Journal of Research in Science Teaching, 30, 919-934. In contrast to these short, ineffective approaches, consensus is growing in the research about key features of high-quality professional development for mathematics and science teachers (DeSimone, Porter, Garet, Yoon, and Birman, 2002; DeSimone et al., 2003, p. 10): New forms of professional development (i.e., study group, teacher network, mentoring, or task force, internship, or individual research project with a scientist) in contrast to the traditional workshop or conference. Paper presented at the annual meeting of the National Association for Research in Science Teaching, April, St. Louis, MO. Austin, TX: Southwest Educational Development Laboratory. (1998). Journal of Science Education and Technology, 4(2), 103-126. Guiding students to formulate their own research questions and design appropriate investigations requires sophisticated knowledge in all four of the domains we have identified. Respecting childrens own ideas. Currently, teachers rarely provide opportunities for students to participate in formulating questions to be addressed in the laboratory. Teachers play a critical role in leading laboratory experiences in ways that support student learning. or use these buttons to go back to the previous chapter or skip to the next one. Supporting classroom discussions may be particularly challenging for teachers who work with a very diverse student population in a single classroom, or those who have a different cultural background from their students (see Tobin, 2004). In doing so, they showed teachers how laboratory experiences. Available at: http://www7.nationalacademies.org/bose/June_3-4_2004_High_School_Labs_Meeting_Agenda.html [accessed May 2005].

Studies focusing specifically on science teacher quality and student achievement are somewhat more conclusive. Tobin, K.G. One theme that emerges from such research is that the content knowledge gained from undergraduate work is often superficial and not well integrated. Journal of Science Education and Technology, 13(2), 189-206. Since the 19th century, when schools began to teach science systematically, the laboratory has become a distinctive feature of chemistry learning. Darling-Hammond, L., Berry, B., and Thoreson, A. You choose your level of involvement based on your needs. Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). 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.

Professional development and preservice programs that combined laboratory experiences with instruction about the key concepts of the nature of science and engaged teachers in reflecting on their experiences in light of those concepts were more successful in developing improved understanding (Khalic and Lederman, 2000). In this program, faculty modeled lower-level inquiry-oriented instruction focused on short laboratory sessions with limited lecturing and no definitions of terms.

You're looking at OpenBook, NAP.edu's online reading room since 1999. Some research indicates that teachers do not respond to sustained professional development by taking their new knowledge and skills to other schools, but rather by staying and creating new benefits where they are. Science Teacher (October), 40-43. 357-382). Zip. However, many high school teachers currently lack strong academic preparation in a science discipline. 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. Raleigh: Science House, North Carolina State University. Laboratory teaching assumes that first-hand experience in observation and manipulation of the materials of science is superior to other methods of developing understanding and appreciation. Teachers also need to know how to judge the quality of students oral presentations. (2002). Gamoran and others studied six sites where teachers and educational researchers collaborated to reform science and mathematics teaching, focusing on teaching for understanding. Pomeroy, D. (1993). (2003). All of these factors indirectly affect the academic achievement of the students. Effects of professional development on teachers instruction: Results from a three-year longitudinal study. Data from the National Center for Education Statistics (2004) show variation in teacher qualifications from one science discipline to another. Primary science: Taking the plunge. Collaborator. The Fermi National Accelerator Laboratory has provided professional development programs for science teachers for several years (Javonovic and King, 1998). 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). Science Education, 85(3), 263-278. (1994). Science Education, 88, 28-54. 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.

Science educators, school administrators, policy makers, and parents will all benefit from a better understanding of the need for laboratory experiences to be an integral part of the science curriculumand how that can be accomplished. Active learning opportunities focused on analysis of teaching and learning. Science Educator, 12(1), 1-9. Most current professional development for science teachers, such as the activities that had little impact on the teaching strategies among teachers responding to the 2000 survey, is ad hoc. 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. 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. Show this book's table of contents, where you can jump to any chapter by name. To succeed at it and ask the types of higher level and cognitively based questions that appear to support student learning, teachers must have considerable science content knowledge and science teaching experience (McDiarmid, Ball, and Anderson, 1989; Chaney, 1995; Sanders and Rivers, 1996; Hammer, 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). As is known, it is suggested that closedended - experiments cannot contribute much to meaningful the learning of students [13]. Priestley, W., Priestley, H., and Schmuckler, J.

Even teachers who have majored in science may be limited in their ability to lead effective laboratory experiences, because their undergraduate science preparation provided only weak knowledge of science content and included only weak laboratory experiences. (1989). Drawing up suitable assessments and delivering helpful feedback to students, parents, and other teachers. When one college physics professor taught a high school physics class, he struggled with uncertainty about how to respond to students ideas about the phenomena they encountered, particularly when their findings contradicted accepted scientific principles (Hammer, 1997).

Only 11 percent of responding teachers indicated that science teachers in their school regularly observed other science teachers. They also face uncertainty about how many variables students should struggle with and how much to narrow the context and procedures of the investigation. 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. Anderson, C., Sheldon, T., and Dubay, J. Clearly, their preservice experiences do not provide the skills and knowledge needed to select and effectively carry out laboratory experiences that are appropriate for reaching specific science learning goals for a given group of students. A professor engaged upper level chemistry majors in trying to create a foolproof laboratory activity to illustrate the chemistry of amines for introductory students. What types of knowledge do teachers use to engage learners in doing science? Younger workers in a variety of occupations change jobs more frequently than their older counterparts (National Research Council, 1999). However, their study was criticized for being conducted in laboratory environment (Taylor, Ntoumanis, . To lead effective laboratory experiences, science teachers should know how to use data from all of these assessment methods in order to reflect on student progress and make informed decisions about which laboratory activities and teaching approaches to change, retain, or discard (National Research Council, 2001b; Volkman and Abell, 2003). What changes need to be made to improve laboratory experiences for high school students? Do you want to take a quick tour of the OpenBook's features? 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). During the school year, teachers may access kits of materials supporting laboratory experiences that use biomedical research tools. Lee and Fradd (1998) and others observe that some scientific values and attitudes are found in most cultures (e.g., wonder, interest, diligence, persistence, imagination, respect toward nature); others are more characteristic of Western science. Science teachers may be modeling instructional practices they themselves witnessed or experienced firsthand as students in college science classes. The investigators found that professional development focused. The Biological Sciences Curriculum Study. One study found that schools that provide more support to new teachers, including such professional development activities as induction and mentoring, have lower turnover rates (Ingersoll, 2003, p. 8). They lock up all the reagents and unplug all electrical equipment to minimize the chances of accidents and fires. Coherence (consistency with teachers goals, state standards, and assessments). 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). Sutman, F.X., Schmuckler, J.S., Hilosky, A.B., Priestly, H.S., and Priestly, W.J. 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 professional development institute also incorporated ongoing opportunities for discussion and reflection. Shared teacher planning time may be a critical support for improved laboratory teaching, because of the unique nature of laboratory education. The teachers skills in posing questions and leading discussions also help students to effectively and accurately communicate their laboratory activities and the science sense they make from them, using appropriate language, scientific knowledge, mathematics, and other intellectual modes of communication associated with a particular science discipline. A series of studies conducted over the past several decades has shown that teachers are one of the most important factors influencing students. (1997). At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory work, and the case for laboratory .

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). 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. Chemistry laboratories play an essential role in the education of undergraduate Science, Technology, Engineering, and Mathematics (STEM) and non-STEM students. Goldhaber, D.D., and Brewer, D.J.

Their previous, closely prescribed laboratory experiences had not helped them to understand that there are many different ways to effect a particular chemical transformation. The laboratory in science education: Foundations for the twenty-first century. Providing Expert Assistance to Schools and Teachers. A survey of students, teachers, and volunteers yielded positive results. 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. 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 reviewing the state of biology education in 1990, an NRC committee concluded that few teachers had the knowledge or skill to lead effective laboratory experiences and recommended that "major new programs should be developed for providing in-service education on laboratory activities" (National Research Council, 1990, p. 34). Does teacher certification matter? Journal of Chemical Education, 75(1), 100-104. Laboratories in science education: Understanding the history and nature of science. This chapter describes some of the factors contributing to the weakness of current laboratory experiences. 99-138). Assistants show the students how to handle chemical spills, dispose of broken glassware and get rid of non-hazardous and chemical waste . Haase, B.S. 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. Sanders, W.L., and Rivers, J.C. (1996). The elementary level science methods course: Breeding ground of an apprehension toward science? They found a large number of preparations, tried each one out, and identified one method as most likely to succeed with the introductory students. Teaching failure in the laboratory. A teachers academic science preparation appears to affect student science achievement generally. Professional development opportunities for science teachers are limited in quality, availability, and scope and place little emphasis on laboratory instruction. 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. Educational Researcher, 27, 12-21. 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. 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. Rockville, MD: Westat. Using questioning to guide student thinking. Laboratory learning: Addressing a neglected dimension of science teacher education. 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. Mahwah, NJ: Lawrence Earlbaum. (1997). Elementary School Journal, 97(4), 401-417. They are relevant for new lab instructors in a wide range of disciplines. 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. Educational Evaluation and Policy Analysis, 24(2), 81-112. 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. Goldhaber, D.D. Finally, an . Hanusek, E., Kain, J., and Rivkin, S. (1999). Generally, the body of research is weak, and the effects of teacher quality on student outcomes are small and specific to certain contexts. 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. International Journal of Science Education, 18(7), 775-790. Fraser and K.G. The Role of the Teacher in . Gess-Newsome, J., and Lederman, N. (1993). In 2000, according to a nationally representative survey of science teachers, most school administrators provided inadequate time for shared planning and reflection to improve instruction. 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 teaching: Neglected aspects of research. 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. In B.J. Marjolein Dobber a. , Rosanne Zwart b. , Marijn Tanis a b 1. , Bert van Oers a. In these discussions, the teacher helps students to resolve dissonances between the way they initially understood a phenomenon and the new evidence. Research on teachers using a science curriculum that integrates laboratory experiences into the stream of instruction indicates that repeated practice with such a curriculum, as well as time for collaboration and reflection with professional colleagues, leads teachers to shift from focusing on laboratory procedures to focusing on science learning goals (Williams, Linn, Ammon, and Gearheart, 2004). (1994). Gamoran and colleagues found that, although the educational researchers provided an infusion of expertise from outside each of the six school sites, the professional development created in collaboration with the local schools had its greatest impact in supporting local teachers in developing their own communities. Washington, DC: American Psychological Association. Teaching for understanding was defined as including a focus on student thinking, attention to powerful scientific ideas, and the development of equitable classroom learning communities. Goldhaber, D.D., and Brewer, D.J. Catley, K. (2004). 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). 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. 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. Teaching Assistant Responsibilities Arrive on time & remain in lab. Slotta, J.D. 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. The distinction between key ideas in teaching school physics and key ideas in the discipline of physics. 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. Songer, C., and Mintzes, J. 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. 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). Why staying ahead one chapter doesnt really work: Subject-specific pedagogy. At Vanderbilt University, Catley conducts a summer-long course on research in organismal biology.
