The Negative Effects of High-Stakes Tests Essay - 1396 Words

Visualize a standardized test taken annually by millions of students in the U.S.A. that directly affects teaching methods, school budgets, and grade promotion. Presently, millions of schools are utilizing high-stakes tests to determine these major factors. The United States expects students to perform well on standardized testing, or school districts will suffer financial consequences under the No Child Left Behind Act (Au 502). This places pressure on everyone from administrators to students in a school district. Schools worldwide are stressed to succeed on these standardized tests when they only measure a fraction of a student’s intelligence. Standardized testing must be discontinued because it negatively affects school curricula,†¦show more content†¦Currently, instructors are pressured by state education department to adjust school curricula to meet the expectations of the standardized test. Educators alter the curriculum to â€Å"match the [standardized] testâ⠂¬  (â€Å"How Standardized†). Therefore, instructors are limited and classroom instruction is focused around test preparation for the annual standardized test. Teachers are forced to abandon their creative lessons and â€Å"teach the test,† or concentrating only on the material that will be evaluated (â€Å"How Standardized†). This frequently involves taking multiple choice tests that are formatted identically to the standardized test and only memorizing facts, formulas, and items included only on the standardized tests (â€Å"How Standardized†). Even though test scores may improve, students are not learning how to think critically and perform better in other subjects that are not on the test (â€Å"How Standardized†). Instructional time is limited in the other subject areas such as science, social studies, music, and art. Instructors feel â€Å"handicapped† and plead to state officials abandon these standardized tests for the sake of th e â€Å"quality of the instruction in American schools† (Zimmerman 206). School curricula are being modified only to prepare students for a single test, not for education the students need in the future. Additionally, school teachers are facing a gargantuan amount of pressure to teach their students the information the students need toShow MoreRelatedHigh Stakes Testing Is An Educational Strategy976 Words   |  4 PagesHigh-stakes testing is an educational strategy that affects students, teachers, and society as a whole.

1. Give a field-based example of two of the following: positive reinforcement, negative reinforcement, punishment, or extinction. In special education classroom, positive reinforcement is applicable when students transit from activities through following instructions as provided and avoiding any form of distraction as well as maintaining a reasonable level of noise in whichever circumstance. Observation all these guarantee students a ticket. A minimum of 30 tickets a week guarantees them candy from their teacher. This is seen a motivation to the students hence they strive to receive the ticket.

Nearing the end of the video, when another student is answering a question, Kira turns around to see if people are laughing at her. 4. Nigel s problem behavior includes cursing, making derogatory comments toward other students, yelling, spitting, and shoving chairs. Discuss the type of a measurement system you would use to collect data on Nigel s problem behaviors and explain your answer. To understand Nigel’s behavioral challenges, it is imperative to collect information about his behavior before the interview (Crone and Horner, 2013). Information and questions to be asked during the interviews must be those who seek to understand the cause, consequences associated with the behavior, frequency of the problems, timing and the some of the intervention strategies that have been explored. It is with the hope that Nigel opens up to during the interview to provide much information that may help find a solution to the challenges faced and further understanding the problem. The behavioral challenge can be a problem emanating from the school circles or home. If for unknown reason Nigel is not able to provide much information, direct observation will be ideal.

Introduction Ultrasonic machining is a non-traditional machining process. USM is grouped under the mechanical group NTM processes. Fig. 9. 2. 1 briefly depicts the USM process. Force, F Slurry of abrasive and water Horn Vibration frequency f ~ 19 – 25 kHz Amplitude, a ~ 10 – 50 ? m Tool Work Fig. 9. 2. 1 The USM process In ultrasonic machining, a tool of desired shape vibrates at an ultrasonic frequency (19 ~ 25 kHz) with an amplitude of around 15 – 50 ? over the workpiece. Generally the tool is pressed downward with a feed force, F. Between the tool and workpiece, the machining zone is flooded with hard abrasive particles generally in the form of a water based slurry. As the tool vibrates over the workpiece, the abrasive particles act as the indenters and indent both the work material and the tool. The abrasive particles, as they indent, the work material, would remove the same, particularly if the work material is brittle, due to crack initiation, propagation and brittle fracture of the Version 2 ME, IIT Kharagpur aterial. Hence, USM is mainly used for machining brittle materials {which are poor conductors of electricity and thus cannot be processed by Electrochemical and Electro-discharge machining (ECM and ED)}. 2. Mechanisms of Material Removal in USM and its modelling As has been mentioned earlier, USM is generally used for machining brittle work material. Material removal primarily occurs due to the indentation of the hard abrasive grits on the brittle work material. As the tool vibrates, it leads to indentation of the abrasive grits. During indentation, due to Hertzian contact stresses, cracks would develop just below the contact site, then as indentation progresses the cracks would propagate due to increase in stress and ultimately lead to brittle fracture of the work material under each individual interaction site between the abrasive grits and the workpiece. The tool material should be such that indentation by the abrasive grits does not lead to brittle failure. Thus the tools are made of tough, strong and ductile materials like steel, stainless steel and other ductile metallic alloys. Other than this brittle failure of the work material due to indentation some material removal may occur due to free flowing impact of the abrasives against the work material and related solid-solid impact erosion, but it is estimated to be rather insignificant. Thus, in the current model, material removal would be assumed to take place only due to impact of abrasives between tool and workpiece, followed by indentation and brittle fracture of the workpiece. The model does consider the deformation of the tool. In the current model, all the abrasives are considered to be identical in shape and size. An abrasive particle is considered to be spherical but with local spherical bulges as shown in Fig. 9. 2. 2. The abrasive particles are characterised by the average grit diameter, dg. It is further assumed that the local spherical bulges have a uniform diameter, db and which is related to the grit diameter by db = ? dg2. Thus an abrasive is characterised by ? and dg. db db db db dg Fig. 9. 2. 2 Schematic representation of abrasive grit Version 2 ME, IIT Kharagpur During indentation by the abrasive grit onto the workpiece and the tool, the local spherical bulges contact the surfaces and the indentation process is characterised by db rather than by dg.

Tool db abrasive grit db Work A B db 2x C D ?w Hemispherical material removed due to brittle Fig. 9. 2. 3 Interaction between grit and workpiece and tool As the indentation proceeds, the contact zone between the abrasive grit and workpiece is established and the same grows. The contact zone is circular in nature and is characterised by its diameter ‘2x’. At full indentation, the indentation depth in the work material is characterised by ? w. Due to the indentation, as the work material is brittle, brittle fracture takes place leading to hemi-spherical fracture of diameter ‘2x’ under the contact zone. Therefore material removal per abrasive grit is given as 2 ? w = ? x 3 3 Now from Fig. 9. 2. 3 AB 2 = AC 2 + BC 2 ? db ? ?d ? ? ? = ? b ? ? w ? + x2 ? 2 ? ? 2 ? 2 x = db? w neglecting ? w2 as ? w How to cite Non Conventional Machine, Papers
