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. ), Proceedings of the Conference on K-12 Outreach from University Science Departments. 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. Introduction The laboratory in the school has been defined by several authors in different ways. 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. (1994). National Research Council. 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). Teachers play a critical role in leading laboratory experiences in ways that support student learning. Mahwah, NJ: Lawrence Earlbaum. 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. 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. The functions of the laboratory teaching assistant are to provide instruction, supervision, and assistance, as required, to the students in his/her section. Education Next, 2(1), 50-55. In C. Jencks and M. Phillips (Eds. (2000). Is laboratory-based instruction in beginning college-level chemistry worth the effort and expense? Professional Development Partnerships with the Scientific Community. Culturally adaptive teaching and learning science in labs. 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). Catley, K. (2004). (1994). Knowledge of childrens mental and emotional development, of teaching methods, and how best to communicate with children of different ages is essential for teachers to help students build meaning based on their laboratory experiences. They found a large number of preparations, tried each one out, and identified one method as most likely to succeed with the introductory students. 100 Washtenaw Ave. 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. National Research Council. 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. Teachers require deep conceptual knowledge of a science discipline not only to lead laboratory experiences that are designed according to the research, but also to lead a full range of laboratory experiences reflecting the range of activities of scientists (see Chapter 1).

The Integral Role of Laboratory Investigations in Science - NSTA Few professional development programs for science teachers emphasize laboratory instruction. 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. 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). 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). Davis, and P. Bell (Eds. U.S. Department of Education. Available at: http://www.horizon-research.com/reports/2002/2000survey/trends.php [accessed May 2005]. Erroneous ideas about respiration: The teacher factor. ), International handbook of science education (pp. The role of the laboratory in science teaching: Neglected aspects of research. They reported that the chief function of their school was instruction, followed, in order of emphasis, by preservice teacher education, research, and inservice teacher education. 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
Biology student teachers' ideas about purpose of laboratory work PDF Classroom Teachers' Opinions on Science Laboratory Practices Teachers draw on all of the types of knowledge listed abovecontent knowledge, pedagogical content knowledge, general pedagogical knowledge, and knowledge of assessmentin their daily work of planning and leading instruction. The committee identified a limited portfolio of examples of promising approaches to professional development that may support teachers in leading laboratory experiences 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. 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. Second group of factors are the environmental factors. Educational Researcher, 15, 4-14. 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. Fraser and K.G. Participation of groups of teachers from the same school, department, or grade. National Center for Education Statistics. National Research Council. 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. Participant teachers were also interviewed. Wojnowski, and S.K. (2004). Supovitz, J.A., and Turner, H.M. (2000). Washington, DC: Author. (2004). People working in the clinical laboratory are responsible for conducting tests that provide crucial information for detecting, diagnosing, treating, and monitoring disease.

However, a review of the literature five years later revealed no widespread efforts to improve laboratory education for either preservice or in-service teachers (McComas and Colburn, 1995). In W. Fowler (Ed. 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. The teachers skills in posing questions and leading discussions affect students ability to build meaning from their laboratory experiences. 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. (1986). (2004). Lunetta, V.N. 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. McComs (Eds. Volkmann, M., and Abell, S. (2003). New York: Teachers College Press. Linn, E.A. Not a MyNAP member yet? As we have discussed, teachers face an ongoing tension between allowing students greater autonomy in the laboratory and guiding them toward accepted scientific knowledge. Washington, DC: Brookings Institution. 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). About this Course. Schwartz, R., and Lederman, N. (2002). They must consider how to clearly communicate the learning goals of the laboratory experience to their students. Harlen, W.

The changing nature of work: Implications for occupational analysis. Associations of science teachers have taken differing positions on how administrators can best support teachers in preparing for and cleaning up after laboratory experiences. However, the undergraduate education of future science teachers does not currently prepare them for effective laboratory teaching.

Laboratory Experiences and Student Learning - The National Academies Press Journal of Science Teacher Education, 6(2), 120-124. Another analysis of the data from the National Center for Education Statistics found that students in high schools with higher concentrations of minority students and poor students were more likely than students in other high schools to be taught science by a teacher without a major or minor in the subject being taught (U.S. Department of Education, 2004). It means focusing the students own questions. 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).

II. Responsibilities and Duties of Teaching Assistants in Chemistry (1997). We do not yet know how best to develop the knowledge and skills that teachers require to lead laboratory experiences that help students master science subject matter, develop scientific reasoning skills, and attain the other goals of laboratory education. Do you want to take a quick tour of the OpenBook's features? The Biological Sciences Curriculum Study. Other studies have also found that most teachers do not experience sustained professional development and that they view it as ineffective (Windschitl, 2004). 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). 13-Week Science Methodology Course. Bayer Corporation. For example, the U.S. Department of Energy (DOE) launched its Laboratory Science Teacher Professional Development Program in 2004. ), Internet environments for science education. Most states do not regulate the quality and content of professional development required for renewal of teaching certificates (Hirsch, Koppich, and Knapp, 2001). 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.
Literature review: The role of the teacher in inquiry-based education 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). ASCP understands your role in the medical laboratory and has developed cost effective learning products, tools to manage your re-certification, and opportunities for you to grow as a leader in the laboratory. Reynolds (Ed. One study found that, when laboratories were easily accessible, 14- and 15-year-old students who used the facilities during their free time reported increased interest in academics and took advanced science courses (Henderson and Mapp, 2002). Project ICAN: Inquiry, Context, and Nature of Science. Arlington, VA: National Science Foundation.
What Are the Duties of a Student Lab Assistant? | Work - Chron Evaluating the evidence on teacher certification: A rejoinder. Guiding students through the complexity and ambiguity of empirical. Coherence (consistency with teachers goals, state standards, and assessments). Time constraints can also discourage teachers from the challenges of setting up and testing laboratory equipment and materials. 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. 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). 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. It is unclear whether these and other ad hoc efforts to provide summer research experiences reach the majority of high school science teachers. 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). ), Faculty development for improving teacher preparation (pp. [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. As is known, it is suggested that closedended - experiments cannot contribute much to meaningful the learning of students [13].
The Role of the Laboratory in Chemistry Teaching and Learning Science Education, 75, 121-133.
The Role of Laboratory in Science Teaching | NARST A focus on deepening teachers knowledge of science or mathematics. Requirements for professional development of in-service science teachers differ widely from state to state. Goldhaber, D.D., and Brewer, D.J. It may be useful, however, to begin . (1990). To determine the current role of laboratory schools in the United States, the 123 existing laboratory schools were surveyed. Note: The suggestions below were generated by a group of U-M GSIs based on their experiences teaching in a physics lab course. Laboratory Instructors are responsible for maintaining the routine preventative maintenance of all laboratory equipment. Once on the job, science teachers have few opportunities to improve their laboratory teaching. We then go on to describe approaches to supporting teachers and improving their capacity to lead laboratory experiences through improvements in professional development and use of time. Jump up to the previous page or down to the next one. For example, among high school teachers who had participated in professional development aimed at learning to use inquiry-oriented teaching strategies, 25 percent indicated that this professional development had little or no impact, and 48 percent reported that the professional development merely confirmed what they were already doing. 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. They should advise teachers where any concerns arise regarding safety, scheduling or resourcing of Designing computer learning environments for engineering and computer science: The scaffolded knowledge integration framework. ReviewLiterature review: The role of the teacher in inquiry-based education. 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.
PDF Laboratory Practices of Beginning Secondary Science Teachers: A - ed It means figuring out what students comprehend by listening to them during their discussions about science. What does research tell us about learning in high school science labs? Washington, DC: National Academy Press. The group employs a variety of long-term strategies, such as engaging teachers in curriculum development and adaptation, action research, and providing on-site support by lead teachers (Linn, 1997; Lederman, 2004). However, several types of inflexible scheduling may discourage effective laboratory experiences, including (a) limits on teacher planning time, (b) limits on teacher setup and cleanup time, and (c) limits on time for laboratory experiences. (1999). 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. The. A three-way error components analysis of educational productivity. Case studies of laboratory teaching show that laboratory activities designed to verify known scientific concepts or laws may not always go forward as planned (Olsen et al., 1996). Key words: Laboratory, chemistry, teaching, achievement, students. (2002). These might include websites, instructional materials, readings, or other resources to use with students. Washington, DC: National Academy Press. In D.G. National Center for Family and Community Connections with Schools. Washington, DC: National Academy Press. 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. Sanders, M. (1993). Research conducted in teacher education programs provides some evidence of the quality of preservice science education (Windschitl, 2004). Teacher awareness of students science needs and capabilities may be enhanced through ongoing formative assessment. 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. Using questioning to guide student thinking. Methods of assessing student learning in laboratory activities include systematically observing and evaluating students performance in specific laboratory tasks and longer term laboratory investigations. DeSimone, L.M., Garet, M., Birman, B., Porter, A., and Yoon, K. (2003). At Vanderbilt University, Catley conducts a summer-long course on research in organismal biology. Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). (1996). Williams, M., Linn, M.C., Ammon, P., and Gearhart, M. (2004). (2002). This chapter describes some of the factors contributing to the weakness of current laboratory experiences. 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. Cumulative and residual effects of teachers on future student academic achievement. In doing so, they showed teachers how laboratory experiences. Researchers generally agree that the teachers academic preparation in science has a positive influence on students science achievement (U.S. Department of Education, 2000; National Research Council, 2001a). Tushnet, N.C., Millsap, M.A., Noraini, A., Brigham, N., Cooley, E., Elliott, J., Johnston, K., Martinez, A., Nierenberg, M., and Rosenblum, S. (2000). Baumgartner, E. (2004). 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. Seattle: University of Washington, Center for the Study of Teaching and Policy. 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. Drawing up suitable assessments and delivering helpful feedback to students, parents, and other teachers. ), How students learn: Reforming schools through learner-centered education (pp. Thousand Oaks, CA: Corwin Press. McDiarmid, G.W. Examining the effects of a highly rated curriculum unit on diverse students: Results from a planning grant. Other duties include reinforcing laboratory housekeeping and safety protocol, coordinating with other engineering departments, and receiving, installing, and maintaining laboratory supplies and equipment. Specifically, it challenges the assumption that having a college degree in science, by itself, is sufficient to teach high school science. All of these factors indirectly affect the academic achievement of the students. Educational Policy, 17(5), 613-649. At the same time, teachers must address logistical and practical concerns, such as obtaining and storing supplies and maintaining laboratory safety. Laboratory Demonstrations: Do start class by demonstrating key techniques or equipment operation or describing the location and handling of special materials. Songer, C., and Mintzes, J. Deep disciplinary expertise is necessary to help students learn to use laboratory tools and procedures and to make observations and gather data. Paper presented at the National Association for Research in Science Teaching meeting, March 23, Chicago, IL. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. The institute included a blend of modeling, small group work, cooperative learning activities, and theoretical and research-based suggestions (p. 122). (2003). Shared teacher planning time may be a critical support for improved laboratory teaching, because of the unique nature of laboratory education. The Role of the Teacher in . Although the time frame of the study prevented analysis of whether the teacher communities were sustained over time, the results suggest that school districts can use focused professional development as a way to create strong teaching communities with the potential to support continued improvement in laboratory teaching and learning. Science Education, 77(3), 301-317. One theme that emerges from such research is that the content knowledge gained from undergraduate work is often superficial and not well integrated. Further research is needed to examine the scope and effectiveness of the many individual programs and initiatives. Learning to teach inquiry science in a technology-based environment: A case study. Available at: http://www7.nationalacademies.org/bose/March_29-30_2004_High_School_Labs_Meeting_Agenda.html [accessed Oct. 2005]. 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. 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). can be sequenced into a flow of science instruction in order to integrate student learning of science content and science processes. Hilosky, A., Sutman, F., and Schmuckler, J. Welcome to the Science Education Partnership. Slotta, J.D. School administrators can take several approaches to providing time for this type of ongoing discussion and reflection that supports student learning during laboratory experiences. Gamoran, A., Anderson, C.W., Quiroz, P.A., Seceda, W.G., Williams, T., and Ashmann, S. (2003). International Journal of Science Education, 18(7), 775-790. Journal of Science Education and Technology, 4(2), 103-126. 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.
