The other end of the age spectrum has also expanded. Many individuals take courses well into adulthood even if they do not attend formal university or college. Adult education , as it is sometimes called, often takes place in workplaces, but it often also happens in public high schools or at local community colleges or universities. Some adult students may be completing high school credentials that they missed earlier in their lives, but often the students have other purposes that are even more focused, such as learning a trade-related skill. The teachers of adult students have to adjust their instructional strategies and relationships with students so as to challenge and respect their special strengths and constraints as adults (Bash, 2005). The students’ maturity often means that they have had life experiences that enhance and motivate their learning. But it may also mean that they have significant personal responsibilities—such as parenting or a full-time job—which compete for study time, and that make them impatient with teaching that is irrelevant to their personal goals or needs. These advantages and constraints also occur to a lesser extent among “regular” high school students. Even secondary school teachers must ask, how they can make sure that instruction does not waste students’ time, and how they can make it truly efficient, effective, and valuable. Elsewhere in this book (especially in [link] , [link] , and [link] , about assessment and instruction), we discuss these questions from a number of perspectives.

New trend #2: using technology to support learning

For most teachers, “technology” means using computers and the Internet as resources for teaching and learning. These tools have greatly increased the amount and range of information available to students, even if their benefits have sometimes been exaggerated in media reports (Cuban, 2001). With the Internet, it is now relatively easy to access up-to-date information on practically any subject imaginable, often with pictures, video clips, and audio to accompany them. It would seem not only that the Internet and its associated technologies have the potential to transform traditional school-based learning, but also that they have in fact begun to do so.

For a variety of reasons, however, technology has not always been integrated into teachers’ practices very thoroughly (Haertel&Means, 2003). One reason is practical: in many societies and regions, classrooms contain only one or two computers at most, and many schools have at best only limited access to the Internet. Waiting for a turn on the computer or arranging to visit a computer lab or school library limits how much students use the Internet, no matter how valuable the Internet may be. In such cases, furthermore, computers tend to function in relatively traditional ways that do not take full advantage of the Internet: as a word processor (a “fancy typewriter”), for example, or as a reference book similar to an encyclopedia.

Even so, single-computer classrooms create new possibilities and challenges for teachers. A single computer can be used, for example, to present upcoming assignments or supplementary material to students, either one at a time or small groups. In functioning in this way, the computer gives students more flexibility about when to finish old tasks or to begin new ones. A single computer can also enrich the learning of individual students with special interests or motivation. And it can provide additional review to students who need extra help. These changes are not dramatic, but they lead to important revisions in teachers’ roles: they move teachers away from simply delivering information to students, and toward facilitating students’ own constructions of knowledge.
