August 15, 1922 SPELLING IN NEW YORK RURAL SCHOOLS' FOREWORD Educational measurement aims at improving the educational treat- ment of children. When tests have heen given, the papers scored, and reports prepared, the first (luestions that arise are : What are we going to do ahout it ? Why were the results as they were ? How can we improve? Such questions invariahly lead to a reconsidera- tion of sul^ject matter to he used, to efforts aiming at the improve- ment of methods of teaching, and to a hetter understanding of the individual needs of children to he taught. The State Education Department is indehted to the 100 superin- tendents and 5000 teachers who gave the tests and suhmitted the results to the central office. Only through such fine, painstaking cooperation could we see the spelling prohlem of New York rural and village schools as it really is. The 204 teachers who descrihed in detail their methods and practices of teaching spelling have helped us to see certain reasons for the results achieved and have given us a guide to further endeavor. Fortunately, during the past 25 years and particularly during the last decade a great deal of experimental work has been done in the teaching of spelling. A socially worth-while spelling curriculum has been determined. Experiments have indicated and in some cases proved that certain methods of teaching gain much better results than other methods. The section of this report devoted to ' Sug- gestions for the Teaching of Spelling " has drawn freely from recent pu])lications based on experimental study. So far as possible, in every case reference has been made to the original source so that ^ Including schools in villages having under 4500 population nominally under the supervision of district superintendents. [3] the reader might find what experimental evidence justified the sug- gestion or recommendation made. Many workers have contributed to the preparation of this report. Particularly we would mention Miss Minnie D. Pitcher, a student of educational measurements in the summer session of the State College for Teachers, who very skilfully analyzed the teachers' reports of practices in teaching of spelling ; and Mr E. B. Richards, specialist in English, State Education Department, who critically read the manuscript and assisted in preparing the section on " Suggestions for Teaching Spelling." With such splendid cooperation from everyone concerned, the preparation of this report has been a real pleasure. We trust that it will prove of real use to all those who made its preparation possible. [4] A STUDY OF SPELLING ACHIEVEMENT Early attempts to use the Ayres Spelling Scale in New York rural schools showed two needs. First, the need for a test or scale which could be used to test the children of all grades in one room at a single period ; this was imperative, if the test was to be administered by the district superintendent, who, at the best, can visit each school but seldom and must do many things at each visit in addition to giving tests. Second, many superintendents wanted a test that they could put into the hands of teachers with a fair assurance that the results of their testing would be usable. As an attempt to meet these two demands, the New York State Spelling Scales- were prepared. How the Scales Were Made Three scales equivalent in difficulty have been prepared. Each scale consists of 50 words selected from the Buckingham Extension of the Ayres Scale. They range in difficulty from words so easy that more than 90 per cent of second grade children spell them correctly to words so difficult that 50 per cent of first year high school pupils misspell them. On each scale approximately 45 words are contained in the original Ayres Scale^ while the additional five words* are from the Buckingham Extension.^ The words from the Buckingham Extension were further checked against the Thorndike word list and only those included which are found in the 5000 words most used in English writing.^ For each scale, from one to three words were taken from each column C to AB inclusive — one word only was taken from the shorter columns, two or three words from each of the longer columns. The words were arranged in order of difficulty, the easiest word first and the most difficult word last. The difficulty of each word was calculated from the Buckingham Extension of the Ayres Scale, and from these data was determined the average number of words per scale that have been spelled cor- 2 Prof. William A. McCall of Teachers College, Columbia University assisted in preparing the scales. 3 Ayres Scale for Measuring Ability in Spelling (the 1000 words most used in the English language), Russell Sage Foundation, New York, N.

Bureau of Publications, Columbia University, New York, N. Y. [5] recth^ by children in the cities which furnished data for standardizing the Ay res Scale and Buckingham Extension of the Ay res Scale. These scales can be used in grades 2 to 9 inclusive, although they will proljably give best results in grades 3 to 8. Directions for Giving the Test No standardized test has any meaning apart from the conditions under which it is given. Directions for giving any test should create an atmosphere where children will be at ease and put forth their best effort without worry. To achieve such a condition directions must l)e simple, clear and so prei)ared that there will be no danger of the examiner's changing or forgetting them. To attain this latter end, examiners were required to read the instruc- tions to pupils. In order to reduce error from misunderstanding of pronunciation, a sentence was prepared to illustrate the meaning or use of each word. The examiner was instructed to pronounce each word, read the sentence containing it and pronounce the word a second time, as follows: " run The boy can run run." Directions for Scoring the Tests In order to eliminate differences of o])inion as to scoring, the following rules were ])repared : 1 Mark each word either right or wrong. 2 Where two or more s])ellings are allowed for a word by any standard dictionary, count either spelling as correct. 3 Count as wrong if the letter " t " is not crossed, unless it be a special final t construction, or if the letter " i " does not have a dot. 4 Do not give credit for spelling words not pronounced; for example, " tops " for the word " top " or " men " for the word " man." 5 If a child attempts to rewrite a word, consider the obvious intention of the child as the spelling to be scored. . Error in the use of ca])ital letters was not covered in the directions. This point needs to be adjusted in later editions of the directions sheet. Giving the Tests ^\'hen the scales were first prepared, a copy of Scale A was sent to each district superintendent in the State, with the suggestion that the State Education Department would be glad to furnish a copy for each teacher under the superintendent's direction on condition that the class record sheets be returned to the Department. One hundred thirty superintendents sent in requisitions. In some cases the. tests [6] were given by the stiperintendents during their regular visits. Other superintendents called their teachers together, generally during regular conference periods, and explained the giving of the tests, while still others mailed the scales to their teachers with instructions to follow the directions given. Papers were scored by the class- room teachers, and in many cases they were reviewed by the super- intendent who made summary reports to send back to his teachers. The class record sheets (section A containing the name, age in years, grade, and score of each child; section B. the distribution of scores by grades ; and section C, the distribution of scores by age groups) as made out by each teacher were sent by the superintendent to the office of educational measurements in the State Education Depart- ment at Albany. Tabulating the Results All class record sheets were checked to make sure that the dis- tribution on sections B and C agreed with the original entry of data on section A. Record sheets were then arranged by supervisory districts into three classes: one-teacher schools, two-teacher and three-teacher schools, and schools having four or more teachers. In making this classification, it was intended that the latter group should consist of schools having four or more teachers in the ele- mentary grades. In many instances the data at hand did not indicate clearly whether the four teachers gave their whole time to elementary grades. Doubtful cases were classed as two-teacher or three-teacher schools. This plan was followed in order that a fair comparison might be made between achievement in one-room and graded village schools having not more than two grades to any one teacher. Of course the big majority of teachers in the latter group had only one grade. What the Study Represents The tests were given in some supervisory districts as early as January and in others as late as May. The average represented spelling achievement for the month of March. The reports sent in and tabulated represent 44 counties, 85 supervisory districts, the work of more than 4000 classroom teachers, and achievement of nearly 60,000 pupils. With few exceptions the 85 district super- intendents reporting obtained results from practically every teacher in their respective districts for grades 2 to 8 inclusive. Many also sent in returns for grade 9. In other words, the averages given in this report represent spelling achievement in 76 per cent of the counties of the .State, 41 per cent of the supervisory districts, the work of approximately 30 per cent of teachers and 20 per cent of [7] pupils under the general supervision of district superintendents. It is fairly representative of spelling achievement in the rural and village schools of the State at large. In addition to the above, 4 superintendents sent in their reports after the tables were finished, and 9 other superintendents sent in summarized reports showing the grade averages for each school in their respective districts. There- fore, in all, 98 or 47. 1 per cent of the 208 supervisory districts were represented in this study. Tables 4, 5 and 6 of the appendix give the average scores by grades for each supervisory district according to the type of school. Table 7 gives similar data for the 9 districts whose superintendents sent in summarized reports, but did not send the class record sheets from their several schools. A study of these tables shows a con- siderable range in the average grade achievement of the several dis- tricts. For the one-room schools (table 4) the eighth grade averages ranged from 38.6 to 45.9. In the lower grades the range was even greater; for the third grade of one-room schools it was from 12.4 to 23.4; for the second grade it was from 5.7 to 17.2. Table 1 shows the number of supervisory districts represented in each type of school, the number of pupils tested in each type, the average scores by grades for each type of school and for all schools combined.

The Ayres standards or norms were obtained from testing approxi- mately 70,000 children in 84 cities of the United States. Since the Ayres Scale was first published, the 1000 words it contains have been incorporated into many of the newer spelling books and the teaching of them has been emphasized in various ways. It would be reason- able to expect a higher average achievement on lists of words from the Ayres Scale in 1922 than was obtained previous to 1915.^ ' Date of first publication of Ayres Spelling Scale.

With both of XpDajjoD paipds spjoAV jo jaquinu 33bj3av these factors favoring a higher achievement in New York tests, the latter's record is consistently lower than the Ayres standard in every grade and each t}pe of school. In New York, the average grade scores for one-teacher schools were lower in every case than the [10] average grade scores for two-teacher and three-teacher schools or for graded village schools ; and with the exception of grades 3 and 4. the scores for village schools were higher than for two-room and three-room schools. The combined grade scores for all New York schools tested ranged from 1.8 words to 5.2 words less than the Ayres standards. This represents approximately one-half year or grade below standard for each grade. The average grade scores for one-room schools ranged from 1.5 to 2.4 points below the grade scores for village graded schools ; or an average of approximately one-third grade below. The scores for one-room schools were approximately four-fifths of a grade lower than the Ayres standards. In brief, the average spelling scores obtained in New York schools were consistently lower than the Ayres standards for every type of school studied ; and the achievement of one-room schools was con- siderably lower than that for village schools having four or more teachers. These facts stand forth even more vividly in chart 1. Grade scores are not always a sufficient basis on which to make comparisons between different types of schools. The average age of pupils in each grade is an important factor. For those super- visory districts which sent in teachers' reports, a distribution of scores by age groups was made. Table 2 shows the average score achieved by each age group in each of the three types of schools. • Table 3 Number of pupils of each age group in each type of school Age Type of School group 4-room 2-3 room l-roor,i Total 6 289 79 293 661 7 1 162 466 1 380 3 008 8 1 991 780 2 834 5 60S 9 2 369 1 098 3 722 7 189 10 2 416 1 190 4 194 7 800 11 2 469 1 187 4 244 7 900 12 2 494 1 225 4 132 7 851 13 2 256 1 090 3 829 7 175 14 1 8S9 874 3 029 5 762 IS 1 126 494 1 781 3 401 16 332 127 325 784 17 85 39 55 179 18 6 10 - 6 22 18 854 8 659 29 824 57 337 Conclusions The number of pupils tested, the number of teachers contributing, and the per cent of supervisory districts involved give a fairly accurate picture of spelling achievement for the State's rural schools in the open country and in villages under 4500 population. In reality it presents the approximate situation for more than 300,000 children or 20 per cent of the State's elementary school enrolment. It means that New York's schools in rural supervisory districts are [11] attaining a spelling achievement approximately one-half grade or year less than American city school systems attained 7 years ago; and, furthermore, that the achievement in one-room schools is much lower than for the neighboring graded village schools having four or more teachers.
