A shift from “full-frontal teaching” to “guide on the side” becomes easier as the amount and use of computer and Internet technologies increases. If a school (or better yet, a classroom) has numerous computers with full Internet access, then students’ can in principle direct their own learning more independently than if computers are scarce commodities. With ample technology available, teachers can focus much more on helping individuals in developing and carrying out learning plans, as well as on assisting individuals with special learning problems. In these ways a strong shift to computers and the Internet can change a teacher’s role significantly, and make the teacher more effective.

But technology also brings some challenges, or even creates problems. It costs money to equip classrooms and schools fully: often that money is scarce, and may therefore mean depriving students of other valuable resources, like additional staff or additional books and supplies. Other challenges are less tangible. In using the Internet, for example, students need help in sorting out trustworthy information or websites from the “fluff”, websites that are unreliable or even damaging (Seiter, 2005). Providing this help can sometimes be challenging even for experienced teachers. And some educational activities simply do not lend themselves to computerized learning—sports, for example, driver education, or choral practice. As a new teacher, therefore, you will need not only to assess what technologies are possible in your particular classroom, but also what will actually be assisted by new technologies. Then be prepared for your decisions to affect how you teach—the ways you work with students.

New trend #3: accountability in education

In recent years, the public and its leaders have increasingly expected teachers and students to be accountable for their work, meaning that schools and teachers are held responsible for implementing particular curricula and goals, and that students are held responsible for learning particular knowledge. The trend toward accountability has increased the legal requirements for becoming and (sometimes) remaining certified as a teacher. In the United States in particular, preservice teachers need more subject-area and education-related courses than in the past. They must also spend more time practice teaching than in the past, and they must pass one or more examinations of knowledge of subject matter and teaching strategies. The specifics of these requirements vary among regions, but the general trend—toward more numerous and “higher” levels of requirements—has occurred broadly throughout the English-speaking world. The changes obviously affect individuals’ experiences of becoming a teacher—especially the speed and cost of doing so.

Public accountability has led to increased use of high-stakes testing , which are tests taken by all students in a district or region that have important consequences for students' further education (Fuhrman&Elmore, 2004). High-stakes tests may influence grades that students receive in courses or determine whether students graduate or continue to the next level of schooling. The tests are often a mixture of essay and structured-response questions (such as multiple-choice items), and raise important issues about what teachers should teach, as well as how (and whether) teachers should help students to pass the examinations. It also raises issues about whether high-stakes testing is fair to all students and consistent with other ideals of public education, such as giving students the best possible start in life instead of disqualifying them from educational opportunities. Furthermore, since the results of high-stakes tests are sometimes also used to evaluate the performance of teachers, schools, or school districts, insuring students’ success on them becomes an obvious concern for teachers—one that affects instructional decisions on a daily basis. For this reason we discuss the purpose, nature, and effects of high-stakes tests in detail in [link] .
