Qualified high school teachers will have opportunities to work and learn at the Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, and Pacific Northwest National Laboratories and at the National Renewable Energy Laboratory. ), Constructivism in education. workincluding verification workrequires deep knowledge of the specific science concepts and science processes involved in such work (Millar, 2004). The National Survey of Science and Mathematics Education: Trends from 1977 to 2000. However, their study was criticized for being conducted in laboratory environment (Taylor, Ntoumanis, . Available at: http://www7.nationalacademies.org/bose/June_3-4_2004_High_School_Labs_Meeting_Agenda.html [accessed May 2005]. In L.P. Steffe and J. Gale (Eds. little information is available on the effectiveness of these efforts. (2004). Teachers College Record, 105(3), 465-489. 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. It means focusing the students own questions. 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). ), The student laboratory and the curriculum (pp. The impact of longer term intervention on reforming the approaches to instructions in chemistry by urban teachers of physical and life sciences at the secondary school level. Project ICAN: Inquiry, Context, and Nature of Science. 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. Respecting childrens own ideas. However, formulating such questions can be difficult (National Research Council, 2001a, 2001b). 7082.) (2003). Science Education, 77(3), 301-317. A teacher knows how to work well as part of a team. It is ultimately the role of Laboratory Assistant to facilitate the safe and efficient delivery of the curriculum designed by the teacher. Journal of Science Education and Technology, 13(2), 189-206. 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. 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. (2002). ReviewLiterature review: The role of the teacher in inquiry-based education. Committee on Techniques for the Enhancement of Human Performance: Occupational Analysis. 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). The teachers skills in posing questions and leading discussions affect students ability to build meaning from their laboratory experiences. The role of the laboratory in science learning. Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. Marjolein Dobber a. , Rosanne Zwart b. , Marijn Tanis a b 1. , Bert van Oers a. Journal of Research in Science Teaching, 20, 745-754. It aims to support teachers to improve their teaching skills for active learning in university science laboratory courses. 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). (2003). Volunteers receive training, a sourcebook of activities appropriate for middle school students, a kit of science materials, and a set of videotapes. The teachers, all biology majors, could only list the courses they had taken as a way to organize their fields. A research agenda. They must guide and focus ongoing discussion and reflection with individuals, laboratory groups, and the entire class. They must address the challenge of helping students to simultaneously develop scientific reasoning, master science subject matter and progress toward the other goals of laboratory experiences. Is laboratory-based instruction in beginning college-level chemistry worth the effort and expense? The elementary level science methods course: Breeding ground of an apprehension toward science? Gamoran and others studied six sites where teachers and educational researchers collaborated to reform science and mathematics teaching, focusing on teaching for understanding. Millar, R., and Driver, R. (1987). The. University of Michigan Physics Department: GSI training course. 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. (2002). Washington, DC: Author. To search the entire text of this book, type in your search term here and press Enter. There are promising examples of teacher professional development focused on laboratory experiences. It may be useful, however, to begin . Schwartz, R., and Lederman, N. (2002). Helping students attain the learning goals of laboratory experiences requires their teachers to have broad and deep understanding of both the processes and outcomes of scientific research. Duration (total contact hours, span of time). East Lansing, MI: National Center for Research in Teacher Education. 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. Does teacher certification matter? Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). Journal of Research in Science Teaching. Journal of the Learning Sciences, 6(2), 227-269. (2004). 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. In addition, there is little research on whether use of block scheduling influences teachers instruction or enhances student learning. Teacher and classroom context effects on student achievement: Implications for teacher evaluation. Lederman, N.G. Teachers require several types of knowledge to succeed in these multiple activities, including (1) science content knowledge, (2) pedagogical content knowledge, (3) general pedagogical knowledge, and (4) knowledge of appropriate assessment techniques to measure student learning in laboratory education. Student outcomes and the professional preparation of eighth-grade teachers in science and mathematics: NSF/NELS. For example, Western science promotes a critical and questioning stance, and these values and attitudes may be discontinuous with the norms of cultures that favor cooperation, social and emotional support, consensus building, and acceptance of the authority (p. 470). After receiving his BEd and MEd degrees from the same university in 1985 and 1986 respectively he started his teaching career as Mathematics and Science teacher in 1989 at Windhoek High . Zip. Research on the efficacy of strategies used for professional development related specifically to laboratory experiences, however, is not readily available. In many cases teachers ranked in-service training as their least effective source of learning (Windschitl, 2004, p. 16; emphasis in original). A survey of students, teachers, and volunteers yielded positive results. Science Teacher (October), 40-43. Wright, S.P., Horn, S., and Sanders, W. (1997). National Center for Family and Community Connections with Schools. Life in science laboratory classrooms at the tertiary level. How can school organization contribute to effective laboratory teaching. Weiss, I.R., Pasley, J.D., Smith, P.S., Banilower, E.R., and Heck, D.J. It means figuring out what students comprehend by listening to them during their discussions about science. 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. Before its too late: A report to the nation from the national commission on mathematics and science teaching for the 21st century. Quantitative approach was used to investigate effects of teaching science subjects in absence of science laboratory and to. 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. 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. At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory Journal of Personnel Evaluation in Education, 11(1), 57-67. Songer, C., and Mintzes, J. At the same time, teachers must address logistical and practical concerns, such as obtaining and storing supplies and maintaining laboratory safety. Maienschein, J. In M.D. Do all student have access to laboratory experiences? Washington, DC: American Psychological Association. Clark, R.L., Clough, M.P., and Berg, C.A. Guiding students through the complexity and ambiguity of empirical. Journal of Science Education and Technology, 4(2), 103-126. 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). No national survey data are available to indicate whether science teachers receive adequate preparation time or assistance from trained laboratory technicians. They should be proactive in every aspect of laboratory safety, making safety a priority. 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. Linn describes aspects of the model as pragmatic principles of heat that are more accessible goals than the microscopic view of heat that is commonly taught (Linn, 1997, p. 410). What can they contribute to science learning? 1071 Palmer Commons Laboratory Learning: An Inservice Institute. Hanusek, E., Kain, J., and Rivkin, S. (1999). School administrators play a critical role in supporting the successful integration of laboratory experiences in high school science by providing improved approaches to professional development and adequate time for teacher planning and implementation of laboratory experiences. Coherence (consistency with teachers goals, state standards, and assessments). 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. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. Science teachers may be modeling instructional practices they themselves witnessed or experienced firsthand as students in college science classes. Baumgartner, E. (2004). In M.C. Some individual teachers told our committee that they did not have adequate preparation and cleanup time. 100 Washtenaw Ave. 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. Fraser and K.G. Establishing classroom, lab, and field trip rules and regulations and ensuring that . Available at: http://www.nsta.org/positionstatementandpsid=16 [accessed Oct. 2004]. 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. 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. 13-Week Science Methodology Course. Seattle: University of Washington, Center for the Study of Teaching and Policy. Laboratory activities have long had a distinct and central role in the science curriculum as a means of making sense of the natural world. 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. 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). Fred Hutchinson Cancer Research Center. This is not a simple task (National Research Council, 2001b, p. 79): To accurately gauge student understanding requires that teachers engage in questioning and listen carefully to student responses. Thousand Oaks, CA: Corwin Press. They felt confident to guide their students through the same process, where there is no right answer.. Cobus van Breda was born and schooled in Windhoek, Namibia. Chapel Hill, NC: Horizon Research. Further research is needed to assess the extent to which such programs help teachers develop the knowledge and skills required to lead laboratory experiences in ways that help students master science subject matter and progress toward other science learning goals. Educational Evaluation and Policy Analysis, 24(2), 81-112. Abstract available at: http://epx.sagepub.com/cgi/content/abstract/17/5/613 [accessed May 2005]. One study illustrates undergraduate students lack of exposure to the full range of scientists activities, and the potential benefits of engaging them in a broader range of experiences. Moreover, the teacher console (keyboard) is usually fitted with a tape recorder to monitoring each compartment in the class by the teacher headset and an intercom facility to enable 2-way communication between the teacher and his/her students individually. Few professional development programs for science teachers emphasize laboratory instruction. U.S. Department of Education. (2004). Chaney, B. Teachers need to use data drawn from conversations, observations, and previous student work to make informed decisions about how to help them move toward desired goals. Primary science: Taking the plunge. International Journal of Science Education, 18(7), 775-790. Participation of groups of teachers from the same school, department, or grade. 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. At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory work, and the case for laboratory . About this Course. Familiarity with the evidence or principles of a complex theory does not ensure that a teacher has a sound understanding of concepts that are meaningful to high school students and that she or he will be capable of leading students to change their ideas by critiquing each others investigations as they make sense of phenomena in their everyday lives. Implications of teachers beliefs about the nature of science: Comparisons of the beliefs of scientists, secondary science teachers, and elementary science teachers. Retired scientists and engineers: Providing in-classroom support to K-12 science teachers. Boys and girls in the performance-based classroom: Whos doing the performing? Linn, E.A. (1995). (2001). MyNAP members SAVE 10% off online. Mortimer, E., and Scott, P. (2003). Other studies have also found that most teachers do not experience sustained professional development and that they view it as ineffective (Windschitl, 2004). Shulman, L.S. Show this book's table of contents, where you can jump to any chapter by name. Hudson, S.B., McMahon, K.C., and Overstreet, C.M. Prepare lab apparatus and equipment. goals of laboratory experiences. Most states do not regulate the quality and content of professional development required for renewal of teaching certificates (Hirsch, Koppich, and Knapp, 2001). The Fermi National Accelerator Laboratory has provided professional development programs for science teachers for several years (Javonovic and King, 1998). Center for Education.
