Participant teachers were also interviewed. (1997). ), International handbook of science education (pp. Also, you can type in a page number and press Enter to go directly to that page in the book. Note: The suggestions below were generated by a group of U-M GSIs based on their experiences teaching in a physics lab course. 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. The actual crime scene processing takes place in one day and the entire project can take up to 7 depending on your schedule. This is a culminating project for a Forensics course or unit. 100 Washtenaw Ave. How should student learning in laboratory experiences be assessed? Studies of the few schools and teachers that have implemented research-based science curricula with embedded laboratory experiences have found that engaging teachers in developing and refining the curricula and in pro-. One theme that emerges from such research is that the content knowledge gained from undergraduate work is often superficial and not well integrated. ), Constructivism in education. However, experts do not agree on which aspects of teacher qualitysuch as having an academic major in the subject taught, holding a state teaching certificate, having a certain number of years of teaching experience, or other unknown factorscontribute to their students academic achievement (Darling-Hammond, Berry, and Thoreson, 2001; Goldhaber and Brewer, 2001). 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). Internet environments for science education. (1997). (2002). 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. 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. The Biological Sciences Curriculum Study. A study of a much smaller sample of teachers yielded similar findings (Catley, 2004). Shared teacher planning time may be a critical support for improved laboratory teaching, because of the unique nature of laboratory education. We then go on to describe approaches to supporting teachers and improving their capacity to lead laboratory experiences through improvements in professional development and use of time. 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 International Journal of Science Education, 18(7), 775-790. In another approach, schools can schedule science classes for double periods to allow more time for both carrying out investigations and reflecting on the meaning of those investigations. 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.

Project ICAN: Inquiry, Context, and Nature of Science. These strategies included arranging seating to facilitate student discussion, requiring students to supply evidence to support their claims, encouraging students to explain concepts to one another, and having students work in cooperative groups. Using questioning to assess and foster student thinking. How do teachers work and learnspecifically related to labs. Prospective and practicing secondary school science teachers knowledge and beliefs about the philosophy of science. The web-based inquiry science environment (WISE): Scaffolding knowledge integration in the science classroom. 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. ), The student laboratory and the curriculum (pp. In contrast, a physicist might use mathematics to describe or represent the reflection, transmission, and absorption of light. Younger workers in a variety of occupations change jobs more frequently than their older counterparts (National Research Council, 1999). Looking inside the classroom: A study of K-12 mathematics and science education in the United States. ), Proceedings of the Conference on K-12 Outreach from University Science Departments. Educational Policy, 17(5), 613-649. Program faculty report that many teachers tend to dwell on hands-on activities with their students at the expense of linking them with the nature of science and with abilities associated with scientific inquiry. Do you enjoy reading reports from the Academies online for free? Weiss, I.R., Pasley, J.D., Smith, P.S., Banilower, E.R., and Heck, D.J. 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). Educational Evaluation and Policy Analysis, 24(2), 81-112. Collaborator. Education Next, 2(1), 50-55. Available at: http://www.educationnext.org/20021/50.html [accessed Feb. 2005]. Teaching for understanding was defined as including a focus on student thinking, attention to powerful scientific ideas, and the development of equitable classroom learning communities. A cross-age study of student understanding of the concept of homeostasis. The research team focused the curriculum on helping students understand these principles, including flow principles, rate principles, total heat flow principles, and an integration principle. Science Education, 77, 261-278. When one college physics professor taught a high school physics class, he struggled with uncertainty about how to respond to students ideas about the phenomena they encountered, particularly when their findings contradicted accepted scientific principles (Hammer, 1997). (2002). laboratory as well as for the laboratory use in science teaching. Many schools schedule eight 40- to 55-minute class periods, so that following the AAPT guidelines would allow physics teachers two preparation periods. 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. University of Michigan Physics Department: GSI training course. DeSimone, L.M., Porter, A.S., Garet, M.S., Yoon, K.S., and Birman, B. Zahopoulos, C. (2003). The available evidence indicates that the current science teaching workforce lacks the knowledge and skills required to lead a range of effective laboratory experiences. Undergraduate science students, including preservice teachers, engage. 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). In L.P. Steffe and J. Gale (Eds. 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. Promoting inquiry-based instructional practice: The longitudinal impact of professional development in the context of systemic reform. Lab's History Department, which is responsible for educating students in grades 9-12, seeks a teacher with expertise and experience teaching Modern Global or Modern World History coursework. National Research Council. The organization and structure of most high schools impede teachers and administrators ongoing learning about science instruction and the implementation of quality laboratory experiences. Educational Researcher, 15, 4-14. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. 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. Washington, DC: Author. laboratory notebooks, essays, and portfolios (Hein and Price, 1994; Gitomer and Duschl, 1998; Harlen, 2000, 2001). Science Teacher Responsibilities: Designing, developing, and delivering quality lesson plans and curricula that adhere to national and school guidelines. 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). In this approach, school administrators recognize that leadership for improved teaching and learning is distributed throughout the school and district and does not rest on traditional hierarchies. Pomeroy, D. (1993). Seattle: University of Washington, Center for the Study of Teaching and Policy. 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. The authors of the review found that, when laboratory education is available, it focuses primarily on the care and use of laboratory equipment and laboratory safety. (2000). Science Education, 77(3), 301-317. 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. In a year-long study of prospective biology teachers (Gess-Newsome and Lederman, 1993), the participants reported never having thought about the central ideas of biology or the interrelationships among the topics. 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. When students have more freedom to pose questions or to identify and carry out procedures, they require greater guidance to ensure that their laboratory activities help them to master science subject matter and progress toward the other goals of laboratory experiences. ), International handbook of science education (pp. (1997). Assistants show the students how to handle chemical spills, dispose of broken glassware and get rid of non-hazardous and chemical waste . Other studies indicate that high-quality professional development can encourage and support science teachers in leading a full range of laboratory experiences that allow students to participate actively in formulating research questions and in designing and carrying out investigations (Windschitl, 2004). Committee on Science and Mathematics Teacher Preparation, Center for Education. The Higher Education Chemistry (RSC), 5 (2), 42-51. Teaching failure in the laboratory. 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. (2001b). Hofstein, A., and Lunetta, V.N. Hein, G.E., and Price, S. (1994). Journal of Chemical Education, 75(1), 100-104. 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). A study package for examining and tracking changes in teachers knowledge. Teachers College Record, 105(3), 465-489. Tobin (Eds. Further research is needed to inform design of laboratory-focused teacher professional development that can support teachers in improving laboratory instruction. Teachers, Laboratory Attendants and Gardeners must be made to attend, at regular . Administrators allocate time, like other resources, as a way to support teachers in carrying out these routines. Currently, few teachers lead this type of sense-making discussion (Smith, Banilower, McMahon, and Weiss, 2002). The teachers skills in posing questions and leading discussions affect students ability to build meaning from their laboratory experiences. Statistical analysis report. Google Scholar Science Education, 85(3), 263-278. 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 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.

Teacher and classroom context effects on student achievement: Implications for teacher evaluation. Data from a 2000 survey of science and mathematics education indicate that most current science teachers participate infrequently in professional development activities, and that many teachers view these activities as ineffective (Hudson, McMahon, and Overstreet, 2002). 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. Effects of professional development on teachers instruction: Results from a three-year longitudinal study. The school science laboratory: Considerations of learning, technology, and scientific practice. 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. 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. 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.
