under competent guidance. Fifth—Through a workable plan of pre-training selection, iii-training guidance, and followup evaluation only those persons should be per- mitted to continue teaching who manifest (1) physical, mental and emotional fitness, (2) an appreciation of the science and art of living. (3) genuine interest in teaching as a profession, (4) an understanding of the implications of education as a constructive agency in maintaining and improving our American way of life, (5) capacity for becoming effective leaders of learners, (6) an aptitude for the teaching area and school level chosen, (7) satisfactory academic achievement, and (8) adequate general scholarship. Very little has been done in Kentucky to select, in advance of college entrance, those young people who offer promise of becoming worthwhile leaders in the teaching profession. In fact no valid ' criteria have been found in any part of our country which will deter- mine, in advance, who Will and who will not be worthwhile. For that reason most of our selection of future teachers has been selection ill training, a process in which the prospective teacher and his instructors take part, and known as guidance. In the absence of adequate measures it inevitably follows that many enter the profession who are not effective. It is impossible for the state to set up standards which will guarantee that only promising persons will enter teacher pl‘epar‘ ing institutions, but this does not relieve the state of the task 0f guiding-out-of-training those who are obviously unfit for teaching- The Council on Public Higher Education has tried to set up Sud] patterns of teacher education as will carry out the concept outlined in the foregoing statement of philosophy. The same basic 0011061)t is embodied in curricula for the education of elementary teachers, secondary teachers, and for administrators of all types. The curricula are so organized that there is reasonable guarantee that the prospec' tive leader will have: 1. A general understanding of the major problems of social life through a general survey during the first two years in college! 0 174 Engli Phys 2. A hig he is any l the 1 3.

A high degree of knowledge and skill in the teaching areas in which he is interested and for which he has aptitude, and he may choose any learning area prescribed by the State Board of Education for the public schools. 3. An understanding of the problems of teaching and learning as they affect the school, the child and the teacher, which understandings embody the study of psychology and educational psychology, organi- zation and curriculum problems, testing and measuring, and super- vised teaching. THE PREPARATION OF ELEMENTARY TEACHERS The underlying philosophy of teacher education in Kentucky is the same for all types of positions in the educational field,—ele- mentary teachers, secondary teachers, principals, supervisors of learning, supervisors of attendance, special teachers and superin- tendents. General or Core Requirements for Elementary Teachers—The Principle that teachers should understand “The major problems of social life” applies to elementary and secondary teachers alike. To that end, the two-year and the four-year curricula for the education 0f elementary teachers require courses lending to this understanding. Each curriculum recognizes that there are certain learning areas which should be experienced by all teachers regardless of the t11116: spent in the total program of preparation. The fact that a two- .YeaII‘ curriculum is short is no reason why the general problems of 5001311 life should be neglected during this period. Then, too, those Who complete the two-year curriculum usually complete later a four- year curriculum at the elementary or secondary level. Teaching Fields for Elementary Teachers—The elementary curricula Provide for courses to be taken which will give training in flesfelds Which are included in the elementary courses of study. are Smelfliflstances, courses 1n general education within a learning area $605520]: ed in order that the prospective teacher will not fail to gain . nowledges and understandings in the learning fields included in the elementary course of study. Dile to the fact that an elementary teacher must lead children ence SS; many fundamental learning areas, a greater variety of experi- diiierentustt be prov1ded in his program of preparation, and due to the Spent in Ypes of experiences which he must have, the length of time some areas must necessarily be limited. :I‘Ofessmnal Preparation of Elementary Teachers—The profes- Preparatlon of elementary teachers, to a great degree, takes into sion 175 place in all phases of the curriculum, but is emphasized through the education courses. One-fifth of the work in the two-year curriculum is devoted to specific professional education and, approximately, one- fourth of the work in the four-year curriculum is devoted to educa- tion. Approximately, 80 per cent of the education requirements in the two-year curriculum, and 70 per cent of the education requirements in the four—year curriculum are made up of specified courses. Education courses are selected in such a way that they emphasize the same three phases of professional preparation as is emphasized by the education courses in the preparation of secondary teachers, namely: the psychologics, the organizatio11-1)rinciples-and—materials, and the integration phase represented by the supervised teaching experience. Educational Basis of Issuing Elementary Certificates—The Council on Public Higher Education and the State Board of Educa- tion have prescribed the specific requirements for the issuance of elementary certificates on the basis of principles outlined in this Bulletin. Two grades of elementary certificates are issued, namely: the Provisional Elementary certificate based upon a minimum of two years of preparation, and the Standard Elementary certificate based upon a minimum of four years of preparation. All the requirements for the Provisional Elementary certificate are included in the require- ments for the Standard Elementary certificate. Courses and Content—If the purposes of the Council on Pub- lic Higher Education and the State Board of Education in their p1'0‘ grams for the preparation of elementary teachers are to be truly effective, care should be given to the selection and organization of course materials and experiences. The major aspects of teacher education pattern should be considered. The curriculum for the preparation of elementary teachers includes such courses as will acquaint the prospective teacher with the major problems of social life and the implications of these problems for the teacher: English courses include Literature for Children! and Social Science courses include experiences related to govern- ment, citizenship, space relations and- the like. The minimum require' ment in Science should include from 3 to 6 semester hours in Generi11 Science. Health, Physical Education, and Safety courses should 1‘39 organized so that they relate directly to the day-to-day problems 111 these areas. _ The elementary teacher must be able to work in all the 51113399t fields included in the elementary curriculum, and to that end it has been necessary to prescribe in his program of preparation those 5111" 176 jeets with v he must no fields but h these fields mentary scl tribute to cl English, S( Writing, G1 may make 1 The pr ing of the c: Psychology, a view to programs, 2 ing learnii Elementary teaching, a expects to , 0f supervis training sci Preparatior is so organ Preparatim not constiti pI‘Ogram, 1 observation Guidir Provision f ulum mak Students i: those fields other fields Art and I encourage( ofier Oppo: social org; contribute community lgh the iculum y, 011e- educa- : in the ements phasize ized by achers, terials, caching .——The Educa- nce of in this amely: of two t based ements equire- 1 Pub- ir pro- 5 truly ;ion of ;eacher eachers ith the oblems 1dren : overn- gquire- eneral uld be nus ill ,ubjECt it has :e sub- jects with which he will have to work. In his preparation program, he must not only become acquainted with content of the difierent fields but he must learn how to select those learning experiences in these fields which may be suited to the needs of children in the ele- mentary school, and to organize these experiences so they may con- tribute to child growth. He must in his program of preparation learn English, Science, Health, History, Government, Spelling, Reading, Writing, Geography, Music, Art, Arithmetic, and the like, so that he may make them function in the total program of the child. The professional preparation should contribute to an understand- ing of the children in the elementary school. Psychology, Educational Psychology, and Child Psychology courses should be organized with a view to understanding child growth through organized learning Pl‘Ograms, and how the child may be expected to behave under chang- ing learning conditions. The course in the Fundamentals of Elementary Education should be a kind of introduction to supervised teaching, and should so be organized that the young person who ex'Pects to do supervised teaching may learn as much about the task of supervised teaching as possible before he is permitted to enter the training school to teach. Supervised teaching is the final act in the preparation of a teacher and the curriculum for elementary teachers 1s so organized that every opportunity possible is provided for his Preparation for the task. The supervised teaching experience should not constitute a radical or spectacular break in the total preparation prOgl‘am, but on the other hand should be merged with methods, observation, and participation. (filming Students in Training—The two-year curriculum makes D1'0v1s1on for 12 semester hours of electives and the four-year curric- ulum makes provision for 27 to 35 semester hours of electives. Students in training should be encouraged to take their electives in those fields in which only a small amount of work is specified and in Other fields which may contribute to better teaching. More work in figofnd MuSiC is needed. by most teachers and they should be Offer :aged to take 1t. Guiding courses. and courses in Conservation Social EPOI‘tunlties for broader servrce 1n the classroom. Courses in rganlzatlon and in mental hygiene offer much which may Contribute to teacher growth and lead to a greater understanding of 00mmun1ty Problems. 177 REGULATIONS FOR ISSUING AND RENEWING CERTIFI.

Note—The Standard Elementary Certificate is valid for teach- ing only in the elementary grades. 8. The Standard Elementary Certificate, based upon four years of college, should be valid in grades one to eight regardless of the school organization. PREPARATION OF SECONDARY TEACHERS Professional Preparation.~—It should be pointed out that the concept of what should be included in the preparation of a teacher takes the View that the three phases of the pattern (core, areas of preparation—~13rofessional training) are not separate and dis- connected but are integrated. It is assumed that during the period Of general education, when the student is familiarizing himself with the major problems of social life, he will have in mind to some degree, tl'le‘plaee of the child in the scheme of things. The social seiences~ elv10s, social organization, and the like; the sciences—biology, health and hyg’iene, and physical education, all may be studied with the teaching job in mind. It is assumed that while the student is engaged 1n 111s intense study of his major area of interest he will have the child and his needs as dominating influences. . The Child in Professional Preparation.—Professional work if 1t can be separated from the students total program, is designed to bring about an understanding of the individual. and social needs of 10:111dren, and an understanding of the effective ways of organizing “mug pl'Ogl'ams so that the needs of children may be served with the least waste. learn’l‘heSProspe-etive teacher must understand children and how they 1 - Ome of th1s understanding comes through the study of psy- :QEEy’IédOiESCGHt psychology, educational phychology, guidance, th }e ike, m the professional field, through the study of biology in e selenee field, and soeiology in the social science tield. how 3:: 113:113:01 and the Curriculum.—The teacher must understand a DI‘Og‘Iams are organlzed, the philosophy underlying the 181 school program, the nature and purpose of the curriculum, personnel relations, community life, social purposes, and the implications of all of these for children in the learning situation. He must know how to evaluate the work of the school as it attects the child, be willing, and have the freedom, to add to, or take from, the learning program as the needs demand. Student Teaching—To carry out the purposes implied in the two preceding paragraphs the Council requires that each teacher should take at least 12 semester hours of college work in such areas as the psychologies, principles, methods, organization, curriculum and measuring in the secondary school and in addition to this spend from ‘90 to 108 clock hours in laboratory experiences in which his
