In addition, some researchers argue that, although professional development expends resources (time, money, supplies), it also creates new human and social resources (Gamoran et al., 2003, p. 28). One study found that schools that provide more support to new teachers, including such professional development activities as induction and mentoring, have lower turnover rates (Ingersoll, 2003, p. 8). ), Internet environments for science education.

Generally, the body of research is weak, and the effects of teacher quality on student outcomes are small and specific to certain contexts. 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.

Given the vast array of possible courses led by Teaching Assistants at UWM, their individual roles will vary considerably. (2004). The following 10 roles are a sampling of the many ways teachers can contribute to their schools' success. 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. The final section concludes that there are many barriers to improving laboratory teaching and learning in the current school environment. You choose your level of involvement based on your needs.

Some research indicates that teachers do not respond to sustained professional development by taking their new knowledge and skills to other schools, but rather by staying and creating new benefits where they are. 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. For example, teachers realized that there is no unique method called the scientific method, after comparing the methods used in different labs, such as a biochemistry lab, engineering lab, and zoos.

Introduction The laboratory in the school has been defined by several authors in different ways. Active assessment for active learning. (2004). One study indicated that significant change in teaching practice required about 80 hours of professional development (Supovitz and Turner, 2000). Science Teacher (October), 40-43.

A teacher knows how to work well as part of a team. 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).

Lee and Fradd (1998) and others observe that some scientific values and attitudes are found in most cultures (e.g., wonder, interest, diligence, persistence, imagination, respect toward nature); others are more characteristic of Western science. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. Deep disciplinary expertise is necessary to help students learn to use laboratory tools and procedures and to make observations and gather data. Active learning opportunities focused on analysis of teaching and learning. 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. For example, the teacher might use descriptive or qualitative language or images to convey concepts related to. 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. 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. Methods of assessing student learning in laboratory activities include systematically observing and evaluating students performance in specific laboratory tasks and longer term laboratory investigations. Clearly, their preservice experiences do not provide the skills and knowledge needed to select and effectively carry out laboratory experiences that are appropriate for reaching specific science learning goals for a given group of students. They also spend a week doing laboratory research with a scientist mentor at the Fred Hutchinson Center or one of several other participating public and private research institutions in Seattle. What do they contribute to science learning? While teachers play an active role in lecture-based teaching methods, the students' role is usually reduced to sitting at their desks and listening passively to their teachers, to all. In many cases teachers ranked in-service training as their least effective source of learning (Windschitl, 2004, p. 16; emphasis in original). Block scheduling is one approach schools have used to provide longer periods of time for laboratory activities and discussion. location_onUniversity of Michigan Project ICAN: Inquiry, Context, and Nature of Science.

Williams, M., Linn, M.C., Ammon, P., and Gearhart, M. (2004). In 1999-2000, 39.4 percent of all physics teachers in public high schools had neither a major nor a minor in physics, 59.9 percent of all public high school geology teachers lacked a major or minor in geology, 35.7 percent of chemistry teachers lacked a major or minor in that field, and 21.7 percent of biology teachers had neither a major nor a minor in biology (National Center for Education Statistics, 2004). 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.

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). London, England: Routledge. Loucks-Horsley, S., Love, N., Stiles, K.E., Mundry, S., and Hewson, P.W. The teachers, all biology majors, could only list the courses they had taken as a way to organize their fields.

For example, among high school teachers who had participated in professional development aimed at learning to use inquiry-oriented teaching strategies, 25 percent indicated that this professional development had little or no impact, and 48 percent reported that the professional development merely confirmed what they were already doing.

Administrators allocate time, like other resources, as a way to support teachers in carrying out these routines. 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. It examined the role of laboratory method of teaching in improving the quality of education, strategies for effective use of laboratory method and the problems facing the effective use of laboratory method in teaching science. New York: City College Workshop Center. 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. Teachers must consider how to select curriculum that integrates laboratory experiences into the stream of instruction and how to select individual laboratory activities that will fit most appropriately into their science classes.

Scientific laboratories, college and university science departments, and science museums have launched efforts to support high school science teachers in improving laboratory teaching. What can they contribute to science learning? 153-186). As we have discussed, teachers face an ongoing tension between allowing students greater autonomy in the laboratory and guiding them toward accepted scientific knowledge. Presentation to the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. They appeared to have little understanding of the field writ large. This course is developed to improve the effectiveness of laboratory classes in higher education. Science Education, 85(3), 263-278. Teachers lacking a science major may be less likely to engage students in any type of laboratory experience and may be less likely to provide more advanced laboratory experiences, such as those that engage the students in posing research questions, in formulating and revising scientific models, and in making scientific arguments. goals of laboratory experiences. A study of a much smaller sample of teachers yielded similar findings (Catley, 2004). Jump up to the previous page or down to the next one. U.S. Department of Education. 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). The school science laboratory: Historical perspectives and contexts for contemporary teaching. Enforcing laboratory rules . In a study of 100 preservice science teachers, only 20 percent reported having laboratory experiences that gave them opportunities to ask their own questions and to design their own science investigations (Windschitl, 2004). The limited quality and availability of professional development focusing on laboratory teaching is a reflection of the weaknesses in the larger system of professional development for science teachers.

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). Summer research experiences that may enhance science teachers laboratory teaching need not take place in a laboratory facility. van Zee, E., and Minstrell, J. (1997). Hegarty-Hazel, E. (1990). (1997). (2004). Mathematics and science teachers reported more frequently than other teachers that job dissatisfaction was the reason they left their jobs. Available at: http://www.nsta.org/positionstatementandpsid=16 [accessed Oct. 2004]. The teachers skills in posing questions and leading discussions also help students to effectively and accurately communicate their laboratory activities and the science sense they make from them, using appropriate language, scientific knowledge, mathematics, and other intellectual modes of communication associated with a particular science discipline. 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.
