The available evidence indicates that the current science teaching workforce lacks the knowledge and skills required to lead a range of effective laboratory experiences. teacher is teaching both chemistry and physics, requiring more preparation time (American Association of Physics Teachers, 2002). laboratory as well as for the laboratory use in science teaching. Teaching for understanding was defined as including a focus on student thinking, attention to powerful scientific ideas, and the development of equitable classroom learning communities. (2004). Maienschein, J. It will show you how laboratory sessions can differ with respect to their aim and expected learning . Hirsch, E., Koppich, J.E., and Knapp, M.S. (2004). 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. Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). Paper presented at the annual meeting of the National Association for Research in Science Teaching, April, St. Louis, MO.

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. Committee on High School Biology Education, Commission on Life Sciences. National Research Council. Most states do not regulate the quality and content of professional development required for renewal of teaching certificates (Hirsch, Koppich, and Knapp, 2001). You're looking at OpenBook, NAP.edu's online reading room since 1999. Linn, E.A. They also modeled longer postlaboratory activities focused on using student data and observations as the engine for further instruction. The actual crime scene processing takes place in one day and the entire project can take up to 7 depending on your schedule. Further research is needed to examine the scope and effectiveness of the many individual programs and initiatives. 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.

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. In D.G. In developing an investigation for students to pursue, teachers must consider their current level of knowledge and skills, the range of possible laboratory experiences available, and how a given experience will advance their learning.

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. Atkin, P. Black, and J. Coffey (Eds.). Science Education, 77(3), 301-317. For example, the U.S. Department of Energy (DOE) launched its Laboratory Science Teacher Professional Development Program in 2004.

This chapter describes some of the factors contributing to the weakness of current laboratory experiences. When one college physics professor taught a high school physics class, he struggled with uncertainty about how to respond to students ideas about the phenomena they encountered, particularly when their findings contradicted accepted scientific principles (Hammer, 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. can be sequenced into a flow of science instruction in order to integrate student learning of science content and science processes. 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. 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. Hillsdale, NJ: Lawrence Erlbaum. Elementary School Journal, 97(4), 401-417. Primary science: Taking the plunge. 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). 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. What can they contribute to science learning? Journal of Research in Science Teaching, 31, 621-637. This course is developed to improve the effectiveness of laboratory classes in higher education. (2000). (1990).

Catley, K. (2004). Washington, DC: National Academy Press. ), Constructivism in education. 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). Mathematics and science teachers reported more frequently than other teachers that job dissatisfaction was the reason they left their jobs. Reporting on a post-institute survey, McComas and Colburn note that a surprising number of teachers felt that the safety sessions were most important (p. 121) (no numbers were reported). (2003). The primary role of a teacher is to establish a learning environment where all students are able to learn and are motivated to learn, an environment that is both challenging and supportive: Establish a learning community consisting of the teacher and the students 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. Professional development opportunities for science teachers are limited in quality, availability, and scope and place little emphasis on laboratory instruction. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. American Association of Physics Teachers. In addition, there is little research on whether use of block scheduling influences teachers instruction or enhances student learning. Teaching Assistant Responsibilities Arrive on time & remain in lab. Not a MyNAP member yet? Despite the weakness of current professional development for laboratory teaching, a growing body of research indicates that it is possible to develop and implement professional development that would support improved laboratory teaching and learning. in a limited range of laboratory experiences that do not follow the principles of instructional design identified in Chapter 3. 1071 Palmer Commons Only 11 percent of responding teachers indicated that science teachers in their school regularly observed other science teachers. Expertise in science alone also does not ensure that teachers will be able to anticipate which concepts will pose the greatest difficulty for students and design instruction accordingly. 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. 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. In chemistry laboratories at large universities, the instructors of record are typically graduate or undergraduate . when studying aspects of biology . Jump up to the previous page or down to the next one. Lederman, N.G. 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. Linn, M.C., Davis, E.A., and Bell, P. (2004). Literature review: The role of the teacher in inquiry-based education. Linn, E.A. 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).

For example, HHMI has funded summer teacher training workshops at the Cold Spring Harbor Laboratory for many years, and also supports an ongoing partnership between the Fred Hutchinson Cancer Research Center and the Seattle, Washington, public schools (Fred Hutchinson Cancer Research Center, 2003). Philadelphia: Open University Press. However, compared with other types of professionals, a higher proportion of teachers leave their positions each year. Currently, most schools are designed to support teaching that follows predictable routines and schedules (Gamoran, 2004). McDiarmid, G.W. (1995). The web-based inquiry science environment (WISE): Scaffolding knowledge integration in the science classroom. Quantitative approach was used to investigate effects of teaching science subjects in absence of science laboratory and to. Guiding students through the complexity and ambiguity of empirical. Davis, and P. Bell (Eds. (2004). Researchers generally agree that the teachers academic preparation in science has a positive influence on students science achievement (U.S. Department of Education, 2000; National Research Council, 2001a). Chapel Hill, NC: Horizon Research. Educational Researcher, 15, 4-14. Coherence (consistency with teachers goals, state standards, and assessments). Is laboratory-based instruction in beginning college-level chemistry worth the effort and expense? Currently, few teachers lead this type of sense-making discussion (Smith, Banilower, McMahon, and Weiss, 2002). Science Education, 88, 28-54. 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 . goals of laboratory experiences. Volunteers receive training, a sourcebook of activities appropriate for middle school students, a kit of science materials, and a set of videotapes. Fraser and K.G. In addition, few high school teachers have access to curricula that integrate laboratory experiences into the stream of instruction. The limited evidence available indicates that some undergraduate science programs do not help future teachers develop full mastery of science subject matter. (2001a). These limits, in turn, could contribute to lower science achievement, especially among poor and minority students. AAPT guidelines for high school physics programs. Do you want to take a quick tour of the OpenBook's features? At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory [I]t represents the blending of content and pedagogy into an understanding of how particular topics, problems, or issues are organized, represented and adapted to the diverse interests and abilities of learners, and presented for instruction. (1998). Washington, DC: Brookings Institution. 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. Drawing up suitable assessments and delivering helpful feedback to students, parents, and other teachers. 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). Currently, teachers rarely provide opportunities for students to participate in formulating questions to be addressed in the laboratory. Hanusek, E., Kain, J., and Rivkin, S. (1999). Gamoran, A. Presentation to the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. 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). The role of the laboratory in science teaching: Neglected aspects of research. They felt confident to guide their students through the same process, where there is no right answer.. University researchers inchoate critiques of science teaching: Implications for the content of pre-service science teacher education. McComas, W.F., and Colburn, A.I. Some individual teachers told our committee that they did not have adequate preparation and cleanup time. 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. School districts, teachers, and others may want to consider these examples, but further research is needed to determine their scope and effectiveness. 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. 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. New York: Teachers College Press. Hegarty-Hazel, E. (1990). The inequities in the availability of academically prepared teachers may pose a serious challenge to minority and poor students progress toward the. Wright, S.P., Horn, S., and Sanders, W. (1997). Weiss, I.R., Pasley, J.D., Smith, P.S., Banilower, E.R., and Heck, D.J.

Using questioning to guide student thinking. In M.D. East Lansing, MI: National Center for Research in Teacher Education. To lead laboratory experiences that incorporate ongoing student discussion and reflection and that focus on clear, attainable learning goals, teachers require pedagogical content knowledge. Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. Among these factors, curriculum has a strong influence on teaching strategies (Weiss, Pasley, Smith, Banilower, and Heck, 2003). Ferguson, R. (1998). Science Teacher, September, 38-41. Laboratory activities have long had a distinct and central role in the science curriculum as a means of making sense of the natural world. Driver, R. (1995). National Science Teachers Association. Teachers need to listen in a way that goes well beyond an immediate right or wrong judgment.
