Learning means knowing and mastering a subject. For many people, thrust suddenly into a new classroom and asked sud denly to teach a new subject, this may seem an impossible luxury.Yet a teacher must seek to have full command of a subject, not just enough knowledge to get by or to know more than the very best students. A teacher should possess enough knowledge of a subject to be able to consider it independently, to play confidently with it, to entertain surmises about it, to imagine its possible significances and implications when it is placed in various contexts. A teacher, that is, should know enough to be a thinker as well as an instructor. When that is the case, the teacher has joined a discipline, a professional guild of people with an agreed-upon warrant to consider themselves guardians of, and contributors to, a branch of knowledge.
Learning embodies the act of learning. In many respects, the search for knowledge is infectious; it can be transmitted to others, and it can be caught. Possibly the best way for teachers to transmit learning is to embody the act of doing so-to be seen among papers and books ("these kinsmen of the shelf," as Emily Dickinson called them), scurrying toward a library, exclaiming upon the solution to a problem, expressing delight when a student proposes a plausible interpretation new to the teacher. Teachers, in showing their students how to learn, must seek to be caught jagrante delicto with their subject, for the aspiration to learn should be as compelling to students as the knowledge they gain. It is a teacher's
infectious enthusiasm for learning itself, as much as the student's own curiosity about the teacher's subject, that is apt to captivate a student.
Veteran teachers, long familiar with the material they teach, may choose to stop learning because it seems no longer justified. This is always a mistake, if only because it risks suggesting an unbridgeable distance between the teacher, who seems to know it all, and the students, who may think they know nothing-which is also wrong. Thus for a teacher to stop learning is to destroy one of the principal means a teacher has to bridge the gap between ignorance and knowledge and between despair and hope. What is more,
to stop learning suggests to students that a teacher is bored with the subject; and, alas, boredom is every bit as infectious as enthusiasm.
1.Learning requires keeping up with one's subject. This may be a teacher's hardest task, for it requires application after the normal, depleting workday is done. Yet it must be undertaken. If a teacher falls behind in a subject, so do the students, whose preparation for advancement in competition with others is thereby diminished. Keeping current with a body of knowledge does not, however, necessitate only solitary reading and study; it can be accomplished with colleagues in study groups, in formal programs of continuing professional education, and by attendance at meetings of scholars and fellow professionals.
2.What matters is not the means of staying abreast of knowledge but the actual pursuit of that knowledge.
1.Learning conveys the spirit and love of learning to others. All teachers are in effect missionaries for their subjects.
2.They must care passionately about what they teach; they must be able to reveal to their students how exciting learning can be. That is an additional reason why teachers must clearly possess knowledge, or at least display a visible desire to possess it; only then can their love of knowledge be exemplified in their enthusiasm and bearing, in the sheer fun of engaging in discussion, hunting down a fact, polishing a skill, exploring a new subject, reading a book for the first time.
3.Of course, trying to transmit knowledge has its risks, the chief being that students often do not want to learn- or at least to learn what they are asked to learn at the time in their lives when they are asked to learn it. A pertinent story is told of John Scotus Erigena, an Irish teacher and philosopher in the court of the Holy Roman Emperor in northem France. Our philosopher was murdered by a group of his students who hacked him to death with their pens because, it is said, he tried to force them to think.
One moral of this tale, among others, is that not all subjects, after all, captivate students as naturally as, say, learning to drive attracts the interest of teenagers.
The culture has already done a reasonably good job of explaining to the young the advantages of driving a car. But when it comes to such subjects as foreign languages or the physical sciences, teachers have more work cut out for them; it is they, and few others, who can best reveal how and why subjects scarcely known to their students offer excitement, satisfaction, and utility. And to do that, teachers must know their subjects thoroughly and assume the responsibility and risk of finding ways to impart those subjects to their often recalcitrant students.
Learning means being open to the knowledge of others, especially of one's own students. Often, because teachers must learn from other authorities in a field, they forget that their students may be authorities too, that they may surpass their teachers in love for a subject, or knowledge of it, or skill and intelligence. After all, is it not all teachers' best dream that their students become so fueled by their teachers' knowledge as to surpass it? Thus teachers must signal to their students that the search for knowledge is cooperative and collective, that its pursuit is a shared journey-though one that often requires much solitary work.
Detecting ignorance while inadvertently overlooking understanding is one of the great hazards of all teaching. That is why teachers must work hard to encourage their students to make known their knowledge to other students; that is why they must provide the settings, free from constraint and evaluation, in which students can do so. In this way, teachers themselves are helped to focus on what students know rather than on what they do not.
Learning provides the basis for independent thought. Active engagement in a field of knowledge becomes critical at that stage when teachers realize that their engagement arises from the possession of enough knowledge to be confident in thinking about the field independently. Recognition of oneself as a thinker as well as a teacher-as someone who is part of a larger community of learning, as capable as anyone else of engaging in the intellectual play of knowledge - may be among the most difficult transitions in a teacher's professional life. Yet when that transition occurs, a new world opens, new authority is gained, and a new teacher is born-one who determines independently what is best for students and what they should know. At this stage, too, the teacher recognizes that learning is an end in itself, that not everything needs to be related to instruction, that thinking is a world without end, without known outcome.
Learning justifies learning.
1.A teacher's confidence in the intrinsic worth of knowledge is fundamental to all instruction. Such deep-rooted belief makes a teacher able to relate knowledge to life, to all human experience. To students' typical questions, "Why do we have to learn this? What good is such knowledge?" the typical instrumental answers come to mind easily: "Because it's required by the school board." "Because you will do better on your licensing exam." "Because you'll need it later when you study economics." But the teacher with deep learning answers with conviction and authority more pertinently: "Because acquiring this knowledge is difficult.
2.Because you will feel triumphant when it no longer confuses you. Because you will enjoy what you can do with it. Because in learning it you may discover new perspectives on life, new ways of thinking. Because its possession will make you more alive than its alternative, which is ignorance."
1.The teachers whom we remember most vividly are those who knew their subjects best and transmitted them with the greatest intensity and love.
2.They were confident in their knowledge, and not dogmatic; they acted out their own struggles to understand in front of us, joyful when they understood something fresh, troubled when they did not or could not know. They joined us at the laboratory bench, in the library, at the museum, puzzling with us over a test tube result, complaining about a book's interpretation, discovering a painting's meaning. They stood before us to present the act of learning with a sort of honesty that we rarely encounter in everyday life. It is such examples of passion and exhilaration that students need in their teachers. Only in that way can students meet the importunate demands of learning with a full heart; only then can the thirst for learning move them on.
