(1994). All of these factors indirectly affect the academic achievement of the students. Teachers may help children become more confident and proficient readers by breaking down the reading comprehension process into discrete subtasks and offering targeted teaching and feedback on each one. 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. Biology student teachers' ideas about purpose of laboratory work Implications of teachers beliefs about the nature of science: Comparisons of the beliefs of scientists, secondary science teachers, and elementary science teachers. PDF The role and purpose of practical work in the teaching and earning of The National Science Teachers Association takes a slightly different position, suggesting that administrators provide teachers with a competent paraprofessional. In addition, there is little research on whether use of block scheduling influences teachers instruction or enhances student learning. In L.P. Steffe and J. Gale (Eds. Forty-seven percent completed and returned the questionnaire. Abstract available at: http://epx.sagepub.com/cgi/content/abstract/17/5/613 [accessed May 2005]. Discovery learning and discovery teaching. 357-382). 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). ERIC - ED213672 - Laboratory Schools: Updated or Outdated., 1981 Teachers require deep conceptual knowledge of a science discipline not only to lead laboratory experiences that are designed according to the research,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). Primary science: Taking the plunge. They also modeled longer postlaboratory activities focused on using student data and observations as the engine for further instruction. Teacher and School Readiness for Laboratory Experiences (2001). Second group of factors are the environmental factors. Schulze (Eds. 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. In many cases teachers ranked in-service training as their least effective source of learning (Windschitl, 2004, p. 16; emphasis in original). (2002). Ann Arbor, MI 48109-2218, Strategies for Effective Teaching in the Laboratory Class, 2021Regents of the University of Michigan. The extent of student learning in any educational environment depends largely on the effectiveness of the instructors. teacher is teaching both chemistry and physics, requiring more preparation time (American Association of Physics Teachers, 2002). Henderson, A.T., and Mapp, K.L. Teachers design and carry out an open-ended field research project, of their own choosing. 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. Educational Evaluation and Policy Analysis, 23(1), 79-86. 153-186). Time constraints can also discourage teachers from the challenges of setting up and testing laboratory equipment and materials. 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). Further research is needed to examine the scope and effectiveness of the many individual programs and initiatives. Washington, DC: Author. Data from the 2000 National Survey of Science and Mathematics Education. Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. Laboratory Instructors are responsible for maintaining the routine preventative maintenance of all laboratory equipment. Examining the effects of a highly rated curriculum unit on diverse students: Results from a planning grant. The investigators found that professional development focused. 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. Education Economics, 7(3), 199-208. Gitomer, D.H., and Duschl, R.A. (1998). Goldhaber, D.D. Shared teacher planning time may be a critical support for improved laboratory teaching, because of the unique nature of laboratory education. 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. As a GSI you are transitioning from a student to an instructor, from someone whose responsibility was to learn in the lab class to someone who now helps others learn in the lab class. London, England: Kluwer Academic. Classroom assessment and the national science education standards. 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). You will need to develop your own teaching style, your own way of interacting with students, and your own set of actions that determine the learning atmosphere of the classroom. Educational Policy, 17(5), 613-649. Respecting childrens own ideas. London, England: Routledge. Because efforts to improve teachers ability to lead improved laboratory experiences are strongly influenced by the organization and administration of their schools, the following section addresses this larger context. 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 They need to carefully consider written work and what they observe while students engage in projects and investigations. (ED 409-634.) The role of the laboratory in science learning. Davis, and P. Bell (Eds. 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. A study of a much smaller sample of teachers yielded similar findings (Catley, 2004). A series of studies conducted over the past several decades has shown that teachers are one of the most important factors influencing students. 791-810). Constructivist approaches to science teaching. 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. In D.G. American Educational Research Journal 35(3), 477-496. Darling-Hammond, L., Berry, B., and Thoreson, A. 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. Baumgartner, E. (2004). Millar, R. (2004). 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). He enrolled at the University of the Free State in 1980 and obtained a BSc degree in Mathematics and Physics, as well as a Higher Education Diploma. 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. 99-138). 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. Why staying ahead one chapter doesnt really work: Subject-specific pedagogy. The organization and structure of most high schools impede teachers and administrators ongoing learning about science instruction and the implementation of quality laboratory experiences. 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. Teacher and classroom context effects on student achievement: Implications for teacher evaluation. of habitual errors aids pupil in understanding nature of satisfactory performance Managing Practice Effectively laboratory and clinical experiences not merely repeating same exercise essential to goal attainment in psycho-motor and cognitive areas a teacher can manipulate whole-part approaches Helping Students . 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. Hillsdale, NJ: Lawrence Erlbaum. Among teachers who acted as heads of science departments, 21 percent indicated that the lack of opportunities for teachers to share ideas was a serious problem for science instruction (Smith et al., 2002). [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. PDF The Role of Language Laboratory in English Language Learning Settings - ed However, the undergraduate education of future science teachers does not currently prepare them for effective laboratory teaching. 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. (2004). A survey of students, teachers, and volunteers yielded positive results. 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). Anderson, C., Sheldon, T., and Dubay, J. Prospective and practicing secondary school science teachers knowledge and beliefs about the philosophy of science. DeSimone and others conducted a three-year longitudinal study of professional development in science and mathematics provided by school districts. Bruner, J.

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. 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. Laboratory Learning: An Inservice Institute. 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. Gamoran, A., Anderson, C.W., Quiroz, P.A., Seceda, W.G., Williams, T., and Ashmann, S. (2003). Tobin, K.G. Journal of Research in Science Teaching, 31, 621-637. 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. 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). Atkin and J.E. (1990). Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). However, experts do not agree on which aspects of teacher qualitysuch as having an academic major in the subject taught, holding a state teaching certificate, having a certain number of years of teaching experience, or other unknown factorscontribute to their students academic achievement (Darling-Hammond, Berry, and Thoreson, 2001; Goldhaber and Brewer, 2001). Washington, DC: Author. The proper performance of these duties requires the undivided attention of the teaching assistant during each laboratory period. Lab Safety Teacher Responsibilities - Carolina Knowledge Center DeSimone, L.M., Porter, A.S., Garet, M.S., Yoon, K.S., and Birman, B. Science teachers may be modeling instructional practices they themselves witnessed or experienced firsthand as students in college science classes. to the content of textbooks, to visual aids, or to laboratory equipment. Chapel Hill, NC: Horizon Research. New York: Teachers College Press. 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. The paraprofessional would help with setup, cleanup, community contacts, searching for resources, and other types of support (National Science Teachers Association, 1990). Smith, S. (2004). Learning in the laboratory: Some thoughts from the literature. 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). Further research is needed to inform design of professional development that can effectively support improvements in teachers laboratory instruction. McComs (Eds. Chapel Hill, NC : Horizon Research. 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. People working in the clinical laboratory are responsible for conducting tests that provide crucial information for detecting, diagnosing, treating, and monitoring disease. on specific instructional practices increased teachers use of these practices in the classroom. At the same time, teachers must address logistical and practical concerns, such as obtaining and storing supplies and maintaining laboratory safety. In another approach, schools can schedule science classes for double periods to allow more time for both carrying out investigations and reflecting on the meaning of those investigations. They should advise teachers where any concerns arise regarding safety, scheduling or resourcing of Available at: http://www7.nationalacademies.org/bose/KTobin_71204_HSLabs_Mtg.pdf [accessed August 2005]. Do higher salaries buy better teachers? Welcome to the Science Education Partnership. Guiding students to formulate their own research questions and design appropriate investigations requires sophisticated knowledge in all four of the domains we have identified. 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. The Role of the Laboratory in Chemistry Teaching and Learning In addition, few high school teachers have access to curricula that integrate laboratory experiences into the stream of instruction. Educational Researcher, 15, 4-14. The arts and science as preparation for teaching. Literature review: The role of the teacher in inquiry-based education. These limits, in turn, could contribute to lower science achievement, especially among poor and minority students. Professional development opportunities for science teachers are limited in quality, availability, and scope and place little emphasis on laboratory instruction. Once on the job, science teachers have few opportunities to improve their laboratory teaching. Currently, teachers rarely provide opportunities for students to participate in formulating questions to be addressed in the laboratory. ), Development in school finance, 1996. Haase, B.S. Prepare lab apparatus and equipment. What changes need to be made to improve laboratory experiences for high school students? The Role of the Laboratory in Science Teaching: Neglected Aspects of New York: City College Workshop Center. 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). It was also clear that teachers enhanced their understanding of science subject matter specific to the lab they experienced. ), How students learn: Reforming schools through learner-centered education (pp. Pomeroy, D. (1993). The teachers skills in posing questions and leading discussions affect students ability to build meaning from their laboratory experiences. In a study of 100 preservice science teachers, only 20 percent reported having laboratory experiences that gave them opportunities to ask their own questions and to design their own science investigations (Windschitl, 2004). Hudson, S.B., McMahon, K.C., and Overstreet, C.M. 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. These professionals use specialized instrumentation and techniques to analyze patients' samples, such as blood, urine, body fluids and tissue, and stool. 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).
