Effective Feedback Students as Assessment Partners

Effective Feedback Students as Assessment Partners This letter will cast the light on some essential components of quality feedback as well as on the importance of feedback in primary school. What is more, it will also bring your attention to the process of achieving feedback and assessment process. In particular, it is necessary to define the quality feedback as it is identified by various scholars, and to discuss the importance of self-assessment and its role in advancing the academic achievements of students.Advertising We will write a custom assessment sample on Effective Feedback: Students as Assessment Partners specifically for you for only $16.05 $11/page Learn More So far, grading was the major tool for evaluating students’ skills and abilities. It is aimed at assessing the rate or level of students’ understanding of the subject. However, identifying the rate means pointing out students’ drawbacks and pitfalls and a failure to express a particular thought. Such system, therefore, deprives students of motivation to improve because they do not know what they should actually improve. According to Wilson (2009), the major drawback of grading tests is lack of responsiveness; grades highlight what should a student pay attention to, but not how he/she should approach the problem. You should also bear in mind that exploring the difference between quality feedback and grading assessment has led to the assumption that students’ achievements can be enhanced if using rubrics instead of scoring points (Marzano, 2009, p. 87). The scope of using appropriate scores lies in evaluating students’ achievement without interrupting the actual process of learning. Other types of assessments, like testing, do not involve a responsiveness aspect either. Smith (2009) finds it reasonable to apply for test to evaluate students’ abilities because this kind of assessment can define the way students perceive the factual knowledge. However, before introducing tests to students, teachers should be sure that a particular set of questions will involve all issues studied in class. There should be a direct correlation between test questions and learning activities and, therefore, tests should be designed for improving learning, but not for grading and decision-making. You should pay attention to Reynolds’s ideas (2009) who believes that critical evaluation and quality feedback plays an essential role in primary school education because it encourages the creation of more authentic and objective assessments (McMillan, 2011). Therefore, you should carefully select methods for assessing students in relation to learning targets and practical activities. Quality feedback, thus, should involve a multidimensional approach to evaluation. To be more precise, students should not only be objectively evaluated, but they also should also be able to critically evaluate others (Reynolds, 2009).Advertising Looking for assessment on education?

Rather, all assessment standards, and quality feedback in particular, should be directed at improving students’ achievements (Brookhart, 2008). Reference List Brookhart , S. (2008).

10 Helium Facts - Atomic Number 2 on the Periodic Table

10 Helium Facts - Atomic Number 2 on the Periodic Table Helium is the second element on the periodic table, with atomic number 2 and element symbol He. Its the lightest noble gas. Here are ten quick facts about the element helium. Check the full listing for helium if you would like additional element facts. The atomic number of helium is 2, meaning each atom of helium has two protons.  The most abundant isotope of the element has 2 neutrons. It is energetically favorable for each helium atom to have 2 electrons, which gives it a stable electron shell.Helium has the lowest melting point and boiling point of the elements, so it only exists as a gas, except under extreme conditions.  At normal pressure, helium is a liquid at absolute zero.  It must be pressurized to become a solid.Helium is the second-lightest element.  The lightest element or one with the lowest density is hydrogen. Even though hydrogen typically exists as a diatomic gas, consisting of two atoms bonded together, a single atom of helium has a higher density value. This is because the most common isotope of hydrogen has one proton and no neutrons, while each helium atom typically has two  neutrons as well as two protons.Helium is the second-most abundant element in the universe  (after hydrogen), though it is mu ch less common on Earth.  On Earth, the element is considered a nonrenewable resource.  Helium does not form compounds with other elements, while the free atom is light enough to escape Earths gravity and bleed out through the atmosphere. Some scientists are concerned we might one day run out of helium or at least make it prohibitively expensive to isolate. Helium is colorless, odorless, tasteless, non-toxic, and inert.  Of all the elements, helium is the least reactive, so it does not form compounds under ordinary conditions. In order to bond it to another element, it would need to be ionized or pressurized. Under high pressure, disodium helide (HeNa2), the clathrate-like titanate La2/3-xLi3xTiO3He, the silicate crystobalite He II (SiO2He), dihelium arsenolite (AsO6 ·2He), and NeHe2 may exist.Most helium is obtained by extracting it from natural gas.  Its uses include helium party balloons,  as a protective inert atmosphere for chemistry storage and reactions, and for cooling superconducting magnets for NMR spectrometers and MRI machines.Helium is the second-least reactive noble gas (after neon).  It is considered the real gas that most closely approximates the behavior of an ideal gas.Helium is monatomic under standard conditions. In other words, helium is found as single atoms of the element.Inhaling helium temporarily chan ges the sound of a persons voice. Although many people think inhaling helium makes a voice sound higher, it doesnt actually alter the pitch. Though helium is non-toxic, breathing it can result in asphyxiation due to oxygen deprivation. Evidence of heliums existence came from the  observation of a yellow spectral line from the sun. The name for the element comes from the Greek god of the Sun, Helios.
