Arrangements must be made with Instructor to cover unavoidable absences or planned breaks. But those connections are not enough: science sense-making discourse must also help students to develop understanding of a given science concept and create links between theory and observable phenomena. Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. Welcome to the Science Education Partnership. 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). laboratory notebooks, essays, and portfolios (Hein and Price, 1994; Gitomer and Duschl, 1998; Harlen, 2000, 2001). 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 . 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). 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. The California Institute of Technology has a program to help scientists and graduate students work with teachers in elementary school classrooms in the Pasadena school district. 153-186). 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). when studying aspects of biology . Volkmann, M., and Abell, S. (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, 14(3), 331-356. 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. in a limited range of laboratory experiences that do not follow the principles of instructional design identified in Chapter 3. Laboratory Instructors are responsible for maintaining the routine preventative maintenance of all laboratory equipment. The American Association of Physics Teachers (AAPT) suggests that physics teachers should be required to teach no more than 275 instructional minutes per day. The study examined the relationship between professional development and teaching practice in terms of three specific instructional practices: (1) the use of technology, (2) the use of higher order instructional methods, and (3) the use of alternative assessment.

Promoting inquiry-based instructional practice: The longitudinal impact of professional development in the context of systemic reform. In 1999-2000, 39.4 percent of all physics teachers in public high schools had neither a major nor a minor in physics, 59.9 percent of all public high school geology teachers lacked a major or minor in geology, 35.7 percent of chemistry teachers lacked a major or minor in that field, and 21.7 percent of biology teachers had neither a major nor a minor in biology (National Center for Education Statistics, 2004). an increasingly important aspect of their general pedagogical knowledge. (1998). In L.P. Steffe and J. Gale (Eds. They must guide and focus ongoing discussion and reflection with individuals, laboratory groups, and the entire class. Assistants show the students how to handle chemical spills, dispose of broken glassware and get rid of non-hazardous and chemical waste . Understanding cellular respiration: An analysis of conceptual change in college biology. Linn describes aspects of the model as pragmatic principles of heat that are more accessible goals than the microscopic view of heat that is commonly taught (Linn, 1997, p. 410). 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. 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. (1995). He suggests that a high school physics teacher should know concepts or principles to emphasize when introducing high school students to a particular topic (p. 264). London, England: Kluwer Academic. Large majorities of students indicated that the program had increased their interest in science, while large majorities of teachers said they would recommend the program to other teachers and that the volunteers had had a beneficial effect on their science teaching. 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. New York: City College Workshop Center. (2002). The role of the laboratory in science teaching: Neglected aspects of research. Goldhaber, D.D., Brewer, D.J., and Anderson, D. (1999). Few professional development programs for science teachers emphasize laboratory instruction. Prospective and practicing secondary school science teachers knowledge and beliefs about the philosophy of science. In D.G. Harrison and Killion (2007) defined the roles of . Priestley, W., Priestley, H., and Schmuckler, J. 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). Harlen, W. (2000). Cobus van Breda was born and schooled in Windhoek, Namibia. The web-based inquiry science environment (WISE): Scaffolding knowledge integration in the science classroom. Internet environments for science education. To determine the current role of laboratory schools in the United States, the 123 existing laboratory schools were surveyed. Laboratory activities have long had a distinct and central role in the science curriculum as a means of making sense of the natural world. A supportive school administration could help teachers overcome their isolation and learn from each other by providing time and space to reflect on their laboratory teaching and on student learning in the company of colleagues (Gamoran, 2004). Lunetta, V.N. Second group of factors are the environmental factors. Formative assessment, that is, continually assessing student progress in order to guide further instruction, appears to enhance student attainment of the goals of laboratory education. Finally, adequate time is essential for student learning in laboratory experiences. Younger workers in a variety of occupations change jobs more frequently than their older counterparts (National Research Council, 1999). take place in a school laboratory, but could also occur in an out-of-school setting, such as the student's home or in the field (e.g. 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). It is unclear whether these and other ad hoc efforts to provide summer research experiences reach the majority of high school science teachers. (2000). Educational Evaluation and Policy Analysis, 24(2), 81-112. To be successful in leading students across the range of laboratory experiences we have described, teachers must choose laboratory experiences that are appropriate at any given time. Journal of Research in Science Teaching. Summer research experiences that may enhance science teachers laboratory teaching need not take place in a laboratory facility. Organizational conditions that support inquiry in high school science instruction. Zahopoulos, C. (2003). One study indicated that significant change in teaching practice required about 80 hours of professional development (Supovitz and Turner, 2000). In M.C. 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. Specifically, it challenges the assumption that having a college degree in science, by itself, is sufficient to teach high school science. Professional Development Partnerships with the Scientific Community. ), Internet environments for science education. Retired scientists and engineers: Providing in-classroom support to K-12 science teachers. Educational Evaluation and Policy Analysis, 23(1), 57-77. surveys defined poor administrative support as including a lack of recognition and support from administration and a lack of resources and material and equipment for the classroom. A science methodology course for middle and high school teachers offered experience in using the findings from laboratory investigations as the driving force for further instruction (Priestley, Priestly, and Schmuckler, 1997). Coherence (consistency with teachers goals, state standards, and assessments). The Role of the Teacher in . Finally, an . In a guided-inquiry laboratory (GIL), the teacher provides the students with a question, or set of questions, and the students design an experiment to address the question(s). Gamoran and others studied six sites where teachers and educational researchers collaborated to reform science and mathematics teaching, focusing on teaching for understanding. Students cannot be admitted to the classroom until you arrive. 61-74). Harlen, W. (2001). Laboratory Demonstrations: Do start class by demonstrating key techniques or equipment operation or describing the location and handling of special materials. It is important for the teacher to be a good learner so as to keep up with the changes. Click here to buy this book in print or download it as a free PDF, if available. U.S. Department of Energy. 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. Thousand Oaks, CA: Corwin Press. Journal of Science Teacher Education, 6(2), 120-124. 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. Further research is needed to evaluate these and other efforts to link scientists with K-12 education. The Higher Education Chemistry (RSC), 5 (2), 42-51. 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. Schulze (Eds. Mahwah, NJ: Lawrence Earlbaum. Teachers help their colleagues by sharing instructional resources. National Research Council. Resource Provider. Atkin, P. Black, and J. Coffey (Eds.). It was implemented over four day-long Saturday sessions spread over a semester.

Loucks-Horsley, S., Love, N., Stiles, K.E., Mundry, S., and Hewson, P.W. The institute included a blend of modeling, small group work, cooperative learning activities, and theoretical and research-based suggestions (p. 122). After completion of the course, teachers classroom behaviors were videotaped and analyzed against traditional and reformed instructional strategies. Bayer Corporation. All rights reserved. Since the 19th century, when schools began to teach science systematically, the laboratory has become a distinctive feature of chemistry learning. Teachers play a critical role in leading laboratory experiences in ways that support student learning. (1998). 791-810). (Working paper prepared in collaboration with the National Conference of State Legislatures.) 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 authors concluded that professional development activities that are short-term interventions have virtually no effect on teachers behaviors in leading laboratory experiences. ), International handbook of science education (pp. Available at: http://www.fhcrc.org/education/sep/ [accessed Feb. 2005]. The role of teacher in the acquisition of scientific knowledge in Secondary School Science class cannot be underestimated. Chapel Hill, NC : Horizon Research. (2004). Glagovich, N., and Swierczynski, A. 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. Millar, R., and Driver, R. (1987). The role of the laboratory in science teaching: Neglected aspects of research. Reynolds (Ed. 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. (2004). U.S. Department of Education. Washington, DC: National Academy Press. Providing Expert Assistance to Schools and Teachers. ), Development in school finance, 1996. For example, teachers realized that there is no unique method called the scientific method, after comparing the methods used in different labs, such as a biochemistry lab, engineering lab, and zoos. Cumulative and residual effects of teachers on future student academic achievement. Project ICAN: Inquiry, Context, and Nature of Science. In this section, we describe the types of teacher knowledge and skills that may be required to lead a range of laboratory experiences aligned with our design principles, comparing the required skills with evidence about the current state of teachers knowledge and skills. Teachers design and carry out an open-ended field research project, of their own choosing. (1999). (2004). Journal of College Science Teaching, 33(6). 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). Transforming teaching in math and science: How schools and districts can support change. Seeking more effective outcomes from science laboratory experiences (Grades 7-14): Six companion studies. 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). 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. van Zee, E., and Minstrell, J. 1 Introduction, History, and Definition of Laboratories, 3 Laboratory Experiences and Student Learning, 5 Teacher and School Readiness for Laboratory Experiences, 7 Laboratory Experiences for the 21st Century, APPENDIX A Agendas of Fact-Finding Meetings, APPENDIX B Biographical Sketches of Committee Members and Staff. They found a large number of preparations, tried each one out, and identified one method as most likely to succeed with the introductory students. Fred Hutchinson Cancer Research Center. Fraser and K.G. Laboratories in science education: Understanding the history and nature of science. Goldhaber, D.D., and Brewer, D.J. develop and implement comprehensive safety policies with clear procedures for engaging in lab activities; ensure that these policies comply with all applicable local, state, and federal health and safety codes, regulations, ordinances, and other rules established by the applicable oversight organization, including the Occupational Safety & Health London, England: Routledge. A professor engaged upper level chemistry majors in trying to create a foolproof laboratory activity to illustrate the chemistry of amines for introductory students. A Japanese high school language lab shows students' positions However, the students were surprised that methods taken from the literature did not always work. 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. 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. How do teachers work and learnspecifically related to labs. Periodic checks indicated that the science internship helped teachers improve their understanding of [the nature of science] and [science inquiry]. To lead laboratory experiences that incorporate ongoing student discussion and reflection and that focus on clear, attainable learning goals, teachers require pedagogical content knowledge. (71) $4.50. 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. However, the undergraduate education of future science teachers does not currently prepare them for effective laboratory teaching. Journal of the Learning Sciences, 6(2), 227-269. Available at: http://www.scied.science.doe.gov/scied/LSTPD/about.htm [accessed Feb. 2005]. Pedagogical content knowledge may include knowing what theories of natural phenomena students may hold and how their ideas may differ from scientific explanations, knowledge of the ideas appropriate for children to explore at different ages, and knowledge of ideas that are prerequisites for their understanding of target concepts. They felt confident to guide their students through the same process, where there is no right answer.. 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. Evaluating the evidence. (1998). Journal of Chemical Education, 75(1), 100-104. 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. It may also be because teachers lack the content knowledge, pedagogical content knowledge, general pedagogical knowledge, and knowledge of assessment required to lead such discussions (Maienschein, 2004; Windschitl, 2004). McComas, W.F., and Colburn, A.I. Science Education, 77(1), 25-46. In W. Fowler (Ed. 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.
