Goldhaber, D.D., Brewer, D.J., and Anderson, D. (1999). Hegarty-Hazel, E. (1990). Because many current science teachers have demographic backgrounds different from their students (Lee, 2002; Lynch, Kuipers, Pyke, and Szeze, in press), the ability to communicate across barriers of language and culture is. 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). 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. Implications of teachers beliefs about the nature of science: Comparisons of the beliefs of scientists, secondary science teachers, and elementary science teachers. A study package for examining and tracking changes in teachers knowledge. Paper prepared for the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. Over the course of a years worth of pedagogical preparation and field experiences, the new teachers began to reorganize their knowledge of biology according to how they thought it should be taught. Journal of Research in Science Teaching, 31, 621-637. (2004). Block scheduling is one approach schools have used to provide longer periods of time for laboratory activities and discussion. It was also clear that teachers enhanced their understanding of science subject matter specific to the lab they experienced. Improving high school science teachers capacity to lead laboratory experiences effectively is critical to advancing the educational goals of these experiences. Few professional development programs for science teachers emphasize laboratory instruction. Helping students attain the learning goals of laboratory experiences requires their teachers to have broad and deep understanding of both the processes and outcomes of scientific research. Page 111 Share Cite. Fraser and K.G. in a limited range of laboratory experiences that do not follow the principles of instructional design identified in Chapter 3. Further research is needed to inform design of professional development that can effectively support improvements in teachers laboratory instruction. 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. Qualified high school teachers will have opportunities to work and learn at the Argonne, Brookhaven, Lawrence Berkeley, Oak Ridge, and Pacific Northwest National Laboratories and at the National Renewable Energy Laboratory. Assistants show the students how to handle chemical spills, dispose of broken glassware and get rid of non-hazardous and chemical waste . At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory The mystery of good teaching: Surveying the evidence on student achievement and teachers characteristics. Portsmouth, NH: Heinemann. The Biological Sciences Curriculum Study. In a case study of his experience, this professor called for reducing science teachers class loads so they have more time to reflect on and improve their own practice. A research agenda. Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. Those who understand: Knowledge growth in teaching. The role of practical work in the teaching and learning of science. (2002). 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. 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. The poor quality of laboratory experiences of most high school students today results partly from the challenges that laboratory teaching and learning pose to school administrators. Duschl, R. (1983). Paper presented at the annual meeting of the National Association for Research in Science Teaching, April, St. Louis, MO. In C. Jencks and M. Phillips (Eds. Periodic checks indicated that the science internship helped teachers improve their understanding of [the nature of science] and [science inquiry]. Designing professional development for teachers of science and mathematics. Introduction The laboratory in the school has been defined by several authors in different ways. Results of the study also confirmed the effectiveness of providing active learning opportunities. 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). Davis, and P. Bell (Eds. 249-262). 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). 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. 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. The impact of longer term intervention on reforming the approaches to instructions in chemistry by urban teachers of physical and life sciences at the secondary school level. 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). Presentation to the Committee on High School Science Laboratories: Role and Vision, July 12-13, National Research Council, Washington, DC. Second group of factors are the environmental factors. The research described above indicates that undergraduate laboratory experiences do not integrate learning of science content and science processes in ways that lead to deep conceptual understanding of science subject matter. 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. 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). Gamoran and others studied six sites where teachers and educational researchers collaborated to reform science and mathematics teaching, focusing on teaching for understanding. 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. 7082.) Harlen, W. (2000). Bell, P. (2004). Goldhaber, D.D., and Brewer, D.J. The degree to which teachers themselves have attained the goals we speak of in this report is likely to influence their laboratory teaching and the extent to which their students progress toward these goals. Emerging issues and practices in science assessment. You're looking at OpenBook, NAP.edu's online reading room since 1999. Maienschein, J. The distinction between key ideas in teaching school physics and key ideas in the discipline of physics. Further research is needed to evaluate these and other efforts to link scientists with K-12 education. 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. Teachers need to use data drawn from conversations, observations, and previous student work to make informed decisions about how to help them move toward desired goals. (1990). Teaching Assistant Responsibilities Arrive on time & remain in lab. The study examined the relationship between professional development and teaching practice in terms of three specific instructional practices: (1) the use of technology, (2) the use of higher order instructional methods, and (3) the use of alternative assessment. The organization and structure of most high schools impede teachers and administrators ongoing learning about science instruction and the implementation of quality laboratory experiences. Does teacher certification matter? Ingersoll, R. (2003). Kennedy, M., Ball, D., McDiarmid, G.W., and Schmidt, W. (1991). Active learning opportunities focused on analysis of teaching and learning. Primary science: Taking the plunge. an increasingly important aspect of their general pedagogical knowledge. In W. Fowler (Ed. Shared teacher planning time may be a critical support for improved laboratory teaching, because of the unique nature of laboratory education. Share a link to this book page on your preferred social network or via email. (1998). Educational Evaluation and Policy Analysis, 24(2), 81-112. They knew little about how various ideas were related to each other, nor could they readily explain the overall content and character of biology. The laboratory science teacher professional development program. You choose your level of involvement based on your needs. Final report on the evaluation of the National Science Foundations Instructional Materials Development Program. Coherence (consistency with teachers goals, state standards, and assessments). To make these choices, they must be aware not only of their own capabilities, but also of students needs and readiness to engage in the various types of laboratory experiences. Among these factors, curriculum has a strong influence on teaching strategies (Weiss, Pasley, Smith, Banilower, and Heck, 2003). 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. Ferguson, R. (1998). Science Teacher (October), 40-43. He suggests that a high school physics teacher should know concepts or principles to emphasize when introducing high school students to a particular topic (p. 264). Science Education, 77(1), 25-46. 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. The changing nature of work: Implications for occupational analysis. Deep disciplinary expertise is necessary to help students learn to use laboratory tools and procedures and to make observations and gather data. (2001). The elementary level science methods course: Breeding ground of an apprehension toward science? During the school year, teachers may access kits of materials supporting laboratory experiences that use biomedical research tools. Understanding cellular respiration: An analysis of conceptual change in college biology. Henderson, A.T., and Mapp, K.L. Clark, R.L., Clough, M.P., and Berg, C.A. 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). 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). Many schools schedule eight 40- to 55-minute class periods, so that following the AAPT guidelines would allow physics teachers two preparation periods. 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. 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-. Figure 1. The paper recommend among others: . Focusing laboratory experiences on clear learning goals requires that teachers understand assessment methods so they can measure and guide their students progress toward those goals. 99-138). or use these buttons to go back to the previous chapter or skip to the next one. Science for all, including students from non-English-language backgrounds. Science Education, 88, 28-54. 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). What changes need to be made to improve laboratory experiences for high school students? However, a review of the literature five years later revealed no widespread efforts to improve laboratory education for either preservice or in-service teachers (McComas and Colburn, 1995). As already known, most of the teacher candidates carry out closeended laboratory - practices throughout their university education [14]. They also face uncertainty about how many variables students should struggle with and how much to narrow the context and procedures of the investigation. Science Educator, 12(1), 1-9. (2001). 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 . Classroom and field-based "lab work" is conceptualized as central components of (1986). Data from the 2000 National Survey of Science and Mathematics Education. DeSimone, L.M., Garet, M., Birman, B., Porter, A., and Yoon, K. (2003). In M.C. AAPT guidelines for high school physics programs. Rather, learning is an active process which goes on within the students by guiding the learning . Mathematics and science teachers reported more frequently than other teachers that job dissatisfaction was the reason they left their jobs. National Research Council. On the basis of a review of the available research, Lunetta (1998, p. 253) suggests that, for students, time should be provided for engaging students in driving questions, for team planning, for feedback about the nature and meaning of data, and for discussion of the implications of findings, and laboratory journals should provide opportunities for individual students to reflect upon and clarify their own observations, hypotheses, conceptions.. 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). A focus on deepening teachers knowledge of science or mathematics. ReviewLiterature review: The role of the teacher in inquiry-based education. Shulman, L.S. Teachers need to listen in a way that goes well beyond an immediate right or wrong judgment. In this section we describe the difficulty school administrators encounter when they try to support effective laboratory teaching. Committee on Techniques for the Enhancement of Human Performance: Occupational Analysis. A teachers academic science preparation appears to affect student science achievement generally. 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). And, among teachers who left because of job dissatisfaction, mathematics and science teachers reported more frequently than other teachers that they left because of poor administrative support (Ingersoll, 2003, p. 7). Ann Arbor, MI 48109-2218, Strategies for Effective Teaching in the Laboratory Class, 2021Regents of the University of Michigan. The. (1990). The actual crime scene processing takes place in one day and the entire project can take up to 7 depending on your schedule. Anderson, C., Sheldon, T., and Dubay, J. Most states do not regulate the quality and content of professional development required for renewal of teaching certificates (Hirsch, Koppich, and Knapp, 2001). (1994). Seeking more effective outcomes from science laboratory experiences (Grades 7-14): Six companion studies. workincluding verification workrequires deep knowledge of the specific science concepts and science processes involved in such work (Millar, 2004). 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. (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. (1994). To determine the current role of laboratory schools in the United States, the 123 existing laboratory schools were surveyed. Copyright 2023 National Academy of Sciences. Laboratory experiments A study of a much smaller sample of teachers yielded similar findings (Catley, 2004). In D.G. 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. A cross-age study of student understanding of the concept of homeostasis. Why staying ahead one chapter doesnt really work: Subject-specific pedagogy. Raleigh: Science House, North Carolina State University. It is ultimately the role of Laboratory Assistant to facilitate the safe and efficient delivery of the curriculum designed by the teacher. View our suggested citation for this chapter. Brown, A.L., and Campione, J.C. (1998). Enforcing laboratory rules . This professional development institute also incorporated ongoing opportunities for discussion and reflection. The following 10 roles are a sampling of the many ways teachers can contribute to their schools' success. Project ICAN: Inquiry, Context, and Nature of Science. Marjolein Dobber a. , Rosanne Zwart b. , Marijn Tanis a b 1. , Bert van Oers a. Teachers play a critical role in leading laboratory experiences in ways that support student learning. Providing more focused, effective, and sustained professional development activities for more science teachers requires not only substantial financial resources and knowledge of effective professional development approaches, but also a coherent, coordinated approach at the school and district level. Using questioning to guide student thinking. (2002). Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). The teaching profession is evolving on a regular basis, with new technology being incorporated into teaching methods and information updated regularly. In addition, there is little research on whether use of block scheduling influences teachers instruction or enhances student learning. What does research tell us about learning in high school science labs? These changes persisted several years after the teachers concluded their professional development experiences.. School administrators can take several approaches to providing time for this type of ongoing discussion and reflection that supports student learning during laboratory experiences. 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. Revisiting what states are doing to improve the quality of teaching: An update on patterns and trends. 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. Time constraints can also discourage teachers from the challenges of setting up and testing laboratory equipment and materials. They should advise teachers where any concerns arise regarding safety, scheduling or resourcing of Further research is needed to assess the extent to which such programs help teachers develop the knowledge and skills required to lead laboratory experiences in ways that help students master science subject matter and progress toward other science learning goals. Lunetta, V.N. Students cannot be admitted to the classroom until you arrive. The California Institute of Technology has a program to help scientists and graduate students work with teachers in elementary school classrooms in the Pasadena school district. Linn, E.A. teacher is teaching both chemistry and physics, requiring more preparation time (American Association of Physics Teachers, 2002). Educational Researcher, 27, 12-21. (1997). The Higher Education Chemistry (RSC), 5 (2), 42-51. Internet environments for science education. Teachers help their colleagues by sharing instructional resources. Washington, DC: National Academy Press. The 2000 National Survey of Science and Mathematics Education: Compendium of tables. Expertise in science alone also does not ensure that teachers will be able to anticipate which concepts will pose the greatest difficulty for students and design instruction accordingly. Google Scholar A Japanese high school language lab shows students' positions In the Seattle program, teachers attend a 13-day summer workshop in which they work closely with each other, master teachers, and program staff to develop expertise in molecular biology. Science Teacher Responsibilities: Designing, developing, and delivering quality lesson plans and curricula that adhere to national and school guidelines. 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. Darling-Hammond, L., Berry, B., and Thoreson, A. Ready to take your reading offline? Classroom assessment and the national science education standards. Millar, R., and Driver, R. (1987). Among those who had, an overwhelming majority said the experience had helped them better understand science content and improved both their teaching practice and their enthusiasm (Bayer Corporation, 2004). Finally, adequate time is essential for student learning in laboratory experiences. 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. Currently, teachers rarely provide opportunities for students to participate in formulating questions to be addressed in the laboratory. New York: Teachers College Press. However, an analysis of national survey data indicates that teachers in block schedules do not incorporate more laboratory experiences into their instruction (Smith, 2004). The functions of the laboratory teaching assistant are to provide instruction, supervision, and assistance, as required, to the students in his/her section. (1998). U.S. Department of Education. Do all student have access to laboratory experiences? It aims to support teachers to improve their teaching skills for active learning in university science laboratory courses. To lead effective laboratory experiences, science teachers should know how to use data from all of these assessment methods in order to reflect on student progress and make informed decisions about which laboratory activities and teaching approaches to change, retain, or discard (National Research Council, 2001b; Volkman and Abell, 2003). 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). 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 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). 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). Journal of Science Teacher Education, 6(2), 120-124. This method can assist children in becoming more engaged readers and developing critical thinking abilities. Cambridge, MA: National Bureau of Economic Research. American Association of Physics Teachers. Gamoran, A. These professionals use specialized instrumentation and techniques to analyze patients' samples, such as blood, urine, body fluids and tissue, and stool. Improving teachers in-service professional development in mathematics and science: The role of postsecondary institutions. 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). 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). National Center for Family and Community Connections with Schools. 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. In M.D. Chapel Hill, NC : Horizon Research. Washington, DC: National Academy Press. Typically, states require only that teachers obtain post-baccalaureate credits within a certain period of time after being hired and then earn additional credits every few years thereafter. Ann Arbor, MI: University of Michigan Physics Department. 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). Presentation to the Committee on High School Science Laboratories: Role and Vision, June 3-4, National Research Council, Washington, DC. As we have discussed, teachers face an ongoing tension between allowing students greater autonomy in the laboratory and guiding them toward accepted scientific knowledge. Washington, DC: Author. Educational Policy, 14(3), 331-356. Portsmouth, NH: Heinemann. Formulating research questions appropriate for a science classroom and leading student discussions are two important places where the interaction of the four types of knowledge is most evident. How can school organization contribute to effective laboratory teaching. (2004). The effects of professional development on science teaching practices and classroom culture. Familiarity with the evidence or principles of a complex theory does not ensure that a teacher has a sound understanding of concepts that are meaningful to high school students and that she or he will be capable of leading students to change their ideas by critiquing each others investigations as they make sense of phenomena in their everyday lives. Educational Policy, 17(5), 613-649. Chapel Hill, NC: Horizon Research. In N.M. Lambert and B.L. What types of knowledge do teachers use to engage learners in doing science?
