Education Standardize Creativity - 759 Words

Most people go through the same or similar paths throughout their high school careers. They sit in a room full of 30 or so other kids all bored out of their minds trying to listen up for when the next test will be. All the while they’re â€Å"paying attention to the teacher† they also tend to look up to the clock on a minute by minute basis excitedly waiting for either lunch or the end of the day. When either of those events happen they’ll end up leaving the classroom like a stampeding herd of cattle trying not to be the last person left in class. Then comes the test that they’ve been working on for the past week or so, and find out that they hadn’t retained nearly as much as they had thought originally. Children cannot thrive in a boring†¦show more content†¦Standardized testing should be thrown out, and replaced with more creativity. For example instead of wasting time practicing for a Shakespearian test, one could act out the play. By ac ting out the play it gives the students an understanding of how the characters felt, and of a different perspective other than that of text. While in high school one is literally told to be good listeners, and not to talk or express one’s own ideas. In some cases it’s great to be a good listener, but it’s also important to be a good communicator just the same. What would be the point of learning all the information that someone is taught throughout high school if he or she didn’t know how to effectively communicate that information to someone else. Math classes teach many formulas to all sorts of problems, but how can someone understand the formula if he or she doesn’t even know the origin in which it came from. People can’t use something that they don’t understand, nor can they create their own conclusions leaving the evolution of information at a standstill. One major downfall to the current education regime is the increasingly growing dropout rate of teens in high school. From the start of their high school careers students begin with hundreds of students from the adjacent elementary schools.

Laser Scanning Microscopy Free Essays

1. Objective To image a sample of rhodamine-doped polystyrene etched with various shapes, using a Confocal Laser Scanning Microscope and to analyse the sample topography by 2D and 3D reconstruction of the sample image. 2. We will write a custom essay sample on Laser Scanning Microscopy or any similar topic only for you Order Now Introduction This CLSM design combined the laser scanning method with the 3D detection of biological objects labeled with fluorescent markers for the first time†¦..laser scanning microscopy, the object or specimen surface is scanned point by point by a focused laser beam. The image or other characteristic of the object is then generated by an electronic system. In a scanning laser microscope detecting fluorescent light from the specimen, the depth-discriminating property of confocal scanning has been used to carry out optical slicing of a thick specimen. The recorded digital images constitute a three-dimensional raster covering a volume of the specimen. The specimen has been visualized in stereo and rotation by making look-through projections of the digital data in different directions. 3. Materials and Devices A rhodamine-doped polystyrene sample etched with different shapes mounted onto a glass slide has already been prepared. A Zeiss LSM 510 META Axiovert 200M confocal microscope is used for imaging the sample. Fig. 1 A Zeiss LSM 510 META laser scanning confocal microscope []. 4. CLSM-principles,working of the technique, Confocal Laser Scanning Microscopy is a novel optical imaging technique that merges the technology of a Laser Scanning Microscope and a Confocal Microscope resulting in high resolution images CLSM enables to form images from selected depths from within the sample (z stacks) and generate a 3D image of a specimen by stacking 2D images from successive depths []. In this technique, a laser beam is passed through an aperture and focused by an objective lens onto a small area of the specimen. The reflected light (laser light and fluorescent light from illumination of the sample) is collected by the objective lens, and passed through a pinhole which removes ‘out of focus‘light and only allows light from the plane of focus to reach the detector which is a photo multiplier tube enabled with a filter that blocks the original laser light thus allowing the detection of the excited fluorescent wavelengths alone []. The laser beam scans the specimen point by point thus resulting in the formation of the images pixel by pixel, which can be viewed on a screen [][]. Since the scanning process in a CLSM is in a point wise fashion, in order to obtain data from, the entire sample, the specimen is moved relative to the laser beam or the laser beam is guided across the sample and CLSMs are as such also referred to as point-probing scanners [][]. The advantages of this imaging technique over other techniques are numerous such as obtaining high-resolution optical images with depth selectivity, higher level of sensitivity, less invasive form of imaging, ability to acquire in-focus images from selected depths ( a process known as optical sectioning) and thereby reconstructed with a computer to obtain three-dimensional reconstructions of samples. For the study of the rhodamine-doped polystyrene sample, a 40x C-Apochromat water-based lens was used and the CLSM imaging specifications were set to a frame size of 512?512 pixels, the depth was set to 8 bit, scan direction was set to a single direction. By varying the pinhole diameter, the degree of confocality can be varied and here the pinhole was set to 1 Airy unit. Thus only the first order of the diffraction pattern reaches the detector while the higher orders are blocked, thus improves the resolution but also results in a slight decrease in brightness. Also the laser wavelength required to successfully image the rhodamine doped polystyrene sample is xxxxx []. 5. Principle of Imaging in 3 Dimensions Plan how to experimentally characterise the surface topography (height of the geometric structures) 5. Preparation of sample and Imaging and Characterisation of Surface Topography with astd errors Imaging in 3 DimensionsThis is carried out by altering the level at which the sample is observed ie by altering the plane of focus. Thus by changing this, a series of images at different positions can be produced that spans through the through the sample thickness. Thus resulting in a series of X-Y images at different Z axis positions. Therefore by optical sectioning a series of images are obtained which are then digitally reconstructed by computer softwares to give 3D representations of the sample. In this experiment, the surface topography f the rhodamine doped polystyrene sample is carried out by performing a z- stack [][]. The boundaries of the scan are set by using the focus control and marking the top and bottom of the sample. Thus between these boundaries a series of images are taken at different z- axis and a projection of the images are performed. The parameters taken for the projection are- Initial Angle of 0 °, number of projections is 64 and a Difference Angle of 6 degr ees. Data 2 D and 3 D images of a rhodamine doped polystyrene sample etched with various shapes were taken. The images show that the surface of the polystyrene sample consists of circular, triangular and square micropillars with varying heights. With the help of 3D reconstruction of the ample topography, the heights of the micropillars were calculated. A series of three z stacks were performed for each kind of micropillar (circular, square and triangular respectively) and their heights were determined. Analysis The errors associated with the measurement of the height of each micropillar has been calculated by using standard deviation method and the following bar graphs have been plotted with the error bars denoting the standard deviation. The images obtained from the of rhodamine-doped polystyrene The consequences of quenching and photobleaching are suffered in practically all forms of fluorescence microscopy, The two phenomena are distinct in that quenching is often reversible whereas photobleaching is not . Most quenching processes act to reduce the excited state lifetime and the quantum yield of the affected fluorophore. photobleaching (also termed fading) occurs when a fluorophore permanently loses the ability to fluoresce due to photon-induced chemical damage and covalent modification An important class of photobleaching events is represented by events that are photodynamic, meaning they involve the interaction of the fluorophore with a combination of light and oxygen (158-161).Reactions between fluorophores and molecular oxygen permanently destroy fluorescence and yield a free radical singlet oxygen species that can chemically modify other molecules in living cell Comparison of LSM with atomic force microscopy (AFM) in view of application to biology Confocal Laser Scanning Microscopy (CLSM) has found tremendous application in the field of biology ranging from cell biology and genetics to microbiology and developmental biology. It allows imaging thin optical sections in living and fixed specimens ranging in thickness up to 100 micrometers. advantages, including the ability to control depth of field, 3D reconstrucyion of images, non-invasive nature, enables study of both living and fixed specimens with enhanced clarity.. Additional advantages of scanning confocal microscopy include the ability to adjust magnification electronically by varying the area scanned by the laser without having to change objectives (zoom factor). CLSM has the advantage of not requiring a probe to be suspended nanometers from the surface, as in an AFM for example, where the image is obtained by scanning with a fine tip over a surface. tomic Force Microscopy (AFM) is a powerful form of scanning probe microscopy (SPM) that performs its imaging function by measuring a local property of the surface being inspected, such as its height, optical absorption, or magnetic properties. AFM employs a probe or tip that’s positioned very close to surface to get these measurements The ability to monitor this deflection allows the AFM to create an image of the sample non-destructively even if the tip is continuously in contact with the sample. To prevent the cantilever tip from damaging the surface of the sample, it is maintained at a constant angular deflection so that the force applied by the tip on the surface is also kept constant. Contact mode imaging employs a soft cantilevered beam that has a sharp tip at its end, which is brought in contact with the surface of the sample. The force between the tip and the sample causes the cantilever to deflect in accordance with Hooke’s Law, exhibiting a spring constant th The advantages of AFM include the following: 1) it generates true, 3-dimensional surface images; 2) it does not require special sample treatments that can result in the sample’s destruction or alteration; and 3) it does not require a vacuum environment in order to operate (it can operate in both air and liquid). On the other hand, itsdisadvantages include the following: it is slow in scanning an image A stand-alone atomic force microscope (AFM) has been developed, which features a large scan area and which allows operation under liquid. This system was combined with a confocal laser scanning microscope (CLSM). Information about cell structures, obtained by CLSM, can be complemented with images of the cell surface obtained with the AFM. References [1]Claxton N S, Fellers T J, Davidson M W.

A Bought Lesson Learned Essay Example For Students

A Bought Lesson Learned Essay A Bought Lesson LearnedThe moment had come for students and staff members to order and purchase school spirit attire for the 1987-1988 school term. This was avery exciting occasion my classmates and I because nothing mattered more than being able to showcase the joyous spirit for our beloved school. Mrs. Barbati, my homeroom teacher, passed out individual catalogs from which to make selections, and there were instant waves of highly motivated, but premature claims from any one student in the class as to what he or she would purchase. After she finished distributing the catalogs, Mrs. Babati enthusiastically suggested that every participate and recommended that no selections or purchases be made without the consent of a parent or guardian. Later that evening, I presented the catalog to my mother with no consideration as to her state of mind or feeling of health. She could see the energetic nature at which I appeared; yet she accepted the catalog with very little change in emotion and posture. My mother thouroughly reviewed the information, while subliminally granting a jovial tease as for me to display a sense of calmness in that she suggested that maybe such release of energy could somehow be placed towards making the purchase myself, since I had saved a few coins and dollars of my own. Suddenly, an array of dissapointment overtook me because my attempt to make a very important identity claim in the name of good ole schoolpride and spirit had just been smoke screened by the person I had grown to love more than anyone or anthing in the world. Before giving up, the episode of being dissapointed was no longer a lasting feeling; desperation and temptation were prevalent and in play. My mother drifted off into the bathroom long enough for me to ramble through one of her dresser drawers where loose change and an assortment of papered monies would occasionally be present. As I opened the drawer, there was a one hundred dollar bill gleaming to my eyes and resting in crisp form. Within seconds of seeing such amount of money, I cuffed it as if it was my own; the valued teachings of Thou Shall Not Steai posed no sense of restaint as I walked away as if nothing had ever occurred. On the day the payments were due, I went to school with a sense of honorable guilt in that I was very much ashamed of my wrongdoing because my mother had previously raised questions bout the money after discovering that it was missing; thoughts never occurred that I had taken the money without her knowing. Just minutes after the bell rang for school to start, Mrs. Barbati requested that any one student could come forward and make payments for selected merchandise. I proudly approached her desk with money and oder form in my hand so that my payment would be record. After a quick glimpse at the one hundred dollar bill, Mrs. Barbati looked at me in a manner of surprised shock because she could not grasp the idea of me, a third grade student, being trusted with such large amount of money. She posed several quick questions which suggested I had this money in my possession without parental consent or knowledge, but my strong will would not allow me to give in. After drilling me for several minutes, Mrs. Barbati later took the money in a reluctant fashion and remained firm about possible falsehood in what I had told her about my mother knowingly provided the money and granted me permission to make the payment. Later in the day, my mother made a brief stop at my school with intentions of making the payment for the merchandise that she and I had previously discussed at home.Upon arrival, Mrs. Barbati notified my mother that I had made the payment ealier in the day with the consent of a parent. After this revelation was exposed, Mrs. Barbati went on to voice her concerns and ealier doubts about my unwillingness to tell the truth about the money when briefly confronted me in the classroom. The conversation between the them came to an end, and my mother returned home home in a furious rage. She called me out with very few words expressed, and I later became the target of one of the worst whippings ever given to third grade student in disciplinary history. .u862ededa39de6f1b010d544aabee392a , .u862ededa39de6f1b010d544aabee392a .postImageUrl , .u862ededa39de6f1b010d544aabee392a .centered-text-area { min-height: 80px; position: relative; } .u862ededa39de6f1b010d544aabee392a , .u862ededa39de6f1b010d544aabee392a:hover , .u862ededa39de6f1b010d544aabee392a:visited , .u862ededa39de6f1b010d544aabee392a:active { border:0!important; } .u862ededa39de6f1b010d544aabee392a .clearfix:after { content: ""; display: table; clear: both; } .u862ededa39de6f1b010d544aabee392a { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u862ededa39de6f1b010d544aabee392a:active , .u862ededa39de6f1b010d544aabee392a:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u862ededa39de6f1b010d544aabee392a .centered-text-area { width: 100%; position: relative ; } .u862ededa39de6f1b010d544aabee392a .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u862ededa39de6f1b010d544aabee392a .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u862ededa39de6f1b010d544aabee392a .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u862ededa39de6f1b010d544aabee392a:hover .ctaButton { background-color: #34495E!important; } .u862ededa39de6f1b010d544aabee392a .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u862ededa39de6f1b010d544aabee392a .u862ededa39de6f1b010d544aabee392a-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u862ededa39de6f1b010d544aabee392a:after { content: ""; display: block; clear: both; } READ: Negro Spirituals EssayThe embarrassment and paine receiving the order less gratifying to the point that telling the truth and respect for authority and ones property became greater priorities reguardless of circumstance.
