Improvement Of Motor Skills In Physically Handicapped Children After I

Improvement Of Motor Skills In Physically Handicapped Children After Inclusion Motor abilities can be defined as innate and enduring. Motor skills, however, can be learned and developed through repetition. Combining a number of motor abilities develops these motor skills, and with practice these skills become perfected. In children, these skills are unfamiliar at first, but once used in everyday and recreational activities, they become ordinary and effortless. However, some children are born with less developed motor abilities, and some skills never become natural and effortless; these individuals are characterized as physically handicapped. The result of combining these lower-level abilities creates an inferior level of motor skills in physically handicapped children. Therefore these children will never be at quite the same level as those children with normal motor abilities. For this reason, some handicapped children are not able to participate at the same level of physical activity as their peers. Kasser, Collier, and Solava (1997) address the consequences of this lack of involvement: ?The resultant inactivity negatively affects developing children in many ways, especially their physical health? (p. 50). Kasser, et al. (1997) suggests inclusion as a solution to this issue, and mentions the positive effect that including disabled children in physical education classes has on the children's value in the eyes of their peers. In these cases when handicapped students are involved in activity classes, specialists become involved in helping the student improve their motor development. In most of these cases, the physical educator and a physical therapist work together to improve gross motor performance and fitness (Kasser, et al., 1997). The physical educator helps build upon the child's social, emotional, and motor development and brings the know-how in the area of effective teaching. On the other hand, the physical therapist focuses on the child's functional motor skills. The physical therapist also has an understanding of functional and age appropriate sport activities that will motivate the individual to take an active role in improving his or her own motor skills (Kasser, et al., 1997). This will also enhance the handicapped child's self-esteem, as well as their gross motor skills, when they see that they are participating in the classes along with their peers. In a study done by Block and Vogler (1995) on including handicapped children in physical education classes, the issue of self-concept and motivation was addressed. This study stated ?self-concept and motor performance were favorably enhanced in inclusive settings for both children with mild and moderate disabilities? (p. 41). Kasser, et al. (1997) also recognizes this, but adds that the rate of learning in handicapped individuals compared to typical students is much lower, and therefore must be considered when establishing the number of skills that are taught in that class or period of time. As an older sibling of a handicapped child, I have seen the results of what both these articles discuss. Block and Vogler (1995) discuss the concept of having the handicapped child work on a more fundamental skill as the rest of the class participates in the actual sport itself: students with varying abilities can all be accommodated in the same physical education setting? (p. 42). My younger sister was often involved in physical education classes with the rest of her peers in high school, and as they played five-on-five basketball (closed movement) she worked on dribbling and catching the ball (open movements). This is an example of establishing a sport specific motor skill. By combining fundamental movement skills, handicapped students (especially at the middle and high school level) learn sport skills and acquire the benefits associated with acquiring motor skills. There are three main benefits that are tied to these sport specific skills. The first of these benefits is the idea of motivation. By learning a socially valued and usable skill, handicapped students feel there is more purpose to what they are learning (Kasser, et al., 1997; Block and Vogler, 1995). For example, the educator and therapist could have the student using a computer program that helps them develop reaction time. An alternative would be involving the handicapped individual by teaching them in the gym with the rest of the children, allowing them to improve their reaction time via a specific sport skill. Although both of these examples don't take the

Scallop Facts

Scallop Facts Found in saltwater environments like the Atlantic Ocean, scallops are bivalved mollusks that can be found around the world. Unlike their relative the oyster, scallops are free-swimming mollusks that live inside a hinged shell. What most people recognize as a scallop is actually the creatures adductor muscle, which it uses to open and close its shell in order to propel itself through the water. There are more than 400 species of scallops; all are members of the Pectinidae family. Fast Facts: Scallops Scientific Name: PectinidaeCommon Name(s): Scallop, escallop,  fan shell,  or  comb shellBasic Animal Group:  InvertebrateSize: 1–6 inch valves (width of shell)Weight: Varies depending on speciesLifespan: Up to 20 yearsDiet:  OmnivoreHabitat:  Shallow marine habitats around the worldConservation  Status:  Varies depending on species Description Scallops are in the phylum Mollusca, a group of animals that also includes snails, sea slugs, octopuses, squid, clams, mussels, and oysters. Scallops are one of a group of mollusks known as  bivalves. These animals have two hinged shells that are formed of calcium carbonate. Scallops have anywhere from 50 to 100 eyes that line their  mantle. These eyes may be a brilliant blue color, and they allow the scallop to detect light, dark, and motion. They use their retinas to focus light, a job the cornea does in human eyes. Atlantic sea scallops can have very large shells, up to 9 inches in length. Bay scallops are smaller, growing to about 4 inches. The gender of Atlantic sea scallops can be distinguished. The females reproductive organs are red while the males are white.

Most prefer beds of seagrass amid shallow sandy bottoms, although some attach themselves to rocks or other substrates. In the United States, two kinds of scallops are sold as food. Atlantic sea scallops, the larger kind, are harvested wild from the Canadian border to the mid-Atlantic and are found in shallow open waters. Smaller bay scallops are found in estuaries and bays from New Jersey to Florida. There are large scallop populations in the Sea of Japan, off the Pacific coast from Peru to Chile, and near Ireland and New Zealand. The majority of farmed scallops are from China. Diet Scallops eat by filtering small organisms such as krill, algae, and larvae from the water they inhabit. As water enters the scallop, mucus traps plankton in the water, and then cilia move the food into the scallops mouth.   DEA PICTURE LIBRARY/De Agostini Picture Library/Getty Images Behavior Unlike other bivalves such as mussels and clams, most scallops are free-swimming. They swim by clapping their shells quickly using their  highly developed adductor muscle, forcing a jet of water past the shell hinge, propelling the scallop forward. Theyre surprisingly speedy. Scallops swim by opening and closing their shells using their powerful adductor muscle. This muscle is the round, fleshy scallop that anyone who eats seafood will instantly recognize. The adductor muscle varies in color from white to beige. The Atlantic sea scallops adductor muscle may be as big as 2 inches in diameter. Reproduction Many scallops are hermaphrodites, which means that they have both male and female sex organs. Others are only male or female. Scallops reproduce by spawning, which is when organisms release eggs and sperm into the water. Once an egg is fertilized, the young scallop is planktonic before settling to the sea floor, attaching to an object with byssal threads. Most scallop species lose this byssus as they grow and become free-swimming.​ Conservation Status There are hundreds of species of scallops; in general, they are not endangered. In fact, according to NOAA: U.S. wild-caught Atlantic sea scallop is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations. Bivalves such as scallops, however, are threatened by  ocean acidification, which affects the ability of these organisms to build strong shells. Species Scallops are marine  bivalve  mollusks of the family Pectinidae; the best-known are species  of the  genus  Pecten. The family Pectinidae includes about 50 genera and subgenera and more than 400 species which live around the world. Scallop species vary in their habitats; while some prefer coastal areas and intertidal zones, others live deep under the ocean. All scallops are bivalves, and in most species, the two valves of the shell are fan-shaped. The two valves may be ribbed or smooth or even knobbed. Scallop shells vary radically in color; some are white while others are purple, orange, red, or yellow. Scallops and Humans Scallop shells are easily recognized and have been a symbol since  ancient times. The fan-shaped shells have deep ridges, and two angular protrusions called auricles, one on either side of the shells hinge. Scallop shells range in color from drab and gray  to vivid and multihued. Scallop shells are an emblem of St. James, who was a  fisherman in Galilea before becoming an apostle. James is said to be buried at Santiago de Compostela in Spain, which became a shrine and pilgrimage site. Scallop shells mark the road to Santiago, and pilgrims often wear or carry scallop shells. The scallop shell is also the corporate symbol for the petrochemical giant Royal Dutch Shell. Scallops are also a major commercially harvested seafood; certain species (Placopecten magellanicus, Aequipecten irradians, and A. opercularis) are highly prized. The large adductor muscle is the part of the scallop that is typically cooked and eaten. Scallops are harvested around the world; the most productive scallop grounds are off the coast of Massachusetts and in the Bay of Fundy off the coast of Canada.
