Educational Researcher, 15, 4-14. Linn, E.A. Currently, few teachers lead this type of sense-making discussion (Smith, Banilower, McMahon, and Weiss, 2002). Paper prepared for the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. International Journal of Science Education 22(7), 665-701. Background: ), Proceedings of the Conference on K-12 Outreach from University Science Departments. 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. 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. 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. (1998). Teachers need to listen in a way that goes well beyond an immediate right or wrong judgment. 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. The effects of instruction on college nonmajors conceptions of respiration and photosynthesis. In addition, few high school teachers have access to curricula that integrate laboratory experiences into the stream of instruction. 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.

As discussed in Chapters 2 and 3, there are curricula that integrate laboratory experiences into the stream of instruction and follow the other instructional design principles. Philadelphia: Open University Press. (2004). 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).

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). Science Education, 77, 261-278. 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. At Vanderbilt University, Catley conducts a summer-long course on research in organismal biology. Harrison and Killion (2007) defined the roles of . 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. It appears that the uneven quality of current high school laboratory experiences is due in part to the preparation of science teachers to lead these experiences. Goldhaber, D.D., and Brewer, D.J. Helping students attain the learning goals of laboratory experiences requires their teachers to have broad and deep understanding of both the processes and outcomes of scientific research. 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. This method can assist children in becoming more engaged readers and developing critical thinking abilities. Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. The functions of the laboratory teaching assistant are to provide instruction, supervision, and assistance, as required, to the students in his/her section. Transforming teaching in math and science: How schools and districts can support change. 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. Hegarty-Hazel, E. (1990). Cambridge, MA: Harvard University Press. 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. London, England: Kluwer Academic. The actual crime scene processing takes place in one day and the entire project can take up to 7 depending on your schedule. Jump up to the previous page or down to the next one. (1996).

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. Teaching Assistant Responsibilities Arrive on time & remain in lab. Abstract available at: http://epx.sagepub.com/cgi/content/abstract/17/5/613 [accessed May 2005]. Statistical analysis report. 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. (1986). Those who understand: Knowledge growth in teaching. 6. Javonovic, J., and King, S.S. (1998). ), Constructivism in education. 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. Improving high school science teachers capacity to lead laboratory experiences effectively is critical to advancing the educational goals of these experiences. Paper presented at the annual meeting of the National Association for Research in Science Teaching, April, St. Louis, MO. Crime scenes are set up and the students play the role of Crime Scene Investigators to process the scene. Knoxville: University of Tennessee Value-Added Research and Assessment Center. Does teacher certification matter? 357-382). These workshops include microteaching (peer presentation) sessions. Washington, DC: National Academy Press. 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. 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. In these discussions, the teacher helps students to resolve dissonances between the way they initially understood a phenomenon and the new evidence. Even teachers who have majored in science may be limited in their ability to lead effective laboratory experiences, because their undergraduate science preparation provided only weak knowledge of science content and included only weak laboratory experiences. 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). In many cases teachers ranked in-service training as their least effective source of learning (Windschitl, 2004, p. 16; emphasis in original). In contrast, a physicist might use mathematics to describe or represent the reflection, transmission, and absorption of light. Washington, DC: National Academy Press. The teachers skills in posing questions and leading discussions affect students ability to build meaning from their laboratory experiences. 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. 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. Retired scientists and engineers: Providing in-classroom support to K-12 science teachers. Duration (total contact hours, span of time). Since the 19th century, when schools began to teach science systematically, the laboratory has become a distinctive feature of chemistry learning. What does research tell us about learning in high school science labs? 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: Brookings Institution. These professionals use specialized instrumentation and techniques to analyze patients' samples, such as blood, urine, body fluids and tissue, and stool. It is unclear whether these and other ad hoc efforts to provide summer research experiences reach the majority of high school science teachers. Cambridge, MA: National Bureau of Economic Research. Tobin, K.G. Goldhaber, D.D., Brewer, D.J., and Anderson, D. (1999). However, many high school teachers currently lack strong academic preparation in a science discipline. 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. Thousand Oaks, CA: Corwin Press. 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. Center for Education. 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. Guiding students to formulate their own research questions and design appropriate investigations requires sophisticated knowledge in all four of the domains we have identified. They must consider how to clearly communicate the learning goals of the laboratory experience to their students. (1995). (Working Paper No. Do all student have access to 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. Student outcomes and the professional preparation of eighth-grade teachers in science and mathematics: NSF/NELS. A focus on deepening teachers knowledge of science or mathematics. Anderson, C., Sheldon, T., and Dubay, J. American Educational Research Journal 35(3), 477-496. National Center for Education Statistics. Journal of Research in Science Teaching, 27, 761-776. Lee, O., and Fradd, S.H. Mahwah, NJ: Lawrence Earlbaum. As teachers move beyond laboratory experiences focusing on tools, procedures, and observations to those that engage students in posing a research question or in building and revising models to explain their observations, they require still deeper levels of science content knowledge (Windschitl, 2004; Catley, 2004). 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. 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). Enforcing laboratory rules . The group employs a variety of long-term strategies, such as engaging teachers in curriculum development and adaptation, action research, and providing on-site support by lead teachers (Linn, 1997; Lederman, 2004). National Research Council. Note: The suggestions below were generated by a group of U-M GSIs based on their experiences teaching in a physics lab course. One theme that emerges from such research is that the content knowledge gained from undergraduate work is often superficial and not well integrated. Reynolds (Ed. There are promising examples of teacher professional development focused on laboratory experiences. Sanders, W.L., and Rivers, J.C. (1996). Specifically, it challenges the assumption that having a college degree in science, by itself, is sufficient to teach high school science. Rockville, MD: Westat. Data from the National Center for Education Statistics (2004) show variation in teacher qualifications from one science discipline to another. Lunetta, V.N. For example, the U.S. Department of Energy (DOE) launched its Laboratory Science Teacher Professional Development Program in 2004. 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. 791-810). Other duties include reinforcing laboratory housekeeping and safety protocol, coordinating with other engineering departments, and receiving, installing, and maintaining laboratory supplies and equipment. teacher is teaching both chemistry and physics, requiring more preparation time (American Association of Physics Teachers, 2002). 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). Portsmouth, NH: Heinemann. However, it also reveals some gaps in the . Periodic checks indicated that the science internship helped teachers improve their understanding of [the nature of science] and [science inquiry]. 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. Journal of Personnel Evaluation in Education, 11(1), 57-67. Organizational conditions that support inquiry in high school science instruction. In an ideal world, administrators would provide adequate laboratory space and time to allow students to continue investigations over several weeks or months, and they would also provide time for students to work outside regular school hours. Khalic, A., and Lederman, N. (2000). Journal of Science Education and Technology, 4(2), 103-126. However, their study was criticized for being conducted in laboratory environment (Taylor, Ntoumanis, . ), International handbook of science education (pp. 100 Washtenaw Ave. Ann Arbor, MI 48109-2218, Strategies for Effective Teaching in the Laboratory Class, 2021Regents of the University of Michigan. 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. 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. How can school organization contribute to effective laboratory teaching. In this section we describe the difficulty school administrators encounter when they try to support effective laboratory teaching. (2000). 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. fessional development aligned with the curricula leads to increases in students progress toward the goals of laboratory experiences (Slotta, 2004).

Science Education, 77(3), 301-317. Respecting childrens own ideas. 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). The authors concluded that professional development activities that are short-term interventions have virtually no effect on teachers behaviors in leading laboratory experiences. Slotta, J.D. They appeared to have little understanding of the field writ large. in a limited range of laboratory experiences that do not follow the principles of instructional design identified in Chapter 3.
