role of teacher in laboratory

Paper prepared for the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. Teachers and teacher aides should lead by example and wear personal protective equipment (PPE); follow and enforce safety rules, procedures, and practices; and demonstrate safety behavior to promote a culture of safety. Among these factors, curriculum has a strong influence on teaching strategies (Weiss, Pasley, Smith, Banilower, and Heck, 2003). (1997). It may be useful, however, to begin . About this Course. Most states do not regulate the quality and content of professional development required for renewal of teaching certificates (Hirsch, Koppich, and Knapp, 2001). 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). Linn, M.C. ), Internet environments for science education. Hein, G.E., and Price, S. (1994). 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. McComas and Colburn (1995) established an inservice program called Laboratory Learning: An Inservice Institute, which incorporated some of the design elements that support student learning in laboratory experiences. Why staying ahead one chapter doesnt really work: Subject-specific pedagogy. Elementary School Journal, 97(4), 401-417. What changes need to be made to improve laboratory experiences for high school students? Those who understand: Knowledge growth in teaching. Laboratory activities have long had a distinct and central role in the science curriculum as a means of making sense of the natural world. Laboratory experiments 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 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. How should student learning in laboratory experiences be assessed? Leading laboratory experiences is a demanding task requiring teachers to have sophisticated knowledge of science content and process, how students learn science, assessment of students learning, and how to design instruction to support the multiple goals of science education. 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. McComs (Eds. Before its too late: A report to the nation from the national commission on mathematics and science teaching for the 21st century. And, among teachers who left because of job dissatisfaction, mathematics and science teachers reported more frequently than other teachers that they left because of poor administrative support (Ingersoll, 2003, p. 7). 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. Rethinking laboratories. Further research is needed to evaluate these and other efforts to link scientists with K-12 education. 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).

The role of the laboratory in science teaching: Neglected aspects of research. 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. 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. workincluding verification workrequires deep knowledge of the specific science concepts and science processes involved in such work (Millar, 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. 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 . One theme that emerges from such research is that the content knowledge gained from undergraduate work is often superficial and not well integrated. (2003). 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. Cambridge, MA: Harvard University Press. McDiarmid, G.S., Ball, D.L., and Anderson, C.W. Classroom assessment and the national science education standards. Guiding students to formulate their own research questions and design appropriate investigations requires sophisticated knowledge in all four of the domains we have identified. In M.D. It is unclear whether these and other ad hoc efforts to provide summer research experiences reach the majority of high school science teachers. or use these buttons to go back to the previous chapter or skip to the next one.

Specifically, it challenges the assumption that having a college degree in science, by itself, is sufficient to teach high school science. In response to surveys conducted in the mid-1990s, teachers indicated that, among the reasons they left their positionsincluding retirement, layoffs, and family reasonsdissatisfaction was one of the most important. instructors and laboratory assistants working in school or college settings in vocational . Further research is needed to inform design of professional development that can effectively support improvements in teachers laboratory instruction.

Learning to teach inquiry science in a technology-based environment: A case study. Teacher participants at the institute experienced firsthand learning as students in several laboratory sessions led by high school instructors who were regarded as master laboratory teachers. The role of the laboratory in science learning. In addition, some researchers argue that, although professional development expends resources (time, money, supplies), it also creates new human and social resources (Gamoran et al., 2003, p. 28). In D.G. This is knowledge drawn from learning theory and research that helps to explain how students develop understanding of scientific ideas. Note: The suggestions below were generated by a group of U-M GSIs based on their experiences teaching in a physics lab course. (2004). 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 Providing Expert Assistance to Schools and Teachers. International Journal of Science Education, 18(7), 775-790. The National Research Council (NRC) Committee on Science and Mathematics Teacher preparation stated that studies conducted over the past quarter century increasingly point to a strong correlation between student achievement in K-12 science and mathematics and the teaching quality and level of knowledge of K-12 teachers of science and mathematics (National Research Council, 2001a, p. 4). Meaning making in secondary science classrooms. Strong academic preparation is also essential in helping teachers develop the deep knowledge of science content and science processes needed to lead effective laboratory experiences. The investigators found that professional development focused.

(2001). Knowledge of students cultures and languages and the ability to communicate across cultures are necessary to carry out laboratory experiences that build on diverse students sense of wonder and engage them in science learning. 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. Learning in the laboratory: Some thoughts from the literature. Zip. Final report on the evaluation of the National Science Foundations Instructional Materials Development Program. They appeared to have little understanding of the field writ large. 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). 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.

Typically, states require only that teachers obtain post-baccalaureate credits within a certain period of time after being hired and then earn additional credits every few years thereafter. (2002). The Higher Education Chemistry (RSC), 5 (2), 42-51. on specific instructional practices increased teachers use of these practices in the classroom. In the ICAN program, teachers participate in science internships with working scientists as one element in a larger program of instruction that includes an initial orientation and monthly workshops.

A Japanese high school language lab shows students' positions Goldhaber, D.D. These strategies included arranging seating to facilitate student discussion, requiring students to supply evidence to support their claims, encouraging students to explain concepts to one another, and having students work in cooperative groups. Implications of teachers beliefs about the nature of science: Comparisons of the beliefs of scientists, secondary science teachers, and elementary science teachers. 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. Teachers, Laboratory Attendants and Gardeners must be made to attend, at regular . Olsen, T.P., Hewson, P.W., and Lyons, L. (1996). National Science Teachers Association. 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).

This body of knowledge addressed the kind of laboratory instruction given to students, consideration of students with special needs, supportive teaching behaviors, models to engage students working in small groups, the sequencing of instruction, and modes of assessment (p. 121). They must consider how to clearly communicate the learning goals of the laboratory experience to their students. Washington, DC: American Psychological Association. Science teachers behavior in the classroom is influenced by the science curriculum, educational standards, and other factors, such as time constraints and the availability of facilities and supplies. These workshops include microteaching (peer presentation) sessions. Teacher and classroom context effects on student achievement: Implications for teacher evaluation. In doing so, they showed teachers how laboratory experiences. 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. This is a culminating project for a Forensics course or unit. (2002). National Research Council. It was also clear that teachers enhanced their understanding of science subject matter specific to the lab they experienced. (1999). Hilosky, A., Sutman, F., and Schmuckler, J. 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). Associations of science teachers have taken differing positions on how administrators can best support teachers in preparing for and cleaning up after laboratory experiences. Block scheduling is one approach schools have used to provide longer periods of time for laboratory activities and discussion. Do you enjoy reading reports from the Academies online for free? Hofstein, A., and Lunetta, V.N. (1994). In addition to the many programs to increase teachers knowledge and abilities discussed above, the scientific community sometimes engages scientists to work directly with students. Education Economics, 7(3), 199-208. However, the students were surprised that methods taken from the literature did not always work. 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. 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.

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. 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.

Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. 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. The final section concludes that there are many barriers to improving laboratory teaching and learning in the current school environment. Teacher awareness of students science needs and capabilities may be enhanced through ongoing formative assessment. This chapter describes some of the factors contributing to the weakness of current laboratory experiences. 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). Tushnet, N.C., Millsap, M.A., Noraini, A., Brigham, N., Cooley, E., Elliott, J., Johnston, K., Martinez, A., Nierenberg, M., and Rosenblum, S. (2000). 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. In addition to science content knowledge and pedagogical content knowledge, teachers also need general pedagogical knowledge in order to moderate ongoing discussion and reflection on laboratory activities, and supervise group work.

Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. 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. 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. They need to carefully consider written work and what they observe while students engage in projects and investigations.

Duration (total contact hours, span of time). New York: Teachers College Press. The American Association of Physics Teachers (AAPT) suggests that physics teachers should be required to teach no more than 275 instructional minutes per day. To determine the current role of laboratory schools in the United States, the 123 existing laboratory schools were surveyed. 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). 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.

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. 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.
