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). It was implemented over four day-long Saturday sessions spread over a semester. For example, the teacher might use descriptive or qualitative language or images to convey concepts related to. These professionals use specialized instrumentation and techniques to analyze patients' samples, such as blood, urine, body fluids and tissue, and stool. 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. 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).

PDF Classroom Teachers' Opinions on Science Laboratory Practices Teaching Assistant Responsibilities Arrive on time & remain in lab. Do you want to take a quick tour of the OpenBook's features? 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). Gallagher, J. The effects of instruction on college nonmajors conceptions of respiration and photosynthesis. Many schools schedule eight 40- to 55-minute class periods, so that following the AAPT guidelines would allow physics teachers two preparation periods. A student lab assistant ensures that students do not practice any unsafe behaviors in the lab. Improving science teachers conceptions of nature of science: A critical review of the literature. Show this book's table of contents, where you can jump to any chapter by name. 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). The organization and structure of most high schools impede teachers and administrators ongoing learning about science instruction and the implementation of quality laboratory experiences. 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. (1998). PDF The role and purpose of practical work in the teaching and earning of Khalic, A., and Lederman, N. (2000). 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. The program was designed in part to address weakness in science teachers understanding of the nature of science, which was documented in earlier research (Khalic and Lederman, 2000; Schwartz and Lederman, 2002). The research comprised both quantitative and qualitative approaches. Priestley, W., Priestley, H., and Schmuckler, J. Current professional development for science teachers is uneven in quantity and quality and places little emphasis on laboratory teaching. 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. Pomeroy, D. (1993). thus expanding the teaching or training role; sometimes they are excluded purposely, such as in the case of France, where teachers are only responsible for the actual instruction and the remainder of .

However, it also reveals some gaps in the . Beyond process. 99-138). Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). 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). In many cases teachers ranked in-service training as their least effective source of learning (Windschitl, 2004, p. 16; emphasis in original). School administrators have a strong influence on whether high school science teachers receive the professional development opportunities needed to develop the knowledge and skills we have identified. In addition, there is little research on whether use of block scheduling influences teachers instruction or enhances student learning. What does research tell us about learning in high school science labs? 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. You're looking at OpenBook, NAP.edu's online reading room since 1999.

Williams, M., Linn, M.C., Ammon, P., and Gearhart, M. (2004). 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). Research conducted in teacher education programs provides some evidence of the quality of preservice science education (Windschitl, 2004). McDiarmid, G.S., Ball, D.L., and Anderson, C.W. 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). 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 Available at: http://www.sedl.org/connections/research-syntheses.html [accessed May 2005]. 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. Baumgartner, E. (2004). (2000). Meaning making in secondary science classrooms. Program faculty report that many teachers tend to dwell on hands-on activities with their students at the expense of linking them with the nature of science and with abilities associated with scientific inquiry.

Sign up for email notifications and we'll let you know about new publications in your areas of interest when they're released. 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. Cobus van Breda was born and schooled in Windhoek, Namibia. 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). Assistants show the students how to handle chemical spills, dispose of broken glassware and get rid of non-hazardous and chemical waste . Improving high school science teachers capacity to lead laboratory experiences effectively is critical to advancing the educational goals of these experiences. 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). In this program, faculty modeled lower-level inquiry-oriented instruction focused on short laboratory sessions with limited lecturing and no definitions of terms. Periodic checks indicated that the science internship helped teachers improve their understanding of [the nature of science] and [science inquiry]. More than 90 percent of the class indicated that the experiment was highly effective in demonstrating the difficulty of scientific investigations and the possibility of failure in science (Glagovich and Swierczynski, 2004). Gamoran, A., Anderson, C.W., Quiroz, P.A., Seceda, W.G., Williams, T., and Ashmann, S. (2003). Enforcing laboratory rules . The role of the laboratory in science learning. PDF The school science laboratory: Considerations of learning, technology Finally, adequate time is essential for student learning in laboratory experiences. 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. 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. Linn, E.A. As Tobin (Eds. We then present promising examples of approaches to enhancing teachers capacity to lead laboratory experiences. Knoxville: University of Tennessee Value-Added Research and Assessment Center. Do you enjoy reading reports from the Academies online for free? It means focusing the students own questions. Requirements for professional development of in-service science teachers differ widely from state to state. teacher in the classroom and thus cause tension like tools, materials, negative working conditions, student violence on teachers, increasing teacher expectations and tiredness of teacher. (71) $4.50. 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. Gamoran and others studied six sites where teachers and educational researchers collaborated to reform science and mathematics teaching, focusing on teaching for understanding. Organizational conditions that support inquiry in high school science instruction. They should be proactive in every aspect of laboratory safety, making safety a priority. (1997). Playing this critical role requires that teachers know much more than how to set up equipment, carry out procedures, and manage students physical activities. Linn, M.C. However, the undergraduate education of future science teachers does not currently prepare them for effective laboratory teaching. 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). fessional development aligned with the curricula leads to increases in students progress toward the goals of laboratory experiences (Slotta, 2004). 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 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). About this Course. Raleigh: Science House, North Carolina State University. Laboratory learning: Addressing a neglected dimension of science teacher education. 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. Generally, the body of research is weak, and the effects of teacher quality on student outcomes are small and specific to certain contexts. Chemistry laboratories play an essential role in the education of undergraduate Science, Technology, Engineering, and Mathematics (STEM) and non-STEM students. A survey of students, teachers, and volunteers yielded positive results. 7082.) Register for a free account to start saving and receiving special member only perks. 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. Mortimer, E., and Scott, P. (2003). The culture of education. Presentation to the NRC Committee on High School Science Laboratories, March 29, Washington, DC. 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. Teacher awareness of students science needs and capabilities may be enhanced through ongoing formative assessment. educational outcomes (Ferguson, 1998; Goldhaber, 2002; Goldhaber, Brewer, and Anderson, 1999; Hanushek, Kain, and Rivkin, 1999; Wright, Horn, and Sanders, 1997). They also modeled longer postlaboratory activities focused on using student data and observations as the engine for further instruction. Shared teacher planning time may be a critical support for improved laboratory teaching, because of the unique nature of laboratory education. 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). ), Proceedings of the Conference on K-12 Outreach from University Science Departments. National Center for Family and Community Connections with Schools. workincluding verification workrequires deep knowledge of the specific science concepts and science processes involved in such work (Millar, 2004). Available at: http://www.scied.science.doe.gov/scied/LSTPD/about.htm [accessed Feb. 2005]. (2001a). 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. 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. Deep disciplinary expertise is necessary to help students learn to use laboratory tools and procedures and to make observations and gather data. New York: Teachers College Press. (2004). 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. East Lansing, MI: National Center for Research in Teacher Education. can be sequenced into a flow of science instruction in order to integrate student learning of science content and science processes. At the same time, teachers must address logistical and practical concerns, such as obtaining and storing supplies and maintaining laboratory safety. (2000). Responsibilities of Teachers Clinical Supervision of Medical Students Resident, Fellow and Graduate Teaching Assistant as Teacher Policy Responsibilities of Learners Course Directors' Expectations of Students The teacher-learner relationship confers rights and responsibilities on both parties. to the content of textbooks, to visual aids, or to laboratory equipment. High school science laboratories. 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. 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. Hofstein, A., and Lunetta, V.N. In W. Fowler (Ed. Laboratories in science education: Understanding the history and nature of science. 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. ), Faculty development for improving teacher preparation (pp. Arlington, VA: National Science Teachers Association. New York: City College Workshop Center. U.S. Department of Education. At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory work, and the case for laboratory . (Working Paper No. 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. (2002). (1990). 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). Use these dos and donts to help you think about what you can do to be a successful new instructor: Allen, D., OConnell, R., Percha, B., Erickson, B., Nord, B., Harper, D., Bialek, J., & Nam E. (2009). 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. 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. in a limited range of laboratory experiences that do not follow the principles of instructional design identified in Chapter 3. AAPT guidelines for high school physics programs. Advanced Practice: Doctorate in Clinical Laboratory Science Other studies have also found that most teachers do not experience sustained professional development and that they view it as ineffective (Windschitl, 2004). Collaborator. In this section we describe the difficulty school administrators encounter when they try to support effective laboratory teaching. In addition, few high school teachers have access to curricula that integrate laboratory experiences into the stream of instruction. Goldhaber, D.D. Why staying ahead one chapter doesnt really work: Subject-specific pedagogy. 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). (2004). Education Economics, 7(3), 199-208. This chapter describes some of the factors contributing to the weakness of current laboratory experiences. Data from the 2000 National Survey of Science and Mathematics Education. In B.J. Sanders, M. (1993). Active assessment for active learning. Administrators allocate time, like other resources, as a way to support teachers in carrying out these routines. What do they contribute to science learning? 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. A focus on deepening teachers knowledge of science or mathematics. Educational Researcher, 15, 4-14. On the basis of a review of the available research, Lunetta (1998, p. 253) suggests that, for students, time should be provided for engaging students in driving questions, for team planning, for feedback about the nature and meaning of data, and for discussion of the implications of findings, and laboratory journals should provide opportunities for individual students to reflect upon and clarify their own observations, hypotheses, conceptions.. Tobin, K.G. In J.M. Do higher salaries buy better teachers? Key words: Laboratory, chemistry, teaching, achievement, students.

Journal of Research in Science Teaching, 30, 919-934. Hammer, D. (1997). Arrangements must be made with Instructor to cover unavoidable absences or planned breaks. However, many high school teachers currently lack strong academic preparation in a science discipline. In contrast, a physicist might use mathematics to describe or represent the reflection, transmission, and absorption of light. Journal of Research in Science Teaching, 20, 745-754. Participant teachers were also interviewed. Available at: http://www.fhcrc.org/education/sep/ [accessed Feb. 2005]. Mathematics and science teachers reported more frequently than other teachers that job dissatisfaction was the reason they left their jobs. (2004). or use these buttons to go back to the previous chapter or skip to the next one. National Research Council. Journal of Research in Science Teaching. Smith, S. (2004). How can school organization contribute to effective laboratory teaching. Currently, few teachers lead this type of sense-making discussion (Smith, Banilower, McMahon, and Weiss, 2002). Fulfilling the promise: Biology education in the nations schools. It was also clear that teachers enhanced their understanding of science subject matter specific to the lab they experienced. They should advise teachers where any concerns arise regarding safety, scheduling or resourcing of 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. Goldhaber, D.D., Brewer, D.J., and Anderson, D. (1999). Preordained science and student autonomy: The nature of laboratory tasks in physics classrooms. In the Seattle program, teachers attend a 13-day summer workshop in which they work closely with each other, master teachers, and program staff to develop expertise in molecular biology. University of Michigan Physics Department: GSI training course. Lee, O. As is known, it is suggested that closedended - experiments cannot contribute much to meaningful the learning of students [13]. Mahwah, NJ: Lawrence Erlbaum. 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. 9-13 Thus, medical laboratory professionals can be key members of the interprofessional health care team. The guidelines note that simply maintaining the laboratory requires at least one class period per day, and, if schools will not provide teachers with that time, they suggest that those schools either employ laboratory technicians or obtain student help. In D.G. Marjolein Dobber a. , Rosanne Zwart b. , Marijn Tanis a b 1. , Bert van Oers a. 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. One theme that emerges from such research is that the content knowledge gained from undergraduate work is often superficial and not well integrated. These might include websites, instructional materials, readings, or other resources to use with students. Few professional development programs for science teachers emphasize laboratory instruction. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. 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). Millar, R. (2004). This paper explores the role of laboratory and field-based research experiences in secondary science education by summarizing research documenting how such activities promote science learning. Schulze (Eds. Final report on the evaluation of the National Science Foundations Instructional Materials Development Program. Science teachers may be modeling instructional practices they themselves witnessed or experienced firsthand as students in college science classes. Supovitz, J.A., and Turner, H.M. (2000). Studies in Science Education, 14, 33-62. Available at: http://www7.nationalacademies.org/bose/June_3-4_2004_High_School_Labs_Meeting_Agenda.html [accessed Oct. 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. Presentation to the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. It often consists mostly of one-day (or shorter) workshops focusing on how-to activities that are unlikely to challenge teachers beliefs about teaching and learning that support their current practice (DeSimone, Garet, Birman, Porter, and Yoon, 2003). Lynch, S., Kuipers, J., Pike, C., and Szeze, M. (in press). For example, Northeastern University has established a program called RE-SEED (Retirees Enhancing Science Education through Experiments and Demonstration), which arranges for engineers, scientists, and other individuals with science backgrounds to assist middle school teachers with leading students in laboratory experiences. 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). (1997). Washington, DC: National Academy Press. Gess-Newsome, J., and Lederman, N. (1993). The changing nature of work: Implications for occupational analysis. 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.
