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).

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). It may be useful, however, to begin . Millar, R. (2004). Medical Laboratory Professionals: Who's Who in the Lab No national survey data are available to indicate whether science teachers receive adequate preparation time or assistance from trained laboratory technicians. 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. Science educators, school administrators, policy makers, and parents will all benefit from a better understanding of the need for laboratory experiences to be an integral part of the science curriculumand how that can be accomplished. These workshops include microteaching (peer presentation) sessions. The final section concludes that there are many barriers to improving laboratory teaching and learning in the current school environment. The contents of the institute were developed on the basis of in-depth field interviews and literature reviews to tap the practical knowledge of experienced science teachers.

Cognition and Instruction, 15(4), 485-529. For example, Western science promotes a critical and questioning stance, and these values and attitudes may be discontinuous with the norms of cultures that favor cooperation, social and emotional support, consensus building, and acceptance of the authority (p. 470). 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).

However, the students were surprised that methods taken from the literature did not always work. 1 Introduction, History, and Definition of Laboratories, 3 Laboratory Experiences and Student Learning, 5 Teacher and School Readiness for Laboratory Experiences, 7 Laboratory Experiences for the 21st Century, APPENDIX A Agendas of Fact-Finding Meetings, APPENDIX B Biographical Sketches of Committee Members and Staff. (1990). (2002). laboratory notebooks, essays, and portfolios (Hein and Price, 1994; Gitomer and Duschl, 1998; Harlen, 2000, 2001). The organization and structure of most high schools impede teachers and administrators ongoing learning about science instruction and the implementation of quality laboratory experiences. Is laboratory-based instruction in beginning college-level chemistry worth the effort and expense? Pedagogical content knowledge can help teachers and curriculum developers identify attainable science learning goals, an essential step toward designing laboratory experiences with clear learning goals in mind. Review of Educational Research, 52 (2), 201-217. To succeed at it and ask the types of higher level and cognitively based questions that appear to support student learning, teachers must have considerable science content knowledge and science teaching experience (McDiarmid, Ball, and Anderson, 1989; Chaney, 1995; Sanders and Rivers, 1996; Hammer, 1997). School districts, teachers, and others may want to consider these examples, but further research is needed to determine their scope and effectiveness. in a limited range of laboratory experiences that do not follow the principles of instructional design identified in Chapter 3. 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. (71) $4.50. Pedagogical content knowledge may include knowing what theories of natural phenomena students may hold and how their ideas may differ from scientific explanations, knowledge of the ideas appropriate for children to explore at different ages, and knowledge of ideas that are prerequisites for their understanding of target concepts. 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). 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. Teachers require deep conceptual knowledge of a science discipline not only to lead laboratory experiences that are designed according to the research, but also to lead a full range of laboratory experiences reflecting the range of activities of scientists (see Chapter 1). The institute included a blend of modeling, small group work, cooperative learning activities, and theoretical and research-based suggestions (p. 122). The literature provides an overview of a range of factors motivating and demotivating pre-service and in-service teachers, and the role teacher motivation plays in possible links with other areas. Deng (2001) describes pedagogical content knowledge for science teachers as an understanding of key scientific concepts that is somewhat different from that of a scientist. Large majorities of students indicated that the program had increased their interest in science, while large majorities of teachers said they would recommend the program to other teachers and that the volunteers had had a beneficial effect on their science teaching. Journal of Research in Science Teaching, 27, 761-776. 6. Given the vast array of possible courses led by Teaching Assistants at UWM, their individual roles will vary considerably. 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.

School administrators play a critical role in supporting the successful integration of laboratory experiences in high school science by providing improved approaches to professional development and adequate time for teacher planning and implementation of laboratory experiences.

The available evidence indicates that the current science teaching workforce lacks the knowledge and skills required to lead a range of effective laboratory experiences. Atkin and J.E. AAPT guidelines for high school physics programs. Their previous, closely prescribed laboratory experiences had not helped them to understand that there are many different ways to effect a particular chemical transformation. Catley, K.

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). 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). [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.

H., & Al-Shuaili, A. This course is developed to improve the effectiveness of laboratory classes in higher 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).
