TRASK GRADUATE OF THE BOSTON NORM \L SCHOOL OF GYMNASTICS INSTRUCTOR IN THE PHILADELPHIA NORMAL SCHOOL lS892> PHILADELPHIA CHRISTOPHER SOWER COMPANY COPYRIGHT, 1904 BY CHRISTOPHER SOWER COMPANY \s GrV PREFACE. IN selecting and arranging the material for this book, I have tried to meet the demand especially of those teachers who are being more and more called upon to add to their curriculum this branch of physical education, namely, gymnastics. Several years of experience in elementary grades and in normal teaching have shown what the grade teacher, as well as the normal pupil, would find essential and helpful in teaching gymnastics. A teacher's text-book to meet the general needs must be of such a nature that the simple and combined movements which it describes may be easily understood and accurately reproduced. This is provided for by definite descriptions of all movements, positions, and combinations, and by illustrations of many of the funda- mental positions. The use of technical terms is reduced to a minimum. The following series help to counteract the effects of unhygienic (3) 4 PREFACE conditions of school life and constitute, so far as the limits of the classroom will allow, a supplement to the less system- atic but exceedingly hygienic exercises found in outdoor play and games. i i/ C O X T E X T S.

(9) FIG. 1 ATTENTION. C 10) INTRODUCTION. FOR elementary school work there are practically only two systems of physical training, the German and the Swedish. The movements of these in free floor work are almost identical. One and the same set of exercises may be given in a lesson under both systems without violating the fundamental principles of either. Other so-called systems of school gymnastics are based upon one or both of these and contain nothing original excepting the selec- tion and the arrangement of the movements. Some par- ticular element or elements which appeal to the individual may have been selected and elaborated, but in general there is nothing which is not borrowed from one or both of these systems. It has been universally acknowledged that the best arrangement in general for a lesson is one in which the lesson starts with relatively easy exercises, increases to the more difficult, and ends with moderately easy ones. These lessons are composed of a number of exercises put together in a systematic way, each exercise having its special object in the lesson. The fact that the general arrangement remains the same greatly aids the class teacher in memorizing the lesson, which is an important factor, since the teacher is not a specialist and more often than (ll) 12 INTRODUCTION otherwise has had only a limited training in the work. Therefore, it is necessary to make it as easy in every way for the teacher as is consistent with the scientific arrange- ment of the subject-matter taught. The lessons must be memorized and not read from a book or card. The exercises are divideoi^i||ip : I. Introductory exercises. Order. Leg. Arm. II. Balance exercises. III. Trunk exercises. Back. Front. Lateral trunk. IV. Breathing exercises. For the sake of convenience the introductory and the trunk exercises are subdivided. The arrangement of the first ten lessons follows this general plan: Order, leg, head, arm, balance, back, breath- ing. From the tenth lesson the following is the order: Order, leg, arm, balance, front, back, lateral trunk, jump, breathing. So we have our " lesson, 7 ' " day's order," or "series of exercises, 1 ' made up of exercises which in turn are composed of two or more movements. In the first grade there is very little combination work, the combined move- ments being used mostly as "starting positions" and com- posed of easy movements which have been taken previously as "movements proper" in the class of exercises to which they especially belong. They are introduced for their INTRODUCTION 13 coordinative value and for economy of time. Since they are not usually repeated, they have very little hygienic value. The first year includes nearly all the elementary move- ments. Those following are in general a combination, in a well-defined way, increasing gradually in physical and mental difficulty. All " starting positions" follow the same order of development in the class into which they are intro- duced that was peculiar to them when previously given in their own special class of exercises. This order is likewise kept in all exercises where movements are done while the "movement proper" is held Allowing thirty weeks for indoor gymnastic work gives fifteen days' orders to each grade, each grade after the first, reviewing in the beginning of the term the five lessons of the previous year; thus the eleventh order of the first grade becomes the first order of the second grade. Two weeks' time is given to each lesson, from ten to fifteen minutes daily, but the same combination of exer- cises may be taught for one week only. This has an advan- tage over the plan of keeping a class on the same exercise two or three weeks, since under the latter condition the les- son is apt to become a set drill, the pupils anticipate the movements and the mental value of the command work is weakened. It follows also that the interest of the class is lessened. Give the "first day's order" the first two weeks; the last half of the " first" and the first half of the "second," the third week; the whole of the "second'' the fourth week; the last half of the "second" and the first half of the "third," the fifth week; etc. 14 INTRODUCTION The selection and logical arrangement of a curriculum is a most vital question with school authorities. The general principles underlying the correlation of studies must govern the arrangement of the daily program, and only by observing this law can the maximum benefit be ob- tained; only thus can the time and place for each study be correctly approximated. The program must be so arranged that one lesson is not followed by another of the same mental or physical nature, but should be followed by one of contrast, giving as much variety as possible, for in this way there is an avoidance of fatigue, which would otherwise be the result. The earlier part of the session, when the pupils are at their best, calls for the studies re- quiring the greater mental effort, and among these studies would be placed arithmetic, grammar, history, and geog- raphy. Drawing, manual training, nature studies and sing- ing might well succeed one of the above. The place for a gymnastic lesson is an open question. Some would place it with geography and history in its production of mental fatigue. Without laying undue stress upon this fact, the gymnastic lesson might well be introduced after one of limited physical activity. It is the manner in which the lesson is given which determines to a large extent the element of fatigue. When the gymnastic period is not divided, it is preferable to place it in the morning session. Under certain conditions, however, it is better to divide the time and give a lesson in the morning and another in the afternoon. The fact that gymnastics are recreative, as well as corrective and developing, must be kept in view. Formal gymnastics can never be a satisfactory substitute INTRODUCTION 15 for the recess period. Gymnastic games might be utilized during a part of the recess period with benefit. Before a lesson the windows should be opened for fresh air, when there is no other arrangement for admitting plenty. This is also necessary in order to lower the tem- perature, since a room warm enough for inactivity has too high a temperature for active exercise. It is of paramount importance to call the attention of the class leader to the fact that it would be most injurious for some pupils to take all the exercises. We have these abnormal conditions ever present which must be met and treated accordingly. They cannot be ignored, and, though the work is arranged for the average and normal pupil, those who do fall below this class must be considered. In certain cases the teacher, unless under proper direction or with proper training, should not take the responsibility of decid- ing the nature of the exercises or of giving them. It is better to omit than to commit. Children with spinal or with hip diseases, unless the exercises are definitely prescribed by a physician or specialist, should be excused. Those with marked deviation of the spine to the sides, a condition which may be recognized by unevenness in the hips or shoulder, should be excused from side bendings and twist- ings. Deviation forward, "round shoulders," should be carefully watched and manual assistance often given. In cases of "flat-foot," excuse from balance exercises when the movement is taken from one foot. Give in its place heel raising, with a very smnll or no angle at the heels. Limit or omit the "order" exercises with children who have a tendency to chorea. Call as little attention as pos- Hi INTRODUCTION sible to an excused or partially excused pupil. Unless the abnormal child is receiving special attention, under a physician's advice, it is best to consult the parent and suggest such attention. Command. There are two parts to the command, the explanatory, preceding the dash ( ), and the executive, or the word following the dash. The last word is always emphasized when it is the word of execution. The word directly before the exclamation point is the word of execu- tion, except when it is followed by counts. The tone of the voice indicates the rhythm of the movement. Hips firm! "Hips" explanatory; the dash ( ) indicates the separation, where a distinct pause must be made; "firm!" the word of execution. The word "firm" should be given in a quick and sharp tone, since the movement is to be done quickly. Head backward bend! Raise! "Bend" and "raise" are done slowly, and the voice must show this. In general foot placings, arm flingings, stretchings, and bendings, facings, march-steps and parts of the jump are given in a quick rhythm. Movements of the trunk, head, arm and heel raising and sinking, knee bending and stretch- ing, all breathing exercises and nearly all balancing move- ments, are given in a slow rhythm. There are a few exceptions, but the grade teacher will find the above rule a safe one. Pause. The separation between the two parts of a com- mand is indicated by the dash ( ), when a pause must be made of sufficient length to allow the class to do mentally what it is to do physically, upon the word of execution. The pause secures a quick and uniform response. Do not INTRODUCTION 17 allow the class to anticipate by a movement, the word of execution, else the power of control is not being trained, a factor as important as quickness of response. The move- ment is done upon the word of execution and only then. Starting Position and Movement Proper. The exer- cises are composed usually of two parts, the "starting position" and the "movement proper" of the exercise. In the lower grades the physical difficulty of the exercise is mainly influenced by the starting position. Coordination is trained in executing this position, though the hygienic value is at a minimum. The corrective value and the physiological effects of nutrition, circulation, respiration, digestion, etc., are found in the movement proper of the exercise, and these movements must be repeated the requisite number of times to produce the required results upon the part of the body to which they are especially referred. The movement proper is printed in italics. Thus, in the balance exercise of the fourth day's order, first year: Neck firm! Feet sideways place! One! Two! Heels raise! Sink! " Xeck firm! Feet sideways place! One! Two!" is the starting position. "Heels raise! Sink!" 1 is the move- ment proper. The starting position must not be held throughout the exercise, if it is of such a nature that a good position is not maintained. This is shown in the balance exercises of the ninth day's order, first year: Xeck firm and left foot forward place! Heels raise! Sink! Feet change! Etc. "Neck firm!" is a hard position for that grade to hold 2 18 INTRODUCTION well, when an exercise is given requiring a change of feet. It is better to bring the arms down before the movement is taken with the changed position of the feet. This rule is general. Combined Movements. Combined movements are com- posed of a number of single movements united under one command. They may be of like parts or of different parts of the body. Arm stretchings of the arm and foot placings of the leg are given as combined movements. Arms side- ways and upward stretch! Left foot placing forward and sideways go! Hips firm and feet close! Arms side- ways stretch, and feet sideways place! are examples of this class. The order exercises, after the "eleventh day's order," are of this kind. Many of the starting positions are given as combinations, where different parts of the body move at the same time, executed either in the same or in a different number of counts. An example of this is found in. the lateral trunk exercise of the tenth day's order, first year: Hips firm and feet sideways place! has one count for the hands and two for the feet. The rule is general that in an uneven number of counts the last count or counts take the combined movement. The teacher must keep in mind that in exercises of this kind the pause must be of sufficient length to enable the class to understand clearly the combination. The length varies with the grade, the amount of previous training, and with the difficulty of the exercise. Series. Exercises or movements in series are done by successively repeating the same, either a certain number INTRODUCTION 19 of times indicated in the command, or until some signal to stop is given. The terms "halt !" or "class halt !" are the common ones used to end a series. When "class halt!" is given, two counts at least are allowed to finish. The rhythm of the command to halt should be the same as in the series. Marching, marking time, quick time, and spring jumps belong to series work. The stimulating value of series exercise is great. They are given quite extensively in the upper grades, where the correct form of the move- ment has been previously secured. Counting. Counting may generally be used in repeating an exercise or a movement. It is in many cases desirable, not only for economizing the time, but to give variety to the commands. The time element in the class room is a very important factor. The words "repeat" or "the same" followed by the counts in the rhythm of the move- ment, may also be substituted for the words of the com- mand. Thus, in the balance exercise of the fifth day's order, first year: Neck firm! Heels raise! Sink! Raise! Sink! or Repeat! One! Two! Also in the breathing exercise of the third day's order: Arms sideways raise! Sink! With deep breathing repeat! One! Two! Always count for the breathing exercises after having first given the movement to command. Always count for the jump. It is better for the teacher to do the most of the counting in the first year; in the second and in the third years the class may count with the teacher or alone; the higher grades may work without loud counting, if their 20 INTRODUCTION sense of rhythm has been well trained. In the four upper grades it is advisable to vary the rhythm from the common rhythm of that particular movement, but in no case should it be so fast that the form is sacrificed. The time should also occasionally be changed in the lower grades, as a careful training in this is essential. Balancing an Exercise. If an exercise is unilateral, it must be balanced i. e., the same movement must be given under like conditions to both sides of the bod}-. For example, in the leg exercise of the third day's order, first year : Left foot forward place! Replace! Right foot forward- place! Replace! Left foot forward place! Replace! Right foot forward place! Replace! or, Left foot forward place! Replace! Left foot forward place! Replace! Right foot forward place! Replace! Rigid foot forward place! Re- place! Also in the balance exercise: Neck firm and left foot forward place! Heels raise! Sink! Heels raise! Sink! Feet change! Heels raise! Sink! Heeh raise! Sink! Position. The movement is usually executed with the left side, or toward the left, first, but it is well occasionally to reverse this order. For convenience these lessons are arranged, designating "left" first. The word in parenthesis (left) or (right) indicates that the same movement is to be done with that segment, in that direction, or to that side, as in the order exercise of the third clay's order, first year: 1 side step to left (right] march! or 1 side step to left- march! 1 side step to right march! INTRODUCTION 21 Formation. The greatest working space in the ordinary class-room is given when the pupils stand between the desks. The class should be arranged with the shortest ones in front. It is difficult to see the faults of the smaller pupils when they are not placed according to height. In many exercises requiring the arms stretched sideways, the hands of the neighboring pupils touch. If a diagonal formation is given, this diffi- culty disappears: "Half left face." It is necessary in giving side steps and in some of the jumps to give first "left (or right) face." For convenience the class may be faced in any direction, but it should not be kept for any length of time facing the strong light from windows. Some positions are better seen from the rear, as "neck firm," some from the side, as "trunk forward bend." Do not always teach from the front of the room; move about. Position. The word "position" is used to bring the class to the fundamental standing position from any position other than "in place rest" or "rest."' After the rest posi- tion, the word "attention" is used. The word "position" unqualified brings to the fundamental standing position in the quickest and shortest way. It is used in connection with the starting position more often than with the move- ment proper. It is usually best to bring back to the funda- mental position in the same way that the movement was taken, and therefore it is advisable, in the absence of special instruction, to indicate before the word "position," if other than the shortest way is desired. In general no such instructions are given in the lessons, but must be INTRODUCTION supplied by the teacher. This is illustrated in the balance exercise of the sixth day's order, first year: Arms sideways stretch! One! Two! Feet sidewayr, place! One! Two! Heels raise! Sink! Feet together place! One! Two! In two counts position! (Arms downward stretch !) In place rest! Always bring the class to the funda- mental standing position before giving "In place rest!'' This must be given at the close of each class of exercises i.e., between the order and the leg, between the leg and the head, etc. The rest position must not be held too long; three or four seconds are usually long enough, unless some explanation of the exercise is necessary. When a new movement is first given, or when a faulty position cannot be corrected in a few words, give the rest position, in order that the movement may be illustrated or more fully explained. Never illustrate, give a long explanation, or ask a question while the class stands at "attention," or in any position other than the "rest"' position, though short explanations in the nature of corrections may be given in the upper grades. Better results are obtained when strict mental attention and its accompanying physical positions are expected and demanded in an exercise. These cannot be given by the pupil when the teacher is illustrating, is giving a long explanation, or requires an answer to some question. The attention during the illustration should be concentrated upon the demonstration, and in order that this may be done the pupil must be free to move within certain limits, that he may see clearly. It is not pedagog- ical to insist upon a certain thing and then to make the INTRODUCTION 23 conditions such that it is impossible to accomplish that thing. What we want is satisfactory physical positions in small doses, attention in small doses. The physical "position" is the mental "attention," and both must have their quick and accurate response. Words of caution and class correction are constantly needed while the class is working. Manner. The standing position of the teacher while conducting a lesson should be an active one i. e., standing firmly upon both feet with the head in a good position ; it is not, however, a stiff attitude. The manner before the class greatly influences the power of the commands and the response to them. It is very suggestive to the class and cannot but react upon it. Preparation. The lesson must be perfectly learned and each movement should carry with it an appreciation of the feeling of such movement. This trained feeling governs the correct length of time the position is to be held, the number of times the movement is to be repeated, and it also decides the rhythm. The psychological, as well as the physiological, results to be gained from each exercise, also those to be gained from the lesson as a whole, must be kept in mind. Instruction. The teacher should be able to analyze an exercise or a movement and intelligently to develop the same from its parts. This is necessary in all new movements and in all new combinations. Besides the description, it is best to give an accurate demonstration of the movement, since by uniting the two a double association is formed, sight and hearing, the former usually the stronger of the 24 INTRODUCTION two. A practical illustration is hotter than a long explana- tion. Give all the aids which the age and development of the child demand. Distribution. \Yhen a new movement is difficult, more time may be given to it at first than is allowed later. Each has its special place, and a uniformity of time for each will result in the desired totality. Simply because the class does one exercise better than the others, is no reason why that particular one should be limited. It has its own special place and value and no other class of exercises in the lesson can be substituted. Correction of Faults. There are several ways of correct- ing faulty positions. The most general one is by class correction, "heads up!" "palms down!" "fingers close!" "heels together!" This is often sufficient in correcting a general class error, and is also used in correcting an indi- vidual, especially if the pupil is not within easy reach. It is not best in making an individual correction to indicate the pupil by name, since this has a tendency to direct the attention of the class toward the one at fault, at least in the lower grades, ("lass corrections must be given in as few words as possible. Manual corrections, where the teacher assists the pupil to a correct position, are often a necessity. The untrained muscular sense of the required position, or the physical inability to take that position unaided, are common faults. Where a majority of the class does not understand the movement, it is best to make the correction by illustration, by explanation, or both. For this purpose the class must be in the rest position. Train the eye to see and the ear to hear the faults quickly, and INTRODUCTION 25 correct the major ones first. All cannot be corrected at one time, or in one lesson, and the teacher must often be temporarily satisfied with approximately good positions. Always insist upon the best position of the head that the pupil is able to give. Have an ideal standard for all exer- cises and work toward it, but recognize the fact that there is an individual standard for each pupil which must not be ignored. It is a movable one, however, and should advance toward the ideal. p IG 2. FEET CLOSE. HIPS FIRM. (26) PART I. FIRST YEAR. 0*7) FIG. 3. HEAD BACKWARD BEND. 28 ) FIRST YEAR 29 FIRST DAY'S ORDER.

In sitting, "attention" means to sit well back in the seat, but not to lean against it, back erect, hands on top of the desk. Class stand! One! Two! Three! On " one" bring the hands to the sides; on " two," the left or right foot into the aisle; on "three," stand in the fundamental position. Order. Class attention ! brings to the fundamental stand- ing position, which is: heels together and toes turned out, knees straight, body erect, with chest high, head up and hips back, arms straight at the sides, fingers straight and close together, palms toward the body. "Class attention!" is always given after "In place rest!" to call the class to the fundamental standing position, before proceeding with the next exercise. Do not say "attention" when the class is in the fundamental position. Left footin place rest .' Place the left or right foot diagonally forward and stand at ease, but never in a lounging position. Do not give the rest position with one foot more often than with the other. "In place rest " must always be given after each exercise after the order, the leg, the head, etc. It is always taken from the fundamental standing position. 30 GYMNASTIC EXERCISES Leg. Feet close! Bring the inner sides of the foet together. In doing this, raise the balls of the feet and use the heels as pivots. The feet must not slide along the floor; the heels must be kept together; there should be as little motion of the body as possible. Head. Head backward bend! Start by pulling the chin back and then bend the head back as far as possible without relaxing the neck muscles. In raising the head, stop at the highest point. "Head backward bend" may be given in a lesson whenever it is needed to correct a bad head position. Ann. Hips firm! Place the hands upon the hips, thumbs back, fingers together, to the front and pointing obliquely downward, wrist straight and elbows back. Position! brings to the fundamental standing position. Breathing. On "one" inhale, on "two" exhale. Give this movement, always in the rhythm of deep breathing, several times. The arms may be turned, palms forward, as the breath is taken in. Class sit! One! Two! Three! On "one" place the foot toward the seat, on "two" sit, on "three" take the funda- mental position, which is the position of attention. "Rest!" is the word for ending the lesson. Sit at ease. FIRST YEAR 31 SECOND DAY'S ORDER, Order. Class attention! Left foot in place rest! Leg. Left (right) foot sideivays place! Replace! Head. Hips firm! Head backward bend! Raise!

Place the left foot directly to the left one foot length, keeping the original angle of the feet, the weight of the body equally between the feet. Foot replace! Press off with the ball of the left foot by slightly extending the ankle and bring the foot back to the original position. Arm. Arms upward bend! Turn the palms of the hand out and flex the forearm upon the upper arm, keeping the elbows close to the sides; the tips of the fingers rest upon the shoulders and in the same lateral plane. This movement in the lower grades is done in a moderately slow rhythm to insure a correct position of what might otherwise easily be a faulty one. Arms downward stretch! Stretch the arms forcibly down- ward with the fingers leading. Balance. Heels raise! Lift the heels, rising as high on the toes as possible, keeping the heels together and the body FIG. 4. ARMS UPWARD BEND. FIG. 5. XECK FIRM. 3 (33) 34 GYMNASTIC EXERCISES from swaying. Take a point as an eyemark directly in front and a little above the eye. This should be done in all balance movements. Balance exercises as such should be done in a slow rhythm, for if quickened they take more the nature of leg or of abdominal exercises. Back. Neck firm! Bring the hands quickly to the back of the neck, fingers and thumbs held as in the fundamental position. The tips of the opposite fingers just touch; the elbows are flexed to the limit and point directly to the sides, the upper arms on a height with the shoulders. Breathing. Arms sideways raise! Keeping the arms per- fectly straight, as in the fundamental position, raise slowly directly toward the sides to the height of the shoulders; both arms must be on the same level, palms toward the floor. Deep breathing one! Two! The arms will move slightly, with the breathing, but it is not best to call the attention of the class to this fact, else the movement is apt to be exag- gerated.

Stand directly behind the one in front at the correct distance, which is between the seats. This com- mand may be given whenever the class is out of alignment. Leg. Left foot forward (backward) place! Place the left foot directly forward one and one-half foot lengths, keeping the original angle of the feet with the weight equally dis- tributed between both. Backward placing is the same in the opposite direction. Be careful that the shoulders are square to the front. In replacing the foot, press off with the ball, slightly extending the ankle. 3
