9 Free and Effective Classroom Rewards
9 Free and Effective Classroom Rewards Its no secret that schools only provide the bare minimum, so teachers often need to dip into their already shallow pockets in to supplement what the school provides in the classroom. Material rewards are one easy place where we can cut corners and still remain effective educators. You really dont need to spend your money on candy, toys, stickers, and other little goodies to extrinsically motivate, reward, and recognize your students good behavior. Emphasize intrinsic motivation and teach that learning and good behavior are rewards unto themselves. Your students will rise to your heightened expectations.à Easy, Free Rewards for Your Classroom Save yourself the trouble and consider some of the free ways you can give your students a meaningful thumbs up when they do something right. Lunch Bunchà Recognize a well-behaved table group by inviting them to Lunch Bunch with the teacher. The chosen kids bring their own lunches and eat in the classroom together with you. If you have a TV, find some cartoons to watch. Or, have the kids bring their favorite CDs from home to listen to during lunch (check the lyrics first!). They can also play games when they finish eating. The children feel special because they get to stay inside and you may even find that you enjoy this unique, low-key time with the kids as much as they do. Longer Recessà This is a great one because it doesnt have to involve extra time from you. If possible, reward a child by letting them stay outside and play until a later bell. For example, after my third graders come in, the fourth graders get to play about 10 more minutes. So, I can reward a student by letting them stay out until the fourth grade bell. You may need to double-check with yard duty supervisors before doing this. Also, you probably wont want to use this one all the time. The kids do miss some instructional time and you are relying on the supervisors to help you out. Special Seatsà Reward a well-behaved (or much-improved) child by letting them work at the teachers desk for an entire day. Or, you can set up a special seat on the rug and let chosen students have a chance to sit there during story time. This free reward is zero hassle for you and quite a thrill for the kids! Whole-Group Rewardsà Let individual students earn points towards a whole class reward. This works especially well for students who crave attention because they will earn positive attention from the whole class for their good behavior. For example, the student can earn a table point for their table group, or a few marbles for the class marble jar. This helps difficult students feel like a real part of the group and it provides for a little positive peer pressure to keep them performing well. Read-In Party Stay away from popcorn parties that require extra money and preparation from you. Tell the kids that they can wear pajamas to school that day (discuss appropriate attire, first!). They can also bring their favorite stuffed animal and a pillow. Use the day to celebrate the joys of reading. The kids get to lounge around the room for part of the day, reading, relaxing, and savoring the joy of books. You can also add in other literary activities for a rewarding day that sends a clear message to the students: Reading is Fun! Afternoon of Art and Musicà Art and music are worthy academic subjects. But, if youre like most time-strapped teachers, you cant fit enough of them into the school day. Motivate your class with this simple reward. Let the class listen to music while they work on an art project. Theyll love it and so will you! Good Phone Call Home Why do phone calls home always have to be negative? Set this standard on its head by letting parents and guardians know how great their child is doing in your class. Most students will work really hard to get this kind of individualized recognition that will make a big difference at home. This is also a wonderful opportunity to solidify your relationship with parents. They want to know that you love their child and this is an easy way to make everyone happy. Help in Another Classà This is a great one for reinforcing academic content and building self-esteem in kids who really need it. Its hard to implement in kindergarten and first grade classes, but with other grades, it works great. Recognize a worthy student by letting them help out in a lower grade for awhile. Use your professional judgment to make it work in your classroom and school environment. Hand Stamp Dont get stuck on costly and consumable stickers. Use the simple ink stamps that you already have to let a student know that they are A-okay! Simply stamp your sign of approval on the back of the childs hand. You may want to clear this with parents first, since they might not appreciate ink on their kids hand. It may sound too good to be true, but if you dont introduce material rewards in the first place, your students will never miss them. In elementary school, children are so eager to please and so pleased to receive any little special recognition. They really will bend over backward for these types of rewards that dont cost you a penny! Edited byà Janelle Cox

Before we move to our next guide, how to write a cause and effect essay on evolutionary biology, take a look at the sample below, which has been written on one of the topics above: Cause and Effect Sample Essay: 7 Scientific Theories that Debunk Charles Darwinââ¬â¢s Evolutionary Theories Before the 1800s, scientists believed that the world we live in was created by a Master Designer, i.e. God. These scientists were hard workers and dedicated their life to researching and finding scientific facts about the origin of species. However, after the 1900s, philosophers who were rich and powerful, and had influence on society, suppressed those scientific endeavors in order to make their own hypotheses, just to make a name for themselves. William Paley, best known for his Natural Theology, explained that when we see the world, its complexity and how it works, it is clear that there is a Master Designer who has created this masterpiece. In fact, the ââ¬Å"Argument of Designâ⬠states that it is unwise, and in some ways, foolish to think that anything at all might come into existence on its own. For example, if we see a watch, we know that itââ¬â¢s been crafted by someone whoââ¬â¢s an expert in his/her field. The same goes for the universe; whoever made it must be a master at his craft. Itââ¬â¢s a remarkable fact that Charles Darwinââ¬â¢s Evolution Theory was completely debunked even before it was published in his book, ââ¬Å"The Origin of Speciesâ⬠. Carl Linn, one of the earnest creationists at the time, classified numerous species and during his scientific voyage, did not see any proof of ââ¬Ëhalfway speciesââ¬â¢. This is why he concluded that there were no crossover species, since every form of species are distinct and varied, even though there can be sub-species. However, he still maintained that it was impossible to have halfway species. The First Law of Thermodynamics is one of the most remarkable and highly respected theories today about the origins of the universe. This theory talks about the law of conservation of energy and how, no matter what size or shape, the amount of energy in a particular matter stays the same. This law clearly debunks several evolutionary theories that Charles Darwin had proposed ââ¬â without scientific facts, it might be noted. The Second Law of Thermodynamics states the same and completely puts the basics of the evolutionary theory to rest, which is: simple evolves into complex. In the law of entropy, in plain words, everything runs down, wears out and is reduced to pieces. One of the most well-authenticated discoveries that also discredit the Evolution Theory is the discovery of a human skeleton in the French Caribbean island of Guadeloupe. This human skeleton dates back to 28 million years ââ¬â estimated by modern geologists by determining the age of a slab of limestone, in which the skeleton was found. Modern human skeletons have also been found in the depths of the strata. Mendel was a great scientist and a creationist as well. For several years, he bred garden peas and did multiple researches to study the results of crossing various breeds. His work was completed in about eight years and when he revealed his findings, it was distributed among 120 renowned libraries around the world. However, his journal was rejected by the Scientific Society because it, in fact, went against the Evolutionary Theory. In conclusion, his work laid the foundation of modern genetics and revealed that there is a barrier between species that doesnââ¬â¢t allow them to transmute with one another. It was in the 1900s, when his research was discovered again and changed the world of modern genetics. Louis Pasteur was another great scientist who disproved the evolutionary basis: the spontaneous generation theory. This theory states that all living things came into existence from a nonliving material. The evidence behind this was that when a pile of clothes were to remain in a corner for a long time, they would breed mice! However, the reality was that mice would gather around that pile and nest in that place for comfort, warmth and perhaps, to feast on the clothes. Lamarckism, one of the strongest foundations of evolutionary theory, was also disproved by a German scientist, August Friedrich Leopold Weismann. To disprove ââ¬Å"the inheritance of acquired characteristicsâ⬠, he conducted an experiment on 901 young white mice by cutting off their tails. He did this 19 times (in every successive generation). However, each successive generation was born with a full-length tail. Yet, modern evolutionists still teach Lamarck today, in this modern day and age. Another fact that circumcision of Jewish people doesnââ¬â¢t affect growth on the foreskin put the theory of evolution into question and the legacy of Charles Darwin himself as well. There are a plethora of scientific facts that disprove evolutionary biology and point out that there is a Master Designer who has created this complex world we live in. Despite relying relentlessly on hypothesis with no scientific evidence or proof, our generation still studies evolutionary biology based on the origin of species that we see and perceive. This is utterly wrong and should be done away with completely ââ¬â so that people can have a broader perspective in general and their researches, along with scientific facts they gather, lead to much more. As promised, you now have a sample essay which will assist you in writing an exceptional cause and effect essay on evolutionary biology. Letââ¬â¢s head on to our third and final guide, how to write a cause and effect essay on evolutionary biology. References: Harvey, P. H., Pagel, M. D. (1991).

Hospitality Careers Research Paper Example | Topics and Well Written Essays - 1250 words
Hospitality Careers - Research Paper Example Subsequently, in the food and beverage industry, positions or rather career options for banquet manager, beverage manager, catering manager, dining room manager, general manager (fullservice), general manager (quick service), human resources manager, kitchen manager and public relations manager among others can be offered, as illustrated in the career website of the National Restaurant Association (National Restaurant Association, 2013). As can be apparently observed from the above list presented for the management careers offered in the lodging and the food and beverage industries are quite vivid in nature. Moreover, both these industries are observed to deliver adequate training assistance to the management professionals as well as fresh graduates that have evidently widened the scope for future development among the employees. Therefore, it can be affirmed that these industries not only reward sufficient scope of career building to the management professionals, but also delivers d ue assistance in personality and professional development of these personnel. 2. Compare and contrast the differences between the General Management (GM) positions within the two (2) industries. Companies in the lodging industry fundamentally need to perform various functions of hospitality services along with providing travel assistance to its customers. Apparently, the role of a General Manager (GM) in lodging industry is quite challenging as the personnel will have to manage the aspects of customer satisfaction, quality of services and regular costs simultaneously with proficient skills and understanding. The GM in lodging industry is also responsible for performing other day to day operations in the business such as accounting for regular transactions, managing the staff and their payroll, handling customer complaints and requests, as well as looking after the efficient use of resources. Being in a role which benefits with the scope of regular interaction with the employees and the customers, the GM is also liable to motivate the employees and make sure that the customers are satisfied with the lodging services delivered by the industry (American Hotel & Lodging Association, 2013). On the other hand, the role of GMs in food and beverage industry may be considered as more complex than that observed in the lodging industry, owing to the additional responsibilities of bakery, food quality regulatory norms adherence and healthcare interventions. Unlike the GMs appointed in the lodging industry, GMs in the food and beverage industry are responsible to prepare reports regarding the food safety measures taken by the staff when cooking and serving the customers accordingly. The GM in food and beverage industry also needs to ensure that at every stage of the operations, laws and regulations concerning health of the customers and the maintenance of quality foods are adhered. Additionally, GMs in the food and beverage industry also share some common responsibilities such as motivating and managing the regular staff members,

Another mode of transmission is through injections in which people share infected needles and syringes, especially those who abuse drugs. The shared materials often contain blood samples of previous users and the blood is injected into another personââ¬â¢s system (Public Health 1). Transfusion of contaminated blood, though this is controlled by screening blood products before use to minimize the risk, is another mode of the infectionââ¬â¢s transmission. Other medical processes such as organ transplant may also transmit HIV but prior screening reduces recipientsââ¬â¢ vulnerabilities. Previous infections by sexually transmitted infections like gonorrhea and syphilis among other sexually transmitted infections increases a personââ¬â¢s risk of contracting HIV. Lastly, transmission can occur in health care settings when one encounter contaminated fluids or accidental injury by contaminated objects. The virus does not however spread through casual contact like shaking hands, toilet seats, and sharing towels as well as contact with saliva unless it is contaminated with blood (NHS Choices 1; Public Health

Negotiation beforehand Essay Example for Free
Negotiation beforehand Essay You ought to master the art, in a negotiation, of raising the interests of both parties and end up with a lasting common pact. Why selected: Negotiations rooted in self-centered positions often injure the relationship of both parties and are incapable of reaching good agreements. I recall a friend who lost his chance of landing a job because of his tactlessness. Application to a business or personal situation: A couple of weeks ago, a friend had lost a big time prospective employer when he haggled with him over his desired monthly salary, asking a highly competitive one despite being a fresh graduate. What added fuel to the dispute was his provoking voice that possessed an air of domineering insistence. Action steps: The situation above is best addressed by efficiently doing the following: 1. Build a long-lasting relationship with the other party by offering a wise deal. 2. Set aside personal involvement with any issues and try to look over the other sideââ¬â¢s viewpoint. 3. Do not counteract emotional outbursts with another raging flow of emotions. 4. Identify the partiesââ¬â¢ interests, not their positions as it would undermine the other in the process. 5. Lay down a wide array of alternatives, sit, and pick the best choice to settle issues once and for all. 6. Approach the issue as a common search and decide on the best objective criteria for it. 7. Establish ground rules in negotiation beforehand to have a pre-emptive measure against dirty tricks the other party may later employ (Glaser). Reference: Glaser, Tanya.

The Only Fish I Wanted To Catch :: essays research papers
The Only Fish I Wanted To Catch A sensation of astounding warmth enshrouded my mind and body as I blankly stared out on to the choppy lake. I realized that the blinding sun was sure to burn me by the end of the day. I was completely clueless as to where the day would take me. At first I was a little apprehensive about climbing into the small rowboat and heading out there for the entire day. What if I didnââ¬â¢t make it back? I had never been fishing alone. All I craved was to catch the perfect fish. It didnââ¬â¢t have to be big or fat, just perfect for me. So I mustered up the courage and took a chance. The last time I had taken a chance I had paid for it dearly. à à à à à à à à à à Sarina was the perfect girl, and I was determined to let her know how I felt about her. She didnââ¬â¢t make me happy. Happiness was not exactly the emotion she brought out in me. Her presence brought out something within me that was much deeper and more sincere. She was the foundation of my utopia. She had a special quality about her. Most people I know walk around with their souls being held prisoner by their bodies. She was one of those unique people whose body was held captive by her soul. Thirty seconds out of every minute I thought about her. I always made sure she had everything. It took me six months before I could even tell her how I felt. When I finally told her how I felt she took the news really well, but I knew she wasnââ¬â¢t interested. After telling me that our friendship was too close for us to get involved romantically, I swept up the pieces of my shattered heart, put them in my pocket and walked away. I had her snagged on my hook but she thr ew it. I used kindness, and patience, and she used me. I gave her everything she asked of me. She took the bait and ran. She avoided me at all costs for the next two months. Suddenly, I was at the mercy of the wide-open water of my misery, and was fearful of drowning. Had I been coerced into believing we were best friends? We squandered for hours and hours resolving each otherââ¬â¢s personal dilemmas. We called each other religiously on the phone when we were apart.

Let us assume that the operand stored at memory location 3000H is 85H. The operand is moved to accumulator from memory location 3000H. Then, its complement is found by using CMA instruction. One is added to accumulator by incrementing it to find its 2ââ¬â¢s complement. The result is stored at memory location 3001H. Program (ii. a): Explanation: This program finds the 1ââ¬â¢s complement of 16-bit number stored in memory 3000H3001H. There is no direct way to find 1ââ¬â¢s complement of 16-bit number.Therefore, this can be accomplished by finding the 1ââ¬â¢s complement of two 8-bit numbers. Let us assume that the operand stored at memory locations 3000H-3001H is 45H-6AH. The operand is loaded into H-L pair from memory locations 3000H-3001H. The lower-order is moved from register L to accumulator. Its complement is found by using CMA instruction. The result obtained is moved back to register L. Then, the higher-order is moved from register H to accumulato r. Its complement is found by using CMA instruction. The result obtained is moved back to register H. Now, the final result is in H-L pair. 12 The result is stored from H-L pair to memory locations 3002H-3003H. Program (ii. b): Explanation: ? ? ? ? ? ? ? ? ? ? ? ? ?
