Shulman, L.S. Gamoran, A., Anderson, C.W., Quiroz, P.A., Seceda, W.G., Williams, T., and Ashmann, S. (2003). Supporting classroom discussions may be particularly challenging for teachers who work with a very diverse student population in a single classroom, or those who have a different cultural background from their students (see Tobin, 2004). For example, in developing the Computers as Learning Partners science curriculum unit, Linn and colleagues researched how well models of thermodynamics at various levels of abstraction supported students learning. At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory work, and the case for laboratory . In J.M. Strategies for Effective Teaching in the Laboratory Class | CRLT They felt confident to guide their students through the same process, where there is no right answer.. Further research is needed to examine the scope and effectiveness of the many individual programs and initiatives. 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. These professionals use specialized instrumentation and techniques to analyze patients' samples, such as blood, urine, body fluids and tissue, and stool. Students were asked to survey the literature for methods to reduce aromatic nitro compounds to the corresponding amines. 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. 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.

East Lansing, MI: National Center for Research in Teacher Education. ), Internet environments for science education. 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. A Japanese high school language lab shows students' positions One theme that emerges from such research is that the content knowledge gained from undergraduate work is often superficial and not well integrated. 153-186). Learning to teach inquiry science in a technology-based environment: A case study. Journal of Science Education and Technology, 13(2), 189-206. The role of teacher in the acquisition of scientific knowledge in Secondary School Science class cannot be underestimated. However, their study was criticized for being conducted in laboratory environment (Taylor, Ntoumanis, . Journal of College Science Teaching, 33(6). Hofstein, A., and Lunetta, V.N. However, the students were surprised that methods taken from the literature did not always work. Deep disciplinary expertise is necessary to help students learn to use laboratory tools and procedures and to make observations and gather data. Between sessions, teacher participants reflected on what they were learning and applied some of it in their classrooms, following the active learning approach suggested by the research on professional development for science teachers.

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. 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).

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. Data from the 2000 National Survey of Science and Mathematics Education. McComas, W.F., and Colburn, A.I. Although no national information is available about high school teachers participation in laboratory internship programs, a recent survey found that only 1 in 10 novice elementary school teachers had participated in internship programs in which they worked directly with scientists or engineers. 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. 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. Results of the study also confirmed the effectiveness of providing active learning opportunities. The teaching profession is evolving on a regular basis, with new technology being incorporated into teaching methods and information updated regularly. Supovitz, J.A., Mayer, D.P., and Kahle, J.

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. 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). Specifically, it challenges the assumption that having a college degree in science, by itself, is sufficient to teach high school science. The web-based inquiry science environment (WISE): Scaffolding knowledge integration in the science classroom. Not a MyNAP member yet? This chapter describes some of the factors contributing to the weakness of current laboratory experiences. Literature review: The role of the teacher in inquiry-based education London, England: Kluwer Academic. 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). 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). Sanders, W.L., and Rivers, J.C. (1996). 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. The main purpose of laboratory work in science education is to provide students with conceptual and theoretical knowledge to help them learn scientific concepts, and through scientific methods, to understand the nature of science. Qualifications of the public school teacher workforce: Prevalence of out-of-field teaching 1987-88 to 1999-2000.

The functions of the laboratory teaching assistant are to provide instruction, supervision, and assistance, as required, to the students in his/her section. Linn, M.C. 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). 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 The arts and science as preparation for teaching. Teachers design and carry out an open-ended field research project, of their own choosing. ), The student laboratory and the curriculum (pp. 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.
