Practical Work in Science: Misunderstood and Badly Used. By: Johnathan Osbourne

This article tackles the issue of practical work or experimental processes within the science teaching field. Specifically, Osborne questions the usefulness and degree to which it is used.
Most science classes are taught in a lab and are only deemed valid if a hands on activity, lab, or experiment is used in teaching the lesson. In my opinion maybe this is because we need a measurable way to assess students' understanding and without a gradable lab report, this would be difficult. This leads to the main point in Osborne's article, that to understand and appreciate science we must also understand that science in itself is rooted in ideas, sometimes as Osborne states, "crazy" ideas. Osborne observes that most students when asked to name famous scientists, names such as Galileo, Einstein, Bohr, etc., are the main ones mentioned, all of which became famously known because they had a wild, crazy idea. He lists six "postulates" which have been determined to explain what students should learn in science classes. None of which include development of ideas, which he believes should be the basis for science teaching. His stand on practical work is that it is useful, but not in the way science teachers currently use it. Practical work has become the lesson in itself, rather than part of a larger lesson, and is being taught as a skill and method that should be perfected. Because of this, room for exploration and new ideas is eliminated, shutting out the very foundations of science. Practical work, particularly lab technique and experiments should be used as a real world connection only after ideas have been developed, discussed, thought over and explored. Then, rather than teaching to master a verified and planned out lab experiment student should be hands on in developing an experiment and methods to carry out a valid experiment to provide proof or disproof of ideas. In this way, students fully understand the basis for science, and make connections between the idea and the experiment to test that idea, while learning how to develop that experiment. In this way, practical work is much more valuable than simply teaching students steps to carry out during an experiment. I find this article extremely valuable as it brings into question, are we making the most of students' time and resources. Countless times, for science labs, especially chemistry, I have gone through the steps in a lab manual and carried out the experiment without fully understanding what exactly it was I was testing until the very end, if at all. I had to follow steps, follow the proper technique, and achieve a measurable outcome or variable, which my grade was dependent upon. My observations were not really my own but graded against observations that should be

made based on what had already been done and verified before. It's frustrating and takes away from the magic and awe of science. At the end of it all, new ideas were not seen as valued nor would I have been able to design my own experiment. It begs the question, what skill are we teaching? Are we teaching students to question the world and develop ways to test those questions or are we simply teaching to follow directions to achieve a predetermined outcome? I fully believe based on my own education we are teaching the latter and should not be.
Unfortunately, teachers are subject to protocols by governments and other entities which stipulate what must be taught and to a degree, how it must be taught. I will however keep the questions from this article in mind when tackling ways to present a new lesson and developing lesson plans. Students can learn to follow a certain technique and precious time should not be devoted to achieving a certain outcome, but the bigger determination of the grade should be, are they capable of questioning the world we live in? Can they informatively and respectfully engage in discussions about those ideas? Do they have the foundation and vocabulary to do that? Can they develop and carry out a test or experiment valuable enough to produce results for those ideas? Do they comprehend what is being obtained from the data and manipulations in an experiment? These are questions that I will ask myself as I review my lesson plan to make sure I am using practical work for what it was intended for as an inclusive approach rather than simply to grade whether my students can achieve the same results as countless other before them.

This article does an excellent job of questioning the use of practical work in the classroom; about eight pages of how it is misused. However, there is only 1-2 small paragraphs concerning the benefits for lab work. Osborne does not provide any details to the invaluable uses of this tool in the manner to which some topics in science simply need to be seen rather than explained. He also does not mention the idea of varying learning styles among students and how this is affected by overuse of lab work. There is an example of questions pertaining to a lab experiment and there are suggestions for how to overcome the overuse or misuse of practical work, but there are no specific examples of how to make the lab experiment more inclusive of the lesson. Osborne points out studies which have measured students understanding of experiments in which most have found they understand only to the degree of following the steps with no real deeper comprehension of concepts, although he does list some exceptions to these studies in which the opposite was found. What he fails to do is explain why; what was the difference between the two studies or the experiments? This would be interesting to know to see if there is some common denominator. I also found it strange that most of Osborne's quotes from others and references are from the late 1990's or very early 2000's. His article was written in 2015, so I would assume it may be more relevant to include some more recent sources.

...Science Content Standards A Message from the State Board of Education and the State Superintendent of Public Instruction. In 1998 California adopted academically rigorous content standards in science. The adoption of standards in each core subject area marked a turning point in the education reform movement that began in 1983 with the report A Nation at Risk: The Imperative for Educational Reform, by the National Commission on Excellence in Education. Until then, the reform movement had focused on important but largely structural improvements, such as more instructional time, minimum course requirements for high school diplomas, and an emphasis on local planning efforts to promote efficiency and effectiveness. The desire to improve student achievement was there, but the focus on content-that is, a comprehensive, specific vision of what students actually needed to know and be able to do-was lacking. Standards are a bold initiative. Through content standards in the core subjects, California began to redefine the state’s role in public education. For the first time, the knowledge and skills that students needed to acquire were explicitly stated for the most part by grade level, although science standards at the high school level were organized by discipline. The standards are rigorous. Students who master this content are on a par with those in the best educational systems in other states and nations. The content is attainable by all students, given sufficient time, except for those...

Some runners specialize in sprints of 100 or 200 meters. Others excel at longer races of 1,500, 5,000, or even 10,000 m. It is unusual to find a runner who competes equally well in both 100-m and 10,000-m races; most runners are more comfortable running races of particular lengths. It turns out that there is a biological basis for such preferences. The muscles that move our legs contain two main types of muscle fibers: slow-twitch and fast-twitch. Slow-twitch muscle fibers can contract many times over a longer period but don’t generate a lot of quick power for the body. They perform better in endurance exercises requiring slow, steady muscle activity, such as marathons. Fast-twitch muscle fibers can contract more quickly and powerfully than slow-twitch fibers but also...

Bacteria

...microscope. Bacteria live all around us and within us. The air is filled with bacteria, and they have even entered outer space in spacecraft. Bacteria live in the deepest parts of the ocean and deep within Earth. They are in the soil, in our food, and on plants and animals. Even our bodies are home to many different kinds of bacteria. Our lives are closely intertwined with theirs, and the health of our planet depends very much on their activities. Bacterial cells are so small that scientists measure them in units called micrometers (µm). One micrometer equals a millionth of a meter (0.0000001 m or about 0.000039 in), and an average bacterium is about one micrometer long. Hundreds of thousands of bacteria would fit on a rounded dot made by a pencil. Bacteria lack a true nucleus, a feature that distinguishes them from plant and animal cells. In plants and animals the saclike nucleus carries genetic material in the form of deoxyribonucleic acid (DNA). Bacteria also have DNA but it floats within the cell, usually in a loop or coil. A tough but resilient protective shell surrounds the bacterial cell. Biologists classify all life forms as either prokaryotes or eukaryotes. Prokaryotes are simple, single-celled organisms like bacteria. They lack a defined nucleus of the sort found in plant and animal cells. More complex organisms, including all plants and animals, whose cells have a nucleus, belong to the group called eukaryotes. The word prokaryote comes from Greek words meaning “before nucleus”;...

Answers to Conceptual Sciences

...Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific hypotheses may be perfectly reasonable; they are nonscientific only because they are not falsifiable—there is no test for possible wrongness. 5 Galileo showed the falseness of Aristotle’s claim with a single experiment—dropping heavy and lightobjects from the Leaning Tower of Pisa. 6 A scientific fact is something that competent observers can observe and agree to be true; a hypothesis is an explanation or answer that is capable of being proved wrong; a law is a hypothesis that has been tested over and over and not contradicted; a theory is a synthesis of facts and well-tested hypotheses. 7 In everyday speech, a theory is the same as a hypothesis—a statement that hasn’t been tested. 8 Theories grow stronger and more precise as they evolve to include new information. 9 The term supernatural literally means “above nature.” Science works within nature, not above it. 10 They rely on subjective personal experience and do not lead to testable hypotheses.

...many ways, as a creative intellectual activity in its own right, as a light which has served to illuminate man’s place in the uni-verse, and as the source of understanding of man’s own nature” —John F. Kennedy (1917–63) The President of America The bacterium Escherichia coli INTRODUCTION AND SCOPE MICROBIOLOGY is a specialized area of biology (Gr. bios-life+ logos-to study) that concerns with the study of microbes ordinarily too small to be seen without magnification. Microorganisms are microscopic (Gr. mikros-small+ scopein-to see) and independently living cells that, like humans, live in communities. Microorganisms include a large and diverse group of microscopic organisms that exist as single cell or cell clusters (e.g., bacteria, archaea, fungi, algae, protozoa and helminths) and the viruses, which are microscopic but not cellular. While bacteria and archaea are classed as prokaryotes (Gr. pro-before+ karyon-nucleus) the fungi, algae, protozoa and helminths are eukaryotes (Gr. eu-true or good+ karyon-nucleus). Microorganisms are present everywhere on earth, which includes humans, animals, plants and other living creatures, soil,water and atmosphere. Microorganisms are relevant to all of our lives in a multitude of ways. Sometimes, the influence of microorganisms on human life is beneficial, whereas at other times, it is detrimental. For example, microorganisms are required for the production of bread, cheese, yogurt, alcohol, wine, beer, antibiotics (e.g., penicillin,...
