That any rational and accountable being should ever have been found to oppose the progress of truth, is truly humiliating; yet every page of history, which records the developement of new principles, exhibits also the outbreakings of prejudice and selfishness. The deductions of Galileo, of Newton, of Harvey, and innumerable others, have been opposed and denounced, each in its turn; while their promoters have been vilified as empyrics or innovators. Nor has this been done by those only whose self love or worldly interests prompted them to exclude the truth, but by good and honourable men, whose prejudices were strong, and whose zeal was not guided by discretion. Such persons have frequently been found to shut their eyes against the plainest truths, to wrestle with their own convictions, and positively refuse even to listen to evidence. The same thing may happen with regard to education;—and this is no pleasing prospect to the lover of peace, who sets himself forward as a reformer in this noble work.—Change is inevitable. Teaching is an art; and it must, like all the other arts, depend for its improvement upon the investigations of science. Now, every one knows, that although the cultivation of chemistry, and other branches of natural science, has, of late years, given an extraordinary stimulus to the arts, yet the science of education, from which the art of teaching can alone derive its power, is one, beyond the threshold of which modern philosophy has scarcely entered. Changes, therefore, both in the theory and practice of teaching, may be anticipated;—and that these changes will be inconvenient and annoying to many, there can be no doubt. That individuals, in these circumstances, should be inclined to deprecate and oppose these innovations and improvements, is nothing more than might be expected; but that the improvements themselves should on that account be either postponed or abandoned, would be highly injurious. An enlightened system of education is peculiarly the property of the public, on which both personal, family, and national happiness in a great measure depends. These interests therefore must not be sacrificed to the wishes or the convenience of private individuals. The prosperity and happiness of mankind are at stake; and the welfare of succeeding generations will, in no small degree, be influenced by the establishment of sound principles in education at the present time. Nothing, therefore, should be allowed to mystify or cripple that science, upon which the spread and the permanence of all useful knowledge mainly rest.

The art of teaching grew up in the schoolroom, out of inventiveness and sympathetic concrete observation. Even where (as in the case of Herbart) the advancer of the art was also a psychologist, the pedagogics and the psychology ran side by side, and the former was not derived in any sense from the latter. The two were congruent, but neither was subordinate. And so everywhere the teaching must agree with the psychology, but need not necessarily be the only kind of teaching that would so agree; for many diverse methods of teaching may equally well agree with psychological laws.

To know psychology, therefore, is absolutely no guarantee that we shall be good teachers. To advance to that result, we must have an additional endowment altogether, a happy tact and ingenuity to tell us what definite things to say and do when the pupil is before us. That ingenuity in meeting and pursuing the pupil, that tact for the concrete situation, though they are the alpha and omega of the teacher’s art, are things to which psychology cannot help us in the least.

Cinsiyet ve üreme, canlı yaşamının sürekliliğini sağlar. İnsanlarda cinsellik doğumla başlar ve tüm yaşam boyunca devam eder. Cinsel kimlik, kişinin biyolojik cinsiyetinden farklı olarak kendisini kadın ya da erkek olarak algılamasıdır. Sağlıklı bir cinsel kimlik gelişiminde cinsel kimlik, kişinin cinsiyetinden haberdar olması, cinsiyetine uygun davranışlar göstermesi ve bundan mutluluk duyması önemlidir.

Cinsel eğitim bireyin fiziksel, duygusal ve cinsel gelişimini anlaması olumlu bir kişilik kavramı geliştirmesi, insan cinselliğine, başkalarının haklarına, görüş ve davranışlarına saygılı bir bakış açısı edinmesi ve olumlu davranış biçimi, değer yargıları geliştirmesi eğitimidir.

Cinsel eğitimde öncelikle anne babaların eğitimi hedeflenmelidir. Aksi takdirde anne babaların istemediği takdirde çocuklar ya da ergenler istemediği kişilerden bilgi edinebilir, gözetleme, takip etme yoluna başvurabilirler, yaşıtlarından bilgi alabilirler, kendi başlarına deneyler yapabilirler. Ailede başlayan cinsel eğitim okulda da sistemli bir şekilde sürmelidir.

Ülkemiz gibi cinsel eğitim konusuna tedirgin, çekingen, korkak yaklaşılan, ayıp günah sayılan ülkelerde bu sorumluluk daha da artmaktadır. Sorumluluğun kapsamında sadece çocuklar gençler değil her yaştan her sosyo-ekonomik ve sosyo-kültürel düzeyden insanların olması gerekmektedir. Bu kitabın anne babalara öğretmenlere öğretmen adaylarına ve konuyla ilgilenen herkese yararlı olması dilerim.

Although the month is March and not November, it is never unseasonable to count up the blessings for which it is well to be thankful. In fact, from the standpoint of education, the spring is perhaps the appropriate time to perform this very pleasant function. As if still further to emphasize the fact that education, like civilization, is an artificial thing, we have reversed the operations of Mother Nature: we sow our seed in the fall and cultivate our crops during the winter and reap our harvests in the spring. I may be pardoned, therefore, for making the theme of my discussion a brief review of the elements of growth and victory for which the educator of to-day may justly be grateful, with, perhaps, a few suggestions of what the next few years may reasonably be expected to bring forth.

And this course is all the more necessary because, I believe, the teaching profession is unduly prone to pessimism. One might think at first glance that the contrary would be true. We are surrounded on every side by youth. Youth is the material with which we constantly deal. Youth is buoyant, hopeful, exuberant; and yet, with this material constantly surrounding us, we frequently find the task wearisome and apparently hopeless. The reason is not far to seek. Youth is not only buoyant, it is unsophisticated, it is inexperienced, in many important particulars it is crude. Some of its tastes must necessarily, in our judgment, hark back to the primitive, to the barbaric. Ours is continually the task to civilize, to sophisticate, to refine this raw material. But, unfortunately for us, the effort that we put forth does not always bring results that we can see and weigh and measure. The hopefulness of our material is overshadowed not infrequently by its crudeness. We take each generation as it comes to us. We strive to lift it to the plane that civilized society has reached. We do our best and pass it on, mindful of the many inadequacies, perhaps of the many failures, in our work. We turn to the new generation that takes its place. We hope for better materials, but we find no improvement.
