and the placing together of these common characteristics to form the general idea. Moreover, not the teacher but the pupils must do it. The question arises, "How?" Certainly not by an elaborate formal process. This is just the error found in many lessons; the pupils are made to lay bare the mental process by which they arrive at the general idea, and that is exactly the thing they cannot do. It leads to the often-heard remark, "I can do it for you but I cannot tell you how." There are two ways for them to show that they have made the generalization: One is to express the general truth in words; the other is to use it. Unfortunately, the common practice of teachers of mathematics is to insist too soon and too much upon the first way. They present particular cases of some general idea thoroughly and then ask for "the rule", as evidence that the pupils have grasped the idea. The expression of the idea in words is, as a matter of fact, difficult for children. As opposed to this plan, there is the preferable alternative of permitting the pupils to show their grasp of the idea by using it. McLellan and Dewey have expressed this thought well in their "Psychology of Number" in the words, "The natural psychological law in all cases is first the use of a process in a rational way, and then, after it has become familiar, abstract recognition of it." This quotation should be placed by every teacher of elementary and secondary mathematics, where it will be a constant reminder and guide in his or her work.

Formulation. In order to emphasize still further the thought contained in the latter part of the preceding paragraph, it seems wise to consider the expression of the general truth in words or symbols a separate stage of the lesson. After the idea is familiar, it should by all means be given some brief expression as an additional means of fixing it upon the minds of the pupils. The pupils should be encouraged to express this rule or relation themselves; when some definite form of expression is desired, the pupils should be led to the point where, if possible, they can give it. Aside from the educational value of such training, the opportunity of arousing interest in this way is great.

Application. There remains now for the teacher only the task of fixing the idea in the minds of her pupils. This is the drill stage of

the lesson, where, by repeated use, the idea is made increasingly clear. Here it is important to remember that an abundance of carefully graded, simple exercises are more effective for drill purposes than a few relatively more complex exercises. There is no implication that no new thoughts will be introduced in the application stage. Quite the contrary. Since it is wise to limit the first instruction on any new idea to the first essentials of it, the fine points should be given during the application stage, if at all.

Summary. The five stages of the lesson will now be repeated.

1. Preparation of the minds of the pupils for the new idea. Make it brief.

[blocks in formation]

It is one of the special advantages of mathematics that it lends itself to this mode of instruction. The truths of mathematics are separable into simple portions, each of which can be presented through easy steps which are within the comprehension of the pupils and from which they can generalize. The pupils delight in such work, and rarely complain then that they do not see what the teacher means. It is worth mentioning that some of the criticisms of mathematics made in the past have proceeded on the assumption that it is taught deductively rather than as outlined here; hence the statement that mathematics has small educational value as it does not give training in weighing and balancing situations and in generalizing. The fault is not in the mathematics but rather in the manner in which it is taught. Elementary mathematics should be taught inductively for every sound pedagogical reason that can be advanced, and being so taught, is not subject to some of the criticisms made of it in the past, to which great weight has been attached. More

over, lest it should not be clear, "elementary of all-one that is constantly used in the future mathematics" includes not only arithmetic but work of the course, will be taken up on that day. also algebra and geometry.

Application of this Theory

Assume a desire to A lesson in geometry. teach that the vertical angles made when two straight lines cross each other are equal.

We shall assume that the class has learned how to use the protractor to measure angles and of course that they know the meaning of angle and straight line.

Preparation. Little will be needed unless the pupils have not used their protractors for some time; in that case, the lesson might start with the statement that the children must be able to measure an angle with the protractor in order to solve the problems in the teacher day's lesson, after which the might make certain of it by having them measure an angle. Next the idea of equal angles might be recalled. The problem might then be proposed, including the idea of opposite angles.

Presentation. Draw two straight lines crossing at a convenient angle; have the opposite angles measured and the angles compared. Do likewise for the other pair of opposite angles in the figure. Do this for at least two such figures.

Generalization. Draw two lines making an angle of 60°; ask the pupils the size of the opposite angle; also of the adjacent angle and its opposite angle. Do this possibly for two or three particular cases, including such as, "Draw two lines making an angle of n°, etc." Also include such questions as, "If the angle is any size, how does the opposite angle compare with it?"

Formulation. Have the general truth expressed in words.

Application. Give some applications of the

idea.

Note. This is a lesson for a grammar school class. For a high school class the same plan might be followed to advantage, only there it could be briefer, and, following the stage of generalization, would come the customary deductive proof.

A lesson in algebra. Assume a desire to teach the method of multiplying (ax+b) by (ex+d).

Preparation. The pupils will have had other type forms of multiplication so that the only introduction needed will be a statement to the effect that another form, the most important one

Presentation. Have the pupils work out by long multiplication three or more of the following problems, and write down the results as given below:

(2a+5) (3a+4)=6a2 +23a+20.

(5t+7) (4t+3=20t2 +43t+21.

(7x+1) (3x-5)=

After the pupils have obtained two or three in the long way, individuals should be encouraged to try to do the work mentally. Having had such work from the first part of the term, there will be a number who can quickly find the first and third terms of the product and will be able to tell how they do it. The teacher will have to assist the majority of the class to find the manner of determining the third term mentally.

Note. This may take all of one lesson.

Generalization. Have other problems solved mentally and checked up by long multiplication until the pupils all know the process.

Formulation. Have the process expressed in words, if that seems wise, or have the class learn the rule often given in books.

Application. The usual drill.

Deductive demonstration. The deductive demonstration, often given in the algebra as the very first introduction to this process, should be given about now, if at all in the first year.

Most College Graduates Enter The Teaching
Profession

A summary of thirty-seven representative
colleges of the United States shows that teach-
ing is now fhe dominant profession of college
graduates, with 25 per cent; business takes 20
per cent; law, which took one third of all the
graduates at the beginning of the nineteenth
century, now claims but 15 per cent; medicine
takes between 6 and 7 per cent, and seems to
be slightly on the decline; engineering is slowly
going up, but still takes only 3 or 4 per
cent; while the ministry, with its present 5 or 6
per cent of the total, has reached the lowest
mark for profession in the two and a half cen-

2. If you haven't attained that degree of success to which you seem to be entitled, go to meet those who may be able to enlighten you as to wherein lies your deficiency.

3. If you are successful in dealing with a certain problem, go, take part in the discussions and give others the benefit of your experience. Go to get inspiration that will make you want to keep on trying to make a success of your work.

6. Go, keep up with the progress of the profession or you will eventually lose out.

7. One ought to be an enthusiast over the profession of education first and then over her particular phase of it, be she a primary teacher or a university president.

Why Children Liked Their Teacher
She could stand some fun.
She had no "pets."

The children feel as if she was one of them.

The principal reason I liked her was because she liked me and showed it once in a while.

If you did not get your lessons, she Was SO sorry that it made you ashamed.

She took a great deal of interest in us.
Put us on our honor.

She never punished the pupils because she didn't feel good.

Never flew off the handle.

Does not scold us one time, and then be awful good for a while.

Always meant what she said.

She made things pleasant, so I felt like working.-Selected.

Suggestions

I. If you haven't already done so read in the June number of this Journal "Art in the Public Schools of Madison" by Harriet F. Estabrook O'Shea and "The Ideal Kindergartner in her Relation to Children" by Ruth Waterman Norton. The former contains some practical suggestions that may be made use of in any community. The latter is well worth reading. If you favor kindergarten work, read it. If you do not favor it, read it. If you are a kindergartner, read it.

II. Familiarize yourself with the "World's Chronicle." (358 Dearborn St., Chicago.) It is just the paper for the busy teacher. It is an inexpensive record of what our nation is doing and what is going on abroad. It contains material for all grades. It will help you with your work in civics and ethics.

III. Have you arranged your permanent program and placed it where your pupils can see it? This is the second month of school, you know.

IV. Have you found out some good things about the boys and girls in your school? This is a good time to report it to fond fathers and mothers. They will approve of it and incidentally perhaps "approve" of you.

V. Spare a little time from reading, writing and arithmetic to be an inspiration to your pupils in good morals, and habits of health.

VI. We hear much about dramatization in the first three grades. Why not more of it in the upper grades? What possibilities in history, geography, and literature! The Journal would like to hear from anyone who has experimented with this work.

VII. Are you teaching "ugh" and "thugh” and "tugh" for "a" and "the" and "to"? Stop it. (Read P. 349, American Journal of Education for May, 1911.)

1. Do you think I ought to keep written "plans"? Yes. You will be sure to plan your work more carefully if you get into the habit of making written notes. Your notebook will be helpful also as a record of work done,

2. To what extent should spelling and penmanship control the marks given a pupil, in g ography, for instance?

A geography examination should be a measure of geographical knowledge only.

3. Why is less emphasis being placed upon teaching the effects of narcotics than formerly?

The "effects" appear too far in the future to have much effect upon the average pupil. The primary purpose in all phases of work in physiology should be to lead pupils to a practical knowledge of the laws of health including hygiene, foods, and first aid to the injured, 4. How may I best teach "distance"?

Give considerable practical experience with ruler and tape. Estimate distances and correct by actual measurement.

5. If I begin the teaching of reading by the sentence method, how long is it advisable to use it exclusively?

As a rule teachers cannot carry the sentence method to advantage longer than six weeks, then supplement it by the word method, In another six weeks rely to quite an extent for the recognition of new words upon some simple plan in phonics. While doing analytic work, however, keep the interest mainly on the thought.

6. What bulbs are best for me to put out this fall? Try daffodill, crocus, hyacinth, and snowdrop. Set out this month and you will have the blossoms before school is out in the spring.
