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). Gitomer, D.H., and Duschl, R.A. (1998). 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. Available at: http://www7.nationalacademies.org/bose/June_3-4_2004_High_School_Labs_Meeting_Agenda.html [accessed May 2005]. Hanusek, E., Kain, J., and Rivkin, S. (1999). It aims to support teachers to improve their teaching skills for active learning in university science laboratory courses. As discussed in Chapters 2 and 3, there are curricula that integrate laboratory experiences into the stream of instruction and follow the other instructional design principles. Requirements for professional development of in-service science teachers differ widely from state to state. (1997). Chapel Hill, NC: Horizon Research. Improving science teachers conceptions of nature of science: A critical review of the literature. Millar, R., and Driver, R. (1987). 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). Fred Hutchinson Cancer Research Center. Arlington, VA: National Science Teachers Association. The teaching communities that developed, with their new leaders, succeeded in obtaining additional resources (such as shared teacher planning time) from within the schools and districts (Gamoran et al., 2003) and also from outside of them. Teachers College Record, 105(3), 465-489. 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 . Lee, O., and Fradd, S.H. Science Teacher, September, 38-41. (2001). Science Education, 85(3), 263-278. Journal of Research in Science Teaching, 27, 761-776. Earn CE Get Involved Advocate/Support Your Profession Only 11 percent of responding teachers indicated that science teachers in their school regularly observed other science teachers. Educational Evaluation and Policy Analysis, 23(1), 57-77. 4. 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 The investigators found that professional development focused. 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. 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. Ingersoll, R. (2003). Science Education, 88, 28-54. Why staying ahead one chapter doesnt really work: Subject-specific pedagogy. 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). In a year-long study of prospective biology teachers (Gess-Newsome and Lederman, 1993), the participants reported never having thought about the central ideas of biology or the interrelationships among the topics. Participant teachers were also interviewed. Davis, and P. Bell (Eds. Deng, Z. What do they contribute to science learning? The research team focused the curriculum on helping students understand these principles, including flow principles, rate principles, total heat flow principles, and an integration principle. Retired scientists and engineers: Providing in-classroom support to K-12 science teachers. A three-way error components analysis of educational productivity. The authors of the review found that, when laboratory education is available, it focuses primarily on the care and use of laboratory equipment and laboratory safety. Learning in the laboratory: Some thoughts from the literature. 100 Washtenaw Ave. At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory Windschitl, M. (2004). 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). ), International handbook of science education (pp. This would require both a major changes in undergraduate science education, including provision of a range of effective laboratory experiences for future teachers, and developing more comprehensive systems of support for teachers. NSTA position statement: Laboratory science. Committee on Classroom Assessment and the National Science Education Standards, J.M. CrossRef Google Scholar Johnstone, A. H., & Al-Shuaili, A. teacher is teaching both chemistry and physics, requiring more preparation time (American Association of Physics Teachers, 2002). 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. International Journal of Science Education, 18(7), 775-790. The distinction between key ideas in teaching school physics and key ideas in the discipline of physics. 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). The research comprised both quantitative and qualitative approaches. Chapel Hill, NC : Horizon Research. 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). New York: Pergamon. 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. The teachers, all biology majors, could only list the courses they had taken as a way to organize their fields. Portsmouth, NH: Heinemann. 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. Rethinking the continuum of preparation and professional development for secondary science educators. 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). Studies in Science Education, 14, 33-62. Loucks-Horsley, S., Love, N., Stiles, K.E., Mundry, S., and Hewson, P.W. Can schools narrow the black-white test score gap? Further research is needed to evaluate these and other efforts to link scientists with K-12 education. In doing so, they showed teachers how laboratory experiences. The inequities in the availability of academically prepared teachers may pose a serious challenge to minority and poor students progress toward the. Science Education, 77(1), 25-46. Studies focusing specifically on science teacher quality and student achievement are somewhat more conclusive. Understanding cellular respiration: An analysis of conceptual change in college biology. 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). Research on the efficacy of strategies used for professional development related specifically to laboratory experiences, however, is not readily available. The actual crime scene processing takes place in one day and the entire project can take up to 7 depending on your schedule. Journal of Research in Science Teaching, 30, 919-934. In J.M. University researchers inchoate critiques of science teaching: Implications for the content of pre-service science teacher education. A study of a much smaller sample of teachers yielded similar findings (Catley, 2004). 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. For example, the teacher might use descriptive or qualitative language or images to convey concepts related to. Laboratories in science education: Understanding the history and nature of science. (1990). As Laboratory training is also frequently used to develop skills necessary for more advanced study or research. Available at: http://www.bayerus.com/msms/news/facts.cfm?mode=detailandid-survey04 [accessed Dec. 2004]. More than 90 percent of the class indicated that the experiment was highly effective in demonstrating the difficulty of scientific investigations and the possibility of failure in science (Glagovich and Swierczynski, 2004). Linn, M.C. 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). 4.8.

Active assessment for active learning. Summer research experiences that may enhance science teachers laboratory teaching need not take place in a laboratory facility. 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. Rethinking laboratories. Bell, P. (2004). Journal of Research in Science Teaching, 39(3), 205-236. In the Seattle program, teachers attend a 13-day summer workshop in which they work closely with each other, master teachers, and program staff to develop expertise in molecular biology. 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). 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. Available at: http://www.fhcrc.org/education/sep/ [accessed Feb. 2005]. Teachers lacking a science major may be less likely to engage students in any type of laboratory experience and may be less likely to provide more advanced laboratory experiences, such as those that engage the students in posing research questions, in formulating and revising scientific models, and in making scientific arguments. 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. (1990). 249-262). 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. 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. 9-13 Thus, medical laboratory professionals can be key members of the interprofessional health care team. 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.

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). 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. Haase, B.S. Playing this critical role requires that teachers know much more than how to set up equipment, carry out procedures, and manage students physical activities. The primary role of a teacher is to establish a learning environment where all students are able to learn and are motivated to learn, an environment that is both challenging and supportive: Establish a learning community consisting of the teacher and the students Harlen, W. (2000). Educational Evaluation and Policy Analysis, 24(2), 81-112. Forty-seven percent completed and returned the questionnaire. In addition, there is little research on whether use of block scheduling influences teachers instruction or enhances student learning. Drawing up suitable assessments and delivering helpful feedback to students, parents, and other teachers. Portsmouth, NH: Heinemann. International Journal of Science Education 22(7), 665-701.

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. Mahwah, NJ: Lawrence Earlbaum. These professionals use specialized instrumentation and techniques to analyze patients' samples, such as blood, urine, body fluids and tissue, and stool. Establishing classroom, lab, and field trip rules and regulations and ensuring that . Washington, DC: Author. Providing more focused, effective, and sustained professional development activities for more science teachers requires not only substantial financial resources and knowledge of effective professional development approaches, but also a coherent, coordinated approach at the school and district level. In W. Fowler (Ed. or use these buttons to go back to the previous chapter or skip to the next one. Fraser and K.G. Ferguson, R.

Duration (total contact hours, span of time). School districts, teachers, and others may want to consider these examples, but further research is needed to determine their scope and effectiveness. 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). The California Institute of Technology has a program to help scientists and graduate students work with teachers in elementary school classrooms in the Pasadena school district.

It was implemented over four day-long Saturday sessions spread over a semester. (2004). Pedagogical content knowledge can help teachers and curriculum developers identify attainable science learning goals, an essential step toward designing laboratory experiences with clear learning goals in mind. Available at: http://www7.nationalacademies.org/bose/KTobin_71204_HSLabs_Mtg.pdf [accessed August 2005]. 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). When students have more freedom to pose questions or to identify and carry out procedures, they require greater guidance to ensure that their laboratory activities help them to master science subject matter and progress toward the other goals of laboratory experiences. A new wave of evidenceThe impact of school, family, and community connections in student achievement. Discovery learning and discovery teaching. 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. .

Volunteers receive training, a sourcebook of activities appropriate for middle school students, a kit of science materials, and a set of videotapes. Focusing laboratory experiences on clear learning goals requires that teachers understand assessment methods so they can measure and guide their students progress toward those goals. The extent of student learning in any educational environment depends largely on the effectiveness of the instructors. ReviewLiterature review: The role of the teacher in inquiry-based education. Available at: http://www7.nationalacademies.org/bose/March_29-30_2004_High_School_Labs_Meeting_Agenda.html [accessed Oct. 2005]. Those who understand: Knowledge growth in teaching. Mathematics and science teachers reported more frequently than other teachers that job dissatisfaction was the reason they left their jobs. 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. 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. This timely book investigates factors that influence a high school laboratory experience, looking closely at what currently takes place and what the goals of those experiences are and should be. One study indicated that significant change in teaching practice required about 80 hours of professional development (Supovitz and Turner, 2000). Evaluating the evidence on teacher certification: A rejoinder. The National Survey of Science and Mathematics Education: Trends from 1977 to 2000. Examining the effects of a highly rated curriculum unit on diverse students: Results from a planning grant. A survey of students, teachers, and volunteers yielded positive results. Sign up for email notifications and we'll let you know about new publications in your areas of interest when they're released. 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. Their previous, closely prescribed laboratory experiences had not helped them to understand that there are many different ways to effect a particular chemical transformation. 1 Introduction, History, and Definition of Laboratories, 3 Laboratory Experiences and Student Learning, 5 Teacher and School Readiness for Laboratory Experiences, 7 Laboratory Experiences for the 21st Century, APPENDIX A Agendas of Fact-Finding Meetings, APPENDIX B Biographical Sketches of Committee Members and Staff. They found a large number of preparations, tried each one out, and identified one method as most likely to succeed with the introductory students. Journal of College Science Teaching, 33(6). Some individual teachers told our committee that they did not have adequate preparation and cleanup time. Younger workers in a variety of occupations change jobs more frequently than their older counterparts (National Research Council, 1999). 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). In addition, few high school teachers have access to curricula that integrate laboratory experiences into the stream of instruction. Science teachers may be modeling instructional practices they themselves witnessed or experienced firsthand as students in college science classes. The role of the laboratory in science teaching: Neglected aspects of research. 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.

However, formulating such questions can be difficult (National Research Council, 2001a, 2001b). This earlier research indicated that, just as engaging students in laboratory experiences in isolation led to little or no increase in their understanding of the nature of science, engaging prospective or current science teachers in laboratory activities led to little or no increase in their understanding of the nature of science. Erroneous ideas about respiration: The teacher factor. Because many current science teachers have demographic backgrounds different from their students (Lee, 2002; Lynch, Kuipers, Pyke, and Szeze, in press), the ability to communicate across barriers of language and culture is. (1998). 99-138). (2004). 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. Zahopoulos, C. (2003). A research agenda. School administrators can take several approaches to providing time for this type of ongoing discussion and reflection that supports student learning during laboratory experiences. Olsen, T.P., Hewson, P.W., and Lyons, L. (1996). Educational Policy, 14(3), 331-356. (1995). ), Knowledge base for the beginning teacher. To date, over 400 RE-SEED volunteers have worked with schools in 10 states. 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).
