The role of the laboratory in science teaching: Neglected aspects of research. Seattle: University of Washington, Center for the Study of Teaching and Policy. Khalic, A., and Lederman, N. (2000). There are promising examples of teacher professional development focused on laboratory experiences. 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 case study of his experience, this professor called for reducing science teachers class loads so they have more time to reflect on and improve their own practice.

Coherence (consistency with teachers goals, state standards, and assessments). (1990). Teachers College Record, 105(3), 465-489. A research agenda. Rockville, MD: Westat. 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. The effects of instruction on college nonmajors conceptions of respiration and photosynthesis. Some individual teachers told our committee that they did not have adequate preparation and cleanup time. (1998). 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). Since the 19th century, when schools began to teach science systematically, the laboratory has become a distinctive feature of chemistry learning. Lab Professional - ASCP Guiding students through the complexity and ambiguity of empirical. The poor quality of laboratory experiences of most high school students today results partly from the challenges that laboratory teaching and learning pose to school administrators. (2001b). 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. At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory work, and the case for laboratory . Time constraints can also discourage teachers from the challenges of setting up and testing laboratory equipment and materials. Organizational conditions that support inquiry in high school science instruction. Gamoran and others studied six sites where teachers and educational researchers collaborated to reform science and mathematics teaching, focusing on teaching for understanding. 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. International Journal of Science Education 22(7), 665-701. Further research is needed to inform design of laboratory-focused teacher professional development that can support teachers in improving laboratory instruction. 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. In addition, few high school teachers have access to curricula that integrate laboratory experiences into the stream of instruction. The institute included a blend of modeling, small group work, cooperative learning activities, and theoretical and research-based suggestions (p. 122). (2002). The role of practical work in the teaching and learning of science. Characterizing Instructional Practices in the Laboratory: The 4.01 Responsibilities of Teachers and Learners The 2000 National Survey of Science and Mathematics Education: Compendium of tables. Studies of the few schools and teachers that have implemented research-based science curricula with embedded laboratory experiences have found that engaging teachers in developing and refining the curricula and in pro-. The extent of student learning in any educational environment depends largely on the effectiveness of the instructors. Linn, M.C., Davis, E.A., and Bell, P. (2004). Committee on Science and Mathematics Teacher Preparation, Center for Education. Philadelphia: Open University Press. 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). Drawing up suitable assessments and delivering helpful feedback to students, parents, and other teachers. They need to carefully consider written work and what they observe while students engage in projects and investigations. Playing this critical role requires that teachers know much more than how to set up equipment, carry out procedures, and manage students physical activities. We begin by identifying some of the knowledge and skills required to lead laboratory experiences aligned with the goals and design principles we have identified. Educational Researcher, 15, 4-14. Research conducted in teacher education programs provides some evidence of the quality of preservice science education (Windschitl, 2004). Once on the job, science teachers have few opportunities to improve their laboratory teaching. Catley (2004) reports that having gone through the process of frustration, false starts and the elation of completion, [the teachers] came away with a deeper understanding of how inquiry works and a sense of empowerment. little information is available on the effectiveness of these efforts. Educational Evaluation and Policy Analysis, 24(2), 81-112. Seattle: Author. Presentation to the NRC Committee on High School Science Laboratories, March 29, Washington, DC. 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.

London, England: Kluwer Academic. ), Internet environments for science education. 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. Volunteers receive training, a sourcebook of activities appropriate for middle school students, a kit of science materials, and a set of videotapes. Gallagher, J. Linn, E.A. 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. In addition, there is little research on whether use of block scheduling influences teachers instruction or enhances student learning. Journal of Research in Science Teaching, 27, 761-776. The arts and science as preparation for teaching. 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. 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. In M.C. In a year-long study of prospective biology teachers (Gess-Newsome and Lederman, 1993), the participants reported never having thought about the central ideas of biology or the interrelationships among the topics. Harrison and Killion (2007) defined the roles of . 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. Over the course of a years worth of pedagogical preparation and field experiences, the new teachers began to reorganize their knowledge of biology according to how they thought it should be taught. Once again. A series of studies conducted over the past several decades has shown that teachers are one of the most important factors influencing students. Pomeroy, D. (1993). One study indicated that significant change in teaching practice required about 80 hours of professional development (Supovitz and Turner, 2000). Fraser and K.G. Laboratory Learning: An Inservice Institute. Teachers do not have sole responsibility for carrying out laboratory experiences that are 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, as suggested by the research. These might include websites, instructional materials, readings, or other resources to use with students. Tobin (Eds. The inequities in the availability of academically prepared teachers may pose a serious challenge to minority and poor students progress toward the.

Austin, TX: Southwest Educational Development Laboratory. In contrast, a physicist might use mathematics to describe or represent the reflection, transmission, and absorption of light. (2003). Improving high school science teachers capacity to lead laboratory experiences effectively is critical to advancing the educational goals of these experiences. 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 investigators found that professional development focused. Teacher awareness of students science needs and capabilities may be enhanced through ongoing formative assessment. The Role of Laboratory in Science Teaching and Learning What do they contribute to science learning? 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). 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).

Baumgartner, E. (2004). Among these factors, curriculum has a strong influence on teaching strategies (Weiss, Pasley, Smith, Banilower, and Heck, 2003). 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.

ROLE DESCRIPTION Education Support Employee Laboratory Assistant The Integral Role of Laboratory Investigations in Science - NSTA Javonovic, J., and King, S.S. (1998). (1997). A study of Ohios Statewide Systemic Initiative in science and mathematics also confirmed that sustained professional development, over many hours, is required to change laboratory teaching practices (Supovitz, Mayer, and Kahle, 2000, cited in Windschitl, 2004, p. 20): A highly intensive (160 hours) inquiry-based professional development effort changed teachers attitudes towards reform, their preparation to use reform-based practices, and their use of inquiry-based teaching practices. McDiarmid, G.S., Ball, D.L., and Anderson, C.W. 99-138). The Role of the Laboratory in Science Teaching: Neglected Aspects of Wright, S.P., Horn, S., and Sanders, W. (1997). In 2000, according to a nationally representative survey of science teachers, most school administrators provided inadequate time for shared planning and reflection to improve instruction. 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. Paper presented at the National Association for Research in Science Teaching meeting, March 23, Chicago, IL. Block scheduling is one approach schools have used to provide longer periods of time for laboratory activities and discussion. The National Survey of Science and Mathematics Education: Trends from 1977 to 2000. New York: City College Workshop Center. Data from a 2000 survey of science and mathematics education indicate that most current science teachers participate infrequently in professional development activities, and that many teachers view these activities as ineffective (Hudson, McMahon, and Overstreet, 2002). However, many high school teachers currently lack strong academic preparation in a science discipline. Mathematics and science teachers reported more frequently than other teachers that job dissatisfaction was the reason they left their jobs. Roles and Responsibilities of Teaching Assistants McComs (Eds. (Working Paper No. Examining the effects of a highly rated curriculum unit on diverse students: Results from a planning grant. Studies focusing specifically on science teacher quality and student achievement are somewhat more conclusive. 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 . How should student learning in laboratory experiences be assessed? 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. Mortimer, E., and Scott, P. (2003). It is ultimately the role of Laboratory Assistant to facilitate the safe and efficient delivery of the curriculum designed by the teacher. light, such as reflection, transmission, and absorption. It aims to support teachers to improve their teaching skills for active learning in university science laboratory courses. (71) $4.50. These school-based teacher communities, in turn, not only supported teachers in improving their teaching practices, but also helped them create new resources, such as new curricula. Cobus van Breda - Manager of the Sci-Ed Science Education Centre The proper performance of these duties requires the undivided attention of the teaching assistant during each laboratory period. Lab's History Department, which is responsible for educating students in grades 9-12, seeks a teacher with expertise and experience teaching Modern Global or Modern World History coursework. Only 11 percent of responding teachers indicated that science teachers in their school regularly observed other science teachers. Cobus van Breda was born and schooled in Windhoek, Namibia. Available at: http://www7.nationalacademies.org/bose/July_1213_2004_High_School_Labs_Meeting_Agenda.html. 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). 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). Data from the 2000 National Survey of Science and Mathematics Education. Project ICAN includes an intensive three-day summer orientation for science teachers followed by full-day monthly workshops from September through June, focusing on the nature of science and scientific inquiry. Because many current science teachers have demographic backgrounds different from their students (Lee, 2002; Lynch, Kuipers, Pyke, and Szeze, in press), the ability to communicate across barriers of language and culture is. Journal of Research in Science Teaching, 31, 621-637. Their previous, closely prescribed laboratory experiences had not helped them to understand that there are many different ways to effect a particular chemical transformation. 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. Hofstein, A., and Lunetta, V.N. 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). Duration (total contact hours, span of time). (2002). They lock up all the reagents and unplug all electrical equipment to minimize the chances of accidents and fires. Crime scenes are set up and the students play the role of Crime Scene Investigators to process the scene. 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. (1999). The teacher strives to fathom what the student is saying and what is implied about the students knowledge in his or her statements, questions, work and actions. Teachers need to decide what kind of phenomena are important and appropriate for students to study as well as the degree of structure their students require. Science Education, 77(3), 301-317. Journal of the Learning Sciences, 6(2), 227-269. 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. Science Educator, 12(1), 1-9. The research team focused the curriculum on helping students understand these principles, including flow principles, rate principles, total heat flow principles, and an integration principle. Gamoran and colleagues found that, although the educational researchers provided an infusion of expertise from outside each of the six school sites, the professional development created in collaboration with the local schools had its greatest impact in supporting local teachers in developing their own communities. 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. 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 laboratory science teacher professional development program. Science Teacher (October), 40-43. During the school year, teachers may access kits of materials supporting laboratory experiences that use biomedical research tools. Teacher and School Readiness for Laboratory Experiences to the content of textbooks, to visual aids, or to laboratory equipment. Laboratory Instructors are responsible for maintaining the routine preventative maintenance of all laboratory equipment. Available at: http://www.fhcrc.org/education/sep/ [accessed Feb. 2005]. Providing more focused, effective, and sustained professional development activities for more science teachers requires not only substantial financial resources and knowledge of effective professional development approaches, but also a coherent, coordinated approach at the school and district level. Before its too late: A report to the nation from the national commission on mathematics and science teaching for the 21st century. 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.

Hillsdale, NJ: Lawrence Erlbaum. Institute participants also asked for more discussion of assessment methods for laboratory teaching, including the role of video testing, and also recommended inclusion of sessions that address teaching science laboratory classes on a small budget. 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). PDF Classroom Teachers' Opinions on Science Laboratory Practices 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. Other duties include reinforcing laboratory housekeeping and safety protocol, coordinating with other engineering departments, and receiving, installing, and maintaining laboratory supplies and equipment. Rethinking laboratories. teacher is teaching both chemistry and physics, requiring more preparation time (American Association of Physics Teachers, 2002). Duschl, R. (1983). can be sequenced into a flow of science instruction in order to integrate student learning of science content and science processes. 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. 9-13 Thus, medical laboratory professionals can be key members of the interprofessional health care team. 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. 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). Science Education, 77(1), 25-46. Moreover, the teacher console (keyboard) is usually fitted with a tape recorder to monitoring each compartment in the class by the teacher headset and an intercom facility to enable 2-way communication between the teacher and his/her students individually. The condition of education. 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. Do you enjoy reading reports from the Academies online for free? 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. Research on the efficacy of strategies used for professional development related specifically to laboratory experiences, however, is not readily available. Reynolds (Ed.

It is unclear whether these and other ad hoc efforts to provide summer research experiences reach the majority of high school science teachers. 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 Cambridge, MA: National Bureau of Economic Research. School administrators can take several approaches to providing time for this type of ongoing discussion and reflection that supports student learning during laboratory experiences. International Journal of Science Education, 18(7), 775-790. In addition to the many programs to increase teachers knowledge and abilities discussed above, the scientific community sometimes engages scientists to work directly with students.
