Resource Provider. The inequities in the availability of academically prepared teachers may pose a serious challenge to minority and poor students progress toward the. Laboratory Instructors are responsible for maintaining the routine preventative maintenance of all laboratory equipment. 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). Forty-seven percent completed and returned the questionnaire. 1071 Palmer Commons The National Academies of Sciences, Engineering, and Medicine, America's Lab Report: Investigations in High School Science, http://www.bayerus.com/msms/news/facts.cfm?mode=detailandid-survey04, http://www7.nationalacademies.org/bose/July_1213_2004_High_School_Labs_Meeting_Agenda.html, http://www7.nationalacademies.org/bose/June_3-4_2004_High_School_Labs_Meeting_Agenda.html, http://epx.sagepub.com/cgi/content/abstract/17/5/613, http://www.educationnext.org/20021/50.html, http://www.sedl.org/connections/research-syntheses.html, http://www7.nationalacademies.org/bose/July_12-13_2004_High_School_Labs_Meeting_Agenda.html, http://www.nsta.org/positionstatementandpsid=16, http://www.horizon-research.com/reports/2002/2000survey/trends.php, http://www7.nationalacademies.org/bose/March_29-30_2004_High_School_Labs_Meeting_Agenda.html, http://www7.nationalacademies.org/bose/KTobin_71204_HSLabs_Mtg.pdf, http://www.nces.ed.gov/programs/coe/2004/section4/indicator24.asp, http://www.scied.science.doe.gov/scied/LSTPD/about.htm. American Educational Research Journal 35(3), 477-496. They reported that the chief function of their school was instruction, followed, in order of emphasis, by preservice teacher education, research, and inservice teacher education. (2000). 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. Anderson, C., Sheldon, T., and Dubay, J. The National Science Teachers Association takes a slightly different position, suggesting that administrators provide teachers with a competent paraprofessional. Figure 1.

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). In developing an investigation for students to pursue, teachers must consider their current level of knowledge and skills, the range of possible laboratory experiences available, and how a given experience will advance their learning. Organizational conditions that support inquiry in high school science instruction. 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. Available at: http://www.educationnext.org/20021/50.html [accessed Feb. 2005]. When asked whether they had time during the regular school week to work with colleagues on the curriculum and teaching, 69 percent of high school teachers disagreed and 4 percent had no opinion, leaving only 28 percent who agreed. A teachers academic science preparation appears to affect student science achievement generally. The role of practical work in the teaching and learning of science. Bayer facts of science education 2004: Are the nations colleges adequately preparing elementary schoolteachers of tomorrow to teach science? The program was designed in part to address weakness in science teachers understanding of the nature of science, which was documented in earlier research (Khalic and Lederman, 2000; Schwartz and Lederman, 2002). ERIC - ED213672 - Laboratory Schools: Updated or Outdated., 1981 (2003). Mahwah, NJ: Lawrence Earlbaum. (1986). The. They must consider how to clearly communicate the learning goals of the laboratory experience to their students. They need to carefully consider written work and what they observe while students engage in projects and investigations. Time constraints can also discourage teachers from the challenges of setting up and testing laboratory equipment and materials. 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. A series of studies conducted over the past several decades has shown that teachers are one of the most important factors influencing students. Teaching Assistant Responsibilities Arrive on time & remain in lab. when studying aspects of biology . London, England: Routledge. Bayer Corporation. Smith, S. (2004). 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. Laboratory training is also frequently used to develop skills necessary for more advanced study or research. little information is available on the effectiveness of these efforts.

McComas, W.F., and Colburn, A.I. (2004). Gamoran and others studied six sites where teachers and educational researchers collaborated to reform science and mathematics teaching, focusing on teaching for understanding. 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. Linn, M.C. Science Education, 85(3), 263-278. Characterizing Instructional Practices in the Laboratory: The After completion of the course, teachers classroom behaviors were videotaped and analyzed against traditional and reformed instructional strategies.

Younger workers in a variety of occupations change jobs more frequently than their older counterparts (National Research Council, 1999). Gamoran, A., Anderson, C.W., Quiroz, P.A., Seceda, W.G., Williams, T., and Ashmann, S. (2003). 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. Mahwah, NJ: Lawrence Earlbaum. Further research is needed to evaluate these and other efforts to link scientists with K-12 education. 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). Lab Safety Teacher Responsibilities - Carolina Knowledge Center School districts, teachers, and others may want to consider these examples, but further research is needed to determine their scope and effectiveness. 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). 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. Volkmann, M., and Abell, S. (2003). The teachers participated in and analyzed practical laboratory activities, studied theoretical underpinnings of the science education they were receiving, and learned about safety issues during hands-on activity. Studies focusing specifically on science teacher quality and student achievement are somewhat more conclusive. All of these factors indirectly affect the academic achievement of the students. PDF Laboratory Teaching: Implication on Students' Achievement In - ed It appears that the uneven quality of current high school laboratory experiences is due in part to the preparation of science teachers to lead these experiences. What Does a Laboratory Instructor Do? - Zippia Cambridge, MA: Harvard University Press. Education Economics, 7(3), 199-208.

At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory Washington, DC: National Academy Press. To lead laboratory experiences that incorporate ongoing student discussion and reflection and that focus on clear, attainable learning goals, teachers require pedagogical content knowledge. Journal of Science Education and Technology, 4(2), 103-126. 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. Laboratories in science education: Understanding the history and nature of science. The Biological Sciences Curriculum Study, a science curriculum development organization, has long been engaged in the preservice education of science teachers and also offers professional development for inservice teachers. As is known, it is suggested that closedended - experiments cannot contribute much to meaningful the learning of students [13]. (2004). 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. Tobin (Eds. Chemistry laboratories play an essential role in the education of undergraduate Science, Technology, Engineering, and Mathematics (STEM) and non-STEM students. Schulze (Eds. 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). In these discussions, the teacher helps students to resolve dissonances between the way they initially understood a phenomenon and the new evidence. Synergy research and knowledge integration. East Lansing, MI: National Center for Research in Teacher Education. Finally, adequate time is essential for student learning in laboratory experiences. ), Development in school finance, 1996. Full article: Teacher motivation: Definition, research development and The Role of Laboratory in Science Teaching and Learning In response to surveys conducted in the mid-1990s, teachers indicated that, among the reasons they left their positionsincluding retirement, layoffs, and family reasonsdissatisfaction was one of the most important. Leading laboratory experiences is a demanding task requiring teachers to have sophisticated knowledge of science content and process, how students learn science, assessment of students learning, and how to design instruction to support the multiple goals of science education. 4.8.

A new wave of evidenceThe impact of school, family, and community connections in student achievement. Internet environments for science education. Chapel Hill, NC: Horizon Research. Pomeroy, D. (1993). Other studies report that undergraduate laboratory work consists primarily of verification activities, with few opportunities for ongoing discussion and reflection on how scientists evaluate new knowledge (e.g., Trumbull and Kerr, 1993, cited in Windschitl, 2004). Education Next, 2(1), 50-55. (2002). U.S. Department of Energy. Available at: http://www7.nationalacademies.org/bose/June_3-4_2004_High_School_Labs_Meeting_Agenda.html [accessed May 2005]. The extent of student learning in any educational environment depends largely on the effectiveness of the instructors. (1996). Jump up to the previous page or down to the next one. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. In an ideal world, administrators would provide adequate laboratory space and time to allow students to continue investigations over several weeks or months, and they would also provide time for students to work outside regular school hours. Journal of Personnel Evaluation in Education, 11(1), 57-67. Gamoran, A. in a limited range of laboratory experiences that do not follow the principles of instructional design identified in Chapter 3. The teachers, all biology majors, could only list the courses they had taken as a way to organize their fields. (2004). Can schools narrow the black-white test score gap? The functions of the laboratory teaching assistant are to provide instruction, supervision, and assistance, as required, to the students in his/her section. 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. Committee on Classroom Assessment and the National Science Education Standards, J.M. The research comprised both quantitative and qualitative approaches. Schwartz, R., and Lederman, N. (2002). Do all student have access to laboratory experiences? Songer, C., and Mintzes, J. (2001). Hilosky, A., Sutman, F., and Schmuckler, J. Committee on Science and Mathematics Teacher Preparation, Center for Education. However, an analysis of national survey data indicates that teachers in block schedules do not incorporate more laboratory experiences into their instruction (Smith, 2004). 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. AAPT guidelines for high school physics programs. Science Education, 75, 121-133. To be successful in leading students across the range of laboratory experiences we have described, teachers must choose laboratory experiences that are appropriate at any given time. About this Course. Further research is needed to inform design of laboratory-focused teacher professional development that can support teachers in improving laboratory instruction. fessional development aligned with the curricula leads to increases in students progress toward the goals of laboratory experiences (Slotta, 2004). National Research Council. 6. (1995). Washington, DC: Author. The group employs a variety of long-term strategies, such as engaging teachers in curriculum development and adaptation, action research, and providing on-site support by lead teachers (Linn, 1997; Lederman, 2004). an increasingly important aspect of their general pedagogical knowledge. Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. Do you want to take a quick tour of the OpenBook's features? 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). Ferguson, R. (1998). In a guided-inquiry laboratory (GIL), the teacher provides the students with a question, or set of questions, and the students design an experiment to address the question(s). Examining the effects of a highly rated curriculum unit on diverse students: Results from a planning grant. Washington, DC: American Psychological Association. We do not yet know how best to develop the knowledge and skills that teachers require to lead laboratory experiences that help students master science subject matter, develop scientific reasoning skills, and attain the other goals of laboratory education. 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. 357-382). thus expanding the teaching or training role; sometimes they are excluded purposely, such as in the case of France, where teachers are only responsible for the actual instruction and the remainder of . Learning in the laboratory: Some thoughts from the literature. Science teachers behavior in the classroom is influenced by the science curriculum, educational standards, and other factors, such as time constraints and the availability of facilities and supplies. This method can assist children in becoming more engaged readers and developing critical thinking abilities. Although the time frame of the study prevented analysis of whether the teacher communities were sustained over time, the results suggest that school districts can use focused professional development as a way to create strong teaching communities with the potential to support continued improvement in laboratory teaching and learning. The institute included a blend of modeling, small group work, cooperative learning activities, and theoretical and research-based suggestions (p. 122).
