Other studies have also found that most teachers do not experience sustained professional development and that they view it as ineffective (Windschitl, 2004). Gamoran, A., Anderson, C.W., Quiroz, P.A., Seceda, W.G., Williams, T., and Ashmann, S. (2003). It means figuring out what students comprehend by listening to them during their discussions about science. 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). Teachers need to use data drawn from conversations, observations, and previous student work to make informed decisions about how to help them move toward desired goals. location_onUniversity of Michigan 4. workincluding verification workrequires deep knowledge of the specific science concepts and science processes involved in such work (Millar, 2004). 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. 249-262). ), Constructivism in education. Millar, R. (2004). The role of the laboratory in science teaching: Neglected aspects of research. However, compared with other types of professionals, a higher proportion of teachers leave their positions each year. Further research is needed to evaluate these and other efforts to link scientists with K-12 education. Teachers and teacher aides should lead by example and wear personal protective equipment (PPE); follow and enforce safety rules, procedures, and practices; and demonstrate safety behavior to promote a culture of safety.

Time constraints can also discourage teachers from the challenges of setting up and testing laboratory equipment and materials. goals of laboratory experiences. What does research tell us about learning in high school science labs? Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). Hammer, D. (1997). Currently, few teachers lead this type of sense-making discussion (Smith, Banilower, McMahon, and Weiss, 2002). (2003). In reviewing the state of biology education in 1990, an NRC committee concluded that few teachers had the knowledge or skill to lead effective laboratory experiences and recommended that "major new programs should be developed for providing in-service education on laboratory activities" (National Research Council, 1990, p. 34). (1994). These limits, in turn, could contribute to lower science achievement, especially among poor and minority students. During the school year, teachers may access kits of materials supporting laboratory experiences that use biomedical research tools. DeSimone and others conducted a three-year longitudinal study of professional development in science and mathematics provided by school districts. Portsmouth, NH: Heinemann. The teachers skills in posing questions and leading discussions affect students ability to build meaning from their laboratory experiences. Establishing classroom, lab, and field trip rules and regulations and ensuring that . 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.

Deep disciplinary expertise is necessary to help students learn to use laboratory tools and procedures and to make observations and gather data. 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. Gitomer, D.H., and Duschl, R.A. (1998). McComs (Eds. Literature review: The role of the teacher in inquiry-based education. Arlington, VA: National Science Teachers Association. Review of Educational Research, 52(2), 201-217. However, 66 percent of teachers indicated that they regularly shared ideas and materials with their colleagues, perhaps indicating that they do so on their own time, outside school hours (Hudson et al., 2002). As students analyze observations from the laboratory in search of patterns or explanations, develop and revise conjectures, and build lines of reasoning about why their proposed claims or explanations are or are not true, the teacher supports their learning by conducting sense-making discussions (Mortimer and Scott, 2003; van Zee and Minstrell, 1997; Hammer, 1997; Windschitl, 2004; Bell, 2004; Brown and Campione, 1998; Bruner, 1996; Linn, 1995; Lunetta, 1998; Clark, Clough, and Berg, 2000; Millar and Driver, 1987). (1997). Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. The culture of education. School districts, teachers, and others may want to consider these examples, but further research is needed to determine their scope and effectiveness. To make these choices, they must be aware not only of their own capabilities, but also of students needs and readiness to engage in the various types of laboratory experiences. (2002). ), Internet environments for science education. Washington, DC: National Academy Press. This timely book investigates factors that influence a high school laboratory experience, looking closely at what currently takes place and what the goals of those experiences are and should be. to the content of textbooks, to visual aids, or to laboratory equipment. 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. Science for all, including students from non-English-language backgrounds. 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.

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. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. Lederman, N.G. They found that a heat-flow model was better able to connect to middle school students knowledge about heat and temperature than a molecular-kinetic model (Linn, Davis, and Bell, 2004). Mathematics and science teachers reported more frequently than other teachers that job dissatisfaction was the reason they left their jobs. Journal of Research in Science Teaching, 29, 51-61. 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. The role of teacher in the acquisition of scientific knowledge in Secondary School Science class cannot be underestimated. It is ultimately the role of Laboratory Assistant to facilitate the safe and efficient delivery of the curriculum designed by the teacher.

A study of a much smaller sample of teachers yielded similar findings (Catley, 2004). Paper presented at the National Association for Research in Science Teaching meeting, March 23, Chicago, IL. One study indicated that significant change in teaching practice required about 80 hours of professional development (Supovitz and Turner, 2000). Catley, K. (2004). (2002).

Lynch, S., Kuipers, J., Pike, C., and Szeze, M. (in press). Knowledge of childrens mental and emotional development, of teaching methods, and how best to communicate with children of different ages is essential for teachers to help students build meaning based on their laboratory experiences. When asked whether they had time during the regular school week to work with colleagues on the curriculum and teaching, 69 percent of high school teachers disagreed and 4 percent had no opinion, leaving only 28 percent who agreed. However, many high school teachers currently lack strong academic preparation in a science discipline. Shulman (1986, p. 8) has defined pedagogical content knowledge as: [A] special amalgam of content and pedagogy that is uniquely the province of teachers, their own form of professional understanding.

Qualifications of the public school teacher workforce: Prevalence of out-of-field teaching 1987-88 to 1999-2000. Participation of groups of teachers from the same school, department, or grade. The design of this professional development program incorporated the principle of integrating laboratory experiences into the stream of instruction and the goal of providing a full range of laboratory experiences, including opportunities for students to participate in developing research questions and procedures. Teachers require a deep understanding of scientific processes in order to guide students procedures and formulation of research questions, as well as deep understanding of science concepts in order to guide them toward subject matter understanding and other learning goals. Khalic, A., and Lederman, N. (2000). A cross-age study of student understanding of the concept of homeostasis. Science Education, 77(1), 25-46. London, England: Kluwer Academic. Results of the study also confirmed the effectiveness of providing active learning opportunities. Teaching Assistant Responsibilities Arrive on time & remain in lab. Washington, DC: Brookings Institution. Generally, the body of research is weak, and the effects of teacher quality on student outcomes are small and specific to certain contexts. fessional development aligned with the curricula leads to increases in students progress toward the goals of laboratory experiences (Slotta, 2004). Studies in Science Education, 14, 33-62. All of these factors indirectly affect the academic achievement of the students. Shared teacher planning time may be a critical support for improved laboratory teaching, because of the unique nature of laboratory education. Earn CE Get Involved Advocate/Support Your Profession (2000). In B.J. Can schools narrow the black-white test score gap? 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. (2001). Designing a community of young learners: Theoretical and practical lessons.

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). This method can assist children in becoming more engaged readers and developing critical thinking abilities. little information is available on the effectiveness of these efforts.

Available at: http://www7.nationalacademies.org/bose/July_1213_2004_High_School_Labs_Meeting_Agenda.html. Teachers play a critical role in leading laboratory experiences in ways that support student learning. 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. Given the vast array of possible courses led by Teaching Assistants at UWM, their individual roles will vary considerably. Supovitz, J.A., and Turner, H.M. (2000). At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory 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).
