Performance appraisals are conducted yearly for each staff employee. Semiannual or quarterly reviews are recommended to foster better communication between supervisors and employees in assessing progress, jointly developing new plans and objectives, and clarifying expectations for the coming year. This process is designed to improve job understanding, promote more effective job performance, and establish future goals for career growth. Some goals of the performance appraisals are to provide staff members with feedback on their performance and accomplishments for the previous year. This program should also assist staff members in understanding their job responsibilities and supervisor's performance expectations. Performance goals for the upcoming year and specific plans to help staff members meet those goals should also be established through this process. During each annual appraisal conference the employee and supervisor review the employee's performance during the previous year measured against standards set at the start of the year. Both successes and failures are reviewed. It is constructive to take the time to understand why certain objectives were successfully achieved and what prevented the successful achievement of other objectives. This review helps to set and achieve new objectives in the year ahead.

DELIMITATION OF THE STUDY. Researcher has tried to type, print and bind this proposal by using his pocket money. CHAPTER TWO 1. LITERATURE REVIEW. This chapter will provide a range of reviewed literature which will be relevant to the study which will speculate school environment in relation to performance of mathematics subject in Kimala secondary school. THE LACK OF TEACHING AND LEARNING MATERIALS AFFEC T MATHEMATICS PERFORMANCE.Anderson, B (1990:2) stated that, ââ¬Å"Kilimanjaro region success in education sector is made possible by the donor who funded school teaching materials like mathematics books. Though Kilimanjaro region became the second after Dar-es-Salaam. â⬠some schools in Kilimanjaro including Kimala secondary school receive support from world food program, international fund for agriculture development and other organizations which all together helps to feed schools and most students even those who are found among secondary schools in Kilimanjaro do not turn back home until they use evening time for studies.Mwendapole (2009:4) Reported that, ââ¬Å"half of the students who attempted leaving certificate examination failed the Mathematics subject, as the minister for educational and vocation training announced publicly through radio and television. â⬠The ministerââ¬â¢s report showed that most students performed poorly in Mathematics subject. This was the indication that there is lack of teaching and learning facilities like Mathematics books, Mathematics teaching aids like manila and others.According to Ahiakwo, M. J (1989:295-6), A Crisis in the school of some countries is being caused by irrelevant curricula, in adequately trained teachers, lack of teaching materials such as Mathematics text books which are designed for use in teaching as whole or part of particular study course, reference books which are designed for use in teaching as whole or part of particular study course, reference books which contain collected information. Wickliffe N.J (1997:181) Said, drawings combine the features of both picture and charts in that they represent something that is real and at the same time, do so in form of summary, drawings are symbolized summaries of the real earth and it is important to remember this, for symbolism is code and children need to be taught to reach such codes. This significance of objects is depicting the whole situation of lacking in English teaching in secondary schools in Tanzania. CHAPTER THREE 2. RESEARCH METHODOLOGYThe research design was used especially cross section research design where the information for study was collected on time in which both question for students ad interview for the head of the school and academic matter were used. The researcher was able to access many people so that he made genuine interpretation and generalization to other subject by using this research design. Also the researcher was able to spend few hours to complete the whole process of collecting data by using survey research. 3. 1. INTRODUCTIONThe researcher will use the questionnaires method which includes both open and closed questions and the observation method whereby he will visit Kilimanjaro secondary school. The targeted population will be considered 3. 2.

The Physics of Roller Coasters Essay - 1483 Words
The Physics of Roller Coasters The roller coaster has its beginnings in Russia where during the 1600s. People crafted sleds out of wood and built hills made of ice blocks. The hills had sand at the bottom to help slow down the sleds so they would not crash when they reached the bottom of the hill.1 Over time, the roller coaster has become more complex. They now are taller, faster and are designed out of different materials like wood and steel. Although roller coasters are fun and exciting, the questions, what allows them to twist and turn, go up and down hills at a fairly good speed? Why do they not fall off of the track when it goes through a loop? The answer to these questions and others about roller coasters lies in the applicationâ⬠¦show more contentâ⬠¦Then as the coaster begins its decent down the first hill, the energy is converted back into kinetic energy as the train is pulled toward the Earth by gravity. Gravity is the traditional source of power for roller coasters that accelerates the train as i t goes on its hilly, twisty journey.3 Gravity is a unit of acceleration, that is always present, that causes free-falling objects on Earth to change their speed at a rate of approximately 10 m/s (32ft/s) every second.1 So, as the train goes down the hills of the track it has a positive acceleration giving it the necessary potential energy to ââ¬Å"climbâ⬠the next hill, make a turn, or travel through a loop. Also, as the train goes down the hills and loops, it experiences a free fall effect. This occurs when an object falls and is not inhibited by other objects2 (314-315). As the train goes down the hill, the coastersââ¬â¢ mass causes it to accelerate faster than the people in the car. During the free fall stages of the ride the train does not exert any pressure on the riders or the track causing the riders to feel momentarily weightlessness. This is why the train has wheels on the bottom of the track and the passengers of the train have some sort of restraining device to hold them into their seats.3 So, as the train goes down the hill it is actually falling, causing the velocity of the train to increase due to theShow MoreRelatedRoller Coaster Physics1483 Words à |à 6 PagesIndividuals love to go to the amusement parks and try out the rides that are available. The most common and thrilling ride is the roller coaster. An amusement park is not an amusement park if it does not contain a roller coaster.

For instance, you may go to Six Fla gs and do not analyze how physics helps the machines you ride in operate. Have you ever asked yourself how a roller coaster works? Would roller coasters safely run without the knowledge that physics offers us? The answer is no. Roller coasters are driven by physics; it mobilizes and gives its riders amusement through forces such as inertia, gravitationRead MoreThe Physics Of Roller Coasters1209 Words à |à 5 PagesEver since the first commercial roller coaster was built in the United States in 1884, roller coasters have been seen in amusement parks all around the world. These rides, seen in all shapes and sizes, are widely recognized for their thrills. At sudden twists and turns, riders experience large levels of excitement. But what makes a roller coaster so exciting? The answer is physics. In the process of designing roller coasters, engineers use concepts such as Newtonââ¬â¢s three laws of motion to makeRead MorePhysics Principles Of Roller Coasters1047 Words à |à 5 Pagesresearch topic was about the different physics principles that apply to roller coasters. I am to state not only the different types of principles but as well some laws of physics. Roller coasters are not an easy thing to build, one can yes build it but in order to make it succeed there are many ideas that come together and many calculations. I selected this topic because I never paid much attention to all of that work engineers have to do in order to make a roller coaster successful and also because I seeRead More Physics of Roller Coasters Essay1752 Words à |à 8 Pages Roller coasters are driven almost entirely by inertial, gravitational and centripetal forces. Amusement parks keep building faster and more complex roller coasters, but the fundamental principles at work remain the same. A roller coaster is like train. It consists of a series of connected cars that move on tracks. But unlike a passenger train, a roller coaster has no engine or power source of its own. For most of the ride, a roller coaster is moved only by the forces of inertiaRead MorePushing the Sensory Human Experience: The Physics of Roller Coasters1469 Words à |à 6 Pagesexperience? Physics allows roller coasters to give the human an adrenaline rush. With physics, engineers are able to mathematically calculate each experience a rollercoaster has without even having the rollercoaster built yet. The equations of the rollercoasters allow the engineer to know the forces released on the body, the speed and acceleration of the train, the energy lost due to friction and the resistance.
