STATUS OF CHEMICAL EDUCATION IN UTAH SENIOR HIGH SCHOOLS* H u m W. PETERSON, BRIGHAM YOUNG UNIVERSITY, PROVO, UTAH

A report of a questionnaire study indicat& the prevailing conditions and practices i n chemical education i n Utah Senior High Schools. The proport i a of students receiving chemistry instruction, the training and experience of teachers, the subjects the teachers teach, the cost of chemical education, administration of supplies and laboratory work, the teachers' problems and how a university might aid the high-school chemistry teachers i n their work, are phases of the subject sumeyed.

. . . . . .

The purpose of this study is to obtain answers to the following questions regarding chemical education in Utah High Schools: (1) How generally is chemistry being studied? (2) What has been the academic training of the teachers in chemistry, and in related fields? (3) How old, how experienced, and how recently trained, are the teachers? (4) What other subjects do chemistry teachers teach? (5) Where were the teachers trained? (6) How generally are more or less professional journals used by teachers? (7) What is the cost of chemical education? (8) What are the prevailing arrangements regarding laboratory fees, breakage deposits, length of laboratory periods, administration of supplies? (9) What are some of the problems confronting the chemistry teachers in their work? (10) How can a university aid in high-school chemical education? The method used was the questionnaire method, which, in spite of its limitations, appeared to be the only practical way of getting the needed information. A questionnaire was sent to the chemistry teacher a t each of the high schools, both public and private, which is listed by the State Department of Education, with a request that the questions be answered and returned. Data from high schools which are operated in connection with colleges was eliminated, because of the inability to separate the college facilities from those of the high school.

The schools were grouped arbitrarily into three groups: (1) schools with enrolments of 200 or fewer students; (2) schools with enrolments between 200 and 500; (3) schools withenrolments over 500, in the tenth, eleventh, and twelfth grades. TABLE I Enrolment in Chemistry According to Size of School

Nine of the 17 schools, with enrolments below 200 students, offer chemistry in alternate years, while one of the 14 schools of 200-500 enrolment, alternates. In schools giving chemistry in alternate years, the chemistry enrolment was divided by 2 to get the number enrolled per year. It will be noted in Table I that the per cent of the high-school enrolment studying chemistry is considerably smaller in the large high schools than in the smaller ones. This is probably due to an enriched curriculum in the larger schools. TABLE II Undergraduate Majors of Chemistry Teachers (39 Teachers) Undngraduolr Mqior

Table I11 shows the courses which have been studied, to some degree, by the teachers. There is a wide range in the number of courses, varying between one course and all the courses indicated. This suggests one cause of the variation seen in college classes in chemistry. TABLE N Distribution of Teachers According to Chemistry Credits (42 Teachers) No. Quorlcr Hours Credit i n Chcmisiry.

Table IV shows that about 12% of the teachers have 15 or fewer quarter hours credit, and it will be noted that the median is about 33 credits. The range is very wide. This, probably, has an effect on the quality of the courses given by the teachers. TABLE V Institutions Which Furnished Teachers of Chemistry (42 Teachers) Number of Taochns

Assuming that no undergraduate work has been done in chemistry since graduation, Table VII shows that nearly half of the teachers obtained bachelor's degrees during the last ten years, and that almost one-fifth received degrees more than ten years ago, and have done no further work in chemistry. In the light of the rapid progress being made in chemistry, it would appear very desirable for all teachers to continue their studies. TABLE YIII Teaching Time Devoted to Chemistry Perrrnlagc of

Tahle XI1 shows that the JOURNAL OF CHEMICAL EDUCATION is used by two-thirds of the teachers, and that the other three journals are used by one-fifth to two-fifths of the teachers. Tahle XI11 shows that the approximate cost per pupil of chemistry, aside from teacher's salary and the school plant, is nearly twice as large in schools with enrolments below 200 as in schools with enrolments between 20CL500, and 2.6 times as much as in schools with over 500 students. The factor(0.06) represents the interest on the investment in equipment and

Table XIV shows the distribution of schools with respect to the amounts reported as spent annually by the schools for reference books and journals for use by chemistry students. LABORATORY ADMINISTRATION

Laboratory fees are charged by 20 schools or 47.6%. Amount ranges between 50 cents and WOO. Breakage deposits are required by 22 schools or 51.4%. Amount ranges between $1.00 and $200.

In answer to the question, "Do teacher demonstrations take the place entirely of student laboratory work?" forty-one schools answered "no" and one said, "mostly, because of inadequate facilities." All require student laboratory work, with this one exception, who answered "partly." In 26 schools, 62% of the laboratory periods are single periods, mostly one hour. The other 16 or 38% have double periods. In 18 schools (43%) project method of teaching is used and in 35 schools (83%) supervised study method is used. One wonders how supervised

study method can be used effectively with the small amount of reference material obtained yearly. In 30 schools, (76%), supplies are administered in the laboratory by the teacher from a stock room; in only four of these cases was the teacher aided by an assistant. It seems to the writer to be more desirable for the teacher to be present in the laboratory supervising the study and checking the work of the students, than to stay in the stock room to do the work which a high-school boy could do. In six schools, an assistant administers the supplies from the stock room. In two schools, the Freas system is used. The topics in the A. C. S. list of Minimum Essentials are included in the courses given in 33 schools, (79%), while six (14%), said that their courses did not include them. Three schools did not answer the question. Elementary qualitative analysis is included in the courses of 16 schools, (38%) and is not included in the courses of the other 26 (62%).

* * * * Chemistry is taught as a 12th year subject in 13 schools, as an eleventh year subject in 9 schools, and a subject for mixed 11th and 12th year students in 20 schools.
