21st-Century Teacher Education

For almost as long as there have been institutions dedicated to the preparation of new teachers, the endeavor has come in for criticism. Teacher education has long struggled both to professionalize and to fully integrate itself into mainstream academia. At the core of this struggle was a perception that there was no body of specialized knowledge for teaching that justified specialized training.
education’s refusal to train teachers to use scientifically based reading methods, Reid Lyon, who headed a 30-year study at the National Institutes of Health of how people best learn to read, once stated, “If there was any piece of legislation that I could pass it would be to blow up colleges of education.” The suggestion was repeated in a 2009 speech by Craig Barrett, the former chair of Intel Corporation, who had been working to improve math and science education. Arne Duncan, the Obama administration’s secretary of education, having previously served as schools superintendent in Chicago, one of the nation’s most troubled school districts, gave back-to-back speeches early in his tenure decrying the state of the field: “By almost any standard, many if not most of the nation’s 1,450 schools, colleges, and departments of education are doing a mediocre job of preparing teachers for the realities of the 21st-century classroom,” and “America’s university-based teacher preparation programs need revolutionary change, not evolutionary thinking.”
An occasional insider has joined the fray. Arthur Levine, former dean of what many consider to be the preeminent teacher-preparation program, Teachers College, Columbia University, has been savage in his criticism: “Teacher education is the Dodge City of the education world. Like the fabled Wild West town, it is unruly and disordered,” he wrote in 2006. He then swiftly abandoned his involvement with traditional teacher preparation altogether, starting up his own alternative pathway to teaching, the Woodrow Wilson fellowships. At the time, his remarks were viewed as mutinous by many of his colleagues, particularly his view that the primary accrediting body for teacher education, the National Council for Accreditation of Teacher Education (NCATE), ought to be scrapped. Several years later, insiders conceded that Levine had been right. Accreditation is now being revamped under a new name, the Council for the Accreditation of Educator Preparation (CAEP).

Teacher Education

The Perspective of Teacher Educators
Almost all teacher educators acknowledge that the field has deep problems, but their concern has seldom been about the issues raised by external critics such as lack of selectivity, an imbalance between content and pedagogy, or the lack of value delivered. These differences aren’t always recognized because the insider critiques often sound a lot like the external critiques. In reality, insiders are more concerned about the chaos in the field.
The core of insider complaints is not that the profession is marching in the wrong direction,  as some believe, but that too many of its foot soldiers are out of step, inadequately provisioned, and carrying the wrong weapons. This disarray is not surprising, given that the training takes place at 1,450 higher-education institutions in the United States, each of which houses anywhere from three to seven teacher-preparation programs. Fewer than half of these institutions have earned national accreditation—an anomaly not found in other professions—leaving the rest answerable to no one.
The most revealing insight into what teacher educators believe to be wrong or right about the field is a lengthy 2006 volume published by the American Educational Research Association (AERA), Studying Teacher Education. It contains contributions from 15 prominent deans and education professors and was intended to provide “balanced, thorough, and unapologetically honest descriptions of the state of research on particular topics in teacher education.” It lives up to that billing. First, the volume demonstrates the paucity of credible research that would support the current practices of traditional teacher education, across all of its many functions, including foundations courses, arts and sciences courses, field experiences, and pedagogical approaches, as well as how current practice prepares candidates to teach diverse populations and special education students. More intriguing, however, is the contributors’ examination of the dramatic evolution of the mission of teacher education over the last 50 years, in ways that have certainly been poorly understood by anyone outside the profession.
Studying Teacher Education explains the disconnect between what teacher educators believe is the right way to prepare a new teacher and the unhappy K–12 schools on the receiving end of that effort. It happens that the job of teacher educators is not to train the next generation of teachers but to preparethem.

Disadvantaged Students

Disadvantaged Students
One consistent pattern in our results is that the benefits of a school tour are generally much larger for students from less-advantaged backgrounds. Students from rural areas and high-poverty schools, as well as minority students, typically show gains that are two to three times larger than those of the total sample. Disadvantaged students assigned by lottery to receive a school tour of an art museum make exceptionally large gains in critical thinking, historical empathy, tolerance, and becoming art consumers.
It appears that the less prior exposure to culturally enriching experiences students have, the larger the benefit of receiving a school tour of a museum. We have some direct measures to support this explanation. To isolate the effect of the first time visiting the museum, we truncated our sample to include only control-group students who had never visited Crystal Bridges and treatment-group students who had visited for the first time during their tour. The effect for this first visit is roughly twice as large as that for the overall sample, just as it is for disadvantaged students.
In addition, we administered a different version of our survey to students in kindergarten through 2nd grade. Very young students are less likely to have had previous exposure to culturally enriching experiences. Very young students make exceptionally large improvements in the observed outcomes, just like disadvantaged students and first-time visitors.
When we examine effects for subgroups of advantaged students, we typically find much smaller or null effects. Students from large towns and low-poverty schools experience few significant gains from their school tour of an art museum. If schools do not provide culturally enriching experiences for these students, their families are likely to have the inclination and ability to provide those experiences on their own. But the families of disadvantaged students are less likely to substitute their own efforts when schools do not offer culturally enriching experiences. Disadvantaged students need their schools to take them on enriching field trips if they are likely to have these experiences at all.

Schools or Society
It is not clear why the academic skills of 13-year-olds at the bottom of the skills distribution have risen. It could be the result of improved schooling in Grades K–8, perhaps due to the standards-based reform efforts discussed above.
However, it could also stem from improvements in the out-of-school circumstances of American children most at risk of academic failure.
Between 1980 and 2000, the fraction of U.S. four-year-olds enrolled in classroom-based preschool programs rose from one-half to two-thirds. This trend could have resulted in more children acquiring the cognitive and socioemotional skills needed for success in school.
In addition, the birth rate among 15- to 17-year-old girls declined by 44 percent between 1990 and 2008, and by 60 percent among black teens. Because children born to teenage mothers are prone to develop problems that inhibit academic success, this trend could have contributed to both the increases in the mathematics skills of 13-year-olds and to an increase in the high school graduation rate. Moreover, the decline in the teenage birth rate could have reduced the number of girls who left school to care for children and thus resulted in higher graduation rates.
Yet another salutary trend is a 47 percent decline between 1994 and 2009 in the arrest rate of teenagers for violence-related offenses. One of several reasons this could have contributed to a rise in the high school graduation rate is that involvement with the criminal justice system typically results in a marked increase in absences from school.
Finally, it is possible that the introduction of more difficult GED examinations in 2002, which resulted in a temporary decline in the number of 16- to 18-year-olds obtaining the credential, contributed to the increase in the high school graduation rate during the decade ending in 2010. In 2002, after the GED Testing Service introduced a more difficult set of GED tests, the percentage of high school completers receiving the GED dropped from 17 to 10 percent. Since 2004, it has held steady at about 12 percent, again with about half of GEDs going to 16- to 20-year-olds.

Understanding the promise of personalized

Understanding the promise of personalized learn by sarwar khatri                          Hernandez
Personalized learning theory is built on the twin pillars of 1) differentiated learning pathways for students and 2) feedback that enables students to make informed judgments about what they’ve learned, how well they’ve learned it, and what to learn next. The importance of these two pillars for effective education is well established, yet traditional schools struggle mightily with both, mostly because there are only 24 hours in a day and educators are human.
Built on these two pillars, personalized learning has the potential to fulfill some of the most basic hopes families have for their children: “I just want my child to get what they need, when they need it.” “I want my child to grow and develop from where she is today.” “I want my child to experience success and grow in confidence as a learner.”
Differentiated learning paths honor student variation in both background knowledge and ability. Effective teachers assign work to students that is “appropriate to their current levels of competence.” But most teachers’ ability to manage multiple learning paths in multiple subjects is limited, at best. Arbitrary, age-based academic standards and fixed pacing guides only exacerbate the problem.
Substantially reorganizing school to honor the variation in student readiness is an option that educators only infrequently employ. At my children’s elementary school, the entire student body learns math at the same time, and students across the school are regrouped based on their needs, not their grade or age. I’m not arguing that this practice is the only answer to our problems, but it is clearly much easier to say “we differentiate for every child” than to actually put differentiation into practice.
Feedback has a powerful impact on student achievement, and providing it is entirely within the school’s control. In traditional classrooms, teachers are the bottleneck in giving student feedback unless there are other feedback loops students can access directly. In personalized learning environments, students theoretically have access to ample, frequent, and actionable feedback from multiple sources, including content, peers, and teachers. Teachers can focus their energies on 1) providing the feedback that only they can provide and 2) making sense of the feedback generated by other sources.
Together, differentiated learning paths and feedback create the basic conditions for personalized learning to occur. In addition, students need to own their learning. Every student should have the opportunity to go to college, where students are primarily responsible for their learning. This lies in stark contrast to K–12, where teachers are primarily responsible for student learning. Ensuring college readiness requires improving executive function and ramping up background knowledge, neither of which are core competencies in today’s schools. It is unrealistic to assume that in a traditional school, students will receive a seven-step lesson for every chunk of background knowledge they’ll need to succeed beyond the 4th grade. We need to organize our schools in such a way that students acquire background knowledge, accrue expertise, and develop independent learning skills.
Among the issues frequently raised by skeptics are that the research base for student-driven learning is abysmal. Individualized instruction has shown particularly weak effects on student achievement as have other methods that put the teacher in the role of facilitator. I suspect insufficient attention to background knowledge is the Achilles heel of those who believe teachers should be the “guide on the side.” I remain optimistic nonetheless, for two reasons. First, now that I have a deeper appreciation for what it takes to develop stable personalized-learning environments, I’m skeptical that prior efforts had the resources, capacity, or technology necessary for those initiatives to succeed. Second, the new wave of personalized learning draws on a set of instructional strategies that have shown particularly large effects on student achievement: feedback, peer tutoring, mastery learning, goal setting, and even direct instruction.
A second contention is that students are incapable of making good decisions about their learning. I agree that many students, without any structures, supports, or feedback, will make poor decisions about their education. But schools that move to student-driven environments create supports so students can function well. These include increased coaching, goal setting, feedback on progress, tiered supports, peer tutoring, small-group instruction, and other resources that together enable a greater percentage of students to manage their own learning effectively. For example, the first thing most schools do is put in a “minimum pace” to help address the “slow velocity” problem.
Opponents argue that students will avoid hard thinking in personalized environments without teachers. I generally agree that teachers are best positioned to lead cognitively challenging activities like Socratic seminars, deep reading, and math talk. Personalized learning environments are better suited to teach basic skills and background knowledge than to teach critical thinking. That said, students with significant background knowledge are capable of hard thinking when they take more ownership of their learning, and we need to honor those capabilities.
Similarly, opponents assert that personalized learning precludes great pedagogy like argument, discussion, and debateThis is a false choice. Students can engage in personalized learning for a portion of the day and spend the rest of their time in rich learning activities that only teachers can provide. The bet here is that if students can drive their development of basic skills and background knowledge, teachers can “trade up” and focus their energies on challenging tasks and compelling experiences. Teachers should be in the business of creating “aha” moments for children, not figuring out seven different math lessons for 25 different students.
Ben Riley argues that one of the important roles of the teacher is to “pick what to study next,” and Dan Willingham acknowledges that “craft knowledge trumps science” when it comes to differentiation. But clinical diagnoses have extraordinarily high error rates. In his book Thinking, Fast and Slow, Daniel Kahneman cites a study in which experienced radiologists contradicted themselves 20 percent of the time when they saw the same chest x-ray on separate occasions. A recent Johns Hopkins study found that 28 percent of ICU patients had at least one missed diagnosis when they died. It is not unreasonable to believe that error rates are higher in education because of the lack of reliable heuristics and a relatively thin research base. This is not teacher bashing. If education is anything like other professions that rely on clinical judgment, it is likely that one in four education diagnoses (probably more) is incorrect. Students are best served when they have access to both expert judgment and the types of algorithmic supports possible in personalized learning environments.
I may be overly optimistic about the promise of personalized learning, but I think critics overestimate the effectiveness of the average traditional classroom.
