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. Undergraduate science students, including preservice teachers, engage. van Zee, E., and Minstrell, J. U.S. Department of Education. Journal of Science Teacher Education, 6(2), 120-124. Earn CE Get Involved Advocate/Support Your Profession London, England: Kluwer Academic. Deng (2001) describes pedagogical content knowledge for science teachers as an understanding of key scientific concepts that is somewhat different from that of a scientist. Baumgartner, E. (2004).

A new wave of evidenceThe impact of school, family, and community connections in student achievement. A Japanese high school language lab shows students' positions (2004). Project ICAN includes an intensive three-day summer orientation for science teachers followed by full-day monthly workshops from September through June, focusing on the nature of science and scientific inquiry. As teachers move beyond laboratory experiences focusing on tools, procedures, and observations to those that engage students in posing a research question or in building and revising models to explain their observations, they require still deeper levels of science content knowledge (Windschitl, 2004; Catley, 2004). For example, in developing the Computers as Learning Partners science curriculum unit, Linn and colleagues researched how well models of thermodynamics at various levels of abstraction supported students learning. Teachers also need to know how to judge the quality of students oral presentations. National Science Teachers Association. Smith, P.S., Banilower, E.R., McMahon, K.C., and Weiss, I.R. 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. Their previous, closely prescribed laboratory experiences had not helped them to understand that there are many different ways to effect a particular chemical transformation. In these discussions, the teacher helps students to resolve dissonances between the way they initially understood a phenomenon and the new evidence. Rethinking laboratories. ), Knowledge base for the beginning teacher. (1990). The teachers participated in and analyzed practical laboratory activities, studied theoretical underpinnings of the science education they were receiving, and learned about safety issues during hands-on activity. The paraprofessional would help with setup, cleanup, community contacts, searching for resources, and other types of support (National Science Teachers Association, 1990). ), International handbook of science education (pp. Lee, O., and Fradd, S.H. 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. Emerging issues and practices in science assessment. Further research is needed to examine the scope and effectiveness of the many individual programs and initiatives. He suggests that a high school physics teacher should know concepts or principles to emphasize when introducing high school students to a particular topic (p. 264). Teachers, Laboratory Attendants and Gardeners must be made to attend, at regular . Clearly, their preservice experiences do not provide the skills and knowledge needed to select and effectively carry out laboratory experiences that are appropriate for reaching specific science learning goals for a given group of students. Washington, DC: Brookings Institution. when studying aspects of biology . Coffey, Everyday assessment in the science classroom (pp. Journal of Research in Science Teaching, 31, 621-637. And, among teachers who left because of job dissatisfaction, mathematics and science teachers reported more frequently than other teachers that they left because of poor administrative support (Ingersoll, 2003, p. 7). Designing professional development for teachers of science and mathematics. Generally, the body of research is weak, and the effects of teacher quality on student outcomes are small and specific to certain contexts. Similarly, Hilosky, Sutman, and Schmuckler (1998) observe that prospective science teachers laboratory experiences provide procedural knowledge but few opportunities to integrate science investigations with learning about the context of scientific models and theories. Teachers College Record, 105(3), 465-489. Sign up for email notifications and we'll let you know about new publications in your areas of interest when they're released. McComs (Eds. Equity for linguistically and culturally diverse students in science education. Laboratories in science education: Understanding the history and nature of science. The guidelines note that simply maintaining the laboratory requires at least one class period per day, and, if schools will not provide teachers with that time, they suggest that those schools either employ laboratory technicians or obtain student help. (Working paper prepared in collaboration with the National Conference of State Legislatures.) (2004). We then compare the desired skills and knowledge with information about the current skills and knowledge of high school science teachers. Boys and girls in the performance-based classroom: Whos doing the performing? Engaging students in analysis of data gathered in the laboratory and in developing and revising explanatory models for those data requires teachers to be familiar with students practical equipment skills and science content knowledge and be able to engage in sophisticated scientific reasoning themselves. Available at: http://www.nsta.org/positionstatementandpsid=16 [accessed Oct. 2004]. In addition, few high school teachers have access to curricula that integrate laboratory experiences into the stream of instruction. (1996). Discovery learning and discovery teaching. Fraser and K.G. This paper explores the role of laboratory and field-based research experiences in secondary science education by summarizing research documenting how such activities promote science learning. Teacher and classroom context effects on student achievement: Implications for teacher evaluation. One study indicated that significant change in teaching practice required about 80 hours of professional development (Supovitz and Turner, 2000). Qualifications of the public school teacher workforce: Prevalence of out-of-field teaching 1987-88 to 1999-2000. McComas, W.F., and Colburn, A.I.

This body of knowledge addressed the kind of laboratory instruction given to students, consideration of students with special needs, supportive teaching behaviors, models to engage students working in small groups, the sequencing of instruction, and modes of assessment (p. 121). Science Education, 77(3), 301-317. Supovitz, J.A., Mayer, D.P., and Kahle, J. 357-382). University of Michigan Physics Department: GSI training course. ASCP understands your role in the medical laboratory and has developed cost effective learning products, tools to manage your re-certification, and opportunities for you to grow as a leader in the laboratory. The final section concludes that there are many barriers to improving laboratory teaching and learning in the current school environment. You will need to develop your own teaching style, your own way of interacting with students, and your own set of actions that determine the learning atmosphere of the classroom. Zip. In this approach classes meet every other day for longer blocks of about 90-100 minutes, instead of every day for 40 or 45 minutes. Prospective and practicing secondary school science teachers knowledge and beliefs about the philosophy of science. Educational Evaluation and Policy Analysis, 23(1), 57-77. (2001). A professor engaged upper level chemistry majors in trying to create a foolproof laboratory activity to illustrate the chemistry of amines for introductory students. Harrison and Killion (2007) defined the roles of . The teachers skills in posing questions and leading discussions also help students to effectively and accurately communicate their laboratory activities and the science sense they make from them, using appropriate language, scientific knowledge, mathematics, and other intellectual modes of communication associated with a particular science discipline. In the ICAN program, teachers participate in science internships with working scientists as one element in a larger program of instruction that includes an initial orientation and monthly workshops. Gamoran and others studied six sites where teachers and educational researchers collaborated to reform science and mathematics teaching, focusing on teaching for understanding. Classroom and field-based "lab work" is conceptualized as central components of (2004). Bruner, J. Reston, VA: Association of Teacher Educators. School districts, teachers, and others may want to consider these examples, but further research is needed to determine their scope and effectiveness. What does research tell us about learning in high school science labs? Building on existing teacher internship programs at several of the national laboratories, the program will engage teachers as summer research associates at the laboratories, beginning with a four-week stint the first summer, followed by shorter two-week internships the following two summers (U.S. Department of Energy, 2004). 61-74). Songer, C., and Mintzes, J. Trumbull, D., and Kerr, P. (1993). Gess-Newsome, J., and Lederman, N. (1993). In contrast to these short, ineffective approaches, consensus is growing in the research about key features of high-quality professional development for mathematics and science teachers (DeSimone, Porter, Garet, Yoon, and Birman, 2002; DeSimone et al., 2003, p. 10): New forms of professional development (i.e., study group, teacher network, mentoring, or task force, internship, or individual research project with a scientist) in contrast to the traditional workshop or conference. Active learning opportunities focused on analysis of teaching and learning. The 2000 National Survey of Science and Mathematics Education: Compendium of tables. Available at: http://www7.nationalacademies.org/bose/June_3-4_2004_High_School_Labs_Meeting_Agenda.html [accessed May 2005]. Is there a shortage among mathematics and science teachers? 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. Goldhaber, D.D., and Brewer, D.J. Science teachers behavior in the classroom is influenced by the science curriculum, educational standards, and other factors, such as time constraints and the availability of facilities and supplies. in a limited range of laboratory experiences that do not follow the principles of instructional design identified in Chapter 3. A focus on deepening teachers knowledge of science or mathematics. Further research is needed to inform design of professional development that can effectively support improvements in teachers laboratory instruction. Guiding students to formulate their own research questions and design appropriate investigations requires sophisticated knowledge in all four of the domains we have identified. Requirements for professional development of in-service science teachers differ widely from state to state. Teachers help their colleagues by sharing instructional resources. They must guide and focus ongoing discussion and reflection with individuals, laboratory groups, and the entire class. They found that a heat-flow model was better able to connect to middle school students knowledge about heat and temperature than a molecular-kinetic model (Linn, Davis, and Bell, 2004). Loucks-Horsley, Love, Stiles, Mundry, and Hewson (2003) provide a detailed design framework for professional development and descriptions of case studies, identifying strategies for improving science teaching that may be applicable to improving laboratory teaching. Journal of Research in Science Teaching, 20, 745-754. Scientific laboratories, college and university science departments, and science museums have launched efforts to support high school science teachers in improving laboratory teaching. High school science laboratories. The design of this professional development program incorporated the principle of integrating laboratory experiences into the stream of instruction and the goal of providing a full range of laboratory experiences, including opportunities for students to participate in developing research questions and procedures. (2001). Effects of professional development on teachers instruction: Results from a three-year longitudinal study. Evaluating the evidence. In addition, there is little research on whether use of block scheduling influences teachers instruction or enhances student learning. The authors concluded that professional development activities that are short-term interventions have virtually no effect on teachers behaviors in leading laboratory experiences. the photo below). These might include websites, instructional materials, readings, or other resources to use with students. It may also be because teachers lack the content knowledge, pedagogical content knowledge, general pedagogical knowledge, and knowledge of assessment required to lead such discussions (Maienschein, 2004; Windschitl, 2004). Maienschein, J. Education Economics, 7(3), 199-208. (1994). National Research Council. (2001). The research also indicates that undergraduate laboratory work, like the laboratory experiences of high school students, often focuses on detailed procedures rather than clear learning goals (Hegarty-Hazel, 1990; Sutman, Schmuckler, Hilosky, Priestley, and Priestley, 1996). Also, you can type in a page number and press Enter to go directly to that page in the book. Science Education, 85(3), 263-278. In many cases teachers ranked in-service training as their least effective source of learning (Windschitl, 2004, p. 16; emphasis in original). 9-13 Thus, medical laboratory professionals can be key members of the interprofessional health care team. (1998). The laboratory has been given a central and distinctive role in science education, and science educators have suggested that there are rich benefits in learning from using laboratory activities. 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. Synergy research and knowledge integration. Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). 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.

When asked whether they had time during the regular school week to work with colleagues on the curriculum and teaching, 69 percent of high school teachers disagreed and 4 percent had no opinion, leaving only 28 percent who agreed. Based on feedback from you, our users, we've made some improvements that make it easier than ever to read thousands of publications on our website. Rockville, MD: Westat. Science Education, 77, 261-278. What can they contribute to science learning? Some individual teachers told our committee that they did not have adequate preparation and cleanup time.

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. Time constraints can also discourage teachers from the challenges of setting up and testing laboratory equipment and materials. Educational Policy, 14(3), 331-356. Shulman (1986, p. 8) has defined pedagogical content knowledge as: [A] special amalgam of content and pedagogy that is uniquely the province of teachers, their own form of professional understanding. You're looking at OpenBook, NAP.edu's online reading room since 1999. Block scheduling is one approach schools have used to provide longer periods of time for laboratory activities and discussion. The degree to which teachers themselves have attained the goals we speak of in this report is likely to influence their laboratory teaching and the extent to which their students progress toward these goals. Another analysis of the data from the National Center for Education Statistics found that students in high schools with higher concentrations of minority students and poor students were more likely than students in other high schools to be taught science by a teacher without a major or minor in the subject being taught (U.S. Department of Education, 2004). 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). Hirsch, E., Koppich, J.E., and Knapp, M.S. Expertise in science alone also does not ensure that teachers will be able to anticipate which concepts will pose the greatest difficulty for students and design instruction accordingly. Further research is needed to inform design of laboratory-focused teacher professional development that can support teachers in improving laboratory instruction. They must consider how to clearly communicate the learning goals of the laboratory experience to their students. Marjolein Dobber a. , Rosanne Zwart b. , Marijn Tanis a b 1. , Bert van Oers a.
