Perhaps this is because, among scientists, decisions about the kinds of questions to be asked and the kinds of answers to be sought are often developed by the scientific community rather than by an isolated individual (Millar, 2004). The 2000 National Survey of Science and Mathematics Education: Compendium of tables. DeSimone, L.M., Garet, M., Birman, B., Porter, A., and Yoon, K. (2003). Undergraduate science students, including preservice teachers, engage. Background: Professional development opportunities for science teachers are limited in quality, availability, and scope and place little emphasis on laboratory instruction. 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. 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).

(1990). ), International handbook of science education (pp. It will show you how laboratory sessions can differ with respect to their aim and expected learning . Assessing Laboratory Learning | UNSW Teaching Staff Gateway The effects of professional development on science teaching practices and classroom culture. Gamoran, A., Anderson, C.W., Quiroz, P.A., Seceda, W.G., Williams, T., and Ashmann, S. (2003). We then present promising examples of approaches to enhancing teachers capacity to lead laboratory experiences. Specifically, it challenges the assumption that having a college degree in science, by itself, is sufficient to teach high school science. 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. This body of knowledge addressed the kind of laboratory instruction given to students, consideration of students with special needs, supportive teaching behaviors, models to engage students working in small groups, the sequencing of instruction, and modes of assessment (p. 121). This method can assist children in becoming more engaged readers and developing critical thinking abilities. Moreover, the teacher console (keyboard) is usually fitted with a tape recorder to monitoring each compartment in the class by the teacher headset and an intercom facility to enable 2-way communication between the teacher and his/her students individually. 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). Figure 1. 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). No national survey data are available to indicate whether science teachers receive adequate preparation time or assistance from trained laboratory technicians. 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 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. ), Faculty development for improving teacher preparation (pp. Life in science laboratory classrooms at the tertiary level. However, the undergraduate education of future science teachers does not currently prepare them for effective laboratory teaching. Playing this critical role requires that teachers know much more than how to set up equipment, carry out procedures, and manage students physical activities.

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). They need to carefully consider written work and what they observe while students engage in projects and investigations. Periodic checks indicated that the science internship helped teachers improve their understanding of [the nature of science] and [science inquiry]. London, England: Kluwer Academic. Smith, P.S., Banilower, E.R., McMahon, K.C., and Weiss, I.R. The final section concludes that there are many barriers to improving laboratory teaching and learning in the current school environment. 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. It was also clear that teachers enhanced their understanding of science subject matter specific to the lab they experienced. ), Constructivism in education.

At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory work, and the case for laboratory . 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. The paraprofessional would help with setup, cleanup, community contacts, searching for resources, and other types of support (National Science Teachers Association, 1990). 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. 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).

It is unclear whether these and other ad hoc efforts to provide summer research experiences reach the majority of high school science teachers. Committee on Classroom Assessment and the National Science Education Standards, J.M. 357-382). It aims to support teachers to improve their teaching skills for active learning in university science laboratory courses. There are promising examples of teacher professional development focused on laboratory experiences. The role of practical work in the teaching and learning of science. The American Association of Physics Teachers (AAPT) suggests that physics teachers should be required to teach no more than 275 instructional minutes per day. 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). 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.

Bell, P. (2004). Younger workers in a variety of occupations change jobs more frequently than their older counterparts (National Research Council, 1999). Linn, E.A. The National Science Teachers Association takes a slightly different position, suggesting that administrators provide teachers with a competent paraprofessional. Students were asked to survey the literature for methods to reduce aromatic nitro compounds to the corresponding amines. 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. Classroom and field-based "lab work" is conceptualized as central components of 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). Further research is needed to examine the scope and effectiveness of the many individual programs and initiatives. This earlier research indicated that, just as engaging students in laboratory experiences in isolation led to little or no increase in their understanding of the nature of science, engaging prospective or current science teachers in laboratory activities led to little or no increase in their understanding of the nature of science. Gamoran, A. Available at: http://www.nsta.org/positionstatementandpsid=16 [accessed Oct. 2004]. Research conducted in teacher education programs provides some evidence of the quality of preservice science education (Windschitl, 2004).

The National Survey of Science and Mathematics Education: Trends from 1977 to 2000. 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). (2003). Further research is needed to evaluate these and other efforts to link scientists with K-12 education. Full article: Teacher motivation: Definition, research development and Further research is needed to inform design of laboratory-focused teacher professional development that can support teachers in improving laboratory instruction. Block scheduling is one approach schools have used to provide longer periods of time for laboratory activities and discussion. Engaging students in analysis of data gathered in the laboratory and in developing and revising explanatory models for those data requires teachers to be familiar with students practical equipment skills and science content knowledge and be able to engage in sophisticated scientific reasoning themselves.

At this time, however, some educators have begun to question seriously the effectiveness and the role of laboratory PDF The school science laboratory: Considerations of learning, technology 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 school science laboratory: Historical perspectives and contexts for contemporary teaching. 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). Page 111 Share Cite. 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). (1990). One study found that, when laboratories were easily accessible, 14- and 15-year-old students who used the facilities during their free time reported increased interest in academics and took advanced science courses (Henderson and Mapp, 2002). (1995). One theme that emerges from such research is that the content knowledge gained from undergraduate work is often superficial and not well integrated. Philadelphia: Open University Press. McComas and Colburn (1995) established an inservice program called Laboratory Learning: An Inservice Institute, which incorporated some of the design elements that support student learning in laboratory experiences.

The design of this professional development program incorporated the principle of integrating laboratory experiences into the stream of instruction and the goal of providing a full range of laboratory experiences, including opportunities for students to participate in developing research questions and procedures. 153-186). Biology student teachers' ideas about purpose of laboratory work As is known, it is suggested that closedended - experiments cannot contribute much to meaningful the learning of students [13].

Revisiting what states are doing to improve the quality of teaching: An update on patterns and trends. Teachers play a critical role in leading laboratory experiences in ways that support student learning. Elementary School Journal, 97(4), 401-417. Teachers require a deep understanding of scientific processes in order to guide students procedures and formulation of research questions, as well as deep understanding of science concepts in order to guide them toward subject matter understanding and other learning goals. Reporting on a post-institute survey, McComas and Colburn note that a surprising number of teachers felt that the safety sessions were most important (p. 121) (no numbers were reported). 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. This is knowledge drawn from learning theory and research that helps to explain how students develop understanding of scientific ideas. Even teachers who have majored in science may be limited in their ability to lead effective laboratory experiences, because their undergraduate science preparation provided only weak knowledge of science content and included only weak laboratory experiences. Chemistry laboratories play an essential role in the education of undergraduate Science, Technology, Engineering, and Mathematics (STEM) and non-STEM students. 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). These workshops include microteaching (peer presentation) sessions. In M.D. This paper explores the role of laboratory and field-based research experiences in secondary science education by summarizing research documenting how such activities promote science learning. Educational Researcher, 15, 4-14. Journal of Research in Science Teaching, 27, 761-776. It means figuring out what students comprehend by listening to them during their discussions about science. (1997). Researchers generally agree that the teachers academic preparation in science has a positive influence on students science achievement (U.S. Department of Education, 2000; National Research Council, 2001a). The importance of pedagogical content knowledge challenges assumptions about what science teachers should know in order to help students attain the goals of laboratory experiences. Active learning opportunities focused on analysis of teaching and learning. Prospective and practicing secondary school science teachers knowledge and beliefs about the philosophy of science. Liability of Science Educators for Laboratory Safety | NSTA 1071 Palmer Commons A teachers academic science preparation appears to affect student science achievement generally. New York: Teachers College Press. 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. Switch between the Original Pages, where you can read the report as it appeared in print, and Text Pages for the web version, where you can highlight and search the text. Few professional development programs for science teachers emphasize laboratory instruction. 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 inequities in the availability of academically prepared teachers may pose a serious challenge to minority and poor students progress toward the. Emerging issues and practices in science assessment. The functions of the laboratory teaching assistant are to provide instruction, supervision, and assistance, as required, to the students in his/her section. London, England: Kluwer Academic. Davis, and P. Bell (Eds. fessional development aligned with the curricula leads to increases in students progress toward the goals of laboratory experiences (Slotta, 2004). Guiding students to formulate their own research questions and design appropriate investigations requires sophisticated knowledge in all four of the domains we have identified.

Maduabum (1992) sees a laboratory as a place where scientific exercises are conducted by the science teachers for the benefit of the students (learners). Driver, R. (1995). They must consider how to clearly communicate the learning goals of the laboratory experience to their students. 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. Paper presented at the annual meeting of the National Association for Research in Science Teaching, April, St. Louis, MO. Only 11 percent of responding teachers indicated that science teachers in their school regularly observed other science teachers.

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). 100 Washtenaw Ave. 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. laboratory notebooks, essays, and portfolios (Hein and Price, 1994; Gitomer and Duschl, 1998; Harlen, 2000, 2001). Laboratories in science education: Understanding the history and nature of science. Laboratory learning: Addressing a neglected dimension of science teacher education. 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. To lead laboratory experiences that incorporate ongoing student discussion and reflection and that focus on clear, attainable learning goals, teachers require pedagogical content knowledge. Organizational conditions that support inquiry in high school science instruction. Javonovic, J., and King, S.S. (1998). 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. Science Teacher (October), 40-43. Laboratory experiences as a part of most U.S. high school science curricula have been taken for granted for decades, but they have rarely been carefully examined.
