问题     To improve the teaching skills, what you need will depend on what you want to do. Most teachers have computers, and most have at least some access to email and the Internet. In many schools and universities, most students do, too. Many teaching opportunities are likely to be available to you; therefore, use equipment you and your students already have. (46)Other techniques require more advanced technologies that you may or may not wish to purchase on your own, and that your institution may or may not make available to you. It should be obvious, therefore, that you should make no plans for using electronic tools before making sure that both you and your students will have access to the necessary technology.
    But owning, or having access to technology is usually only a first step. Even more important is learning how to use it. This is one of the biggest challenges facing anyone who wishes to use electronic tools, because the knowledge is not always easy to acquire. Many people, of course, are highly skilled in computer technology and know how to teach themselves to do almost anything. (47)But many other people, who have limited computer skills, are easily intimidated by new and unfamiliar tasks, and tend to avoid doing anything that requires them to learn something very different from the things to which they are accustomed. If you fall in the latter group but wish to expand your ability to use electronic tools, you need to find help.
    Some institutions offer extensive assistance through their computer centers or their information technology services. Some departments have staff members or graduate student assistants who are hired to handle computer-related problems. There are also many excellent reference works to help you learn about various electronic tools. (48)Just as you must be sure that you have the necessary technology at your disposal before you decide to use electronic tools in your teaching, so you must also make sure that you have access to the necessary help in learning to use it.
    Keep in mind, finally, that the technology associated with computers and the Internet changes with breathtaking speed. (49)Although certain skills will remain useful to you over long periods of time, there will be many things that will have to be relearned time and time again. The rapidity of change in this field can be bewildering and intimidating. But it is also the source of some valuable innovations that can be of great use to you.
    Before introducing new teaching techniques, therefore, it is wise to make a quick inventory of your own end your school’s electronic teaching resources. (50)You will not want to discover halfway through a project that there are major obstacles such as insufficient equipment, inadequate support, or inappropriate professional incentives. Answering a few simple questions can help you determine how practical and promising your planned innovations in electronic teaching are likely to be. While some answers may lie as close as your departmental colleagues, others might require conferring with departmental administrators, librarians, or computer support organizations.
