To a large extent, professional development in education is still thought of in terms of inservice training for practicing educators. If the objective is systemic reform of the entire educational system, then distinctions between preservice training and inservice training are artificial. Judge (1988) contends that teacher education and the configuration of teachers careers and responsibilities are the two major determinants of the professional culture of schools. Professional development should focus on the career-long professional learning of all educators (including university faculty), which requires much greater coherence between preservice and inservice training, as well as substantial changes in the structure of schooling to make continuous learning an integral part of every educators world of work.
Research on professional development in the last decade has greatly enhanced our understanding of effective practices. Learning theorists have demonstrated that people learn best through active involvement and by thinking about and articulating what they have learned (Resnick, 1989; Vygotsky, 1978). The wide array of learning opportunities that are advocated for students -- learning activities that engage students in experiencing, creating, and working with others on solving real problems -- are rarely the kinds of rich learning experiences available to teachers (Lieberman, 1995). The old "training model" for teachers development of short-term workshops with little follow-up is still the dominant mode (Little, 1993; McLaughlin, 1991; Miller & Lord, 1994). Historically the old training model has been ineffective because it lacks focus, intensity, follow-up, and coherence with district goals for student performance (Corcoran, 1995; Joyce & Showers, 1988). The inadequacy of the old model is even more apparent today with the ambitious visions of schooling in current reform initiatives. Darling-Hammond and McLaughlin (1995) capture the scope of the challenge confronting educators today:
The vision of practice that underlies the nations reform agenda requires most teachers to rethink their own practice, to construct new classroom roles and expectations for student outcomes, and to teach in ways they have never taught before -- and probably never experienced as students. The success of this agenda ultimately turns on teachers success in accomplishing the serious and difficult tasks of learning the skills and perspectives assumed by new visions of practice and unlearning the practices and beliefs about students and instruction that have dominated their professional lives to date. (Darling-Hammond & McLaughlin, 1995, p. 597, emphasis in original.)
Growing understanding of the learning process, especially adult learning, has produced a substantial consensus about the critical attributes that constitute effective professional development practices. A synthesis of several recommended guidelines produced the following list of essential characteristics:
These attributes represent a significant paradigm shift for professional development, one that has growing recognition but is not yet common practice. A few new models for effective professional development have emerged in recent years that incorporate many of these essential characteristics. They respect the expertise of accomplished teachers and build teacher development activities around notions of colleagueship and disciplined inquiry in the context of professional learning communities.
These networks provide "critical friends" to examine and reflect on teaching, and provide opportunities to share experiences about teachers efforts to develop new practices. McLaughlins (1994) research on professional learning in secondary schools found that teachers who report a high sense of efficacy, who feel successful with todays students, also share one characteristic: membership in some kind of strong professional community. These teachers singled out their professional discourse community as the reason that they have been successful in adapting to todays students, the source of their professional motivation and support, and the reason they did not burn out in the face of exceedingly demanding teaching situations.
Meaningful leadership opportunities have also emerged as teachers assume the roles of mentors, university adjuncts, researchers, and teacher leaders within various restructuring efforts and professional organizations.
Three organizations are leading the effort to professionalize teaching by strengthening its quality-assurance mechanisms (Wise & Leibrand, 1993). They are the National Council for Accreditation of Teacher Education (NCATE); the Council of Chief State School Officers (CCSSO), through its task force on licensing standards, the Interstate New Teachers Assessment and Support Consortium (INTASC); and the National Board for Professional Teaching Standards, which is developing advanced standards for teacher performance. Three policy mechanisms being pursued in concert are accreditation, licensing, and advanced certification. The CCSSO has developed a flowchart that begins with the adoption of standards and leads to assessment in three areas: (1) preparation, (2) induction/support, and (3) professional development. Acknowledging induction as a phase of teacher preparation demonstrates a recognition that all beginning teachers need support and that teacher preparation is ongoing and must be connected to practice. The impact of these standards will depend on how states implement them.
The National Board for Professional Teaching Standards has worked with teachers and national teacher organizations to develop standards and assessment procedures for recognition of exemplary teachers. Hopefully this voluntary certification will reward master teachers for their expertise and help promote these teachers to positions of greater responsibility. Teachers who have engaged in this intense teacher assessment process claim that they learned more by going through the process than by partaking in any other professional development activity in their entire career, because it requires them to document their practice and reflect on their strengths and weaknesses (Bradley, 1994).
School-university partnerships such as professional development schools provide new models for the teacher education continuum, serving as exemplars of practice and builders of knowledge. School-university collaborations include work in curriculum development, change efforts, and research. Darling-Hammond and McLaughlin (1995) note that when such relationships emerge as true partnerships, they can create new and more powerful kinds of knowledge about teaching and schooling. The integration of theory and practice has the potential to produce more practical, contextualized theory and more theoretically grounded, broadly informed practice. The importance of reciprocal learning within such arrangements is not always recognized by university teacher educators. The public schools provide critical learning opportunities for university faculty to become reacquainted with, and develop a deeper understanding of, the realities of contemporary classrooms.
The accumulative lessons learned about effective professional development strategies indicate that organizational structures need to be flexible and dynamic, responding to the changing needs of teachers and the profession. Professional development opportunities must be able to start where educators are now and build on their knowledge and skills. There is no one-size-fits-all approach that will meet the needs.
Networks, coalitions, and partnerships provide opportunities for educators to commit themselves to topics that are of intrinsic interest to them or that develop out of their work (Lieberman, 1995). Partnership arrangements also provide an opportunity for cross-role participation that stimulates shared understandings and capitalizes on the combined expertise of teachers, principals, counselors, and university faculty, as well as provide essential professional socialization for preservice teachers as they enter the profession.
Darling-Hammond and McLaughlin (1995) recommend that policymakers focus on the richness and overall "menu" of opportunities for professional learning. What is needed is an extensive infrastructure of professional development opportunities that provides multiple and ongoing occasions for critical reflection and that involves educators in designing coherent learning experiences.
