The National Science Teachers Association takes a slightly different position, suggesting that administrators provide teachers with a competent paraprofessional. ReviewLiterature review: The role of the teacher in inquiry-based education. Classroom assessment and the national science education standards. What can they contribute to science learning? (2004). However, an analysis of national survey data indicates that teachers in block schedules do not incorporate more laboratory experiences into their instruction (Smith, 2004). Schwartz, R., and Lederman, N. (2002). The poor quality of laboratory experiences of most high school students today results partly from the challenges that laboratory teaching and learning pose to school administrators. A supportive school administration could help teachers overcome their isolation and learn from each other by providing time and space to reflect on their laboratory teaching and on student learning in the company of colleagues (Gamoran, 2004). 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). Teacher participants at the institute experienced firsthand learning as students in several laboratory sessions led by high school instructors who were regarded as master laboratory teachers.

Mahwah, NJ: Lawrence Earlbaum. Center for Education. light, such as reflection, transmission, and absorption. Further research is needed to inform design of professional development that can effectively support improvements in teachers laboratory instruction. Coherence (consistency with teachers goals, state standards, and assessments). We begin by identifying some of the knowledge and skills required to lead laboratory experiences aligned with the goals and design principles we have identified. [I]t represents the blending of content and pedagogy into an understanding of how particular topics, problems, or issues are organized, represented and adapted to the diverse interests and abilities of learners, and presented for instruction. 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. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. However, a review of the literature five years later revealed no widespread efforts to improve laboratory education for either preservice or in-service teachers (McComas and Colburn, 1995). National Research Council. One study found that, when laboratories were easily accessible, 14- and 15-year-old students who used the facilities during their free time reported increased interest in academics and took advanced science courses (Henderson and Mapp, 2002). This chapter describes some of the factors contributing to the weakness of current laboratory experiences. (2004). Haase, B.S. (2001). Teaching Assistant Responsibilities Arrive on time & remain in lab. To make these choices, they must be aware not only of their own capabilities, but also of students needs and readiness to engage in the various types of laboratory experiences. National Research Council. Goldhaber, D.D., and Brewer, D.J. However, experts do not agree on which aspects of teacher qualitysuch as having an academic major in the subject taught, holding a state teaching certificate, having a certain number of years of teaching experience, or other unknown factorscontribute to their students academic achievement (Darling-Hammond, Berry, and Thoreson, 2001; Goldhaber and Brewer, 2001).

H., & Al-Shuaili, A. to the content of textbooks, to visual aids, or to laboratory equipment. Washington, DC: National Academy Press. Leading laboratory experiences is a demanding task requiring teachers to have sophisticated knowledge of science content and process, how students learn science, assessment of students learning, and how to design instruction to support the multiple goals of science education. Wright, S.P., Horn, S., and Sanders, W. (1997). DeSimone, L.M., Porter, A.S., Garet, M.S., Yoon, K.S., and Birman, B. Washington, DC: American Psychological Association. Sanders, M. (1993). Gamoran and colleagues found that, although the educational researchers provided an infusion of expertise from outside each of the six school sites, the professional development created in collaboration with the local schools had its greatest impact in supporting local teachers in developing their own communities. Tobin (Eds. Gather people close to focus them on what you are doing and consider the range of visual and auditory needs among your students to provide equitable access to the demonstration. To lead laboratory experiences that incorporate ongoing student discussion and reflection and that focus on clear, attainable learning goals, teachers require pedagogical content knowledge. The effects of instruction on college nonmajors conceptions of respiration and photosynthesis. Chemistry laboratories play an essential role in the education of undergraduate Science, Technology, Engineering, and Mathematics (STEM) and non-STEM students. Laboratory activities have long had a distinct and central role in the science curriculum as a means of making sense of the natural world. Undergraduate science students, including preservice teachers, engage. Windschitl, M. (2004). Journal of College Science Teaching, 33(6). A Japanese high school language lab shows students' positions Their previous, closely prescribed laboratory experiences had not helped them to understand that there are many different ways to effect a particular chemical transformation.

Laboratory work also gives the students the opportunity to experience science by using scientific research procedures. Few professional development programs for science teachers emphasize laboratory instruction. Only a few high school students are sufficiently advanced in their knowledge of science to serve as an effective scientific community in formulating such questions. However, the undergraduate education of future science teachers does not currently prepare them for effective laboratory teaching. Zahopoulos, C. (2003). Internet environments for science education. Educational Evaluation and Policy Analysis, 24(2), 81-112. Presentation to the NRC Committee on High School Science Laboratories, March 29, Washington, DC. 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. Reston, VA: Association of Teacher Educators. A new wave of evidenceThe impact of school, family, and community connections in student achievement. Mahwah, NJ: Lawrence Erlbaum. 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. 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). 100 Washtenaw Ave. Further research is needed to evaluate these and other efforts to link scientists with K-12 education. ROLE DESCRIPTION Education Support Employee Laboratory Assistant workincluding verification workrequires deep knowledge of the specific science concepts and science processes involved in such work (Millar, 2004). Committee on High School Biology Education, Commission on Life Sciences. The final section concludes that there are many barriers to improving laboratory teaching and learning in the current school environment. Shared teacher planning time may be a critical support for improved laboratory teaching, because of the unique nature of laboratory education. (2002). Priestley, W., Priestley, H., and Schmuckler, J. It will show you how laboratory sessions can differ with respect to their aim and expected learning . Chaney, B. Data from a 2000 survey of science and mathematics education indicate that most current science teachers participate infrequently in professional development activities, and that many teachers view these activities as ineffective (Hudson, McMahon, and Overstreet, 2002). A cross-age study of student understanding of the concept of homeostasis. The effects of professional development on science teaching practices and classroom culture. At the same time, teachers must address logistical and practical concerns, such as obtaining and storing supplies and maintaining laboratory safety. 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. However, 66 percent of teachers indicated that they regularly shared ideas and materials with their colleagues, perhaps indicating that they do so on their own time, outside school hours (Hudson et al., 2002). 4. Gamoran and others studied six sites where teachers and educational researchers collaborated to reform science and mathematics teaching, focusing on teaching for understanding. The teachers ability to use sophisticated questioning techniques to bring about productive student-student and student-teacher discussions in all phases of the laboratory activity is a key factor in the extent to which the activity attains its goals (Minstrell and Van Zee, 2003). (2004). In this section, we describe the types of teacher knowledge and skills that may be required to lead a range of laboratory experiences aligned with our design principles, comparing the required skills with evidence about the current state of teachers knowledge and skills. Tobin, K.G. Abstract available at: http://epx.sagepub.com/cgi/content/abstract/17/5/613 [accessed May 2005]. (2004). In addition, some researchers argue that, although professional development expends resources (time, money, supplies), it also creates new human and social resources (Gamoran et al., 2003, p. 28). 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. It often consists mostly of one-day (or shorter) workshops focusing on how-to activities that are unlikely to challenge teachers beliefs about teaching and learning that support their current practice (DeSimone, Garet, Birman, Porter, and Yoon, 2003). Implications of teachers beliefs about the nature of science: Comparisons of the beliefs of scientists, secondary science teachers, and elementary science teachers. In a study of 100 preservice science teachers, only 20 percent reported having laboratory experiences that gave them opportunities to ask their own questions and to design their own science investigations (Windschitl, 2004). Raleigh: Science House, North Carolina State University. The research described above indicates that undergraduate laboratory experiences do not integrate learning of science content and science processes in ways that lead to deep conceptual understanding of science subject matter. (1998). Available at: http://www.educationnext.org/20021/50.html [accessed Feb. 2005]. American Association of Physics Teachers. New York: City College Workshop Center. For example, Northeastern University has established a program called RE-SEED (Retirees Enhancing Science Education through Experiments and Demonstration), which arranges for engineers, scientists, and other individuals with science backgrounds to assist middle school teachers with leading students in laboratory experiences. Deep disciplinary expertise is necessary to help students learn to use laboratory tools and procedures and to make observations and gather data. School districts, teachers, and others may want to consider these examples, but further research is needed to determine their scope and effectiveness.
