He enrolled at the University of the Free State in 1980 and obtained a BSc degree in Mathematics and Physics, as well as a Higher Education Diploma. McDiarmid, G.S., Ball, D.L., and Anderson, C.W. They surveyed a sample of 207 teachers in 30 schools, 10 districts, and 5 states to examine features of professional development and its effects on teaching practice from 1996 to 1999 (DeSimone et al., 2002). 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. 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.

In this program, faculty modeled lower-level inquiry-oriented instruction focused on short laboratory sessions with limited lecturing and no definitions of terms. High school science laboratories. Internet environments for science education. 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). Administrators who take a more flexible approach can support effective laboratory teaching by providing teachers with adequate time and space for ongoing professional development and shared lesson planning. The National Research Council (NRC) Committee on Science and Mathematics Teacher preparation stated that studies conducted over the past quarter century increasingly point to a strong correlation between student achievement in K-12 science and mathematics and the teaching quality and level of knowledge of K-12 teachers of science and mathematics (National Research Council, 2001a, p. 4). Jump up to the previous page or down to the next one. 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. (2004). 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). Project ICAN includes an intensive three-day summer orientation for science teachers followed by full-day monthly workshops from September through June, focusing on the nature of science and scientific inquiry. 100 Washtenaw Ave. School administrators have a strong influence on whether high school science teachers receive the professional development opportunities needed to develop the knowledge and skills we have identified.

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. The laboratory in science education: Foundations for the twenty-first century. Other duties include reinforcing laboratory housekeeping and safety protocol, coordinating with other engineering departments, and receiving, installing, and maintaining laboratory supplies and equipment. Trumbull, D., and Kerr, P. (1993). Atkin and J.E. (1995). (1997). The teachers, all biology majors, could only list the courses they had taken as a way to organize their fields. Current professional development for science teachers is uneven in quantity and quality and places little emphasis on laboratory teaching. National Center for Education Statistics. Washington, DC: Brookings Institution. Educational Policy, 14(3), 331-356. Is there a shortage among mathematics and science teachers? (2004). 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). 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. As is known, it is suggested that closedended - experiments cannot contribute much to meaningful the learning of students [13]. Rethinking the continuum of preparation and professional development for secondary science educators. Culturally adaptive teaching and learning science in labs. 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. Educational Evaluation and Policy Analysis, 23(1), 57-77. The traditional didactic pedagogy to which teacher candidates are exposed in university science courses equips learners with only minimal conceptual understandings of their science disciplines (Duschl, 1983; Gallagher, 1991; Pomeroy, 1993, cited in Windschitl, 2004). London, England: Routledge. It is ultimately the role of Laboratory Assistant to facilitate the safe and efficient delivery of the curriculum designed by the teacher. A new wave of evidenceThe impact of school, family, and community connections in student achievement. Among the volunteers, 97 percent said they would recommend RE-SEED to a colleague, and most said that the training, placement in schools, and support from staff had made their time well spent (Zahopoulos, 2003). There are promising examples of teacher professional development focused on laboratory experiences. 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 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. Science Teacher (October), 40-43. Journal of Research in Science Teaching, 29, 51-61. The Role of the Teacher in .

Studies focusing specifically on science teacher quality and student achievement are somewhat more conclusive. The actual crime scene processing takes place in one day and the entire project can take up to 7 depending on your schedule. (2003). NSTA position statement: Laboratory science. The role of the laboratory in science learning. (1996). 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. Journal of College Science Teaching, 33(6). 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).

Portsmouth, NH: Heinemann. During the school year, teachers may access kits of materials supporting laboratory experiences that use biomedical research tools. CrossRef Google Scholar Johnstone, A. H., & Al-Shuaili, A. What types of knowledge do teachers use to engage learners in doing science? 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). Once on the job, science teachers have few opportunities to improve their laboratory teaching. 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. Meaning making in secondary science classrooms. Harlen, W. (2001). It often consists mostly of one-day (or shorter) workshops focusing on how-to activities that are unlikely to challenge teachers beliefs about teaching and learning that support their current practice (DeSimone, Garet, Birman, Porter, and Yoon, 2003). The condition of education. Requirements for professional development of in-service science teachers differ widely from state to state. In this section, we describe the types of teacher knowledge and skills that may be required to lead a range of laboratory experiences aligned with our design principles, comparing the required skills with evidence about the current state of teachers knowledge and skills. We then present promising examples of approaches to enhancing teachers capacity to lead laboratory experiences. Science Education, 77, 261-278. 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. (1991). These school-based teacher communities, in turn, not only supported teachers in improving their teaching practices, but also helped them create new resources, such as new curricula. The inequities in the availability of academically prepared teachers may pose a serious challenge to minority and poor students progress toward the. 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. Final report on the evaluation of the National Science Foundations Instructional Materials Development Program. ), Knowledge base for the beginning teacher. Participation of groups of teachers from the same school, department, or grade. Can schools narrow the black-white test score gap? They appeared to have little understanding of the field writ large. (1995). They need to carefully consider written work and what they observe while students engage in projects and investigations. Supovitz, J.A., and Turner, H.M. (2000). Emerging issues and practices in science assessment. Available at: http://www.bayerus.com/msms/news/facts.cfm?mode=detailandid-survey04 [accessed Dec. 2004]. At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory work, and the case for laboratory . 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. In D.G. Does teacher certification matter? Some individual teachers told our committee that they did not have adequate preparation and cleanup time.

Most states do not regulate the quality and content of professional development required for renewal of teaching certificates (Hirsch, Koppich, and Knapp, 2001). Journal of Chemical Education, 75(1), 100-104. Educational Researcher, 27, 12-21. 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. Other studies have also found that most teachers do not experience sustained professional development and that they view it as ineffective (Windschitl, 2004). How do teachers work and learnspecifically related to labs. 153-186). Fulfilling the promise: Biology education in the nations schools. In chemistry laboratories at large universities, the instructors of record are typically graduate or undergraduate . The role of the laboratory in science teaching: Neglected aspects of research. Linn, M.C., Davis, E.A., and Bell, P. (2004). 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. In these discussions, the teacher helps students to resolve dissonances between the way they initially understood a phenomenon and the new evidence.
