Definition and Examples of Clustering in Composition

Definition and Examples of Clustering in Composition In composition, a discovery strategy in which the writer groups ideas in a nonlinear fashion, using lines and circles to indicate relationships. Clustering Clustering (sometimes also known as branching or mapping) is a structured technique based on the same associative principles as brainstorming and listing. Clustering is distinct, however, because it involves a slightly more developed heuristic (Buzan Buzan, 1993; Glenn et al., 2003; Sharples, 1999; Soven, 1999). Clustering procedures vary considerably, although the fundamental objective is to equip students with tools for arranging words, phrases, concepts, memories, and propositions triggered by a single stimulus (i.e., a piece of information, a topic, a provocative question, a metaphor, a visual image). As with other [invention] techniques..., clustering should first be modeled and practiced in class so students can eventually incorporate the tool into their own repertoire of invention and planning strategies.(Dana Ferris and John Hedgcock, Teaching ESL Composition: Purpose, Process, and Practice, 2nd ed. Lawrence Erlbaum, 2005) Guidelines for Teaching the Clustering Process What instructions should you give to begin this prewriting process? I have found the following both appropriate and effective:(Gabriele Lusser Rico, Clustering: A Prewriting Process, in Practical Ideas for Teaching Writing As a Process, ed. by Carol B. Olson. Diane, 1996)Tell students that they are going to use a tool that will enable them to write more easily and more powerfully, a tool similar to brainstorming.Encircle a word on the boardfor example, energyand ask students, What do you think of when you see that word? Encourage all responses. Cluster these responses, radiating outward. When they have finished giving their responses, say, See how many ideas there are floating around in your heads? Now, if you cluster all by yourself, you will have a set of connections as unique to your own mind as a thumbprint is to your thumb.Now ask students to cluster a second word for themselves. Before they begin, tell them that the clustering process should take no more than one or two minutes and that the paragraph they will write should take about eight minutes. Ask them to keep clustering until the Aha! shift, signaling that their mind is holding something they can shape into a whole. In writing, the only constraint is that they come full circle: i.e., that they do not leave the writing unfinished. Some excellent words are afraid or try or help.After they finish writing, ask students to give a title to what they have written that is suggestive of the whole. Mind-Mapping Mind-mapping is a colorful and creative method of generating, organizing, and remembering ideas. To mind-map, write your topic in the center of a blank page within a visual representation of your topic, such as a giant musical note, a sailboat, or scuba gear. If no central image comes to mind, use a box, heart, circle, or other shape. Then use various colors of ink to color-code related ideas. From the central figure draw radiating lines like the rays of the sun or branches and roots of a tree. Then, as you think of parts of the subject you wish to discuss, jot down pictures, key words, or phrases on or near these lines. Also add examples and subparts using branching lines and more images and words. If you do not already have a central focus for your essay, watch for a key phrase or image as you complete your exploration.(Diana Hacker and Betty Renshaw, Writing With a Voice, 2nd ed. Scott, Foresman, 1989) Also Known As: branching, mapping

Bio of Robert Goddard, American Rocket Scientist

Bio of Robert Goddard, American Rocket Scientist Robert Hutchings Goddard (October 5, 1882–August 10, 1945) was an influential American rocket scientist whose work shaped the history of space exploration. Yet, as far-reaching as Goddards work became, it was not acknowledged as important by the government or military for much of his life. Nevertheless, Goddard persevered, and today all rocket technologies owe him an intellectual debt. Fast Facts: Robert H. Goddard Full Name: Robert Hutchings GoddardOccupation: Engineer and rocket developerBorn: October 5, 1882 in Worcester, Massachusetts, USAParents Names: Nahum Goddard, Fannie L.

He was sickly as a child, but had a telescope and often spent time studying the sky. He eventually became interested in science, particularly the mechanics of flight. His discovery of Smithsonian magazine and articles by flight expert Samuel Pierpont Langley ignited a lifelong interest in aerodynamics. As an undergraduate, Goddard attended Worcester Polytechnic Institute, where he studied physics. He earned his physics Ph.D. at Clark University in 1911, then took a research fellowship at Princeton University the following year. He ultimately joined the faculty at Clark University as a professor of aerospace engineering and physics, a post he held much of his life. Research With Rockets Robert Goddard began writing about rockets while he was still an undergraduate. After getting his Ph.D., he focused on studying the atmosphere using rockets to lift instruments high enough to take temperature and pressure readings. His desire to study the upper atmosphere drove him to experiment with rockets as a possible delivery technology. Goddard had a hard time getting funding to pursue the work, but he eventually persuaded the Smithsonian Institution to support his research. In 1919, he wrote his first major treatise (published by the Smithsonian) called A Method of Reaching Extreme Altitudes, outlining the challenges of lifting mass high to the atmosphere and exploring how rockets could solve the problems of high-altitude studies.   Dr. Robert H. Goddard and His Rockets. NASA Marshall Space Flight Center (NASA-MSFC) Goddard experimented with a number of different rocket configurations and fuel loads, beginning with solid-rocket propellant fuel mixes in 1915. Eventually, he switched to liquid fuels, which required a redesign of the rockets he was using. He had to engineer fuel tanks, turbines, and combustion chambers that hadnt been fashioned for this kind of work. On March 16, 1926, Goddards first rocket soared up from a hill near Worcester, MA, on a 2.5-second flight that went up just over 12 meters.   That gasoline-powered rocket led to further developments in rocket flight. Goddard began working on newer and more powerful designs using bigger rockets. He had to solve problems controlling the angle and attitude of rocket flight, and also had to engineer rocket nozzles that would help to create greater thrust for the vehicle. Goddard also worked on a gyroscope system to control the stability of the rocket and devised a payload compartment to carry scientific instruments. Eventually, he created a parachute recovery system to return the rockets and payload safely to the ground. He also patented the multi-stage rocket in common use today. His 1919 paper, plus his other investigations into rocket design, are considered classics in the field. Dr. Goddard at his Launch Control Shack. NASA Headquarters - GReatest Images of NASA (NASA-HQ-GRIN) Goddard and the Press Although Goddards groundbreaking work garnered scientific interest, his early experiments were criticized by the press as being too fanciful. Notably, however, much of this press coverage contained scientific inaccuracies. The most famous example appeared on January 20, 1920, in The New York Times. The article mocked Goddards predictions that rockets might someday be able to circle the Moon and transport humans and instruments to other worlds. The Times retracted the article 49 years later. The retraction was published on July 16, 1969- the day after three astronauts landed on the Moon: Further investigation and experimentation have confirmed the findings of Isaac Newton in the 17th Century and it is now definitely established that a rocket can function in a vacuum as well as in an atmosphere. The Times regrets the error. Later Career Goddard continued his work on rockets throughout the 1920s and 30s, still fighting for recognition of the potential of his work by the U.S. government. Eventually, he moved his operations to Roswell, NM, and with financial backing from the Guggenheim family, he was able to carry out more rocket research. In 1942, Goddard and his team moved to Annapolis, Maryland, to work on jet-assisted take-off (JATO) technology.  He continually refined his designs throughout World War II, although not sharing his work with other scientists. Goddard preferred secrecy due to his concerns about patent infringement and intellectual property theft. (He repeatedly offered his services and technology, only to be rebuffed by the military and government.) Near the end of World War II and not long before his death, Goddard had a chance to see a captured German V-2 rocket and realized just how much the Germans had copied his work, despite the patents he had gained.   Death and Legacy Throughout his life, Robert H. Goddard remained on the research faculty at Clark University. After World War II, he  joined the American Rocket Society and its board of directors. However, his health was deteriorating, and he died on August 10, 1945. He was buried in Worcester, Massachusetts. Goddards wife, Esther Christine Kisk, gathered his papers after his death and worked on securing patents after Goddards death. Many of Goddards original papers containing his seminal work on rockets can be seen of the Smithsonian Institution Archives. Goddards influence and impact continues to be felt throughout our current space exploration efforts, plus those in the future. Honors Robert H. Goddard may not have been honored fully during his lifetime, but his legacy lives on in many places. NASAs Goddard Space Flight Center (GSFC) is named after him, as are several schools across the U.S. He amassed 214 patents for his work during his lifetime, with 131 being awarded after he died. There are streets and park that bear his name, and the Blue Origin makers have named a reusable launch vehicle for him. Sources â€Å"Robert Hutchings Goddard Biographical Note.
