The research comprised both quantitative and qualitative approaches. Evaluating the effect of teacher degree level on educational performance. Results of the study also confirmed the effectiveness of providing active learning opportunities. They must consider how to clearly communicate the learning goals of the laboratory experience to their students. One study indicated that significant change in teaching practice required about 80 hours of professional development (Supovitz and Turner, 2000). to the content of textbooks, to visual aids, or to laboratory equipment. Focusing laboratory experiences on clear learning goals requires that teachers understand assessment methods so they can measure and guide their students progress toward those goals. For example, the U.S. Department of Energy (DOE) launched its Laboratory Science Teacher Professional Development Program in 2004. an increasingly important aspect of their general pedagogical knowledge. As is known, it is suggested that closedended - experiments cannot contribute much to meaningful the learning of students [13]. 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. (71) $4.50. Examining the effects of a highly rated curriculum unit on diverse students: Results from a planning grant. 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. 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. 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. However, formulating such questions can be difficult (National Research Council, 2001a, 2001b). Mahwah, NJ: Lawrence Earlbaum. ), The student laboratory and the curriculum (pp. What is the current status of labs in our nations high schools as a context for learning science? 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. 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). (2001a). (2001). Meaning making in secondary science classrooms. 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. Studies in Science Education, 14, 33-62. Washington, DC: Author. 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. In M.D. Learning in the laboratory: Some thoughts from the literature. (1994). 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. Journal of Research in Science Teaching, 39(3), 205-236. 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. The laboratory science teacher professional development program. Journal of Personnel Evaluation in Education, 11(1), 57-67. Can schools narrow the black-white test score gap? 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. At Vanderbilt University, Catley conducts a summer-long course on research in organismal biology. Bayer Corporation. There are promising examples of teacher professional development focused on laboratory experiences. 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. 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. It may be useful, however, to begin . Linn, M.C., Davis, E.A., and Bell, P. (2004). To determine the current role of laboratory schools in the United States, the 123 existing laboratory schools were surveyed. 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). To date, over 400 RE-SEED volunteers have worked with schools in 10 states. It is important for the teacher to be a good learner so as to keep up with the changes. Engaging students in analysis of data gathered in the laboratory and in developing and revising explanatory models for those data requires teachers to be familiar with students practical equipment skills and science content knowledge and be able to engage in sophisticated scientific reasoning themselves. Teachers design and carry out an open-ended field research project, of their own choosing. Journal of Research in Science Teaching. 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. Jump up to the previous page or down to the next one. Trumbull, D., and Kerr, P. (1993). 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). Hilosky, A., Sutman, F., and Schmuckler, J. 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. 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. Portsmouth, NH: Heinemann. Gamoran, A. Effects of professional development on teachers instruction: Results from a three-year longitudinal study. laboratory as well as for the laboratory use in science teaching. (ED 409-634.) 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. Designing a community of young learners: Theoretical and practical lessons. 153-186). educational outcomes (Ferguson, 1998; Goldhaber, 2002; Goldhaber, Brewer, and Anderson, 1999; Hanushek, Kain, and Rivkin, 1999; Wright, Horn, and Sanders, 1997). Properly designed laboratory investigations should: have a definite purpose that is communicated clearly to students; focus on the processes of science as a way to convey content; incorporate ongoing student reflection and discussion; and enable students to develop safe and conscientious lab habits and procedures (NRC 2006, p. 101-102). Note: The suggestions below were generated by a group of U-M GSIs based on their experiences teaching in a physics lab course. Available at: http://www7.nationalacademies.org/bose/June_3-4_2004_High_School_Labs_Meeting_Agenda.html [accessed May 2005]. The culture of education. Generally, the body of research is weak, and the effects of teacher quality on student outcomes are small and specific to certain contexts. 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. Chapel Hill, NC: Horizon Research. Enforcing laboratory rules . (1998). 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.. Figure 1. Fulfilling the promise: Biology education in the nations schools. Research conducted in teacher education programs provides some evidence of the quality of preservice science education (Windschitl, 2004). Lee and Fradd (1998) and others observe that some scientific values and attitudes are found in most cultures (e.g., wonder, interest, diligence, persistence, imagination, respect toward nature); others are more characteristic of Western science. Requirements for professional development of in-service science teachers differ widely from state to state. Is laboratory-based instruction in beginning college-level chemistry worth the effort and expense? Available at: http://www.bayerus.com/msms/news/facts.cfm?mode=detailandid-survey04 [accessed Dec. 2004]. 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. Understanding cellular respiration: An analysis of conceptual change in college biology. 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. The paraprofessional would help with setup, cleanup, community contacts, searching for resources, and other types of support (National Science Teachers Association, 1990). Educational Policy, 14(3), 331-356. National Science Teachers Association. Its the nature of the beast: The influence of knowledge and intentions on learning and teaching nature of science. DeSimone and others conducted a three-year longitudinal study of professional development in science and mathematics provided by school districts. Further research is needed to examine the scope and effectiveness of the many individual programs and initiatives. Organizational conditions that support inquiry in high school science instruction. 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). The actual crime scene processing takes place in one day and the entire project can take up to 7 depending on your schedule. 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. Hofstein, A., and Lunetta, V.N. Glagovich, N., and Swierczynski, A. Teachers, Laboratory Attendants and Gardeners must be made to attend, at regular . Science Teacher (October), 40-43. They found a large number of preparations, tried each one out, and identified one method as most likely to succeed with the introductory students. The web-based inquiry science environment (WISE): Scaffolding knowledge integration in the science classroom. Educating teachers of science, mathematics, and technology. 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). Washington, DC: Author. Laboratory Instructors are responsible for maintaining the routine preventative maintenance of all laboratory equipment. Key words: Laboratory, chemistry, teaching, achievement, students. Cambridge, MA: National Bureau of Economic Research. The following 10 roles are a sampling of the many ways teachers can contribute to their schools' success. American Association of Physics Teachers. Atkin and J.E. Share a link to this book page on your preferred social network or via email. One theme that emerges from such research is that the content knowledge gained from undergraduate work is often superficial and not well integrated. We then compare the desired skills and knowledge with information about the current skills and knowledge of high school science teachers. The role of the laboratory in science teaching: Neglected aspects of research. Fred Hutchinson Cancer Research Center. 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. 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). Journal of Research in Science Teaching, 31, 621-637. (2002). Linn, E.A. 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. Teachers who had engaged in even more intensive professional development, lasting at least 160 hours, were most likely to employ several teaching strategies aligned with the design principles for effective laboratory experiences identified in the research. These workshops include microteaching (peer presentation) sessions. Science teachers may be modeling instructional practices they themselves witnessed or experienced firsthand as students in college science classes. (1997). About this Course. (2004). 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. Presentation to the NRC Committee on High School Science Laboratories, March 29, Washington, DC. Methods of assessing student learning in laboratory activities include systematically observing and evaluating students performance in specific laboratory tasks and longer term laboratory investigations. However, an analysis of national survey data indicates that teachers in block schedules do not incorporate more laboratory experiences into their instruction (Smith, 2004). Linn, M.C. The contents of the institute were developed on the basis of in-depth field interviews and literature reviews to tap the practical knowledge of experienced science teachers. In E. Hegarty-Hazel (Ed. Minstrell, J., and van Zee, E.H. (2003). Ferguson, R. (1998). (1995). This lack of discussion may be due to the fact that high school science teachers depend heavily on the use of textbooks and accompanying laboratory manuals (Smith et al., 2002), which rarely include discussions. Committee on Science and Mathematics Teacher Preparation, Center for Education. Available at: http://www7.nationalacademies.org/bose/July_12-13_2004_High_School_Labs_Meeting_Agenda.html [accessed May 2005]. While teachers play an active role in lecture-based teaching methods, the students' role is usually reduced to sitting at their desks and listening passively to their teachers, to all. East Lansing, MI: National Center for Research in Teacher Education. Zahopoulos, C. (2003). Mahwah, NJ: Lawrence Earlbaum. Cambridge, MA: Harvard University Press. Current professional development for science teachers is uneven in quantity and quality and places little emphasis on laboratory teaching. Transforming teaching in math and science: How schools and districts can support change. Available at: http://www7.nationalacademies.org/bose/June_3-4_2004_High_School_Labs_Meeting_Agenda.html [accessed Oct. 2004]. 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). Chemistry laboratories play an essential role in the education of undergraduate Science, Technology, Engineering, and Mathematics (STEM) and non-STEM students. 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. 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.
