Participation of groups of teachers from the same school, department, or grade. Formulating research questions appropriate for a science classroom and leading student discussions are two important places where the interaction of the four types of knowledge is most evident. To be successful in leading students across the range of laboratory experiences we have described, teachers must choose laboratory experiences that are appropriate at any given time. Full article: Teacher motivation: Definition, research development and 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. Davis, and P. Bell (Eds. Science Teacher Job Description - Betterteam an increasingly important aspect of their general pedagogical knowledge. 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). Teachers require deep conceptual knowledge of a science discipline not only to lead laboratory experiences that are designed according to the research, but also to lead a full range of laboratory experiences reflecting the range of activities of scientists (see Chapter 1). Associations of science teachers have taken differing positions on how administrators can best support teachers in preparing for and cleaning up after laboratory experiences. McDiarmid, G.S., Ball, D.L., and Anderson, C.W. Linn, E.A. They should advise teachers where any concerns arise regarding safety, scheduling or resourcing of 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. 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. (2004). 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. Learning to teach inquiry science in a technology-based environment: A case study. The role of practical work in the teaching and learning of science. (2001b). Preordained science and student autonomy: The nature of laboratory tasks in physics classrooms. In this approach, school administrators recognize that leadership for improved teaching and learning is distributed throughout the school and district and does not rest on traditional hierarchies. Gallagher, J. Wright, S.P., Horn, S., and Sanders, W. (1997). The paraprofessional would help with setup, cleanup, community contacts, searching for resources, and other types of support (National Science Teachers Association, 1990). 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. The Role of Laboratory in Science Teaching and Learning Supovitz, J.A., Mayer, D.P., and Kahle, J. American Educational Research Journal 35(3), 477-496. Tobin (Eds. Some individual teachers told our committee that they did not have adequate preparation and cleanup time. Available at: http://www.nsta.org/positionstatementandpsid=16 [accessed Oct. 2004]. Cobus van Breda was born and schooled in Windhoek, Namibia. Prepare lab apparatus and equipment. 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. . Arrangements must be made with Instructor to cover unavoidable absences or planned breaks. (2000). 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. laboratory notebooks, essays, and portfolios (Hein and Price, 1994; Gitomer and Duschl, 1998; Harlen, 2000, 2001). Do all student have access to laboratory experiences? Seattle: University of Washington, Center for the Study of Teaching and Policy. The traditional didactic pedagogy to which teacher candidates are exposed in university science courses equips learners with only minimal conceptual understandings of their science disciplines (Duschl, 1983; Gallagher, 1991; Pomeroy, 1993, cited in Windschitl, 2004). Improving science teachers conceptions of nature of science: A critical review of the literature. Transforming teaching in math and science: How schools and districts can support change. In these discussions, the teacher helps students to resolve dissonances between the way they initially understood a phenomenon and the new evidence. One study found that schools that provide more support to new teachers, including such professional development activities as induction and mentoring, have lower turnover rates (Ingersoll, 2003, p. 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. All of these factors indirectly affect the academic achievement of the students. 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. van Zee, E., and Minstrell, J.

Is laboratory-based instruction in beginning college-level chemistry worth the effort and expense? They lock up all the reagents and unplug all electrical equipment to minimize the chances of accidents and fires. (1998). This lack of discussion may be due to the fact that high school science teachers depend heavily on the use of textbooks and accompanying laboratory manuals (Smith et al., 2002), which rarely include discussions. Hanusek, E., Kain, J., and Rivkin, S. (1999). Learning in the laboratory: Some thoughts from the literature. One study indicated that significant change in teaching practice required about 80 hours of professional development (Supovitz and Turner, 2000). Program faculty report that many teachers tend to dwell on hands-on activities with their students at the expense of linking them with the nature of science and with abilities associated with scientific inquiry. Washington, DC: National Academy Press. Coffey, Everyday assessment in the science classroom (pp. Finally, adequate time is essential for student learning in laboratory experiences. Designing a community of young learners: Theoretical and practical lessons. 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. 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. Between sessions, teacher participants reflected on what they were learning and applied some of it in their classrooms, following the active learning approach suggested by the research on professional development for science teachers. 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). Currently, few teachers lead this type of sense-making discussion (Smith, Banilower, McMahon, and Weiss, 2002). in a limited range of laboratory experiences that do not follow the principles of instructional design identified in Chapter 3.

Volunteers receive training, a sourcebook of activities appropriate for middle school students, a kit of science materials, and a set of videotapes. Journal of Chemical Education, 75(1), 100-104. Driver, R. (1995). The mystery of good teaching: Surveying the evidence on student achievement and teachers characteristics. Deng, Z. Reporting on a post-institute survey, McComas and Colburn note that a surprising number of teachers felt that the safety sessions were most important (p. 121) (no numbers were reported). Other duties include reinforcing laboratory housekeeping and safety protocol, coordinating with other engineering departments, and receiving, installing, and maintaining laboratory supplies and equipment. Improving high school science teachers capacity to lead laboratory experiences effectively is critical to advancing the educational goals of these experiences. This is knowledge drawn from learning theory and research that helps to explain how students develop understanding of scientific ideas. Chaney, B. Can schools narrow the black-white test score gap? Ready to take your reading offline? Using questioning to assess and foster student thinking. Specifically, it challenges the assumption that having a college degree in science, by itself, is sufficient to teach high school science. Many schools schedule eight 40- to 55-minute class periods, so that following the AAPT guidelines would allow physics teachers two preparation periods. The.

Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. They also modeled longer postlaboratory activities focused on using student data and observations as the engine for further instruction. Perhaps this is because, among scientists, decisions about the kinds of questions to be asked and the kinds of answers to be sought are often developed by the scientific community rather than by an isolated individual (Millar, 2004). Laboratory Schools: History Teacher, High School Some school and school district officials may be reluctant to invest in sustained professional development for science teachers because they fear losing their investments if trained teachers leave for other jobs. Even teachers who have majored in science may be limited in their ability to lead effective laboratory experiences, because their undergraduate science preparation provided only weak knowledge of science content and included only weak laboratory experiences. The laboratory in science education: Foundations for the twenty-first century. Undergraduate science departments rarely provide future science teachers with laboratory experiences that follow the design principles derived from recent researchintegrated into the flow of instruction, focused on clear learning goals, aimed at the learning of science content and science process, with ongoing opportunities for reflection and discussion. Literature review: The role of the teacher in inquiry-based education Journal of Research in Science Teaching, 29, 51-61. Active learning opportunities focused on analysis of teaching and learning. In 1999-2000, 39.4 percent of all physics teachers in public high schools had neither a major nor a minor in physics, 59.9 percent of all public high school geology teachers lacked a major or minor in geology, 35.7 percent of chemistry teachers lacked a major or minor in that field, and 21.7 percent of biology teachers had neither a major nor a minor in biology (National Center for Education Statistics, 2004). Studies focusing specifically on science teacher quality and student achievement are somewhat more conclusive. Educational Evaluation and Policy Analysis, 24(2), 81-112. Review of Educational Research, 52 (2), 201-217. What does research tell us about learning in high school science labs? A teachers academic science preparation appears to affect student science achievement generally. 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).

PDF The Use of Laboratory Method in Teaching Secondary School - IJSER Goldhaber, D.D., and Brewer, D.J. As we have discussed, teachers face an ongoing tension between allowing students greater autonomy in the laboratory and guiding them toward accepted scientific knowledge. They felt confident to guide their students through the same process, where there is no right answer.. This chapter describes some of the factors contributing to the weakness of current laboratory experiences. 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. 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 Higher Education Chemistry (RSC), 5 (2), 42-51. 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. Westbrook, S., and Marek, E. (1992). The effects of professional development on science teaching practices and classroom culture. Glagovich, N., and Swierczynski, A. 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). Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. However, formulating such questions can be difficult (National Research Council, 2001a, 2001b). After completion of the course, teachers classroom behaviors were videotaped and analyzed against traditional and reformed instructional strategies. DeSimone and others conducted a three-year longitudinal study of professional development in science and mathematics provided by school districts. (1998). The teacher strives to fathom what the student is saying and what is implied about the students knowledge in his or her statements, questions, work and actions. 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). Literature review: The role of the teacher in inquiry-based education.

Lunetta, V.N. 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). Once on the job, science teachers have few opportunities to improve their laboratory teaching. Javonovic, J., and King, S.S. (1998). 61-74). Emerging issues and practices in science assessment.

Although no national information is available about high school teachers participation in laboratory internship programs, a recent survey found that only 1 in 10 novice elementary school teachers had participated in internship programs in which they worked directly with scientists or engineers. Laboratory teaching assumes that first-hand experience in observation and manipulation of the materials of science is superior to other methods of developing understanding and appreciation. 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.

For example, HHMI has funded summer teacher training workshops at the Cold Spring Harbor Laboratory for many years, and also supports an ongoing partnership between the Fred Hutchinson Cancer Research Center and the Seattle, Washington, public schools (Fred Hutchinson Cancer Research Center, 2003). However, compared with other types of professionals, a higher proportion of teachers leave their positions each year. Journal of Science Education and Technology, 4(2), 103-126.

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. This book looks at a range of questions about how laboratory experiences fit into U.S. high schools: With increased attention to the U.S. education system and student outcomes, no part of the high school curriculum should escape scrutiny. a deeper understanding of abstract concepts and theories gained by experiencing and visualising them as authentic phenomena the skills of scientific enquiry and problem-solving, including: recognising and defining a problem formulating hypotheses designing experiments collecting data through observation and/or experimentation interpreting data In doing so, they showed teachers how laboratory experiences.

One study found that having an advanced degree in science was associated with increased student science learning from the 8th to the 10th grade (Goldhaber and Brewer, 1997). The condition of education. No national survey data are available to indicate whether science teachers receive adequate preparation time or assistance from trained laboratory technicians. Teachers need to decide what kind of phenomena are important and appropriate for students to study as well as the degree of structure their students require. 7082.)
