PHOTOSHOP LAB REPORT :: essays research papers

1.) Objective of the lab:   Ã‚  Ã‚  Ã‚  Ã‚  The objective of this lab was to make a halftone negative of a small clipart. 2.) Facilities, supplies and equipment used:   Ã‚  Ã‚  Ã‚  Ã‚  We did this in the photo lab and in the dark room. To complete this lab we needed to have a working knowledge of the camera, developer, fix and a loop. 3.) Techniques employed:   Ã‚  Ã‚  Ã‚  Ã‚  To make film of a clipart several steps must be taken. First is to turn the copy board to be parallel to the floor. Then the glass front must be unlocked and lifted. The art is then placed in the center of the board next to a gray scale. After shutting and locking the glass front the copy board is then turned to be upright facing the shutter of the camera. The aperture should be set at an F-stop of 22 at %100. The next step takes place in the dark room on the other side of the process camera. You must position the transparent plate to be locked in front of the shutter. You then press the test button or switch to check the alignment of the art on the copy board. When aligned you open the transparent plate and use the vacuum to hold the film in position on the solid plate. You then close the solid plate and press the button that controls the timer for the shutter. This exposes the film to the light from the clipart and the gray scale. When the shutter closes you rem ove the film by turning off the vacuum. Then place the film in the developer until you can see the level 4 on the gray scale. This is the desired development of the film. When there you place the film in the stop solution. After a minute or so in there you place the film in the fix. This removes all the remaining silver from the film.

Assessment of Ell Students

Running head: Assessment Assessment of English Language Learners Student Name Grand Canyon University: ESL 534 August 8 2012 With the implementation of the No Child Left behind Act of 2001, states are required to assess ELL students to determine if students are making adequate progress towards their language development goals. The purpose of the NCLB act is to challenge students to meet higher standards, close the achievement gap, and ensure that all students have the same opportunities to reach their full potential.There has been much criticism regarding the NCLB act and the high stakes testing that has developed as a result, especially when it comes to ELL students. ELL students not only have to learn required content objectives as other students, but have the challenge of learning the English language simultaneously. Students, schools, and teachers are evaluated with standardized test annually to ensure the initial goals are met.The concern that many have with standardized testing is they do not show the overall progress of the student which may lead to inaccurate results regarding a student’s language proficiency. English Language Learners are a diverse group with different languages, cultures, and backgrounds. Their language acquisition can be effected by many things including socio-economic factors and educational backgrounds. Understanding language acquisition theories can give critical insight into how assessments should be developed.Some of the popular theories of language acquisition include the threshold hypothesis, which states that a student’s language skills need to reach a critical level before students can benefit from bilingualism (Cummins, 1979) and the Critical/ Sensitive period hypothesis which states that students who are not exposed to a second language before puberty will never reach the proficiency of a native English speaker (Bailey & Heritage, 2010). According to Hakuta 2000, it takes several years for ELL students to rea ch the level of proficiency needed to learn new academic content through a second language. This theory and others hould cause educators to question the current objectives that we have for ELL students and the time frame that ELL students have for meeting those objectives. Language proficiency assessments are an important tool used to measure students’ progress as well as record their starting point. Stiggins and Chappuis 2005 argue that students make conclusions about their capability of learning based on the assessments that teachers provide. and that â€Å"feedback delivered once a year from standardized district, state, national, or international is far too infrequent and broadly focused to be helpful (Stiggins& Chappuis, 2005 p. 2). Stiggins and Chappuis believe that our current educational system places far too much emphasis on assessments and that one test does not provide an accurate measure of a schools or students success. Instead, they argue that student involved assessments are more beneficial for the student and teacher and set the student up for success. With student involved assessments student and teachers work as partners to monitor their achievement creating an environment where students feel secure and know what is expected of them and what it takes for them to meet their goals Stiggins& Chappuis, 2005).Within the last ten years there have been numerous debates centered over how or if ELL students should participate in standardized testing. Some have argued that standardized test can be biased against ELL students because they don’t take into account cultural differences in language structure. Standardized test provide only a snap shot of the learning and growth that has taken place for ELL students and is not a way to accurately monitor the progress of students. With standardized testing we shift the attention from learning and building knowledge for the future to focusing on short term results.With unrealistic goals for stan dardized testing it can be difficult to tell the difference between schools that are serving the needs of ELL students and those that are not.

A Research Study On Sickle Cell Disease - 1777 Words

This research informs the reader about Sickle cell disease. The goal is to raise awareness by describing what the disease is and where it originated. It gives advice on how to recognize signs in a crisis and how to help prevent any further symptoms. This focus uses facts from medical websites such as Web MD and Mayo Clinic. This research highlights every thing there is to know about sickle cell disease through detailed descriptions of where it comes from, how it is passed on, what it does to the body, and what can be done to help prevent it from getting really bad. Sickle cell disease is a blood disorder that is a genetic disease, which is inherited through parents. The bone marrow produces abnormal red blood cells that are a crescent shape. These red blood cells then get suck in the veins and cause many medical difficulties. This review will not investigate any personal experiences or experiences of any person. The sources mainly conclude that there are various researches trying to reveal helpful information for suffering patients. Researchers from the FSCDR administration found out that regular blood transfusions can reduce the occurrence of strokes and attacks in sickle cell patients. Regular monthly blood transfusions can help raise red blood cell counts and therefore reduce sickling and blood clots causing health complications. Further research into preventative remedies includes bone marrow transplants.
