Thousand Oaks, CA: Corwin Press. Journal of Science Teacher Education, 6(2), 120-124. Pre-service education and in-service professional development for science teachers rarely address laboratory experiences and do not provide teachers with the knowledge and skills needed to lead laboratory experiences. Science Teacher Responsibilities: Designing, developing, and delivering quality lesson plans and curricula that adhere to national and school guidelines. 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. Atkin and J.E. Laboratory experiences as a part of most U.S. high school science curricula have been taken for granted for decades, but they have rarely been carefully examined. DeSimone, L.M., Porter, A.S., Garet, M.S., Yoon, K.S., and Birman, B. Teacher-Student Interaction . 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. 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. Olsen, T.P., Hewson, P.W., and Lyons, L. (1996). Available at: http://www7.nationalacademies.org/bose/KTobin_71204_HSLabs_Mtg.pdf [accessed August 2005]. Maienschein, J. Ingersoll, R. (2003). Shared teacher planning time may be a critical support for improved laboratory teaching, because of the unique nature of laboratory education. 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.

Designing professional development for teachers of science and mathematics. or use these buttons to go back to the previous chapter or skip to the next one. 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. Key words: Laboratory, chemistry, teaching, achievement, students. 1. (2002). London, England: Routledge. Ferguson, R.

How should student learning in laboratory experiences be assessed? (2004). They must guide and focus ongoing discussion and reflection with individuals, laboratory groups, and the entire class. Current professional development for science teachers is uneven in quantity and quality and places little emphasis on laboratory teaching. Periodic checks indicated that the science internship helped teachers improve their understanding of [the nature of science] and [science inquiry]. 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). U.S. Department of Energy. The mystery of good teaching: Surveying the evidence on student achievement and teachers characteristics. 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. Transforming teaching in math and science: How schools and districts can support change. (1997). 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). 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. Journal of College Science Teaching, 33(6). 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). Deep disciplinary expertise is necessary to help students learn to use laboratory tools and procedures and to make observations and gather data. Journal of Research in Science Teaching, 39(3), 205-236. 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).

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. Laboratory training is also frequently used to develop skills necessary for more advanced study or research. Fred Hutchinson Cancer Research Center. Its the nature of the beast: The influence of knowledge and intentions on learning and teaching nature of science. Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. To lead laboratory experiences that incorporate ongoing student discussion and reflection and that focus on clear, attainable learning goals, teachers require pedagogical content knowledge. Development of certified Medical Laboratory Scientists to assume a role as a member of the interprofessional health care team requires additional education to acquire advanced knowledge and skills. Science Teacher (October), 40-43. Block scheduling is one approach schools have used to provide longer periods of time for laboratory activities and discussion. The actual crime scene processing takes place in one day and the entire project can take up to 7 depending on your schedule. 61-74). Background: Journal of Research in Science Teaching, 20, 745-754.

Further research is needed to inform design of professional development that can effectively support improvements in teachers laboratory instruction. This is a culminating project for a Forensics course or unit. The main role of a teaching assistant is to provide support to the course instructor to ensure the effective delivery of the required materials and to foster a positive learning environment.

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. Further research is needed to inform design of laboratory-focused teacher professional development that can support teachers in improving laboratory instruction. New York: City College Workshop Center. The changing nature of work: Implications for occupational analysis. DeSimone, L.M., Garet, M., Birman, B., Porter, A., and Yoon, K. (2003). Teachers do not have sole responsibility for carrying out laboratory experiences that are designed with clear learning outcomes in mind, thoughtfully sequenced into the flow of classroom science instruction, integrating the learning of science content and process, and incorporating ongoing student reflection and discussion, as suggested by the research. Qualifications of the public school teacher workforce: Prevalence of out-of-field teaching 1987-88 to 1999-2000. Other studies report that undergraduate laboratory work consists primarily of verification activities, with few opportunities for ongoing discussion and reflection on how scientists evaluate new knowledge (e.g., Trumbull and Kerr, 1993, cited in Windschitl, 2004). Literature review: The role of the teacher in inquiry-based education. In W. Fowler (Ed. Anderson, C., Sheldon, T., and Dubay, J. Deng, Z. 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. However, it also reveals some gaps in the . Looking inside the classroom: A study of K-12 mathematics and science education in the United States. 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).

The paper recommend among others: . Scientific laboratories, college and university science departments, and science museums have launched efforts to support high school science teachers in improving laboratory teaching. in a limited range of laboratory experiences that do not follow the principles of instructional design identified in Chapter 3. Hillsdale, NJ: Lawrence Erlbaum. Why staying ahead one chapter doesnt really work: Subject-specific pedagogy. Properly designed laboratory investigations should: have a definite purpose that is communicated clearly to students; focus on the processes of science as a way to convey content; incorporate ongoing student reflection and discussion; and enable students to develop safe and conscientious lab habits and procedures (NRC 2006, p. 101-102). London, England: Kluwer Academic. They also modeled longer postlaboratory activities focused on using student data and observations as the engine for further instruction. The extent of student learning in any educational environment depends largely on the effectiveness of the instructors. Boys and girls in the performance-based classroom: Whos doing the performing?

After completion of the course, teachers classroom behaviors were videotaped and analyzed against traditional and reformed instructional strategies. It was implemented over four day-long Saturday sessions spread over a semester. Copyright 2023 National Academy of Sciences. (1990). 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). ), The black-white test score gap. Clark, R.L., Clough, M.P., and Berg, C.A. Teachers College Record, 105(3), 465-489. 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. Mahwah, NJ: Lawrence Earlbaum. The importance of pedagogical content knowledge challenges assumptions about what science teachers should know in order to help students attain the goals of laboratory experiences. Guiding students to formulate their own research questions and design appropriate investigations requires sophisticated knowledge in all four of the domains we have identified.

At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory work, and the case for laboratory . Enforcing laboratory rules . 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. 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.
