They noted constraints on laboratory learning, including poorly designed, overcrowded laboratory classrooms and inadequate preparation of science teachers. This first meeting also included a presentation about laboratory scheduling, supplies, and equipment drawn from a national survey of science teachers conducted in At the second fact-finding meeting, an architect spoke about the design of laboratory facilities, and a sociologist described how the organization of work and authority in schools may enable or constrain innovative approaches to laboratory teaching.
Two meetings included panel discussions about laboratory teaching among groups of science teachers and school administrators. Through these presentations, review of additional literature, and internal discussions, the committee was able to respond to questions 1, 5, and 6 of the charge. The agendas for each fact-finding meeting, including the guiding questions that were sent to each presenter, appear in Appendix A.
The committee recognized that the question in its charge about the increasingly interdisciplinary nature of science question 7 is important to the future of science and to high school science laboratories.
Based on our analysis of this information, the committee partially addresses this question from the perspective of how scientists conduct their work in this chapter.
However, in order to maintain our focus on the key question of student learning in laboratories, the committee did not fully address question 7. Within the short time frame of this study, the committee focused on identifying, assembling, and analyzing the limited research available on high school science laboratories and did not attempt to do the same analysis for middle school and undergraduate science laboratories.
However, this report does discuss several studies of student laboratory learning in middle school see Chapter 3 and describes undergraduate science laboratories briefly in its analysis of the preparation of high school science teachers see in Chapter 5. The committee thinks questions about the alignment of laboratory learning merit more sustained attention than was possible in this study.
During the course of our deliberations, other important questions emerged. For example, it is apparent that the scientific community is engaged in an array of efforts to strengthen teaching and learning in high school science laboratories, but little information is available on the extent Page 18 Share Cite Suggested Citation:"1 Introduction, History, and Definition of Laboratories.
As a result, we address the role of the scientific community in high school laboratories only briefly in Chapters 1 and 5.
Another issue that arose over the course of this study is laboratory safety. We became convinced that laboratory safety is critical, but we did not fully analyze safety issues, which lay outside our charge.
Finally, although engaging students in design or engineering laboratory activities appears to hold promising connections with science laboratory activities, the committee did not explore this possibility.
Although all of these issues and questions are important, taking time and energy to address them would have deterred us from a central focus on the role of high school laboratories in promoting the teaching and learning of science for all students. One important step in defining the scope of the study was to review the history of laboratories. Examining the history of laboratory education helped to illuminate persistent tensions, provided insight into approaches to be avoided in the future, and allowed the committee to more clearly frame key questions for the future.
These changing goals have affected the nature and extent of laboratory education. They believed that scientists engaged in painstaking observation of nature to identify and accumulate facts, and only very cautiously did they draw conclusions from these facts to propose new theories.
However, scientists and teachers made few efforts to teach students about these methods.
High school and undergraduate science courses, like those in history and other subjects, were taught through lectures and textbooks, followed by rote memorization and recitation Rudolph, Lecturers emphasized student knowledge of the facts, and science laboratories were not yet accepted as part of higher education.
For example, when Benjamin Silliman set up the first chemistry laboratory at Yale in , he paid rent to the college for use of the building and equipped it at his own expense Whitman, , p.
During the s, the situation changed rapidly. Influenced by the example of chemist Justus von Liebig in Germany, leading American universities embraced the German model. In this model, laboratories played a central role as the setting for faculty research and for advanced scientific study by students.
Johns Hopkins University established itself as a research institution with student laboratories. Other leading colleges and universities followed suit, and high schools—which were just being established as educational institutions—soon began to create student science laboratories as well.
The primary goal of these early high school laboratories was to prepare students for higher science education in college and university laboratories.
As demand for secondary school teachers trained in laboratory methods grew, colleges and universities began offering summer laboratory courses for teachers. In these early years, American educators emphasized the theoretical, disciplinary goals of science education in order to prepare graduates for further science education. Because of this emphasis, high schools quickly embraced a detailed list of 40 physics experiments published by Harvard instructor Edwin Hall Harvard University, The list outlined the experiments, procedures, and equipment necessary to successfully complete all 40 experiments as a condition of admission to study physics at Harvard.
Scientific supply companies began selling complete sets of the required equipment to schools and successful completion of the exercises was soon required for admission to study physics at other colleges and universities Rudolph, However, the focus on prescribing specific experiments and procedures, illustrated by the embrace of the Harvard list, limited the effectiveness of early laboratory education.
In the rush to specify laboratory experiments, procedures, and equipment, little attention had been paid to how students might learn from these experiences. Thus physics statements are synthetic, while mathematical statements are analytic. Mathematics contains hypotheses, while physics contains theories. Mathematics statements have to be only logically true, while predictions of physics statements must match observed and experimental data.
The distinction is clear-cut, but not always obvious.

For example, mathematical physics is the application of mathematics in physics. Its methods are mathematical, but its subject is physical. Every mathematical statement used for solving has a hard-to-find physical meaning.
The final mathematical solution has an easier-to-find meaning, because it is what the solver is looking for. Physics is also called "the fundamental science" because all branches of natural science like chemistry, astronomy, geology, and biology are constrained by laws of physics. For example, chemistry studies properties, structures, and reactions of matter chemistry's focus on the molecular and atomic scale distinguishes it from physics. Structures are formed because particles exert electrical forces on each other, properties include physical characteristics of given substances, and reactions are bound by laws of physics, like conservation of energy, mass, and charge.
Physics is applied in industries like engineering and medicine. Application and influence Archimedes' screw , a simple machine for lifting The application of physical laws in lifting liquids Applied physics is a general term for physics research which is intended for a particular use.
An applied physics curriculum usually contains a few classes in an applied discipline, like geology or electrical engineering. It usually differs from engineering in that an applied physicist may not be designing something in particular, but rather is using physics or conducting physics research with the aim of developing new technologies or solving a problem.
The approach is similar to that of applied mathematics. Applied physicists use physics in scientific research.
For instance, people working on accelerator physics might seek to build better particle detectors for research in theoretical physics. Physics is used heavily in engineering. For example, statics , a subfield of mechanics , is used in the building of bridges and other static structures.
The understanding and use of acoustics results in sound control and better concert halls; similarly, the use of optics creates better optical devices.
An understanding of physics makes for more realistic flight simulators , video games , and movies, and is often critical in forensic investigations.
With the standard consensus that the laws of physics are universal and do not change with time, physics can be used to study things that would ordinarily be mired in uncertainty. For example, in the study of the origin of the earth , one can reasonably model earth's mass, temperature, and rate of rotation, as a function of time allowing one to extrapolate forward or backward in time and so predict future or prior events.
It also allows for simulations in engineering that drastically speed up the development of a new technology. But there is also considerable interdisciplinarity , so many other important fields are influenced by physics e.As this happens they change into other substances.
