Google Scholar We then go on to describe approaches to supporting teachers and improving their capacity to lead laboratory experiences through improvements in professional development and use of time. Properly designed laboratory investigations should: have a definite purpose that is communicated clearly to students; focus on the processes of science as a way to convey content; incorporate ongoing student reflection and discussion; and enable students to develop safe and conscientious lab habits and procedures (NRC 2006, p. 101-102). fessional development aligned with the curricula leads to increases in students progress toward the goals of laboratory experiences (Slotta, 2004). Using questioning to assess and foster student thinking. Improving science teachers conceptions of nature of science: A critical review of the literature. All of these factors indirectly affect the academic achievement of the students. In J.M. Smith, P.S., Banilower, E.R., McMahon, K.C., and Weiss, I.R. (2002). Because many current science teachers have demographic backgrounds different from their students (Lee, 2002; Lynch, Kuipers, Pyke, and Szeze, in press), the ability to communicate across barriers of language and culture is. The program was designed in part to address weakness in science teachers understanding of the nature of science, which was documented in earlier research (Khalic and Lederman, 2000; Schwartz and Lederman, 2002). Discovery learning and discovery teaching. Looking inside the classroom: A study of K-12 mathematics and science education in the United States. Washington, DC: National Academy Press. Rather, learning is an active process which goes on within the students by guiding the learning . We do not yet know how best to develop the knowledge and skills that teachers require to lead laboratory experiences that help students master science subject matter, develop scientific reasoning skills, and attain the other goals of laboratory education. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. Smith, S. (2004). Science Education, 77(1), 25-46. What types of knowledge do teachers use to engage learners in doing science? These workshops include microteaching (peer presentation) sessions. In D.G. DeSimone, L.M., Porter, A.S., Garet, M.S., Yoon, K.S., and Birman, B. New York: Teachers College Press. 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). Goldhaber, D.D., and Brewer, D.J. Hegarty-Hazel, E. (1990). They also face uncertainty about how many variables students should struggle with and how much to narrow the context and procedures of the investigation. They appeared to have little understanding of the field writ large. Journal of Research in Science Teaching, 20, 745-754. Williams, M., Linn, M.C., Ammon, P., and Gearhart, M. (2004). Seattle: Author. (2004). The role of practical work in the teaching and learning of science. (1991). Quantitative approach was used to investigate effects of teaching science subjects in absence of science laboratory and to. Among these factors, curriculum has a strong influence on teaching strategies (Weiss, Pasley, Smith, Banilower, and Heck, 2003). Promoting inquiry-based instructional practice: The longitudinal impact of professional development in the context of systemic reform. The Fermi National Accelerator Laboratory has provided professional development programs for science teachers for several years (Javonovic and King, 1998). These findings confirm those from a substantial literature on arts and sciences teaching in colleges and universities, which has clearly documented that both elementary and secondary teachers lack a deep and connected conceptual understanding of the subject matter they are expected to teach (Kennedy, Ball, McDiarmid, and Schmidt, 1991; McDiarmid, 1994). A study of Ohios Statewide Systemic Initiative in science and mathematics also confirmed that sustained professional development, over many hours, is required to change laboratory teaching practices (Supovitz, Mayer, and Kahle, 2000, cited in Windschitl, 2004, p. 20): A highly intensive (160 hours) inquiry-based professional development effort changed teachers attitudes towards reform, their preparation to use reform-based practices, and their use of inquiry-based teaching practices. AAPT guidelines for high school physics programs. 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. 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. It appears that the uneven quality of current high school laboratory experiences is due in part to the preparation of science teachers to lead these experiences. Switch between the Original Pages, where you can read the report as it appeared in print, and Text Pages for the web version, where you can highlight and search the text. One study indicated that significant change in teaching practice required about 80 hours of professional development (Supovitz and Turner, 2000). Arlington, VA: National Science Foundation. The main purpose of laboratory work in science education is to provide students with conceptual and theoretical knowledge to help them learn scientific concepts, and through scientific methods, to understand the nature of science. Gamoran, A., Anderson, C.W., Quiroz, P.A., Seceda, W.G., Williams, T., and Ashmann, S. (2003). Studies focusing specifically on science teacher quality and student achievement are somewhat more conclusive. 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. Washington, DC: Author. Respecting childrens own ideas. The main role of a teaching assistant is to provide support to the course instructor to ensure the effective delivery of the required materials and to foster a positive learning environment. Guiding students through the complexity and ambiguity of empirical. Mortimer, E., and Scott, P. (2003). Wright, S.P., Horn, S., and Sanders, W. (1997). For example, the teacher might use descriptive or qualitative language or images to convey concepts related to. laboratory notebooks, essays, and portfolios (Hein and Price, 1994; Gitomer and Duschl, 1998; Harlen, 2000, 2001). Priestley, W., Priestley, H., and Schmuckler, J. Currently, few teachers lead this type of sense-making discussion (Smith, Banilower, McMahon, and Weiss, 2002). Science Teacher (October), 40-43. To date, over 400 RE-SEED volunteers have worked with schools in 10 states. Lee and Fradd (1998) and others observe that some scientific values and attitudes are found in most cultures (e.g., wonder, interest, diligence, persistence, imagination, respect toward nature); others are more characteristic of Western science. Available at: http://www7.nationalacademies.org/bose/July_12-13_2004_High_School_Labs_Meeting_Agenda.html [accessed May 2005]. The group employs a variety of long-term strategies, such as engaging teachers in curriculum development and adaptation, action research, and providing on-site support by lead teachers (Linn, 1997; Lederman, 2004). While teachers play an active role in lecture-based teaching methods, the students' role is usually reduced to sitting at their desks and listening passively to their teachers, to all. The limited evidence available indicates that some undergraduate science programs do not help future teachers develop full mastery of science subject matter. Teachers help their colleagues by sharing instructional resources. Haase, B.S. Final report on the evaluation of the National Science Foundations Instructional Materials Development Program.

There are promising examples of teacher professional development focused on laboratory experiences. East Lansing, MI: National Center for Research in Teacher Education. In this program, faculty modeled lower-level inquiry-oriented instruction focused on short laboratory sessions with limited lecturing and no definitions of terms. Methods of assessing student learning in laboratory activities include systematically observing and evaluating students performance in specific laboratory tasks and longer term laboratory investigations. Teachers who had engaged in even more intensive professional development, lasting at least 160 hours, were most likely to employ several teaching strategies aligned with the design principles for effective laboratory experiences identified in the research. (2004). They further report (Lederman, 2004, p. 8): By observing practicing scientists and writing up their reflections, teachers gained insight into what scientists do in various research areas, such as crystallization, vascular tissue engineering, thermal processing of materials, nutrition, biochemistry, molecular biology, microbiology, protein purification and genetics. Responsibilities of Teachers Clinical Supervision of Medical Students Resident, Fellow and Graduate Teaching Assistant as Teacher Policy Responsibilities of Learners Course Directors' Expectations of Students The teacher-learner relationship confers rights and responsibilities on both parties. 4.8. 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. These professionals use specialized instrumentation and techniques to analyze patients' samples, such as blood, urine, body fluids and tissue, and stool. You choose your level of involvement based on your needs. These studies confirm earlier research findings that even the best science curriculum cannot teach itself and that the teachers role is central in helping students build understanding from laboratory experiences and other science learning activities (Driver, 1995). 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).
