Students cannot be admitted to the classroom until you arrive. Data from the 2000 National Survey of Science and Mathematics Education. The Biological Sciences Curriculum Study, a science curriculum development organization, has long been engaged in the preservice education of science teachers and also offers professional development for inservice teachers. Is laboratory-based instruction in beginning college-level chemistry worth the effort and expense? Teacher and classroom context effects on student achievement: Implications for teacher evaluation. A student lab assistant ensures that students do not practice any unsafe behaviors in the lab. Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. Paper presented at the National Association for Research in Science Teaching meeting, March 23, Chicago, IL. Center for Education. It is important for the teacher to be a good learner so as to keep up with the changes. The Higher Education Chemistry (RSC), 5 (2), 42-51. Report equipment problems in writing to the Lab Staff. 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. Google Scholar Rethinking laboratories. Available at: http://www.horizon-research.com/reports/2002/2000survey/trends.php [accessed May 2005]. They also spend a week doing laboratory research with a scientist mentor at the Fred Hutchinson Center or one of several other participating public and private research institutions in Seattle. Scientific laboratories, college and university science departments, and science museums have launched efforts to support high school science teachers in improving laboratory teaching.

At Vanderbilt University, Catley conducts a summer-long course on research in organismal biology. 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. In M.D. Mathematics and science teachers reported more frequently than other teachers that job dissatisfaction was the reason they left their jobs. Teachers require a deep understanding of scientific processes in order to guide students procedures and formulation of research questions, as well as deep understanding of science concepts in order to guide them toward subject matter understanding and other learning goals. Tobin (Eds. Large majorities of students indicated that the program had increased their interest in science, while large majorities of teachers said they would recommend the program to other teachers and that the volunteers had had a beneficial effect on their science teaching. They also face uncertainty about how many variables students should struggle with and how much to narrow the context and procedures of the investigation. (1997). National Science Teachers Association. (1986). View our suggested citation for this chapter. Further research is needed to inform design of laboratory-focused teacher professional development that can support teachers in improving laboratory instruction. In addition, they found that commercially available laboratory manuals failed to provide cognitively challenging activities that might help to bridge the gap between teachers lack of knowledge and improved laboratory experiences (McComas and Colburn, 1995, p. 120). These school-based teacher communities, in turn, not only supported teachers in improving their teaching practices, but also helped them create new resources, such as new curricula. 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. 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. Committee on High School Biology Education, Commission on Life Sciences. teacher in the classroom and thus cause tension like tools, materials, negative working conditions, student violence on teachers, increasing teacher expectations and tiredness of teacher. (2001). Participation of groups of teachers from the same school, department, or grade. (1998). Finally, an . 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. Science Teacher (October), 40-43. The investigators found that professional development focused. ), The black-white test score gap. 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. Chapel Hill, NC: Horizon Research. take place in a school laboratory, but could also occur in an out-of-school setting, such as the student's home or in the field (e.g. Resource Provider. (2001). 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. A Japanese high school language lab shows students' positions Pre-service biology teachers knowledge structures as a function of professional teacher education: A year-long assessment. Davis, and P. Bell (Eds. workincluding verification workrequires deep knowledge of the specific science concepts and science processes involved in such work (Millar, 2004). University of Michigan Physics Department: GSI training course. Biology student teachers' ideas about purpose of laboratory work Key words: Laboratory, chemistry, teaching, achievement, students.

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). It means focusing the students own questions. 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). Journal of Research in Science Teaching, 29, 51-61. ), Constructivism in education. Synergy research and knowledge integration. The limited quality and availability of professional development focusing on laboratory teaching is a reflection of the weaknesses in the larger system of professional development for science teachers. The role of the laboratory in science learning. McComas, W.F., and Colburn, A.I. Knoxville: University of Tennessee Value-Added Research and Assessment Center. Available at: http://www7.nationalacademies.org/bose/June_3-4_2004_High_School_Labs_Meeting_Agenda.html [accessed May 2005]. 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. (2003). Shared teacher planning time may be a critical support for improved laboratory teaching, because of the unique nature of laboratory education. (2004). (2002). Minstrell, J., and van Zee, E.H. (2003). It means figuring out what students comprehend by listening to them during their discussions about science. (2001b). To date, however, few high schools have adopted such research-based science curricula, and many teachers and school administrators are unaware of them (Tushnet et al., 2000; Baumgartner, 2004). Sign up for email notifications and we'll let you know about new publications in your areas of interest when they're released. (2003). 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). 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. 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). [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. In doing so, they showed teachers how laboratory experiences. Available at: http://www.nces.ed.gov/programs/coe/2004/section4/indicator24.asp [accessed Feb. 2005]. Presentation to the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. Lee, O., and Fradd, S.H. Rather, learning is an active process which goes on within the students by guiding the learning . The literature provides an overview of a range of factors motivating and demotivating pre-service and in-service teachers, and the role teacher motivation plays in possible links with other areas. Erroneous ideas about respiration: The teacher factor. 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. London, England: Kluwer Academic. Hillsdale, NJ: Lawrence Erlbaum. Atkin, P. Black, and J. Coffey (Eds.). Methods of assessing student learning in laboratory activities include systematically observing and evaluating students performance in specific laboratory tasks and longer term laboratory investigations. Equity for linguistically and culturally diverse students in science education. The role of teacher in the acquisition of scientific knowledge in Secondary School Science class cannot be underestimated. Collaborator. Current professional development for science teachers is uneven in quantity and quality and places little emphasis on laboratory teaching. In a guided-inquiry laboratory (GIL), the teacher provides the students with a question, or set of questions, and the students design an experiment to address the question(s). Sanders, W.L., and Rivers, J.C. (1996). In contrast, a physicist might use mathematics to describe or represent the reflection, transmission, and absorption of light. Teachers design and carry out an open-ended field research project, of their own choosing. National Research Council. It will show you how laboratory sessions can differ with respect to their aim and expected learning . Research conducted in teacher education programs provides some evidence of the quality of preservice science education (Windschitl, 2004). The purpose of this paper is to explore and discuss the role of practical work in the teaching and learning of science at school level. Despite the weakness of current professional development for laboratory teaching, a growing body of research indicates that it is possible to develop and implement professional development that would support improved laboratory teaching and learning. Review of Educational Research, 52 (2), 201-217. ), International handbook of science education (pp. Assistants show the students how to handle chemical spills, dispose of broken glassware and get rid of non-hazardous and chemical waste . Can schools narrow the black-white test score gap? Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). Among those who had, an overwhelming majority said the experience had helped them better understand science content and improved both their teaching practice and their enthusiasm (Bayer Corporation, 2004). Few professional development programs for science teachers emphasize laboratory instruction. Washington, DC: Author. Hofstein, A., and Lunetta, V.N. They surveyed a sample of 207 teachers in 30 schools, 10 districts, and 5 states to examine features of professional development and its effects on teaching practice from 1996 to 1999 (DeSimone et al., 2002). Goldhaber, D.D. light, such as reflection, transmission, and absorption. Emerging issues and practices in science assessment. Among the volunteers, 97 percent said they would recommend RE-SEED to a colleague, and most said that the training, placement in schools, and support from staff had made their time well spent (Zahopoulos, 2003).

Coffey, Everyday assessment in the science classroom (pp. With the support of the Howard Hughes Medical Institute (HHMI), several medical colleges and research institutions provide laboratory-based science experiences for science teachers and their students. Chapel Hill, NC : Horizon Research. Slotta, J.D. But those connections are not enough: science sense-making discourse must also help students to develop understanding of a given science concept and create links between theory and observable phenomena. an increasingly important aspect of their general pedagogical knowledge.
