Further research is needed to examine the scope and effectiveness of the many individual programs and initiatives. (2002). Administrators who take a more flexible approach can support effective laboratory teaching by providing teachers with adequate time and space for ongoing professional development and shared lesson planning. Administrators allocate time, like other resources, as a way to support teachers in carrying out these routines. Only 11 percent of responding teachers indicated that science teachers in their school regularly observed other science teachers. Journal of the Learning Sciences, 6(2), 227-269. The following 10 roles are a sampling of the many ways teachers can contribute to their schools' success. Teachers must consider how to select curriculum that integrates laboratory experiences into the stream of instruction and how to select individual laboratory activities that will fit most appropriately into their science classes. Show this book's table of contents, where you can jump to any chapter by name. Researchers generally agree that the teachers academic preparation in science has a positive influence on students science achievement (U.S. Department of Education, 2000; National Research Council, 2001a). Smith, P.S., Banilower, E.R., McMahon, K.C., and Weiss, I.R. The authors of the review found that, when laboratory education is available, it focuses primarily on the care and use of laboratory equipment and laboratory safety. Science Teacher, September, 38-41. Review of Educational Research, 52 (2), 201-217. Arrangements must be made with Instructor to cover unavoidable absences or planned breaks. Because efforts to improve teachers ability to lead improved laboratory experiences are strongly influenced by the organization and administration of their schools, the following section addresses this larger context. At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory work, and the case for laboratory . Among teachers who acted as heads of science departments, 21 percent indicated that the lack of opportunities for teachers to share ideas was a serious problem for science instruction (Smith et al., 2002). Over the course of a years worth of pedagogical preparation and field experiences, the new teachers began to reorganize their knowledge of biology according to how they thought it should be taught. In an ideal world, administrators would provide adequate laboratory space and time to allow students to continue investigations over several weeks or months, and they would also provide time for students to work outside regular school hours. Those who understand: Knowledge growth in teaching. Driver, R. (1995). Journal of Research in Science Teaching, 29, 51-61. Linn, E.A. However, formulating such questions can be difficult (National Research Council, 2001a, 2001b). when studying aspects of biology . Many preservice teachers hold serious misconceptions about science that are similar to those held by their students (Anderson, Sheldon, and Dubay, 1990; Sanders, 1993; Songer and Mintzes, 1994; Westbrook and Marek, 1992, all cited in Windschitl, 2004).

In a case study of his experience, this professor called for reducing science teachers class loads so they have more time to reflect on and improve their own practice. surveys defined poor administrative support as including a lack of recognition and support from administration and a lack of resources and material and equipment for the classroom. These school-based teacher communities, in turn, not only supported teachers in improving their teaching practices, but also helped them create new resources, such as new curricula. In a guided-inquiry laboratory (GIL), the teacher provides the students with a question, or set of questions, and the students design an experiment to address the question(s). Hofstein, A., and Lunetta, V.N. Science Education, 77(1), 25-46. East Lansing, MI: National Center for Research in Teacher Education. The importance of pedagogical content knowledge challenges assumptions about what science teachers should know in order to help students attain the goals of laboratory experiences. Evaluating the evidence. A survey of students, teachers, and volunteers yielded positive results. The role of the laboratory in science teaching: Neglected aspects of research. Participant teachers were also interviewed. Available at: http://www.nsta.org/positionstatementandpsid=16 [accessed Oct. 2004]. Erroneous ideas about respiration: The teacher factor. Playing this critical role requires that teachers know much more than how to set up equipment, carry out procedures, and manage students physical activities.

Presentation to the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. In addition to the many programs to increase teachers knowledge and abilities discussed above, the scientific community sometimes engages scientists to work directly with students. Chapel Hill, NC: Horizon Research. Time constraints can also discourage teachers from the challenges of setting up and testing laboratory equipment and materials. All of these factors indirectly affect the academic achievement of the students. The Chemistry Department of City College (City University of New York) places undergraduate science and engineering majors in middle school classrooms to assist teachers during laboratory activities and learn classroom management from the teachers. (71) $4.50. Laboratories in science education: Understanding the history and nature of science. Culturally adaptive teaching and learning science in labs. The arts and science as preparation for teaching. In K. Howey and N. Zimpher (Eds. Other studies indicate that high-quality professional development can encourage and support science teachers in leading a full range of laboratory experiences that allow students to participate actively in formulating research questions and in designing and carrying out investigations (Windschitl, 2004). However, compared with other types of professionals, a higher proportion of teachers leave their positions each year. The final section concludes that there are many barriers to improving laboratory teaching and learning in the current school environment.

Available at: http://www7.nationalacademies.org/bose/March_29-30_2004_High_School_Labs_Meeting_Agenda.html [accessed Oct. 2005]. School administrators have a strong influence on whether high school science teachers receive the professional development opportunities needed to develop the knowledge and skills we have identified. The committee identified a limited portfolio of examples of promising approaches to professional development that may support teachers in leading laboratory experiences designed with clear learning outcomes in mind, thoughtfully sequenced into the flow of classroom science instruction, integrating the learning of science content and process, and incorporating ongoing student reflection and discussion. Institute participants also asked for more discussion of assessment methods for laboratory teaching, including the role of video testing, and also recommended inclusion of sessions that address teaching science laboratory classes on a small budget. Teaching for understanding was defined as including a focus on student thinking, attention to powerful scientific ideas, and the development of equitable classroom learning communities. Professional Development Partnerships with the Scientific Community. Washington, DC: Author. McDiarmid, G.S., Ball, D.L., and Anderson, C.W. (2001).

Designing professional development for teachers of science and mathematics. A cross-age study of student understanding of the concept of homeostasis. As already known, most of the teacher candidates carry out closeended laboratory - practices throughout their university education [14]. What does research tell us about learning in high school science labs? Washington, DC: Author. Laboratory training is also frequently used to develop skills necessary for more advanced study or research. In reviewing the state of biology education in 1990, an NRC committee concluded that few teachers had the knowledge or skill to lead effective laboratory experiences and recommended that "major new programs should be developed for providing in-service education on laboratory activities" (National Research Council, 1990, p. 34). Paper prepared for the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. Typically, states require only that teachers obtain post-baccalaureate credits within a certain period of time after being hired and then earn additional credits every few years thereafter. What can they contribute to science learning? The role of the laboratory in science teaching: Neglected aspects of research. Professional development opportunities for science teachers are limited in quality, availability, and scope and place little emphasis on laboratory instruction. Guiding students through the complexity and ambiguity of empirical. on specific instructional practices increased teachers use of these practices in the classroom. Educating teachers of science, mathematics, and technology.
